The Fund adopted a Managed Distribution Plan (the “Plan”) in 2007 to maintain its current 6.5 cent per share distribution rate. Under the Plan, the Fund will distribute all available investment income to its shareholders, consistent with the Fund’s primary objective. If and when sufficient investment income is not available on a monthly basis, the Fund will distribute long-term capital gains and/or return of capital to its shareholders in order to maintain the 6.5 cent per share distribution level. The Fund previously provided this estimate of the sources of the May 2025 distributions:
