NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)
1. Condensed Consolidated Financial Statements
The unaudited condensed consolidated financial statements include the accounts of ACI Worldwide, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements as of September 30, 2023, and for the three and nine months ended September 30, 2023 and 2022, are unaudited and reflect all adjustments of a normal recurring nature, which are, in the opinion of management, necessary for a fair presentation, in all material respects, of the financial position and operating results for the interim periods. The condensed consolidated balance sheet as of December 31, 2022, is derived from the audited financial statements.
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 for the fiscal year ended December 31, 2022, filed on March 1, 2023. Results for the three and nine months ended September 30, 2023, are not necessarily indicative of results that may be attained in the future.
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 judgments, 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. These estimates and assumptions are affected by management’s application of accounting policies, as well as uncertainty in the current economic environment. Actual results could differ from those estimates.
Other Current Liabilities
The components of other current liabilities are included in the following table (in thousands):

| September 30, 2023 |  | December 31, 2022
Operating lease liabilities | $ | 9,659 |  |  | $ | 11,218 |
Vendor financed licenses | 8,378 |  |  | 13,525 |
Accrued interest | 3,498 |  |  | 9,067 |
Royalties payable | 2,536 |  |  | 3,726 |
Other | 53,839 |  |  | 65,109 |
Total other current liabilities | $ | 77,910 |  |  | $ | 102,645 |

Settlement Assets and Liabilities
Individuals and businesses settle their obligations to the Company’s various Biller clients using credit or debit cards or via automated clearing house (“ACH”) payments. The Company creates a receivable for the amount due from the credit or debit card processor and an offsetting payable to the client. Upon confirmation that the funds have been received, the Company settles the obligation to the client. Due to timing, in some instances, the Company may (1) 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 and (2) disburse funds to its clients in advance of receiving funds from the credit or debit card processor, resulting in a net settlement receivable position.
Off Balance Sheet Settlement Accounts
The Company also enters into agreements with certain Biller clients to process payment funds on their behalf. When an ACH 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, these 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, 2023, and December 31, 2022, was $278.4 million and $328.7 million, respectively.

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 5.750% Senior Notes due 2026 (“2026 Notes”) was $388.0 million and $390.0 million as of September 30, 2023, and December 31, 2022, 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
In accordance with the Accounting Standards Codification ("ASC") 350, Intangibles – Goodwill and Other, the Company assesses goodwill for impairment annually during the fourth quarter of its fiscal year using October 1 balances or when there is evidence that events or changes in circumstances indicate that the carrying amount of the asset may not be recovered. The Company evaluates goodwill at the reporting unit level and has identified its operating segments, Banks, Merchants, and Billers, as the reporting units. As of September 30, 2023, the Company's goodwill balance of $1.2 billion was allocated $671.7 million to Banks, $137.3 million to Merchants, and $417.0 million to Billers.
Recoverability of goodwill is measured using a discounted cash flow model incorporating discount rates commensurate with the risks involved. Use of a discounted cash flow model is common practice in impairment testing in the absence of available transactional market evidence to determine the fair value. The calculated fair value was substantially in excess of the current carrying value for all reporting units based upon the October 1, 2022, annual impairment test and there have been no indications of impairment in the subsequent periods.
Equity Method Investment
In July 2019, the Company invested $18.3 million for a 30% non-controlling financial interest in a payment technology and services company in India. The Company accounted for this investment using the equity method in accordance with ASC 323, Investments - Equity Method and Joint Ventures. The Company records its share of earnings and losses in the investment on a one-quarter lag basis. Accordingly, the Company recorded an investment of $18.3 million and $17.9 million, which is included in other noncurrent assets in the condensed consolidated balance sheet as of September 30, 2023, and December 31, 2022, respectively.
2. Revenue
In accordance with ASC 606, Revenue From Contracts With Customers, revenue is recognized upon transfer of control of promised products and/or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products and services. Revenue is recognized net of any taxes collected from customers and subsequently remitted to governmental authorities. See Note 10, Segment Information, for additional information, including disaggregation of revenue based on primary solution category.
Total receivables represent amounts billed and amounts earned that are to be billed in the future (i.e., accrued receivables). Included in accrued receivables are services, software as a service ("SaaS"), and platform as a service ("PaaS") revenues earned in the current period but billed in the following period, and amounts due under multi-year software license arrangements with extended payment terms for which the Company has an unconditional right to invoice and receive payment subsequent to invoicing.

On May 5, 2022, the Company and Bank of America entered into the LIBOR Transition Amendment (the "Amendment") that replaced the LIBOR reference rate with the Secured Overnight Financing Rate ("SOFR") reference rate. No other terms or conditions of the Credit Agreement were changed as a result of the Amendment.
On April 28, 2023, the Company and Bank of America entered into the 2023 Extension Amendment to extend the term of the Credit Facility one year to April 5, 2025. All other terms remained the same.
The Credit Agreement consists of (a) a five-year $500.0 million senior secured revolving credit facility (the “Revolving Credit Facility”), which includes sublimits for (1) the issuance of standby letters of credit and (2) swingline loans, (b) a five-year $279.0 million senior secured term loan facility (the "Initial Term Loan") and (c) a five-year $500.0 million Delayed Draw Term Loan (together with the Initial Term Loan, the "Term Loans", and together with the Initial Term Loan and the Revolving Credit Facility, the “Credit Facility”).

