Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements	1. ORGANIZATION, CONSOLIDATION AND PRESENTATION OF FINANCIAL STATEMENTS Business Description: West Corporation (the “Company” or “West”) is a global provider of technology-enabled communication services. “We,” “us” and “our” also refer to West and its consolidated subsidiaries, as applicable. We offer a broad range of communication and network infrastructure solutions that help manage or support essential communications. These solutions include unified communications services, safety services, interactive services such as automated notifications, specialized agent services and telecom services. The scale and processing capacity of our technology platforms, combined with our expertise in managing multichannel interactions, enable us to provide reliable, high-quality, mission-critical communications designed to maximize return on investment for our clients and help them build smarter, more meaningful connections. We are dedicated to delivering and improving upon new channels, new capabilities and new choices for how businesses and consumers collaborate, connect and transact. Our clients include Fortune 1000 companies, along with small and medium enterprises in a variety of industries, including telecommunications, retail, financial services, public safety, education, technology and healthcare. We have sales and/or operations in the United States, Canada, Europe, the Middle East, Asia-Pacific, Latin America and South America. Our Services • Unified Communications Services. We provide our clients with a range of integrated unified communications services. We offer our clients a complete cloud-based unified communications solution which consists of enterprise voice, conferencing and collaboration, network management, unified messaging and presence, contact center and client application integration. We combine reliable technologies with experience and flexibility to provide solutions that are easy to use and scalable for every client’s specific needs. Our products and services can improve many aspects of business by enabling personalized engagement, meetings anywhere, enhanced productivity and immersive communication experiences. • Telecom Services. We provide local and national tandem switching services that facilitate an efficient exchange of network traffic between originating and terminating networks throughout the U.S. We connect people and unite networks by delivering interconnection services for all types of providers, including wireless, wireline, cable and voice over internet protocol (“VoIP”). We operate a next-generation technology-agnostic national network providing a cost effective means for time-division multiplexing to internet protocol (“IP”) conversion for IP networks that require access to the public switched telephone network. We provide carrier-grade interconnections that reduce cost and merge traditional telecom, mobile and IP technologies onto a common, efficient backbone. Telecom Services also provides much of the telecommunications network infrastructure that supports our conferencing and collaboration business. • Safety Services. We provide 9-1-1 call routing, call location creation and delivery, and call delivery and accuracy compliance tools to the majority of U.S.-based telecommunications service providers. We provide technology solutions for wireline and wireless carriers; satellite, telematics and cable operators; VoIP providers; alarm/security companies; as well as public safety, government agencies and enterprises. West services the public and personal safety ecosystem with networks and an understanding of safety needs. We continue to innovate and develop next-generation industry solutions that match new technologies. We connect people to first responders—firefighters, law enforcement, ambulance services, and the telecommunicators answering calls in public safety answering points. Our seamless and fault tolerant infrastructure along with our data management experience and expertise are the underpinning for individuals’ requests for assistance that require the ability to be located, and have calls routed and delivered to the correct public safety agency. • Interactive Services. We design, integrate, deliver, manage and optimize applications, services, platforms and networks that aim to create a better customer experience, strengthen customer engagement and drive efficiencies for our clients. We specialize in cloud-based communication solutions that drive a smart, personalized and convenient customer experience, including interactive voice response (“IVR”) self-service, proactive notifications and mobility, cloud contact center and comprehensive professional services. Our technology uses an omni-channel approach that brings together voice, text, email, push notification, fax, video, web, social media, hosted contact center and mobile to create a connected customer experience across channels. Our high-capacity and high-availability platform can be deployed in a number of ways and integrated with other inbound and outbound communication channels. In most cases, our technology also directly interfaces with our clients’ internal systems, including customer relationship management, private branch exchange and enterprise reporting platforms. • Specialized Agent Services. We provide our clients a combination of highly skilled subject matter experts with proven analytics and technology to provide solutions for the fast-growing healthcare market. We believe we are the leading