During the Fund’s two most recent fiscal years (ended November 30, 2016 and November 30, 2015) and the subsequent interim period through August 14, 2017, there were no disagreements between the Fund and KPMG on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of KPMG, would have caused it to make reference to the subject matter of the disagreements in its reports on the financial statements of the Fund for such years.

During the Fund’s two most recent fiscal years (ended November 30, 2016 and November 30, 2015) and the subsequent interim period through August 14, 2017, there were no “reportable events” (as defined in Item 304(a)(l)(v) of Regulation S-K under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)).
