Accounting Policies [Abstract]
Condensed Consolidated Financial Statements	1. Condensed Consolidated Financial Statements The unaudited condensed consolidated financial statements include the accounts of ACI Worldwide, Inc. and its wholly-owned The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s annual report on Form 10-K The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States (“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 the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Receivables, net Receivables represent amounts billed and amounts earned that are to be billed in the near future. Included in accrued receivables are services, software as a service (“SaaS”) and platform as a service (“Platform”) revenues earned in the current period but billed in a subsequent period as well as license revenues that are fixed and determinable but billed in future periods. (in thousands) September 30, December 31, Billed Receivables $ 160,622 $ 250,116 Allowance for doubtful accounts (4,157 ) (3,873 ) Billed, net 156,465 246,243 Accrued Receivables 25,804 21,919 Receivables, net $ 182,269 $ 268,162 Other Current Assets and Other Current Liabilities (in thousands) September 30, December 31, Settlement deposits $ 6,392 $ 10,496 Settlement receivables 7,239 14,327 Other 11,337 8,755 Total other current assets $ 24,968 $ 33,578 (in thousands) September 30, December 31, Settlement payables $ 13,107 $ 24,016 Accrued interest 2,469 7,356 Vendor financed licenses 2,092 9,213 Royalties payable 7,073 7,197 Other 28,275 31,059 Total other current liabilities $ 53,016 $ 78,841 Individuals and businesses settle their obligations to the Company’s various clients, primarily utility and other public sector clients, using credit or debit cards or via ACH payments. The Company creates a receivable for the amount due from the credit or debit card company and an offsetting payable to the client. Once confirmation is received that the funds have been received, the Company settles the obligation to the client. Due to timing, in some instances, the Company may receive the funds into bank accounts controlled by and in the Company’s name that are not disbursed to its clients by the end of the day resulting in a settlement deposit on the Company’s books. Off Balance Sheet Accounts The Company also enters into agreements with certain clients to process payment funds on their behalf. When an automated clearing house or automated teller machine network payment transaction is processed, a transaction is initiated to withdraw funds from the designated source account and deposit them into a settlement account, which is a trust account maintained for the benefit of the Company’s clients. A simultaneous transaction is initiated to transfer funds from the settlement account to the intended destination account. These “back to back” transactions are designed to settle at the same time, usually overnight, such that the Company receives the funds from the source at the same time as it sends the funds to their destination. However, due to the transactions being with various financial institutions there may be timing differences that result in float balances. These funds are maintained in accounts for the benefit of the client which is separate from the Company’s corporate assets. As the Company does not take ownership of the funds, the settlement accounts are not included in the Company’s balance sheet. The Company is entitled to interest earned on the fund balances. The collection of interest on these settlement accounts is considered in the Company’s determination of its fee structure for clients and represents a portion of the payment for services performed by the Company. The amount of settlement funds as of September 30, 2017 and December 31, 2016 were $223.9 million and $270.0 million, respectively. Fair Value The fair value of the Company’s Credit Agreement approximates the carrying value due to the floating interest rate (Level 2 of the fair value hierarchy). The Company measures the fair value of its Senior Notes based on Level 2 inputs, which include quoted market prices and interest rate spreads of similar securities. The fair value of the Company’s Senior Notes was $305.4 million and $309.8 million at September 30, 2017 and December 31, 2016, respectively. The fair values of cash and cash equivalents approximate the carrying values due to the short period of time to maturity (Level 2 of the fair value hierarchy). Goodwill Changes in the carrying amount of goodwill attributable to each reporting unit with goodwill balances during the nine months ended September 30, 2017 were as follows: (in thousands) ACI On Demand ACI On Premise Total Gross Balance prior to December 31, 2016 $ 183,783 $ 773,340 $ 957,123 Total impairment prior to December 31, 2016 — (47,432 ) (47,432 ) Balance, December 31, 2016 183,783 725,908 909,691 Adjustments — — — Balance, September 30, 2017 $ 183,783 $ 725,908 $ 909,691 In accordance with the Accounting Standards Codification (“ASC 350”), Intangibles – Goodwill and Other, The Company evaluates goodwill at the reporting unit level, and as discussed in Note 10, Segment Information Recently Issued Accounting Standards Not Yet Effective In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers Revenue Recognition During 2016, the Company began its detailed assessment of the impact of ASC 606 and completed its initial assessment of the impact on its license, maintenance, and services revenues. This assessment continued during early 2017, with increased focus on the impact of ASC 606 on SaaS and Platform revenues, detailed review of customer contracts under ASC 606 for each revenue stream, identification of key data requirements for contract reviews and necessary changes to processes, systems, and internal controls. As of September 30, 2017 the Company has completed its initial assessment of the impact of ASC 606 on all revenue streams. The Company has considered and evaluated the data necessary to comply with the expanded disclosures required under the new standard and has started to