<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><I>Portfolio Manager Compensation Overview </I></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The discussion below describes the portfolio managers&#146; compensation as of December&nbsp;31, 2019 for Messrs. Accettella, Kim and
McClements and as of April&nbsp;30, 2020 for Mr.&nbsp;Menge. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Advisor&#146;s financial arrangements with its portfolio managers, its
competitive compensation and its career path emphasis at all levels reflect the value senior management places on key resources. Compensation may include a variety of components and may vary from year to year based on a number of factors. The
principal components of compensation include a base salary, a performance-based discretionary bonus, participation in various benefits programs and one or more of the incentive compensation programs established by the Advisor. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Base Compensation.</B>&nbsp;Generally, portfolio managers receive base compensation based on their position with the firm. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Generally, discretionary incentive compensation for Active Equity portfolio managers is based on
a formulaic compensation program. The Advisor&#146;s formulaic portfolio manager compensation program is based on team revenue <FONT STYLE="white-space:nowrap">and&nbsp;pre-tax&nbsp;investment</FONT> performance relative to appropriate competitors
or benchmarks <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">over&nbsp;1-,&nbsp;3-&nbsp;and&nbsp;5-year&nbsp;performance</FONT></FONT></FONT> periods, as applicable. In most cases, these benchmarks
are the same as the benchmark or benchmarks against which the performance of the funds or other accounts managed by the portfolio managers are measured. The Advisor&#146;s Chief Investment Officers determine the benchmarks or rankings against which
the performance of funds and other accounts managed by each portfolio management team is compared and the period of time over which performance is evaluated. With respect to these portfolio managers, such benchmarks for the Trust and other accounts
are: BST Opt Overwriting Strategy Composite Index; MSCI All Country World Information Technology- Net Return in USD. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">A smaller element of
portfolio manager discretionary compensation may include consideration of: financial results, expense control, profit margins, strategic planning and implementation, quality of client service, market share, corporate reputation, capital allocation,
compliance and risk control, leadership, technology and innovation. These factors are considered collectively by the management of the Advisor and the relevant Chief Investment Officers. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Discretionary Incentive Compensation &#150; Messrs. Accettella and McClements </B></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Discretionary incentive compensation is a function of several components: the performance of the Advisor, Inc., the performance of the
portfolio manager&#146;s group within the Advisor, the investment performance, including risk-adjusted returns, of the firm&#146;s assets or strategies under management or supervision by that portfolio manager, and/or the individual&#146;s
performance and contribution to the overall performance of these portfolios and the Advisor. Among other things, the Advisor&#146;s Chief Investment Officers make a subjective determination with respect to each portfolio manager&#146;s compensation
based on the performance of the funds, other accounts or strategies managed by each portfolio manager. Performance is generally measured on <FONT STYLE="white-space:nowrap">a&nbsp;pre-tax&nbsp;basis</FONT> over various time periods <FONT
STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">including&nbsp;1-,&nbsp;3-&nbsp;and&nbsp;5-&nbsp;year</FONT></FONT></FONT> periods, as applicable. The performance of some funds, other accounts or
strategies may not be measured against a specific benchmark. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B>Distribution of Discretionary Incentive
Compensation.</B>&nbsp;Discretionary incentive compensation is distributed to portfolio managers in a combination of cash, deferred BlackRock, Inc. stock awards, and/or deferred cash awards that notionally track the return of certain Advisor
investment products. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Portfolio managers receive their annual discretionary incentive compensation in the form of cash. Portfolio managers
whose total compensation is above a specified threshold also receive deferred BlackRock, Inc. stock awards annually as part of their discretionary incentive compensation. Paying a portion of discretionary incentive compensation in the form of
deferred BlackRock, Inc. stock puts compensation earned by a portfolio manager for a given year &#147;at risk&#148; based on the Advisor&#146;s ability to sustain and improve its performance over future periods. In some cases, additional deferred
BlackRock, Inc. stock may be granted to certain key employees as part of a long-term incentive award to aid in retention, align interests with long-term shareholders and motivate performance. Deferred BlackRock, Inc. stock awards are generally
granted in the form of BlackRock, Inc. restricted stock units that vest pursuant to the terms of the applicable plan and, once vested, settle in BlackRock, Inc. common stock. The portfolio managers of the Trust have deferred BlackRock, Inc. stock
awards. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For certain portfolio managers, a portion of the discretionary incentive compensation is also distributed in the form of deferred
cash awards that notionally track the returns of select investment products of the Advisor they manage, which provides direct alignment of portfolio manager discretionary incentive compensation with investment product results. Deferred cash awards
vest ratably over a number of years and, once vested, settle in the form of cash. Only portfolio managers who manage specified products and whose total compensation is above a specified threshold are eligible to participate in the deferred cash
award program. </P>

