INFORMATION REGARDING FORWARD-LOOKING STATEMENTS

Some of the information in this Annual Report on Form 10-K contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. The words “believe,” “expect,” “anticipate,” “project,” and similar expressions, among others, identify forward-looking statements. Forward-looking statements speak only as of the date the statement was made. Such forward-looking statements are subject to uncertainties and other factors that could cause actual results to differ materially from those projected, anticipated or implied. Certain factors that might cause such a difference include, among others, the Company’s risks associated with its ability to refinance its credit facilities on satisfactory terms, overall or regional economic conditions, dependence upon affiliated dental practices, contracts its affiliated practices have with third-party payors, dependence upon service agreements and government regulation of the dental industry, the impact of any terminations or potential terminations of such contracts, fluctuations in labor markets and the Company’s acquisition and affiliation strategy. Additional risks, uncertainties and other factors are described in Item 1A.

PART I

As used in this Annual Report, unless otherwise indicated, the terms the “Company”, “we”, “us” and “our” refer to American Dental Partners, Inc. and its wholly-owned subsidiaries. The term “practice” or “dental group practice” refers to a dentist-owned professional corporation, professional association or service corporation which is responsible for providing dental care to patients. An “affiliated practice” or an “affiliated dental practice” is a professional corporation, professional association or service corporation which is not owned by us that has entered into a long-term service agreement with us. An “affiliated dental group” is comprised of an affiliated practice and a Company-owned service company entity which have entered into a long-term service agreement. An affiliated dental group typically comprises several dental facilities in a given metropolitan market. The terms “affiliated practice,” “affiliated dental practice” and “affiliated dental group” also include Arizona’s Tooth Doctor for Kids, a corporation that is 85% owned by us and, as permitted by applicable state law, employs dentists. Consequently, there is no service agreement between Arizona’s Tooth Doctor for Kids and us (see “Item 1. Business – Arizona’s Tooth Doctor for Kids”).

ITEM 1. BUSINESS

Overview

American Dental Partners is a leading provider of dental facilities, support staff and business services to multidisciplinary dental group practices in selected markets throughout the United States. We are committed to the success of the affiliated practices, and we make substantial investments to support each affiliated practice’s growth. We provide or assist with organizational planning and development; recruiting, retention and training programs; quality assurance initiatives; facilities development and management; employee benefits administration; procurement; information systems and practice technology; marketing and payor relations; and financial planning, reporting and analysis. At December 31, 2008, we were affiliated with 25 dental group practices, comprising 545 full-time equivalent dentists practicing in 241 dental facilities in 18 states. We were incorporated in Delaware in 1995.

Dental Care Industry

The market for dental care is large, growing and highly fragmented. Based on Centers for Medicare & Medicaid Services statistics, estimated expenditures for dental care grew 7% annually from 1990 to 2007 reaching $95 billion in 2007. Expenditures for dental care are expected to be approximately $170 billion by 2017, representing a 6% annual growth rate from 2007 to 2017. We believe that the growth in expenditures for dental care will continue to be driven by both increases in costs and increases in demand for services due to:

•

increased enrollment in dental benefits plans, particularly preferred provider organization (“PPO”) plans, and to a lesser extent, dental referral plans;

•

increased demand for dental care as a result of the aging population and a greater percentage of the population retaining its dentition; and

•

increased demand for aesthetic dental procedures as a result of an increasing awareness of personal appearance and the development of new dental materials and procedures which address these desires.

We believe that this growth will benefit not only dentists, but companies that provide services to the dental care industry, including dental management service organizations. However, the failure of any of these factors to materialize could offset increases in demand for dental care, and any such increases may not correlate with growth in our business.

Unlike many other sectors of the health care services industry, the dental care profession remains dominated by practices owned and operated by just one dentist. According to the American Dental Association (“ADA”), in 2005, approximately 63% of the 160,000 dentists in the United States were solo practitioners. The percentage of graduating dentists who initially began their career as an owner of a dental practice, however, fell from 22% in 2002 to 19% in 2006 according to the ADA. We believe a greater percentage of dentists will practice as partners or associates in group dental practices rather than practicing as a solo practitioner as a result of high educational debt levels and a change in gender profile of graduating dentists. According to the ADA, dental students in 2006 graduated with an average of $247,000 of debt and 43% were female. We believe group dental practice provides economic and professional flexibility advantages to graduating dentists as compared to solo practice.

Most dental care performed in the United States is categorized as general dentistry. According to the ADA, in 2006, approximately 79% of dentists were general dentists. General dentistry includes preventative care, diagnosis and treatment planning, as well as procedures such as fillings, crowns, bridges, dentures and extractions. Specialty dentistry, which includes endodontics, oral surgery, orthodontics, periodontics, prosthodontics and pediatric dentistry, represented the remaining 21% of practicing dentists.

Historically, dental care was not covered by insurers and consequently was paid for by patients on a fee-for-service basis. An increasing number of employers have responded to the desire of employees for enhanced benefits by providing coverage from third-party payors for dental care. These third-party payors offer indemnity insurance plans, PPO plans, capitated managed care plans and dental referral plans. Under an indemnity insurance plan, the dental provider charges a fee for each service provided to the insured patient, which is typically the same as that charged to a patient not covered by any type of dental insurance. We categorize indemnity insurance plans as fee-for-service plans. Under a PPO plan, the dentist agrees to accept a discounted fee for each service provided based on a schedule negotiated with the dental benefit provider. Under a capitated managed care plan, the dentist receives a fixed monthly fee from the managed care organization for each member covered under the plan who selects that dentist as his or her provider. Capitated managed care plans also typically require a co-payment by the patient. Dental referral plans are not insurance products but are network-based products that provide access to dental care. Typically, a small monthly fee is paid by an individual or employer for a list of dentists who have agreed to accept certain negotiated fees or a discount from their normal fees. Under dental referral plans, full reimbursement for dental care provided is made directly by a patient to the participating dentist, as compared to indemnity, PPO and capitation plans in which some portion of reimbursement is provided by the payor to the participating dentist. We categorize dental referral plans as PPO plans.

The National Association of Dental Plans (“NADP”) and the Delta Dental Plans Association (“DDPA”) estimated that 173 million people, or 57% of the population of the United States, were covered by some form of dental benefit plan in 2007. This compares with 133 million people, or 52% of the population, in 1996. Of the 173 million people with coverage, 55% were covered by PPO plans, 15% by indemnity insurance plans, 12% by publicly funded benefits such as Medicaid, 9% by dental referral plans, 8% by capitated managed care plans and 1% by direct reimbursement plans. The number of people covered by PPO plans increased from 21 million in 1996 to 92 million in 2006, representing an annual growth rate of 16%.

Business Objective and Strategy

Our objective is to be the leading business partner to dental group practices in selected markets throughout the United States. In order to achieve our objective, our strategy is to provide value-added resources and support to each affiliated practice so that each may become the market leading, high quality dental provider of its community. We believe the core attributes of a leading dental group include the following: (i) a common identity and clinical philosophy, (ii) professional recruiting and mentoring programs, (iii) formalized peer review and quality assurance initiatives, (iv) functional and well-maintained dental facilities, (v) advanced information systems and (vi) a qualified local management team with well-defined responsibilities and accountability.

In executing our strategy, we provide dental facilities and support staff to the affiliated practices and provide or assist with organizational planning and development; recruiting, retention and training programs; quality assurance initiatives; facilities development and management; employee benefits administration; procurement; information systems and practice technology; marketing and payor relations; and financial planning, reporting and analysis. In order to execute our strategy successfully we are continually enhancing or expanding our capabilities and resources, including vertical integration of ancillary activities.

We believe that successful execution of our strategy will result in growth from the following areas: (i) assisting affiliated practices to increase their community presence, (ii) affiliating with dental group practices in new communities and (iii) adding additional capabilities or resources to our service offering through the acquisition or development of related businesses. Our objective is to help the affiliated practices grow their patient revenue 8 to 10% annually and to supplement our growth through completion of additional affiliations in new communities. We are constantly evaluating potential affiliations with dental group practices that would expand our business, as well as possible acquisitions of companies that would broaden our business capabilities. Although we have completed many successful practice affiliations and business acquisitions, there can be no assurance that additional affiliation or acquisition candidates can be identified or that they can be consummated or successfully integrated into our operations.

Affiliation Philosophy

We believe that dental care is an important part of an individual’s overall health care. Because the practitioner is best qualified to manage the clinical aspects of dentistry, the provision of dental care must be centered around the dentist. However, current market trends in health care are increasing the complexity of operating a dental group practice. In addition, the principals of many dental group practices are reaching retirement age and are beginning to investigate means for transitioning the non-clinical leadership and management of their dental group practices. Consequently, many are engaging professional consultants to assist with these complexities and challenges, and in certain instances are choosing to affiliate with dental management service organizations that can manage the non-clinical aspects of dentistry and provide the necessary organizational structure, resources and capital for continued growth and success.

We believe that, similar to other sectors of the health care delivery system, the delivery of dental care is fundamentally a local business. Therefore, each affiliated dental group maintains its local identity and operating philosophy. In each affiliation, we strive to maintain the local culture of the affiliated dental group, and we encourage it to continue using the same name, continue its presence in community events, maintain its relationship with patients and local dental benefit providers and maintain and strengthen the existing management organization.

Our affiliation model is designed to create a relationship between the affiliated practice and us that allows each party to maximize its strengths and retain its autonomy. We believe the core values of our relationship with our affiliated practices are shared governance and shared financial objectives, and we have structured our affiliation model to achieve these goals. Shared governance is achieved by the formation of a joint policy board for each affiliated dental group which is comprised of an equal number of representatives from the affiliated practice and us. Together, members of the joint policy board develop strategies and decide on major business initiatives. Shared financial objectives are achieved through the joint implementation of an annual planning process that

establishes the financial performance standards for the affiliated dental group, including the affiliated practice and us. Under our business model, the dentists continue to have sole and complete discretion over clinical decision-making and patient care while we manage the business aspects of the affiliated practice.

Affiliated Dental Groups

From November 1996 (the date of our first affiliation) through December 31, 2008, we have completed 104 acquisition and affiliation transactions, which resulted in affiliations with 25 affiliated dental groups comprising 241 dental facilities in 18 states. On December 31, 2007, our affiliation with PDG, P.A. (“PDG”), the affiliated practice at Park Dental, ended, and on February 29, 2008 we transferred 25 of our 31 Park Dental facilities to PDG as part of a settlement agreement. For additional information, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Litigation Settlement Agreements.” The following table lists our affiliated dental groups as of December 31, 2008.

Operations

Operating Structure

Where permitted by applicable state law, we generally employ the hygienists, dental assistants and administrative staff at each dental facility, but all clinical activities are performed under the supervision of the dentists who are employed by or contracted with an affiliated practice. Each dental facility has a manager who, along with the administrative staff, typically oversees the day-to-day business operations, including facility staffing, patient scheduling, on-site patient billing and ordering office and dental supplies. Each affiliated dental group has a local operations director who oversees all the managers of the dental facilities of a particular affiliated dental group.

Our shared services teams provide administrative and operational support to one or more affiliated dental groups on either a national, regional or local basis. These teams provide or assist in organizational planning and development; recruiting, hiring and training programs; administering employee benefits and processing payroll; developing and maintaining information systems; developing annual operating plans; producing accounting and financial reporting information; developing and maintaining facilities; and marketing. As smaller affiliated dental groups grow in size, they may add local resources to assume some of the support functions provided by shared services teams.

A regional operations director is responsible for monitoring the operating performance of multiple affiliated dental groups in multiple communities. Each regional operations director participates as a member of the joint policy board of each of the affiliated dental groups for which he or she has oversight responsibilities. The regional operations directors are responsible for overseeing the development of annual operating plans and monitoring actual results.

Accreditation Association for Ambulatory Health Care

We have selected the Accreditation Association for Ambulatory Health Care (“AAAHC”) as a means for supporting the quality initiatives of the affiliated dental groups. The AAAHC is a peer-based, not-for-profit organization that is nationally recognized for conducting extensive evaluations of ambulatory health care organizations. The AAAHC evaluates a number of areas in granting accreditation, such as patients’ rights, governance, administration, clinical records, professional development, quality management and improvement and facilities. We work with the affiliated practices to achieve accreditation. Depending on the level of development and organization, achieving accreditation can take several years of preparation. Currently, ten affiliated practices have achieved accreditation status from the AAAHC.

Training and Leadership Development

We believe that our long term success requires a significant investment in the development of people at all levels within the Company and at the affiliated practices. We have both leadership development and skills training programs.

The American Dental Partners Leadership Institute provides both personal and professional development by bringing dentists and management leaders together to develop effective leadership techniques to create work environments that inspire peak performance from team members. The Leadership Institute is conducted on a national basis with dentists and management from multiple affiliated dental groups in attendance. As part of the learning process, participants receive feedback on the climate they create, their leadership styles and their leadership competencies. Feedback is obtained from the leader’s team members through on-line assessment surveys. Survey results are shared with the leader during the program, and personal action plans are created to enhance leadership effectiveness. We believe creating a high performance climate improves morale, lowers staff turnover and improves productivity.

We have also devoted significant resources to develop innovative, proprietary skills training programs. Training programs exist for improving patient service, such as creating a positive patient arrival/departure experience, improving telephone etiquette and managing unhappy patients, and developing business management competencies, such as improving recruiting skills, developing effective mentoring processes and managing time. The programs are modular and are made available at the affiliated dental groups. We have a national training team comprised of training specialists who partner with the leadership of our affiliated groups to assess the job skills and services of each affiliate in order to implement and maintain continuous training and development programs. Once implemented, the affiliated dental groups have on-going sessions with additional modules as they are developed and with new staff members as they join the dental group. We believe that by investing in skills training, we empower our team members to assist the affiliated practices in providing exceptional patient care and service.

Payor Relationships and Reimbursement Mix

Although we believe that the clinical philosophy of each affiliated practice should not be compromised by economic decisions, we recognize that the source of payment for dental services affects operating and financial performance. Generally, we believe it is easier to grow patient revenue within a given community when the payor mix of the affiliated practice is aligned with the payor mix in that community. We help the affiliated practices optimize their revenue by analyzing their payor mix on an ongoing basis, as well as providing assistance with evaluating and negotiating their dental benefit provider contracts for improved reimbursement rates.

We believe it is advantageous to be affiliated with dental group practices that have successfully provided care to patients under all reimbursement methodologies. Since a shift is taking place in the dental benefits market from indemnity insurance plans and capitated managed care plans to PPO plans and dental referral plans, we believe that experience in operating under all of these plans provides an advantage as it relates to increasing community presence. Most of the affiliated practices provide care under traditional fee-for-service plans and non-fee-for-service plans. The following table provides the aggregate payor mix of the affiliated practices for the years ended December 31:


	2008		2007		2006
Fee-for-service	19	%	28	%	31	%
PPO and dental referral plans	70	%	60	%	52	%
Capitated managed care plans	11	%	12	%	17	%

In recent years, many of the affiliated practices have been realigning their reimbursement mix away from deeply discounted dental benefit plans or negotiating improved reimbursement rates. This effort has largely been accomplished with the cooperation of the dental benefit provider community in general. There can be no assurance, however, that this effort will not result in the termination of certain third-party payor contracts between the affiliated practices and dental benefit providers that adversely impact our business, financial condition or results of operations.

