Derivatives and Hedging Activities
Derivatives and Hedging Activities	8. Derivatives and Hedging Activities On April 19, 2018, we entered into a $75 million forward starting five-year interest rate swap agreement, effective May 5, 2018, to protect against adverse fluctuation in interest rates. The swap reduces our exposure to variability in cash flows relating to interest payments on $75 million of one-month LIBOR variable rate debt and effectively fixes the interest rate at approximately 4.12% per annum. On April 21, 2017, we terminated $50 million of our previously existing $100 million five-year interest rate swap agreement that reduces our exposure to variability in cash flows relating to interest payments based on one-month LIBOR variable rate debt, resulting in a remaining $50 million interest rate swap effective through January 31, 2019, at approximately 2.88% and 2.98% per annum as of September 30, 2018, and December 31, 2017. On April 9, 2015, we entered into a $75 million forward starting five-year interest rate swap agreement, effective May 5, 2015, to protect against adverse fluctuation in interest rates. The swap reduces our exposure to variability in cash flows relating to interest payments on $75 million of one-month LIBOR variable rate debt and effectively fixes the interest rate at approximately 2.83% and 2.93% per annum as of September 30, 2018, and December 31, 2017. All interest rate swap agreements were designated for hedge accounting. Risk Management Objective of Using Derivatives We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of our debt funding and the use of derivative financial instruments. Specifically, we enter into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known or uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are used to manage differences in the amount, timing, and duration of our known or expected cash receipts and our known or expected cash payments principally related to our investments and borrowings. Cash Flow Hedges of Interest Rate Risk Our objectives in using interest rate derivatives are to reduce variability in interest expense and to manage our exposure to adverse interest rate movements. To accomplish this objective, we primarily use interest rate swaps as part of our interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income or loss on the condensed consolidated balance sheets and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The amounts recorded in other comprehensive income or loss related to the unrealized gain or loss on derivative contracts were gains of $0.5 million and less than $0.1 million for the three months ended September 30, 2018, and 2017, respectively, and were gains of $1.4 million and less than $0.1 million for the nine months ended September 30, 2018, and 2017, respectively. The amounts reclassified from other comprehensive income (loss) to interest expense on the condensed consolidated statements of operations were ($0.1) million and $0.1 million for the three months ended September 30, 2018, and 2017, respectively, and were ($0.1) million and $0.6 million for the nine months ended September 30, 2018, and 2017, respectively. Total interest expense presented in the condensed consolidated statements of operations in which the effects of cash flow hedges are recorded was $9.4 million and $6.4 million for the three months ended September 30, 2018, and 2017, respectively, and $26.1 million and $17.5 million for the nine months ended September 30, 2018, and 2017, respectively. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the subsequent twelve months, beginning October 1, 2018, we estimate that $0.9 million will be reclassified as an increase to interest expense. Derivatives are recorded at fair value in our condensed consolidated balance sheets in other assets or unearned revenue, prepaid rent and other liabilities, as applicable. We do not net our derivative position by counterparty for purposes of balance sheet presentation and disclosure. We had $2.3 million and $1.1 million in derivative assets recognized in other assets in our condensed consolidated balance sheets as of September 30, 2018, and December 31, 2017, respectively.

Cash Flow Hedges of Interest Rate Risk

Our objectives in using interest rate derivatives are to reduce variability in interest expense and to manage our exposure to adverse interest rate movements.

Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income or loss on the condensed consolidated balance sheets and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The amounts recorded in other comprehensive income or loss related to the unrealized gain or loss on derivative contracts were gains of $0.5 million and less than $0.1 million for the three months ended September 30, 2018, and 2017, respectively, and were gains of $1.4 million and less than $0.1 million for the nine months ended September 30, 2018, and 2017, respectively.

Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the subsequent twelve months, beginning October 1, 2018, we estimate that $0.9 million will be reclassified as an increase to interest expense.
