New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-09 clarifying when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The new guidance will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. It does not change the accounting for modifications. The ASU is effective prospectively for reporting periods beginning after December 15, 2017, with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued. We do not expect the adoption of this ASU will have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04 simplifying the accounting for goodwill impairment for all entities. The new guidance eliminates the requirement to calculate the implied fair value of goodwill (Step 2 of the current two-step goodwill impairment test under ASC 350). Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value (Step 1 of the current two-step goodwill impairment test). The ASU is effective prospectively for reporting periods beginning after December 15, 2019, with early adoption permitted for annual and interim goodwill impairment testing dates after January 1, 2017. We are currently evaluating the impact of the new guidance on our goodwill impairment testing process and consolidated financial statements. In November 2016, the FASB issued ASU 2016-18 amending the presentation of restricted cash within the statement of cash flows. The new guidance requires that restricted cash be included within cash and cash equivalents on the statement of cash flows. The ASU is effective retrospectively for reporting periods beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of the new guidance and we do not expect it to have a material impact on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15 clarifying how entities should classify certain cash receipts and payments on the statement of cash flows. The new guidance addresses classification of cash flows related to the following transactions: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; 3) contingent consideration payments made after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies; 6) distributions received from equity method investees; and 7) beneficial interests in securitization transaction. ASU 2016-15 also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017 and requires retrospective application. Early adoption is permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU 2016-13 amending how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance requires the application of a current expected credit loss model which is a new impairment model based on expected losses. Under this model, an entity recognizes an allowance for expected credit losses based on historical experience, current conditions and forecasted information rather than the current methodology of delaying recognition of credit losses until it is probable a loss has been incurred. This ASU is effective for interim and annual reporting periods beginning after December 15, 2019 with early adoption permitted for annual reporting periods beginning after December 15, 2018. We are currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures. This ASU applies to trade accounts receivable and may have an impact on our calculation of the allowance for uncollectible accounts receivable. In March 2016, the FASB issued ASU 2016-09 amending several aspects of share-based payment accounting. This guidance requires all excess tax benefits and tax deficiencies to be recorded in the income statement when the awards vest or are settled, with prospective application required. The guidance also changes the classification of such tax benefits or tax deficiencies on the statement of cash flows from a financing activity to an operating activity, with retrospective or prospective application allowed. Additionally, the guidance requires the classification of employee taxes paid when an employer withholds shares for tax-withholding purposes as a financing activity on the statement of cash flows, with retrospective application required. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. Early adoption is permitted. We adopted this guidance effective January 2, 2017, and the adoption did not have a material effect on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02 amending the existing accounting standards for lease accounting and requiring lessees to recognize lease assets and lease liabilities for all leases with lease terms of more than 12 months, including those classified as operating leases. Both the asset and liability will initially be measured at the present value of the future minimum lease payments, with the asset being subject to adjustments such as initial direct costs. Consistent with current U.S. GAAP, the presentation of expenses and cash flows will depend primarily on the classification of the lease as either a finance or an operating lease. The new standard also requires additional quantitative and qualitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases in order to provide additional information about the nature of an organization’s leasing activities. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 and requires modified retrospective application. Early adoption is permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures. As our branch operations are primarily conducted in leased facilities, this ASU will likely have a material impact on our consolidated balance sheet, may have a material impact to our consolidated statement of earnings and will require us to disclose additional information about our leasing activities. We established a cross-functional implementation team to further assess the impact of the standard. In January 2016, the FASB issued ASU 2016-01 amending the current guidance for how entities measure certain equity investments, the accounting for financial liabilities under the fair value option, and the presentation and disclosure requirements relating to financial instruments. The new guidance requires entities to use fair value measurement for equity investments in unconsolidated entities, excluding equity method investments, and to recognize the changes in fair value in net income at the end of each reporting period. Under the new standard, for any financial liabilities in which the fair value option has been elected, the changes in fair value due to instrument-specific credit risk must be recognized separately in other comprehensive income. Presentation and disclosure requirements under the new guidance require public business entities to use the exit price when measuring the fair value of financial instruments measured at amortized cost. In addition, financial assets and liabilities must now be presented separately in the notes to the financial statements and grouped by measurement category and form of financial asset. This ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is only permitted for the financial liability provision. We are currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures. We expect to implement the standard with the modified retrospective method and the cumulative reclassification adjustment between other comprehensive income and retained earnings on the consolidated balance sheet is expected to be material. This standard will impact how we recognize changes in the fair value of our available-for-sale investment and could have a material impact on our consolidated financial statements. In May 2014, the FASB issued new revenue recognition guidance under ASU 2014-09 that will supersede the existing revenue recognition guidance under U.S. GAAP. The new standard focuses on creating a single source of revenue guidance for revenue arising from contracts with customers for all industries. The objective of the new standard is for companies to recognize revenue when it transfers the promised goods or services to its customers at an amount that represents what the company expects to be entitled to in exchange for those goods or services. In July 2015, the FASB deferred the effective date by one year (ASU 2015-14). This ASU will now be effective for annual periods, and interim periods within those annual periods, beginning on or after December 15, 2017. Since the issuance of the original standard, the FASB has issued several other subsequent updates including the following: 1) clarification of the implementation guidance on principal versus agent considerations (ASU 2016-08); 2) further guidance on identifying performance obligations in a contract as well as clarifications on the licensing implementation guidance (ASU 2016-10); 3) rescission of several SEC Staff Announcements that are codified in Topic 605 (ASU 2016-11); 4) additional guidance and practical expedients in response to identified implementation issues (ASU 2016-12); and 5) technical corrections and improvements (ASU 2016-20). The new standard will be effective for us beginning January 1, 2018. We established a cross-functional implementation team consisting of representatives from across our business segments and various departments. We utilized a bottom-up approach to analyze the impact of the standard on our various revenue streams by reviewing our current contracts with customers, accounting policies and business practices to identify potential differences that would result from applying the requirements of the new standard. In addition, we identified, and are in the process of implementing, appropriate changes to our business processes, systems and controls to support recognition and disclosure under the new standard. We have been closely monitoring FASB activity related to the new standard to conclude on specific interpretive issues. During 2016 and 2017, we have made significant progress toward completing our evaluation of the potential impact that adopting the new standard will have on our consolidated financial statements. Based on our preliminary analysis, revenue from our temporary staffing contracts and substantially all of our other contracts with customers will continue to be recognized over time as services are rendered. The primary impact of adopting ASU 2014-09 is anticipated to be the deferral of contract costs. Additionally, we anticipate expanded disclosures around the nature, amount, timing and uncertainty of revenue and cash flows arising from our contracts with customers. We will continue to evaluate the impact of this guidance on our consolidated financial statements, disclosures and internal controls. Our preliminary assessments are subject to change. We expect to implement the standard with the modified retrospective approach beginning January 1, 2018, which recognizes the cumulative effect of application recognized on that date. Management has evaluated other recently issued accounting pronouncements and does not believe that any of these pronouncements will have a significant impact on our consolidated financial statements and related disclosures.