make changes to its processes and systems. The Company continues to evaluate the impact of the standard on its consolidated financial statements and related disclosures and is actively engaged in the process of preparing its transition adjustment under the modified retrospective transition method. The Company continues to believe that the most significant impacts relate to changes in the timing and amount of recognition for software license revenues and sales commission expenses and the expanded qualitative and quantitative disclosures required under the new standard. The Company expects revenue related to maintenance, services, and SaaS and Platform to remain substantially unchanged. While the Company continues to make progress in preparing for the adoption of ASC 606, work remains due to the complexity of applying ASC 606 to our contracts, the increased number of judgments and estimates required, and the volume of contracts that are subject to review. Accordingly, our assessment of ASC 606 will continue through the effective date. As it relates to software license revenues, under ASC 606 the Company will recognize revenue in advance of billings for certain software license arrangements with extended payment terms as opposed to when payments become due and payable. Additionally, certain of those same software license arrangements will contain a significant financing component which will result in a change in the amount of the contract value that is allocated to software license revenue. Because the requirement to have vendor-specific objective evidence (“VSOE”) of fair value for undelivered elements is eliminated under the new standard, the Company expects the amounts allocated to software license, maintenance, and services revenues for most software license arrangements to be recognized as each element is delivered or provided to the customer. Under current U.S. GAAP, when software license arrangements include post contract customer support (maintenance or “PCS”) terms that fail to achieve VSOE of fair value, the Company recognizes all revenues in the arrangement ratably over the longer service period. The Company has performed a detailed review of its active software license arrangements (as of August 31, 2017) including contracts with software license payment terms that extend beyond one year from the delivery of the software license and continue beyond December 31, 2017. The Company assessed whether those arrangements contain a significant financing component and, if so, calculated the amount of significant financing component at contract execution and the estimated remaining balance on January 1, 2018. Upon adoption of ASC 606, the Company will record an accrued receivable in its condensed consolidated balance sheet which represents the Company’s unconditional right to consideration at its present value (i.e. adjusted for the significant financing component) with an offsetting increase to retained earnings. The significant financing component will be recognized as interest income in the Company’s condensed consolidated statement of operations over the remaining contract term. The amounts allocated to the significant financing component would have been recognized as revenue under current U.S. GAAP. The Company has determined that its SaaS-based and Platform-based arrangements represent a single promise to provide continuous access (i.e. a stand-ready obligation) to its software solutions and their processing capabilities in the form of a service through one of the Company’s data centers. As each day of providing access to the software solution(s) is substantially the same and the customer simultaneously receives and consumes the benefits as access is provided, the Company has determined that its SaaS-based and Platform-based arrangements include a single performance obligation comprised of a series of distinct services. The Company’s SaaS-based and Platform-based arrangements may include fixed consideration, variable consideration or a combination of the two. Variable consideration in these arrangements is typically a function of a tier-based pricing structure that provides that customer with levels of transaction volume that “reset” with varying frequencies (e.g. monthly, quarterly or annually) and the corresponding rate per transaction within each level. Depending upon the structure of a particular arrangement, the Company will either: (1) allocate the variable amount to each distinct service period within the series and recognize revenue as each distinct service period is performed (i.e. direct allocation), (2) estimate total variable consideration at contract inception (giving consideration to any constraints that may apply) and recognize the total transaction price over the period to which it relates, or (3) apply ‘right to invoice’ practical expedient. At this time, the Company believes that revenue from most of its SaaS-based and Platform-based arrangements will be recognized under the direct allocation method or by applying the ‘right to invoice’ practical expedient, which will result in the same pattern of recognition as under current U.S. GAAP. The Company has determined that most of its sales commissions meet the definition of incremental costs of obtaining a contract. Accordingly, the costs associated with those sales commissions will be capitalized and expense recognized as the related goods or services are transferred to the customer. The Company currently recognizes sales commission expenses as they are incurred. Upon adoption of ASC 606, the Company will record an asset in its condensed consolidated balance sheet (as part of the transition adjustment) for the amount of unamortized sales commissions that were incurred in obtaining contracts in prior periods with an offsetting increase to retained earnings. The Company will recognize the capitalized sales commissions as a selling and marketing expense in the Company’s condensed consolidated statement of operations over a period that is consistent with the transfer of the goods and services to which the asset relates.

