The source of the funds used to acquire the Common Shares reported herein is the working capital of the Funds and margin borrowings described in the following sentence. Such Common Shares are held by the Reporting Persons in commingled margin accounts, which may extend margin credit to the Reporting Persons from time to time, subject to applicable federal margin regulations, stock exchange rules and credit policies. In such instances, the positions held in the margin account are pledged as collateral security for the repayment of debit balances in the account. The margin accounts bear interest at a rate based upon the broker’s call rate from time to time in effect. Because other securities are held in the margin accounts, it is not possible to determine the amounts, if any, of margin used to purchase the Common Shares reported herein.
