Organization Consolidation And Presentation Of Financial Statements [Abstract]
General	1. GENERAL We have prepared the accompanying unaudited condensed consolidated financial statements as of June 30, 2018 and December 31, 2017, and for the quarters and six months ended June 30, 2018 and 2017, in accordance with accounting principles generally accepted in the United States of America (“U.S.”) (“GAAP”) for interim financial information, and pursuant to the instructions to Form 10-Q and the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of our management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of our financial position and operating results have been included. The unaudited Condensed Consolidated Financial Statements (the “Financial Statements”) should be read in conjunction with the Consolidated Financial Statements and notes thereto, together with Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), contained in our Annual Report on Form 10-K for the year ended December 31, 2017 (our “2017 10-K”), filed with the SEC. The results of operations for the quarter and six months ended June 30, 2018 are not necessarily indicative of the expected results for the entire year ending December 31, 2018.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates in Preparation of Financial Statements. The preparation of the accompanying Financial Statements in conformity with GAAP 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 our Financial Statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Revenue . We adopted Topic 606 (“ASC 606”) as of January 1, 2018 using the cumulative effect method and have applied ASC 606 to all contracts with clients that had not been completed as of the date of initial application. In conjunction with the adoption of ASC 606, we recorded a cumulative adjustment increasing beginning retained earnings (net of tax) by approximately $7 million, primarily related to contracts that we were previously required to defer revenue as we did not have vendor specific objective evidence (“VSOE”) of fair value for certain undelivered elements. Since we adopted ASC 606 using the cumulative effect method, comparative information in our Financial Statements has not been adjusted and continues to be as previously reported. The following tables summarize the impacts of adopting ASC 606 on our Financial Statements as of and for the quarter and six months ended June 30, 2018 (in thousands, except per share amounts): As of June 30, 2018 Condensed Balance Sheet As Reported Adjustments Balances without adoption of ASC 606 Unbilled trade accounts receivable $ 38,832 $ (614 ) $ 38,218 Other current assets 38,185 3,670 41,855 Client contracts, net of amortization - 69,125 69,125 Acquired client contracts, net of amortization 41,573 (41,573 ) - Client contract costs, net of amortization 35,527 (35,527 ) - Other non-current assets 7,012 4,305 11,317 Other assets 766,102 - 766,102 Total assets (1) $ 927,231 $ (614 ) $ 926,617 Deferred revenue $ 48,632 $ 3,218 $ 51,850 Deferred income taxes 9,162 (179 ) 8,983 Other liabilities 519,577 - 519,577 Total liabilities 577,371 3,039 580,410 Accumulated earnings 772,071 (3,653 ) 768,418 Other stockholders' equity (422,211 ) - (422,211 ) Total stockholders' equity 349,860 (3,653 ) 346,207 Total stockholders' equity and liabilities $ 927,231 $ (614 ) $ 926,617 (1) See Note 3 for further discussion related to the reclassification of our client contracts and client contract costs.

In summary, our revenue from client contracts is primarily related to our cloud and related solutions and, to a lesser degree, software and service and related maintenance arrangements, and is measured based on consideration specified within each of our contracts, excluding sales incentives and amounts collected on behalf of third parties, if any. We account for various products and services separately if they are distinct. A product or service, or group of products or services, is distinct if it is separately identifiable from other items in the context of the contract and if our client can benefit from the product or service on their own or with other resources that are readily available to that client. We recognize revenue when we satisfy our performance obligations by transferring control over a particular product or service, or group of products or services, to our clients, as described in more detail below. Taxes assessed on our products and services based on governmental authorities at the time of invoicing are excluded from our revenue. Cloud and Related Solutions. Our cloud and related solutions revenue relates to: (i) our software-as-a-service (“SaaS”), cloud-based, revenue management and content monetization solutions, and various related ancillary services; and (ii) our managed services offering in which we operate software solutions (primarily our software solutions) on behalf of our clients. We contract for our cloud-based solutions using long-term arrangements whose terms have typically ranged from three to five years. The long-term cloud-based arrangements include a series of multiple services delivered daily or monthly, to include such things as: (i) revenue billing and customer communications management services; (ii) business support services (e.g., workforce management tools, consumer credit verifications, etc.); (iii) content monetization and delivery functions; and (iv) customer statement invoice printing and mailing services. The fees for these services typically are billed to our clients monthly based upon actual monthly volumes and/or usage of services (e.g., the number of client customers maintained on our systems, the number of transactions processed on our systems, and/or the quantity and content of the monthly statements and mailings processed through our systems). For cloud-based solution contracts, the total contract consideration (including impacts of discounts or incentives) is primarily variable dependent upon actual monthly volumes and/or usage of services; however, these contracts can also include ancillary fixed consideration in the form of one-time, monthly or annual fees. Although there may be multiple performance obligations, there is generally no allocation of value between the individual performance obligations as all are considered cloud and related solutions revenues that are recognized based on activities performed in each daily or monthly period. We contract for managed services solutions using long-term arrangements whose terms have typically ranged from three to five years. Under managed services agreements, we may operate software products (primarily our software solutions) on behalf of our clients: (i) out of a client’s data center; (ii) out of a data center we own and operate; or (iii) out of a third-party data center we contract with for such services. Managed services can also include us providing other services, such as transitional services, fulfillment, remittance processing, operational consulting, back office, and end user billing services. The fees for these services typically are billed to our clients monthly on a fixed schedule. For managed services contracts, the total contract consideration is typically a fixed fee, but these contracts may also have variable fee components. Unless managed services are included with a software license contract (as discussed further below), there is generally only one performance obligation and revenue is recognized for these arrangements on a ratable basis as the services are performed. Fees related to set-up or implementation activities for both cloud-based solution and managed services contracts are deferred and recognized ratably over the related service period to which the activities relate. Due to the significance of variable consideration, number of products/services, complex pricing structures and long-term nature of these types of contracts, the judgments and estimates made in this area could have a significant effect on the amount and timing of revenues recognized in any period. Prior to the adoption of ASC 606, we recognized revenue related to our cloud and related solutions contracts on a monthly basis as we provided the services. The adoption of ASC 606 did not result in any significant changes to the timing of revenue recognition related to these contracts. Software and Services. Our software and services revenue relates primarily to: (i) software license sales on either a perpetual or term license basis; and (ii) professional services to implement the software. Our software and services contracts are often