[1] We estimated the fair value of the YUM and Subsidiary Senior Unsecured Notes, Term Loan A Facility, and Term Loan B Facility using market quotes and calculations based on market rates.

[2] We estimated the fair value of the Securitization Notes by obtaining broker quotes from two separate brokerage firms that are knowledgeable about the Company’s Securitization Notes and, at times, trade these notes. The markets in which the Securitization Notes trade are not considered active markets.
