Organization Consolidation And Presentation Of Financial Statements [Abstract]
General	1. GENERAL We have prepared the accompanying unaudited condensed consolidated financial statements as of September 30, 2019 and December 31, 2018, and for the quarters and nine months ended September 30, 2019 and 2018, 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, 2018 (our “2018 10-K”), filed with the SEC. The results of operations for the quarter and nine months ended September 30, 2019 are not necessarily indicative of the expected results for the entire year ending December 31, 2019.

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 U.S. 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. Revenues. The majority of our future revenues 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. Our client contracts may also include guaranteed minimums and fixed monthly or annual fees. As of September 30, 2019, our aggregate amount of the transaction price allocated to the remaining performance obligations is approximately $454 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 85% of this amount by the end of 2021, 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. The nature, amount, timing and uncertainty of our revenues and how revenues and cash flows are affected by economic factors is most appropriately depicted by type of revenues and by geographic region (using the location of the client as the basis of attributing revenues to the individual regions) as follows (in thousands): Quarter Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Cloud and related solutions $ 224,347 $ 186,473 $ 666,120 $ 551,390 Software and services 14,406 14,283 39,607 39,573 Maintenance 12,661 12,299 36,336 36,829 Total revenues $ 251,414 $ 213,055 $ 742,063 $ 627,792 Quarter Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Americas (principally the U.S.) $ 218,694 $ 180,489 $ 643,814 $ 530,609 Europe, Middle East, and Africa 23,284 21,723 70,516 64,135 Asia Pacific 9,436 10,843 27,733 33,048 Total revenues $ 251,414 $ 213,055 $ 742,063 $ 627,792 Deferred revenue recognized during the quarter and nine months ended September 30, 2019 was $5.7 million and $35.5 million, respectively. 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 September 30, 2019 and December 31, 2018, our cash equivalents consist primarily of institutional money market funds, commercial paper, and time deposits held at major banks. As of September 30, 2019 and December 31, 2018, we had $2.8 million and $3.0 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 September 30, 2019 and December 31, 2018 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 September 30, 2019 and December 31, 2018 have contractual maturities of less than two years from the time of acquisition. Our short-term investments as of September 30, 2019 and December 31, 2018 consisted almost entirely of fixed income securities. Proceeds from the sale/maturity of short-term investments for the nine months ended September 30, 2019 and 2018 were $38.0 million and $190.5 million, respectively. Our short-term investments as of September 30, 2019 and December 31, 2018 were $11.3 million and $23.6 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 measured at fair value (in thousands): September 30, 2019 December 31, 2018 Level 1 Level 2 Total Level 1 Level 2 Total Cash equivalents: Money market funds $ 8,564 $ — $ 8,564 $ 4,392 $ — $ 4,392 Commercial paper — 2,794 2,794 — 9,078 9,078 Short-term investments: Corporate debt securities — 5,018 5,018 — 16,357 16,357 U.S. government agency bonds — 2,904 2,904 — 3,724 3,724 Asset-backed securities — 3,415 3,415 — 3,522 3,522 Total $ 8,564 $ 14,131 $ 22,695 $ 4,392 $ 32,681 $ 37,073 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): September 30, 2019 December 31, 2018 Carrying Fair Carrying Fair Value Value Value Value 2018 Credit Agreement (carrying value including current maturities) $ 138,750 $ 138,750 $ 144,375 $ 144,375 2016 Convertible debt (par value) 230,000 261,050 230,000 228,275 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. Equity Method Investment. During the nine months ended September 30, 2019, we made an additional $4 million investment in a payment technology and services company that enables omni-channel digital payments in Latin America. As of September 30, 2019, we held an 8% noncontrolling interest with a carrying value of $6.6 million. Accounting Pronouncements Adopted. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU requires lessees to recognize a right-of-use asset and lease liability for all leases, including operating leases, with a term greater than twelve months on its balance sheet. This ASU is effective for annual and interim periods beginning after December 31, 2018. An entity is required to use a modified retrospective transition approach, but may choose to use either the effective date or the beginning of the earliest comparative period presented in its financial statements as of the date of initial application. We adopted this ASU in January 2019, utilizing the effective date method of transition. Since we adopted this ASU utilizing the effective date method, prior period information in our Financial Statements has not been adjusted and continues to be as previously reported. We elected the package of practical expedients permitted under the transition guidance within the new standard. Additionally, we updated our polices to align with the new accounting guidance and our processes to ensure that we properly account for new, existing, and modifications to leases subsequent to the adoption of the ASU. In conjunction with the adoption of this ASU we recorded additional assets and liabilities of approximately $80 million related to the right-of-use assets and lease liabilities, and have included the amortization of the right-of-use-assets and the accretion and payments of lease liabilities in the changes in other current and non-current assets and liabilities and in the changes in trade accounts payable and accrued liabilities, respectively, on our Statement of Cash Flows.