Facilities Development and Management

The affiliated practices operate out of dental facilities that in most instances we lease from third-parties under long-term operating leases. Generally, our dental facilities are constructed to be warm, attractive and inviting to patients and typically have between eight and ten operatories or treatment rooms, which accommodate general and specialty dentists, hygienists and dental assistants as well as required support staff. Most of the dental facilities are either located within a professional office or medical building or are a free-standing location.

We assist the affiliated dental groups in improving facility utilization by evaluating existing capacity, identifying expansion opportunities and prioritizing facility upgrades. We acquire or construct each dental facility as appropriate for the local community and add or equip additional operatories to meet increases in demand. We use architectural design services to improve facility design by working with each affiliated dental group to establish defined facility standards. These standards are developed to meet the needs of each affiliated dental group, while creating a consistency across new dental facilities which shortens the site development process and improves productivity of dentists and support staff.

Financial Planning and Financial Information System

We assist the affiliated dental groups with financial planning. In conjunction with each affiliated practice, we develop an annual operating plan for the affiliated dental group which sets specific goals for revenue growth, operating expenses and capital expenditures. Once a plan has been approved by the joint policy board, we measure forecasted and actual financial performance of each affiliated dental group against the annual operating plan.

Our financial information system enables us to measure, monitor and compare the financial performance of each affiliated dental group on a standardized basis. The system also allows us to track and control costs and facilitates the accounting and financial reporting process. This financial system is used with all affiliated dental groups.

Practice Management Systems

The affiliated dental groups use various dental practice management software systems to facilitate patient scheduling, billing patients and insurance companies, assistance with facility staffing and for other practice related activities. Since 2002 , we have been developing Improvis, a proprietary practice management system which replaces Comdent, a legacy software system. Improvis has been designed to include expanded clinical, managerial and financial capabilities. As of December 31, 2008, 19 affiliated dental groups had implemented Improvis at 179 dental facilities. We intend to implement Improvis at four additional affiliated dental groups in 2009. At year end 2008, we were pilot testing Improvis’ electronic dental record phase, and in 2009 we intend to pilot test Improvis’ digital radiography phase. In addition to these phases, Improvis will include orthodontic practice management and management dashboard functionality as future phases. There can be no assurance, however, that we will successfully implement Improvis at additional dental groups during 2009 or that all phases of the system will be successfully developed.

In connection with one of our affiliations, we acquired the rights to Comdent, a practice management system designed for use by multi-specialty dental groups. Comdent has been in continuous use since 1987, and as of December 31, 2008, Comdent was in use at two of the affiliated dental groups. We intend to retire Comdent in 2009. Two of the affiliated dental groups use commercially available practice management systems.

Orthodontic Care Specialists and Deerwood Orthodontics, which exclusively provide orthodontic services, utilize a proprietary practice management system designed specifically for the unique requirements of the orthodontics specialty. We have implemented this orthodontic practice management system at fifteen other affiliated dental groups which have a significant orthodontics practice.

Service Agreements and Affiliation Structure

Except for Arizona’s Tooth Doctor for Kids (see “Arizona’s Tooth Doctor for Kids”), we have entered into a service agreement with each affiliated practice pursuant to which we are responsible for managing all administrative, non-clinical aspects of the dental practice. We anticipate that each new dental practice with which we affiliate will enter into a similar service agreement or become a party to an existing service agreement at the time of affiliation with us. We are dependent on our service agreements for the vast majority of our net revenue. The termination of one or more of our service agreements could have a material adverse effect on us.

Pursuant to the service agreement, the affiliated practice is solely responsible for all clinical aspects of the dental operations of the affiliated dental group. These clinical aspects include recruiting and hiring dentists, selecting, training and supervising other licensed dental personnel and unlicensed dental assistants, providing dental care, implementing and maintaining quality assurance and peer review programs, setting patient fee schedules, entering into dental benefit plan provider contracts and maintaining professional and comprehensive general liability insurance covering the affiliated practice and each of its dentists. We do not assume any authority, responsibility, supervision or control over the provision of dental care to patients. The service agreement also includes non-competition and confidentiality provisions which prohibit the affiliated practice from owning or operating another dental facility or having any interest in any business which competes with us, within the contractually agreed upon service territory.

Pursuant to the service agreement, we are responsible for providing dental facilities, support staff and all services necessary and appropriate for the administration of the non-clinical aspects of the affiliated dental group. These services include assisting with organizational planning and development; providing recruiting, retention and training programs; supporting quality assurance initiatives; providing on-going facilities development and maintenance; administering employee benefits and payroll; procuring supplies and other necessary resources; maintaining necessary information systems; assisting with marketing and payor relations; and providing financial planning, reporting and analysis. As mandated by the service agreement, we along with each affiliated practice establish a joint policy board which is responsible for developing and implementing management and administrative policies. The joint policy board consists of an equal number of representatives designated by us and the affiliated practice. The joint policy board members designated by the affiliated practice must be licensed

dentists currently employed by the practice. The joint policy board’s responsibilities include the review and approval of the long-term strategic and short-term operational goals, objectives and plans for the dental facilities, all annual capital and operating plans, all renovation and expansion plans and capital equipment expenditures with respect to the dental facilities, all advertising and marketing services and staffing plans regarding provider and support personnel. The joint policy board also reviews and monitors the financial performance of the affiliated dental group, including the affiliated practice. The joint policy board also has the authority to approve or disapprove any merger or combination with, or acquisition of, any dental practice by the affiliated practice. Finally, the joint policy board reviews and makes recommendations with respect to contractual relationships with dental benefit providers, as well as patient fee schedules, although these and all other clinical decisions, as enumerated above, remain the exclusive decision of the affiliated practice through its joint policy board members.

The affiliated practices reimburse us for actual expenses incurred on their behalf in connection with the operation and administration of the dental facilities and pay fees to us for management services provided and capital committed. Under certain service agreements, our service fee consists entirely of a fixed monthly fee determined by agreement between us and the affiliated practice in a formal annual planning process. Under certain service agreements, our service fee consists of a monthly fee equal to the prior year service fee and an additional performance fee based upon a percentage of the increase of the amount by which the affiliated practice’s patient revenue exceeds expenses as compared to the prior year. In no event, however, under these service agreements will the total service fee be greater than the affiliated practice’s patient revenue less expenses. Under certain service agreements, our service fee consists of a monthly fee which is based upon a specified percentage of the amount by which the affiliated practice’s patient revenue exceeds expenses. Under a certain service agreement our service fee consists of a fixed monthly fee and an additional performance fee based upon a percentage of the amount by which the affiliated practice’s patient revenue exceeds expenses as compared to the planned amount of the current year. The structure of the service fee, whether comprised of variable, fixed and variable or fixed components, is dependent in part on laws of each state in which we operate. The affiliated practice is also responsible for provider expenses, which generally consist of the salaries, benefits and certain other expenses of the dentists.

Pursuant to the terms of the service agreements, we bill patients and third-party payors on behalf of the affiliated practices. Such funds, as collected, are applied in the following order of priority:

•

reimbursement of expenses incurred by us in connection with the operation and administration of the dental facilities;

•

repayment of advances, if any, made by us to the affiliated practice;

•

payment of monthly service fee to us;

•

payment of provider expenses; and

•

payment of the additional variable service fee, if applicable, to us.

Our service agreements have an initial term of 40 years and automatically renew for successive five-year terms, unless terminated by notice given at least 120 days prior to the end of the initial term or any renewal term. In addition, the service agreement may be terminated earlier by either party upon the occurrence of certain events involving the other party, such as dissolution, bankruptcy, liquidation or our failure, which continues through the applicable notice and cure period, to perform material duties and obligations under the service agreement. In the event a service agreement is terminated, the affiliated practice is required to reimburse us for unpaid expenses incurred in connection with the operation and administration of the dental facilities, repay advances and pay us for unpaid service fees. In addition, the affiliated practice may be required, at our option in nearly all instances, to purchase the unamortized balance of intangible assets at the current book value, repurchase equipment and other assets at the greater of fair value or book value and assume our leases and other liabilities related to the terminated service agreement.

As part of the litigation settlement with PDG, we entered into a transition services agreement effective January 1, 2008. Under the agreement, we provided certain of the same types of services to PDG as we provide under our

other service agreements, including access to our Comdent practice management system, financial reporting and accounting, billing and collection management, human resource, accounts payable and payroll, supplies procurement and other administrative services. These services were provided to the 25 dental facilities transferred to PDG as part of the litigation settlement and to the PDG dentists who were practicing in our dental facilities on a temporary basis. Our services under the agreement terminated on September 30, 2008, PDG has paid fees for the services in the aggregate amount of $19,000,000 in 2008 and reimbursed certain of our expenses. For additional information, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Litigation Settlement Agreements.”

Arizona’s Tooth Doctor for Kids

We own 85% of Arizona’s Tooth Doctor for Kids (“Tooth Doctor”). Tooth Doctor is a dental group practice which provides dental care to children through six locations in metropolitan Phoenix and Globe, Arizona, and approximately 90% of the group’s revenue is derived from PPO health plans that are contracted with the Arizona Health Care Cost Containment System (“AHCCCS”), the state’s Medicaid program. While we employ the Tooth Doctor dentists as permitted by applicable state law, we do not exercise control over, or otherwise influence, their clinical judgment, decisions or practice.

Competition

The dental services industry is highly competitive. There are approximately 24 competing dental management companies in our current service areas that provide business services to dentists and dental group practices through contractual arrangements. The principal factors of competition between dental management companies are their affiliation models, the number and reputation of their existing affiliated practices, their management expertise, the quality of support services provided to the affiliated practices and their financial track record. We believe we compete effectively with other companies that provide business services to dental practices with respect to these factors. The dental practices affiliated with us compete with other dental group practices and individual dentists in their respective communities.

Government Regulation

General

The practice of dentistry is highly regulated, and our operations and those of the affiliated practices are subject to numerous state and federal laws and regulations. Furthermore, we may become subject to additional laws and regulations as we expand into new states, and there can be no assurance that the regulatory environment in which we and the affiliated practices operate will not change significantly in the future. Our ability to operate profitably will depend, in part, upon us and the affiliated practices obtaining and maintaining all necessary licenses, certifications and other approvals and operating in compliance with applicable laws. Future legislative or regulatory changes could have a material impact on us, and violations of federal or state laws can result in criminal, civil and administrative penalties.

We structure our business, operations and contractual relationships in a manner intended to comply with applicable law, but there can be no assurance that applicable laws will not change and will be interpreted in a manner consistent with our interpretation and intent. In light of this, our service agreements provide that if there is any change in any law, regulation, rule or policy, or any ruling or interpretation by any court or other governing body, that materially and adversely affects, or is reasonably likely to affect, the way in which either party is to perform or be compensated under the service agreement, or which makes the service agreement unlawful, then the parties are obligated to use their best efforts to revise their relationship in a way that complies with the applicable regulatory change or ruling and approximates as closely as possible the economic positions of the parties prior to that change or ruling. There can be no assurance, however, that this provision will be enforced if the legality of our service agreement is challenged.

State Regulation

Each state imposes licensing and other requirements on dentists. The laws of almost all states in which we currently operate prohibit, either by specific statutes, case law or as a matter of general public policy, entities not wholly owned or controlled by dentists, such as American Dental Partners, from practicing dentistry, employing dentists and, in certain circumstances, dental assistants and hygienists, exercising control over the provision of dental services, splitting fees or receiving fees for patient referrals. Many states prohibit or restrict the ability of a person other than a licensed dentist to own, manage or control the assets, equipment or facilities used by a dental practice. However, the laws of Arizona permit us to own the dental practice and employ the dentists at Tooth Doctor. The laws of some states prohibit the advertising of dental services under a trade or corporate name and require all advertisements to be in the name of a dentist. A number of states also regulate the content of advertisements of dental services and the use of promotional gift items. These laws and their interpretation vary from state to state and are enforced by regulatory authorities with broad discretion.

Many states’ laws and regulations relating to the practice of dentistry were adopted prior to the emergence of providers of business services to dental group practices like us. As a result, a number of states, including states in which we currently operate, are in the process of reviewing and/or amending their laws or regulations relating to the practice of dentistry and dentists’ business arrangements with unlicensed persons like us. There can be no assurance that any amendments or new laws or regulations, or the interpretation or application of existing or new laws or regulations, will not have a material adverse effect on our business, financial condition and results of operations.

There are certain regulatory issues associated with our role in negotiating and administering managed care contracts. To the extent that we or any affiliated practice contracts with third-party payors, including self-insured plans, under a capitated or other arrangement which causes us or such affiliated practice to assume a portion of the financial risk of providing dental care, we or such affiliated practice may become subject to state insurance laws. If we or any affiliated practice is determined to be engaged in the business of insurance, we may be required to change our contractual relationships or seek appropriate licensure. Any regulation of us or the affiliated practices under insurance laws could have a material adverse effect on our business, financial condition and results of operations. In certain circumstances, through our role in negotiating and administering managed care and other provider contracts, plans or arrangements we are also subject to regulation in certain states as an administrator and must ensure that our activities comply with relevant regulation.

Federal Regulation

The dental industry is also regulated at the federal level to the extent that dental services are reimbursed under federal programs. Participation by the affiliated practices and their dentists in such programs subjects them, and potentially us, to significant regulation regarding the provision of services to beneficiaries, submission of claims and related matters, including the types of regulations discussed below. Violation of these laws or regulations can result in civil and criminal penalties, including possible exclusion of individuals and entities from participation in federal payment programs.

The federal anti-kickback statutes prohibit, in part, and subject to certain safe harbors, the payment or receipt of remuneration in return for, or in order to induce, referrals, or arranging for referrals, for items or services which are reimbursable under federal payment programs. Other federal laws impose significant penalties for false or improper billings or inappropriate coding for dental services. The federal self-referral law, or “Stark law,” prohibits dentists from making referrals for certain designated health services reimbursable under federal payment programs to entities with which they have financial relationships unless a specific exception applies. The Stark law also prohibits the entity receiving such referrals from submitting a claim for services provided pursuant to such referral. We may be subject to federal payor rules prohibiting the assignment of the right to receive payment for services rendered unless certain conditions are met. These rules prohibit a billing agent from receiving a fee based on a percentage of collections and may require payments for the services of the dentists to

be made directly to the dentist providing the services or to a lock-box account held in the name of the dentist or his or her dental group. In addition, these rules provide that accounts receivables from federal payors are not saleable or assignable.

Tooth Doctor and the other affiliated practices are also covered entities under the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”). Among other things, HIPAA includes provisions regarding protection of the privacy of patient-identifiable health information, requiring us to maintain extensive policies and procedures and also includes provisions relating to standards for security of electronic protected health information and electronic transactions. New health information standards, whether implemented pursuant to HIPAA or otherwise, could have a material effect on how we and our affiliated practices handle health care related data and the cost of compliance. Failure to comply with existing or new laws or regulations related to patient health information could result in criminal or civil sanctions

Finally, dental practices are also subject to compliance with federal regulatory standards in the areas of safety, health and access.

Medicaid

Tooth Doctor and three of our other affiliated practices are providers under Medicaid programs in Arizona, Minnesota, New York and Texas. As a result, they must comply with both state and federal Medicaid laws as well as the requirements of their contracts with third-party payors which administer claims and reimbursement under those programs.

