accounting principles to a specified transaction, either completed or proposed,
or the type of audit opinion that might be rendered on the Company's financial
statements and neither a written report was provided to the Company nor oral
advice was provided that PwC concluded was an important factor considered by the
Company in reaching a decision as to the accounting, auditing, or financial
reporting issue; or (ii) any matter that was either the subject of a
disagreement, as that term is defined in Item 304(a)(1)(iv) of Regulation S-K
and the related instructions to Item 304 of Regulation S-K, or a reportable
