(ii)             The reports of PricewaterhouseCoopers LLP on the financial statements for the fiscal years ended December 31, 2018 and 2017 contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle.

(iv)          During the fiscal years ended December 31, 2018 and 2017 and the subsequent interim period through October 21, 2019, there were no disagreements with PricewaterhouseCoopers LLP 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 PricewaterhouseCoopers LLP would have caused them to make reference thereto in their reports on the financial statements for such years.
