Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS, CONTINGENCIES, AND OFF-BALANCE-SHEET ACTIVITIES	COMMITMENTS, CONTINGENCIES, AND OFF-BALANCE-SHEET ACTIVITIES Credit-Related Financial Instruments. The Company is a party to credit-related financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments are commitments to extend credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the unaudited condensed consolidated balance sheets. The Company’s exposure to credit loss is represented by the contractual amount of these commitments. The Company follows the same credit policies in making commitments as it does for on-balance-sheet instruments. At June 30, 2022, the Company had commitments to originate $184.5 million in fixed rate loans and $3,319.8 million in variable rate loans, totaling an aggregate outstanding principal balance of $3,504.3 million. For June 30, 2022, the Company’s fixed rate commitments to originate had a weighted-average rate of 5.75%. For June 30, 2021, the Company had commitments to originate $55.0 million in fixed rate loans and $653.5 million in variable rate loans, totaling an aggregate outstanding principal balance of $708.6 million. For June 30, 2021, the Company’s fixed rate commitments to originate had a weighted-average rate of 1.94%. At June 30, 2022, the Company also had fixed rate commitments to sell loans with an aggregate outstanding principal balance of $8.4 million. For June 30, 2021, the Company had fixed rate and variable rate commitments to sell of $55.9 million. At June 30, 2022 and 2021, 42.3% and 48.2% of the commitments to originate loans are matched with commitments to sell related to conforming single family loans classified as held for sale, respectively. Commitments to extend credit are agreements to lend to a customer so long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments for equity lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management’s credit evaluation of the customer. In addition, we invest in low income housing project partnerships, which provide income tax credits, and in small business investment companies that call for capital contributions up to an amount specified in the partnership agreements. As of June 30, 2022 and 2021, we had commitments to contribute capital to these entities totaling $28.1 million and $15.1 million. In the normal course of business, Axos Clearing’s customer activities involve the execution, settlement, and financing of various customer securities transactions. These activities may expose Axos Clearing to off-balance-sheet risk in the event the customer or other broker is unable to fulfill its contracted obligations and Axos Clearing has to purchase or sell the financial instrument underlying the contract at a loss. Axos Clearing’s clearing agreements with broker-dealers for which it provides clearing services requires them to indemnify Axos Clearing if customers fail to satisfy their contractual obligation. As of June 30, 2022, non-customer and customer margin securities of approximately $324.9 million and stock borrowings of approximately $339.0 million were available to the Company to utilize as collateral on various borrowings or for other purposes. The Company utilized $474.4 million of these available securities as collateral for securities loaned, $186.6 million for bank loans, and $20.0 million for OCC margin requirements. Litigation. On October 15, 2015, the Company, its Chief Executive Officer and its Chief Financial Officer were named defendants in a putative class action lawsuit styled Golden v. BofI Holding, Inc., et al, and brought in United States District Court for the Southern District of California (the “Golden Case”). On November 3, 2015, the Company, its Chief Executive Officer and its Chief Financial Officer were named defendants in a second putative class action lawsuit styled Hazan v. BofI Holding, Inc., et al, and also brought in the United States District Court for the Southern District of California (the “Hazan Case”). On February 1, 2016, the Golden Case and the Hazan Case were consolidated as In re BofI Holding, Inc. Securities Litigation, Case #: 3:15-cv-02324-GPC-KSC (the “Class Action”), and the Houston Municipal Employees Pension System was appointed lead plaintiff. The plaintiffs allege that the Company and other named defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated thereunder, by failing to disclose wrongful conduct that was alleged in a complaint filed in connection with a wrongful termination of employment lawsuit filed on October 13, 2015 (the “Employment Matter”) and that as a result the Company’s statements regarding its internal controls, as well as portions of its financial statements, were false and misleading. On April 13, 2022, the parties executed a Stipulation and Agreement of Settlement. The Stipulation and Agreement of Settlement was submitted to the District Court for approval on April 15, 2022. On June 8, 2022, the court granted preliminary approval of the settlement and scheduled a hearing with respect to final approval of the settlement for October 7, 2022. There is no assurance that final court approval will be granted. The agreed to settlement amount is not material to the Consolidated Financial Statements, as of and for the year ended June 30, 2022. On April 3, 2017, the Company, its Chief Executive Officer and its Chief Financial Officer were named defendants in a putative class action lawsuit styled Mandalevy v. BofI Holding, Inc., et al, and brought in United States District Court for the Southern District of California (the “Mandalevy Case”). The Mandalevy Case seeks monetary damages and other relief on behalf of a putative class that has not been certified by the Court. The complaint in the Mandalevy Case (the “Mandalevy Complaint”) alleges