Divestiture	2. Divestiture Community Financial Services On March 3, 2016, the Company completed the sale of its Community Financial Services (“CFS”) related assets and liabilities, to Fiserv, Inc. (“Fiserv”) for $200.0 million. The sale of CFS, which was not aligned with the Company’s long-term strategy, is part of the Company’s ongoing efforts to expand as a provider of software products, SaaS and Platform solutions facilitating real-time electronic and eCommerce payments for large financial institutions, intermediaries, retailers, and billers worldwide. The sale included employee agreements and customer contracts as well as technology assets and intellectual property. For the nine months ended September 30, 2016, the Company recognized a net after-tax The Company and Fiserv also entered into a Transition Services Agreement (“TSA”), whereby the Company continues to perform certain functions on Fiserv’s behalf during the migration period. The TSA is meant to reimburse the Company for direct costs incurred in order to provide such functions which are no longer generating revenue for the Company.

Debt Disclosure [Abstract]
Debt	3. Debt As of September 30, 2017, the Company had $4.0 million, $399.4 million, and $300.0 million outstanding under its Revolving Credit Facility, Term Credit Facility and Senior Notes, respectively, with up to $496.0 million of unused and available borrowings under the Revolving Credit Facility portion of the Credit Agreement, as amended. Credit Agreement On February 24, 2017, the Company entered into an amended and restated credit agreement (the “Credit Agreement”), replacing the existing agreement, with a syndicate of financial institutions, as lenders, and Bank of America, N.A. (“BofA”), as Administrative Agent, providing for revolving loans, swingline loans, letters of credit, and a term loan. The Credit Agreement consists of a five-year $500.0 million senior secured revolving credit facility (the “Revolving Credit Facility”), which includes a sublimit for the issuance of standby letters of credit and a sublimit for swingline loans, and $415.0 million under the five-year senior secured term loan facility (the “Term Credit Facility” and, together with the Revolving Credit Facility, the “Credit Facility”). The Credit Agreement also allows the Company to request optional incremental term loans and increases in the revolving commitment. The loans under the Credit Facility may be made to, and the letters of credit under the Revolving Credit Facility may be issued on behalf of the Company. On February 24, 2017, the Company borrowed an aggregate principal amount of $12.0 million under the Revolving Credit Facility and borrowed $415.0 million under the Term Credit Facility. Borrowings under the Credit Facility bear interest at a rate per annum equal to, at the Company’s option, either (a) a base rate determined by reference to the highest of (1) the rate of interest per annum publicly announced by the Administrative Agent as its Prime Rate, (2) the federal funds effective rate plus 1/2 of 1% and (3) a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for a one-month In addition to paying interest on the outstanding principal under the Credit Facility, the Company is required to pay a commitment fee in respect of the unutilized commitments under the Revolving Credit Facility, payable quarterly in arrears. The Company is also required to pay letter of credit fees on the maximum amount available to be drawn under all outstanding letters of credit in an amount equal to the applicable margin on LIBOR rate borrowings under the Revolving Credit Facility on a per annum basis, payable quarterly in arrears, as well as customary fronting fees for the issuance of letters of credit fees and agency fees. The Company’s obligations under the Credit Facility and certain hedging arrangements and cash management arrangements entered into with lenders under the Credit Facility (or affiliates thereof) and the obligations of the subsidiary guarantors are secured by first-priority security interests in substantially all assets of the Company and any guarantor, including 100% of the capital stock of ACI Worldwide Corp. and each domestic subsidiary of the Company, each domestic subsidiary of any guarantor, and 65% of the voting capital stock of each foreign subsidiary of the Company that is directly owned by the Company or a guarantor, in each case subject to certain exclusions set forth in the credit documentation governing the