	1	ORGANIZATION, CONSOLIDATION AND PRESENTATION OF FINANCIAL STATEMENTS
	Business Description: West Corporation (the “Company” or “West”) is a leading 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. Our services include conferencing and collaboration, public safety services, Internet Protocol (“IP”) communications, interactive services such as automated notifications, large-scale agent services and telecom services. The scale and processing capacity of our proprietary technology platforms, combined with our expertise in managing voice and data transactions, enable us to provide reliable, high-quality, mission-critical communications designed to maximize return on investment for our clients. Our clients include Fortune 1000 companies, along with small and medium enterprises in a variety of industries, including telecommunications, retail, financial services, public safety, technology and healthcare. We have sales and operations in the United States, Canada, Europe, the Middle East, Asia-Pacific, Latin America and South America.
	We operate in two reportable segments:
		•	Unified Communications, including conferencing and collaboration, IP communications and interactive services; and
		•	Communication Services, including public safety services, telecom services and agent services.
	Effective January 1, 2014, we implemented a revised organizational structure which our Chief Executive Officer utilizes for making strategic and operational decisions and allocating resources. Under the revised organizational structure, automated call processing services management and operations haves been moved from the Communication Services segment to the Unified Communications segment and have been combined with alerts and notifications to form interactive services. Beginning in the first quarter of 2014, all prior period comparative information has been recast to reflect this change as if it had taken place in all periods presented.
	Unified Communications
	— Conferencing & Collaboration. Operating under the InterCall® brand, we are the largest conferencing services provider in the world based on conferencing revenue, according to Wainhouse Research. During the six months ended June 30, 2014, we managed approximately 80 million conference calls, an 8% percent increase over the same period in 2013. We provide our clients with an integrated global suite of meeting services. InterCall also offers multimedia event services designed to give our clients the ability to create, manage, distribute and reuse content internally and externally. Through a combination of proprietary products and strategic partnerships, our clients have the tools to support diverse internal and external multimedia requirements.
	— IP Communications. We provide our clients with enterprise class IP communications solutions enabled by our technology. We offer hosted IP-private branch exchange (“PBX”) and enterprise call management, hosted and managed multiprotocol label switching (“MPLS”) network solutions, unified communications partner solution portfolio services, cloud-based security services and professional services and systems integration expertise.
	— Interactive Services. We help our clients automate, navigate and solve their communication challenges across the customer lifecycle. We design, integrate, deliver and manage applications, services, platforms and networks that aim to improve the customer experience and drive efficiencies for our clients. 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 an automated customer experience across channels. In 2013, our interactive voice response (“IVR”), hosted contact center, and alerts and notifications platforms received and delivered 2.8 billion calls and data messages on behalf of our clients.
	Communication Services
	— Public Safety Services. We believe we are one of the largest providers of public safety services, based on the number of 9-1-1 calls that we and other participants in the industry facilitate. Our services are critical in facilitating public safety agencies’ ability to receive emergency calls from citizens.
	— Telecom Services. Our telecom services support the merging of traditional telecom, mobile and IP technologies to service providers and enterprises. We are a leading provider of local and national tandem switching services to carriers throughout the United States. We leverage our proprietary customer traffic information system, sophisticated call routing and control facility to provide tandem interconnection services to the competitive marketplace, including wireless, wire-line, cable telecom and Voice over Internet Protocol (“VoIP”) companies.
	— Agent Services. We provide our clients with large-scale agent services. We target opportunities that allow our agent services to be a part of larger strategic client engagements and with clients for whom these services can add value. We believe that we are known in the industry as a premium provider of these services. We offer a flexible model that includes on-shore, off-shore and home-based agent capabilities to fit our clients’ needs. With the acquisition of Health Advocate, Inc (“Health Advocate”) on June 13, 2014, we expanded our Agent Service presence in the healthcare industry.
	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 adjustments) 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 consolidated financial statements and notes thereto, contained in our Annual Report on Form 10-K for the year ended December 31, 2013. All intercompany balances and transactions have been eliminated. Our results for the three and six months ended June 30, 2014 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—Conferencing services are generally billed and revenue recognized on a per participant minute basis. Web collaboration services are generally billed and revenue recognized on a per participant minute basis or, in the case of operating license arrangements, generally billed in advance and revenue recognized ratably over the service life period. IP communications services are generally billed and revenue recognized on a per seat basis. Interactive services are generally billed, and revenue recognized, on a per call, per message or per minute basis, or ratably over the contract term. We also charge clients for additional features, such as conference call recording, transcription services or professional services. Public safety services revenue is generated primarily from monthly fees based on the number of billing telephone numbers and cell towers covered under contract. In addition, product sales and installations are generally recognized upon completion of the installation and client acceptance of a fully functional system or, for contracts that are completed in stages, recognized upon completion of such stages and client acceptance. Contracts for annual recurring services such as support and maintenance agreements are generally billed in advance and are recognized as revenue ratably (on a monthly basis) over the contractual periods.
	Revenue for telecom services is recognized in the period the service is provided and when collection is reasonably assured. These telecom services are primarily comprised of switched access charges for toll-free origination services, which are paid primarily by interexchange carriers.
	Agent services revenue is generated in the month that services are performed, and services are generally billed based on call duration, hours of input, number of calls or a contingent basis. Revenue for contingent collection services and overpayment identification and recovery services is recognized in the month collection payments are received based upon a percentage of cash collected or other agreed upon contractual parameters. Revenue for health advocacy services is based on Per Employee Per Month (“PEPM”) fees charged under prepayment agreements for services and is recognized as revenue for the periods billed. Fees for future service periods are deferred until the service is performed.
	Dividend—We funded the dividends paid in 2013 and the first six months of 2014 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 February 20, 2014 and May 15, 2014, we paid a $0.225 per common share quarterly dividend. The total dividend paid was approximately $18.9 million to shareholders of record as of the close of business on February 10, 2014 and May 5, 2014, respectively, for a total of $37.8 million.
	Recent Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers” (Topic 606) (“ASU 2014-09”). ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. In adopting ASU 2014-09, companies may use either a full retrospective or a modified retrospective approach. ASU 2014-09 is effective for the first interim period within annual reporting periods beginning after December 15, 2016, and early adoption is not permitted. The Company will adopt ASU 2014-09 during the first quarter of fiscal 2017. We are still assessing the impact on the Company’s consolidated condensed financial statements.

	SchoolMessenger
	On April 21, 2014, we acquired Reliance Holding, Inc., doing business through its wholly owned subsidiary Reliance Communications, LLC as SchoolMessenger (“SchoolMessenger”), a leading provider of notification and mobile communication solutions for the K-12 education market. The purchase price was approximately $76.5 million and was funded by cash on hand.
	In the preliminary purchase price allocation, goodwill of $51.5 million, not deductible for tax purposes, and finite-lived intangible assets of $40.1 million were recorded. The acquisition was integrated into our Unified Communications segment, within interactive services, to expand our interactive services into an adjacent market, the education vertical.
	The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the acquisition date for SchoolMessenger. The finite-lived intangible assets are comprised of trade names, technology, non-competition agreements and customer relationships.

	Heath Advocate
	On June 13, 2014, we acquired Health Advocate, Inc. (“Health Advocate”), a leading provider of healthcare advocacy services. The purchase price was approximately $265.4 million and was funded by cash on hand and use of our revolving trade accounts receivable financing facility.
	Health Advocate estimates it serves over 40 million Americans through more than 10,000 client relationships, including many of the nation’s largest employers, by helping members personally navigate healthcare and insurance-related issues, saving them time and money. Health Advocate leverages the power of pricing transparency and personalized health communications to help members make better informed decisions and get more value out of the healthcare system. Additional services include wellness coaching, employee assistant programs (EAPs), a nurse line, biometrics screenings and chronic care solutions. Health Advocate’s technology platform combined with clinical and health plan and claims billing experts can support consumers with a wide range of healthcare or health insurance issues.
	In the preliminary purchase price allocation, goodwill of $163.4 million, not deductible for tax purposes, and finite-lived intangible assets of $150.2 million were recorded. The acquisition was integrated into our Communication Services, within agent services, to expand our services in the healthcare industry. Further, Health Advocate’s strong competitive position in the health advocacy market and Health Advocate’s suite of consumer focused services and health solutions provides cross-selling opportunities with our existing healthcare client base.
	The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the acquisition date for Health Advocate. The finite-lived intangible assets are comprised of trade names, technology, non-competition agreements and customer relationships.

	Senior Secured Term Loan Facility and Senior Secured Revolving Credit Facility.
	On January 24, 2014, we modified our senior secured term loan facilities (“Senior Secured Credit Facilities”) by entering into Amendment No. 4 to the Amended and Restated Credit Agreement (the “Credit Agreement”) among West Corporation, certain of our domestic subsidiaries, Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent, and the various lenders party thereto (the “Fourth Amendment). The Fourth Amendment provided for a 25 basis point reduction in the applicable LIBOR interest rate margins and a 25 basis point reduction in the LIBOR interest rate floors of all term loans. As of June 30, 2014, the interest rate margins applicable to the term loans due June 30, 2018 were 2.50% for LIBOR rate loans and 1.50% for base rate loans, and the interest rate margins applicable to the term loans due July 15, 2016 were 2.0% for LIBOR rate loans and 1.0% for base rate loans. The Fourth Amendment also provides for interest rate floors applicable to the term loans. The interest rate floors effective June 30, 2014 were 0.75% for LIBOR rate loans and 1.75% for base rate loans.
	In connection with the Fourth Amendment, we incurred refinancing expenses of approximately $5.8 million, which will be amortized into interest expense over the remaining life of the Amended Credit Agreement.
	At June 30, 2014, we were in compliance with our financial debt covenants.
	On July 1, 2014, the Company, Wells Fargo, as administrative agent, and the various lenders party thereto further modified our Senior Secured Credit Facilities by entering into Amendment No. 5 to Amended and Restated Credit Agreement (the “Fifth Amendment”, and the Credit Agreement, as previously amended and further amended by the Fifth Amendment, the “Amended Credit Agreement”). The Fifth Amendment provided for:
	• a new delayed draw term loan A facility (the “TLA”) to be made available, in a single borrowing, at any time on or before December 31, 2014 in the form of TLA loans having terms substantially similar to the existing term loans under our Senior Secured Credit Facilities, except with respect to pricing, amortization and maturity, in an aggregate principal amount of $350.0 million. The TLA matures July 1, 2019. The proceeds of the TLA will be used at our option (i) to prepay in part Senior Secured Term Loan Facilities due in 2016 and 2018 and pay accrued but unpaid interest thereon, (ii) to redeem any of our 7.875% Senior Notes due 2019, (iii) for working capital and general corporate purposes and (iv) to pay fees and expenses incurred in connection with the TLA;
	• annual amortization (payable in quarterly installments) in respect of the TLA at a 2.5% annual rate in the year ending June 30, 2015, a 5.0% annual rate in the year ending June 30, 2016, a 7.5% annual rate in the year ending June 30, 2017 and a 10.0% annual rate thereafter until the maturity date, at which point all remaining amounts outstanding under the TLA shall become due and payable;
	• an interest rate margin applicable to the TLA that is based on the Company’s total leverage ratio and ranges from 1.50% to 2.25% for LIBOR rate loans and from 0.50% to 1.25% for base rate loans;
	• a senior secured revolving credit facility (the “Senior Secured Revolving Credit Facility”) to be made available under the Amended Credit Agreement in replacement of, and in the form of revolving credit loans having terms substantially similar to, the existing senior secured revolving credit facility under our Credit Agreement (except with respect to pricing and maturity), in an aggregate principal amount of $300.0 million that matures July 1, 2019; and
	• an interest rate margin applicable to the Senior Secured Revolving Credit Facility that is based on the Company’s total leverage ratio and ranges from 1.50% to 2.25% for LIBOR rate loans and from 0.50% to 1.25% for base rate loans.
	2022 Senior Notes
	On July 1, 2014, we issued $1.0 billion aggregate principal amount of our 5.375% Senior Notes due 2022 (the “2022 Senior Notes”). The 2022 Senior Notes mature on July 15, 2022 and were issued at par. The 2022 Senior Notes were offered in a private offering exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”).
	The net proceeds from the offering were approximately $986.5 million, after deducting underwriting discounts and offering expenses. On July 1, 2014, we used a portion of the net proceeds from the 2022 Senior Notes to repurchase pursuant to tender offers:
		•		$270.8 million aggregate principal amount of the 8.625% Senior Notes due 2018 (the “2018 Senior Notes”). The aggregate repurchase price for the 2018 Senior Notes was $298.7 million including accrued interest of $10.8 million and tender offer premium of $17.1 million;
		•		$200.0 million aggregate principal amount of the 7.875% Senior Notes due 2019 (the “2019 Senior Notes”). The aggregate repurchase price for the 2019 Senior Notes was $215.3 million including accrued interest of $2.0 million and tender offer premium of $13.3 million.
	In addition, on July 1, 2014, we used a portion of the net proceeds from the 2022 Senior Notes to repay a portion of the Senior Secured Term Loan Facility due 2018. The total aggregate principal amount repaid on the Senior Secured Term Loan Facility due 2018 was $250.0 million.
	On July 17, 2014, we used a portion of the net proceeds from the 2022 Senior Notes, together with cash on hand to redeem the remaining $229.2 million aggregate principal amount of the 2018 Senior Notes for an aggregate redemption price of $242.9 million including payments of the $9.9 million redemption premium, $3.7 million make-whole premium and accrued interest of $0.1 million.
	The 2022 Senior Notes bear interest at a rate of 5.375% per year, payable semiannually in arrears on July 15 and January 15 of each year, beginning January 15, 2015. The 2022 Senior Notes will mature July 15, 2022. The 2022 Senior Notes are unsecured senior obligations and rank equally in right of payment with all of our future senior debt and are senior to all of our future subordinated debt. Each of our domestic wholly owned subsidiaries that guarantees our Senior Secured Credit Facilities guarantee the notes with guarantees that rank equal in right of payment to all existing and future senior debt of such subsidiary. The 2022 Senior Notes and guarantees are effectively subordinated to our existing and future secured debt and that of the guarantors to the extent of the value of the assets securing such debt.
	2018 Senior Notes
	In connection with the issuance of the 2022 Senior Notes, on June 17, 2014, we commenced a tender offer to purchase any and all of our outstanding $500.0 million in aggregate principal amount of the 2018 Senior Notes. Total offer consideration for each $1,000 principal amount of the 2018 Senior Notes tendered was $1,063.09, including an early tender premium of $20.00 per $1,000 principal amount of the 2018 Senior Notes for those holders who properly tendered their 2018 Senior Notes on or before June 30, 2014. Upon consummation of the tender offer on July 1, 2014, approximately $270.8 million aggregate principal amount of the 2018 Senior Notes was purchased. Total consideration paid for the tender offer, including early tender premium payment and accrued interest, was approximately $298.7 million.
	The redemption date for the call of the 2018 Senior Notes was July 17, 2014 at a redemption price equal to 104.313% of the principal amount of the 2018 Senior Notes and make whole-premium. The Company redeemed the remaining $229.2 million aggregate principal amount of the 2018 Senior Notes for an aggregate redemption price of $242.9 million including payments of the $9.9 million redemption premium, $3.7 million make-whole premium and accrued interest of $0.1 million. Following this redemption, none of the 2018 Senior Notes remained outstanding.
	2019 Senior Notes
	In connection with the issuance of the 2022 Senior Notes, on June 17, 2014, we commenced a tender offer to purchase up to $200.0 million in aggregate principal amount of the 2019 Senior Notes. Total offer consideration for each $1,000 principal amount of the 2019 Senior Notes tendered was $1,066.29, including an early tender premium of $20.00 per $1,000 principal amount of the 2019 Senior Notes for those holders who properly tendered their 2019 Senior Notes on or before June 30, 2014. Upon consummation of the tender offer on July 1, 2014, $200.0 million aggregate principal amount of the 2019 Senior Notes was purchased. Total consideration paid for the tender offer, including early tender premium payment and accrued interest, was approximately $215.3 million.

