 Advisor is not required to devote its full time to the business of the
Acquiring Fund and there is no guarantee or requirement that any investment professional or other employee of the Investment Advisor will allocate a substantial portion of his or her time to the Acquiring Fund. The loss of one or more individuals
involved with the Investment Advisor could have a material adverse effect on the performance or the continued operation of the Acquiring Fund.

Reliance on Service Providers Risk.The Acquiring Fund must rely upon the performance of service providers to perform
certain functions, which may include functions that are integral to the Acquiring Fund’s operations and financial performance. Failure by any service provider to carry out its obligations to the Acquiring

Fund in accordance with the terms of its appointment, to exercise due care and skill or to perform its obligations to the Acquiring Fund at all as a result of insolvency, bankruptcy or other
causes could have a material adverse effect on the Acquiring Fund’s performance and returns to common shareholders. The termination of the Acquiring Fund’s relationship with any service provider, or any delay in appointing a replacement
for such service provider, could materially disrupt the business of the Acquiring Fund and could have a material adverse effect on the Acquiring Fund’s performance and returns to common shareholders.

Information Technology Systems Risk.The Acquiring Fund is dependent on the Investment Advisor for certain management
services as well as back-office functions. The Investment Advisor depends on information technology systems in order to assess investment opportunities, strategies and markets and to monitor and control risks for the Acquiring Fund. It is possible
that a failure of some kind which causes disruptions to these information technology systems could materially limit the Investment Advisor’s ability to adequately assess and adjust investments, formulate strategies and provide adequate risk
control. Any such information technology-related difficulty could harm the performance of the Acquiring Fund. Further, failure of the back-office functions of the Investment Advisor to process trades in a timely fashion could prejudice the
investment performance of the Acquiring Fund.

Cyber Security Risk.With the increased use of technologies such as
the Internet to conduct business, the Acquiring Fund is susceptible to operational, information security and related risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber-attacks include, but are not
limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational
