1. Basis of Presentation

The accompanying condensed consolidated financial statements are unaudited and have been prepared by MPS Group, Inc. (“MPS”, “we”, “us”, or “our”) 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 our Form 10-K for the year ended December 31, 2006.

The accompanying condensed consolidated financial statements reflect all adjustments (including normal recurring adjustments) which, in our opinion, 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.

Short Term Investments

At June 30, 2007, our short term investments were comprised of auction rate securities. We classify these investments as available-for-sale securities and in accordance with Statement of Financial Accounting Standards (“SFAS”) 115, Accounting for Certain Investments in Debt and Equity Securities, we record these securities at fair value in Current Assets on our Condensed Consolidated Balance Sheets. In addition, we report changes in the fair value of these securities, if any, as unrealized holding gains and losses, net of the related tax effect, as a separate component of other comprehensive income until realized.

New Accounting Pronouncements

In September 2006, the Financial Accounting Standards Board (“FASB”) issued SFAS 157, Fair Value Measurements, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 does not require any new fair value measurements, but rather clarifies the application of other accounting pronouncements that require or permit fair value measurements. The provisions of SFAS 157 are effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those years. Earlier application is encouraged, provided the reporting entity has not yet issued financial statements for that fiscal year. While we are currently evaluating the impact of SFAS 157, we do not currently expect the adoption of SFAS 157 to have a material effect on our consolidated financial statements.

In February 2007, the FASB issued SFAS 159, The Fair Value Option for Financial Assets and Financial Liabilities. This standard permits entities to choose to measure many financial instruments and certain other items at fair value and is effective for the first fiscal year beginning after November 15, 2007. While we are currently evaluating the impact of SFAS 159, we do not currently expect the adoption of SFAS 159 to have a material effect on our consolidated financial statements.

2. Share-Based Compensation

During the three months ended June 30, 2007, we granted approximately 1.7 million shares of restricted stock with a weighted average fair value at grant of $14.21 to non-employee directors, executives, and certain other employees. The restricted stock granted vests over four to seven years.

3. Income Taxes

We adopted FASB Interpretation No. (“FIN”) 48 Accounting for Uncertainty in Income Taxes, on January 1, 2007. FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Additionally, FIN 48 provides guidance on recognition, classification, and disclosure of tax positions. Upon adoption of FIN 48, we reduced our reserve for uncertain tax positions by $1.2 million and recorded this reduction as an adjustment to the opening balance of Retained earnings on our Condensed Consolidated Balance Sheets. At January 1, 2007, our unrecognized tax benefits – that is, the aggregate tax effect of differences between tax return positions and the benefits recognized in our financial statements – were $10.5 million. If recognized, $6.9 million of our unrecognized tax benefits would impact our Provision for income taxes on our Condensed Consolidated Statements of Operations and thus our effective tax rate.

During the second quarter of 2007, we settled a state income tax audit. We recorded a $257,000 tax benefit and reduced our gross unrecognized tax benefit by $3.3 million as a result of this settlement.

We classify interest on uncertain tax positions as interest expense, and we classify income tax penalties as a component of income tax expense. Prior to the adoption of FIN 48, both interest and penalties were accrued as a component of income tax expense. At January 1, 2007, before any tax benefits, our accrued interest on unrecognized tax benefits was $6.2 million and related accrued penalties were $130,000.

In the second quarter of 2007, we accrued approximately $188,000 of additional interest expense and reversed approximately $1,021,000 of accrued interest for the settlement of the above referenced state income tax audit. Accrued interest is in Accounts payable and accrued expenses on our Condensed Consolidated Balance Sheets at June 30, 2007.

We are subject to periodic review by federal, foreign, state and local taxing authorities in the ordinary course of business. With few exceptions, we are no longer subject to examination by these taxing authorities for years prior to 2002. Currently, we have no outstanding income tax audits with the Internal Revenue Service. Our federal income tax returns have been audited or surveyed by the Internal Revenue Service through 2002. Many of our UK subsidiaries have been audited through 2003. HM Revenue and Customs is currently conducting an income tax audit of our UK subsidiaries for 2004. Lastly, we generally have several state income tax audits throughout the year since we operate in a multi-state environment. We do not expect our unrecognized tax benefits to change significantly over the next 12 months.
