At December 31, 2021, the Company had $754 million of various capital commitments to fund sponsored investment products, including CIPs. These products include private equity funds, real assets funds and opportunistic funds.

The Company intends to make additional capital commitments from time to time to fund additional investment products for, and with, its clients. Contingencies Contingent Payments Related to Business Acquisitions. In connection with certain acquisitions, BlackRock is required to make contingent payments, subject to achieving specified performance targets, which may include revenue related to acquired contracts. The fair value of the remaining aggregate contingent payments at December 31, 2021 totaled $64 million and is included in other liabilities on the consolidated statements of financial condition. Other Contingent Payments. The Company acts as the portfolio manager in a series of derivative transactions and has a maximum potential exposure of $17 million between the Company and a counterparty. See Note 9, Derivatives and Hedging, for further discussion. Legal Proceedings. From time to time, BlackRock receives subpoenas or other requests for information from various US federal and state governmental and regulatory authorities and international governmental and regulatory authorities in connection with industry-wide or other investigations or proceedings. It is BlackRock’s policy to cooperate fully with such matters. The Company, certain of its subsidiaries and employees have been named as defendants in various legal actions, including arbitrations and other litigation arising in connection with BlackRock’s activities. Additionally, BlackRock-advised investment portfolios may be subject to lawsuits, any of which potentially could harm the investment returns of the applicable portfolio or result in the Company being liable to the portfolios for any resulting damages. On April 5, 2017, BlackRock, Inc., BlackRock Institutional Trust Company, N.A. (“BTC”), the BlackRock, Inc. Retirement Committee and various sub-committees, and a BlackRock employee were named as defendants in a purported class action lawsuit brought in the US District Court for the Northern District of California by a former employee on behalf of all participants and beneficiaries in the BlackRock employee 401(k) Plan (the “Plan”) from April 5, 2011 to the present. The lawsuit generally alleges that the defendants breached their duties towards Plan participants in violation of the Employee Retirement Income Security Act of 1974 by, among other things, offering investment options that were overly expensive, underperformed unaffiliated peer funds, focused disproportionately on active versus passive strategies, and were unduly concentrated in investment options managed by BlackRock. On October 18, 2017, the plaintiffs filed an Amended Complaint, which, among other things, added as defendants certain current and former members of the BlackRock Retirement and Investment Committees. The Amended Complaint also included a new purported class claim on behalf of investors in certain CTFs managed by BTC. Specifically, the plaintiffs allege that BTC, as fiduciary to the CTFs, engaged in self-dealing by, most significantly, selecting itself as the securities lending agent on terms that the plaintiffs claim were excessive. The Amended Complaint also alleged that BlackRock took undue risks in its management of securities lending cash reinvestment vehicles during the financial crisis. On August 23, 2018, the court granted permission to the plaintiffs to file a Second Amended Complaint (“SAC”) which added as defendants the BlackRock, Inc. Management Development and Compensation Committee, the Plan’s independent investment consultant and the Plan’s Administrative Committee and its members. On October 22, 2018, BlackRock filed a motion to dismiss the SAC, and on June 3, 2019, the plaintiffs filed a motion seeking to certify both the Plan and the CTF classes. On September 3, 2019, the court granted BlackRock’s motion to dismiss part of the plaintiffs’ claim seeking to recover alleged losses in the securities lending vehicles but denied the motion to dismiss in all other respects. On February 11, 2020, the court denied the plaintiffs’ motion to certify the CTF class and granted their motion to certify the Plan class. On April 27, 2020, the Ninth Circuit denied the plaintiffs’ request to immediately appeal the class certification ruling. On September 24, 2020, the parties cross-moved for summary judgment, both of which were denied on January 12, 2021. On February 5, 2021, the parties reached a settlement in principle for $9.65 million to resolve the remaining claims in the lawsuit, and this settlement was presented to the court for approval on March 23, 2021. There were no class member objections to the settlement following notice, and the court granted final approval of the settlement on November 3, 2021. A final judgment approving the settlement was entered in the district court on November 8, 2021. The case is now closed. Management, after consultation with legal counsel, currently does not anticipate that the aggregate liability arising out of regulatory matters or lawsuits will have a material effect on BlackRock’s results of operations, financial position, or cash flows. However, there is no assurance as to whether any such pending or threatened matters will have a material effect on BlackRock’s results of operations, financial position or cash flows in any future reporting period. Due to uncertainties surrounding the outcome of these matters, management cannot reasonably estimate the possible loss or range of loss that may arise from these matters. Indemnifications. In the ordinary course of business or in connection with certain acquisition agreements, BlackRock enters into contracts pursuant to which it may agree to indemnify third parties in certain circumstances. The terms of these indemnities vary from contract to contract and the amount of indemnification liability, if any, cannot be determined or the likelihood of any liability is considered remote. Consequently, no liability has been recorded on the consolidated statements of financial condition. In connection with securities lending transactions, BlackRock has agreed to indemnify certain securities lending clients against potential loss resulting from a borrower’s failure to fulfill its obligations under the securities lending agreement should the value of the collateral pledged by the borrower at the time of default be insufficient to cover the borrower’s obligation under the securities lending agreement. The amount of securities on loan as of December 31, 2021 and subject to this type of indemnification was $286 billion. In the Company’s capacity as lending agent, cash and securities totaling $304 billion were held as collateral for indemnified securities on loan at December 31, 2021. The fair value of these indemnifications was not material at December 31, 2021.

Management, after consultation with legal counsel, currently does not anticipate that the aggregate liability arising out of regulatory matters or lawsuits will have a material effect on BlackRock’s results of operations, financial position, or cash flows. However, there is no assurance as to whether any such pending or threatened matters will have a material effect on BlackRock’s results of operations, financial position or cash flows in any future reporting period. Due to uncertainties surrounding the outcome of these matters, management cannot reasonably estimate the possible loss or range of loss that may arise from these matters.

Indemnifications. In the ordinary course of business or in connection with certain acquisition agreements, BlackRock enters into contracts pursuant to which it may agree to indemnify third parties in certain circumstances. The terms of these indemnities vary from contract to contract and the amount of indemnification liability, if any, cannot be determined or the likelihood of any liability is considered remote. Consequently, no liability has been recorded on the consolidated statements of financial condition.

In connection with securities lending transactions, BlackRock has agreed to indemnify certain securities lending clients against potential loss resulting from a borrower’s failure to fulfill its obligations under the securities lending agreement should the value of the collateral pledged by the borrower at the time of default be insufficient to cover the borrower’s obligation under the securities lending agreement. The amount of securities on loan as of December 31, 2021 and subject to this type of indemnification was $286 billion. In the Company’s capacity as lending agent, cash and securities totaling $304 billion were held as collateral for indemnified securities on loan at December 31, 2021. The fair value of these indemnifications was not material at December 31, 2021.