Based on the calculation of the applicable consolidated total leverage ratio, the applicable margin for borrowings under the Credit Facility is between 0.25% to 1.25% with respect to base rate borrowings and between 1.25% and 2.25% with respect to SOFR rate borrowings. Interest is due and payable monthly. The interest rate in effect for the Credit Facility as of September 30, 2023, was 7.42%.
The Company is also required to pay (a) a commitment fee related to the unutilized commitments under the Revolving Credit Facility, payable quarterly in arrears, (b) 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 SOFR rate borrowings under the Revolving Credit Facility on an annual basis, payable quarterly in arrears, and (c) customary fronting fees for the issuance of letters of credit fees and agency fees.

8. Earnings (Loss) Per Share
Basic earnings (loss) per share is computed in accordance with ASC 260, Earnings Per Share, based on weighted average outstanding common shares. Diluted earnings (loss) per share is computed based on basic weighted average outstanding common shares adjusted for the dilutive effect of stock options, RSUs, and certain contingently issuable shares for which performance targets have been achieved.
The following table reconciles the weighted average share amounts used to compute both basic and diluted earnings per share (in thousands):

| Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2023 |  | 2022 |  | 2023 |  | 2022
Weighted average shares outstanding: |  |  |  |  |  |  |
Basic weighted average shares outstanding | 108,667 |  |  | 113,812 |  |  | 108,428 |  |  | 114,584 |
Add: Dilutive effect of stock options and RSUs | 266 |  |  | 536 |  |  | — |  |  | 627 |
Diluted weighted average shares outstanding | 108,933 |  |  | 114,348 |  |  | 108,428 |  |  | 115,211 |

The diluted earnings (loss) per share computation excludes 2.0 million options to purchase shares, RSUs, and contingently issuable shares during both the three months ended September 30, 2023 and 2022, as their effect would be anti-dilutive. The diluted earnings (loss) per share computation excludes 3.2 million and 2.0 million options to purchase shares, RSUs, and contingently issuable shares during the nine months ended September 30, 2023 and 2022, respectively, as their effect would be anti-dilutive.
Common stock outstanding as of September 30, 2023, and December 31, 2022, was 108,722,535 and 108,068,828, respectively.
9. Other, Net

Table of contents
Revenue is attributed to the reportable segments based upon 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 projects, or (3) costs that are allocated. Allocated costs are generally marketing and sales related activities.
Segment Adjusted EBITDA is the measure reported to the CODM for purposes of making decisions on allocating resources and assessing the performance of the Company’s segments, and, therefore, Segment Adjusted EBITDA is presented in conformity with ASC 280, Segment Reporting. Segment Adjusted EBITDA is defined as earnings (loss) from operations before interest, income tax expense (benefit), depreciation and amortization (“EBITDA”) adjusted to exclude net other income (expense).
Corporate and unallocated expenses includes global facilities and information technology costs and long-term product roadmap expenses in addition to corporate overhead costs that are not allocated to reportable segments. The overhead costs relate to human resources, finance, legal, accounting, and merger and acquisition activity. These costs along with depreciation and amortization and stock-based compensation are not considered when management evaluates segment performance.

11. Income Taxes
For the three and nine months ended September 30, 2023, the Company's effective tax rate was 19% and 83%, respectively. The Company reported a tax charge on pretax income for the three months ended September 30, 2023 and a tax benefit on pretax loss for the nine months ended September 30, 2023, with foreign entities recognizing earnings of $47.9 million and $64.9 million, respectively.
For the three and nine months ended September 30, 2022, the Company's effective tax rate was 31% and 29%, respectively. The Company reported tax expense on pretax income for both the three and nine months ended September 30, 2022, with foreign entities recognizing earnings of $28.7 million and $87.0 million, respectively.
On July 21, 2023, the Internal Revenue Service issued Notice 2023-55 providing guidance to taxpayers in determining whether a foreign tax is eligible for a U.S. foreign tax credit for tax years 2022 and 2023 effectively delaying the application of an unfavorable foreign tax credit regulation until 2024. As a result of this guidance, the Company recorded a tax benefit of $6.0 million during the three months ended September 30, 2023.
The Company’s effective tax rate could fluctuate on a quarterly basis due to the occurrence of significant and unusual or infrequent items, such as vesting of stock-based compensation or foreign currency gains and losses. 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.
As of September 30, 2023, and December 31, 2022, the amount of unrecognized tax benefits for uncertain tax positions was $22.7 million and $26.4 million, respectively, excluding related liabilities for interest and penalties of $0.6 million.
The Company believes it is reasonably possible that the total amount of unrecognized tax benefits will decrease within the next 12 months by approximately $4.6 million, due to the settlement of various audits and the expiration of statutes of limitation.
12. Commitments and Contingencies
Legal Proceedings
In April 2021, ACH files associated with one of the Company's mortgage servicing customers were inadvertently transmitted into the ACH network during a test of the Company's payment processing system. The Company took immediate corrective action and issued reversing ACH files, restoring affected accounts.
The Company was named as a defendant in seven class action lawsuits filed in various federal courts purportedly on behalf of consumers whose mortgage accounts were affected by the inadvertent ACH file transmission. The Company settled these lawsuits by establishing a $5.0 million fund out of which payments will be made to class members and for attorneys’ fees and administrative costs. The $5.0 million was funded from insurance. Additional funds totaling $1.5 million could be required to be established under certain circumstances.
The inadvertent ACH file transmission also gave rise to investigations by the U.S. Consumer Financial Protection Bureau (the "CFPB") and state attorneys general in all 50 states, the District of Columbia, and certain U.S. territories as well as money transmission regulators in most of those jurisdictions. The Company settled the CFPB investigation for $25.0 million plus various undertakings. Payment was made to the CFPB and funds received from the insurance carriers during the three months ended September 30, 2023. Subsequent to September 30, 2023, the Company settled with the state money transmission regulators and attorneys general for a total of $20.0 million plus various undertakings. Funds for the state and money transmission regulator settlements were previously received from the insurance carriers and deposited into an escrow account. The Company believes that the CPFB and state undertakings will not adversely affect it.

The Company’s customer commenced an action for damages as a result of this event. The customer action remains pending and the Company presently intends to vigorously defend it. The Company expects that insurance will fund payments and costs associated with the defense of the customer action, and other claims that may be asserted against it, subject to the policy limits and other terms of the applicable policies.
Funds received from or expected to be received from insurance carriers are generally subject to the respective carriers' reservation of rights.
The Company is from time to time subject to other claims, litigation and investigations. While the Company believes that none of the currently pending matters is reasonably likely to have material adverse effect on it, there can be no assurance with respect thereto or future matters.

Many of these factors will be important in determining our actual future results. Any or all of the forward-looking statements in this report may turn out to be incorrect. They may be based on inaccurate assumptions or may not account for known or unknown risks and uncertainties. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially from those expressed or implied in any forward-looking statements, and our business, financial condition and results of operations could be materially and adversely affected. In addition, we disclaim any obligation to update any forward-looking statements after the date of this report, except as required by law.
All forward-looking statements in this report are expressly qualified by the risk factors discussed in our filings with the Securities and Exchange Commission (“SEC”). The cautionary statements in this report expressly qualify all of our forward-looking statements. Factors that could cause actual results to differ from those expressed or implied in the forward-looking statements include, but are not limited to, those discussed in our Risk Factors in Part 1, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, and in Part 2, Item 1A of this Form 10-Q.
The following discussion should be read together with our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, and with our financial statements and related notes contained in this Form 10-Q. Results for the three and nine months ended September 30, 2023, are not necessarily indicative of results that may be attained in the future.
Global Economy and Inflation
Since 2022, the global economy has experienced high inflation, increased interest rates, and pressures on gross domestic product. While we believe our business is resilient and can generally weather unusually high levels of inflation, inflationary pressures have had some impact on our financial performance. Specifically, inflation has impacted our interchange costs associated with the Biller segment.
Overview
ACI Worldwide powers digital payments for more than 6,000 organizations around the world. More than 1,000 of the largest banks and intermediaries, as well as thousands of global merchants, rely on ACI to execute $14 trillion each day in payments and securities. In addition, myriad organizations utilize our electronic bill presentment and payment services. Through our comprehensive suite of software solutions delivered on customers' premises, through the public cloud or through ACI's private cloud, we provide real-time, immediate payments capabilities and enable the industry's most complete omni-channel payments experience.
Our products are sold and supported directly and through distribution networks covering three geographic regions – the Americas; Europe, Middle East, and Africa (“EMEA”); and Asia Pacific. Each region has a globally coordinated sales force, supplemented with local independent reseller and/or distributor networks. Our products and solutions are used globally by banks and intermediaries, merchants, and billers, such as third-party electronic payment processors, payment associations, switch interchanges, and a wide range of transaction-generating endpoints, including ATMs, merchant point-of-sale (“POS”) terminals, bank branches, mobile phones, tablets, corporations, and internet commerce sites. Accordingly, our business and operating results are influenced by trends such as information technology spending levels, the growth rate of digital payments, mandated regulatory changes, and changes in the number and type of customers in the financial services industry, as well as economic growth and purchasing habits. Our products are marketed under the ACI Worldwide brand.
We derive a majority of our revenues from domestic operations and believe we have large opportunities for growth in international markets, as well as continued expansion domestically in the United States. Refining our global infrastructure is a critical component of driving our growth. We also continue to maintain centers of expertise in Timisoara, Romania and Pune and Bangalore in India, as well as key operational centers such as in Cape Town, South Africa and in multiple locations in the United States.

