        <footnote id="F1">Each $1,000 original principal amount of 2.125% exchangeable senior debentures due 2048 (the &quot;Debentures&quot;) was exchangeable for 124.6922 shares of the issuer's common stock, par value $0.001 per share (the &quot;Common Stock&quot;), settled only in cash based on the value of the shares of Common Stock.</footnote>
        <footnote id="F2">Each Debenture was exchangeable at the option of the holder and holders of the Debentures were also able to put them to the reporting person, in each case through the close of business on April 5, 2023, for settlement in cash on April 7, 2023. In addition, all outstanding Debentures were irrevocably called for redemption by the reporting person with a redemption date of April 7, 2023.</footnote>
        <footnote id="F3">On April 5, 2023, the reporting person accepted for repurchase in cash $255,091,000 aggregate original principal amount of Debentures and on April 7, 2023, the reporting person redeemed for cash $28,961,000 aggregate original principal amount of Debentures (the &quot;Redemption&quot;). In either case, holders of the Debentures received payment of $968.57 for each $1,000 original principal amount of the Debentures, inclusive of accrued and unpaid interest. As a result of the Redemption, no Debentures remain outstanding.</footnote>
