Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Condensed Consolidated Financial Statements (Unaudited) of PRGX Global, Inc. and its wholly owned subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions for the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain reclassifications have been made to the Company's consolidated financial statements for the fiscal year 2017 to conform to the fiscal year 2018 presentation. Operating results for the three and nine-month periods ended September 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. Except as otherwise indicated or unless the context otherwise requires, “PRGX,” “we,” “us,” “our” and the “Company” refer to PRGX Global, Inc. and its subsidiaries. For further information, refer to the Consolidated Financial Statements and the related Notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, except for the Company’s revenue recognition policy which has been revised as a result of the implementation of a new standard effective January 1, 2018. Significant Accounting Policies Revenue Recognition The Company has revised its accounting policy as it relates to the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, and the subsequent amendments and modifications thereto. The revised policy requires the Company to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To adhere to this core principle, the Company applies the following five steps: (a) identify contract(s) with a customer; (b) identify the performance obligations in a contract; (c) determine the transaction price; (d) allocate the transaction price to the performance obligations in a contract; and (e) recognize revenue when (or as) performance obligations are satisfied. The Company determines that the performance obligations have been satisfied when its customers obtain control of the goods or services as evidenced by the customer’s ability to direct the use, or the ability to receive substantially all of the remaining economic benefit, of the contract assets. Additionally, for purposes of determining the appropriate timing of recognition, revenue will be recognized over time or at a point in time based on an evaluation of the specific criteria that is to be achieved to meet the performance obligations of each contract. The determination that the core principle for revenue recognition has been met, and the five steps have been applied appropriately, requires significant judgment. Management considers the application of this judgment to be critical in determining the appropriate amount of revenue to be recognized. The most critical judgments are required in the determination of the transaction price, the identification of the performance obligations within a contract, and the determination as to whether or not and to what extent such performance obligations have been satisfied. A misapplication of this judgment could result in inappropriate recognition of revenue. Revenue is recognized over time, on an invoice basis for the Company's recovery audit contracts, which is approximately 96% of consolidated revenue for the nine-month period ended September 30, 2018. The Company has adopted the Invoicing Expedient as provided for in FASB Accounting Standards Codification ("ASC") Topic 606, which allows for the recognition of revenue for an amount that an entity has a right to invoice its customer. It is management’s conclusion that the Company's right to consideration from its customers corresponds directly to the value provided to customers from its performance to-date, as represented by billable recoveries. A recovery is billable when it is determined that the customer has received the economic benefit from the service (generally through credits taken against existing accounts payable due to, or refund checks received from, the customer’s vendors). The manner in which a claim is recovered by a client often is dictated by industry practice. Many clients establish specific procedural guidelines that must be satisfied prior to submitting claims for client approval, and these guidelines are unique to each client. On occasion, it is possible that a transaction has met the core principle for revenue recognition, but the Company does not recognize revenue until the customary business practices and processes specific to that client have been completed. Historically, there has been a certain amount of recovery audit revenue with respect to which, even though the Company has met the requirements of its revenue recognition policy, its clients’ vendors ultimately have rejected the claims underlying the revenue. In that case, the Company's clients may request a refund or offset of such amount even though the fees may have been previously collected. The Company records any such refunds as a reduction of revenue. The Company provides refund liabilities for these reductions in the economic value previously received by its clients with respect to vendor claims that have been identified and for which revenue has been previously recognized. The Company computes an estimate of its refund liabilities at any given time based on actual historical refund data. Revenue is recognized over time for the Company's subscription services. Typically, implementation services, hosting services, unspecified upgrades, technical and support services, service level guarantees and subscription rights under contracts for subscription services are delivered concurrently and are therefore considered a single performance obligation. Generally, revenue will be recognized ratably over the subscription term as this represents the timing of when those services are transferred to the customer. The subscription term commences when the customer both has access to the software application and can benefit from its use. Revenue is recognized at a point in time for certain services provided on a fixed fee basis and over time for certain services performed on a fee per unit of time-basis or other unit of performance. The revenue recognition method is determined based on the specific criteria that is to be achieved to meet the performance obligations of each transaction within a contract. When a contract includes an option to acquire future goods or services that constitutes a material right to the customer, and those goods or services are similar to the original goods and services provided for in the contract, the Company has adopted the Practical Alternative as prescribed in ASC Topic 606 to estimate the standalone selling price of that