HEDGING ACTIVITIES	'
	6	HEDGING ACTIVITIES
	Periodically, we have entered into interest rate swaps to hedge the cash flows from our variable rate debt, which effectively converts the hedged portion under our outstanding senior secured term loan facility to fixed rate debt. The initial assessments of hedge effectiveness were performed using regression analysis. The periodic measurements of hedge ineffectiveness are performed using the change in variable cash flows method. The cash flow hedges were recorded at fair value with a corresponding entry, net of taxes, recorded in other comprehensive income (“OCI”) until earnings were affected by the hedged item. In June 2013, three interest rate swaps with an aggregate notional value of $500.0 million matured. The interest rate on these three interest rate swaps ranged from 1.685% to 1.6975%. At June 30, 2014 and December 31, 2013, we did not have any interest rate swaps.

FAIR VALUE DISCLOSURES

Accounting Standards Codification 820 Fair Value Measurements and Disclosures (“ASC 820”) defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The provisions of ASC 820 apply to other accounting pronouncements that require or permit fair value measurements. ASC 820:

•

Defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date; and

•

Establishes a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date.

Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. To increase consistency and comparability in fair value measurements and related disclosures, the fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The three levels of the hierarchy are defined as follows:

•

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities.

•

Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly for substantially the full term of the financial instrument.

•

Level 3 inputs are unobservable inputs for assets or liabilities.

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.

We evaluate classification within the fair value hierarchy at each period. There were no transfers between any levels of the fair value hierarchy during the periods presented.

Assets and liabilities measured at fair value on a recurring basis, in thousands, are summarized below:

The fair value of our 8.625% senior notes and 7.875% senior notes based on market quotes, which we determined to be Level 1 inputs, at June 30, 2014 was approximately $1,221.4 million compared to the carrying amount of $1,150.0 million. The fair value of our 8.625% senior notes and 7.875% senior notes based on market quotes, which we determined to be Level 1 inputs, at December 31, 2013 was approximately $1,243.7 million compared to the carrying amount of $1,150.0 million.

The fair value of our Senior Secured Credit Facilities was estimated using current market quotes on comparable debt securities from various financial institutions. All of the inputs used to determine the fair 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 Credit Facilities at June 30, 2014 was approximately $2,361.7 million compared to the carrying amount of $2,375.3 million. The fair value of our Senior Secured Credit Facilities at December 31, 2013 was approximately $2,385.0 million compared to the carrying amount of $2,375.3 million.

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
	Prior to the completion of our initial public offering (“IPO”) on March 27, 2013, we adopted, and subsequently amended, the 2013 Long-Term Incentive Plan (as amended, “2013 LTIP”) which 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 will be available for stock options, restricted stock or other types of equity awards granted under the 2013 LTIP, subject to adjustment for stock splits and other similar changes in capitalization. The number of available shares will be reduced by the aggregate number of shares that become subject to outstanding awards granted under the 2013 LTIP. 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.
	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.

	At June 30, 2014, we expect that approximately 20% of options granted will be canceled or forfeited over the vesting period. At June 30, 2014, the intrinsic value of options vested and exercisable was approximately $2.2 million. The aggregate intrinsic value of options outstanding at June 30, 2014, was approximately $5.2 million. The aggregate intrinsic value of options outstanding, vested and expected to vest at June 30, 2014, was approximately $4.8 million.

	The executive management rollover options are fully vested and have an average remaining life of 1.1 years. The aggregate intrinsic value of these options at June 30, 2014 was approximately $0.3 million.
	We account for the stock option grants under the 2006 EIP and 2013 LTIP in accordance with Accounting Standards Codification 718, Compensation-Stock Compensation. The fair value of each option granted was estimated on the date of grant using a Black-Scholes option pricing model with the following weighted average assumptions for grants during the period.

	Expected life (years)			6.25			6.25
	Fair value of the option award		$	4.9		$	9.04
	The risk-free interest rate for periods within the expected life of the option is based on the zero-coupon U.S. government treasury strip with a maturity which approximates the expected life of the option at the time of grant.
	At June 30, 2014 and 2013, there was approximately $11.4 million and $12.8 million, respectively, of unrecorded and unrecognized compensation expense related to unvested stock options under the 2006 EIP and 2013 LTIP in aggregate, which will be recognized over the remaining vesting period of approximately 2.0 years as of June 30, 2014.
	Restricted Stock
	During the six months ended June 30, 2014, pursuant to our agreement with our non-employee directors who are not affiliated with our former sponsors, we issued 12,591 shares of common stock with an aggregate fair value of approximately $300,000. 4,203 of these shares were granted to a new non-employee director and are fully vested subject to a pro rata forfeiture if the director does not remain on the board for at least six months. The remaining 8,388 shares were issued as an annual equity grant to our other two non-employee directors who are not affiliated with our former sponsors. These shares vest on the one-year anniversary of the date of grant.
	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. 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 five percent (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. As of June 30, 2014, 153,375 shares had been issued under the ESPP. For the three and six months ended June 30, 2014, we recognized compensation expense for this plan of $0.3 million and $0.6 million, respectively.
	Stock-Based Compensation Expense
	For the three months ended June 30, 2014 and 2013, stock-based compensation expense was $2.6 million and $1.9 million, respectively. For the six months ended June 30, 2014 and 2013, stock-based compensation expense was $6.2 million and $5.0 million, respectively.

	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 assume the exercise of stock options using the treasury stock method.

	Diluted Common Shares			85,398		84,943		85,312		75,151
	Diluted earnings per share are computed using the weighted-average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares result from the assumed exercise of outstanding stock options, by application of the treasury stock method, that have a dilutive effect on earnings per share. At June 30, 2014 and 2013, 675,352 and 2,718,599 stock options were outstanding with an exercise price equal to or exceeding the market value of our common stock, these shares were therefore excluded from the computation of shares contingently issuable upon exercise of the options.

	We operate in two business segments:
	Unified Communications, including conferencing and collaboration, IP communications and interactive services; and
	Communication Services, including public safety services, telecom services and agent services.
	Effective January 1, 2014, we implemented a revised organizational structure which our Chief Executive Officer utilizes for making strategic and operational decisions and allocating resources. Under the revised organizational structure, automated call processing services management and operations have been moved from the Communication Services segment to the Unified Communications segment and have been combined with alerts and notifications to form interactive services. Beginning in the first quarter of 2014, all prior period comparative information has been recast to reflect this change as if it had taken place in all periods presented.

ORGANIZATION_CONSOLIDATION_AND1

ORGANIZATION, CONSOLIDATION AND PRESENTATION OF FINANCIAL STATEMENTS (Policies)	6 Months Ended
	Jun. 30, 2014
Accounting Policies [Abstract]	'
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 adjustments) 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 consolidated financial statements and notes thereto, contained in our Annual Report on Form 10-K for the year ended December 31, 2013. All intercompany balances and transactions have been eliminated. Our results for the three and six months ended June 30, 2014 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 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 Recognition—Conferencing services are generally billed and revenue recognized on a per participant minute basis. Web collaboration services are generally billed and revenue recognized on a per participant minute basis or, in the case of operating license arrangements, generally billed in advance and revenue recognized ratably over the service life period. IP communications services are generally billed and revenue recognized on a per seat basis. Interactive services are generally billed, and revenue recognized, on a per call, per message or per minute basis, or ratably over the contract term. We also charge clients for additional features, such as conference call recording, transcription services or professional services. Public safety services revenue is generated primarily from monthly fees based on the number of billing telephone numbers and cell towers covered under contract. In addition, product sales and installations are generally recognized upon completion of the installation and client acceptance of a fully functional system or, for contracts that are completed in stages, recognized upon completion of such stages and client acceptance. Contracts for annual recurring services such as support and maintenance agreements are generally billed in advance and are recognized as revenue ratably (on a monthly basis) over the contractual periods.
	Revenue for telecom services is recognized in the period the service is provided and when collection is reasonably assured. These telecom services are primarily comprised of switched access charges for toll-free origination services, which are paid primarily by interexchange carriers.
	Agent services revenue is generated in the month that services are performed, and services are generally billed based on call duration, hours of input, number of calls or a contingent basis. Revenue for contingent collection services and overpayment identification and recovery services is recognized in the month collection payments are received based upon a percentage of cash collected or other agreed upon contractual parameters. Revenue for health advocacy services is based on Per Employee Per Month (“PEPM”) fees charged under prepayment agreements for services and is recognized as revenue for the periods billed. Fees for future service periods are deferred until the service is performed.
Dividend	'
	Dividend—We funded the dividends paid in 2013 and the first six months of 2014 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 February 20, 2014 and May 15, 2014, we paid a $0.225 per common share quarterly dividend. The total dividend paid was approximately $18.9 million to shareholders of record as of the close of business on February 10, 2014 and May 5, 2014, respectively, for a total of $37.8 million.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers” (Topic 606) (“ASU 2014-09”). ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. In adopting ASU 2014-09, companies may use either a full retrospective or a modified retrospective approach. ASU 2014-09 is effective for the first interim period within annual reporting periods beginning after December 15, 2016, and early adoption is not permitted. The Company will adopt ASU 2014-09 during the first quarter of fiscal 2017. We are still assessing the impact on the Company’s consolidated condensed financial statements.
