FAIR VALUE OF FINANCIAL INSTRUMENTS
FAIR VALUE OF FINANCIAL INSTRUMENTS
Except as disclosed below, the carrying amount of our financial instruments approximates their fair value. The fair value of our mortgages payable, notes payable and senior notes and debentures is sensitive to fluctuations in interest rates. Quoted market prices (Level 1) were used to estimate the fair value of our marketable senior notes and debentures and discounted cash flow analysis (Level 2) is generally used to estimate the fair value of our mortgages and notes payable. Considerable judgment is necessary to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. A summary of the carrying amount and fair value of our mortgages payable, notes payable and senior notes and debentures is as follows:

As of June 30, 2018, we have two interest rate swap agreements with a notional amount of $275.0 million that are measured at fair value on a recurring basis. The interest rate swap agreements fix the variable portion of our $275.0 million term loan at 1.72% through November 1, 2018. We assess effectiveness of our cash flow hedges both at inception and on an ongoing basis. The effective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recorded in accumulated other comprehensive loss and is subsequently reclassified into interest expense as interest is incurred on the related variable rate debt. Within the next 12 months, we expect to reclassify an estimated $0.4 million as a decrease to interest expense. Our cash flow hedges become ineffective if critical terms of the hedging instrument and the debt instrument do not perfectly match such as notional amounts, settlement dates, reset dates, calculation period and LIBOR rate. In addition, we evaluate the default risk of the counterparty by monitoring the credit-worthiness of the counterparty. When ineffectiveness exists, the ineffective portion of changes in fair value of the interest rate swaps associated with our cash flow hedges is recognized in earnings in the period affected. Hedge ineffectiveness has not impacted earnings as of June 30, 2018, and we do not anticipate it will have a significant effect in the future.
The fair values of the interest rate swap agreements are based on the estimated amounts we would receive or pay to terminate the contracts at the reporting date and are determined using interest rate pricing models and interest rate related observable inputs. The fair value of our swaps at June 30, 2018 was an asset of $0.4 million and is included in "prepaid expenses and other assets" on our consolidated balance sheets. For the three and six months ended June 30, 2018, the change in valuation on our interest rate swaps resulted in a $0.1 million decrease in our derivative asset and a $0.4 million increase in our derivative asset, respectively, (including $0.2 million and $0.1 million, respectively, reclassified from other comprehensive income as a decrease to interest expense). The change in valuation on our interest rate swaps is included in "accumulated other comprehensive income."