Credit Facility. The Credit Agreement contains a number of covenants that, among other things and subject to certain exceptions, restrict the Company’s ability and, as applicable, the ability of its subsidiaries to: create, incur, assume or suffer to exist any additional indebtedness; create, incur, assume or suffer to exist any liens; enter into agreements and other arrangements that include negative pledge clauses; pay dividends on capital stock or redeem, repurchase or retire capital stock or subordinated indebtedness; create restrictions on the payment of dividends or other distributions by subsidiaries; make investments, loans, advances and acquisitions; merge, consolidate or enter into any similar combination or sell assets, including equity interests of the subsidiaries; enter into sale and leaseback transactions; directly or indirectly engage in transactions with affiliates; alter in any material respect the character or conduct of the business; enter into amendments of or waivers under subordinated indebtedness, organizational documents and certain other material agreements; and hold certain assets and incur certain liabilities. The Credit Agreement also contains certain customary affirmative covenants and events of default. If an event of default, as specified in the Credit Agreement, shall occur and be continuing, the Company may be required to repay all amounts outstanding under the Credit Facility. Letter of Credit On February 29, 2016, the Company entered into a standby letter of credit (the “Letter of Credit”), under the terms of the Credit Agreement, for $25.0 million. On October 26, 2016, the Letter of Credit was renewed at $7.5 million. On June 15, 2017, the Letter of Credit was renewed at $5.0 million.

Stock-Based Compensation Plans	4. Stock-Based Employee Stock Purchase Plan On April 6, 2017, the Board of Directors approved the 2017 Employee Stock Purchase Plan (“2017 ESPP”), which was approved by shareholders at the 2017 Annual Shareholder meeting. The 2017 ESPP provides employees with an opportunity to purchase shares of Common Stock in the Company. The 1999 Employee Stock Purchase Plan terminated upon the August 1, 2017 effective date of the 2017 ESPP. Under the Company’s 2017 ESPP a total of 3,000,000 shares of the Company’s common stock have been reserved for issuance to eligible employees. Participating employees are permitted to designate up to the lesser of $25,000 or 10% of their annual base compensation for the purchase of common stock under the ESPP. Purchases under the ESPP are made one calendar month after the end of each fiscal quarter. The price for shares of common stock purchased under the ESPP is 85% of the stock’s fair market value on the last business day of the three-month participation period. Shares issued under the ESPP during the nine months ended September 30, 2017 and 2016 totaled 121,765 and 141,484, respectively. Stock-Based Payments A summary of stock options issued pursuant to the Company’s stock incentive plans is as follows: Number of Weighted- Weighted- Aggregate In-the-Money Outstanding as of December 31, 2016 6,791,375 $ 15.54 Granted 864,800 20.12 Exercised (756,140 ) 13.60 Forfeited (207,559 ) 18.46 Expired (17,507 ) 20.36 Outstanding as of September 30, 2017 6,674,969 $ 16.25 6.60 $ 43,563,796 Exercisable as of September 30, 2017 3,938,286 $ 14.45 5.31 $ 32,792,014 The weighted-average grant date fair value of stock options granted during the nine months ended September 30, 2017 and 2016 was $6.24 and $5.59, respectively. The Company issued treasury shares for the exercise of stock options during the nine months ended September 30, 2017 and 2016. The total intrinsic value of stock options exercised during the nine months ended September 30, 2017 and 2016 was $6.6 million and $6.7 million, respectively. For options that do not vest based on the achievement of certain market conditions the grant date fair values were estimated on the date of grant using the Black-Scholes option-pricing , Nine Months Ended Nine Months Ended Expected life (years) 5.6 5.9 Interest rate 1.9 % 1.2 % Volatility 29.4 % 29.7 % Dividend yield — — Expected volatilities are based on the Company’s historical common stock volatility derived from historical stock price data for historical periods commensurate with the options’ expected life. The expected life is the average number of years that the Company estimated that the options will be outstanding, based primarily on historical employee option exercise