      <additionalInformation>This Amendment is being filed solely for the purpose of removing from the Form 13F Information Table certain shares of Class A Common Stock of Aurora Innovation, Inc. ("Class A Common") inadvertently included in the Form 13F filed by the Reporting Person for the quarter ended December 31, 2024. As of December 31, 2024, the Reporting Person or its affiliates exercised investment discretion over 11,746,572 shares of Class B Common Stock of Aurora Innovation, Inc. ("Class B Common"). While shares of Class A Common are Section 13(f) securities as defined in Rule 13f-1(c) under the Securities and Exchange Act of 1934, shares of Class B Common are not Section 13(f) securities and thus not reportable. For the avoidance of doubt, this Amendment is to correct a clerical error only, and does not reflect the disposition by the Reporting Person of any shares of Class A Common or Class B Common.</additionalInformation>