Insurance

We maintain insurance coverage that we believe is appropriate for our business, including property, business interruption and general liability, among others. In addition, the affiliated practices are required to maintain, or cause to be maintained, professional liability insurance with us as a named insured. Certain of our insurances are reinsured by a wholly-owned captive insurance company licensed in the state of Vermont. While we believe that our current insurance coverage is adequate for our current operations, it may not be sufficient for all future claims. In addition, the costs, retention levels and availability of certain insurance have fluctuated significantly in recent years, and there can be no assurance that our current insurance coverages will continue to be available in adequate amounts or at a reasonable cost in the future or that reserve levels of our captive insurance company for potential losses below applicable retention levels under certain insurance coverages will be sufficient.

Customers

For the fiscal year ended December 31, 2008, revenue generated from our service agreements with Metro Dentalcare P.L.C., the affiliated practice at Metro Dentalcare, and Wisconsin Dental Group, S.C., the affiliated practice at Forward Dental, represented 20% and 12%, respectively, of our consolidated net revenue. The termination of either service agreement could have a material adverse effect on our business, financial condition and results of operations.

Employees

As of December 31, 2008, we had 2,531 employees, including 35 dentists and 1 medical doctor (representing 34 full-time equivalent dentists), 430 hygienists, 704 dental assistants and 1,365 administrative personnel at our dental facilities, shared service centers and our corporate office. We consider our relationship with our employees to be satisfactory. We do not employ dentists, hygienists or dental assistants in states where laws prohibit us from doing so. As of December 31, 2008, the affiliated practices, excluding Tooth Doctor, employed 315 hygienists, 304 dental assistants and employed or contracted with 622 dentists (representing 511 full-time equivalent dentists).

ITEM 1A. RISK FACTORS

We may not be able to refinance our credit facilities on satisfactory terms

Our revolving credit facility and term loan mature on January 20, 2010 and the current credit markets are very limited and restrictive. Our failure to extend the maturity or to refinance our revolving credit facility and term loan with our existing lenders or others on satisfactory terms will have a material adverse effect on our business, financial condition and results of operations. We may be able to refinance only a portion of our revolving credit facility and term loan, necessitating the issuance of subordinated debt, preferred stock or common stock, or some combination of such securities. Such securities may include interest or dividends, voting rights or other dilutive effects to our existing shareholders.

We are impacted by general economic conditions

benefits at an annual maximum of $1,000 to $1,500. As a result, patients, with or without dental insurance, are financially responsible for a considerable portion of their dental expenditures. With the deteriorating economic conditions initially emanating from consumer indebtedness, consumer spending patterns have changed. Our affiliated practices have observed patients either delaying care or, for those patients with dental insurance, opting for dental procedures that are largely covered by insurance. As are result, revenue growth rates of the affiliated practices have decreased and revenue mix has shifted towards lower cost and lower profitability dental procedures. The effect to us is lower net revenue and lower profit margins. We believe economic conditions will adversely impact us during 2009, although we are unable to predict the likely duration or severity of the current adverse economic conditions or the severity of the effect of those conditions on our business and results of operations. We also believe the current economic conditions will not lessen the dental care needs of patients and therefore will not impact long term trends of the dental care industry.

We are dependent on the performance of the affiliated practices for our net revenue

Our net revenue depends primarily on revenue generated by the affiliated practices. We do not employ dentists, except for Arizona’s Tooth Doctor for Kids, and we do not control the clinical decisions of any of the affiliated practices. There can be no assurance that the affiliated practices will maintain successful operations or that any of the key members of a particular affiliated practice will continue practicing with that practice. Availability of dentists, hygienists or dental assistants could have a material adverse effect on our business. To the extent permitted by state law, each affiliated practice has entered into non-competition agreements and other restrictive covenants with dentists under their employ and we have similar restrictive covenants with Tooth Doctor’s dentists. There can be no assurance that these restrictive covenants will remain in effect in all cases, are or will be sufficient to protect the interests of the affiliated practices or that a court will enforce such agreements. Any material loss of revenue by an affiliated practice, whether due to the loss of existing dentists or the inability to recruit new ones, could have a material adverse effect on our business, financial condition and results of operations.

We are dependent upon the service agreements we have entered into with each of the affiliated practices, except for Tooth Doctor, for substantially all of our revenue. Revenue generated from our service agreements with Metro Dentalcare P.L.C., the affiliated dental practice at Metro Dentalcare, and with Wisconsin Dental Group, S.C., the affiliated practice at Forward Dental, represented 20% and 12%, respectively of our consolidated net revenue in 2008. The termination of either of these service agreements would have a material adverse effect on our business, financial condition and results of operations.

Our net revenue may be adversely affected by third-party payor cost containment efforts

A significant portion of the payments for dental care that is received by the affiliated practices is paid or reimbursed under insurance programs with third-party payors. Third-party payors are continually negotiating the fees charged for dental care, with a goal of containing reimbursement and utilization rates. Loss of revenue by the affiliated practices caused by third-party payor cost containment efforts or an inability to negotiate satisfactory reimbursement rates could have a material adverse effect on our business, financial condition and results of operations.

Some third-party payor contracts are capitated arrangements. Under such contracts, the affiliated practice receives a monthly payment based on the number of members for which they provide care and generally receives a co-payment from the patient at the time care is provided. Such payment methods shift a portion of the risk of providing care from the third-party payors to the affiliated practice. To the extent that patients covered by such contracts require more frequent or extensive care than is anticipated, there may be a shortfall between the capitated payments received by the affiliated practice and the costs incurred to provide such care. Unfavorable utilization under these contracts, as well as termination of such contracts, could have a material adverse effect on our business, financial condition and results of operations.

Our net revenue at Tooth Doctor and three other affiliated practices may be adversely affected by changes in state Medicaid programs

Tooth Doctor is largely dependent upon reimbursements under Arizona’s Medicaid program and three of our other affiliated practices are providers under various state Medicaid programs. Changes in those programs affecting provider eligibility, reimbursement rates or specific dental procedures eligible for reimbursement, or our affiliated practices failure to maintain its authorization as a provider under these programs, or to comply with applicable state and federal law or its contracts with the payors who administer claims and make payments under these programs, could have a material adverse effect on our business, financial condition and results of operations.

Determinations by regulatory authorities could have a material adverse effect on our operations

The dental industry and dental practices are highly regulated at the state and federal levels, as described in “Item 1. Business-Government Regulation.” Many of these laws and regulations vary widely by state. In addition, these laws and regulations are enforced by federal and state regulatory authorities with broad discretion, and our agreements may be subject to review by these authorities from time to time. For example, regulatory authorities in some states in which we operate have obtained a copy of our service agreement for review in the past, and in the future such reviews could result in changes to our service agreements. We do not, and do not intend to, control the practice of dentistry by the affiliated practices or their compliance with the regulatory requirements directly applicable to dentists or the practice of dentistry. However, there can be no assurance that any review of our business relationships, including our relationship with the affiliated practices, by courts or other regulatory authorities, will not result in determinations that could have a material adverse effect on our operations.

Changes in the laws and regulatory environment could have a material adverse effect on our operations

Similarly, there can be no assurance that the laws and regulatory environment will not change to restrict or limit the enforceability of our service agreements. The laws and regulations of some states in which we currently operate or may seek to expand may require us to change our contractual relationships with dental group practices in a manner that may restrict our operations in those states or may prevent us from affiliating with dental group practices or providing comprehensive business services to dental group practices in those states, or may require us to restructure our current or future operations. For example, a bill recently introduced in the Arizona legislature would impose additional specific reporting and other obligations on business entities, such as us, who own dental practices, and there have been efforts in the past to enact legislation which would have restricted our ability to own dental practices in that state. There can be no assurance that similar legislation will not be enacted in the future. Additionally, the Arizona Board of Dentistry has approved changes to certain sedation rules, and those proposed changes were sent to the Governor’s Regulatory Review Counsel for review. Those changes, if ultimately implemented, or other changes to these rules could adversely affect Tooth Doctor.

Our future affiliations or acquisitions may not be completed on acceptable terms or successfully integrated

Our strategy includes expansion through affiliations with dental group practices in new and existing states and the expansion of such affiliated practices. Affiliations involve numerous risks, including failure to retain key personnel and contracts of the affiliated practices and the inability to work successfully with us as a business partner. There can be no assurance that we will be able to complete additional affiliations on acceptable terms and conditions or that we will be able to serve successfully as a business partner to additional practices, and this could adversely affect our business, financial condition or results of operations. In addition, we entered into agreements to amend our revolving credit agreement and our term loan effective October 24, 2008 which limit amounts which can be borrowed to fund affiliations and acquisitions, and as a result the number of new affiliations and acquisitions over the next twelve months will be at levels lower than we achieved in recent years.

We may not realize the expected value of our goodwill and intangible assets

A significant portion of our total assets is represented by goodwill and intangible assets, with the amount expected to increase with future affiliations. In addition, the amortization expense related to definite lived

intangible assets will increase in the future as a result of additional intangible assets recorded in connection with new affiliations. Management performs an impairment test on goodwill and indefinite lived intangible assets at least annually or when facts and circumstances exist which would suggest that the goodwill or indefinite lived intangible asset is impaired. An impairment test on goodwill and definite lived intangible assets is performed when facts and circumstances exist which would suggest that the definite lived intangible asset may be impaired, such as loss of key personnel, change in legal factors or competition. Impairment assessment inherently involves judgment as to assumptions about expected future cash flows and the impact of market conditions on those assumptions. If impairment were determined, we would make the appropriate adjustment to the intangible asset to reduce the asset’s carrying value to fair value. In the event of any sale or liquidation of us or a portion of our assets, there can be no assurance that the value of our intangible assets will be realized. Any future determination requiring the write off of goodwill, indefinite lived intangibles or a significant portion of unamortized intangible assets could have a material adverse effect on our business, financial condition and results of operations.

Our operating results may be adversely affected by professional liability claims against the affiliated practices

The affiliated practices and/or individual dentists in their employ could be exposed to the risk of professional liability claims, and it is possible that such claims could also be asserted against us. With respect to Tooth Doctor, any such claims would likely be asserted against us. Such claims, if successful, could result in substantial damages that could exceed the limits of any applicable insurance coverage. We are named as an insured under the professional liability insurance policy covering the affiliated practices. In addition, we also require each affiliated practice to indemnify us for actions or omissions related to the delivery of dental care by such affiliated practice. However, a successful professional liability claim against an affiliated practice or us could have a material adverse effect on our business, financial condition and results of operations.

A loss of the services of our key personnel could have a material adverse effect on our business

Our continued success depends upon the retention of our senior officers who have been instrumental in our success and upon our ability to attract and retain other highly qualified individuals. The loss of some of our senior officers, or an inability to attract or retain other key individuals, could materially adversely affect us. Continued growth and success in our business depends, to a large degree, on our ability to retain and attract such employees.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

We lease most of our facilities from unrelated third-parties. As of December 31, 2008, we leased or owned 241 dental facilities, three dental labs and 15 local management offices, including our corporate headquarters. Our corporate office is located at 401 Edgewater Place, Suite 430, Wakefield, Massachusetts 01880, in approximately 17,000 square feet of office space occupied under a lease which expires in 2014. We consider our properties in good condition, well maintained and generally suitable and adequate to carry on our business activities. For the year ended December 31, 2008, facility utilization varied from affiliated dental group to affiliated dental group, but overall was at a satisfactory level. The majority of our dental facilities have sufficient capacity to allow for future growth.

ITEM 3. LEGAL PROCEEDINGS

Shareholder Litigation

On or about January 25, 2008, February 4, 2008, February 12, 2008, and March 13, 2008, we and certain of our executive officers were named as defendants in four actions respectively entitled “Oliphant v. American Dental Partners, Inc. et. al.,” civil action number 1:08-CV-10119-RGS, “Downey v. American Dental Partners, Inc. et. al.,” civil action number 1:08-CV-10169-RGS, “Johnston v. American Dental Partners, Inc. et. al.,” civil action

number 1:08-CA-10230-RGS, and “ Monihan v. American Dental Partners, Inc., et. al .,” civil action number 1:08-CV-10410-RGS, all filed in the United States District Court for the District of Massachusetts. The actions each purport to be brought on behalf of a class of purchasers of our common stock during the period August 10, 2005 through December 13, 2007. The complaints allege that we and certain of our executive officers violated the federal securities laws, in particular, Section 10(b) of the Securities Exchange Act, 15 U.S.C. §§ 78, and Rule 10b-5 promulgated there under, 17 C.F.R. § 240.10b-5, by making allegedly material misrepresentations and failing to disclose allegedly material facts concerning the lawsuit by Park Dental Group against PDHC, Ltd., titled PDG, P.A. v. PDHC, Ltd., Civ. A. Nos. 27-CV-06-2500 and 27-CV-07-13030, filed in the Fourth Judicial District of Hennepin County, Minnesota on February 3, 2006 (“PDG Litigation”), and conduct at issue in that action during the Class Period, which had the effect of artificially inflating the market price of our stock. Each complaint also asserts control person claims under Section 20(a) of the Securities Exchange Act against the executive officers named as defendants.

On or about May 29, 2008, the Court appointed the Operating Engineers Pension Fund, as lead plaintiff and its counsel, the law firm of Grant & Eisenhofer P.A., as lead counsel. The Court also ordered that the four pending actions be consolidated under the caption “ In re American Dental Partners, Inc. Securities Litigation ,” civil action number 1:08-CV-10119-RGS. On or about June 5, 2008, one of the original named plaintiffs, W.K. Downey, agreed to enter an order that dismissed his individual claims with prejudice. On September 29, 2008, the Operating Engineers Pension Fund filed with the Court a consolidated amended complaint, which alleges a new class period of February 25, 2004 through December 13, 2007 and asserts violations of the federal securities laws as described above. On December 5, 2008, we and the other defendants filed a motion to dismiss the action. The plaintiff filed an opposition to the motion on January 30, 2009. The Court has scheduled a hearing on the motion in April 2009. Each plaintiff seeks class certification, an unspecified amount of money damages, costs and attorneys’ fees and any equitable, injunctive or other relief the Court deems proper. We are unable to estimate any potential losses with respect to these actions. We intend to defend the matters vigorously.

Derivative Litigation

On or about June 2, 2008, a derivative action was filed in the Suffolk Superior Court of the Commonwealth of Massachusetts on behalf of the Company entitled “ Musselman v. Serrao et al. ,” C.A. No. 08-2444-BLS. The complaint names us as a nominal defendant and certain of our directors and executive officers (collectively, the “ Musselman Individual Defendants”) as defendants. The action was filed without first making a demand on our Board of Directors to address the allegations. The complaint was amended on July 31, 2008. The amended complaint involves factual allegations relating to the PDG Litigation and asserts claims for breach of fiduciary duties, abuse of control, gross mismanagement, waste of corporate assets, and aiding and abetting breaches of fiduciary duties against all of the Musselman Individual Defendants and claims for unjust enrichment and insider selling against some of the Individual Defendants. The relief the complaint seeks on behalf of us includes an unspecified amount of money damages, disgorgement from some of the Individual Defendants, corporate governance changes and any equitable, injunctive or other relief the Court deems proper. Plaintiffs Teresa and Stephen Musselman also seek costs and attorneys’ fees. Because the action is derivative in nature, any damages will be for the benefit of the Company. We are unable to provide a range of potential damages with respect to this action.

