Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies Disclosure [Text Block] | Commitments and Contingent Liabilities Litigation Contingencies As a member of Visa, BOK Financial is obligated for a proportionate share of certain covered litigation losses incurred by Visa under a retrospective responsibility plan. A contingent liability was recognized for the Company’s share of Visa’s covered litigation liabilities. Visa funded an escrow account to cover litigation claims, including covered litigation losses under the retrospective responsibility plan, with proceeds from its initial public offering in 2008 and from available cash. BOK Financial currently owns 252,233 Visa Class B-1 shares (formerly Class B). On January 23, 2024, Visa, Inc. stockholders approved an option to convert up to 50% of our Class B-1 shares to Visa Class C shares and subsequently to freely transferable Visa Class A common shares (the "Exchange Offer") subject to holding periods and certain other conditions contained in the Exchange Offer. The Exchange Offer opened on April 8, 2024, and is scheduled to expire at the end of the day on May 3, 2024. The Company tendered its Class B-1 Visa shares under the Exchange Offer and expects to monetize up to 50% of the Class B-1 shares. Conversion of Class B-1 shares would not reduce our proportionate share of the covered litigation losses which may dilute our remaining Class B shares if the escrow fund is not adequate to cover final litigation costs. BOKF, NA is subject to litigation related to its role as Indenture Trustee for multiple municipal bonds to which Christopher Brogdon acted as borrower. The principal amount of the bonds remaining unpaid at this time is $33 million. Mr. Brogdon is obligated to pay the bonds in full by virtue of a Judgment in the USDC of New Jersey which allows the Securities and Exchange Commission to pursue collection to satisfy the Judgment, which the SEC continues to pursue. The remaining cases are (i) Robert Elliot & Marvin Loeb on behalf of a class of persons purchasing bonds in multiple municipal bond issuances v. BOKF, NA, USDC District of New Jersey, Case No. 2:16-cv-05218-KM-JBC (commenced 11/20/2015); and (ii) Burn Rose, LLC et al v. BOKF, NA d/b/a BOK, Tulsa County District Court Case, No. CJ-2016-03325 (commenced 9/22/2016). In the New Jersey Class Action and the Tulsa County Burn Rose action, the claimants allege that BOKF, NA was complicit in the fraud committed by Mr. Brogdon. BOKF, NA has multiple defenses to the claims, including the defense that it is exculpated by the terms of the various bond indentures. No action has been taken in the class action by the plaintiffs to establish the class and the amount of the damages, if any, cannot be reasonably estimated. Approximately $3 million is claimed as damages in the Burn Rose action. Management is advised that a loss on the claims in both the Class Action and the Burn Rose action is not probable. In the ordinary course of business, BOK Financial and its subsidiaries are subject to legal actions and complaints. Management believes, based upon the opinion of counsel, that the actions and liability or loss, if any, resulting from the final outcomes of the proceedings, will not have a material effect on the Company's financial condition, results of operations or cash flows. Alternative Investment Commitments The Company invests in several tax credit entities and other funds as permitted by banking regulations. Consolidation of these investments is based on the variable interest model. At March 31, 2024, the Company has $405 million in interests in various alternative investments generally consisting of unconsolidated limited partnership interests in entities for which investment return is in the form of low income housing tax credits or other investments in merchant banking activities. These investments are recognized in Other assets on the Consolidated Balance Sheets. This investment balance also includes $99 million of unfunded commitments included in Other liabilities on the Consolidated Balance Sheets.
