17 C.F.R. § 229.304
(a)
(1) If during the registrant's two most recent fiscal years or any subsequent interim period, an independent accountant who was previously engaged as the principal accountant to audit the registrant's financial statements, or an independent accountant who was previously engaged to audit a significant subsidiary and on whom the principal accountant expressed reliance in its report, has resigned (or indicated it has declined to stand for re-election after the completion of the current audit) or was dismissed, then the registrant shall:
(iii) State whether the decision to change accountants was recommended or approved by:
(v) Provide the information required by paragraph (a)(1)(iv) of this Item for each of the kinds of events (even though the registrant and the former accountant did not express a difference of opinion regarding the event) listed in paragraphs (a)(1)(v) (A) through (D) of this section, that occurred within the registrant's two most recent fiscal years and any subsequent interim period preceding the former accountant's resignation, declination to stand for re-election, or dismissal (“reportable events”). If the event led to a disagreement or difference of opinion, then the event should be reported as a disagreement under paragraph (a)(1)(iv) and need not be repeated under this paragraph.
(C) (1) The accountant's having advised the registrant of the need to expand significantly the scope of its audit, or that information has come to the accountant's attention during the time period covered by Item 304(a)(1)(iv), that if further investigated may:
(i) Materially impact the fairness or reliability of either: a previously issued audit report or the underlying financial statements; or the financial statements issued or to be issued covering the fiscal period(s) subsequent to the date of the most recent financial statements covered by an audit report (including information that may prevent it from rendering an unqualified audit report on those financial statements), or
(ii) Cause it to be unwilling to rely on management's representations or be associated with the registrant's financial statements, and
(2) Due to the accountant's resignation (due to audit scope limitations or otherwise) or dismissal, or for any other reason, the accountant did not so expand the scope of its audit or conduct such further investigation; or
(D) (1) The accountant's having advised the registrant that information has come to the accountant's attention that it has concluded materially impacts the fairness or reliability of either (i) a previously issued audit report or the underlying financial statements, or (ii) the financial statements issued or to be issued covering the fiscal period(s) subsequent to the date of the most recent financial statements covered by an audit report (including information that, unless resolved to the accountant's satisfaction, would prevent it from rendering an unqualified audit report on those financial statements), and
(2) Due to the accountant's resignation, dismissal or declination to stand for re-election, or for any other reason, the issue has not been resolved to the accountant's satisfaction prior to its resignation, dismissal or declination to stand for re-election.
(2) If during the registrant's two most recent fiscal years or any subsequent interim period, a new independent accountant has been engaged as either the principal accountant to audit the registrant's financial statements, or as an independent accountant to audit a significant subsidiary and on whom the principal accountant is expected to express reliance in its report, then the registrant shall identify the newly engaged accountant and indicate the date of such accountant's engagement. In addition, if during the registrant's two most recent fiscal years, and any subsequent interim period prior to engaging that accountant, the registrant (or someone on its behalf) consulted the newly engaged accountant regarding:
(ii) Any matter that was either the subject of a disagreement (as defined in paragraph 304(a)(1)(iv) and the related instructions to this item) or a reportable event (as described in paragraph 304(a)(1)(v)), then the registrant shall:
(3) Such transactions or events were material and were accounted for or disclosed in a manner different from that which the former accountants apparently would have concluded was required, the registrant shall state the existence and nature of the disagreement or reportable event and also state the effect on the financial statements if the method had been followed which the former accountants apparently would have concluded was required.
These disclosures need not be made if the method asserted by the former accountants ceases to be generally accepted because of authoritative standards or interpretations subsequently issued.
Instructions to Item 304: 1. The disclosure called for by paragraph (a) of this Item need not be provided if it has been previously reported as that term is defined in Rule 12b-2 under the Exchange Act (§ 240.12b-2 of this chapter); the disclosure called for by paragraph (a) must be provided, however, notwithstanding prior disclosure, if required pursuant to Item 9 of Schedule 14A (§ 240.14a-101 of this chapter). The disclosure called for by paragraph (b) of this section must be furnished, where required, notwithstanding any prior disclosure about accountant changes or disagreements. 2. When disclosure is required by paragraph (a) of this section in an annual report to security holders pursuant to Rule 14a-3 (§ 240.14a-3 of this chapter) or Rule 14c-3 (§ 240.14c-3 of this chapter), or in a proxy or information statement filed pursuant to the requirements of Schedule 14A or 14C (§ 240.14a-101 or § 240.14c-101 of this chapter), in lieu of a letter pursuant to paragraph (a)(2)(D) or (a)(3), prior to filing such materials with or furnishing such materials to the Commission, the registrant shall furnish the disclosure required by paragraph (a) of this section to any former accountant engaged by the registrant during the period set forth in paragraph (a) of this section and to the newly engaged accountant. If any such accountant believes that the statements made in response to paragraph (a) of this section are incorrect or incomplete, it may present its views in a brief statement, ordinarily expected not to exceed 200 words, to be included in the annual report or proxy or information statement. This statement shall be submitted to the registrant within ten business days of the date the accountant receives the registrant's disclosure. Further, unless the written views of the newly engaged accountant required to be filed as an exhibit by paragraph (a)(2)(B) of this Item 304 have been previously filed with the Commission the registrant shall file a Form 8-K concurrently with the annual report or proxy or information statement for the purpose of filing the written views as exhibits thereto. 3. The information required by Item 304(a) need not be provided for a company being acquired by the registrant that is not subject to the filing requirements of either section 13(a) or 15(d) of the Exchange Act, or, because of section 12(i) of the Exchange Act, has not furnished an annual report to security holders pursuant to Rule 14a-3 or Rule 14c-3 for its latest fiscal year. 4. The term “disagreements” as used in this Item shall be interpreted broadly, to include any difference of opinion concerning any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which (if not resolved to the satisfaction of the former accountant) would have caused it to make reference to the subject matter of the disagreement in connection with its report. It is not necessary for there to have been an argument to have had a disagreement, merely a difference of opinion. For purposes of this Item, however, the term disagreements does not include initial differences of opinion based on incomplete facts or preliminary information that were later resolved to the former accountant's satisfaction by, and providing the registrant and the accountant do not continue to have a difference of opinion upon, obtaining additional relevant facts or information. 5. In determining whether any disagreement or reportable event has occurred, an oral communication from the engagement partner or another person responsible for rendering the accounting firm's opinion (or their designee) will generally suffice as the accountant advising the registrant of a reportable event or as a statement of a disagreement at the “decision-making level” within the accounting firm and require disclosure under this Item.