Table of contents
Key trends that currently impact our strategies and operations include:
Increasing digital payment transaction volumes. The adoption of digital payments continues to accelerate, propelled by the digitization of cash, financial inclusion efforts of countries throughout the world, the Internet of Things, rapid growth of eCommerce and the adoption of real-time payments. COVID-19 further accelerated this growth as more people, governments, and businesses embraced digital payments - a change likely to continue. We leverage the growth in transaction volumes through the licensing of new systems to customers whose older systems cannot handle increased volume, through the sale of capacity upgrades to existing customers, and through the scalability of our platform-based solutions.
Adoption of real-time payments. Expectations from both consumers and businesses are continuing to drive the payments world to more real-time delivery. This is bolstered by the new data-rich ISO 20022 messaging format, which is delivering greater value to banks and their customers. We are seeing global players with existing schemes working to expand capacity in anticipation of volume growth and new payment types. Mature markets, including India, the United Kingdom, Australia, Malaysia, Singapore, Thailand, and the Nordics, continue to accelerate innovation, especially in terms of overlay services and cross-border connectivity. The United States is driving real-time payments adoption through Zelle, TCH Real-Time Payments, and the planned FedNow service. We are seeing success with real-time payments in the Middle East as well, as they have started to renovate their payment systems from legacy payment types to the modern digital and real-time world. ACI's broad software portfolio, experience, and strategic partnerships with Mastercard, Microsoft, and Mindgate Solutions continue to position us as a leader in real-time payments, helping to drive seamless connectivity, increased security, and end-to-end modernization for organizations throughout the world.
Adoption of cloud technology. ACI has recognized the industry's technical inflection point in the transition from traditional on-premise infrastructure to the public cloud, and we are supporting our customers' cloud strategies. Public and private cloud technology innovations allow the financial services ecosystem to accelerate innovation and ensure scalability and resiliency while improving operating economics over time. As banks and intermediaries, merchants, and billers seek to transition their systems to make use of cloud technology, our investments and partnerships, as demonstrated by our product enablement and initial optimization onto Microsoft Azure, enable us to leverage those cloud technology benefits today and for the future while preserving ACI's fundamental base of performance, resiliency, and scalability.
Payments intelligence, fraud, and compliance. The accelerated adoption of real-time payments increases the urgency for industry-wide collaboration against fraud. As the threat of scams becomes a greater concern for emitting and receiving institutions, consumers are challenged with increased friction to prevent account take-over and criminals successfully persuading consumers to push transactions themselves, inadvertently, to mule accounts they have full control of, created with fake or synthetic identity, or simply "borrowed" with or without consent of the legit account holders. Regulators are beginning to litigate between consumers and financial institutions on the losses, and between emitting and receiving banks on the accountability for reimbursement. Banks and intermediaries, merchants, and billers are pursuing solutions to mitigate their risks while improving their customer experience, protecting their margins, and securing their revenue streams, especially with their new products and offerings. We continue to see opportunity for our advanced machine learning and network intelligence capabilities to stop criminals and enable frictionless legitimate business.
Omni-commerce. Shoppers are increasingly browsing, buying, and returning items across channels, including in-store, online, and mobile. COVID-19 accelerated this trend, leading to an increase in contactless payments, click and collect, and curbside collection. Merchants from all industries, including grocers, fuel and convenience stores, are being tasked with delivering seamless experiences that include pay-in-aisle, kiosks, mobile app payments, QR code payments, eCommerce, traditional and mobile POS, buy online pickup in-store (BOPIS) and buy online return in-store (BORIS). We believe there is significant opportunity to provide merchants with the tools to deliver a seamless, secure, personalized experience that creates loyalty and satisfaction, and drives conversion rates while protecting consumer data and preventing fraud.
Request for Payment (RfP). Markets across the world are introducing an innovative payments service called Request for Payment (RfP). This technology is known by different names in different markets: Collect payments in India, Request 2 Pay in Europe, Request To Pay (RTP) in the United Kingdom, or Request for Payment (RfP) in the United States. RfP offers secure messaging between consumers and billers or merchants, wherein a biller or merchant can request a payment from a consumer through the use of a trusted app, most likely a banking app. RfP is primarily being implemented on top of real-time payments, which are continuing to grow and flourish as countries around the world develop and launch their real-time schemes as noted above. ACI is in a unique position to deliver this overlay service given our real-time payments software, our relationships with banks, merchants and billers, and global real-time connectivity.

