GENERAL INSTRUCTIONS
1. | Submission of this Report. Effective January 31, 2017, a registered public accounting firm must use this Form to file with the Board reports required by Rule 3211 and to file any amendments to such reports. Unless otherwise directed by the Board, the registered public accounting firm must file this Form electronically with the Board through the Board's Web-based system. |
2. | Defined Terms. The definitions in the Board's rules apply to this Form. Italicized terms in the instructions to this Form are defined in the Board's rules. In addition, as used in the instructions to this Form, the term "the Firm" means the registered public accounting firm that is filing this Form with the Board; and the term, "other accounting firm" means (i) a registered public accounting firm other than the Firm; or (ii) any other person or entity that opines on the compliance of any entity's financial statements with an applicable financial reporting framework. |
3. | When this Report is Considered Filed. A report on Form AP is considered filed on the date the Firm submits to the Board a Form AP in accordance with Rule 3211 that includes the certification required by Part VI of Form AP. Note 1: A Form AP filing is not required for an audit report of a registered public accounting firm that is referred to by the Firm in accordance with AS 1205, Part of the Audit Performed by Other Independent Auditors. Note 2: Rule 3211 requires the filing of a report on Form AP regarding an audit report only the first time the audit report is included in a document filed with the Commission. Subsequent inclusion of precisely the same audit report in other documents filed with the Commission does not give rise to a requirement to file another Form AP. In the event of any change to the audit report, including any change in the dating of the report, Rule 3211 requires the filing of a new Form AP the first time the revised audit report is included in a document filed with the Commission. |
4. | Amendments to this Report. Amendments to Form AP are required to correct information that was incorrect at the time the Form was filed or to provide information that was omitted from the Form and was required to be provided at the time the Form was filed. When filing a Form AP to amend an earlier filed Form AP, the Firm must supply not only the corrected or supplemental information, but it must include in the amended Form AP all information and certifications that were required to be included in the original Form AP. The Firm may access the originally filed Form AP through the Board's Web-based system and make the appropriate amendments without needing to re-enter all other information. Note: The Board will designate an amendment to a report on Form APas a report on "Form AP/A." |
5. | Rules Governing this Report. In addition to these instructions, Rules 3210 and 3211 govern this Form. Read these rules and the instructions carefully before completing this Form. |
6. | Language. Information submitted as part of this Form must be in the English language. |
7. | Partner ID. For purposes of responding to Item 3.1.a.6, the Firm must assign each engagement partner that is responsible for the Firm's issuance of an issuer audit report a 10-digit Partner ID number. The Firm must assign a unique Partner ID number to each such engagement partner and must use the same Partner ID for that engagement partner in every Form AP filed by the Firm that identifies that engagement partner. The Partner ID must begin with the Firm ID—a unique five-digit identifier based on the number assigned to the Firm by the PCAOB—and be followed by a unique series of five digits assigned by the Firm. When an engagement partner is no longer associated with the Firm, his/her Partner ID must be retired and not reassigned. If the engagement partner was previously associated with a different registered public accounting firm and had a Partner ID at that previous firm, the Firm must assign a new Partner ID in accordance with the instructions above. The new Firm must report, in Item 3.1.a.6, the new Partner ID and all Partner IDs previously associated with the engagement partner. Note: The Firm ID can be found by viewing the firm's summary page on the PCAOB website, where it is displayed parenthetically next to the name of the firm—firm name (XXXXX). For firms that have PCAOB-assigned identifiers with fewer than 5 digits, leading zeroes should be added before the number to make 5 digits, e.g., 99 should be presented as 00099. |

In responding to Part IV, if the financial statements for the most recent period and one or more other periods covered by the audit report identified in Item 3.1.a.4 were audited during a single audit engagement (for example, in a reaudit of a prior period(s)), the calculation should be based on the percentage of audit hours attributed to such firms in relation to the total audit hours for the periods identified in Item 3.1.c.