provider of healthcare advocacy products and services to employees of large organizations. We also help health insurance payers, third-party administrators and self-insured employers improve cash flow and reduce healthcare costs by identifying and recovering overpaid and third-party liability claims. Additionally, we offer business-to-business sales across multiple vertical markets with a focus on increasing our clients’ market share and improving customer relationships. Our five operating segments (Unified Communications Services, Telecom Services, Safety Services, Interactive Services and Specialized Agent Services) are aggregated into four reportable segments as follows: • Unified Communications Services, which includes conferencing and collaboration services, unified communications as a service (“UCaaS”) solutions and telecom services; • Safety Services, including 9-1-1 network services, 9-1-1 telephony systems and services, 9-1-1 solutions for enterprises and database management; • Interactive Services, including proactive notifications and mobility, IVR self-service, cloud contact center and professional services; and • Specialized Agent Services, which includes healthcare advocacy services, cost management services and revenue generation services. Discontinued Operations —On March 3, 2015, we divested several of our agent-based businesses, including our consumer facing customer sales and lifecycle management, account services and receivables management businesses, for $275.0 million in cash. We completed the divestiture pursuant to a purchase agreement executed January 7, 2015 and in accordance with a plan approved by our Board of Directors on December 30, 2014. Basis of Consolidation —The unaudited condensed consolidated financial statements include the accounts of West and its wholly-owned subsidiaries and reflect all adjustments (all of which are normal recurring accruals), which are, in the opinion of management, necessary for a fair presentation of the financial position, operating results and cash flows for the interim periods. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto, together with Management’s Discussion and Analysis of Financial Condition and Results of Operations, contained in our Annual Report on Form 10-K for the year ended December 31, 2015. All intercompany balances and transactions have been eliminated in the consolidated financial statements. Our results for the three and nine months ended September 30, 2016 are not necessarily indicative of what our results will be for other interim periods or for the full fiscal year. Use of Estimates —The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Revenue Recognition —Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, price is fixed or determinable and collectability is reasonably assured. Amounts billed in advance of providing service are deferred and recorded as deferred revenue or other long-term liabilities on the balance sheet until service has been provided. Dividend —We funded the dividends paid in 2015 and the first nine months of 2016 with cash generated by our operations and we anticipate funding future dividends with cash generated by our operations. The declaration and payment of all future dividends, if any, will be at the sole discretion of our Board of Directors. On each of March 3, 2016, May 26, 2016 and September 1, 2016, we paid a $0.225 per common share quarterly dividend. The total dividend paid was approximately $18.8 million, $18.6 million and $18.6 million to stockholders of record as of the close of business on February 22, 2016, May 16, 2016 and August 22, 2016, respectively. On November 1, 2016, we announced a $0.225 per common share quarterly dividend. The dividend is payable November 23, 2016 to stockholders of record as of the close of business on November 14, 2016. Share Repurchase —Under a share repurchase program approved by the Company’s Board of Directors during the first quarter of 2016 authorizing the repurchase of up to an aggregate of $75 million of outstanding common stock, the Company purchased 1,000,000 shares of common stock through the open market during the first nine months of 2016 for an aggregate purchase price of approximately $22.0 million, which was funded with cash on hand. Assets Held for Sale— On June 21, 2016, we completed the sale of land, buildings and improvements which were previously classified as held for sale and primarily used by the agent-based businesses we divested in 2015. Proceeds from the sale were $38.8 million, excluding related expenses. In connection with this sale, we realized a pre-tax gain of approximately $19.0 million. We also entered into a 12-year leaseback agreement for one of the buildings. This lease is classified as an operating lease and the related $6.1 million gain, included in the $19.0 million realized gain, is being deferred and will be recognized over the lease term. Recently Implemented Accounting Pronouncements —In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This ASU requires capitalized debt issuance costs to be presented as a reduction to the carrying value of debt instead of being classified as a deferred charge, as previously required. This ASU became effective for interim and annual reporting periods in fiscal years beginning after December 15, 2015, and interim periods within those annual periods. We adopted this guidance as of January 1, 2016, and as a result have recast the December 31, 2015 consolidated balance sheet to conform to the current period presentation.