Table of contents
Several other factors related to our business may have a significant impact on our operating results from year to year. For example, the accounting rules governing the timing of revenue recognition are complex, and it can be difficult to estimate when we will recognize revenue generated by a given transaction. Factors such as creditworthiness of the customer and timing of transfer of control or acceptance of our products may cause revenues related to sales generated in one period to be deferred and recognized in later periods. For arrangements in which services revenue is deferred, related direct and incremental costs may also be deferred. Additionally, while the majority of our contracts are denominated in the U.S. dollar, a substantial portion of our sales are made, and some of our expenses are incurred, in the local currency of countries other than the United States. Fluctuations in currency exchange rates in a given period may result in the recognition of gains or losses for that period.
We continue to seek ways to grow through organic sources, partnerships, alliances, and acquisitions. We continually look for potential acquisitions designed to improve our solutions’ breadth or provide access to new markets. As part of our acquisition strategy, we seek acquisition candidates that are strategic, capable of being integrated into our operating environment, and accretive to our financial performance.
Divestiture
On September 1, 2022, we sold our corporate online banking solutions related assets and liabilities to One Equity Partners ("OEP") for $100.0 million, including a net working capital adjustment. The sale included employees and customer contracts as well as technology assets and intellectual property.
The Company recognized a gain of $38.5 million on the sale during the three and nine months ended September 30, 2022. During the nine months ended September 30, 2023, the Company recognized a loss for the final post-closing adjustment pursuant to the definitive agreement of $0.5 million.
The Company and OEP have also entered into a Transition Services Agreement ("TSA"), whereby the Company will continue to perform certain functions on OEP's behalf during a migration period not expected to exceed 18 months. The TSA is meant to reimburse the Company for direct costs in order to provide such functions, which are no longer generating revenue for the Company.
Backlog
Backlog is comprised of:
•Committed Backlog, which includes (1) contracted revenue that will be recognized in future periods (contracted but not recognized) from software license fees, maintenance fees, service fees, and SaaS and PaaS fees specified in executed contracts (including estimates of variable consideration if required under ASC 606, Revenue From Contracts With Customers) and included in the transaction price for those contracts, which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods and (2) estimated future revenues from software license fees, maintenance fees, services fees, and SaaS and PaaS fees specified in executed contracts.
•Renewal Backlog, which includes estimated future revenues from assumed contract renewals to the extent we believe recognition of the related revenue will occur within the corresponding backlog period.
We have historically included assumed renewals in backlog estimates based upon automatic renewal provisions in the executed contract and our historic experience with customer renewal rates.
25

Table of contents
Our 60-month backlog estimates are derived using the following key assumptions:
•License arrangements are assumed to renew at the end of their committed term or under the renewal option stated in the contract at a rate consistent with historical experience. If the license arrangement includes extended payment terms, the renewal estimate is adjusted for the effects of a significant financing component.
•Maintenance fees are assumed to exist for the duration of the license term for those contracts in which the committed maintenance term is less than the committed license term.
•SaaS and PaaS arrangements are assumed to renew at the end of their committed term at a rate consistent with our historical experiences.
•Foreign currency exchange rates are assumed to remain constant over the 60-month backlog period for those contracts stated in currencies other than the U.S. dollar.
•Our pricing policies and practices are assumed to remain constant over the 60-month backlog period.
In computing our 60-month backlog estimate, the following items are specifically not taken into account:
•Anticipated increases in transaction, account, or processing volumes by our customers.
•Optional annual uplifts or inflationary increases in recurring fees.
•Services engagements, other than SaaS and PaaS arrangements, are not assumed to renew over the 60-month backlog period.
•The potential impact of consolidation activity within our markets and/or customers.
We review our customer renewal experience on an annual basis. The impact of this review and subsequent updates may result in a revision to the renewal assumptions used in computing the 60-month backlog estimates. In the event a significant revision to renewal assumptions is determined to be necessary, prior periods will be adjusted for comparability purposes.
The following table sets forth our 60-month backlog estimate, by reportable segment, as of September 30, 2023, June 30, 2023, March 31, 2023, and December 31, 2022 (in millions).

Estimates of future financial results require substantial judgment and are based on several assumptions, as described above. These assumptions may turn out to be inaccurate or wrong for reasons outside of management’s control. For example, our customers may attempt to renegotiate or terminate their contracts for many reasons, including mergers, changes in their financial condition, or general changes in economic conditions in the customer’s industry or geographic location. We may also experience delays in the development or delivery of products or services specified in customer contracts, which may cause the actual renewal rates and amounts to differ from historical experiences. Changes in foreign currency exchange rates may also impact the amount of revenue recognized in future periods. Accordingly, there can be no assurance that amounts included in backlog estimates will generate the specified revenues or that the actual revenues will be generated within the corresponding 60-month period. Additionally, because certain components of Committed Backlog and all of Renewal Backlog estimates are operating metrics, the estimates are not required to be subject to the same level of internal review or controls as contracted but not recognized Committed Backlog.

License Revenue
Customers purchase the right to use ACI software under multi-year, time-based software license arrangements that vary in length but are generally five years. Under these arrangements the software is installed at the customer’s location (i.e. on-premise). Within these agreements are specified capacity limits typically based on customer transaction volume. ACI employs measurement tools that monitor the number of transactions processed by customers and if contractually specified limits are exceeded, additional fees are charged for the overage. Capacity overages may occur at varying times throughout the term of the agreement depending on the product, the size of the customer, and the significance of customer transaction volume growth. Depending on specific circumstances, multiple overages or no overages may occur during the term of the agreement.
Included in license revenue are license and capacity fees that are payable at the inception of the agreement or annually (initial license fees). License revenue also includes license and capacity fees payable quarterly or monthly due to negotiated customer payment terms (monthly license fees). The Company recognizes revenue in advance of billings for software license arrangements with extended payment terms and adjusts for the effects of the financing component, if significant.

