1. Basis of Presentation.

The accompanying condensed consolidated financial statements are unaudited and have been prepared by MPS Group, Inc. (‘MPS’ or the ‘Company’) in accordance with the rules and regulations of the Securities and Exchange Commission (‘SEC’). Accordingly, certain information and footnote disclosures usually found in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. The financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Form 10-K for the year ended December 31, 2004.

The accompanying condensed consolidated financial statements reflect all adjustments (including normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the financial position and results of operations for the interim periods presented. The results of operations for an interim period are not necessarily indicative of the results of operations for a full fiscal year.

Stock-Based Compensation

The Company accounts for its employee and director stock option plans in accordance with Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees (“APB Opinion No. 25”), and related interpretations. The Company measures compensation expense for employee and director stock options as the aggregate difference between the fair value of its common stock and exercise prices of the options on the date that both the number of shares the grantee is entitled to receive and the exercise prices are known. Compensation expense associated with restricted stock grants is equal to the fair value of the shares on the date of grant and is recorded pro rata over the required holding period. If the Company had elected to recognize compensation cost for all outstanding options granted by the Company by applying the fair value recognition provisions of Statement of Financial Accounting Standards (‘SFAS’) No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure, to stock-based employee compensation, net income and earnings per share would have been reduced to the pro forma amounts indicated below.
