be filed within the prescribed time period. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Registrant is unable to file its Form N-CSR for the period ended February 29, 2016
without unreasonable effort or expense because additional time is needed to address an issue that has arisen concerning the independence of the Registrant&#146;s auditor, PricewaterhouseCoopers LLP (&#147;PwC&#148;), and, therefore, the accuracy of
the statement in PwC&#146;s report included in Item 1 of <FONT STYLE="white-space:nowrap">Form&nbsp;N-CSR</FONT> regarding PwC being an independent registered public accounting firm. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On May 4, 2016, PwC advised the Registrant&#146;s Audit Committee that it is in discussions with the Staff of the Securities and Exchange
Commission (&#147;SEC&#148;) regarding a difference in the interpretation and application of Rule 2-01(c)(1)(ii)(A) of <FONT STYLE="white-space:nowrap">Regulation&nbsp;S-X</FONT> (the &#147;Loan Rule&#148;), the rule related to debtor-creditor
relationships involving an auditor under Regulation S-X&#146;s Qualifications of Accountants provisions. The issue relates solely to the identification of PwC as an independent registered public accounting firm in its report attached to the
Registrant&#146;s shareholder report and not the information in the shareholder report itself. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">PwC has advised the Audit Committee that
it believes it is independent and it continues to have discussions with the SEC&#146;s Staff to resolve this interpretive matter. PwC further advised the Audit Committee that this matter did not compromise or impair its objectivity with respect to
conducting its audits and issuing its reports on the financial statements of the Registrant. While PwC represented to the Audit Committee that it feels confident that PwC&#146;s interpretation of the Loan Rule is correct, neither PwC nor the Audit
Committee can be certain of the final outcome. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="center">(Attach extra Sheets if Needed) </P>
