6. COMMITMENTS, GUARANTEES AND CONTINGENCIES Warranties. We generally warrant that our solutions and related offerings will conform to published specifications, or to specifications provided in an individual client arrangement, as applicable. The typical warranty period is 90 days from the date of acceptance of the solution or offering. For certain service offerings we provide a warranty for the duration of the services provided. We generally warrant that services will be performed in a professional and workmanlike manner. The typical remedy for breach of warranty is to correct or replace any defective deliverable, and if not possible or practical, we will accept the return of the defective deliverable and refund the amount paid under the client arrangement that is allocable to the defective deliverable. Our contracts also generally contain limitation of damages provisions in an effort to reduce our exposure to monetary damages arising from breach of warranty claims. Historically, we have incurred minimal warranty costs, and as a result, do not maintain a warranty reserve. Product and Services Indemnifications. Our arrangements with our clients generally include an indemnification provision that will indemnify and defend a client in actions brought against the client that claim our products and/or services infringe upon a copyright, trade secret, or valid patent. Historically, we have not incurred any significant costs related to such indemnification claims, and as a result, do not maintain a reserve for such exposure. Claims for Company Non-performance. Our arrangements with our clients typically cap our liability for breach to a specified amount of the direct damages incurred by the client resulting from the breach. From time-to-time, these arrangements may also include provisions for possible liquidated damages or other financial and contractual remedies for our non-performance, or in the case of certain of our outsourced customer care and billing solutions, provisions for damages related to service level performance requirements. The service level performance requirements typically relate to system availability and timeliness of service delivery. Historically, we have not incurred significant costs associated with service level performance within our client contracts, and as a result, do not include estimates for potential credits or refunds related to service level performance in our contract consideration at the onset of the contract, but instead, account for credits or refunds as an adjustment to the contract consideration as those events occur. Indemnifications Related to Officers and the Board of Directors. We have agreed to indemnify members of our Board of Directors (the Board) and certain of our officers if they are named or threatened to be named as a party to any proceeding by reason of the fact that they acted in such capacity. We maintain directors and officers (D&amp;O) insurance coverage to protect against such losses. We have not historically incurred any losses related to these types of indemnifications, and are not aware of any pending or threatened actions or claims against any officer or member of our Board. As a result, we have not recorded any liabilities related to such indemnifications as of June 30, 2019 . In addition, as a result of the insurance policy coverage, we believe these indemnification agreements are not significant to our results of operations. Prior Year Acquisition. On October 1, 2018, we acquired Forte, a leading provider of advanced payment solutions headquartered in Allen, Texas. We acquired 100% of the equity of Forte for a purchase price of approximately $93 million, (approximately $85 million, excluding cash acquired), of which approximately $13 million of the purchase price was held back subject to certain tax filings, and was paid out in July 2019. The purchase agreement also includes provisions for $18.8 million of potential future earn-out payments over a four-year measurement period. The earn-out payments are tied to performance-based goals and a defined service period by the eligible recipients and is being accounted for as post-acquisition compensation. As of June 30, 2019, we have accrued $2.5 million related to the potential earn-out payments. The estimated fair values of assets acquired and liabilities assumed for the Forte acquisition were considered provisional as of June 30, 2019, as we were awaiting resolution of the tax filings to complete the accounting for deferred income taxes. In July 2019, the income tax matter was resolved. Legal Proceedings. From time-to-time, we are involved in litigation relating to claims arising out of our operations in the normal course of business. We are not presently a party to any material pending or threatened legal proceedings.
