Changes in Registrant's Certifying Accountant. On June 2, 2005, Barrett Business Services, Inc. ("BBSI"), dismissed its previous independent accountants, PricewaterhouseCoopers LLP ("PwC"), and engaged Moss Adams LLP ("Moss Adams") as BBSI's new principal independent registered public accounting firm to audit its financial statements. The Audit Committee of BBSI's Board of Directors directed the review process and made the final decision to dismiss PwC and engage Moss Adams. The reports of PwC on BBSI's financial statements for the fiscal years ended December 31, 2004 and 2003 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2003 and 2004, and the subsequent interim period through June 2, 2005, BBSI had no disagreement with PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of PwC, would have caused PwC to make reference to the subject matter of the disagreement in connection with its report on BBSI's financial statements for such fiscal years, other than a matter relating to BBSI's financial statements for the fiscal year ended December 31, 2004. This issue related to the effect of an accounting principle on the reporting of assets and liabilities relating to workers' compensation claims that are insured by BBSI's prior excess workers' compensation insurance carrier, and was resolved to PwC's satisfaction by BBSI's presentation of its accrued liabilities for certain insured workers' compensation claims on a gross basis on its balance sheets, along with a corresponding receivable from its insurer. The Audit Committee discussed this issue with BBSI's management and with PwC. It is BBSI's management's view that, in analyzing whether the application of a longstanding accounting principle required a change in the presentation of workers' compensation liabilities and receivables on BBSI's balance sheets, its initial viewpoint differed from that of PwC, following which BBSI acceded to PwC's conclusions. BBSI's decision to engage new independent accountants to audit its financial statements did not result directly from this issue. During the period from January 1, 2003 through June 2, 2005, no "reportable events," as described in Item 304(a)(1)(v) of Regulation S-K promulgated by the Securities and Exchange Commission, occurred with respect to BBSI. BBSI has authorized PwC to respond fully to the inquiries of Moss Adams concerning the matters described above. BBSI is providing PwC with a copy of this Form 8-K concurrent with filing the report with the Securities and Exchange Commission, accompanied by BBSI's request that PwC furnish it with a letter addressed to the Securities and Exchange Commission stating whether PwC agrees with the above statements. BBSI will file a copy of PwC's letter under cover of an amendment to this Form 8-K within two business days following receipt from PwC. During the period from January 1, 2003 through June 2, 2005, BBSI did not consult with Moss Adams regarding (1) the application of accounting principles to a specified transaction, whether completed or proposed, (2) the type of audit opinion that might be rendered with respect to BBSI's financial statements or (3) any matter that was either the subject of a "disagreement" or a "reportable event" (as such terms are defined in Items 304(a)(1)(iv) and (v) of Regulation S-K). Item 9.01. Financial Statements and Exhibits. 16.1 Letter from PricewaterhouseCoopers LLP to the Securities and Exchange Commission stating its agreement with the statements made in this report (to be filed by amendment). SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