On or about July 1, 2008, a derivative action was filed in Middlesex Superior Court of the Commonwealth of Massachusetts on behalf of the Company entitled “ Dyer v. Serrao et al. ,” C.A. No. 08-2417. The complaint names ADPI as a nominal defendant and certain of our present directors and executive officers (collectively, the “ Dyer Individual Defendants”) as defendants. Plaintiff Dyer filed the action without first making a demand on our Board of Directors to address the allegations. The complaint involves factual allegations relating to the PDG Litigation and asserts a claim for breach of fiduciary duty of good faith against all of the Dyer Individual Defendants. The relief the complaint seeks on behalf of the Company includes an unspecified amount of money damages and any equitable, injunctive or other relief the Court deems proper. The plaintiff also seeks costs and attorneys’ fees. Because the action is derivative in nature, any damages will be for the benefit of the Company. We are unable to provide a range of potential damages with respect to this action.

On August 15, 2008, on the joint motion of the parties, the Dyer and the Musselman actions were consolidated and the Dyer action was ordered to be transferred to the Business Litigation Session of Suffolk Superior Court of the Commonwealth of Massachusetts. The Dyer action was received in the Business Litigation Section on September 22, 2008, under the new civil action number 08-4132-BLS1.

On October 3, 2008, the Court granted Plaintiffs’ Motion to Appoint Co-Lead Counsel and Liaison Counsel and for Entry of a Pre-Trial Order. Defendants filed a Motion to Stay Discovery, which the Court granted on November 20, 2008. We, and the Dyer and Musselman Individual Defendants, have brought a motion to dismiss the consolidated action, which was fully briefed and filed with the Court on December 23, 2008. A hearing date on the motion has been scheduled in April 2009. We intend to defend the matter vigorously.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

American Dental Partners is a leading provider of dental facilities, support staff and business services to multidisciplinary dental group practices in selected markets throughout the United States. We are committed to the success of the affiliated practices, and we make substantial investments to support each affiliated practice’s growth. We provide or assist with organizational planning and development; recruiting, retention and training programs; quality assurance initiatives; facilities development and management; employee benefits administration; procurement; information systems and practice technology; marketing and payor relations; and financial planning, reporting and analysis. At December 31, 2008 we were affiliated with 25 dental group practices, comprising 545 full-time equivalent dentists practicing in 241 dental facilities in 18 states.

Our net revenue depends primarily on revenue generated by the affiliated practices. We estimate approximately 85% of the patients of our affiliated practices have dental insurance, and demand for dental care is heavily influenced by dental insurance. In general, dental insurance covers 100% of preventative care, only 80% of basic restorative procedures and 50% of more extensive restorative procedures. In addition, dental insurance often caps benefits at an annual maximum of $1,000 to $1,500. As a result, patients, with or without dental insurance, are financially responsible for a considerable portion of their dental expenditures. With the deteriorating economic conditions initially emanating from consumer indebtedness, consumer spending patterns have changed. Our affiliated practices have observed patients either delaying care or, for those patients with dental insurance, opting for dental procedures that are largely covered by insurance. As are result, revenue growth rates of the affiliated practices have decreased and revenue mix has shifted towards lower cost and lower profitability dental procedures. The effect to us is lower net revenue and lower profit margins. We believe economic conditions will adversely impact us during 2009, although we are unable to predict the likely duration or severity of the current adverse economic conditions or the severity of the effect of those conditions on our business and results of operations.

Acquisition and Affiliation Summary

When affiliating with a dental practice, we customarily acquire selected assets and enter into a long-term service agreement with the affiliated practice. Under our service agreements, we are responsible for providing all services necessary for the administration of the non-clinical aspects of the dental operations. The affiliated practice is responsible for the provision of dental care. Each of our service agreements is for an initial term of 40 years.

During 2008, 2007 and 2006, we completed eight, 14 and 13 acquisition and affiliation transactions, respectively. In four of these transactions, we acquired non-clinical assets and entered into long-term service agreements with the affiliated practices. In one of these transactions, we developed de novo dental facilities rather than acquiring non-clinical assets, and we entered into a long-term service agreement with the affiliated practice. In 27 of these transactions, we acquired non-clinical assets, and the practices were combined with one of our existing affiliated practices and became subject to an existing service agreement. In one of these transactions, we acquired the assets of the practice, Arizona’s Tooth Doctor for Kids (“Tooth Doctor’), and as permitted by applicable state law, Tooth Doctor employs the dentists thus not necessitating a service agreement between us and the affiliated practice. Finally, in one of these transactions, we acquired 100% of the outstanding capital stock of Metro Dentalcare which owned non-clinical assets, and entered into a long term service agreement with an affiliated practice, Metro Dentalcare, P.L.C. These acquisition and affiliation transactions resulted in the addition of seven affiliated practices, 79 dental facilities and 567 operatories. The 2008, 2007 and 2006 acquisition and affiliation transactions, at the time of the transactions, generated $5 million, $109 million and $38 million of patient revenue on an annualized basis, respectively.

We are constantly evaluating potential acquisition and affiliation transactions with dental practices and acquisitions of other dental-related companies that would expand our business capabilities. We entered into

agreements to amend our revolving credit agreement and our term loan effective October 24, 2008 which limit amounts which can be borrowed to fund affiliations and acquisitions, and as a result the number of new affiliations and acquisitions over the next twelve months will be at levels lower than we achieved in recent years.

Litigation Settlement Agreements

In December 2007, we entered into a settlement agreement in which the service agreement with PDG, P.A. was terminated effective December 31, 2007, and we transferred the operating assets of 25 of the 31 Park Dental facilities and the “Park Dental” trade name to PDG. We retained the remaining six dental facilities which were combined with Metro Dentalcare. We also entered into a transition services agreement with PDG to provide services for a period of nine months through September 30, 2008 for $19,000,000. We completed the transition services, received the related $19 million payment and are completing the final steps in the separation of the companies. As a result of these agreements, our results of operations are not comparable and may not reflect the results of operations to be expected in future periods.

Revenue Overview

Net Revenue

Our net revenue includes management fees earned by us pursuant to the terms of the service agreements with the affiliated practices, as well as reimbursement of clinic expenses paid by us on their behalf, and other revenue which includes patient revenue of Tooth Doctor, fees earned by our dental benefits third party administrator (“TPA”), fees earned by our dental laboratory and other miscellaneous revenue. In 2008, other revenue also includes fees earned under the transition services agreement with PDG.

The following table provides the components of our net revenue for 2008, 2007 and 2006 (in thousands):


	2008		2007		2006
Reimbursement of expenses	$	189,500	$	187,260	$	159,932
Business service fees		55,971		64,088		51,945

Revenue earned under service agreements		245,471		251,348		211,877
Other revenue (1)		45,637		27,407		6,040

Net revenue	$	291,108	$	278,755	$	217,917

(1) 2008 includes $17,697 earned from the transition services agreement with PDG (See “Litigation Settlement Agreements”).

Revenues earned from business service fees and reimbursed expenses under the terms of our affiliated dental practice service agreements represented 84%, 90% and 97% of net revenues for the years ended December 31, 2008, 2007 and 2006, respectively. Due to growth in other revenue the declining percentage in 2007 is primarily due to the Tooth Doctor which was acquired in 2006, and the decline in 2008 was due to revenue earned under our transition services agreement with PDG. Both the affiliated dental practices and Company-owned businesses can be affected by changes in the US economy that may influence discretionary spending for dental services not covered by dental benefit plans. The Tooth Doctor business is directly affected by patient services reimbursed by state Medicaid programs.

Fees earned under service agreements include reimbursement of expenses incurred by us on behalf of the affiliated practices in connection with the operation and administration of dental facilities and business service fees charged to the affiliated practices pursuant to the terms of the service agreements for management services provided and capital committed by us. Under certain service agreements, representing 80% of our 2008 business service fees, our business service fee consists of a monthly fee which is based upon a specified percentage of the amount by which the affiliated practice’s patient revenue exceeds expenses. Under certain service agreements,

representing 19% of our 2008 business service fees, our business service fee consists entirely of a fixed monthly fee determined by agreement of us and the affiliated practice in a formal planning process. Under certain other service agreements, representing less than 1% of our 2008 business service fees, our business service fee consists of either a fixed monthly fee and an additional performance fee based upon a percentage of the amount by which the affiliated practice’s patient revenue exceeds expenses as compared to the planned amount for the current year, a specified percentage of patient revenue or a specified percentage of collections on patient revenue. In all instances, the business service fee is negotiated at fair market value for services provided and capital committed by us to the affiliated practices.

The Company’s net revenue from the reimbursement of expenses is accounted for on an accrual basis and is recognized when these expenses are incurred and billed to the affiliated practices. Reimbursement of expenses includes costs incurred by us for the operation and administration of the dental facilities that include salaries and benefits for non-dentist personnel working at the dental facilities (the administrative staff and, where permitted by law, the dental assistants and hygienists), lab fees, dental supplies, office occupancy costs of the dental facilities, depreciation related to the fixed assets at the dental facilities and other expenses such as professional fees, marketing costs and general and administrative expenses.

Other revenue includes patient revenue from the Tooth Doctor, professional services, dental laboratory fees and other miscellaneous revenue.

For additional information on components of our net revenue, see Note 3 of “Notes to Consolidated Financial Statements.”

Patient Revenue of the Affiliated Practices

We believe it is important to understand patient revenue of the affiliated practices. This includes the practices that we do not control, nor own any equity interests in, and are affiliated with us by means of service agreements. We do not consolidate the financial statements of these affiliated practices with ours, and accordingly their patient revenue is not a measure of our financial performance under generally accepted accounting principles because it is not our revenue. It is however, a financial measure we use, along with the patient revenue of Tooth Doctor, to monitor operating performance and to help identify and analyze trends of the affiliated practices which may impact our business. Most of the operating expenses incurred by us, pursuant to service agreements, are on behalf of the affiliated practices in the operation of dental facilities. These expenses are significantly affected by the patient revenue of the affiliated practices.

The affiliated practices generate revenue from providing care to patients and receive payment from patients and dental benefit providers, or payors, under fee-for-service, PPO plans and managed care capitation plans. Patient revenue reflects the amounts billed by an affiliated practice at its established rates reduced by any contractual adjustments and allowances for uncollectible accounts. Contractual adjustments represent discounts off established rates negotiated pursuant to certain dental benefit plan provider contracts with the affiliated practices. While payor mix varies from market to market, the following table provides the aggregate payor mix of all affiliated practices, including Tooth Doctor, for the years ended December 31:


	2008		2007		2006
Fee-for-service	19	%	28	%	31	%
PPO and dental referral plans	70	%	60	%	52	%
Capitated managed care plans	11	%	12	%	17	%

For the affiliated practices that we do not own and are affiliated with us by means of a service agreement, after collection of fees from patients and third-party insurers for the provision of dental care and payment to us of our service fee and reimbursement of clinic expenses incurred by us on their behalf, the amounts remaining are used by these affiliated practices for compensation of dentists and, in certain states, hygienists and/or dental assistants who are employed by these affiliated practices.

The following table sets forth for the years ended December 31, 2008, 2007 and 2006, the patient revenue of all the affiliated practices, patient revenue earned by Tooth Doctor, the amounts due to us under service agreements, and amounts retained by the affiliated practices we do not own for compensation of dentists and, where applicable, other clinical staff (in thousands):


	Twelve Months Ended December 31,				% Change		Twelve Months Ended December 31,				% Change
	2008		2007		% Change		2007		2006		% Change
Patient revenue of affiliated practices:
Platform dental group practices affiliated with us in both periods of comparison	$	322,318	$	305,249	5.6	%	$	363,508	$	331,434	9.7	%
Platform dental group practices that affiliated with us during periods of comparison		93,640		113,222	-17.3	%		54,963		5,967	821.1	%

Total patient revenue		415,958		418,471	-0.6	%		418,471		337,401	24.0	%
Patient revenue of Tooth Doctor		24,438		22,426	8.9	%		22,426		1,539	1,357.2	%

Patient revenue of platform dental group practices affiliated with us by means of service agreements		391,520		396,045	-1.1	%		396,045		335,862	17.9	%
Amounts due to us under service agreements		245,471		251,241	-2.3	%		251,241		211,877	18.6	%

Amounts retained by platform dental group practices affiliated with us by means of service agreements	$	146,049	$	144,804	0.9	%	$	144,804	$	123,985	16.8	%

Same market patient revenue growth was 5.6% for the year ended December 31, 2008 and was comprised of an 8.4% increase in provider hours, 1.5% reduction in provider productivity and the remainder to reduced reimbursement rates received from dental benefit insurers. Same market patient revenue growth for 2008 excludes platform affiliations that occurred after January 1, 2007. Same market patient revenue growth was 9.7% for the year ended December 31, 2007 and was comprised of a 7.0% increase in provider hours, 1.8% improvement in provider productivity and the remainder to improved reimbursement rates. Same market patient revenue growth for 2007 excludes platform affiliations that occurred after January 1, 2006.

Amounts retained by affiliated practices we do not own increased as a percentage of patient revenue of affiliated practices we do not own from 36.6% in 2007 to 37.3% in 2008 primarily due to increased provider compensation. Amounts retained by affiliated practices we do not own decreased as a percentage of patient revenue of affiliated practices we do not own from 36.9% in 2006 to 36.6% in 2007 due to the affiliation with Metro where we employ the clinical staff rather than the affiliated practice.

Financial Presentation of Litigation Settlement

On February 29, 2008, under the terms of a settlement agreement entered into on December 26, 2007 among American Dental Partners, Inc., PDHC, one of our Minnesota subsidiaries, PDG, Dental Specialists of Minnesota, P.A. and Northland Dental Partners, P.L.L.C. to settle outstanding litigation among the parties, we transferred the operating assets of 25 of 31 Park Dental facilities and associated trade names to PDG, forgave

outstanding accounts receivable due from PDG and entered into a transition services agreement with PDG to provide interim management services through September 30, 2008. See “Litigation Expense” for a discussion of how we have accounted for the transactions.

In addition to our actual results, we believe it is necessary to provide a pro forma financial presentation to exclude temporary and non-recurring items related to the litigation settlement as we believe that such pro forma presentation is important to understanding future trends of our underlying and ongoing operations. The pro forma information are non-GAAP financial measures.

The following table reconciles the actual results of operations to our pro forma non-GAAP financial measures for the twelve months ended December 30, 2008 (in thousands except per share amounts):

The pro forma financial tables above exclude the results of operations, and associated business service fees, of the 25 dental facilities transferred to PDG from both periods of comparison, the PDG doctors who practiced temporarily in the dental facilities retained by us and temporary and non-recurring items related to the litigation settlement. Management believes that such pro forma presentation provides a better understanding of our results of operations and potential future trends of our underlying operations.

Net Revenue

Net revenue increased 4.4% to $291,108,000 in 2008 from $278,755,000 in 2007. Net revenue earned under our transition services agreement with PDG represented approximately 6% of our consolidated net revenue in 2008 and net revenue from our service agreement with PDG which terminated effective December 31, 2007 represented approximately 23% of our consolidated net revenue in 2007. Net revenue increased 27.9% to $278,755,000 in 2007 from $217,917,000 in 2006. The increase in 2007 was attributable to an increase in other revenue due to patient revenue earned by Tooth Doctor which was acquired on December 1, 2006, platform affiliations completed during 2007 and 2006, and a 9.1% increase in same market net revenue growth.

