12. Debt

a) Chubb INA senior notes

On August 6, 2025, Chubb INA issued $1.25 billion of 4.90 percent senior notes due August 2035.

These senior unsecured notes are guaranteed on a senior basis by Chubb Limited and they rank equally with all of Chubb INA's other senior obligations. They also contain customary limitations on lien provisions as well as customary events of default provisions which, if breached, could result in the accelerated maturity of such senior debt. These senior notes are redeemable at any time at Chubb INA's option subject to a “make-whole” premium (the present value of the remaining principal and interest discounted at the applicable comparable government bond rate plus 0.15 percent). The notes are also redeemable at par plus accrued and unpaid interest in the event of certain changes in tax law. These notes do not have the benefit of any sinking fund.

Chubb INA's $800 million of 3.15 percent senior notes due March 2025 were paid upon maturity.