Stock Purchase Plan (ESPP). The employer contribution components of the RSP include a company match equal to 50% of the first 8% of eligible pay contributed to the plan capped at $5,000 per year, and a company retirement contribution equal <FONT

investment funds managed by the firm. BlackRock, Inc. contributions follow the investment direction set by participants for their own contributions or, absent participant investment direction, are invested into a target date fund that corresponds
to, or is closest to, the year in which the participant attains age 65. The ESPP allows for investment in BlackRock, Inc. common stock at a 5% discount on the fair market value of the stock on the purchase date. Annual participation in the ESPP is
limited to the purchase of 1,000 shares of common stock or a dollar value of $25,000 based on its fair market value on the purchase date. All of the eligible portfolio managers are eligible to participate in these plans. </P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Advisor has built a professional working environment, firm-wide compliance culture and compliance procedures and systems designed to
protect against potential incentives that may favor one account over another. The Advisor has adopted policies and procedures that address the allocation of investment opportunities, execution of portfolio transactions, personal trading by employees
and other potential conflicts of interest that are designed to ensure that all client accounts are treated equitably over time. Nevertheless, the Advisor furnishes investment management and advisory services to numerous clients in addition to the
Trust, and the Advisor may, consistent with applicable law, make investment recommendations to other clients or accounts (including accounts which are hedge funds or have performance or higher fees paid to the Advisor, or in which portfolio managers
have a personal interest in the receipt of such fees), which may be the same as or different from those made to the Trust. In addition, BlackRock, Inc., its affiliates and significant shareholders and any officer, director, shareholder or employee
may or may not have an interest in the securities whose purchase and sale the Advisor recommends to the Trust. BlackRock, Inc., or any of its affiliates or significant shareholders, or any officer, director, shareholder, employee or any member of
their families may take different actions than those recommended to the Trust by the Advisor with respect to the same securities. Moreover, the Advisor may refrain from rendering any advice or services concerning securities of companies of which any
of BlackRock, Inc.&#146;s (or its affiliates&#146; or significant shareholders&#146;) officers, directors or employees are directors or officers, or companies as to which BlackRock, Inc. or any of its affiliates or significant shareholders or the
officers, directors and employees of any of them has any substantial economic interest or possesses material <FONT STYLE="white-space:nowrap">non-public</FONT> information. </P>

Certain portfolio managers also may manage accounts whose investment strategies may at times be opposed to the strategy utilized for a fund. It should also be noted that Messrs.&nbsp;Kim and
Menge may be managing hedge fund and/or long only accounts, or may be part of a team managing hedge fund and/or long only accounts, subject to incentive fees. Messrs.&nbsp;Kim and Menge may therefore be entitled to receive a portion of any incentive
fees earned on such accounts. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As a fiduciary, the Advisor owes a duty of loyalty to its clients and must treat each client fairly. When
the Advisor purchases or sells securities for more than one account, the trades must be allocated in a manner consistent with its fiduciary duties. The Advisor attempts to allocate investments in a fair and equitable manner among client accounts,
with no account receiving preferential treatment. To this end, BlackRock, Inc. has adopted policies that are intended to ensure reasonable efficiency in client transactions and provide the Advisor with sufficient flexibility to allocate investments
in a manner that is consistent with the particular investment discipline and client base, as appropriate. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="center"><B>Investors should retain this
