In addition to customary event of default provisions, the indenture governing the senior notes, including the applicable
supplemental indentures with respect to the 2030, 2034, and 2036 senior notes, limits the Company’s ability to consolidate,
merge, or sell all or substantially all of its assets, and requires the Company to make an offer to repurchase the applicable senior
notes at 101% of the principal amount, plus any accrued and unpaid interest thereon to, but not including, the date of
repurchase, upon certain change of control triggering events.  The senior notes may be redeemed, in whole or in part, at a make-
whole redemption price (plus accrued and unpaid interest), at any time prior to March 15, 2030, in the case of the 2030 senior
notes, at any time prior to May 20, 2034, in the case of the 2034 senior notes, and at any time prior to November 15, 2035, in
the case of the 2036 senior notes.  The make-whole redemption price, in each case, is equal to the greater of 100% of the
principal amount of the notes to be redeemed and the remaining principal and interest payments on the notes being redeemed
(excluding accrued but unpaid interest to, but not including, the redemption date) discounted to their present value as of the
redemption date on a semi-annual basis at the applicable Treasury rate plus 0.40%, in the case of the 2030 senior notes, and
plus 0.25%, in the case of the 2034 and 2036 senior notes.  In addition, the 2030, 2034, and 2036 senior notes may be
redeemed, in whole or in part, at any time, on or after March 15, 2030, May 20, 2034, and November 15, 2035, respectively, at
a redemption price equal to 100% of the principal amount of the notes to be redeemed plus accrued and unpaid interest thereon
to, but not including, the redemption date.

As of June 30, 2026, each of the 2059 and the 2060 junior subordinated notes could be redeemed at any time, in whole or
in part.  The other junior subordinated notes may be redeemed at any time, in whole or in part, on or after September 30, 2026,
in the case of the 2061 junior subordinated notes, and on or after March 30, 2029, in the case of the 2064 junior subordinated
notes.  In each case, the junior subordinated notes may be redeemed at 100% of the principal amount of the notes being
redeemed, plus any accrued and unpaid interest thereon.  Prior to the applicable redemption date, at the Company’s option, the
applicable junior subordinated notes may also be redeemed, in whole but not in part, at 100% of the principal amount, plus any
accrued and unpaid interest, if certain changes in tax laws, regulations, or interpretations occur; or at 102% of the principal
amount, plus any accrued and unpaid interest, if a rating agency makes certain changes relating to the equity credit criteria for
securities with features similar to the applicable notes.
The Company may, at its option, and subject to certain conditions and restrictions, defer interest payments subject to the
terms of the junior subordinated notes.
Junior Convertible Securities
On December 8, 2025, the Company delivered notice that it had elected to redeem all of its outstanding 5.15% junior
convertible trust preferred securities (the “junior convertible securities”) on December 29, 2025 (the “Redemption Date”), and
announced its intention to settle any and all conversion obligations in cash.  Substantially all holders of the junior convertible
securities delivered requests to convert their securities prior to the Redemption Date.  On December 15, 2025 (the “Election
Date”), the Company made an irrevocable election to settle its conversion obligations in cash by reference to the daily volume
weighted average price of the Company’s common stock during each applicable ten trading day conversion reference period. 
These conversions resulted in a settlement value in excess of the associated carrying value (the “conversion premium”).  As of
December 31, 2025, the conversion premium of $155.5 million was recorded within Other liabilities, with a corresponding
reduction to Additional paid-in capital.  In addition, the conversion resulted in a reduction to Deferred tax liability (net) on the
Consolidated Balance Sheets of $38.9 million, with a corresponding increase to Additional paid-in capital.  The Company’s
election to settle each applicable conversion premium in cash using a ten-day reference period was accounted for as a forward
sale contract, which resulted in a $9.2 million expense recorded in Other expenses (net), in the fourth quarter of 2025. 
On the Redemption Date, the Company redeemed $1.1 million of junior convertible securities which were not converted,
reflecting the principal amount of the redeemed securities, plus accrued and unpaid interest, up to, but not including, the
Redemption Date.
In January 2026, the Company settled each of its applicable conversion obligations in cash for an aggregate amount of
$514.6 million which resulted in an incremental expense related to the forward sale contract of $9.3 million.  The junior
convertible securities were considered contingent payment debt instruments under federal income tax regulations, which
required the Company to deduct interest in an amount greater than its reported interest expense (“excess interest expense
deductions”). As a result of the settlement of these securities, the Company incurred a current cash tax liability of
approximately $56 million, reflective of the recapture of excess interest expense deductions.
Prior to their redemption by the Company or requests for conversion by the holders, as applicable and described above, the
junior convertible securities bore interest at a rate of 5.15% per annum, which interest payments were payable quarterly in cash
For the three months ended June 30, 2025, the Company recorded interest expense of $4.5 million, in connection with the junior
convertible securities, including contractual interest expense and amortization of debt issuance costs of $4.4 million and $0.1
million, respectively.  For the six months ended June 30, 2025, the Company recorded interest expense of $8.9 million, in
connection with the junior convertible securities, including contractual interest expense and amortization of debt issuance costs
of $8.8 million and $0.1 million, respectively.  For the three and six months ended June 30, 2025, the effective interest rate was
5.21%.
