Item 4.

Ownership.

TCA acts as an investment adviser to certain investment companies registered under the Investment Company Act of 1940. 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 owners 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. TCA also acts as an investment adviser to certain managed accounts. Under contractual

agreements with these managed account clients, TCA, with respect to the securities held in these client accounts, has voting and/or investment power with respect to these client

accounts. 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 investment and voting 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 that are held by its clients.