Liquidity and Capital Resources
General
Our primary liquidity needs are: (i) to fund normal operating expenses; (ii) to meet the interest and principal requirements of our outstanding indebtedness; and (iii) to fund acquisitions, capital expenditures, and lease payments. We believe these needs will be satisfied using cash flow generated by our operations, our cash and cash equivalents, and available borrowings under our revolving credit facility over the next 12 months and beyond.
Cash and cash equivalents consist of highly liquid investments with original maturities of three months or less. As of September 30, 2023, we had $139.5 million of cash and cash equivalents, of which $40.1 million was held by our foreign subsidiaries. If these funds were needed for our operations in the U.S., we may potentially be required to accrue and pay foreign and U.S. state income taxes to repatriate these funds. As of September 30, 2023, only the earnings in our Indian foreign subsidiaries are indefinitely reinvested. The earnings of all other foreign entities are no longer indefinitely reinvested. We are also permanently reinvested for outside book/tax basis difference related to foreign subsidiaries. These outside basis differences could reverse through sales of the foreign subsidiaries, as well as various other events, none of which are considered probable as of September 30, 2023.
Available Liquidity
The following table sets forth our available liquidity for the dates indicated (in thousands):

| September 30, 2023 |  | December 31, 2022
Cash and cash equivalents | $ | 139,520 |  |  | $ | 124,981 |
Availability under revolving credit facility | 368,200 |  |  | 393,500 |
Total liquidity | $ | 507,720 |  |  | $ | 518,481 |

The Company and ACI Payments, Inc., a wholly owned subsidiary, maintain a $75.0 million uncommitted overdraft facility with Bank of America, N.A. The overdraft facility acts as a secured loan under the terms of the Credit Agreement to provide an additional funding mechanism for timing differences that can occur in the bill payment settlement process. As of September 30, 2023, the full $75.0 million was available.
Stock Repurchase Program
Our board approved a stock repurchase program authorizing the Company, as market and business conditions warrant, to acquire its common stock and periodically authorizes additional funds for the program. On February 24, 2023, the board approved the repurchase of the Company's common stock of up to $200.0 million in place of the remaining purchase amounts previously authorized.
We did not repurchase any shares under the program during the nine months ended September 30, 2023. Under the program to date, we have repurchased 57,981,733 shares for approximately $926.2 million. As of September 30, 2023, the maximum remaining amount authorized for purchase under the stock repurchase program was approximately $200.0 million.

Table of contents
Cash Flows from Operating Activities
The primary source of operating cash flows is cash collections from our customers for purchase and renewal of licensed software products and various services including software and platform as a service, maintenance, and other professional services. Our primary uses of operating cash flows includes employee expenditures, taxes, interest payments, and leased facilities.
Cash flows provided by operating activities were $19.2 million lower for the nine months ended September 30, 2023, compared to the same period in 2022. Our operating cash flows for the current year decreased primarily due to $18.9 million more in income tax payments, which are based upon higher pre-tax income in the previous year, $21.4 million more in interest payments due to increase in interest rates, and the net loss for the nine months ended September 30, 2023, compared to net income for the same period in 2022, partially offset by $36.2 million more in customer receipt collections on higher prior year-end receivable balances.
Our cash flow from operating activities can fluctuate from period to period due to several factors, including: the timing of billings, which are typically higher in the third and fourth quarters in conjunction with sales timing and are variable based upon license renewal timing; collections, which will lag the quarters with higher billings; the timing and amounts of interest due to interest rate fluctuations and semi-annual Senior Notes interest payments; income tax and other payments; and our operating results.
Cash Flows from Investing Activities
The changes in cash flows from investing activities primarily relate to the timing of our purchases and investments in capital and other assets, including strategic acquisitions, that support our growth.
During the first nine months of 2023, we used cash of $30.5 million to purchase software, property, and equipment, as compared to $26.5 million during the same period in 2022. During the first nine months of 2022, we received net proceeds of $100.1 million from the divestiture.
Cash Flows from Financing Activities
The changes in cash flows from financing activities primarily relate to borrowings and repayments related to our debt instruments and other debt, stock repurchases, and net proceeds related to employee stock programs.
During the first nine months of 2023, we repaid $53.6 million on the Term Loans, $12.5 million of other debt payments, and $2.2 million of debt issuance costs. In addition, we used $4.2 million for the repurchase of stock-based compensation awards for tax withholdings, and $4.6 million for settlement assets and liabilities due to processing timing. We received net proceeds of $24.0 million on the Revolving Credit Facility, and proceeds of $5.3 million from the exercise of stock options and the issuance of common stock under our 2017 Employee Stock Purchase Plan, as amended. During the first nine months of 2022, we used the proceeds from the divestiture to partially fund repayments of $70.8 million on the Term Loans and $10.1 million of other debt payments. In addition, we used $90.9 million to repurchase common stock and $5.8 million for the repurchase of stock-based compensation awards for tax withholdings. We received net proceeds of $10.0 million on the Revolving Credit Facility, proceeds of $4.6 million from the exercise of stock options and the issuance of common stock under our 2017 Employee Stock Purchase Plan, as amended, and $20.1 million from settlement assets and liabilities due to processing timing.
Contractual Obligations and Commercial Commitments
For the nine months ended September 30, 2023, there have been no material changes to the contractual obligations and commercial commitments disclosed in Item 7 of our Form 10-K for the fiscal year ended December 31, 2022.
Critical Accounting Estimates
The preparation of the condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and other assumptions we believe to be proper and reasonable under the circumstances. We continually evaluate the appropriateness of estimates and assumptions used in the preparation of our condensed consolidated financial statements. Actual results could differ from those estimates.
38

