General Motors Co. has not met several significant goals it planned to achieve by year-end, including workforce reductions and the sale of failing brands.

Chief Executive Fritz Henderson on Wednesday outlined progress made by GM in the 90 days since it emerged from bankruptcy protection. While GM has made strides in several key areas, the auto maker has fallen short in others.

Henderson said GM is on track to meet cash flow and cost reduction targets, though he didn't elaborate. GM will release financial results for the third quarter in mid-November, he said.

Also on schedule are plans to shrink GM's U.S. dealership network and eliminate four money-losing brands.

The company has reduced North American production to what Henderson said is an acceptable level, and has picked up market share on a global basis. GM's global market share rose slightly in the third quarter compared with the first half of this year, he said, though the figure is still below last year.

However, GM failed to meet employee reduction targets for its U.S. workforce. The company has about 10,000 more U.S. workers than it planned to have by the end of 2009 after buyout programs for hourly and salaried programs fell short. GM aimed to have 64,000 workers.

The auto maker missed a Sept. 30 goal of finalizing a deal to sell the Hummer truck brand to a Chinese manufacturer. Henderson said GM has made "further progress" on completing that sale.

A plan to sell Saturn to auto retailer Penske Automotive Group (PAG) fell through after Penske failed to find a manufacturer to build the vehicles once GM stopped, though Henderson said the development won't hurt GM's restructuring plans.

GM also is racing to complete the sale of a majority stake in its Opel European unit to a consortium let by Canadian parts maker Magna International Inc. (MGA, MG.A.T). Henderson said Magna and GM remain in concessionary talks with European labor groups.

Meantime, the company's sales have suffered in the global sales slump, and GM lost 2 percentage points of market share in the critical U.S. market. Henderson said the company's market share remains slightly ahead of the conservative estimates the company made early this year when laying out its restructuring plan.

Separately, Henderson announced that Mark LaNeve, GM's sales chief and longtime executive, is leaving for a job at a different company. LaNeve headed sales and marketing until Henderson restructured the management team and put former product head Bob Lutz in charge of marketing.

"We are knocking some of these things off and staying focused on getting the rest of these matters behind us before the end of the year," Henderson said on a conference call with analysts and reporters. "We are quite confident we will come out of this with a competitive cost structure."

Henderson faces intense pressure from GM's new chairman and the U.S. government - the company's new majority owner - to stem the sales slide and improve GM's financial performance.

The move to publicize its restructuring moves contrast with the more buttoned-up strategy of Chrysler Group LLC.

Chrysler, which also reorganized in bankruptcy court and like GM is partly owned by the U.S. government, has said little about its recovery efforts.

However, Chrysler CEO Sergio Marchionne on Wednesday said he will publicly release details of his five-year survival plan for the company on Nov. 4. The briefing, to be held at Chrysler's headquarters in Auburn Hills, Mich., will outline product plans and the new image focus for the Chrysler, Jeep and Dodge brands.
