The fair value of our mortgage debt is a Level 2 measurement under the fair value hierarchy (see Note 2). We estimate the fair value of our mortgage debt by discounting the future cash flows of each instrument at estimated market rates. The carrying value of our other financial instruments approximate fair value due to the short-term nature of these financial instruments.
