FAIR VALUE OF FINANCIAL INSTRUMENTS

Our financial assets and liabilities measured at fair value (based on the hierarchy of the three levels of inputs described in Note 1 to the consolidated financial statements contained in our most recent Annual Report on Form 10-K) on a recurring basis have included marketable securities, derivative financial instruments and contingent consideration arrangements. Derivative financial instruments include our interest rate swap agreements. Contingent consideration arrangements relate to certain provisions of recent real estate purchase agreements involving business combinations.

Derivative financial instruments. Derivative financial instruments are valued in the market using discounted cash flow techniques. These techniques incorporate Level 1 and Level 2 inputs. The market inputs are utilized in the discounted cash flow calculation considering the instrument’s term, notional amount, discount rate and credit risk. Significant inputs to the derivative valuation model for interest rate swaps are observable in active markets and are classified as Level 2 in the hierarchy.

Contingent consideration. Contingent consideration arrangements are classified as Level 3 and are valued using unobservable inputs about the nature of the contingent arrangement and the counter-party to the arrangement, as well as our assumptions about the probability of full settlement of the contingency.

Fixed rate debt. Fixed rate debt is classified as Level 2 and its value is based on quoted prices for similar instruments or calculated utilizing model derived valuations in which significant inputs are observable in active markets.

Mortgage and other notes receivable. The fair value of mortgage and other notes receivable is based on credit risk and discount rates that are not observable in the marketplace and therefore represents a Level 3 measurement.

Carrying amounts of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to their short-term nature. The fair value of our borrowings under our revolving credit facility and other variable rate debt are reasonably estimated at their notional amounts at June 30, 2018 and December 31, 2017, due to the predominance of floating interest rates, which generally reflect market conditions.
