Accounting Standards Update	2. Accounting Standards Update In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606), which outlines a comprehensive new revenue recognition model designed 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 new standard also requires additional quantitative and qualitative disclosures. The Company plans to adopt the new standard beginning January 1, 2018 and expects to use the modified retrospective approach. The allowance for fallouts (permanent placement candidates that do not remain with the client through the contingency period, which is typically 90 days or less) is currently included in accounts receivable allowances. Under the new standard these are considered contract liabilities and upon adoption of the standard they will be presented as liabilities on the Company’s consolidated balance sheet. Based on the Company’s analysis to date, the adoption of this standard is not expected to have a material impact on its consolidated financial statements and disclosures. In May 2017, the FASB issued ASU No, 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting. An entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The amendments in this ASU will be applied prospectively to awards modified on or after the adoption date. The Company is required to adopt the new standard on January 1, 2018, and early adoption is permitted. The Company does not expect the adoption of this standard will have a material impact on its consolidated financial statements.