Discontinued Operations	2. DISCONTINUED OPERATIONS On March 3, 2015, we divested several of our agent-based businesses for $275.0 million in cash. The divestiture resulted in a 2015 gain of $48.2 million on an after-tax basis which was included within income from discontinued operations. The $48.2 million gain included a $21.6 million tax benefit in 2015 due to the deferred tax benefit associated with excess outside basis over financial reporting basis. The following table summarizes the results of discontinued operations for the three and nine months ended September 30, 2015: Three Months Ended Nine Months Ended (Amounts in thousands) September 30, 2015 September 30, 2015 Revenue $ — $ 102,251 Operating income — 3,851 (Loss) gain on disposal (1,900 ) 46,656 (Loss) income before income tax expense (1,900 ) 50,334 Income tax (benefit) expense (665 ) 19,345 (Loss) income from discontinued operations $ (1,235 ) $ 30,989 There has been no income or loss from discontinued operations during the first three quarters of 2016. We have agreed to indemnify the buyer, up to the full purchase price, with respect to the equity interests of the companies we sold, title to the equity and assets sold and the authority of the Company to sell the equity and assets. The Company has also agreed to indemnify the buyer for breaches of other representations and warranties in the purchase agreement for up to $13.75 million in losses.

Acquisitions	3. ACQUISITIONS Synrevoice On March 14, 2016, we completed the acquisition of substantially all of the assets of Synrevoice Technologies, Inc. (“Synrevoice”). Synrevoice, based in Markham, Ontario, is a provider of messaging and notification services to the K-12 education and commercial markets in North America. The purchase price was approximately $9.3 million and was funded with cash on hand. This business is included in the Interactive Services reportable segment. In the preliminary purchase price allocation, approximately $4.9 million was allocated to goodwill, which is partially deductible for income tax purposes, and $6.5 million was allocated to other intangible assets. The primary factors that contributed to a purchase price resulting in the recognition of goodwill for the acquisition of Synrevoice were the expansion of our interactive services further into the education vertical market and anticipated synergies which are expected to result in a more efficient and faster growing K-12 business in North America. ClientTell On November 2, 2015, we completed the acquisition of ClientTell, Inc., and ClientTell Labs, LLC (collectively “ClientTell”), which provide automated notifications and lab reporting services in the healthcare industry. The purchase price was approximately $38.4 million in cash, plus assumed liabilities, and was funded with cash on hand. Up to an additional $10.5 million in cash may be paid based on achievement of certain financial objectives during the five years ending December 31, 2020. The fair value of this contingent consideration arrangement was $5.4 million as of the date of acquisition and $5.3 million as of September 30, 2016. Pursuant to this arrangement, $1.2 million of payments were made during the nine months ended September 30, 2016. Approximately $15.0 million of the purchase price was allocated to goodwill and $26.3 million to other intangible assets. The goodwill is deductible for income tax purposes. The primary factors that contributed to a purchase price resulting in the recognition of goodwill for the acquisition of ClientTell were the expansion of our interactive services further into the healthcare vertical market, anticipated synergies and other intangibles that do not qualify for separate recognition. This business has been integrated into the Interactive Services reportable segment. Magnetic North On October 31, 2015, we completed the acquisition of Magnetic North Software Limited (“Magnetic North”) for approximately $39.2 million in cash net of cash acquired, plus assumed liabilities, which was funded with cash on hand. Magnetic North is a U.K.-based provider of inbound/outbound/blended, multi-channel customer engagement technology solutions with multi-media routing, advanced analytics and compliance functionality and integrated, hosted voice and unified communications platforms to customers throughout Europe, the Middle East and Africa (“EMEA”) and the Americas. In the preliminary purchase price allocation, approximately $24.8 million was allocated to goodwill and $16.4 million to other intangible assets. The goodwill is not deductible for income tax purposes. The primary factors that contributed to a purchase price resulting in the recognition of goodwill for the acquisition of Magnetic North were its portfolio of complementary customer contact center and unified communications solutions, anticipated synergies and other intangibles that do not qualify for separate recognition. This business has been integrated into the Unified Communications Services reportable segment. SharpSchool Effective June 1, 2015, we completed the acquisition of substantially all of the assets of Intrafinity, Inc., doing business as SharpSchool (“SharpSchool”), a leading provider of website and content management system software-as-a-service solutions for the K-12 education market. The purchase price was approximately $17.2 million and was funded with cash on hand. In the purchase price allocation, goodwill of $8.3 million, partially deductible for tax purposes under Canadian tax rules governing asset acquisitions, and finite-lived intangible assets of $9.1 million were recorded. The primary factors that contributed to a purchase price resulting in the recognition of goodwill for the acquisition of SharpSchool were the expansion of our interactive services further into the education vertical market and anticipated synergies which are expected to result in a more efficient and faster growing K-12 business for West. SharpSchool has been integrated into the Interactive Services reportable segment. The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the respective acquisition dates for Synrevoice and Magnetic North and the final fair value of assets acquired and liabilities assumed for ClientTell and SharpSchool.

Acquisition costs incurred for prospective acquisitions and completed acquisitions for the nine months ended September 30, 2016 and 2015 of $3.4 million and $2.0 million, respectively, are included in selling, general and administrative expenses. The excess of the acquisition costs over the fair value of the assets acquired and liabilities assumed for the purchase of Magnetic North and Synrevoice were assigned to goodwill based on preliminary estimates. We are in the process of completing the acquisition accounting for certain intangible assets and liabilities. The process of completing the acquisition accounting involves numerous time consuming steps for information gathering, verification and review. We expect to finalize this process within twelve months following the respective acquisition dates.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Hedging Activities	7. HEDGING ACTIVITIES We are exposed to market risk from adverse changes in interest rates. Derivatives are used as part of our strategy to manage this risk. The Company does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated as hedges. On July 26, 2016, we entered into four interest rate swaps, two 1-month LIBOR swaps with a combined beginning notional value of $275.0 million and two 3-month LIBOR swaps with a combined beginning notional value of $275.0 million, each with a maturity date of July 17, 2021. The 1-month LIBOR swaps were effective July 29, 2016, with no amortization or variable interest rate floor. The 3-month LIBOR swaps will be effective June 30, 2017, with 1% amortization per year and a 75 basis points LIBOR floor. The contracts provide for the receipt of variable interest rate amounts from the counterparties in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional value. The Company has elected to apply hedge accounting and has designated these interest rate swaps as cash flow hedges of interest payments on a portion of our variable rate term loan debt maturing in 2021 or later. The initial and periodic assessments of hedge effectiveness were performed using regression analysis. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive loss and will be reclassified into earnings, as interest expense, when interest payments are made on the related debt. The pretax unrealized loss associated with our interest rate swaps, which is deferred in accumulated other comprehensive loss at September 30, 2016 is $1.1 million ($0.7 million after taxes). During the next 12 months, the Company estimates that an additional $1.2 million will be reclassified as an increase to interest expense. As of September 30, 2016, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk: Interest Rate Derivative Number of Instruments Notional Value in Thousands Interest Rate Swaps Four $550,000 At September, 30 2016, the Company had 1-month and 3-month LIBOR-based debt in excess of the hedged notional value. The fixed interest rates on the 1-month and 3-month interest rate swaps range from 0.99530% to 1.50200%. The following table presents, in thousands, our derivative financial instruments as well as their classification in the Condensed Consolidated Balance Sheet as of September 30, 2016.

We do not exclude any component of the hedged instrument's gain or loss when assessing ineffectiveness. There was no ineffectiveness associated with our cash flow hedges for the quarter ended September 30, 2016. Any future ineffectiveness associated with our cash flow hedges will be recorded as additional interest expense.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	8. FAIR VALUE DISCLOSURES FASB guidance establishes a three-level fair value hierarchy based upon assumptions (inputs) used to price assets or liabilities. The three levels of inputs used to measure fair value are as follows: • Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 – Observable inputs other than those included within Level 1, such as quoted prices for similar assets and liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets, and • Level 3 – Unobservable inputs for assets or liabilities reflecting our assumptions and best estimate of what inputs market participants would use in pricing the asset or liability. The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Following is a description of the valuation methodologies used for assets and liabilities measured at fair value. Trading Securities (Asset). The assets held in the West Corporation Executive Retirement Savings Plan and the West Corporation Nonqualified Deferred Compensation Plan represent mutual funds, invested in debt and equity securities, classified as trading securities in accordance with the provisions of Accounting Standards Codification 320 Investments—Debt and Equity Securities considering the employee’s ability to change the investment allocation of their deferred compensation at any time. Quoted market prices are available for these securities in an active market; therefore the fair value of these securities is determined by Level 1 inputs. The carrying amount of the trading securities of $64.2 million and $60.1 million at September 30, 2016 and December 31, 2015, respectively, were equal to the quoted prices in active markets for identical assets. Derivatives. Our derivative instruments consist of interest rate swap assets of $0.7 million and interest rate swap liabilities of $1.8 million. (See Note 7.) The fair value of these Level 2 derivative instruments was determined using readily available market observable inputs such as interest rate curves, discount factors and implied volatilities. We evaluate classification within the fair value hierarchy each reporting period. There were no transfers between any levels of the fair value hierarchy during the periods presented. The carrying amount of the trading securities of $64.2 million and $60.1 million at September 30, 2016 and December 31, 2015, respectively, were equal to the quoted prices in active markets for identical assets. The fair value of our 2021 Senior Secured Notes, issued on June 17, 2016, based on market quotes, which we determined to be Level 2 inputs, at September 30, 2016 was approximately $412.0 million, compared to the carrying amount of $400.0 million. The fair value of our 2022 Senior Notes based on market quotes, which we determined to be Level 2 inputs, at September 30, 2016 and December 31, 2015 was approximately $982.5 million and $862.5 million, respectively, compared to the carrying amount of $1.0 billion. The fair value of our senior secured term loan facilities was estimated using current market quotes on comparable debt securities from various financial institutions. All of the inputs used to determine the fair market value of our senior secured term loan facilities are Level 2 inputs and obtained from an independent source. The fair value of our senior secured term loan facilities at September 30, 2016 was approximately $1,134.6 million compared to the carrying amount of $1,127.2 million. The fair value of our senior secured term loan facilities at December 31, 2015 was approximately $2,033.2 million compared to the carrying amount of $2,063.3 million. The fair value of our senior secured A term loans based on recent trading activity, which we determined to be Level 2 inputs, at September 30, 2016 was approximately $669.8 million compared to the carrying amount of $674.8 million. The fair value of our 2019 Maturity Term Loans at December 31, 2015, was approximately $323.4 million compared to the carrying amount of $336.9 million. A Level 3 liability of $5.3 million and $5.6 million was recognized as of September 30, 2016 and December 31, 2015, respectively, for contingent consideration related to the acquisition of ClientTell (see Note 3). The liability was measured at fair value using a Monte Carlo simulation approach and was based on estimated revenues and the present value of related payments over the earn-out period.

Stock-Based Compensation	9. STOCK-BASED COMPENSATION 2006 Executive Incentive Plan Stock options granted under the West Corporation 2006 Executive Incentive Plan (“2006 EIP”) prior to 2012 vest over a period of five years, with 20% of the stock option becoming exercisable on each of the first through fifth anniversaries of the grant date. Stock options granted under the 2006 EIP in 2012 and 2013 vest over a period of four years, with 25% of the stock option becoming exercisable on each of the first through fourth anniversaries of the grant date. Once an option has vested, it generally remains exercisable until the tenth anniversary of the grant date so long as the participant continues to provide services to the Company. 2013 Long-Term Incentive Plan Our Amended and 2013 Long-Term Incentive Plan (as amended, “2013 LTIP”), is intended to provide our officers, employees, non-employee directors and consultants with added incentive to remain employed by or perform services for us and align such individuals’ interests with those of our stockholders. Under the terms of the 2013 LTIP, 8,500,000 shares of common stock were made available for stock options, restricted stock or other types of equity awards, subject to adjustment for stock splits and other similar changes in capitalization. The number of available shares under the 2013 LTIP is reduced by the aggregate number of shares underlying each award. To the extent that shares subject to an outstanding award granted under the 2013 LTIP are not issued or delivered by reason of the expiration, termination, cancellation or forfeiture of such award or by reason of the settlement of such award in cash, then such shares will again be available under the 2013 LTIP (excluding shares withheld by the Company to pay withholding taxes related to an award under the 2013 LTIP). Stock options granted under the 2013 LTIP vest over a period of four years, with 25% of the stock option becoming exercisable on each of the first through fourth anniversaries of the grant date. Once an option has vested, it generally remains exercisable until the tenth anniversary of the grant date so long as the participant continues to provide services to the Company. Time-vested restricted stock and restricted stock units granted under the 2013 LTIP vest over a period of three or four years (excluding awards to directors which vest over a six to 12 month period), with a ratable portion of the restricted stock or restricted stock unit award vesting on each anniversary of the grant date until fully vested, unless earlier forfeited as a result of termination of service to the Company prior to the applicable vesting date. For restricted stock and restricted stock unit awards to our employees, dividends are paid upon vesting. 2006 Executive Incentive Plan and 2013 Long-Term Incentive Plan – Stock Options The following table presents the stock or stock option activity under the 2006 EIP and 2013 LTIP for the nine months ended September 30, 2016.

Restricted Shares, Restricted Stock Units and Performance-Based Restricted Stock Units During the nine months ended September 30, 2016, pursuant to agreements with our non-employee directors who are not affiliated with our former sponsors, we issued 22,432 shares of common stock with an aggregate fair value of approximately $500,000. These shares vest on the six-month anniversary of the date of grant in the case of initial awards and on the one-year anniversary for all other awards. During the nine months ended September 30, 2016, we issued 425,750 time-vested restricted stock awards and restricted stock units to certain key employees. These awards vest ratably with 25% of the award vesting on each of the first through fourth anniversaries of the award date. The fair value of these awards at the date of grant was approximately $9.6 million and will be recognized over the remaining vesting period of approximately 3.4 years as of September 30, 2016. During the nine months ended September 30, 2016, 449,824 restricted stock awards and restricted stock units vested. 366,695 of these awards are outstanding after 83,129 were withheld in settlement of related payroll taxes. During the nine months ended September 30, 2016, we issued 214,500 performance-based restricted stock units to certain key executives. Each performance-based restricted stock unit represents a contingent right to receive between zero and 1.75 shares of West common stock. These performance-based restricted stock units will vest based on the Company’s total shareholder return (“TSR”) percentile ranking over the applicable performance period as compared to the TSR of companies included in the Russell 2000 on both the first and last day of the performance period, which began on March 1, 2016,and ends on February 28, 2019. The fair value of these awards at the date of grant was approximately $4.8 million and will be recognized over the remaining vesting period of approximately 2.4 years as of September 30, 2016. 2013 Employee Stock Purchase Plan During the fourth quarter of 2013, we implemented the 2013 Employee Stock Purchase Plan (“ESPP”), under which the sale of 1.0 million shares of our common stock has been authorized and reserved. On January 28, 2016 the Board approved an amendment to the ESPP to increase the number of shares available under the ESPP by an additional 1.0 million shares of common stock. The amendment was approved by a vote of the stockholders at our May 17, 2016 annual meeting. Employees may designate up to 50% of their annual compensation for the purchase of stock, subject to a per person limit of 2,000 shares in any offering period or calendar year. The price for shares purchased under the ESPP is 85% of the market closing price on the last day of the quarterly purchase period. No employee will be authorized to purchase common stock through the ESPP if, immediately after the purchase, the employee (or any other person