(1) Fair value is categorized as level 2 within the fair value hierarchy since the notes trade infrequently. Fair value is based on quoted market prices.

(2) Fair value approximates the carrying amount as the variable interest rates reprice frequently at observable current market rates. As such, fair value is categorized as level 2 within the fair value hierarchy.

(3) Fair value for certain debt is estimated based on the discounted value of future cash flows using observable current market interest rates offered for debt of similar credit risk and maturity. As such, fair value is categorized as level 2 within the fair value hierarchy.