As of September 30, 2019, our interest rate on the 2018 Term Loan is 3.60% (adjusted LIBOR plus 1.50% per annum), effective through December 2019, and our commitment fee on the unused $200 million aggregate principal five-year revolving loan facility (the “2018 Revolver”) is 0.20%. As of September 30, 2019, we had no borrowings outstanding on our 2018 Revolver and had the entire $200.0 million available to us. 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. If the LIBOR rate is no longer available, then our interest rate under the Credit Agreement will be determined by the alternate base rate plus an applicable margin as discussed above. 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 cash, shares of our common stock, or a combination thereof, at our election. 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 our quarterly dividend in September 2019 (see Note 8), the previous conversion rate for the 2016 Convertible Notes of 17.5604 shares of our common stock per $1,000 principal amount of the 2016 Convertible Notes, which is equivalent to an initial conversion price of $56.95 per share of our common stock, has been adjusted to 17.5727 shares of our common stock per $1,000 principal amount of the 2016 Convertible Notes, which is equivalent to an initial conversion price of $56.91 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 September 30, 2019, none of the conversion features have been achieved, and thus, the 2016 Convertible Notes are not convertible by the holders.

Leases

Leases [Abstract]
Leases	5. LEASES We have operating leases for: (i) real estate which include both office space and statement production and mailing facilities; (ii) our outsourced data center environment; and (iii) operating equipment. Our leases have remaining terms of up to eight years, some of which include options to extend the leases for up to an additional ten years. For leases commencing prior to 2019, we used the noncancelable term to calculate the related right-of-use asset and corresponding lease liability. The exercise of lease renewal options is at our sole discretion. Additionally, certain of our leases include payments that are adjusted periodically for inflation. We have made an accounting policy election not to recognize on our balance sheet, leases with an initial term of twelve months or less, for any class of underlying asset. We have also made an election for real estate leases beginning in 2019 and later, not to separate the lease and non-lease components, but rather account for the entire arrangement as a single lease component (a practical expedient allowed under ASC 842). For our outsourced data center environment agreement, we have concluded that there are lease and non-lease components, and have allocated the consideration in the agreement on a relative stand-alone price basis. Due to the significant assumptions and judgements required in accounting for leases (to include whether a contract contains a lease, the allocation of the consideration, and the determination of the discount rate), the judgements and estimates made could have a significant effect on the amount of assets and liabilities recognized. We sublease certain of our leased real estate to third parties. These subleases have remaining lease terms of up to four years and certain subleases have renewal terms that can extend the lease for up to an additional two years. The components of lease expense were as follows (in thousands): Quarter Ended Nine Months Ended September 30, 2019 September 30, 2019 Operating lease expense $ 6,752 $ 17,915 Variable lease expense 1,328 3,535 Short-term lease expense 147 438 Sublease income (441 ) (1,274 ) Total net lease expense $ 7,786 $ 20,614 Other information related to leases was as follows (in thousands, except term and discount rate): Nine Months Ended September 30, 2019 Supplemental Cash Flows Information: Cash paid for amounts included in the measurement of operating lease liabilities $ 17,250 Right-of-use assets obtained in exchange for new operating lease liabilities 26,277 Weighted-average remaining lease term - operating leases 57 months Weighted-average discount rate - operating leases 4.40 % Future minimum lease payments under non-cancelable leases as of September 30, 2019 were as follows (in thousands): 2019 (excluding the nine months ended September 30, 2019) $ 7,960 2020 25,273 2021 25,146 2022 18,960 2023 12,504 Thereafter 21,898 Total future minimum lease payments (1) 111,741 Less: Interest (2) (12,279 ) Total $ 99,462 Current operating lease liabilities $ 22,888 Non-current operating lease liabilities 76,574 Total $ 99,462 (1) For leases commencing prior to 2019, minimum lease payments exclude payments for real estate taxes and non-lease components. (2) We used our in-country, currency adjusted incremental borrowing rate for the discount rate for the leases at adoption date, and will use the same approach for all leases commencing thereafter. As of September 30, 2019, we have one operating lease for office space that has not yet commenced of approximately $23 million. This operating lease will commence during 2020 with a lease term through 2031. Future minimum lease payments under non-cancelable leases as of December 31, 2018 were as follows: 2019 – $16.6 million; 2020 – $14.1 million; 2021 – $13.1 million; 2022 – $11.5 million; 2023 – $9.6 million; and thereafter – $14.7 million.

