TCA is an investment adviser in accordance with Rule 13d-1(b)(1)(ii)(E) and TORIX is an investment company registered under Section 8 of the Investment Company Act 1940 (15 U.S.C. 80a-8).

 
Item 4. Ownership.

TCA acts as an investment advisor to certain investment companies registered under the Investment Company Act of 1940, including TORIX. TCA, by virtue of investment advisory
agreements with these investment companies, has all investment and voting power over securities owned of record by these investment companies. However, despite their delegation
of investment and voting power to TCA, these investment companies may be deemed to be the beneficial owner under Rule 13d-3 of the Act, of the securities they own of record
because they have the right to acquire investment and voting power through termination of their investment advisory agreement with TCA. Thus, TCA has reported that it shares
voting power and dispositive power over the securities owned of record by these investment companies, and TORIX has reported that it shares voting power and dispositive power
over the securities owned of record by it. TCA also acts as an investment advisor to certain managed accounts. Under contractual agreements with these managed account clients,
TCA has voting and/or investment power. TCA has reported that it shares voting and/or investment power over the securities held by these client managed accounts despite a
delegation of voting and/or investment power to TCA because the clients have the right to acquire voting and/or investment power through termination of their agreements with TCA.
TCA may be deemed the beneficial owner of the securities covered by this statement under Rule 13d-3 of the Act.
