OPERATING INFORMATION

Change in Auditor

On January 22, 2015, Grant Thornton LLP, or Grant Thornton, resigned as the Company’s independent registered public accounting firm. Grant Thornton’s resignation was accepted by the Company’s audit committee.

Grant Thornton’s audit reports on the Company’s consolidated financial statements for the period from December 19, 2013 to January 2, 2014 and for the period from December 19, 2013 to December 31, 2013 did not contain an adverse opinion or disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope or accounting principles.

Since the Company’s establishment in December 2013 and through the end of the fiscal year ended December 31, 2014 and the subsequent interim period from January 1, 2015 through January 22, 2015, (i) there were no disagreements between the Company and Grant Thornton on any matters of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Grant Thornton, would have caused Grant Thornton to make reference to the subject matter of the disagreement in its reports on the Company’s consolidated financial statements, and (ii) there were no “reportable events” as that term is defined in Item 304(a)(1)(v) of Regulation S-K.

The Company has provided Grant Thornton with a copy of the foregoing statements and has requested and received from Grant Thornton a letter addressed to the Securities and Exchange Commission stating that Grant Thornton agrees with the above statements.

The Company is presently in discussions with several accounting firms to replace Grant Thornton as its independent registered public accounting firm for the fiscal year ended December 31, 2014.