whose stock would be attributed to such employee under U.S. tax law) would own stock and/or hold outstanding options to purchase stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or of any parent of the Company or any subsidiary. In addition, no participant will be entitled to purchase stock under the ESPP at a rate which, when aggregated with his or her rights to purchase stock under all other employee stock purchase plans of the Company and its subsidiaries, exceeds $25,000 in fair market value, determined as of the date of grant (or such other limit as may be imposed by U.S. tax law), for each calendar year in which any option granted to the participant under any such plans is outstanding at any time. During the nine months ended September 30, 2016, 294,951 shares were issued under the ESPP. As of September 30, 2016, 852,347 shares had been issued under the ESPP since the plan’s inception. For the three and nine months ended September 30, 2016 and 2015, we recognized compensation expense for this plan of $0.3 million and $1.0 million, respectively. Share-Based Compensation Expense For the three and nine months ended September 30, 2016, share-based compensation expense was $6.1 million and $19.9 million, respectively. For the three and nine months ended September 30, 2015, share-based compensation expense was $5.4 million and $16.8 million, respectively. At September 30, 2016 and 2015, there was approximately $0.6 million and $3.6 million, respectively, of unrecorded and unrecognized compensation expense, adjusted for estimated forfeitures, related to unvested share-based compensation on stock options under the 2006 EIP and 2013 LTIP, which will be recognized over the remaining vesting period of approximately 1.1 At September 30, 2016 and 2015, there was approximately $40.8 million and $46.3 million, respectively, of unrecorded and unrecognized compensation expense, related to unvested share-based compensation on restricted stock under the 2013 LTIP, which will be recognized over the remaining vesting period of approximately 2.4 years as of September 30, 2016.

Earnings Per Share [Abstract]
Earnings Per Share	10. EARNINGS PER SHARE Diluted earnings per share reflects the potential dilution that could result if options or other contingently issuable shares were exercised or converted into common stock and notional shares from the Nonqualified Deferred Compensation Plan were granted. Diluted earnings per common share assumes the exercise of stock options using the treasury stock method.

Dilutive potential common shares result from the assumed exercise of outstanding stock options, by application of the treasury stock method that has a dilutive effect on earnings per share. At September 30, 2016 and 2015, 2,095,012 and 2,055,530 stock options, respectively, were outstanding with an exercise price equal to or exceeding the market value of our common stock and were therefore excluded from the computation of shares contingently issuable upon exercise of the options.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	13. COMMITMENTS AND CONTINGENCIES In the ordinary course of business, we and certain of our subsidiaries are defendants in various litigation matters and are subject to claims from our clients for indemnification, some of which may involve claims for damages that are substantial in amount. Accruals have been made with respect to these matters, where appropriate, which are reflected in the Company’s consolidated financial statements. The Company may enter into discussions regarding settlement of these matters, and may enter into settlement agreements, if it believes settlement is in the best interest of the Company. The matters discussed below, if decided adversely to or settled by the Company, individually or in the aggregate, may result in liability material to the Company’s financial condition and/or results of operations. There are asserted claims against the Company where an unfavorable outcome is considered to be reasonably possible. These claims can generally be categorized in the following areas: (l) commercial disputes with customers or other business partners, which may involve assertion of a breach of the Company’s legal or contractual obligations to the customer or a claim for indemnification for third-party losses; and (2) other matters which may include issues such as employment related claims. The Company’s estimates of the range of reasonably possible losses in excess of any amounts accrued for such claims is $0 to $20 million for all of the matters described above. The estimated range of reasonably possible losses is based on information currently available and involves elements of judgment and significant uncertainties. As additional information becomes available and the resolution of the uncertainties becomes more apparent, it is possible that actual losses may exceed even the high end of the estimated range. In connection with the sale of certain of our agent-based businesses to Alorica Inc., we agreed to indemnify the buyer, up to the full purchase price of $275.0 million, with respect to the equity interests of the companies we sold, title to the equity and assets sold and the authority of the Company to sell the equity and assets. The Company has also agreed to indemnify the buyer for breaches of other representations and warranties in the purchase agreement for up to $13.75 million in losses and for certain other matters.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Discontinued Operations	Discontinued Operations —On March 3, 2015, we divested several of our agent-based businesses, including our consumer facing customer sales and lifecycle management, account services and receivables management businesses, for $275.0 million in cash. We completed the divestiture pursuant to a purchase agreement executed January 7, 2015 and in accordance with a plan approved by our Board of Directors on December 30, 2014.
