During such fiscal year- ends and through December 12, 2019, the date of dismissal, (i) there were no disagreements with 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 them to make reference to the subject matter of the disagreements in connection with their reports on the Funds' financial statements for such period, and (ii) there were no "reportable events" of the kind described in Item 304(a)(1)(v) of Regulation S-K under the Securities Exchange Act of 1934, as amended.
