 and losses included in realized and unrealized gains and losses are included in, or are a reduction of, ordinary income for federal income tax purposes. Distributions:Distributions to shareholders are recorded on each ex-dividenddate. The Fund declared and paid or reinvested dividends quarterly under an income-based distribution policy. The income-based distribution policy has a stated goal of providing quarterly distributions out of the Fund’s accumulated undistributed net investment income and/or other sources subject to the requirements of the 1940 Act and Subchapter M of the Internal Revenue Code (the “Code”). The source for the dividend can come from net investment income and net realized capital gains measured on a fiscal year basis. Any portion of the distribution that exceeds income and capital gains will be treated as a return of capital. Under certain conditions, U.S. federal tax regulations cause some or all of the return of capital to be taxed as ordinary income. Income and capital gain distributions are determined in accordance with income tax regulations which may differ from GAAP. These differences may be primarily due to differing treatments for market discount and premium, losses recognized on structured debt, losses deferred due to wash sales, foreign currency gains and losses, and spillover distributions. Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to paid-incapital and may affect net investment income per share. Derivative Instruments:Derivatives are financial instruments which are valued based on the values of one or more indicators, such as a security, asset, currency, interest rate, or index. Derivative transactions can create investment leverage and may be highly volatile. A derivative contract may result in a mark-to-marketloss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. It is possible that a derivative transaction will result in a loss greater than the principal amount invested. The Fund may not be able to close out a derivative transaction at a favorable time or price. 34
