	Summary of Significant Accounting Policies
	Use of Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts disclosed in the financial statements and accompanying notes. Estimates, by their nature, are based on judgment and available information. Actual results could differ materially from those estimates.
	Significant estimates inherent in the preparation of the accompanying consolidated financial statements include the assumptions used in the determination of the allowance for doubtful accounts receivable, impairment assessment of goodwill, determination of the recoverability of long-lived assets, assessment of legal contingencies and calculation of income taxes.
	Reclassifications - For comparative purposes, certain amounts have been reclassified to conform to the current period presentation.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09 (Topic 606) Revenue from Contracts with Customers (ASU 2014-09). ASU 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific revenue guidance in addition to some cost guidance. ASU 2014-09 establishes a five-step model under the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance is effective for the Company beginning January 1, 2017 and the Company may apply this guidance using either a full retrospective approach, subject to certain practical expedients, or a modified retrospective approach with a cumulative effect adjustment as of the date of initial application. Early adoption is not permitted. The Company is evaluating the impact that adoption of this guidance will have on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (ASU 2014-12). The amendments in ASU 2014-12 require that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. ASU 2014-12 is effective for the Company beginning January 1, 2016 and the Company may apply the amendments either prospectively to all awards granted or modified after the effective date; or retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. Early adoption is permitted. The Company does not anticipate that the adoption of this guidance will have a material impact on its consolidated financial statements.

	Fair Value Disclosures
	The Company maintains a non-qualified Deferred Compensation Plan for highly compensated employees. The assets of the plan are held in the name of CDI at a third-party financial institution. Separate accounts are maintained for each participant to reflect the amounts deferred by the participant and all earnings and losses on those deferred amounts. The assets of the plan are held in publicly traded mutual funds. The fair value of the plan assets is calculated using the market price of the mutual funds as of the end of the period.
	The following tables summarize the assets and liabilities measured at fair value on a recurring basis by level of the fair value hierarchy for the indicated periods:

	The Company performed its annual assessment for impairment of goodwill and other indefinite-lived intangible assets as of July 1, 2013 and determined there was no impairment. The Company's assessment determined that the fair values for each of the Company's reporting units, with the exception of PSS EMEA, comprised primarily of the CDI AndersElite Limited business, were substantially in excess of their related carrying values as of July 1, 2013. The PSS EMEA reporting unit had a fair value in excess of its carrying value of 15% and goodwill of $10.5 million. The Company believes it has made reasonable estimates and assumptions to calculate the fair value of its reporting units and indefinite-lived intangible assets. If actual future results are not consistent with management's estimates and assumptions, the Company may have to take an impairment charge in the future related to its goodwill and other indefinite-lived intangible assets. There were no triggering events subsequent to July 1, 2013 that required additional testing for any reporting units or indefinite-lived intangible assets.

	Restructuring and Other Related Costs
	In December 2013, the Company announced that it would undertake a corporate restructuring in the first quarter of 2014 (the “2013 Restructuring Plan”) to improve operational effectiveness and further optimize the Company's cost structure. The 2013 Restructuring Plan included a workforce reduction and the consolidation of facilities and was substantially completed by June 30, 2014. The majority of the payments are expected to be made during 2014 with certain payments related to the consolidation of facilities expected through 2019. During the three months ended June 30, 2014, the Company adjusted its total restructuring liability due to lower than expected severance costs.
	The following table summarizes the provision, activity and balances related to the Restructuring Plan by cost type for the indicated periods:

Income Taxes	'
	Income Taxes
	The Company calculates an effective income tax rate each quarter using the estimated annual effective rate method based upon forecasted annual income by jurisdiction, statutory tax rates and other tax-related items. The impact of discrete items is recognized in the interim period in which they occur. Discrete items and the mix of domestic and foreign pre-tax income and losses with no tax benefit may significantly impact the interim period income tax provision and increase the volatility of the interim period effective tax rate at low levels of pre-tax income.
	The effective tax rates for the three months ended June 30, 2014 and 2013 were 36.4% and 32.5%, respectively. The effective tax rates for the six months ended June 30, 2014 and 2013 were 44.0% and 39.8%, respectively. During the six months ended June 30, 2014, the Company recorded a $0.5 million charge for the write-off of deferred tax assets related to the forfeiture of the outstanding equity awards due to the separation of the Company's former CEO.

GETS provides these solutions through a delivery model consisting of: centers of excellence, with concentrated skill sets required for larger, more complex projects; regional centers to service local needs of customers; customer-centered offices to deliver site-specific services; and a near-shore center to leverage low-cost design resources.
	•	Professional Staffing Services (PSS) - PSS provides skilled technical and professional personnel to its customers for discrete periods of time to augment the customer's workforce in times of project, seasonal, peak period or business cycle needs. These engagements can range from several months to multiple years in duration. PSS also provides permanent placement services.