option. Billed receivables are stated at the amount expected to be collected and do not bear interest. The Company makes ongoing estimates relating to the collectability of billed receivables and maintains a reserve for estimated losses resulting from the inability of its clients to meet its financial obligations to the Company. This reserve is primarily based on the level of past-due accounts based on the contractual terms of the receivables; the Company's history of write-offs; and its relationships with, and the economic status of, its clients. Unbilled receivables relate to claims for which the Company's customers have received economic value and for which they acknowledge that the unbilled receivable has been earned but has not yet been billed. The Company typically invoices the customer in the subsequent month. The Company includes unbilled receivables and refund liabilities in determining revenue. Contract assets will be recorded if a performance obligation is satisfied (and revenue recognized), but the Company is not entitled to payment until other conditions as specified in the contract are met. Contract liabilities are recognized when consideration is received and the Company has not yet transferred the goods or services to the customer. The Company refers to this as deferred revenue. The Company derives a relatively small portion of revenue on a fee-for-service basis whereby billing is based upon a fixed fee, a fee per unit of time, or a fee per other unit of service. The Company recognizes revenue for these types of services when the core principles for revenue recognition have been met. Impact of Recently Issued Accounting Standards A summary of the new accounting standards issued by the FASB and included in the ASC that apply to PRGX is included below: Adopted by the Company in Fiscal Year 2018 FASB ASC Update No. 2014-09 - In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), as later amended, which resulted in a new accounting standard Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. The new revenue recognition standard requires entities to recognize revenue in a way that depicts 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. ASU 2014-09 has replaced most existing revenue recognition guidance within GAAP. The new standard became effective for the Company on January 1, 2018 and was adopted by the Company on that date. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements utilizing the modified retrospective approach. FASB ASU No. 2018-07 - In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718)-Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. The Company has elected early adoption of this standard, which is permitted, and adopted this standard on September 30, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. FASB ASU No. 2018-03 - In February 2018, the FASB issued ASU No. 2018-03, Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10), which clarified certain aspects of the previously issued ASU 2016-01 issued in January 2016. This standard updates ASU guidance on the classification and measurement of financial instruments, including significant revisions in accounting related to the classification and measurement of investments in equity securities and presentation of certain fair value changes for financial liabilities when the fair value option is elected. This ASU requires equity securities to be measured at fair value with changes in fair value recognized through net earnings and amends certain disclosure requirements associated with the fair value of financial instruments. In the period of adoption, the Company is required to reclassify the unrealized gains/losses on equity securities within accumulated other comprehensive income (loss) to retained earnings. This standard became effective for the Company on September 30, 2018 and was adopted by the Company on that date. The adoption of this standard did not have a material impact on the Company's consolidated financial statements. Accounting Standards Not Yet Adopted FASB ASU 2018-13 - In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820)): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements. The new guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Upon the effective date, certain provisions are to be applied prospectively, while others are to be applied retrospectively to all periods presented. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. We are currently evaluating the effect of this standard on our consolidated financial statement disclosures. Since this standard affects disclosure requirements only, it is not expected to have an impact on the Company's consolidated financial statements. FASB ASU No. 2016-02 - In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This standard requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition. This standard requires lessors to classify leases as either sales-type, finance or operating. A sales-type lease occurs if the lessor transfers all of the risks and rewards, as well as control of the underlying asset, to the lessee. If risks and rewards are conveyed without the transfer of control, the lease is treated as a financing lease. If the lessor does not convey risks and rewards or control, an operating lease results. ASU 2016-02 was subsequently amended by FASB ASU No. 2018-10 - Codification Improvements to Topic 842, Leases, which was issued in July 2018 to increase stakeholders' awareness of the amendments and to expedite the improvements. ASU 2018-11, Leases (Topic 842)-Target Improvements was issued July 2018, which provides an additional transition method which allows entities to initially apply this standard on the date of adoption, which will be January 1, 2019 for the Company, and recognize a cumulative-effect adjustment to the opening balance sheet on that date. This standard will become effective for the Company in the first quarter of 2019. The Company is working towards establishing policies and implementing necessary changes to data and processes to be able to comply with the new requirements. The Company has acquired a software solution to manage and account for leases under the new standard and has completed its review of existing leases and embedded lease arrangements. The Company expects the adoption of this standard to increase lease assets and lease liabilities by approximately $10 million. The adoption of this standard is not expected to have a material impact on the Company's net income or its cash flows.