behavior. The risk-free interest rate is based on the implied yield currently available on United States Treasury zero coupon issues with a term equal to the expected term at the date of grant of the options. The expected dividend yield is zero as the Company has historically paid no dividends and does not anticipate dividends to be paid in the future. During the nine months ended September 30, 2016, the Company granted stock options with three tranches at a grant date fair value of $7.46, $7.06, and $6.50, respectively, per share. These options vest, if at all, based upon (i) tranche one - any time after the third anniversary date if the stock has traded at 133% of the exercise price for at least 20 consecutive trading days, (ii) tranche two - any time after the fourth anniversary date if the stock has traded at 167% of the exercise price for at least 20 consecutive trading days, and (iii) tranche three - any time after the fifth anniversary date if the stock has traded at 200% of the exercise price for at least 20 consecutive trading days. The employees must also remain employed with the Company as of the anniversary date in order for the options to vest. The exercise price of the stock options is the closing market price on the date the awards were granted. In order to determine the grant date fair value of the stock options, a Monte Carlo simulation model was used. With respect to options granted that vest based on the achievement of certain market conditions, the grant date fair value of such options was estimated using the following weighted-average assumptions: Nine Months Ended Expected life (years) 7.5 Interest rate 1.6 % Volatility 41.6 % Dividend yield — A summary of nonvested long-term incentive program performance share awards (“LTIP Performance Shares”) outstanding as of September 30, 2017 and changes during the period are as follows: Nonvested LTIP Performance Shares Number of Weighted- Nonvested as of December 31, 2016 1,738,056 $ 18.45 Granted 553,549 20.12 Forfeited (150,241 ) 18.77 Nonvested as of September 30, 2017 2,141,364 $ 18.86 A summary of nonvested restricted share awards (“RSAs”) as of September 30, 2017 and changes during the period are as follows: Nonvested Restricted Share Awards Number of Weighted-Average Grant Nonvested as of December 31, 2016 172,108 $ 20.62 Granted 560,174 20.61 Vested (120,869 ) 20.72 Forfeited (79,665 ) 20.47 Nonvested as of September 30, 2017 531,748 $ 20.60 During the nine months ended September 30, 2017, a total of 120,869 shares of the RSAs vested.

Segment Reporting [Abstract]
Segment Information	10. Segment Information In January 2017, the Company announced a change in organizational structure to align with its strategic direction. As a result, beginning January 1, 2017, the Company reports financial performance based on its new segments, ACI On Premise and ACI On Demand, and analyzes operating income as a measure of segment profitability. The Company’s chief operating decision maker (“CODM”), which is also our Chief Executive Officer, together with other senior management personnel, focus their review of consolidated financial information and the allocation of resources based upon the operating results, including revenues and operating income, for the segments ACI On Premise and ACI On Demand, separate from the Corporate operations. ACI On Premise on-premise ACI On Demand Revenue is attributed to the reportable segments based upon the product sold and mechanism for delivery to the customer. Expenses are attributed to the reportable segments in one of three methods, (1) direct costs of the segment, (2) labor costs that can be attributed based upon time tracking for individual products, or (3) costs that are allocated. Allocated costs are generally marketing and sales related activities as well as information technology and facilities related expense for which multiple segments benefit. The Company also allocates certain depreciation costs to the segments. Corporate and other consists of the corporate overhead costs that are not allocated to reportable segments. These overhead costs relate to human resources, finance, legal, accounting, merger and acquisition activity, amortization of acquisition-related intangibles, and other costs that are not considered when management evaluates segment performance. For the nine months ended September 30, 2017, Corporate and other includes $46.7 million of general and administrative expense for the legal judgment discussed in Note 12.

Income Tax Disclosure [Abstract]
Income Taxes	11. Income Taxes The Company reported a tax benefit for the three months ended September 30, 2017 while reporting a pretax profit for the same period. The resulting effective tax rate is a negative 193%. The effective tax rate for the nine months ended September 30, 2017 was 49%. The earnings of the Company’s foreign entities for the three and nine months ended September 30, 2017 were $15.2 million and $40.6 million. The tax rates in the foreign jurisdictions in which the Company operates are less than the domestic tax rate. The effective tax rates for the three and nine months ended September 30, 2017 were impacted by profits and losses in certain foreign jurisdictions taxed at lower rates and domestic losses taxed at higher rates. The effective tax rates for the three and nine months ended September 30, 2016 were 40% and 17%, respectively. The earnings of the Company’s foreign entities for the three and nine months ended September 30, 2016 were $16.4 million and $44.0 million, respectively. The tax rates in the foreign jurisdictions in which the Company operates are less than the domestic tax rate. The effective tax rate for the three and nine months ended September 30, 2016 was reduced by foreign profits taxed at lower rates. The effective tax rate for the three months ended September 30, 2016 was increased by the establishment of a $4.7 million valuation allowance against foreign tax credits existing in the US that were expected to expire before they can be utilized. The effective tax rate for the nine months ended September 30, 2016 was also reduced by a net release of $5.4 million valuation allowance previously established against foreign tax credits that were expected to be fully utilized as a result of the sale of the CFS assets and liabilities. The Company’s effective tax rate could fluctuate significantly on a quarterly basis and could be negatively affected to the extent earnings are lower in the countries in which it operates that have a lower statutory rate or higher in the countries in which it operates that have a higher statutory rate or to the extent it has losses sustained in countries where the future utilization of losses are uncertain. The Company’s effective tax rate could also fluctuate due to changes in the valuation of its deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, the Company is occasionally subject to examination of its income tax returns by tax authorities in the jurisdictions it operates. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of its provision for income taxes. The amount of unrecognized tax benefits for uncertain tax positions was $25.6 million as of September 30, 2017 and $24.3 million as of December 31, 2016, excluding related liabilities for interest and penalties of $1.5 million and $1.9 million as of September 30, 2017 and December 31, 2016, respectively. The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $1.4 million, due to the settlement of various audits and the expiration of statutes of limitation.

Commitments and Contingencies	12. Commitments and Contingencies Legal Proceedings On September 23, 2015, a jury verdict was returned against ACI Worldwide Corp. (“ACI Corp.”), a subsidiary of the Company, for $43.8 million in connection with counterclaims brought by Baldwin Hackett & Meeks, Inc. (“BHMI”) in the District Court of Douglas County, Nebraska. On September 21, 2012, ACI Corp. had sued BHMI for misappropriation of ACI Corp.’s trade secrets. The jury found that ACI Corp. had not met its burden of proof regarding these claims. On March 6, 2013, BHMI asserted counterclaims for breach of a non-disclosure Indemnities Under certain customer contracts, the Company indemnifies customers for certain matters including third party claims of intellectual property infringement relating to the use of our products.

The Company creates a receivable for the amount due from the credit or debit card company and an offsetting payable to the client. Once confirmation is received that the funds have been received, the Company settles the obligation to the client. Due to timing, in some instances, the Company may receive the funds into bank accounts controlled by and in the Company’s name that are not disbursed to its clients by the end of the day resulting in a settlement deposit on the Company’s books.
Off Balance Sheet Accounts	Off Balance Sheet Accounts The Company also enters into agreements with certain clients to process payment funds on their behalf. When an automated clearing house or automated teller machine network payment transaction is processed, a transaction is initiated to withdraw funds from the designated source account and deposit them into a settlement account, which is a trust account maintained for the benefit of the Company’s clients. A simultaneous transaction is initiated to transfer funds from the settlement account to the intended destination account. These “back to back” transactions are designed to settle at the same time, usually overnight, such that the Company receives the funds from the source at the same time as it sends the funds to their destination. However, due to the transactions being with various financial institutions there may be timing differences that result in float balances. These funds are maintained in accounts for the benefit of the client which is separate from the Company’s corporate assets. As the Company does not take ownership of the funds, the settlement accounts are not included in the Company’s balance sheet. The Company is entitled to interest earned on the fund balances. The collection of interest on these settlement accounts is considered in the Company’s determination of its fee structure for clients and represents a portion of the payment for services performed by the Company. The amount of settlement funds as of September 30, 2017 and December 31, 2016 were $223.9 million and $270.0 million, respectively.
Fair Value	Fair Value The fair value of the Company’s Credit Agreement approximates the carrying value due to the floating interest rate (Level 2 of the fair value hierarchy). The Company measures the fair value of its Senior Notes based on Level 2 inputs, which include quoted market prices and interest rate spreads of similar securities. The fair value of the Company’s Senior Notes was $305.4 million and $309.8 million at September 30, 2017 and December 31, 2016, respectively. The fair values of cash and cash equivalents approximate the carrying values due to the short period of time to maturity (Level 2 of the fair value hierarchy).

Recently Issued Accounting Standards Not Yet Effective	Recently Issued Accounting Standards Not Yet Effective In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers Revenue Recognition During 2016, the Company began its detailed assessment of the impact of ASC 606 and completed its initial assessment of the impact on its license, maintenance, and services revenues. This assessment continued during early 2017, with increased focus on the impact of ASC 606 on SaaS and Platform revenues, detailed review of customer contracts under ASC 606 for each revenue stream, identification of key data requirements for contract reviews and necessary changes to processes, systems, and internal controls. As of September 30, 2017 the Company has completed its initial assessment of the impact of ASC 606 on all revenue streams. The Company has considered and evaluated the data necessary to comply with the expanded disclosures required under the new standard and has started to make changes to its processes and systems. The Company continues to evaluate the impact of the standard on its consolidated financial statements and related disclosures and is actively engaged in the process of preparing its transition adjustment under the modified retrospective transition method. The Company continues to believe that the most significant impacts relate to changes in the timing and amount of recognition for software license revenues and sales commission expenses and the expanded qualitative and quantitative disclosures required under the new standard. The Company expects revenue related to maintenance, services, and SaaS and Platform to remain substantially unchanged. While the Company continues to make progress in preparing for the adoption of ASC 606, work remains due to the complexity of applying ASC 606 to our contracts, the increased number of judgments and estimates required, and the volume of contracts that are subject to review. Accordingly, our assessment of ASC 606 will continue through the effective date. As it relates to software license revenues, under ASC 606 the Company will recognize revenue in advance of billings for certain software license arrangements with extended payment terms as opposed to when payments become due and payable. Additionally, certain of those same software license arrangements will contain a significant financing component which will result in a change in the amount of the contract value that is allocated to software license revenue. Because the requirement to have vendor-specific objective evidence (“VSOE”) of fair value for undelivered elements is eliminated under the new standard, the Company expects the amounts allocated to software license, maintenance, and services revenues for most software license arrangements to be recognized as each element is delivered or provided to the customer. Under current U.S. GAAP, when software license arrangements include post contract customer support (maintenance or “PCS”) terms that fail to achieve VSOE of fair value, the Company recognizes all revenues in the arrangement ratably over the longer service period. The Company has performed a detailed review of its active software license arrangements (as of August 31, 2017) including contracts with software license payment terms that extend beyond one year from the delivery of the software license and continue beyond December 31, 2017. The Company assessed whether those arrangements contain a significant financing component and, if so, calculated the amount of significant financing component at contract execution and the estimated remaining balance on January 1, 2018. Upon adoption of ASC 606, the Company will record an accrued receivable in its condensed consolidated balance sheet which represents the Company’s unconditional right to consideration at its present value (i.e. adjusted for the significant financing component) with an offsetting increase to retained earnings. The significant financing component will be recognized as interest income in the Company’s condensed consolidated statement of operations over the remaining contract term. The amounts allocated to the significant financing component would have been recognized as revenue under current U.S. GAAP. The Company has determined that its SaaS-based and Platform-based arrangements represent a single promise to provide continuous access (i.e. a stand-ready obligation) to its software solutions and their processing capabilities in the form of a service through one of the Company’s data centers. As each day of providing access to the software solution(s) is substantially the same and the customer simultaneously receives and consumes the benefits as access is provided, the Company has determined that its SaaS-based and Platform-based arrangements include a single performance obligation comprised of a series of distinct services. The Company’s SaaS-based and Platform-based arrangements may include fixed consideration, variable consideration or a combination of the two. Variable consideration in these arrangements is typically a function of a tier-based pricing structure that provides that customer with levels of transaction volume that “reset” with varying frequencies (e.g. monthly, quarterly or annually) and the corresponding rate per transaction within each level. Depending upon the structure of a particular arrangement, the Company will either: (1) allocate the variable amount to each distinct service period within the series and recognize revenue as each distinct service period is performed (i.e. direct allocation), (2) estimate total variable consideration at contract inception (giving consideration to any constraints that may apply) and recognize the total transaction price over the period to which it relates, or (3) apply ‘right to invoice’ practical expedient. At this time, the Company believes that revenue from most of its SaaS-based and Platform-based arrangements will be recognized under the direct allocation method or by applying the ‘right to invoice’ practical expedient, which will result in the same pattern of recognition as under current U.S. GAAP. The Company has determined that most of its sales commissions meet the definition of incremental costs of obtaining a contract. Accordingly, the costs associated with those sales commissions will be capitalized and expense recognized as the related goods or services are transferred to the customer. The Company currently recognizes sales commission expenses as they are incurred. Upon adoption of ASC 606, the Company will record an asset in its condensed consolidated balance sheet (as part of the transition adjustment) for the amount of unamortized sales commissions that were incurred in obtaining contracts in prior periods with an offsetting increase to retained earnings. The Company will recognize the capitalized sales commissions as a selling and marketing expense in the Company’s condensed consolidated statement of operations over a period that is consistent with the transfer of the goods and services to which the asset relates.

Earnings (Loss) per share	Basic earnings (loss) per share is computed on the basis of weighted average outstanding common shares. Diluted earnings (loss) per share is computed on the basis of basic weighted average outstanding common shares adjusted for the dilutive effect of stock options and other outstanding dilutive securities.
Segment Information	In January 2017, the Company announced a change in organizational structure to align with its strategic direction. As a result, beginning January 1, 2017, the Company reports financial performance based on its new segments, ACI On Premise and ACI On Demand, and analyzes operating income as a measure of segment profitability. The Company’s chief operating decision maker (“CODM”), which is also our Chief Executive Officer, together with other senior management personnel, focus their review of consolidated financial information and the allocation of resources based upon the operating results, including revenues and operating income, for the segments ACI On Premise and ACI On Demand, separate from the Corporate operations. ACI On Premise on-premise ACI On Demand Revenue is attributed to the reportable segments based upon the product sold and mechanism for delivery to the customer. Expenses are attributed to the reportable segments in one of three methods, (1) direct costs of the segment, (2) labor costs that can be attributed based upon time tracking for individual products, or (3) costs that are allocated. Allocated costs are generally marketing and sales related activities as well as information technology and facilities related expense for which multiple segments benefit. The Company also allocates certain depreciation costs to the segments. Corporate and other consists of the corporate overhead costs that are not allocated to reportable segments. These overhead costs relate to human resources, finance, legal, accounting, merger and acquisition activity, amortization of acquisition-related intangibles, and other costs that are not considered when management evaluates segment performance. For the nine months ended September 30, 2017, Corporate and other includes $46.7 million of general and administrative expense for the legal judgment discussed in Note 12. For the nine months ended September 30, 2016, Corporate and other also includes revenue and operating income from the operations and sale of CFS related assets and liabilities of $15.4 million and $151.7 million, respectively.
