Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying condensed consolidated financial statements are unaudited and are presented in accordance with the requirements for quarterly reports on Form 10-Q and consequently do not include all of the information and footnote disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). The Company’s consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary in the opinion of management to present fairly our interim financial position and results of operations and cash flows for the periods presented. The accompanying condensed consolidated financial statements are presented in accordance with GAAP and the rules and regulations of the Securities and Exchange Commission (“SEC”). Our consolidated financial statements include all necessary reclassification adjustments to conform prior year results to the current period presentation. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with our consolidated financial statements, and notes thereto, included in our Annual Report on Form 10-K for the year ended December 31, 2014. Operating results for the periods in these condensed consolidated financial statements are not necessarily indicative of the results for any future period. The accompanying condensed consolidated financial statements include the accounts of Westwood and its subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation. Business Combinations In allocating the purchase price of a business combination, the Company records all assets acquired and liabilities assumed at fair value, with the excess of the purchase price over the aggregate fair values recorded as goodwill. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values as of the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. The Company determines the estimated fair values after review and consideration of relevant information, including discounted cash flows, quoted market prices and estimates made by management. The fair value assigned to identifiable intangible assets acquired is based on estimates and assumptions made by management at the time of the acquisition. The Company adjusts the preliminary purchase price allocation, as necessary, during the measurement period of up to one year after the acquisition closing date as it obtains more information as to facts and circumstances existing as of the acquisition date. Acquisition-related costs are recognized separately from the acquisition and are expensed as incurred. The acquired customer accounts, tradenames and non-compete agreements are subject to fair value measurements based primarily on significant inputs not observable in the market and thus represent Level 3 measurements. The valuation of an acquired customer list utilizes an income approach, which provides an estimate of the fair value of an asset based on discounted cash flows and management estimates, including the estimated growth associated with existing clients, market growth and client attrition. The valuation of acquired tradenames uses a relief from royalty method in which the fair value of the intangible asset is estimated to be the present value of royalties saved because the intangible asset is owned by the Company. Revenue projections and estimated useful lives are used in estimating the fair value of the trademarks. The non-compete agreements are calculated using the with-or-without method, which utilizes the probability of these employees competing with the Company and revenue projections to calculate the valuation of non-competition agreements. When an acquisition includes future contingent consideration on achieving certain annualized revenue from the post-closing acquired business over a specified time period, the Company estimates the fair value of the earn-out using overall revenue growth projections combined with existing customer base lost revenue projections, both discounted and probability-weighted. A liability is recorded for the estimated fair value of the contingent consideration on the acquisition date, and the fair value of the contingent consideration is remeasured at each subsequent reporting period with any change in fair value recognized as income or expense within the consolidated statement of comprehensive income. Recent Accounting Pronouncements In April 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-8, Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which changes the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. The ASU is intended to reduce the frequency of disposals reported as discontinued operations by focusing on strategic shifts that have (or will have) a major effect on an entity’s operations and financial results. The adoption of this ASU did not have an impact on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-9, Revenue from Contracts with Customers (Topic 606), which resulted from a joint project by the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards. The issuance of a comprehensive and converged standard on revenue recognition is expected to improve the ability of financial statement users to understand and consistently analyze an entity’s revenue across industries, transactions, and geographies. The standard will require additional disclosures to help financial statement users better understand the nature, amount, timing, and potential uncertainty of the revenue being recognized. ASU 2014-9 will be effective for annual reporting periods beginning after December 15, 2017, and will require either retrospective application to each prior reporting period presented or retrospective application with the cumulative effect of initially applying the standard recognized at the date of adoption. Early application is prohibited. We are currently evaluating the impact that the application of ASU 2014-9 will have on our consolidated financial statements and disclosures. In June 2014, the FASB issued ASU 2014-12 Compensation—Stock Compensation (Topic 718) Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period, which establishes specific guidance on how to account for share-based payments for awards with performance targets after the employee completes the requisite service period. Current U.S. GAAP does not contain explicit guidance on how to account for such share-based payments. The standard will be effective for annual reporting periods beginning after December 15, 2015, although early adoption is permitted. We do not currently expect the adoption of this ASU to have a significant impact on our consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The ASU will explicitly require management to assess an entity’s ability to continue as a going concern and to provide related footnote disclosure in certain circumstances. The new guidance will be effective for the year ending December 31, 2016. Earlier adoption is permitted. We do not expect the adoption of this ASU to have an impact on our consolidated financial statements. In January 2015, the FASB issued ASU 2015-1, Income Statement – Extraordinary and Unusual Items. The ASU eliminates the concept of extraordinary items, which are currently required to be separately classified, presented and disclosed in financial statements. ASU 2015-1 is effective for annual reporting periods, including interim periods within those periods, beginning after December 31, 2015. We do not expect the adoption of this ASU to have an impact on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-2, Consolidation – Amendments to the Consolidation Analysis. This amendment modifies the analysis required to evaluate whether certain legal entities should be consolidated, including variable interest entities. This amendment changes the evaluation of fee arrangements and related party transactions when determining whether to consolidate a variable interest entity. The amendment is effective for annual reporting periods beginning after December 15, 2016 and for interim periods within reporting periods beginning after December 15, 2017, although early adoption is permitted. We are currently evaluating the impact that the application of ASU 2015-2 will have on our consolidated financial statements and disclosures. In April 2015, the FASB issued ASU 2015-5, Intangibles – Goodwill and Other – Internal-Use Software. This amendment provides guidance about whether a cloud computing arrangement includes a software license. The new guidance clarifies that software licenses included in a cloud computing software should be accounted for in the same manner as other software licenses. If the cloud computing arrangement does not include a software license, the arrangement should be accounted for as a service contract. This amendment is effective for annual reporting periods, including interim periods within those periods, beginning after December 15, 2015, with early adoption permitted. We are currently evaluating the impact that the application of ASU 2015-5 will have on our consolidated financial statements. In May 2015, the FASB issued ASU 2015-07, Fair Value Measurements – Disclosures for Certain Entities that Calculate Net Asset Value per Share. This amendment updates guidance intended to eliminate the diversity in practice surrounding how investments measured at net asset value under the practical expedient with future redemption dates have been categorized in the fair value hierarchy. Under the updated guidance, investments for which fair value is measured at net asset value per share using the practical expedient should no longer be categorized in the fair value hierarchy. The updated guidance requires retrospective adoption for all periods presented and is effective for interim and annual reporting periods beginning after December 15, 2015, with early adoption permitted. Except for the disclosure requirements, we do not expect the adoption of this guidance to impact our consolidated financial statements.
