Commitments and Contingencies Disclosure [Abstract]
Legal Contingencies	Legal Contingencies There have been no material changes in the status of the legal proceedings previously disclosed in Part II, Item 8, "Note 21 - Commitments and Contingent Liabilities" of the Company's Annual Report on Form 10-K for the year ended December 31, 2021, except as follows. From time to time, the Company and its subsidiaries are involved in various legal proceedings incidental to their business in the ordinary course, including matters in which damages in various amounts are claimed. Based on information currently available, the Company does not believe that the liabilities (if any) resulting from such legal proceedings will have a material effect on the financial position of the Company. However, in light of the inherent uncertainties involved in such matters, ongoing legal expenses or an adverse outcome in one or more of these matters could materially and adversely affect the Company's financial condition, results of operations or cash flows in any particular reporting period, as well as its reputation. As previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2021, on February 10, 2022, the United States District Court for the Southern District of New York (the "SDNY") approved the settlement agreement of a putative class action lawsuit filed against the Company, its current and former President and Chief Executive Officer and its current and former Chief Financial Officer. The settlement included a total payment by the Company of $7.5 million in exchange for the release of all of the defendants from all alleged claims in the class action suit, without any admission or concession of wrongdoing by the Company or the other defendants. In connection with the previously disclosed investigation by the SEC, the Company's discussions with the Staff have progressed, and the Company continues to engage with the Staff, including senior Staff members, about a potential resolution or settlement of the Staff's investigation with respect to the Company. The Company is hopeful that these discussions will lead to a timely resolution of the investigation as it relates to the Company and any current employees and directors on a mutually agreeable basis, but there can be no assurance that will be the case. There also can be no assurance that this would result in resolution of any charges against former employees or directors, given the Staff's ongoing review of the factual record. Any agreements reached by the Company with the Staff would be subject to approval by the Commission, and there can be no assurance that it would be approved. We are unable to predict the outcome of the investigation or these discussions or whether any potential resolution would have a material impact on the Company. The Company is also continuing discussions with the Staff of the Federal Reserve Board about a potential resolution or settlement of its investigation with respect to the Company. With respect to the other investigations described above, we are unable to predict their duration, scope or outcome. As previously disclosed, the Company maintains director and officer insurance policies ("D&O Insurance Policies") that provide coverage for the legal defense costs related to certain of the above-described investigations and litigations and those discussed in the Company's Annual Report on Form 10-K for the year ended December 31, 2021. When claims are covered by D&O Insurance Policies, the Company records a corresponding receivable against the incurred legal defense cost expense subject to coverage under the D&O Insurance Policies and then eliminates the receivable and expense when the claim is paid. Since the commencement of the above-described matters in 2018 through March 31, 2022, the Company's D&O Insurance carriers have advanced a number defense cost claims to the Company and its current and former directors and officers. Subject to any new developments to the above-described investigations and litigations that may occur over the next few months, the Company currently believes there is a possibility that the applicable D&O Insurance Policies may be exhausted as early as the second quarter of 2022. Once the D&O Insurance Policies are exhausted, the Company will be responsible for paying the defense costs associated with the above-described investigations and litigations for itself and on behalf of any current and former Officers and Directors entitled to indemnification from the Company. The Company cannot predict with any certainty the amount of defense costs that the Company may incur in the future in connection with currently ongoing and any potential future investigations and legal proceedings, as they are dependent on various factors, many of which are outside of the Company's control.