Basis of Consolidation	Basis of Consolidation —The unaudited condensed consolidated financial statements include the accounts of West and its wholly-owned subsidiaries and reflect all adjustments (all of which are normal recurring accruals), which ar e, in the opinion of management, necessary for a fair presentation of the financial position, operating results and cash flows for the interim periods. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto, together with Management’s Discussion and Analysis of Financial Condition and Results of Operations, contained in our Annual Report on Form 10-K for the year ended December 31, 2015. All intercompany balances and transactions have been eliminated in the consolidated financial statements. Our results for the three and nine months ended September 30, 2016 are not necessarily indicative of what our results will be for other interim periods or for the full fiscal year.
Use of Estimates	Use of Estimates —The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of a ssets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition —Revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, price is fixed or determinable and collectability is reasonably assured. Amounts billed in advance of providing service are deferred and recorded as deferred revenue or other long-term liabilities on the balance sheet until service has been provided.
Dividend	Dividend —We funded the dividends paid in 2015 and the first nine months of 2016 with cash generated by our operations and w e anticipate funding future dividends with cash generated by our operations. The declaration and payment of all future dividends, if any, will be at the sole discretion of our Board of Directors. On each of March 3, 2016, May 26, 2016 and September 1, 2016, we paid a $0.225 per common share quarterly dividend. The total dividend paid was approximately $18.8 million, $18.6 million and $18.6 million to stockholders of record as of the close of business on February 22, 2016, May 16, 2016 and August 22, 2016, respectively. On November 1, 2016, we announced a $0.225 per common share quarterly dividend. The dividend is payable November 23, 2016 to stockholders of record as of the close of business on November 14, 2016.
Share Repurchase	Share Repurchase — Under a share repurchase program approved by the Company’s Board of Directors during the first quarter of 2016 authorizing the repurchase of up to an aggregate of $75 million of outstanding common stock, the Company purchased 1,000,000 shares of common stock through the open market during the first nine months of 2016 for an aggregate purchase price of approximately $22.0 million, which was funded with cash on hand.
Assets Held for Sale	Assets Held for Sale— On June 21, 2016, we completed the sale of land, buildings and improvements which were previously classified as held for sale and primarily used by the agent-based businesses we divested in 2015. Proceeds from the sale were $38.8 million, excluding related expenses. In connection with this sale, we realized a pre-tax gain of approximately $19.0 million. We also entered into a 12-year leaseback agreement for one of the buildings. This lease is classified as an operating lease and the related $6.1 million gain, included in the $19.0 million realized gain, is being deferred and will be recognized over the lease term.
Recently Implemented Accounting Pronouncements	Recently Implemented Accounting Pronouncements —In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. This ASU requires capitalized debt issuance costs to be presented as a reduction to the carrying value of debt instead of being classified as a deferred charge, as previously required. This ASU became effective for interim and annual reporting periods in fiscal years beginning after December 15, 2015, and interim periods within those annual periods. We adopted this guidance as of January 1, 2016, and as a result have recast the December 31, 2015 consolidated balance sheet to conform to the current period presentation. The adoption of this standard reduced previously presented other assets and long-term debt by $57.1 million each, based upon the balance of unamortized debt issuance costs relating to our senior secured term loan facilities and senior notes recorded as of December 31, 2015. In November 2015, the FASB issued ASU 2015-017, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes,
Recent Accounting Pronouncements	Recent Accounting Pronouncements — In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) . The amendments in this update will require a financial asset (or a group of financial assets) measured on an amortized cost basis to be presented at the net amount expected to be collected. This amendment is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018. Adoption of this update is required through a cumulative-effect adjustment to retained deficit as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). The Company is in the process of assessing the impact of this standard on its financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718) In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).