Commitments And Contingencies Disclosure [Abstract]
Commitments, Guarantees and Contingencies	6. 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 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 and contractual 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 contract consideration 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 September 30, 2019 . In addition, as a result of the insurance policy coverage, we believe these indemnification agreements are not significant to our results of operations. Prior Year Acquisition. On October 1, 2018, we acquired Forte, a leading provider of advanced payment solutions headquartered in Allen, Texas. We acquired 100% of the equity of Forte for a purchase price of approximately $93 million, (approximately $85 million, excluding cash acquired), of which approximately $13 million of the purchase price was held back subject to certain tax filings, and was paid in July 2019. The purchase agreement also includes provisions for $18.8 million of potential future earn-out payments over a four-year measurement period. The earn-out payments are tied to performance-based goals and a defined service period by the eligible recipients, and are therefore accounted for as post-acquisition compensation. As of September 30, 2019, we have accrued $2.5 million related to the potential earn-out payments. 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.

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 8). 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 and Equity Compensation Plans	8. 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 third quarters of 2019 and 2018 we repurchased approximately 92,000 shares of our common stock for $4.7 million (weighted-average price of $51.09 per share) and approximately 138,000 shares of our common stock for $5.5 million (weighted-average price of $39.87 per share), respectively, and during the nine months ended September 30, 2019 and 2018, we repurchased approximately 485,000 shares of our common stock for $20.6 million (weighted-average price of $42.37 per share) and approximately 395,000 shares of our common stock for $16.9 million (weighted-average price of $42.71 per share), respectively, under a SEC Rule 10b5-1 Plan. As of September 30, 2019, the total remaining number of shares available for repurchase under the Stock Repurchase Program totaled 5.1 million shares. Stock Repurchases for Tax Withholdings. In addition to the above-mentioned stock repurchases, during the third quarters of 2019 and 2018 we repurchased and then cancelled approximately 4,000 shares of common stock for $0.2 million and approximately 5,000 shares of common stock for $0.2 million, respectively, and during the nine months ended September 30, 2019 and 2018, we repurchased and then cancelled approximately 112,000 shares of common stock for $4.7 million and approximately 154,000 shares of common stock for $7.2 million, respectively, in connection with minimum tax withholding requirements resulting from the vesting of restricted common stock under our stock incentive plans. Cash During the third quarter of 2019, the Board approved a quarterly cash dividend of $0.2225 per share of common stock, totaling $7.3 million. During the third quarter of 2018, the Board approved a quarterly cash dividend of $0.21 per share of common stock, totaling $7.0 million. Dividends declared for the nine months ended September 30, 2019 and 2018 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 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 (“ACP”) based on various milestones. The Stock Warrants have a ten-year term and an exercise price of $26.68 per warrant. Upon vesting, the Stock Warrants were recorded as a client contract costs asset with the corresponding offset to stockholders’ equity. The client contract costs asset related to the Stock Warrants was amortized as a reduction in cloud and related solutions revenues over the original term of the Comcast amended agreement. As of June 30, 2019, the client contract costs asset related to these Stock Warrants was fully amortized. As of December 31, 2018, the client contract costs asset and accumulated amortization related to these Stock Warrants was $25.1 million and $19.8 million, respectively. As of September 30, 2019, 1.4 million Stock Warrants remain issued, of which 0.4 million were vested. Stock-Based Awards.