contracted in bundled arrangements that include not only the software license and related implementation services, but can also include maintenance, managed services and/or additional professional services. For our software arrangements, the total contract consideration is allocated between the separate performance obligations based on stand-alone selling prices for software licenses, cost plus applicable margin for services and established pricing for maintenance. The initial sale of software products generally requires significant production, modification or customization, such that the delivery of the software license and the related professional services required to implement the software represent one combined performance obligation that is satisfied over time based of hours worked (hours-based method). We are using hours worked on the project as the measure to determine progress toward completion as we believe it is the most appropriate metric to measure such progress. The software and services fees are generally billed to our clients on a milestone or date basis. The determination of the performance obligations and allocation of value for software license arrangements require significant judgement. We generally determine stand-alone selling prices using pricing calculations (which include regional market factors) for our software license fees and maintenance, and cost-plus margins for services. Additionally, our use of an hours-based method of accounting for software license and other professional services performance obligations that are satisfied over time requires estimates of total project revenues and costs, along with the expected hours necessary to complete a project. Changes in estimates as a result of additional information or experience on a project as work progresses are inherent characteristics of this method of revenue recognition as we are exposed to various business risks in completing these types of performance obligations. The estimation process to support our hours-based recognition method is more difficult for projects of greater length and/or complexity. The judgments and estimates made in this area could: (i) have a significant effect on revenues recognized in any period by changing the amount and/or the timing of the revenue recognized; and/or (ii) impact the expected profitability of a project, including whether an overall loss on an arrangement has occurred. To mitigate the inherent risks in using this hours-based method, we track our performance on projects and reevaluate the appropriateness of our estimates as part of our monthly accounting cycle. In certain instances, we sell software license volume upgrades, which provide our clients the right to use our software to process higher transaction volume levels. In these instances, we analyze the contract to determine if the volume upgrade is a separate performance obligation and if so, we recognize the value associated with the software license as revenue on the effective date of the volume upgrade. A portion of our professional services revenues are contracted separately (e.g., business consulting services, etc.). Such contracts can either be on a fixed-price or time-and-materials basis. Revenues from fixed-price, professional service contracts are recognized using an hours-based method, as these professional services represent a performance obligation that is satisfied over time. Revenues from professional services contracts billed on a time-and-materials basis are recognized as the services are performed. Prior to the adoption of ASC 606, we recognized revenue for our software arrangements under the guidelines of contract accounting as our software products required significant production, modification or customization and if we had VSOE of fair value for undelivered elements (e.g., maintenance), which we generally had, we would allocate a portion of the total arrangement fee to the undelivered element based on its VSOE of fair value, and the balance of the arrangement fee was recognized using the percentage-of-completion (“POC”) method of accounting. Maintenance Our maintenance revenue relates primarily to support of our software once it has been implemented. Maintenance revenues are recognized ratably over the software maintenance period as services are provided. Our maintenance consists primarily of client and product support, technical updates (e.g., bug fixes, etc.), and unspecified upgrades or enhancements to our software products. If specified upgrades or enhancements are offered in a contract, which is rare, they are accounted for as a separate performance obligation. Maintenance can be invoiced to our clients on a monthly, quarterly or annual basis. Transaction Price Allocated to the Remaining Performance Obligations As of June 30, 2018, our aggregate amount of the transaction price allocated to the remaining performance obligations is approximately $491 million, which is made up of fixed fee consideration and guaranteed minimums expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied). We expect to recognize approximately 80% of this amount by the end of 2020, with the remaining amount recognized by the end of 2028. We have excluded from this amount variable consideration expected to be recognized in the future related to performance obligations that are unsatisfied (a practical expedient allowed under ASC 606). The majority of our future revenue is related to our cloud and related solution client contracts that include variable consideration dependent upon a series of monthly volumes and/or daily usage of services and have contractual terms ending from 2019 through 2028. We have not disclosed transaction price allocation to remaining performance obligations or an explanation thereof of comparable amounts as of December 31, 2017 (a transitional practical expedient allowed under ASC 606). Disaggregation of Revenue In the following table, revenue is disaggregated by geographic region (using the location of the client as the basis of attributing revenues to the individual regions): Quarter Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Americas (principally the U.S.) $ 180,217 $ 162,835 $ 350,120 $ 327,972 Europe, Middle East, and Africa 21,977 17,817 42,411 35,031 Asia Pacific 10,839 12,061 22,206 22,180 Total revenues $ 213,033 $ 192,713 $ 414,737 $ 385,183 Billed and Unbilled Accounts Receivable. Billed accounts receivable represents our unconditional rights to consideration. Once invoiced, our payment terms are generally between 30-60 days, and rarely do we have contracts with financing arrangements. Unbilled accounts receivable represents our rights to consideration for work completed but not billed. Unbilled accounts receivable is transferred to billed accounts receivable when the rights become unconditional which is generally at the time of invoicing. The following table rolls forward our unbilled accounts receivable from December 31, 2017 to June 30, 2018 (in thousands): Unbilled Receivables Beginning Balance, December 31, 2017 $ 31,187 Cumulative effect adjustments 4,193 Reclassification - Adoption of ASC 606 (2,276 ) Beginning Balance, January 1, 2018 $ 33,104 Recognized during the period 111,549 Reclassified to receivables (104,913 ) Other (908 ) Ending Balance, June 30, 2018 $ 38,832 Deferred Revenue. Deferred revenue represents consideration received from clients in advance of services being performed. The following table rolls forward our deferred revenue from December 31, 2017 to June 30, 2018 (in thousands): Deferred Revenue Beginning Balance, December 31, 2017 $ (54,231 ) Cumulative effect adjustments 4,344 Reclassification - Adoption of ASC 606 2,276 Beginning Balance, January 1, 2018 $ (47,611 ) Revenue recognized that was included in deferred revenue at the beginning of the period 29,546 Consideration received in advance of services performed net of revenue recognized in the current period (31,747 ) Other 1,180 Ending Balance, June 30, 2018 $ (48,632 ) Cash and Cash Equivalents. We consider all highly liquid investments with original maturities of three months or less at the date of the purchase to be cash equivalents. As of June 30, 2018 and December 31, 2017, our cash equivalents consist primarily of institutional money market funds, commercial paper, and time deposits held at major banks. As of June 30, 2018 and December 31, 2017, we had $2.0 million and $4.2 million, respectively, of restricted cash that serves to collateralize outstanding letters of credit. This restricted cash is included in cash and cash equivalents