Pro forma net revenue increased 18.9% to $273,411,000 in 2008 from $230,011,000 in 2007. This increase was attributable to a full year of net revenue from our affiliation with Metro Dentalcare, affiliation transactions completed in 2007 and an increase in revenue at the Tooth Doctor.

Net revenue derived from our service agreement with Metro Dentalcare P.L.C., the affiliated practice at Metro Dentalcare, represented approximately 21% of pro forma net revenue for 2008 and 7% of pro forma net revenue for 2007. Net revenue from our service agreement with Wisconsin Dental Group, S.C., the affiliated practice at Forward Dental, represented approximately 13% of our pro forma net revenue for 2008 and 14% of pro forma net revenue for 2007. No other service agreement or customers accounted for greater than 10% of our pro forma net revenue. The termination of either of these service agreements could have a material adverse effect on our business, financial condition and results of operations.

Salaries and Benefits

Salaries and benefits expense includes costs for personnel working at the dental facilities, dental laboratory and local and regional shared service centers. At the facility level, we generally employ the administrative staff and, where permitted by state law, the hygienists and dental assistants. We also employ the dentists at Tooth Doctor. The personnel at the local and regional shared service centers support the dental facilities.

Salaries and benefits expense as a percentage of net revenue increased to 43.2% in 2008 from 42.8% in 2007. Salaries and benefits expense as a percentage of net revenue increased to 42.8% in 2007 from 41.9% in 2006. The increase in 2007 was primarily due to our 2006 acquisition of Tooth Doctor where we employ the dentists.

Pro forma salaries and benefits expense as a percentage of pro forma net revenue increased to 43.8% in 2008 from 42.2 % in 2007. The increase is due to the six dental facilities that we did not transfer to PDG as part of the litigation settlement, the Tooth Doctor where we employ the dentists and to a lesser degree at Metro Dentalcare.

Lab Fees and Dental Supplies

Lab fees and dental supplies expense varies from each affiliate to affiliate and is affected by the volume and type of procedures performed.

Lab fees and dental supplies expense as a percentage of net revenue decreased to 14.7% in 2008 from 15.5% in 2007. These expenses are largely impacted by the patient revenue of the affiliated practices, and as a percentage of patient revenue were 10.3% for both 2008 and 2007. Lab fees as a percent or our net revenue decreased to 15.5% for 2007 from 16.1% in 2006 but as a percentage of patient revenue was 10.3% for 2007 and 10.4% for 2006. These decreases are due to a decrease in lab fees and dental supplies as a percentage of patient revenue as a result of the 2007 and 2006 acquisitions and affiliations where patient care involves fewer procedures requiring crowns, bridges and other dental laboratory services.

Pro forma lab fees and dental supplies expense as a percentage of pro forma net revenue decreased to 15.1% of pro forma net revenue in 2008 from 15.8% in 2007. The decrease is due to concerted efforts to manage dental supplies expense across all affiliates and reduced lab fees at our specialty affiliated practices where lab fees are lower than the average for the overall business.

Office Occupancy

Office occupancy expense includes rent expense and certain other operating costs, such as utilities, associated with dental facilities, dental laboratory and the local and regional shared service centers. Such costs vary based on the size of each facility and the market rental rate for dental office and administrative space in each particular geographic market.

Office occupancy expense as a percentage of net revenue increased to 11.6% in 2008 from 11.3% in 2007. Office occupancy expense as a percentage of net revenue decreased to 11.3% in 2007 from 12.1% in 2006. The decrease in 2007 is primarily due to our 2006 acquisition of Tooth Doctor where office occupancy expense is lower as a percentage of net revenue compared to our other affiliated dental groups, a $234,000 lease buy-out payment made during 2006 and, to a lesser extent, improved facility utilization at the affiliated dental groups.

Pro forma office occupancy expense as a percentage of pro forma net revenue increased to 11.9% in 2008 from 11.6% in 2007. The increase is primarily due to the six retained facilities that we did not transfer to PDG as part of the litigation settlement and Barzman, Kasimov & Vieth (“BKV”) where office occupancy as a percentage of net revenue is higher than our other affiliated dental groups.

Other Operating Expenses

Other operating expenses include non-employment related insurance expense, professional fees, marketing costs and other general and administrative expenses.

Other operating expenses increased as a percentage of net revenue to 8.9% in 2008 from 8.4% in 2007. Other operating expenses decreased as a percentage of net revenue to 8.4% in 2007 from 8.8% in 2006. The decrease in 2007 is due to a reduction in other general and administrative expenses, a decrease in professional fees at the affiliated dental groups, and, to a lesser extent, a non-recurring expense in 2006 related to the disposal of undepreciated assets.

Pro forma other operating expenses as a percentage of pro forma net revenue increased to 9.3% in 2008 from 8.7% in 2007. This increase is due to new affiliations completed in 2008, increased administrative expenses at several of our affiliated dental groups and the disposal of undepreciated assets associated with the relocation of a dental facility.

General Corporate Expenses

General corporate expenses consist of compensation and travel expenses for our corporate personnel and administrative staff, facility and other administrative costs of our corporate office and professional fees, including legal and accounting.

General corporate expense as a percentage of pro forma net revenue decreased to 4.2% in 2008 from 5.2% in 2007. General corporate expenses as a percentage of net revenue increased to 5.2% in 2007 from 5.1% in 2006. The increase in 2007 is due to an increase in stock-based compensation expense.

Pro forma general corporate expenses decreased as a percentage of pro forma net revenue to 4.5% for 2008 from 6.3% in 2007. This decrease is due to a reduced incentive compensation expense and reduced administrative expenses.

Stock-based compensation expense was $1,978,000, $1,898,000 and $1,363,000 for the years ended December 31, 2008, 2007 and 2006, respectively. We anticipate these costs to remain relatively unchanged in 2009.

Depreciation

Depreciation expense, including amortization of leasehold improvements, increased to 3.8% of net revenue in 2008 from 3.4% in 2007. Depreciation expense, decreased to 3.4% of net revenue in 2007 from 3.6% in 2006. The decrease in 2007 is primarily due to improved facility utilization at the affiliated practices as well as our 2006 acquisition of Tooth Doctor where depreciation expense is lower as a percentage of revenue compared to other affiliated dental groups.

Pro forma depreciation expense as a percentage of pro forma net revenue increased to 3.9% in 2008 from 3.5% in 2007. The increase was the result of the underutilization of the six retained facilities that we did not transfer to PDG as part of the litigation settlement and 2008 facility investments.

We expect to continue to invest in the development of new dental facilities and the relocation and/or expansion of existing dental facilities in 2009 but at lower levels than we have in past years.

Amortization of Service Agreements and Other Intangible Assets

Amortization expense, principally relating to our service agreements with affiliated practices, as a percentage of net revenue increased to 3.3% in 2008 from 2.5% in 2007. Amortization expense as a percentage of net revenue remained constant at 2.5% for 2007 and 2006. The increase in amortization expense from new affiliations was offset by same market net revenue growth of the affiliated dental groups and our 2006 acquisition of Tooth Doctor where the majority of the purchase price was allocated to goodwill.

Amortization expense as a percentage of pro forma net revenue increased to 3.5% in 2008 from 3.1% in 2007. The increase was due to affiliations completed during 2007, most notably the affiliations with BKV.

Litigation Expense

We accounted for the transactions associated with the PDG litigation (See “Litigation Settlement Agreements”) in 2008 and 2007 as follows:

On February 29, 2008, under the terms of the settlement agreement we transferred the operating assets of 25 of the 31 Park Dental facilities and pursuant to Financial Accounting Standards No. 144 “ Accounting for the Impairment or Disposal of Long-Lived Assets ” (“SFAS 144”) we realized a net gain of $30,763,000 which represents the fair value of the assets transferred in excess of the book value of the assets transferred, insurance proceeds of $1,002,000 for professional fees associated with the PDG litigation which were partially reimbursable pursuant to insurance coverage offset by professional fees and other net expenses associated with the litigation of $1,103,000. In addition, we recorded a management service fee, during 2008, totaling $10,000,000 offset by the costs to provide these services including severance costs.

In accordance with Statement of Financial Accounting Standards No. 5, “ Accounting for Contingencies ” (“SFAS 5”), we accrued a loss contingency of $30,968,000 at December 31, 2007, which is comprised of the following items: (i) $39,968,000 representing the estimated fair value, using discounted cash flows, of the operating assets being transferred and (ii) a reduction of $9,000,000 from the $19,000,000 to be paid by PDG, which represents the amount deemed in excess of the fair market value of the management services to be provided. In addition to this $30,968,000 accrual, litigation expense in our statement of operations is also comprised of the following: (i) $2,035,000 of accounts receivable due from PDG, P.A. that we reserved as part of the litigation settlement and (ii) professional fees associated with the litigation of $3,731,000. Professional fees associated with the litigation of $1,570,000 for the year ended December 31, 2006 have been reclassified from general corporate expenses to litigation expense.

Earnings from Operations

Earnings from operations increased to $60,190,000 in 2008 from a loss of $(6,354,000) in 2007. Earnings from operations decreased to a loss of $(6,354,000) in 2007 from $20,182,000 in 2006. The primary reason for the decrease in 2007 was the litigation expense of $36,734,000 in 2007 and litigation gain in 2008.

Pro forma earnings from operations increased 5.3% to $21,526,000 or 7.9% of pro forma net revenue in 2008 from $20,433,000, or 8.9% of pro forma net revenue, in 2007. The decrease as a percentage of pro forma net revenue is primarily due to increased depreciation and amortization expense, increased salaries and benefits and other operating expenses somewhat offset somewhat by reduced general corporate expenses and lab fees and dental supplies.

Interest Expense

Net interest expense increased to $10,193,000 in 2008 from $5,253,000 in 2007. The increase in interest expense was primarily due to greater borrowings as a result of acquisitions and affiliations completed in 2007 and to a lesser extent higher credit spreads over LIBOR and an increase in amortization of bank fees associated with our credit facility which is now being amortized through January 2010. Net interest expense increased to $5,253,000 in 2007 from $1,848,000 in 2006. Pursuant to Emerging Issues Task Force Issue No. 98-14 “ Debtor’s Accounting for Changes in Line-of-Credit or Revolving-Debt Arrangements ” (“EITF 98-14”), we expensed $851,000 of unamortized deferred financing costs as a result of the forbearance agreement we entered into with our lenders on December 18, 2007. The increase in 2007 in interest expense was due to higher average borrowings. While market rates affecting our variable rate interest declined in 2007, our effective interest rate was comparable to 2006 because of an increase in our borrowing margin as a result of our higher leverage ratios after financing the 2007 acquisition of Metro Dentalcare.

Minority Interest

The increase in minority interest expense in 2008 and 2007 is due to gains attributable to the minority interest holders in the earnings of the Tooth Doctor. In 2008, we acquired the remaining 10% ownership interest from the

minority holders in one of our subsidiaries. In 2006 and 2007, we entered into three platform affiliations in which our subsidiaries had minority owners. For the years ended December 31, 2008, 2007 and 2006, we recorded minority interest expense of $634,000, $390,000 and $54,000, respectively, representing the gains attributable to minority interest holder, net of cumulative losses.

Income Taxes

Our effective tax rate was 39.0% for 2008, 35.7% for 2007 and 39.1% in 2006. The change in 2007 is attributable to the accounting impact associated with the PDG litigation settlement. We expect our 2009 effective tax rate to increase as a result of announced rate increases in certain states in which we operate.

Net Earnings

As a result of the foregoing, net earnings increased to $30,118,000 in 2008 as compared to a loss of $(7,716,000), in 2007. Net earnings decreased to a loss of $(7,716,000) in 2007 from earnings of $11,134,000 in 2006.

Pro forma net earnings decreased 27.4% to $6,528,000, or 2.4% of pro forma net revenue, in 2008 from $8,992,000, or 3.9% pro forma net revenue, in 2007. The decrease as a percentage of pro forma net revenue is due to an increase in interest expense and salaries and benefits somewhat offset by reduced general corporate expenses.

Liquidity and Capital Resources

Overview

We have financed our operating and capital needs, including cash used for acquisitions and affiliations, capital expenditures and working capital, principally from operating cash flows and borrowings under our revolving line of credit and term loan. We have, in the past, also used proceeds from the sale of equity securities and the issuance of subordinated promissory notes to finance certain capital needs, but have not done so in recent years.

Current Credit Market Conditions

The credit markets have recently experienced unprecedented volatility, which has affected both the availability and cost of debt financing. In this current volatile credit environment, we have taken a number of initiatives to maintain our liquidity, including the following:

•

we largely eliminated 2008 incentive compensation expense accruals and as a result cash bonus payments associated with these accruals will be significantly reduced during the first quarter of 2009;

•

we have delayed 2009 compensation increases until the economic environment and our financial performance merit such increases;

•

we have implemented a hiring freeze for non-clinical positions and are evaluating all non-essential positions;

•

we have reduced valuations for affiliations and acquisitions and will complete only those that make both strategic and economic sense; and

•

we have reduced 2009 capital expenditure expectations to approximately $7,000,000.

We have a $75,000,000 revolving credit facility and $100,000,000 term loan, both of which are senior secured facilities, are provided by commercial banks and have maturities of January 20, 2010. The availability of senior secured debt has been significantly reduced in the current credit markets which has resulted in increased borrowing rates, reduced financial covenants and higher upfront fees. To the extent that we are not able to refinance our credit facilities in the senior credit markets or to obtain extensions from our existing lenders, we may need to seek financing from other sources, including the sale of subordinated debt, preferred stock or common stock. These forms of financing may include interest payments, dividend payments and dilutive effects to our existing common stockholders. We cannot assure you that such financing will be available or on terms acceptable to us.

Unless we refinance our credit facilities or obtain extensions from our existing lenders subsequent to December 31, 2008, our existing indebtedness will be classified as a current liability at March 31, 2009.

Operating Activities

For the years ended December 31, 2008 and 2007, cash provided by operating activities amounted to $38,561,000 and $25,574,000, respectively. In 2008, cash from operations primarily resulted from net earnings after adding back non-cash items, a decrease in accrued expenses and a decrease in accrued compensation and benefits and an estimated $9,964,000, net of taxes, from the transition services agreement with PDG that will not reoccur in 2009, partially offset by an increase in accounts receivable. Excluding the impact of the transition services agreement, cash provided by operating activities in 2008 would have been approximately $28,597,000. We are not able to estimate the cash provided by operating activities in 2007 for the service agreement with PDG which terminated effective December 31, 2007 as we transferred only 25 of the 31 dental facilities to PDG. The decrease in accrued compensation and benefits is due to decreases in accrued bonuses and other benefits. The increase in accounts receivable, net, is due to an increase in amounts due from the six locations we retained in the PDG settlement. Days revenue outstanding for patient receivables at the affiliated practices decreased to 35 days as of December 31, 2008 from 38 days as of December 31, 2007. The decrease in days revenue outstanding for patient receivables was primarily due to a continued focus on receivables management at the affiliated practices. For the years ended December 31, 2007 and 2006, cash provided by operating activities amounted to $25,574,000 and $31,050,000, respectively. In 2007, cash from operations primarily resulted from net earnings after adding back non-cash items, an increase in accrued expenses and an increase in accrued compensation and benefits, partially offset by an increase in accounts receivable, net. The increase in accrued expenses is primarily due to an increase in accruals for professional fees associated with the PDG litigation and, to a lesser extent, an increase in accrued professional liability at our captive insurance subsidiary. The increase in accrued compensation and benefits is primarily due to increases in accrued bonuses and other benefits. The increase in accounts receivable, net is due to an increase in amounts due from affiliated practices, which is largely affected by patient receivables at the affiliated practices which increased to 38 days revenue outstanding as of December 31, 2007 from 32 days revenue outstanding as of December 31, 2006. This increase is primarily due to the implementation of Improvis at several of the affiliated dental groups which has historically resulted in a temporary increase in accounts receivable.