a class period that differs from that alleged in the First Class Action, and that the Company and other named defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated thereunder, by failing to disclose wrongful conduct that was alleged in a March 2017 media article. The Mandalevy Case has not been consolidated into the First Class Action. On December 7, 2018, the Court entered a final order granting the defendants’ motion and dismissing the Mandalevy Case with prejudice. Subsequently, the plaintiff filed a notice of appeal and the Court took the matter under advisement. On November 3, 2020, the Court issued a ruling affirming in part and reversing in part the District Court's Order dismissing the Class Action Second Amended Complaint. The defendants filed a petition for rehearing en banc on November 17, 2020, which petition was denied on December 16, 2020. The defendants filed a motion to dismiss the remanded complaint on February 19, 2021. On January 31, 2022, a Stipulation of Settlement was submitted to the District Court for approval. On May 17, 2022, the court granted preliminary approval of the settlement and scheduled a hearing with respect to final approval for September 23, 2022. There is no assurance that final court approval will be granted. The agreed to settlement amount is not material to the Consolidated Financial Statements, as of and for the year ended June 30, 2022. The Company and the other named defendants dispute the allegations of wrongdoing advanced by the plaintiffs in the Class Action, the Mandalevy Case, and in the Employment Matter, as well as those plaintiffs’ statement of the underlying factual circumstances, and are vigorously defending each case subject to final court approval of the settlements. In addition to the First Class Action and the Mandalevy Case, two separate shareholder derivative actions were filed in December, 2015, purportedly on behalf of the Company. The first derivative action, Calcaterra v. Garrabrants, et al, was filed in the United States District Court for the Southern District of California on December 3, 2015. The second derivative action, Dow v. Micheletti, et al, was filed in the San Diego County Superior Court on December 16, 2015. A third derivative action, DeYoung v. Garrabrants, et al, was filed in the United States District Court for the Southern District of California on January 22, 2016, a fourth derivative action, Yong v. Garrabrants, et al, was filed in the United States District Court for the Southern District of California on January 29, 2016, a fifth derivative action, Laborers Pension Trust Fund of Northern Nevada v. Allrich et al, was filed in the United States District Court for the Southern District of California on February 2, 2016, and a sixth derivative action, Garner v. Garrabrants, et al, was filed in the San Diego County Superior Court on August 10, 2017. Each of these six derivative actions names the Company as a nominal defendant, and certain of its officers and directors as defendants. Each complaint sets forth allegations of breaches of fiduciary duties, gross mismanagement, abuse of control, and unjust enrichment against the defendant officers and directors. The plaintiffs in these derivative actions seek damages in unspecified amounts on the Company’s behalf from the officer and director defendants, certain corporate governance actions, and an award of their costs and attorney’s fees. The United States District Court for the Southern District of California ordered the six above-referenced derivative actions pending before it to be consolidated and appointed lead counsel in the consolidated action. On June 7, 2018, the Court entered an order granting defendant’s motion for judgment on the pleadings, but giving the plaintiffs limited leave to amend by June 28, 2018. The plaintiffs failed to file an amended complaint, and instead plaintiffs filed on June 28, 2018 a motion to stay the case pending resolution of the securities class action and Employment Matter. On August 10, 2018, defendants filed an opposition to plaintiffs’ motion. On September 11, 2018, the plaintiffs filed a second amended complaint. On October 16, 2018, defendants filed a motion to dismiss the second amended complaint. On October 16, 2018, defendants filed a motion to dismiss the second amended complaint. The Court dismissed the second amended complaint with prejudice on May 23, 2019. Subsequently, the plaintiff filed a notice of appeal and opening brief and the Company filed its answering brief. Oral argument was held September 2, 2020. On February 25, 2021, the Ninth Circuit issued a memorandum decision affirming the dismissal of the Calcaterra derivative action. However, the Ninth Circuit reversed the district court’s order denying a stay of the action and remanded to the district court to reconsider whether it should grant the plaintiff leave to amend. The Ninth Circuit issued its mandate to the district court on April 9, 2021, and the plaintiff has opted for a stay on remand rather than amending the complaint. The two derivative actions pending before the San Diego County Superior Court have been consolidated and have been stayed by agreement of the parties. The Company and the other named defendants dispute, and intend to vigorously defend against, the allegations raised in the consolidated action and the state court derivative actions. In June 2022, the Company finalized a one-time resolution of a contractual claim in an amount of $9.5 million. In view of the inherent difficulty of predicting the outcome of each legal action, particularly since claimants seek substantial or indeterminate damages, it is not possible to reasonably predict or estimate the eventual loss or range of loss, if any, related to each legal action, unless otherwise disclosed above.
