• 6 FRA, BGT, DSU, HYT, BLW, BHK, BIT, BTZ, and EGF (the "Funds") have adopted a level distribution plan (the "Plan") and employ a managed distribution to support a level distribution of income, capital gains and/or return of capital. The fixed amount distributed per share is subject to change at the

discretion of the Fund's Board of Directors. Shareholders should not draw any conclusions about the Fund's investment performance from the amount of the Fund's current distributions or from the terms of the Plan.

The Funds may estimate that they have distributed more than their income and net realized capital gains in the current fiscal year; therefore, a portion of the distribution may be a return of capital. A return of capital may occur, for example, when some or all of a shareholder's investment is paid back to the shareholder. A return of capital distribution does not necessarily reflect the Fund's investment performance and should not be confused with 'yield' or 'income'. When distributions exceed total

return performance, the difference will reduce the Fund's net asset value per share.

Although the character of income will not be determined until the end of the fund's fiscal year, below are Fund's that have a portion of their distribution classified as return of capital fiscal year to date:

EGF's distribution fiscal year to date is comprised of 25% return of capital as of 12/31/2020

BIT's distribution fiscal year to date is comprised of 44% return of capital as of 12/31/2020

FRA's distribution fiscal year to date is comprised of 24% return of capital as of 12/31/2020

BGT's distribution fiscal year to date is comprised of 24% return of capital as of 12/31/2020

DSU's distribution fiscal year to date is comprised of 22% return of capital as of 12/31/2020

Fund will distribute long-term capital gains and/or return capital to its stockholders in order to maintain a level distribution. The Fund is currently not relying on any exemptive relief from

Section 19(b) of the 1940 Act. The Fund expects that distributions under the Plan will exceed current income and capital gains and therefore will likely include a return of capital.
