Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Financial Commitments As discussed in Note 7 — Equity Method Investments, we are committed to making annual capital contributions in TailFin Labs of $35.0 million per year from January 2020 through January 2024. Litigation and Claims In the ordinary course of business, we are a party to various legal proceedings, including, from time to time, actions which are asserted to be maintainable as class action suits. We review these actions on an ongoing basis to determine whether it is probable and estimable that a loss has occurred and use that information when making accrual and disclosure decisions. We have provided reserves where necessary for all claims and, based on current knowledge and in part upon the advice of legal counsel, all matters are believed to be adequately covered by insurance, or, if not covered, we do not expect the outcome in any legal proceedings, individually or collectively, to have a material adverse impact on our financial condition or results of operations. On December 18, 2019, an alleged class action entitled Koffsmon v. Green Dot Corp., et al., No. 19-cv-10701-DDP-E, was filed in the United States District Court for the Central District of California, against us and two of our former officers. The suit asserts purported claims under Sections 10(b) and 20(a) of the Exchange Act for allegedly misleading statements regarding our business strategy. Plaintiff alleges that defendants made statements that were misleading because they allegedly failed to disclose details regarding our customer acquisition strategy and its impact on our financial performance. The suit is purportedly brought on behalf of purchasers of our securities between May 9, 2018 and November 7, 2019, and seeks compensatory damages, fees and costs. Note 17—Commitments and Contingencies (continued) On October 6, 2021, the Court appointed the New York Hotel Trades Council & Hotel Association of New York City, Inc. Pension Fund as lead plaintiff, and on April 1, 2022, plaintiff filed its First Amended Complaint. Defendants filed a motion to dismiss the First Amended Complaint on May 31, 2022, and the motion was heard on December 12, 2022. On February 18, 2020, a shareholder derivative suit and securities class action entitled Hellman v. Streit, et al., No. 20-cv-01572-SVW-PVC was filed in United States District Court for the Central District of California, against us and certain of our officers and directors. The suit avers purported breach of fiduciary duty and unjust enrichment claims, as well as claims under Sections 10(b), 14(a) and 20(a) of the Exchange Act, on the basis of the same wrongdoing alleged in the first lawsuit described above. The suit does not define the purported class allegedly damaged. These cases have been related and, pursuant to a stipulated agreement between the parties, the Hellman suit is stayed pending resolution of any motions to dismiss in the Koffsmon case reference above, after which time the parties will meet and confer on a case schedule, including the schedule for defendants to respond to the complaint. We have not yet responded to the complaints in these matters. Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of these matters. Given the uncertainty of litigation and the preliminary stage of these claims, we are currently unable to estimate the probability of the outcome of these actions or the range of reasonably possible losses, if any, or the impact on our results of operations, financial condition or cash flows, except as disclosed. Other Legal Matters We monitor the laws of all 50 states to identify state laws or regulations that apply (or may apply) to our products and services. We have obtained money transmitter licenses (or similar such licenses) where applicable, based on advice of counsel or when we have been requested to do so. If we were found to be in violation of any laws and regulations governing banking, money transmitters, electronic fund transfers, or money laundering in the United States or abroad, we could be subject to penalties or could be forced to change our business practices. From time to time, we enter into contracts containing provisions that contingently require us to indemnify various parties against claims from third parties. These contracts primarily relate to: (i) contracts with our card issuing banks, under which we are responsible to them for any unrecovered overdrafts on cardholders’ accounts; (ii) certain real estate leases, under which we may be required to indemnify property owners for environmental and other liabilities, and other claims arising from our use of the premises; (iii) certain agreements with our officers, directors, and employees, under which we may be required to indemnify these persons for liabilities arising out of their relationship with us; and (iv) contracts under which we may be required to indemnify our retail distributors, suppliers, vendors and other parties with whom we have contracts against claims arising from certain of our actions, omissions, violations of law and/or infringement of patents, trademarks, copyrights and/or other intellectual property rights. Generally, a maximum obligation under these contracts is not explicitly stated. Because the obligated amounts associated with these types of agreements are not explicitly stated, the overall maximum amount of the obligation cannot be reasonably estimated. With the exception of overdrafts on cardholders’ accounts, historically, we have not been required to make payments under these and similar contingent obligations, and no liabilities have been recorded for these obligations in our consolidated balance sheets. For additional information regarding overdrafts on cardholders’ accounts, refer to Note 5 — Accounts Receivable.