Table of contents
The accounting policies that reflect our more significant estimates, judgments, and assumptions, and that we believe are the most critical to aid in fully understanding and evaluating our reported financial results, include the following:
•Revenue Recognition
•Intangible Assets and Goodwill
•Business Combinations
•Stock-Based Compensation
•Accounting for Income Taxes
During the nine months ended September 30, 2023, there were no significant changes to our critical accounting policies and estimates. Please refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in Part II, Item 7 of our Annual Report on Form 10-K for our fiscal year ended December 31, 2022, for a more complete discussion of our critical accounting policies and estimates.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Excluding the impact of changes in interest rates, inflationary pressures, and the uncertainty in the global financial markets, there have been no material changes to our market risk for the nine months ended September 30, 2023. We conduct business in all parts of the world and are thereby exposed to market risks related to fluctuations in foreign currency exchange rates. The U.S. dollar is the single largest currency in which our revenue contracts are denominated. Any decline in the value of foreign currencies against the U.S. dollar results in our products and services being more expensive to a potential foreign customer. In those instances where our goods and services have already been sold, receivables may be more difficult to collect. Additionally, in jurisdictions where the revenue contracts are denominated in U.S. dollars and operating expenses are incurred in the local currency, any decline in the value of the U.S. dollar will have an unfavorable impact to operating margins. At times, we enter into revenue contracts that are denominated in the country’s local currency, primarily in Australia, Canada, the United Kingdom, other European countries, Brazil, India, and Singapore. This practice serves as a natural hedge to finance the local currency expenses incurred in those locations. We have not entered into any foreign currency hedging transactions. We do not purchase or hold any derivative financial instruments for speculation or arbitrage.
The primary objective of our cash investment policy is to preserve principal without significantly increasing risk. If we maintained similar cash investments for a period of one year based on our cash investments and interest rates on these investments at September 30, 2023, a hypothetical ten percent increase or decrease in effective interest rates would increase or decrease interest income by $0.1 million annually.
We had approximately $1.1 billion of debt outstanding as of September 30, 2023, with $668.2 million outstanding under our Credit Facility and $400.0 million in 2026 Notes. Our Credit Facility has a floating rate, which was 7.42% as of September 30, 2023. Our 2026 Notes are fixed-rate long-term debt obligations with a 5.750% interest rate. A hypothetical ten percent increase or decrease in effective interest rates would increase or decrease interest expense related to the Credit Facility by approximately $5.0 million.
ITEM 4. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
Management, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, performed an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded our disclosure controls and procedures are effective as of September 30, 2023.
Changes in Internal Control over Financial Reporting
There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) under the Exchange Act) during the quarter ended September 30, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
See Note 12 , Commitments and Contingencies, to our unaudited condensed consolidated financial statements in Part I of this Form 10-Q for additional information regarding legal proceedings.
ITEM 1A. RISK FACTORS
There have been no material changes to the risk factors disclosed in Item 1A of our Form 10-K for the fiscal year ended December 31, 2022, other than as described below. Additional risks and uncertainties, including risks and uncertainties not presently known to us, or that we currently deem immaterial, could also have an adverse effect on our business, financial condition and/or results of operations.
We are involved in investigations, lawsuits and other proceedings that are expensive, time-consuming and could seriously harm to our business.
We are involved in lawsuits, including class-action lawsuits, and government investigations relating to the conduct of our business. For example, in April 2021, ACH files associated with one of our mortgage servicing customers were inadvertently transmitted into the ACH network during a test of our payment processing system. We took immediate corrective action and issued reversing ACH files, restoring affected accounts. Private plaintiffs initiated seven class action lawsuits, the Consumer Financial Protection Bureau, state regulators and state attorneys general initiated investigations and our customer commenced an action for damages as a result of this event. We have settled the class action lawsuits and the investigations by federal and state regulatory authorities and state attorneys general arising out of the event. The customer action remains pending and we presently intend to vigorously defend it. We expect that insurance will fund substantially all of the payments and costs associated with these settlements, including lawyers’ fees as well as the defense of the customer action, and any other claims that may be asserted against it or that it may assert arising from the event, subject to the retained limits and other terms of the applicable policies. See Legal Proceedings in Note 12, Commitments and Contingencies, to our Notes to Consolidated Financial Statements in Part I, Item 1 of this Form 10-Q for a discussion of these matters.
Damage claims in lawsuits, and fines and penalties imposed by governmental agencies, can be substantial, and injunctive or other remedies imposed by governmental agencies can be costly to implement. Any litigation may result in an onerous or unfavorable judgment that might not be reversed on appeal, or we may decide to settle lawsuits or resolve government investigations on adverse terms. Any such negative outcomes could result in the payment of substantial monetary damages or penalties that are not funded by insurance or require changes to our products or business practices that materially affect us. Even where the ultimate outcome of any such litigation or regulatory proceeding may be favorable, defending against claims and responding to regulatory proceedings is costly and can impose a significant burden on us.
The existence of lawsuits and investigations, and any adverse outcome, may create negative publicity for the Company and undermine our goodwill with customers. Competitors may use these lawsuits and investigations against us in the marketplace, making it difficult for us to attract new customers and retain our existing customers.
We are subject to consent orders and other compliance agreements (the “Consent Orders and Compliance Agreements ”) entered into in connection with the settlement of state and federal regulators’ investigations. Failure to comply with the Consent Orders and Compliance Agreements could result in further, and more significant, enforcement actions against us.
We are required to conduct our operations in compliance with the Consent Orders and Compliance Agreements. While we have complied with the Consent Orders and Compliance Agreements, and have implemented processes by which we believe we will maintain compliance with the Consent Orders and Compliance Agreements going forward, we cannot be certain that we will maintain compliance with the Consent Orders and Compliance Agreements in all instances. In the event that we are deemed to be non-compliant with the terms of the Consent Orders and/or Compliance Agreements, the state and/or federal regulators have the authority to subject us to additional, and potentially more significant, corrective actions and could seek to initiate further enforcement actions against us, including seeking civil money penalties. Any failure by us to comply with the terms of the Consent Orders and Compliance Agreements or additional actions could adversely affect our business, financial condition and results of operations. In addition, our competitors may not be subject to similar actions, which could limit our ability to compete effectively.

Issuer Purchases of Equity Securities
The following table provides information regarding our repurchases of common stock during the three months ended September 30, 2023:

Period | Total Number of Shares Purchased |  | Average Price Paid per Share |  | Total Number of Shares Purchased as Part of Publicly Announced Program |  | Approximate Dollar Value of Shares that May Yet Be Purchased Under the Program
July 1, 2023 through July 31, 2023 | — |  |  | $ | — |  |  | — |  |  | $ | 200,000,000 |
August 1, 2023 through August 31, 2023 | 37,479 |  | (1) | 23.53 |  |  | — |  |  | 200,000,000 |
September 1, 2023 through September 30, 2023 | 63 |  | (1) | 22.14 |  |  | — |  |  | 200,000,000 |
Total | 37,542 |  |  | $ | 23.53 |  |  | — |  |  |

(1)Pursuant to our 2016 and 2020 Equity and Performance Incentive Plan, we granted RSUs. Under each arrangement, shares are issued without direct cost to the employee. During the three months ended September 30, 2023, 114,948 shares of RSUs vested. We withheld 37,542 of those shares to pay the employees’ portion of the applicable minimum payroll withholding.
In 2005, our board approved a stock repurchase program authorizing us, as market and business conditions warrant, to acquire our common stock and periodically authorize additional funds for the program, with the intention of using existing cash and cash equivalents to fund these repurchases. On February 24, 2023, the board approved the repurchase of the Company's common stock of up to $200.0 million, in place of the remaining purchase amounts previously authorized. As of September 30, 2023, the maximum remaining amount authorized for purchase under the stock repurchase program was approximately $200.0 million.
There is no guarantee as to the exact number of shares we will repurchase. Repurchased shares are returned to the status of authorized but unissued shares of common stock. In March 2005, our board approved a plan under Rule 10b5-1 of the Securities Exchange Act of 1934 to facilitate the repurchase of shares of common stock under the existing stock repurchase program. Under our Rule 10b5-1 plan, we have delegated authority over the timing and amount of repurchases to an independent broker who does not have access to inside information about the Company. Rule 10b5-1 allows us, through the independent broker, to purchase shares at times when we ordinarily would not be in the market because of self-imposed trading blackout periods, such as the time immediately preceding the end of the fiscal quarter through a period of three business days following our quarterly earnings release.

As previously reported in the original Form 8-K, at the Annual Meeting a non-binding, advisory vote was taken on the frequency of future advisory votes regarding the compensation of our named executive officers. Among the options presented to stockholders (every year, every two years or every three years), the greatest number of votes were cast in favor of holding such an advisory vote every year, which was also the frequency recommended to the stockholders by the Company’s board of directors. In light of these results and consistent with the previous recommendation and determination of the Company’s board of directors, we will continue to hold a non-binding advisory vote on executive compensation every year until the next required vote on the frequency of stockholder votes on executive compensation.