Investing Activities

For the years ended December 31, 2008 and 2007, cash used for investing activities amounted to $27,541,000 and $132,852,000, respectively. The net decrease of $105,311,000 in cash used in investing activities is primarily due to a decrease of $114,159,000 in cash used for affiliations and acquisitions in 2007, net of cash acquired, offset by an increase in 2008 of $8,658,000 for contingent and deferred payments. In 2008, cash used for contingent and deferred payments included a contingent payment related to the Metro Dentalcare acquisition of approximately $9,685,000 of which $4,575,000 was accrued as of December 31, 2007. For the years ended December 31, 2007 and 2006, cash used for investing activities amounted to $132,852,000 and $33,902,000, respectively. The net increase of $98,950,000 in cash used for investing activities is primarily due to an increase of $93,245,000 in cash used for acquisitions, net of cash acquired, and an increase in capital expenditures of $4,033,000, and to a lesser extent increases in contingent payments made as part of affiliations and payment of affiliation costs. Cash paid for acquisitions and affiliations increased as a result of the affiliations being larger than those completed in 2006, most notably the acquisition of Metro Dentalcare and the affiliation with BKV. In addition, a contingent payment of approximately $1,300,000, which had been accrued for as of December 31, 2006 was paid in 2007. Capital expenditures increased due to project timing as certain 2006 relocation and/or expansion projects were extended into 2007.

Financing Activities

For the years ended December 31, 2008 and 2007, cash (used)/provided by financing activities amounted to $(10,770,000) and $112,268,000, respectively. The decrease of $123,038,000 in cash provided by financing

activities is primarily due to our term loan borrowing of $100,000,000 in 2007 and increased net repayments on our revolving credit facility of approximately $16,100,000 and to a lesser extent an increase of approximately $1,528,000 of payments for costs associated with our October 2008 amendments to our credit facilities, discussed more fully below. For the years ended December 31, 2007 and 2006, cash provided by financing activities amounted to $112,268,000 and $3,646,000, respectively. The increase of $108,622,000 in cash provided by financing activities is primarily due to our term loan borrowing of $100,000,000 and increased net borrowings on our revolving credit facility of approximately $4,900,000 and to a lesser extent an increase of approximately $3,200,000 in benefits and proceeds from stock option exercises. The increased borrowings were used to fund our acquisition and affiliation activities. Proceeds from the exercise of stock options increased in 2007 due to an increased number of option exercises compared to 2006.

Credit Agreements

In September 2007, we increased the capacity of our revolving credit facility to $130,000,000 and extended the maturity to September 2012, and we entered into a term loan Agreement in the amount of $100,000,000 with a maturity of September 2008. All of the obligations under the term loan facility rank pari passu in right of payment to all of the obligations of our revolving credit facility.

As a result of the outcome of the litigation between PDG and us in December 2007 (See “Litigation Settlement Agreements”), on February 21, 2008, we entered into agreements to amend our revolving credit facility and term loan with our existing lenders. Pursuant to the agreements, the terms of the revolving credit facility and term loan were amended, including a reduction in the revolving credit facility to $75,000,000, establishing the maturity of both facilities at June 30, 2009 and increasing the borrowing costs under both facilities. The amended facilities permitted us to borrow up to $15,000,000 annually for capital expenditures, $15,000,000 annually for acquisitions and up to $13,000,000 for earn out and contingent payments on previously completed acquisitions, subject to a maximum debt to earnings before interest, taxes, depreciation and amortization leverage ratio of 3.75x.

The revolving credit facility and term loan facility were amended on June 11, 2008 to extend the maturity from June 30, 2009 to July 20, 2009. If we had not amended the facilities prior to June 30, 2008 to extend the maturity date beyond June 30, 2009, we would have been required to classify these borrowings as a current versus a long term liability. No other provisions of the loan agreements were amended on June 11, 2008.

On October 24, 2008, we entered into agreements to amend the maturities and borrowing costs of our $75,000,000 revolving credit facility and $100,000,000 term loan with our existing lenders. The maturity of both facilities was extended to January 20, 2010. Borrowings under the revolving credit facility bear interest at either prime or LIBOR plus a margin, at the Company’s option. The margin is based upon our debt coverage ratio and ranges from 4.25% to 4.50% for both prime and LIBOR borrowings. Interest on the term loan is at LIBOR plus a margin. The margin is 450 basis points from October 24, 2008 until February 28, 2009 and increases 50 basis points each 90 days thereafter. We pay a commitment fee on the unused balance of our revolving credit facility ranging from 0.375% to 0.5%. Borrowings are limited to an availability formula based on earnings before income taxes, depreciation and amortization, adjusted for certain items, to a maximum of 3.75x and are secured by a first lien on substantially all of our assets, including a pledge of the stock of our subsidiaries. The outstanding balance under this line as of December 31, 2008 was $31,100,000, and we had stand-by letters of credit amounting to approximately $1,669,200 at December 31, 2008. At December 31, 2008 the LIBOR-based and prime interest rate for the term loan was 8.48% and ranged from 4.98% to 9.25% for the revolving line of credit. On December 31, 2008 we were in compliance with all credit agreements covenants.

On May 9, 2007, we entered into an interest rate swap to hedge $20,000,000 of our borrowings under the revolving credit facility. Under this arrangement, we have effectively converted our 3-month, floating LIBOR interest rate exposure, plus a credit spread, to fixed 5.0%, plus a credit spread, until February 2012.

Contractual Obligations

A summary of our contractual obligations as of December 31, 2008 is as follows (in thousands):


	Payments due by period
	Total		2009		2010-2011		2012-2013		Thereafter
Long-term debt (1)	$	536	$	196	$	340	$	-	$	-
Revolving credit facility and term loan (2)		131,100		-		131,100		-		-
Operating leases (3)		95,537		18,325		29,121		20,672		27,419
Uncertain tax positions (4)		434		-		-		-		434

Total	$	227,607	$	18,521	$	160,561	$	20,672	$	27,853

(1) In addition to these contractual obligations, future interest payments relating to our long-term debt are fixed at rates between 5% and 7% and are due as follows: $24,000 in 2009 and $19,000 in 2010-2011.

(2) Future interest obligations relating to our revolving credit facility and term loans are not determinable as the interest rates are variable and the agreements do not include a required principal repayment schedule. In 2007 we hedged $20,000,000 of our market interest rate exposure at 5% plus a credit spread resulting in minimum expected payments of $1,000,000 per year through 2009.

(3) Operating lease payments include amounts which are to be reimbursed to us pursuant to the terms of our service agreements with the affiliated practices. The amounts to be reimbursed by the affiliated practices are $84,908 and are due as follows: $16,309 in 2009, $25,504 in 2010-2011, $18,130 in 2012-2013, and $24,966 thereafter.

(4) Uncertain tax positions are taken or expected to be taken on an income tax return that may result in additional payments to tax authorities. The amount in the preceding table includes interest and penalties accrued related to such positions as of December 31, 2008. The total amount of uncertain tax positions is included in the “Thereafter” column as we are not able to reasonably estimate the timing of potential future payments. If a tax authority agrees with the tax position taken or expected to be taken or the applicable statute of limitations expires, then additional payments will not be necessary.

In certain affiliation or acquisition transactions we may be obligated to make deferred or contingent payments. Typically, these payments are based upon the achievement of revenue or earnings for an agreed upon period after the transaction. The potential future payments under these agreements cannot exceed $1,917,000 in 2009, $2,327,000 in 2010-2011 and $125,000 in 2012.

Critical Accounting Policies and Estimates

The preparation of consolidated financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an on-going basis management evaluates its estimates, including those related to the carrying value of goodwill, receivables due from affiliated practices, other intangible assets, loss reserves for our captive insurance company and contingent accruals for litigation in accordance with Statement of Financial Accounting Standards No. 5. Management bases its estimates on historical experience, on various other assumptions that are believed to be reasonable under the circumstances and in certain instances actuarial studies conducted by third parties, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We have identified the policies below as critical to our business operations and the understanding of our results of operations.

Valuation of Accounts Receivable

Our accounts receivable include amounts due from affiliated practices that have entered into service agreements with us and amounts due from insurance companies, patients and dentists for our Tooth Doctor, dental benefits third party administrator and dental laboratory businesses. At December 31, 2008, amounts due from affiliated practices represented 85% of our accounts receivable.

The carrying amount of receivables due from affiliated practices requires management to assess the collectability of the fees we earn pursuant to the service agreements. Collection of our service fees are dependent on the economic viability of the affiliated practices based on actual and expected future financial performance including collectability of the affiliated practices’ patient receivables, net of contractual adjustments and allowances for doubtful accounts. The affiliated practices record revenue at established rates reduced by contractual adjustments and allowances for doubtful accounts to arrive at patient revenue. Contractual adjustments represent the difference between gross billable charges at established rates and the portion of those charges reimbursed pursuant to certain dental benefit plan provider contracts. For contracts where there is no defined benefit, contractual adjustments are based upon historical collection experience and other relevant factors. The affiliated practices’ provision for doubtful accounts is estimated in the period that services are rendered and adjusted in future periods as necessary. The estimates for the provision and related allowance are based on an evaluation of historical collection experience, the aging profile of the accounts receivable, write-off percentages and other relevant factors. Changes in these factors in future periods could result in increases or decreases in the provision. In the event that final reimbursement or bad debt experience differs from original estimates, adjustments to the affiliated practices’ patient receivables would be required which could impact the collectability of our receivables due from affiliated practices.

Except for accounts receivable due from PDG which we agreed to forgive pursuant to settlement of outstanding litigation, to date we have not recorded any losses related to our receivables due from affiliated practices and accordingly have not recorded any reserves for uncollectability. We have recorded reserves for uncollectability against accounts receivable of our Tooth Doctor, dental benefits third party administrator and dental laboratory businesses based on historical collection experience, the aging profile of the accounts receivable, write-off percentages and other relevant factors.

Goodwill and Intangible Assets

We have intangible assets, including goodwill and other identifiable intangibles assets, which are the result of affiliation transactions and acquisitions of businesses. The initial identification and valuation of these intangible assets and the determination of useful lives at the time of affiliation or acquisition involve the use of management judgments and estimates. These estimates are based on, among other factors, reviews of projected future income, cash flows and statutory regulations. At December 31, 2008, intangible assets were $252,000,000 and represented 71% of our total assets, and goodwill and indefinite-lived intangible assets representing 30% of our intangible assets and definite-lived intangible assets related to service agreements representing 70% of our intangible assets.

Our affiliations with dental group practices as a result of the parties entering into a service agreement are not business combinations, and as such, do not result in recognition of goodwill. We recognize capitalized service agreement costs which are accounted for as definite-lived intangible assets acquired in affiliations other than a business combination, and are recorded at fair value. In determining the fair value of a service agreement recognized in connection with an affiliation, management estimates the timing, amount and value of future expected cash flows. These service agreements have contractual terms of 40 years but the asset is generally amortized on a straight-line basis over a period of 25 years. In the event a service agreement is terminated, the related affiliated practice is required, at our option in nearly all instances, to purchase the remaining unamortized balance of intangible assets at the current book value, purchase other assets at the greater of fair value or book value and assume leases and other liabilities related to the performance of our obligations under the service agreement.

We review identified intangible assets with defined useful lives and subject to amortization for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Determining whether an impairment loss occurred requires comparing the carrying amount to the sum of undiscounted cash flows expected to be generated by the asset group.

We test goodwill for impairment annually as of October 1 and whenever events or circumstances make it more likely than not that the fair value of a reporting unit has fallen below its carrying amount, such as a significant adverse change in the assets utilized by the business. Determining whether an impairment has occurred requires

valuation of the respective reporting business unit, which we estimate using a discounted cash flow method. When available and as appropriate, we consider market multiples to supplement the discounted cash flow analysis. In applying this methodology, we rely on a number of factors, including actual operating results, future business plans, economic projections and market data. If this analysis indicates goodwill is impaired, measuring the impairment requires a fair value estimate of each identified tangible and intangible asset. In this case, we would supplement the cash flow approach discussed above with independent appraisals.

We tested goodwill for impairment as of October 1, 2008 which included various scenarios with varying revenue, expense and capital investment assumptions and determined there was no impairment of goodwill and indefinite lived intangible assets. Subsequent to the annual testing, our market capitalization decreased significantly to below its book value. We believe that this decline was the result of the financial markets’ reaction to the nation’s deteriorating economic conditions and concerns about our ability to renegotiate our revolving credit facility and term loan facility. In view of these developments, we reviewed our operating results subsequent to October 1, 2008 which included financial and key operating metrics as well as available market data, and concluded that an interim impairment test was not warranted. There can be no assurance, however, that further deterioration of economic conditions will not materially or adversely effect our operations. Should the fair value of the Company’s goodwill or indefinite lived intangible assets decline because necessary changes in assumptions of our impairment tests, or other circumstances that may indicate impairment, recognition of impairment may be necessary in the future which could be material.

While we believe we have made reasonable estimates and assumption to calculate the fair value of the reporting units and other intangible assets, it is possible a material change could occur in the future. If our actual results are not consistent with our estimates and assumptions, we may be required to perform the second step of the impairment analysis, which could result in a material impairment of our goodwill or other intangible assets.

Insurance

We maintain various insurance coverages that we believe are appropriate for our business, including workers’ compensation, property, business interruption and general liability, among others. In addition, the affiliated practices are required to maintain, or cause to be maintained, professional liability insurance with us as a named insured. Certain of our insurances are reinsured by a wholly-owned captive insurance company licensed in the state of Vermont. Several of these insurance programs have retention levels in which we and our captive insurance company are financially obligated for insured losses below certain financial thresholds before the insurer is financially obligated for insured losses. We and our captive insurance company maintain reserves for certain of these programs, which are based upon estimates provided by third-party actuaries or by individual case-basis valuations. Changes in trends of loss severity or loss frequency may affect the calculation of these estimates and create the need for subsequent adjustments to estimated loss reserves.

Stock-Based Compensation

We account for stock-based compensation in accordance with the fair value recognition provision of SFAS No. 123(R). We use the Black-Scholes option-pricing model, which requires the input of subjective assumptions. These assumptions include: estimating the length of time employees will retain their vested stock options before exercising them (expected life), the estimated volatility of our common stock price over the expected life (volatility), and the number of options that will ultimately not complete their vesting requirements (forfeitures). Changes in these assumptions for future stock option grants can materially affect the estimate of the fair value of stock-based compensation.

Income Taxes

Our annual tax rate is based on statutory tax rates and tax planning opportunities available to us in the various jurisdictions in which we operate. Tax laws are complex and subject to different interpretations by the taxpayer and respective governmental taxing authorities. Significant judgment is required in determining our tax expense and in evaluating our tax positions, including evaluating uncertainties under FASB Interpretation No. 48, “ Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement 109 ” (“FIN 48”). FIN 48 clarifies the accounting for income taxes by prescribing a minimum recognition threshold a tax position is

required to meet before being recognized in the financial statements, and also provides guidance on the de-recognition, measurement classification, interest and penalties, accounting in interim periods and disclosures. We review our tax positions quarterly and adjust the balances as new information becomes available.

Deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory rates applicable to future years to differences between the consolidated financial statement carrying amounts and the tax basis of existing assets and liabilities, as well as from net operating loss and tax credit carry forwards. We evaluate the recoverability of these future tax deductions and credits by assessing the adequacy of future expected taxable income from all sources, including reversal of taxable temporary differences, forecasted operating earnings and available tax planning strategies. These sources of income inherently rely heavily on estimates. We use our historical experience and our short and long-range business forecasts to provide insight. To the extent we do not consider it more likely than not that a deferred tax asset will be recovered, a valuation allowance is established.

We are subject to income tax arising from U.S. federal and multiple state jurisdictions. In the normal course of business, we are subject to examination by U.S. federal and state taxing authorities. The tax years 2006, 2007 and 2008 remain open to examination, and on October 7, 2008, the Internal Revenue Service notified us that it will examine our federal income tax return for the year ending December 31, 2006.

Our policy for recording interest and penalties associated with audits is to record such items as a component of income before taxes. For the year ended December 31, 2008, $42,000 of interest expense and $78,000 of tax expense related to penalties were recognized in the statement of earnings, compared with $24,000 and $80,000, respectively, for the year ended December 31, 2007.

Recent Accounting Pronouncements

In December, 2007 the FASB issued SFAS No. 141(R) “ Business Combinations ” (“SFAS 141(R)”). SFAS 141(R) introduces significant changes in the accounting for and reporting of business acquisitions. SFAS 141(R) continues the movement toward the greater use of fair values in financial reporting and increased transparency through expanded disclosures. SFAS 141(R) changes how business acquisitions are accounted for and will impact financial statements at the acquisition date and in subsequent periods. In addition, SFAS 141(R) will impact the annual goodwill impairment test associated with acquisitions that close both before and after its effective date. SFAS 141(R) applies prospectively to fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. An entity may not apply SFAS 141(R) before that date. The Company expects no material effect at the adoption date. However, upon adoption, this statement may materially affect the accounting for future business combinations.

In December 2007, the FASB issued SFAS No. 160, “ Noncontrolling Interests in Consolidated Financial Statements – an amendment of Accounting Research Bulletin No. 51 ” (“SFAS 160”). SFAS 160 establishes accounting and reporting standards for ownership interests in subsidiaries held by parties other than the parent, the amount of consolidated net income attributable to the parent and to the noncontrolling interest, changes in a parent’s ownership interest and the valuation of retained noncontrolling equity investments when a subsidiary is deconsolidated. SFAS 160 also establishes disclosure requirements that clearly identify and distinguish between the interests of the parent and the interests of the noncontrolling owners. This statement is effective for the Company beginning January 1, 2009. The Company is assessing the impact of SFAS 160 on its future consolidated financial statements, particularly the minority interest related to Tooth Doctor.

In March 2008, the FASB issued FSP 157 and related interpretations that (1) partially deferred the effective date of SFAS No. 157 “Fair Value Measurement” for one year for certain nonfinancial assets and nonfinancial liabilities and (2) removed certain leasing transactions from the scope of SFAS No. 157. SFAS No. 157 as amended by this FSP is effective for nonfinancial assets and nonfinancial liabilities in fiscal years beginning after November 15, 2008 and will be applied prospectively. The provisions of SFAS No. 157 are not expected to have a material impact on our consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161, “ Disclosures about Derivative Instruments and Hedging Activities ” (“SFAS 161”). SFAS No. 161 amends and expands the disclosure requirements of SFAS No. 133, “ Accounting for Derivative Instruments and Hedging Activities, ” with the intent to provide users of financial statements with an enhanced understanding of how and why an entity uses derivative instruments, how these instruments and related hedged items are accounted for under SFAS No. 133 and how derivative instruments and related hedged items affect an entity’s financial position, financial performance and cash flow. To meet those objectives, this statement requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments and disclosures about credit-risk-related contingent features in derivative agreements. This statement is effective for the Company beginning January 1, 2009. The Company is assessing the impact of SFAS 161 on its future consolidated financial statements.

Other new pronouncements issued by the FASB that are not effective until after December 31, 2008 are not expected to have a material impact on our consolidated financial statements, financial position, results of operations or liquidity or are not relevant to the Company are not included above.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the ordinary course of business, we are exposed to interest rate risk. With regard to our revolving credit facility, we are also exposed to variable rate interest for the banks’ applicable margins ranging from 4.25% to 4.5% based upon our debt coverage ratio. For fixed rate debt, interest rate changes affect the fair value but do not impact earnings or cash flow. Conversely, for floating rate debt, interest rate changes generally do not affect the fair market value but do impact future earnings and cash flow. We do not believe a one percentage point change in interest rates would have a material impact on the fair market value of our fixed rate debt. In addition, we have entered into an interest rate swap arrangement to fix the interest rate on $20,000,000 of our long term debt borrowings. The pre-tax earnings and cash flow impact for one year, based upon the amounts outstanding at December 31, 2008 under our variable rate revolving credit facility and term loan, for each one percentage point change in interest rates would be approximately $1,111,000 per annum.

Management’s Report on Internal Control Over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) promulgated under the Securities Exchange Act of 1934, as amended. As required by Rule 13a-15(c) under the Exchange Act, the Company’s management evaluated the effectiveness of the design and operation of its internal control over financial reporting based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that evaluation, the Company’s management concluded that the Company’s internal control over financial reporting as of December 31, 2008 was effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2008 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of American Dental Partners, Inc.

In our opinion, the accompanying consolidated financial statements in the accompanying index present fairly, in all material respects, the financial position of American Dental Partners, Inc. (the “Company”) at December 31, 2008 and December 31, 2007, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2008 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing in Item 8. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note 1 to the consolidated financial statements, the Company is in the process of pursuing financial arrangements based on the fact that the outstanding term loan and revolving credit facility mature on January 20, 2010.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

For the Years Ended December 31, 2008, 2007 and 2006

(1) Description of Business

American Dental Partners, Inc. (the “Company”) is a leading provider of dental facilities, support staff and business services to multidisciplinary dental group practices in selected markets throughout the United States. The Company customarily acquires selected assets of the dental practices with which it affiliates and enters into long-term service agreements with professional corporations, professional associations or service corporations which are not owned by the Company. The Company is responsible for providing all services necessary for the administration of the non-clinical aspects of the dental operations, while the affiliated dental practices are responsible for providing dental care to patients. Services provided to the affiliated practices include providing assistance with organizational planning and development; recruiting, retention and training programs; quality assurance initiatives; facilities development and management; employee benefits administration; procurement; information systems and practice technology; marketing and payor relations; and financial planning, reporting and analysis. The Company operates in one segment.

The Company’s revolving credit facility and term loan mature on January 20, 2010 and the current credit markets are very limited and restrictive. If the Company fails to extend the maturity or to refinance its revolving credit facility and term loan with its existing lenders or others on satisfactory terms it would likely have a material adverse effect on its business, financial condition and results of operations. The Company may be able to refinance only a portion of its revolving credit facility and term loan, necessitating the issuance of subordinated debt, preferred stock or common stock, or some combination of such securities. Such securities may include interest or dividends, voting rights or other dilutive effects to our existing shareholders (see Note 8, “Debt” for further discussion).

(2) Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and include the accounts of American Dental Partners, Inc., its wholly-owned subsidiaries and its Arizona’s Tooth Doctor for Kids (“Tooth Doctor”) subsidiary which is owned 85% by the Company. All material intercompany balances and transactions have been eliminated in consolidation. Management has determined that, based on the provisions of its service agreements, the Company is not required to consolidate the financial statements of the affiliated practices which are affiliated with the Company by means of a long-term service agreement with its own.

Use of Estimates

The preparation of these consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The Company’s carrying amount of accounts receivable, net, requires management to make estimates and assumptions regarding the collectability of accounts receivable in its consolidated financial statements. The Company’s affiliation and acquisition transactions typically result in goodwill and other intangible assets, which affect the amount of future period amortization expense and possible impairment expense that the Company will incur. The determination of the value of such intangible assets requires management to make estimates and assumptions that affect the consolidated financial statements. The Company and the affiliated practices maintain insurance coverage for various business activities. Certain of the coverages have retentions which require the Company to make estimates and assumptions regarding losses below applicable retention levels. There can be no assurance that actual results will not differ from those estimates.

For the Years Ended December 31, 2008, 2007 and 2006

(2) Summary of Significant Accounting Policies – (Continued)

Reclassifications

Amounts due to affiliated practices of $566,000 for 2006 have been reclassified from accounts receivable, net to accounts payable to conform to 2008 and 2007 presentations. Professional fees associated with the litigation among PDG, P.A. (“PDG”), PDHC, Ltd. (“PDHC”) and the Company of $1,570,000 for 2006 have been reclassified from general corporate expense to litigation expense to conform to 2008 and 2007 presentations.

Cash and Cash Equivalents

The Company considers all highly liquid instruments with an original maturity of three months or less to be cash equivalents.

Fair Value of Financial Instruments

The Company believes the carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value because of the short-term nature of these items. The carrying amount of long-term debt approximates fair value because the interest rates are approximate rates at which similar types of borrowing arrangements could be obtained by the Company.

Net Revenue

The Company’s net revenue represents primarily reimbursement of expenses and fees charged to affiliated practices pursuant to the terms of the service agreements. Under certain service agreements, the Company’s service fee consists of a monthly fee which is based upon a specified percentage of the amount by which the affiliated practice’s patient revenue exceeds expenses. Under certain service agreements, the Company’s service fee consists entirely of a fixed monthly fee determined by agreement of the Company and the affiliated practice in a formal planning process. In all instances, the service fee is negotiated as fair market value for services and capital provided by the Company to the affiliated practices. Additionally, the Company’s net revenue includes amounts from patient revenue of Tooth Doctor, dental benefits third party administrator (“TPA”) fees and dental laboratory fees.

The Company’s net revenue from the reimbursement of expenses is accounted for on an accrual basis and is recognized when these expenses are incurred and billed to the affiliated practices. Reimbursement of expenses includes costs incurred by the Company for the operation and administration of the dental facilities that include salaries and benefits for non-dentist personnel working at the dental facilities; lab fees, dental supplies, office occupancy costs of the dental facilities, depreciation related to the fixed assets at the dental facilities and other expenses such as professional fees, marketing costs and general and administrative expenses.

In December 2007, the Company entered into a settlement agreement in which the service agreement with PDG, P.A. (“PDG”) was terminated effective December 31, 2007 and transferred the operating assets of 25 of the 31 Park Dental facilities and the “Park Dental” trade name to PDG. The Company also entered into a transition services agreement with PDG to provide interim management services for a period of nine months through September 30, 2008 for $19,000,000. In 2008, the Company concluded the transition services agreement with PDG and recorded fees as other revenue pursuant to the transition services agreement.

Inventories

Inventories consist primarily of dental supplies and are stated at the lower of cost or market, with cost being determined under the weighted average method.

For the Years Ended December 31, 2008, 2007 and 2006

(2) Summary of Significant Accounting Policies – (Continued)

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization are recorded using the straight-line method over the estimated useful lives of the related assets which are 30-40 years for buildings, 3-12 years for equipment, and 5-7 years for furniture and fixtures, and the remaining life of the lease for leasehold improvements. Development costs incurred for computer software development or obtained for internal use are capitalized and amortized in accordance with Statement of Position No. 98-1, “Accounting for the Costs of Computer Software Developed for Internal Use.” Capitalized software costs are amortized over 10 years once a determination is made that the software is deemed fit for operational use.

Goodwill and Other Intangible Assets

The Company has intangible assets, including goodwill and other identifiable intangibles assets, which are the result of affiliation transactions and acquisitions of businesses. The initial identification and valuation of these intangible assets and the determination of useful lives at the time of affiliation or acquisition involve the use of management judgments and estimates. These estimates are based on, among other factors, reviews of projected future income, cash flows and statutory regulations. At December 31, 2008, intangible assets were $252,000,000 and represented 71% of our total assets, and goodwill and indefinite-lived intangible assets represented 30% of our intangible assets and definite-lived intangible assets related to service agreements represented 70% of the Company’s intangible assets.

To the extent any intangible assets is impaired, its carrying value will be written down to its implied fair value and a charge will be made to earnings. Such an impairment charge could materially and adversely affect the Company’s operating results and financial condition.

Goodwill results from the excess of the purchase price of an acquisition over the estimated fair value of the tangible and intangible assets acquired and liabilities assumed. The Company performs an annual impairment assessment and compares the fair value to the carrying value of each reporting unit based on discounted future cash flows using a discount rate reflecting the Company’s average cost of funds. If impairment were determined, an appropriate adjustment to goodwill to reduce the asset’s carrying value would be made. The Company has not recorded any impairment charges on goodwill as of December 31, 2008.

The Company’s affiliations with dental group practices by means of service agreements are not business combinations, and as such, do not result in recognition of goodwill. The Company recognizes capitalized service agreement costs which are accounted for as definite-lived intangible assets acquired in other than a business combination and recorded at fair value. In determining the fair value of a service agreement recognized in connection with an affiliation, management estimates the timing, amount and value of future expected cash flows. These service agreements have contractual terms of 40 years but the asset is generally amortized on a straight-line basis over a period of 25 years. In the event a service agreement is terminated, the related affiliated practice is required, at the Company’s option in nearly all instances, to purchase the remaining unamortized balance of intangible assets at the current book value.

For the Years Ended December 31, 2008, 2007 and 2006

(2) Summary of Significant Accounting Policies – (Continued)

Customer relationship intangible assets associated with the acquisition of dental laboratories are amortized on a straight-line basis over 15 years. Customer relationship intangible assets associated with the acquisition of Tooth Doctor are amortized over five years on an accelerated basis. The trade name intangible asset associated with acquisition of Metro Dentalcare is amortized on a straight-line basis over five years. The trade name intangible asset associated with the Tooth Doctor acquisition is indefinite-lived and not amortized.

Management performs an impairment test on definite-lived intangible assets when facts and circumstances exist which would suggest that the intangible assets may be impaired by comparing the undiscounted net cash flows of the asset to its carrying value. If impairment were determined, an appropriate adjustment to the intangible asset would be made to reduce the asset’s carrying value to fair value. Fair value is determined by calculating the projected discounted operating net cash flows of the asset using a discount rate reflecting the Company’s average cost of funds. The Company has not recorded any impairment charges or write-downs on definite-lived intangibles as of December 31, 2008.

Insurance

The Company maintains various insurance coverages for its business, including property-casualty, business interruption, workers’ compensation and general liability, among others. In addition, the affiliated practices are required to maintain, or cause to be maintained, professional liability insurance with the Company as a named insured. Certain of the Company’s insurances are reinsured by a wholly-owned captive insurance company licensed in the state of Vermont. Several of these insurance programs have retention levels in which the Company and its captive insurance company are financially obligated for insured losses below certain financial thresholds before the insurer is financially obligated for insured losses. The Company and its captive insurance company maintain reserves for certain of these programs, which are based upon estimates provided by third-party actuaries or by individual case-basis valuations. Amounts accrued for workers compensation insurance, including estimates for losses below retention levels, were $1,600,000 for 2008 and $1,400,000 for 2007. Changes in trends of loss severity or loss frequency may affect the calculation of these estimates and create the need for subsequent adjustments to estimated loss reserves.