Accounting Policies [Abstract]
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 U.S. 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	Revenues. The majority of our future revenues 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. Our client contracts may also include guaranteed minimums and fixed monthly or annual fees. As of September 30, 2019, our aggregate amount of the transaction price allocated to the remaining performance obligations is approximately $454 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 85% of this amount by the end of 2021, 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. The nature, amount, timing and uncertainty of our revenues and how revenues and cash flows are affected by economic factors is most appropriately depicted by type of revenues and by geographic region (using the location of the client as the basis of attributing revenues to the individual regions) as follows (in thousands): Quarter Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Cloud and related solutions $ 224,347 $ 186,473 $ 666,120 $ 551,390 Software and services 14,406 14,283 39,607 39,573 Maintenance 12,661 12,299 36,336 36,829 Total revenues $ 251,414 $ 213,055 $ 742,063 $ 627,792 Quarter Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Americas (principally the U.S.) $ 218,694 $ 180,489 $ 643,814 $ 530,609 Europe, Middle East, and Africa 23,284 21,723 70,516 64,135 Asia Pacific 9,436 10,843 27,733 33,048 Total revenues $ 251,414 $ 213,055 $ 742,063 $ 627,792 Deferred revenue recognized during the quarter and nine months ended September 30, 2019 was $5.7 million and $35.5 million, respectively.
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 September 30, 2019 and December 31, 2018, our cash equivalents consist primarily of institutional money market funds, commercial paper, and time deposits held at major banks. As of September 30, 2019 and December 31, 2018, we had $2.8 million and $3.0 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 September 30, 2019 and December 31, 2018 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 September 30, 2019 and December 31, 2018 have contractual maturities of less than two years from the time of acquisition. Our short-term investments as of September 30, 2019 and December 31, 2018 consisted almost entirely of fixed income securities. Proceeds from the sale/maturity of short-term investments for the nine months ended September 30, 2019 and 2018 were $38.0 million and $190.5 million, respectively. Our short-term investments as of September 30, 2019 and December 31, 2018 were $11.3 million and $23.6 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 measured at fair value (in thousands): September 30, 2019 December 31, 2018 Level 1 Level 2 Total Level 1 Level 2 Total Cash equivalents: Money market funds $ 8,564 $ — $ 8,564 $ 4,392 $ — $ 4,392 Commercial paper — 2,794 2,794 — 9,078 9,078 Short-term investments: Corporate debt securities — 5,018 5,018 — 16,357 16,357 U.S. government agency bonds — 2,904 2,904 — 3,724 3,724 Asset-backed securities — 3,415 3,415 — 3,522 3,522 Total $ 8,564 $ 14,131 $ 22,695 $ 4,392 $ 32,681 $ 37,073 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): September 30, 2019 December 31, 2018 Carrying Fair Carrying Fair Value Value Value Value 2018 Credit Agreement (carrying value including current maturities) $ 138,750 $ 138,750 $ 144,375 $ 144,375 2016 Convertible debt (par value) 230,000 261,050 230,000 228,275 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.
Equity Method Investment	Equity Method Investment. During the nine months ended September 30, 2019, we made an additional $4 million investment in a payment technology and services company that enables omni-channel digital payments in Latin America. As of September 30, 2019, we held an 8% noncontrolling interest with a carrying value of $6.6 million.
Accounting Pronouncements	Accounting Pronouncements Adopted. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU requires lessees to recognize a right-of-use asset and lease liability for all leases, including operating leases, with a term greater than twelve months on its balance sheet. This ASU is effective for annual and interim periods beginning after December 31, 2018. An entity is required to use a modified retrospective transition approach, but may choose to use either the effective date or the beginning of the earliest comparative period presented in its financial statements as of the date of initial application. We adopted this ASU in January 2019, utilizing the effective date method of transition. Since we adopted this ASU utilizing the effective date method, prior period information in our Financial Statements has not been adjusted and continues to be as previously reported. We elected the package of practical expedients permitted under the transition guidance within the new standard. Additionally, we updated our polices to align with the new accounting guidance and our processes to ensure that we properly account for new, existing, and modifications to leases subsequent to the adoption of the ASU. In conjunction with the adoption of this ASU we recorded additional assets and liabilities of approximately $80 million related to the right-of-use assets and lease liabilities, and have included the amortization of the right-of-use-assets and the accretion and payments of lease liabilities in the changes in other current and non-current assets and liabilities and in the changes in trade accounts payable and accrued liabilities, respectively, on our Statement of Cash Flows.