in our Condensed Consolidated Balance Sheets (“Balance Sheets” or “Balance Sheet”). Short-term Investments and Other Financial Instruments . Our financial instruments as of June 30, 2018 and December 31, 2017 include cash and cash equivalents, short-term investments, accounts receivable, accounts payable, and debt. Because of their short maturities, the carrying amounts of cash equivalents, accounts receivable, and accounts payable approximate their fair value. Our short-term investments and certain of our cash equivalents are considered “available-for-sale” and are reported at fair value in our Balance Sheets, with unrealized gains and losses, net of the related income tax effect, excluded from earnings and reported in a separate component of stockholders’ equity. Realized and unrealized gains and losses were not material in any period presented. Primarily all short-term investments held by us as of June 30, 2018 and December 31, 2017 have contractual maturities of less than two years from the time of acquisition. Our short-term investments as of June 30, 2018 and December 31, 2017 consisted almost entirely of fixed income securities. Proceeds from the sale/maturity of short-term investments for the six months ended June 30, 2018 and 2017 were $116.9 million and $104.3 million, respectively. The following table represents the fair value hierarchy based upon three levels of inputs, of which Levels 1 and 2 are considered observable and Level 3 is unobservable, for our financial assets and liabilities measured at fair value (in thousands): June 30, 2018 December 31, 2017 Level 1 Level 2 Total Level 1 Level 2 Total Assets: Cash equivalents: Money market funds $ 7,450 $ — $ 7,450 $ 3,544 $ — $ 3,544 Commercial paper — 22,085 22,085 — 32,467 32,467 Short-term investments: Corporate debt securities — 53,345 53,345 — 124,182 124,182 U.S. government agency bonds — 1,542 1,542 — 1,547 1,547 Asset-backed securities — 11,806 11,806 — 13,388 13,388 Total $ 7,450 $ 88,778 $ 96,228 $ 3,544 $ 171,584 $ 175,128 Valuation inputs used to measure the fair values of our money market funds and corporate equity securities were derived from quoted market prices. The fair values of all other financial instruments are based upon pricing provided by third-party pricing services. These prices were derived from observable market inputs. We have chosen not to measure our debt at fair value, with changes recognized in earnings each reporting period. The following table indicates the carrying value (par value for convertible debt) and estimated fair value of our debt as of the indicated periods (in thousands): June 30, 2018 December 31, 2017 Carrying Fair Carrying Fair Value Value Value Value 2015 Credit Agreement (carrying value including current maturities) $ — $ — $ 120,000 $ 120,000 2018 Credit Agreement (carrying value including current maturities) 148,125 148,125 — — 2016 Convertible debt (par value) 230,000 242,363 230,000 251,850 The fair value for our credit agreement was estimated using a discounted cash flow methodology, while the fair value for our convertible debt was estimated based upon quoted market prices or recent sales activity, both of which are considered Level 2 inputs. See Note 4 for additional discussion regarding an amendment to our Credit Agreement. Other Accounting Pronouncements Adopted. In October 2016, the FASB issued ASU 2016-16, . This ASU requires entities to recognize at the transaction date the income tax consequences of intercompany asset transfers. This ASU is effective in annual and interim periods in fiscal years beginning after December 15, 2017, with early adoption permitted, and requires a modified retrospective transition method. We adopted this ASU in January 2018 and the adoption of this standard did not have a material impact on our Financial Statements. Accounting Pronouncement Issued But Not Yet Effective. In February 2016, the FASB issued ASU 2016-02, (Topic 842). This ASU requires lessees to recognize a lease liability and a right-to-use asset for all leases, including operating leases, with a term greater than twelve months on its balance sheet. This ASU is effective in annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. An entity may choose to adopt this ASU either retrospectively or prospectively as of the start of the first period for which it applies the standard. We are currently in the process of evaluating the impact this ASU will have on our Financial Statements. Based on our initial evaluations, we believe the adoption of this standard will have a material impact on our consolidated balance sheet.

Other Intangible Assets. As part of the adoption of ASC 606, at January 1, 2018, we reclassified our investment in client contracts and capitalized costs related to conversion/set-up activities from “client contracts” to “client contract costs” on our Balance Sheet. As of June 30, 2018, our intangible assets subject to ongoing amortization consist of acquired client contracts and software. As of June 30, 2018 and December 31, 2017, the carrying values of our other intangible assets were as follows (in thousands): June 30, 2018 December 31, 2017 Gross Gross Carrying Accumulated Net Carrying Accumulated Net Amount Amortization Amount Amount Amortization Amount Investments in client contracts $ - $ - $ - $ 26,616 $ (9,782 ) $ 16,834 Capitalized costs - - - 26,811 (10,039 ) 16,772 Acquired client contracts 120,971 (79,398 ) 41,573 87,308 (77,288 ) 10,020 Total client contracts 120,971 (79,398 ) 41,573 140,735 (97,109 ) 43,626 Software 144,936 (114,010 ) 30,926 135,892 (108,986 ) 26,906 Total intangible assets $ 265,907 $ (193,408 ) $ 72,499 $ 276,627 $ (206,095 ) $ 70,532 Other intangible assets as of June 30, 2018 include assets acquired in the Business Ink business acquisition (see Note 5). The total amortization expense related to other intangible assets for the second quarters of 2018 and 2017 were $4.8 million and $6.4 million, respectively, and for the six months ended June 30, 2018 and 2017 were $8.8 million and $13.3 million, respectively. Client Contract Costs . As of June 30, 2018, the carrying values of our contract cost assets, related to those contracts with a contractual term greater than one year, were as follows (in thousands): June 30, 2018 Gross Carrying Accumulated Net Amount Amortization Amount Client contract incentives (1) $ 26,766 $ (15,272 ) $ 11,494 Capitalized costs (2) 33,619 (14,744 ) 18,875 Capitalized commission fees (3) 6,074 (916 ) 5,158 Total client contract costs $ 66,459 $ (30,932 ) $ 35,527 The aggregate amortization related to our client contract costs include in our operations for the quarter and six months ended June 30, 2018 Quarter Ended Six Months Ended June 30, 2018 June 30, 2018 Client contract incentives (1) $ 2,764 $ 5,491 Capitalized costs (2) 2,442 4,837 Capitalized commission fees (3) 579 935 Total client contract costs $ 5,785 $ 11,263 (1) Client contract incentives consist principally of incentives provided to new or existing clients to convert their customer accounts to, or retain their customer’s account on, our outsourced solutions and are amortized ratably over the contract period to include renewal periods if applicable, which as of June 30, 2018, have termination dates that range from 2019 to 2025. The amortization of client contract incentives is reflected as a reduction in cloud and related solutions revenue in our Income Statement. (2) Capitalized costs are related to client conversion/set-up activities and direct material costs to fulfill long-term cloud-based or managed services arrangements. These costs are amortized over the contract period based on the transfer of goods or services to which the assets relate, which as of June 30, 2018 range from 2019 to 2023, and are included in cost of cloud and related solutions in our Income Statement. (3) Capitalized commission fees are incremental commissions paid as a result of obtaining a customer contract. These fees are amortized over the contract period based on the transfer of goods or services to which the assets relate, which as of June 30, 2018, range from 2019 to 2021, and are included in selling, general and administrative expenses on our Income Statement. Incremental commission fees incurred as a result of obtaining a customer contract are expensed when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less (a practical expedient allowed under ASC 606). These costs were not significant in the quarter and six months ended June 30, 2018 and are included in selling, general and administrative expenses.

On March 5, 2018, we entered into a new $350 million credit agreement (the “2018 Credit Agreement”) with a consortium of banks to replace the 2015 Credit Agreement. The 2018 Credit Agreement provides borrowings in the form of: (i) a $150 million aggregate principal five-year term loan (the “2018 Term Loan”); and (ii) a $200 million aggregate principal five-year revolving loan facility (the “2018 Revolver”). With the $150 million proceeds from the 2018 Term Loan, we repaid the outstanding $120 million balance of the term loan under the 2015 Credit Agreement, resulting in a net increase of available cash by $30 million, a portion of which was used to pay certain fees and expenses in connection with the refinancing, and the remainder of which will be used for general corporate purposes. The interest rates under the 2018 Credit Agreement are based upon our choice of an adjusted LIBOR rate plus an applicable margin of 1.50% - 2.50%, or an alternate base rate plus an applicable margin of 0.50% -1.50%, with the applicable margin, depending on our then-net secured total leverage ratio. We will pay a commitment fee of 0.200% - 0.375% of the average daily unused amount of the 2018 Revolver, with the commitment fee rate also dependent upon our then-net secured total leverage ratio. The 2018 Credit Agreement includes mandatory repayments of the aggregate principal amount of the 2018 Term Loan (payable quarterly) for the first, second, third, fourth, and fifth years, with the remaining principal balance due at maturity. The 2018 Credit Agreement has no prepayment penalties and requires mandatory repayments under certain circumstances, including: (i) asset sales or casualty proceeds; and (ii) proceeds of debt or preferred stock issuances. The 2018 Credit Agreement contains customary affirmative covenants. In addition, the 2018 Credit Agreement has customary negative covenants that places limits on our ability to: (i) incur additional indebtedness; (ii) create liens on its property; (iii) make investments; (iv) enter into mergers and consolidations; (v) sell assets; (vi) declare dividends or repurchase shares; (vii) engage in certain transactions with affiliates; and (viii) prepay certain indebtedness; and (ix) issue capital stock of subsidiaries. We must also meet certain financial covenants to include: (i) a maximum total leverage ratio; (ii) a maximum first-lien leverage ratio; and (iii) a minimum interest coverage ratio. In conjunction with the 2018 Credit Agreement, we entered into a security agreement in favor of Bank of America N.A, as collateral agent (the “Security Agreement”). Under the Security Agreement and 2018 Credit Agreement, certain of our domestic subsidiaries have guaranteed our obligations, and have pledged substantially all of our assets to secure the obligations under the 2018 Credit Agreement and such guarantees. During the six months ended June 30, 2018, we made $1.9 million of principal repayments on our 2018 Credit Agreement. As of June 30, 2018, our interest rate on the 2018 Term Loan is 3.83% (adjusted LIBOR plus 1.50% per annum), effective through September 28, 2018, and our commitment fee on the 2018 Revolver is 0.20%. As of June 30, 2018, we had no borrowing outstanding on our 2018 Revolver and had the entire $200.0 million available to us. In conjunction with the closing of the 2018 Credit Agreement, we incurred financing costs of $1.5 million. When combined with the remaining deferred financing costs of the 2015 Credit Agreement, financing costs of $2.8 million have been deferred and are being amortized to interest expense using the effective interest method over the related term of the 2018 Credit Agreement. Additionally, as certain lenders from the 2015 Credit Agreement chose not to participate in the 2018 Credit Agreement syndication group, we wrote-off $0.8 million of unamortized debt issuance costs and recognized a loss on extinguishment of that debt. Convertible Notes 2016 Convertible Notes. Upon conversion of the 2016 Convertible Notes, we will settle our conversion obligation by paying or delivering, as the case may be, cash, shares of our common stock, or a combination thereof, at our election. It is our current intent and policy to settle our conversion obligations as follows: (i) pay cash for 100% of the par value of the 2016 Convertible Notes that are converted; and (ii) to the extent the value of our conversion obligation exceeds the par value, we can satisfy the remaining conversion obligation in our common stock, cash or a combination thereof. The 2016 Convertible Notes will be convertible at the option of the note holders upon the satisfaction of specified conditions and during certain periods. During the period from, and including, December 15, 2021 to the close of business on the business day immediately preceding March 15, 2022 and on or after December 15, 2035, holders may convert all or any portion of their 2016 Convertible Notes at the conversion rate then in effect at any time regardless of these conditions. As a result of us increasing our quarterly dividend in June 2018 (see Note 10), the previous conversion rate for the 2016 Convertible Notes of 17.4951 shares of our common stock per $1,000 principal amount of the 2016 Convertible Notes, which is equivalent to an initial conversion price of approximately $57.16 per share of our common stock, has been adjusted to 17.5057 shares of our common stock per $1,000 principal amount of the 2016 Convertible Notes, which is equivalent to an initial conversion price of approximately $57.12 per share of our common stock. Holders may require us to repurchase the 2016 Convertible Notes for cash on each of March 15, 2022, March 15, 2026, and March 15, 2031, or upon the occurrence of a fundamental change (as defined in the 2016 Convertible Notes Indenture) in each case at a purchase price equal to the principal amount thereof plus accrued and unpaid interest. We may not redeem the 2016 Convertible Notes prior to March 20, 2020. On or after March 20, 2020, we may redeem for cash all or part of the 2016 Convertible Notes if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. On or after March 15, 2022, we may redeem for cash all or part of the 2016 Convertible Notes regardless of the sales price condition described in the preceding sentence. In each case, the redemption price will equal the principal amount of the 2016 Convertible Notes to be redeemed, plus accrued and unpaid interest. As of June 30, 2018, none of the conversion features have been achieved, and thus, the 2016 Convertible Notes are not convertible by the holders.

Business Combinations [Abstract]
Business Ink Acquisition	5. BUSINESS INK ACQUISITION On February 28, 2018, we acquired Business Ink for approximately $70 million in cash. Business Ink is a company based in Austin, Texas, with facilities in multiple locations. Business Ink provides outsourced, customized business communications services to the telecommunications, healthcare, financial services, utilities and government sectors across statements, email, mobile messaging and more. The acquisition extends the scale of our operations and platform capabilities, expands our customer base into new verticals, and further solidifies our customer communications footprint. The following table summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the date of acquisition (in thousands): Current assets $ 25,479 Fixed assets 13,337 Acquired client contracts 35,150 Acquired software 4,132 Goodwill 3,561 Non-current assets 148 Total assets acquired 81,807 Current liabilities (11,586 ) Non-current liabilities (256 ) Total liabilities assumed (11,842 ) Net assets acquired $ 69,965 The above estimated fair values of assets acquired and liabilities assumed are considered provisional and are based on the information that was available as of the date of the Business Ink acquisition to estimate the fair value of assets acquired and liabilities assumed. We believe that information provides a reasonable basis for estimating the fair values of assets acquired and liabilities assumed, but we are waiting for additional information necessary to finalize those fair values. Thus, the provisional measurements of fair value set forth above are subject to change. Such changes are not expected to be significant. During the second quarter of 2018, we made certain adjustments, primarily to increase the value of the acquired client contracts by $4.3 million. As a result of these adjustments, the amount allocated to goodwill decreased by $4.5 million. We expect to finalize the valuation and complete the purchase price allocation as soon as practicable, but not later than one year from the acquisition date. The Business Ink goodwill has been assigned to our one reportable segment. The estimated lives assigned to the acquired client contracts and the acquired software assets range from approximately four months to fifteen years (weighted-average life of thirteen years), and four years, respectively. Amortization expense related to these acquired intangible assets is recognized based upon the pattern in which the economic benefits of the acquired intangible assets are expected to be received. The Business Ink goodwill and acquired intangible assets are deductible for income tax purposes. The results of operations of Business Ink are included in the accompanying Condensed Consolidated Statements of Income for the period subsequent to the acquisition date. Pro forma information on our historical results of operations to reflect the acquisition of Business Ink is not presented as Business Ink’s results of operations during prior periods are not significant to our results of operations.

Restructuring and Reorganization Charges	6. RESTRUCTURING AND REORGANIZATION CHARGES During the second quarters of 2018 and 2017, we recorded restructuring and reorganization charges of $3.3 million and $2.7 million, respectively, and for the six months ended June 30, 2018 and 2017, we recorded restructuring and reorganization charges of $4.2 million and $3.0 million, respectively. Our restructuring activities during the six months ended June 30, 2018 were primarily made up of the following: • We reduced our workforce by approximately 40 employees as a result of organizational changes made to pursue global opportunities and efficiencies. As a result, we incurred restructuring charges related to involuntary terminations of $1.8 million. • We are in the process of closing one of our print facilities. As a result, we incurred restructuring charges related to involuntary terminations and the impairment of assets of $1.4 million. The activity in the business restructuring and reorganization reserves during the six months ended June 30, 2018 was as follows: Termination Facilities Benefits Abandonment Other Total January 1, 2018 balance $ 1,116 $ 3,032 $ — $ 4,148 Charged to expense during period 2,159 959 1,111 4,229 Cash payments (2,061 ) (1,168 ) — (3,229 ) Adjustment for asset impairment — — (1,001 ) (1,001 ) Other (71 ) 16 (110 ) (165 ) June 30, 2018 balance $ 1,143 $ 2,839 $ — $ 3,982

Commitments And Contingencies Disclosure [Abstract]
Commitments, Guarantees and Contingencies	8. COMMITMENTS, GUARANTEES AND CONTINGENCIES Warranties. We generally warrant that our solutions and related offerings will conform to published specifications, or to specifications provided in an individual client arrangement, as applicable. The typical warranty period is 90 days from the date of acceptance of the solution or offering. For certain service offerings we provide a limited warranty for the duration of the services provided. We generally warrant that services will be performed in a professional and workmanlike manner. The typical remedy for breach of warranty is to correct or replace any defective deliverable, and if not possible or practical, we will accept the return of the defective deliverable and refund the amount paid under the client arrangement that is allocable to the defective deliverable. Our contracts also generally contain limitation of damages provisions in an effort to reduce our exposure to monetary damages arising from breach of warranty claims. Historically, we have incurred minimal warranty costs, and as a result, do not maintain a warranty reserve. Product and Services Indemnifications. Our arrangements with our clients generally include an indemnification provision that will indemnify and defend a client in actions brought against the client that claim our products and/or services infringe upon a copyright, trade secret, or valid patent. Historically, we have not incurred any significant costs related to such indemnification claims, and as a result, do not maintain a reserve for such exposure. Claims for Company Non-performance. Our arrangements with our clients typically cap our liability for breach to a specified amount of the direct damages incurred by the client resulting from the breach. From time-to-time, these arrangements may also include provisions for possible liquidated damages or other financial remedies for our non-performance, or in the case of certain of our outsourced customer care and billing solutions, provisions for damages related to service level performance requirements. The service level performance requirements typically relate to system availability and timeliness of service delivery. Historically, we have not incurred significant costs associated with service level performance within our client contracts, and as a result, do not include estimates for potential credits or refunds related to service level performance in our contract consideration at the onset of the contract, but instead, account for credits or refunds as an adjustment to the transaction price of the contract as those events occur. Indemnifications Related to Officers and the Board of Directors. We have agreed to indemnify members of our Board of Directors (the “Board”) and certain of our officers if they are named or threatened to be named as a party to any proceeding by reason of the fact that they acted in such capacity. We maintain directors’ and officers’ (D&O) insurance coverage to protect against such losses. We have not historically incurred any losses related to these types of indemnifications, and are not aware of any pending or threatened actions or claims against any officer or member of our Board. As a result, we have not recorded any liabilities related to such indemnifications as of June 30, 2018. In addition, as a result of the insurance policy coverage, we believe these indemnification agreements are not significant to our results of operations. Legal Proceedings. From time-to-time, we are involved in litigation relating to claims arising out of our operations in the normal course of business. We are not presently a party to any material pending or threatened legal proceedings.

Earnings Per Share [Abstract]
Earnings Per Common Share	9. EARNINGS PER COMMON SHARE Basic and diluted earnings per common share (“EPS”) amounts are presented on the face of the accompanying Income Statements. No reconciliation of the basic and diluted EPS numerators is necessary as net income is used as the numerators for all periods presented. The reconciliation of the basic and diluted EPS denominators related to the common shares is included in the following table (in thousands): Quarter Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Basic weighted-average common shares 32,589 32,572 32,558 32,294 Dilutive effect of restricted common stock 156 424 274 501 Dilutive effect of Stock Warrants 163 — 173 — Diluted weighted-average common shares 32,908 32,996 33,005 32,795 The Convertible Notes have a dilutive effect only in those quarterly periods in which our average stock price exceeds the current effective conversion price (see Note 4). The Stock Warrants have a dilutive effect only in those quarterly periods in which our average stock price exceeds the exercise price of $26.68 per warrant (under the treasury stock method), and are not subject to performance vesting conditions (see Note 10). Potentially dilutive common shares related to non-participating unvested restricted stock excluded from the computation of diluted EPS, as the effect was antidilutive, were not material in any period presented.

Stockholders Equity Note [Abstract]
Stockholders' Equity and Equity Compensation Plans	10. STOCKHOLDERS’ EQUITY AND EQUITY COMPENSATION PLANS Stock Repurchase Program. We currently have a stock repurchase program, approved by our Board, authorizing us to repurchase our common stock from time-to-time as market and business conditions warrant (the “Stock Repurchase Program”). During the six months ended June 30, 2018 and 2017 we repurchased 0.3 million shares of our common stock for $11.3 million (weighted-average price of $44.25 per share) and 0.3 million shares of our common stock for $10.5 million (weighted-average price of $41.00 per share), respectively, under a SEC Rule 10b5-1 Plan. As of June 30, 2018, the total remaining number of shares available for repurchase under the Stock Repurchase Program totaled 6.0 million shares. Stock Repurchases for Tax Withholdings. In addition to the above-mentioned stock repurchases, during the six months ended June 30, 2018 and 2017, we repurchased and then cancelled 0.1 million shares of common stock for $7.0 million and 0.2 million shares of common stock for $6.3 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted common stock under our stock incentive plans. Stock Incentive Plan. In May 2018, our stockholders approved an increase of 2.7 million shares authorized for issuance under the 2005 Stock Incentive Plan, from 18.7 million shares to 21.4 million shares. Cash During the second quarter of 2018, the Board approved a quarterly cash dividend of $0.21 per share of common stock, totaling $7.1 million. During the second quarter of 2017, the Board approved a quarterly cash dividend of $0.1975 per share of common stock, totaling $6.7 million. Dividends declared for the six months ended June 30, 2018 and 2017 totaled $14.2 million and $13.4 million, respectively. Warrants . In 2014, in conjunction with the execution of an amendment to our current agreement with Comcast, we issued stock warrants (the “Warrant Agreement”) for the right to purchase up to approximately 2.9 million shares of our common stock (the “Stock Warrants”) as an additional incentive for Comcast to convert customer accounts onto our Advanced Convergent Platform based on various milestones. The Stock Warrants have a 10-year term and an exercise price of $26.68 per warrant. Upon vesting, the Stock Warrants are recorded as a client contract incentive asset with the corresponding offset to stockholders’ equity. The client contract incentive asset related to the Stock Warrants is amortized as a reduction in cloud and related solutions revenues over the remaining term of the Comcast amended agreement. As of June 30, 2018 and December 31, 2017, we recorded a client contract incentive asset related to these Stock Warrants of $25.1 million as of both periods and have recorded accumulated amortization related to these Stock Warrants of $14.5 million and $9.2 million, respectively. The remaining unvested Stock Warrants will be accounted for as client contract incentive assets in the period the performance conditions necessary for vesting have been met. As of June 30, 2018, approximately 1.4 million Stock Warrants remain issued, of which 0.4 million were vested. Stock-Based Awards. A summary of our unvested restricted common stock activity during the quarter and six months ended June 30, 2018 is as follows (shares in thousands): Quarter Ended Six Months Ended June 30, 2018 June 30, 2018 Shares Weighted- Average Grant Date Fair Value Shares Weighted- Average Grant Date Fair Value Unvested awards, beginning 1,216 $ 41.48 1,222 $ 36.84 Awards granted 39 43.80 489 46.75 Awards forfeited/cancelled (21 ) 42.35 (79 ) 40.18 Awards vested (45 ) 38.49 (443 ) 34.25 Unvested awards, ending 1,189 $ 41.67 1,189 $ 41.67 Included in the awards granted during 2018 The other restricted common stock shares granted during the six months ended June 30, 2018 We recorded stock-based compensation expense for the second quarters of 2018 and 2017 of $5.6 million and $6.0 million, respectively, and for the six months ended June 30, 2018 and 2017 of $10.2 million and $11.6 million, respectively.

Use of Estimates in Preparation of Our Financial Statements	Use of Estimates in Preparation of Financial Statements. The preparation of the accompanying Financial Statements in conformity with GAAP 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 our Financial Statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Revenue	Revenue . We adopted Topic 606 (“ASC 606”) as of January 1, 2018 using the cumulative effect method and have applied ASC 606 to all contracts with clients that had not been completed as of the date of initial application. In conjunction with the adoption of ASC 606, we recorded a cumulative adjustment increasing beginning retained earnings (net of tax) by approximately $7 million, primarily related to contracts that we were previously required to defer revenue as we did not have vendor specific objective evidence (“VSOE”) of fair value for certain undelivered elements. Since we adopted ASC 606 using the cumulative effect method, comparative information in our Financial Statements has not been adjusted and continues to be as previously reported. The following tables summarize the impacts of adopting ASC 606 on our Financial Statements as of and for the quarter and six months ended June 30, 2018 (in thousands, except per share amounts): As of June 30, 2018 Condensed Balance Sheet As Reported Adjustments Balances without adoption of ASC 606 Unbilled trade accounts receivable $ 38,832 $ (614 ) $ 38,218 Other current assets 38,185 3,670 41,855 Client contracts, net of amortization - 69,125 69,125 Acquired client contracts, net of amortization 41,573 (41,573 ) - Client contract costs, net of amortization 35,527 (35,527 ) - Other non-current assets 7,012 4,305 11,317 Other assets 766,102 - 766,102 Total assets (1) $ 927,231 $ (614 ) $ 926,617 Deferred revenue $ 48,632 $ 3,218 $ 51,850 Deferred income taxes 9,162 (179 ) 8,983 Other liabilities 519,577 - 519,577 Total liabilities 577,371 3,039 580,410 Accumulated earnings 772,071 (3,653 ) 768,418 Other stockholders' equity (422,211 ) - (422,211 ) Total stockholders' equity 349,860 (3,653 ) 346,207 Total stockholders' equity and liabilities $ 927,231 $ (614 ) $ 926,617 (1) See Note 3 for further discussion related to the reclassification of our client contracts and client contract costs.

Costs associated with these products were also reclassified to cost of cloud solution services in the quarter and six months ended June 30, 2018. Six Months Ended June 30, 2018 Condensed Statement of Cash Flows As Reported Adjustments Balances without adoption of ASC 606 Net income $ 29,131 $ 916 $ 30,047 Adjustments to reconcile net income to net cash provided by operating activities - Amortization 20,957 (2,002 ) 18,955 Deferred income taxes 4,944 374 5,318 Other 21,691 - 21,691 Changes in operating assets and liabilities: Other current and non-current assets (13,995 ) 5,349 (8,646 ) Deferred revenue 799 (1,126 ) (327 ) Other (37,313 ) - (37,313 ) Net cash provided by operating activities 26,214 3,511 29,725 Cash flows from investing activities: Acquisition of and investments in client contracts - (3,511 ) (3,511 ) Other (22,830 ) - (22,830 ) Net cash used in investing activities (22,830 ) (3,511 ) (26,341 ) Net cash used in financing activities (4,925 ) - (4,925 ) Effect of exchange rate fluctuations on cash (1,031 ) - (1,031 ) Net decrease cash and cash equivalents (2,572 ) - (2,572 ) Cash and cash equivalents, beginning of period 122,243 - 122,243 Cash and cash equivalents, end of period $ 119,671 $ - $ 119,671 As a result of adopting ASC 606, we have changed our accounting policies for revenue recognition as discussed in more detail below. In summary, our revenue from client contracts is primarily related to our cloud and related solutions and, to a lesser degree, software and service and related maintenance arrangements, and is measured based on consideration specified within each of our contracts, excluding sales incentives and amounts collected on behalf of third parties, if any. We account for various products and services separately if they are distinct. A product or service, or group of products or services, is distinct if it is separately identifiable from other items in the context of the contract and if our client can benefit from the product or service on their own or with other resources that are readily available to that client. We recognize revenue when we satisfy our performance obligations by transferring control over a particular product or service, or group of products or services, to our clients, as described in more detail below. Taxes assessed on our products and services based on governmental authorities at the time of invoicing are excluded from our revenue.
Transaction Price Allocated to the Remaining Performance Obligations	Transaction Price Allocated to the Remaining Performance Obligations As of June 30, 2018, our aggregate amount of the transaction price allocated to the remaining performance obligations is approximately $491 million, which is made up of fixed fee consideration and guaranteed minimums expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied). We expect to recognize approximately 80% of this amount by the end of 2020, with the remaining amount recognized by the end of 2028. We have excluded from this amount variable consideration expected to be recognized in the future related to performance obligations that are unsatisfied (a practical expedient allowed under ASC 606). The majority of our future revenue is related to our cloud and related solution client contracts that include variable consideration dependent upon a series of monthly volumes and/or daily usage of services and have contractual terms ending from 2019 through 2028. We have not disclosed transaction price allocation to remaining performance obligations or an explanation thereof of comparable amounts as of December 31, 2017 (a transitional practical expedient allowed under ASC 606).
Disaggregation of Revenue	Disaggregation of Revenue In the following table, revenue is disaggregated by geographic region (using the location of the client as the basis of attributing revenues to the individual regions): Quarter Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Americas (principally the U.S.) $ 180,217 $ 162,835 $ 350,120 $ 327,972 Europe, Middle East, and Africa 21,977 17,817 42,411 35,031 Asia Pacific 10,839 12,061 22,206 22,180 Total revenues $ 213,033 $ 192,713 $ 414,737 $ 385,183
Billed and Unbilled Accounts Receivable	Billed and Unbilled Accounts Receivable. Billed accounts receivable represents our unconditional rights to consideration. Once invoiced, our payment terms are generally between 30-60 days, and rarely do we have contracts with financing arrangements. Unbilled accounts receivable represents our rights to consideration for work completed but not billed. Unbilled accounts receivable is transferred to billed accounts receivable when the rights become unconditional which is generally at the time of invoicing. The following table rolls forward our unbilled accounts receivable from December 31, 2017 to June 30, 2018 (in thousands): Unbilled Receivables Beginning Balance, December 31, 2017 $ 31,187 Cumulative effect adjustments 4,193 Reclassification - Adoption of ASC 606 (2,276 ) Beginning Balance, January 1, 2018 $ 33,104 Recognized during the period 111,549 Reclassified to receivables (104,913 ) Other (908 ) Ending Balance, June 30, 2018 $ 38,832
Deferred Revenue	Deferred Revenue. Deferred revenue represents consideration received from clients in advance of services being performed. The following table rolls forward our deferred revenue from December 31, 2017 to June 30, 2018 (in thousands): Deferred Revenue Beginning Balance, December 31, 2017 $ (54,231 ) Cumulative effect adjustments 4,344 Reclassification - Adoption of ASC 606 2,276 Beginning Balance, January 1, 2018 $ (47,611 ) Revenue recognized that was included in deferred revenue at the beginning of the period 29,546 Consideration received in advance of services performed net of revenue recognized in the current period (31,747 ) Other 1,180 Ending Balance, June 30, 2018 $ (48,632 )
Cash and Cash Equivalents	Cash and Cash Equivalents. We consider all highly liquid investments with original maturities of three months or less at the date of the purchase to be cash equivalents. As of June 30, 2018 and December 31, 2017, our cash equivalents consist primarily of institutional money market funds, commercial paper, and time deposits held at major banks. As of June 30, 2018 and December 31, 2017, we had $2.0 million and $4.2 million, respectively, of restricted cash that serves to collateralize outstanding letters of credit. This restricted cash is included in cash and cash equivalents in our Condensed Consolidated Balance Sheets (“Balance Sheets” or “Balance Sheet”).
Short-term Investments and Other Financial Instruments	Short-term Investments and Other Financial Instruments . Our financial instruments as of June 30, 2018 and December 31, 2017 include cash and cash equivalents, short-term investments, accounts receivable, accounts payable, and debt. Because of their short maturities, the carrying amounts of cash equivalents, accounts receivable, and accounts payable approximate their fair value. Our short-term investments and certain of our cash equivalents are considered “available-for-sale” and are reported at fair value in our Balance Sheets, with unrealized gains and losses, net of the related income tax effect, excluded from earnings and reported in a separate component of stockholders’ equity. Realized and unrealized gains and losses were not material in any period presented. Primarily all short-term investments held by us as of June 30, 2018 and December 31, 2017 have contractual maturities of less than two years from the time of acquisition. Our short-term investments as of June 30, 2018 and December 31, 2017 consisted almost entirely of fixed income securities. Proceeds from the sale/maturity of short-term investments for the six months ended June 30, 2018 and 2017 were $116.9 million and $104.3 million, respectively. The following table represents the fair value hierarchy based upon three levels of inputs, of which Levels 1 and 2 are considered observable and Level 3 is unobservable, for our financial assets and liabilities measured at fair value (in thousands): June 30, 2018 December 31, 2017 Level 1 Level 2 Total Level 1 Level 2 Total Assets: Cash equivalents: Money market funds $ 7,450 $ — $ 7,450 $ 3,544 $ — $ 3,544 Commercial paper — 22,085 22,085 — 32,467 32,467 Short-term investments: Corporate debt securities — 53,345 53,345 — 124,182 124,182 U.S. government agency bonds — 1,542 1,542 — 1,547 1,547 Asset-backed securities — 11,806 11,806 — 13,388 13,388 Total $ 7,450 $ 88,778 $ 96,228 $ 3,544 $ 171,584 $ 175,128 Valuation inputs used to measure the fair values of our money market funds and corporate equity securities were derived from quoted market prices. The fair values of all other financial instruments are based upon pricing provided by third-party pricing services. These prices were derived from observable market inputs. We have chosen not to measure our debt at fair value, with changes recognized in earnings each reporting period. The following table indicates the carrying value (par value for convertible debt) and estimated fair value of our debt as of the indicated periods (in thousands): June 30, 2018 December 31, 2017 Carrying Fair Carrying Fair Value Value Value Value 2015 Credit Agreement (carrying value including current maturities) $ — $ — $ 120,000 $ 120,000 2018 Credit Agreement (carrying value including current maturities) 148,125 148,125 — — 2016 Convertible debt (par value) 230,000 242,363 230,000 251,850 The fair value for our credit agreement was estimated using a discounted cash flow methodology, while the fair value for our convertible debt was estimated based upon quoted market prices or recent sales activity, both of which are considered Level 2 inputs. See Note 4 for additional discussion regarding an amendment to our Credit Agreement.
Other Accounting Pronouncements Adopted
Accounting Pronouncements	Other Accounting Pronouncements Adopted. In October 2016, the FASB issued ASU 2016-16, . This ASU requires entities to recognize at the transaction date the income tax consequences of intercompany asset transfers. This ASU is effective in annual and interim periods in fiscal years beginning after December 15, 2017, with early adoption permitted, and requires a modified retrospective transition method. We adopted this ASU in January 2018 and the adoption of this standard did not have a material impact on our Financial Statements.
Accounting Pronouncements Issued But Not Yet Effective
Accounting Pronouncements	Accounting Pronouncement Issued But Not Yet Effective. In February 2016, the FASB issued ASU 2016-02, (Topic 842). This ASU requires lessees to recognize a lease liability and a right-to-use asset for all leases, including operating leases, with a term greater than twelve months on its balance sheet. This ASU is effective in annual and interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted. An entity may choose to adopt this ASU either retrospectively or prospectively as of the start of the first period for which it applies the standard. We are currently in the process of evaluating the impact this ASU will have on our Financial Statements. Based on our initial evaluations, we believe the adoption of this standard will have a material impact on our consolidated balance sheet.
Cloud and Related Solutions Revenue
Revenue	Cloud and Related Solutions. Our cloud and related solutions revenue relates to: (i) our software-as-a-service (“SaaS”), cloud-based, revenue management and content monetization solutions, and various related ancillary services; and (ii) our managed services offering in which we operate software solutions (primarily our software solutions) on behalf of our clients. We contract for our cloud-based solutions using long-term arrangements whose terms have typically ranged from three to five years. The long-term cloud-based arrangements include a series of multiple services delivered daily or monthly, to include such things as: (i) revenue billing and customer communications management services; (ii) business support services (e.g., workforce management tools, consumer credit verifications, etc.); (iii) content monetization and delivery functions; and (iv) customer statement invoice printing and mailing services. The fees for these services typically are billed to our clients monthly based upon actual monthly volumes and/or usage of services (e.g., the number of client customers maintained on our systems, the number of transactions processed on our systems, and/or the quantity and content of the monthly statements and mailings processed through our systems). For cloud-based solution contracts, the total contract consideration (including impacts of discounts or incentives) is primarily variable dependent upon actual monthly volumes and/or usage of services; however, these contracts can also include ancillary fixed consideration in the form of one-time, monthly or annual fees. Although there may be multiple performance obligations, there is generally no allocation of value between the individual performance obligations as all are considered cloud and related solutions revenues that are recognized based on activities performed in each daily or monthly period. We contract for managed services solutions using long-term arrangements whose terms have typically ranged from three to five years. Under managed services agreements, we may operate software products (primarily our software solutions) on behalf of our clients: (i) out of a client’s data center; (ii) out of a data center we own and operate; or (iii) out of a third-party data center we contract with for such services. Managed services can also include us providing other services, such as transitional services, fulfillment, remittance processing, operational consulting, back office, and end user billing services. The fees for these services typically are billed to our clients monthly on a fixed schedule. For managed services contracts, the total contract consideration is typically a fixed fee, but these contracts may also have variable fee components. Unless managed services are included with a software license contract (as discussed further below), there is generally only one performance obligation and revenue is recognized for these arrangements on a ratable basis as the services are performed. Fees related to set-up or implementation activities for both cloud-based solution and managed services contracts are deferred and recognized ratably over the related service period to which the activities relate. Due to the significance of variable consideration, number of products/services, complex pricing structures and long-term nature of these types of contracts, the judgments and estimates made in this area could have a significant effect on the amount and timing of revenues recognized in any period. Prior to the adoption of ASC 606, we recognized revenue related to our cloud and related solutions contracts on a monthly basis as we provided the services. The adoption of ASC 606 did not result in any significant changes to the timing of revenue recognition related to these contracts.
Software and Services Revenue
Revenue	Software and Services. Our software and services revenue relates primarily to: (i) software license sales on either a perpetual or term license basis; and (ii) professional services to implement the software. Our software and services contracts are often contracted in bundled arrangements that include not only the software license and related implementation services, but can also include maintenance, managed services and/or additional professional services. For our software arrangements, the total contract consideration is allocated between the separate performance obligations based on stand-alone selling prices for software licenses, cost plus applicable margin for services and established pricing for maintenance. The initial sale of software products generally requires significant production, modification or customization, such that the delivery of the software license and the related professional services required to implement the software represent one combined performance obligation that is satisfied over time based of hours worked (hours-based method). We are using hours worked on the project as the measure to determine progress toward completion as we believe it is the most appropriate metric to measure such progress. The software and services fees are generally billed to our clients on a milestone or date basis. The determination of the performance obligations and allocation of value for software license arrangements require significant judgement. We generally determine stand-alone selling prices using pricing calculations (which include regional market factors) for our software license fees and maintenance, and cost-plus margins for services. Additionally, our use of an hours-based method of accounting for software license and other professional services performance obligations that are satisfied over time requires estimates of total project revenues and costs, along with the expected hours necessary to complete a project. Changes in estimates as a result of additional information or experience on a project as work progresses are inherent characteristics of this method of revenue recognition as we are exposed to various business risks in completing these types of performance obligations. The estimation process to support our hours-based recognition method is more difficult for projects of greater length and/or complexity. The judgments and estimates made in this area could: (i) have a significant effect on revenues recognized in any period by changing the amount and/or the timing of the revenue recognized; and/or (ii) impact the expected profitability of a project, including whether an overall loss on an arrangement has occurred. To mitigate the inherent risks in using this hours-based method, we track our performance on projects and reevaluate the appropriateness of our estimates as part of our monthly accounting cycle. In certain instances, we sell software license volume upgrades, which provide our clients the right to use our software to process higher transaction volume levels. In these instances, we analyze the contract to determine if the volume upgrade is a separate performance obligation and if so, we recognize the value associated with the software license as revenue on the effective date of the volume upgrade. A portion of our professional services revenues are contracted separately (e.g., business consulting services, etc.). Such contracts can either be on a fixed-price or time-and-materials basis. Revenues from fixed-price, professional service contracts are recognized using an hours-based method, as these professional services represent a performance obligation that is satisfied over time. Revenues from professional services contracts billed on a time-and-materials basis are recognized as the services are performed. Prior to the adoption of ASC 606, we recognized revenue for our software arrangements under the guidelines of contract accounting as our software products required significant production, modification or customization and if we had VSOE of fair value for undelivered elements (e.g., maintenance), which we generally had, we would allocate a portion of the total arrangement fee to the undelivered element based on its VSOE of fair value, and the balance of the arrangement fee was recognized using the percentage-of-completion (“POC”) method of accounting.
Maintenance Revenue
Revenue	Maintenance Our maintenance revenue relates primarily to support of our software once it has been implemented. Maintenance revenues are recognized ratably over the software maintenance period as services are provided. Our maintenance consists primarily of client and product support, technical updates (e.g., bug fixes, etc.), and unspecified upgrades or enhancements to our software products. If specified upgrades or enhancements are offered in a contract, which is rare, they are accounted for as a separate performance obligation. Maintenance can be invoiced to our clients on a monthly, quarterly or annual basis.

The amortization of client contract incentives is reflected as a reduction in cloud and related solutions revenue in our Income Statement. (2) Capitalized costs are related to client conversion/set-up activities and direct material costs to fulfill long-term cloud-based or managed services arrangements. These costs are amortized over the contract period based on the transfer of goods or services to which the assets relate, which as of June 30, 2018 range from 2019 to 2023, and are included in cost of cloud and related solutions in our Income Statement. (3) Capitalized commission fees are incremental commissions paid as a result of obtaining a customer contract. These fees are amortized over the contract period based on the transfer of goods or services to which the assets relate, which as of June 30, 2018, range from 2019 to 2021, and are included in selling, general and administrative expenses on our Income Statement. Incremental commission fees incurred as a result of obtaining a customer contract are expensed when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less (a practical expedient allowed under ASC 606). These costs were not significant in the quarter and six months ended June 30, 2018 and are included in selling, general and administrative expenses.