Fair Value Measurement

In September 2006, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”) which is effective for fiscal years beginning after November 15, 2007. This statement defines fair value, establishes a framework for measuring fair value and expands the related disclosure requirements. This statement applies under other accounting pronouncements that require or permit fair value measurements. The statement indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. Relative to SFAS 157, the FASB issued FASB Staff Positions (“FSP”) 157-1 and 157-2. FSP 157-1 amends SFAS 157 to exclude SFAS 13, “Accounting for Leases” (“SFAS 13”) and its related interpretive accounting pronouncements that address leasing transactions, while FSP 157-2 delays the effective date of the application of SFAS 157 to fiscal years beginning after November 15, 2008 for all nonfinancial assets and nonfinancial liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis. The Company adopted SFAS 157 as of January 1, 2008, with the exception of the application of the statement to non-recurring nonfinancial assets and nonfinancial liabilities.

For the Years Ended December 31, 2008, 2007 and 2006

(2) Summary of Significant Accounting Policies – (Continued)

The Company uses the market approach technique to value its financial instruments and there were no changes in valuation techniques during 2008. The Company’s financial assets and liabilities are primarily comprised of cash equivalents and an interest rate swap.

SFAS 157 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs that are not corroborated by market data based on assumptions of the Company used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following table provides the assets and liabilities carried at fair value measured on a recurring basis as of December 31, 2008:


	Level 1		Level 2			Level 3		Total
Interest rate swap	$	-	$	(2,059	)	$	-	$	(2,059	)
Cash equivalents		4,105		-			-		4,105

Total	$	4,105	$	(2,059	)	$	-	$	2,046

In accordance with SFAS No. 107, “ Disclosures about Fair Value of Financial Instruments ”, the Company is required to disclose the fair value of its long-term debt at least annually or more frequently if the fair value has changed significantly.

The Company’s long-term debt is carried at cost and is more fully described in Note 8. As of December 31, 2008 the estimated fair value the Company’s revolving line of credit was $31,188,000 and the fair value of the term loan was $102,015,000.

Income Taxes

Deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory rates applicable to future years to differences between the consolidated financial statement carrying amounts and the tax basis of existing assets and liabilities, as well as from net operating loss and tax credit carry forwards. The Company evaluates the recoverability of these future tax deductions and credits by assessing the adequacy of future expected taxable income from all sources, including reversal of taxable temporary differences, forecasted operating earnings and available tax planning strategies. These sources of income inherently rely heavily on estimates. The Company uses its historical experience and its short and long-range business forecasts to provide insight. To the extent the Company does not consider it more likely than not that a deferred tax asset will be recovered, a valuation allowance is established.

Earnings per Share

Earnings per share are computed based on SFAS No. 128 “Earnings per Share.” SFAS No. 128 requires presentation of basic earnings per share (“Basic EPS”) and diluted earnings per share (“Diluted EPS”) by all

AMERICAN DENTAL PARTNERS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued)

(2) Summary of Significant Accounting Policies – (Continued)

entities that have publicly traded common stock or potential common stock (options, warrants, convertible securities or contingent stock arrangements). Basic EPS is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS gives effect to all dilutive potential common shares outstanding during the period. The computation of Diluted EPS does not assume conversion, exercise or contingent exercise of securities that would have an anti-dilutive effect on earnings.

Recent Accounting Pronouncements

In December, 2007, the FASB issued SFAS No. 141(R) “ Business Combinations ” (“SFAS 141(R)”). SFAS 141(R) introduces significant changes in the accounting for and reporting of business acquisitions. SFAS 141(R) continues the movement toward the greater use of fair values in financial reporting and increased transparency through expanded disclosures. SFAS 141(R) changes how business acquisitions are accounted for and will impact financial statements at the acquisition date and in subsequent periods. In addition, SFAS 141(R) will impact the annual goodwill impairment test associated with acquisitions that close both before and after its effective date. SFAS 141(R) applies prospectively to fiscal years, and interim periods within those fiscal years, beginning on or after December 15, 2008. An entity may not apply SFAS 141(R) before that date. The Company expects no material effect at adoption date. However, upon adoption, this statement may materially affect the accounting for any future business combinations.

In March 2008, the FASB issued FSP 157-1 and 157-2 that (1) partially deferred the effective date of SFAS No. 157 “Fair Value Measurement” for one year for certain nonfinancial assets and nonfinancial liabilities and (2) removed certain leasing transactions from the scope of SFAS No. 157. SFAS No. 157 as amended by this FSP is effective for nonfinancial assets and nonfinancial liabilities in fiscal years beginning after November 15, 2008 and will be applied prospectively. The provisions of SFAS No. 157 are not expected to have a material impact on our consolidated financial statements.

In March 2008, the FASB issued SFAS No. 161, “ Disclosures about Derivative Instruments and Hedging Activities ” (“SFAS 161”). SFAS No. 161 amends and expands the disclosure requirements of SFAS No. 133, “ Accounting for Derivative Instruments and Hedging Activities”, with the intent to provide users of financial statements with an enhanced understanding of how and why an entity uses derivative instruments, how these instruments and related hedged items are accounted for under SFAS No. 133 and how derivative instruments and related hedged items affect an entity’s financial position, financial performance and cash flow. To meet those objectives, this statement requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments and

The Company adopted the provisions of FIN 48 on January 1, 2008. There was no material impact on our results of operations or financial position as a result of the implementation of FASB Interpretation No. 48, “ Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement 109 ” (“FIN 48”). The amount of gross unrecognized tax benefits at December 31, 2008 was $386,000, of which $386,000 would impact the Company’s effective tax rate if recognized. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

It is expected that the amount of unrecognized tax benefits will change in the next twelve months; however, the Company does not expect the change to have a significant impact on the results of operations or the financial position of the Company.

The Company recognizes interest and penalties accrued in connection with unrecognized tax benefits as a component of income before taxes in the Consolidated Statements of Income, which is consistent with the recognition of these items in prior reporting periods. Accrued interest and penalties were $104,235 and $120,522 as of January 1, 2008 and December 31, 2008, respectively.

Revolving Line of Credit and Term Loan

The Company has a revolving credit facility in the amount of $75,000,000. The facility matures on January 20, 2010 and can be used for general corporate purposes, including working capital, acquisitions and affiliations and capital expenditures. Borrowings under the credit facility bear interest at either prime or LIBOR plus a margin, at the Company’s option. The margin is based upon the Company’s debt coverage ratio and ranges from 4.25% to 4.50% for both prime borrowings and LIBOR borrowings. At December 31, 2008, the LIBOR and prime interest rate under the credit facility, including borrowing margin, was 8.48%. In addition, the Company pays a commitment fee on the unused balance of its credit facility ranging from 0.375% to 0.5%. Borrowings are limited to an availability formula based on earnings before income taxes, depreciation and amortization, adjusted for certain items, and are collateralized by a first lien on substantially all of the Company’s assets, including a pledge of the stock of the Company’s subsidiaries. The Company is also required to comply with financial and other covenants, including minimum net worth, leverage and fixed charge coverage ratios and maximum capital expenditures as defined by the credit agreement. The Company was in compliance with its covenants as of December 31, 2008. The outstanding balance under this line as of December 31, 2008 was $31,100,000, and the Company had stand-by letters of credit amounting to $1,669,200 at December 31, 2008. The unused balance under this revolving credit facility as of December 31, 2008 was $42,230,800 and based on borrowing covenants, reduced by the stand-by letter of credit, $35,346,730 was available for borrowing.

The Company has a term loan in the amount of $100,000,000. The loan matures on January 20, 2010 and was used to fund the Company’s 2007 acquisitions and affiliations. Interest on the term loan is at LIBOR plus a margin of 4.5%. The margin for the first 90 days from October 24, 2008 is 450 basis points and will increase 50 basis points March 1, 2009 and each 90 days thereafter. All of the obligations under this term loan facility rank pari passu in right of payment to all of the obligations of the Company’s revolving credit facility.

Pursuant to amendments to both the revolving credit facility and term loan on October 24, 2008 the Company is permitted to borrow up to $15,000,000 annually for capital expenditures, $15,000,000 annually for acquisitions and up to $13,000,000 for earnout and contingent payments on previously completed acquisitions, subject to various financial covenants, including a maximum debt to earnings before interest, taxes, depreciation and amortization leverage ratio of 3.75x.

On May 9, 2007, the Company entered into an interest rate swap to hedge $20,000,000 of borrowings under the credit facility. Under this arrangement, the Company has effectively converted its 3-month, floating LIBOR interest rate exposure, plus a credit spread, to fixed 5.0%, plus a credit spread, until February 2012. Management believes it will maintain debt in amounts in excess of the hedge amount through its maturity.

In December 2007, the Company entered into a settlement agreement with respect to litigation among PDHC Ltd., (“PDHC”) one of its Minnesota subsidiaries, and PDG. Under the terms of the definitive agreements contemplated by the settlement agreement and in release of the PDG litigation, the Company transferred to PDG the leases and operating assets of 25 of the 31 Park Dental facilities and trade name “Park Dental” to PDG, effective February 29, 2008. The parties also entered into a transition services agreement. Under the agreement, the Company agreed to provide interim management services to PDG for a period of up to nine months commencing on January 1, 2008 for $19,000,000. PDG paid the interim management services fee and the Company provided the services. The parties are completing the final steps in the separation of PDHC and PDG.

In accordance with Statement of Financial Accounting Standards No. 5, “ Accounting for Contingencies ” (“SFAS 5”), the Company accrued a loss contingency of $30,968,000 at December 31, 2007, which was comprised of the following items: (i) $39,968,000 representing the estimated fair value, using discounted cash flows, of the operating assets being transferred and (ii) a reduction of $9,000,000 from the $19,000,000 to be paid by PDG, which represents the amount deemed in excess of the fair market value of the management services to be provided. In addition to this $30,968,000 accrual, litigation expense in the Company’s statement of operations is also comprised of the following: (i) $2,035,000 of accounts receivable due from PDG that the Company reserved as part of the litigation settlement and (ii) professional fees associated with the litigation of $3,731,000. Professional fees associated with the litigation of $1,570,000 for the year ended December 31, 2006 have been reclassified from general corporate expenses to litigation expense. The Company expensed, as interest expense, approximately $851,000 of previously capitalized financing costs pursuant to Emerging Issues Task Force Issue No. 98-14 “ Debtor’s Accounting for Changes in Line-of-Credit or Revolving-Debt Arrangements ” (“EITF 98-14”), when the Company and the lenders entered into a forbearance agreement on December 18, 2007.

On February 29, 2008, under the terms of the settlement agreement the Company transferred the operating assets of 25 of the 31 Park Dental facilities and pursuant to Financial Accounting Standards No. 144 “ Accounting for the Impairment or Disposal of Long-Lived Assets ” (“SFAS 144”) we realized a net gain of $30,763,000 which represents the fair value of the assets transferred in excess of the book value of the assets transferred. In addition, the Company recorded an interim management services fee, during 2008, totaling $10,000,000 offset by the costs to provide these services including severance costs.

the voting power of the holders of Common Stock and the issuance of which could be used by the Board of Directors in defense of a hostile takeover of the Company. As of December 31, 2008 and 2007, there were no shares of Preferred Stock issued or outstanding.

Common Stock

The Company is authorized to issue up to 25,000,000 shares of Common Stock, $0.01 par value. As of December 31, 2008, 13,484,241 shares were issued and 12,901,741 shares were outstanding. As of December 31, 2007, 13,397,120 shares were issued and 12,814,620 shares were outstanding.

Treasury Stock

On December 16, 1999, the Board of Directors authorized the Company to repurchase up to $5,000,000 of its Common Stock in the open market. Under this plan, the Company has repurchased 582,500 shares of its Common Stock through December 31, 2008 at a cost of $3,874,000.

(11) Stock-based Compensation

Options granted under the following plans generally have a ten-year term and generally have a vesting period of four years, except for the 2005 Directors Stock Option Plan which vests over three years . At December 31, 2008, options for 1,366,301 shares were vested and 588,125 shares were available for future grants under the 2005 Equity Incentive Plan and the 2005 Directors Stock Option Plan. The Company issues new shares upon stock option exercises. No restricted shares have been awarded.

Under SFAS No. 123(R), the Company is required to select a valuation technique or option-pricing model that meets the criteria as stated by the standard, which includes a binomial model and the Black-Scholes model. At the present time, the Company is using the Black-Scholes model. The adoption of SFAS No. 123(R), applying the “modified prospective method,” as elected by the Company, requires the Company to estimate forfeitures in calculating the expense related to stock-based compensation as opposed to only recognizing those forfeitures and the corresponding reduction in expense as they occur. The Company has chosen to use the “short-cut method” to determine the pool of windfall tax benefits as of the adoption of SFAS No. 123(R). In addition, SFAS No. 123(R) requires the Company to reflect tax savings resulting from the tax deductions in excess of expense as a financing cash flow in its statement of cash flows rather than as an operating cash flow as reflected prior to the adoption of SFAS No. 123(R).

The Company recognized stock-based compensation expense for options granted and its employee stock purchase plan (“ESPP”) of $1,978,000 and $1,898,000 for the years ended December 31, 2008 and 2007, respectively, and this expense was recorded within general corporate expense on the Company’s consolidated statements of income. In addition, the Company recorded a deferred tax benefit associated with stock-based compensation for options grants of $1,396,435 and $622,386 for the years ended December 31, 2008 and 2007, respectively, and no amounts were capitalized. The remaining unrecognized stock-based compensation expense for unvested stock option awards as of December 31, 2008 was approximately $4,006,000 and the weighted average period of time over which this cost will be recognized is 3 years.

(11) Stock-based Compensation – (Continued)

The fair value for these options and employee stock purchase rights granted was estimated at the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions for the years ended December 31:


	2008						2007						2006
	Stock Options			ESPP			Stock Options			ESPP			Stock Options			ESPP
Risk-free interest rate		2.7	%		1.6	%		4.6	%		5.1	%		4.6	%		4.9	%
Expected dividend yield		0.0	%		0.0	%		0.0	%		0.0	%		0.0	%		0.0	%
Expected volatility		77	%		71	%		42	%		39	%		42	%		41	%
Expected life (years)		5.40			0.25			6.20			0.50			6.25			0.50
Expected forfeiture		4.0	%		-			3.0	%		-			4.0	%		-
Weighted average fair value of options/ purchase rights granted during the year	$	6.31		$	1.95		$	10.60		$	6.13		$	6.91		$	4.59

The Company calculated the volatility assumption using a blend of a historical volatility rate for a period equal to the expected term and an expected volatility rate based on more recent activity. The Company estimated the expected life of its stock options using the simplified method for determining the expected term as prescribed by the Securities and Exchange Commission’s Staff Accounting Bulletin No. 107, “ Share-based Payment. ” Expected life of the Company’s ESPP purchase rights reflects the length of each period (six months) an employee can participate in at the end of which shares are purchased.

Since adoption of SFAS 123(R), forfeitures are estimated based on historical experience.

The following table summarizes the stock option transactions during the year ended December 31, 2008:
