Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Financial Instruments - Derivatives and Hedging | Financial Instruments - Derivatives and Hedging The Company’s use of derivative instruments is limited to the utilization of interest rate agreements or other instruments to manage interest rate risk exposures and not for speculative purposes. In certain situations, the Company may enter into derivative financial instruments such as interest rate swap and interest rate cap agreements that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s objective in using interest rate derivatives is to add stability to interest expense and to manage its exposure to interest rate movements. Cash Flow Hedges of Interest Rate Risk Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without changing the underlying notional amount. During the three and nine months ended September 30, 2017, the Company did not enter into any new interest rate swap agreements. During the year ended December 31, 2016, the Company entered into nine forward starting interest rate swap agreements (the “Swaps”) with an effective date of November 1, 2016 and an aggregate notional value of $1.4 billion to partially hedge the variable cash flows associated with variable LIBOR based interest rate debt. Detail of the Company’s interest rate derivatives designated as cash flow hedges outstanding as of September 30, 2017 and December 31, 2016 is as follows:
|  | Number of Instruments |  | Notional Amount
|  | September 30, 2017 |  | December 31, 2016 |  | September 30, 2017 |  | December 31, 2016
Interest Rate Swaps |  | 9 |  | 9 |  | $ | 1,400,000 |  |  | $ | 1,400,000 |
The Company has elected to present its interest rate derivatives on its unaudited Condensed Consolidated Balance Sheets on a gross basis as interest rate swap assets and interest rate swap liabilities. Detail on the Company’s fair value of interest rate derivatives on a gross and net basis as of September 30, 2017 and December 31, 2016, respectively, is as follows:
|  | Fair Value of Derivative Instruments
Interest rate swaps classified as: |  | September 30, 2017 |  | December 31, 2016
Gross derivative assets |  | $ | 20,171 |  |  | $ | 21,605 |
Gross derivative liabilities |  | — |  |  | — |
Net derivative assets |  | $ | 20,171 |  |  | $ | 21,605 |
The gross derivative assets are included in Other assets and the gross derivative liabilities are included in Accounts payable, accrued expenses and other liabilities on the Company's unaudited Condensed Consolidated Balance Sheets. All of the Company’s outstanding interest rate swap agreements for the periods presented were designated as cash flow hedges of interest rate risk. The fair value of the Company's interest rate derivatives is determined using market standard valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. These inputs are classified as Level 2 of the fair value hierarchy. The effective portion of changes in the fair value of derivatives designated as, and that qualify as, cash flow hedges is recognized in other comprehensive income (“OCI”) and is reclassified into earnings as interest expense in the period that the hedged forecasted transaction affects earnings. The effective portion of the Company's interest rate swaps that was recognized in the Company’s unaudited Condensed Consolidated Statement of Comprehensive Income for the three and nine months ended September 30, 2017 and 2016 is as follows:
Derivatives in Cash Flow Hedging Relationships (Interest Rate Swaps) |  | Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2017 |  | 2016 |  | 2017 |  | 2016
Change in unrealized gain (loss) on interest rate swaps |  | $ | 132 |  |  | $ | 79 |  |  | $ | (532 | ) |  | $ | (1,704 | )
Amortization of interest rate swaps to interest expense |  | (1,094 | ) |  | 1,242 |  |  | (902 | ) |  | 4,117 |
Change in unrealized gain (loss) on interest rate swaps, net |  | $ | (962 | ) |  | $ | 1,321 |  |  | $ | (1,434 | ) |  | $ | 2,413 |
The Company estimates that $7.0 million will be reclassified from accumulated other comprehensive income as a decrease to interest expense over the next twelve months. No gain or loss was recognized related to hedge ineffectiveness or to amounts excluded from effectiveness testing on the Company’s cash flow hedges during the three and nine months ended September 30, 2017 and 2016. Non-Designated (Mark-to Market) Hedges of Interest Rate Risk The Company does not use derivatives for trading or speculative purposes. As of September 30, 2017 and December 31, 2016, the Company did not have any non-designated hedges. Credit-risk-related Contingent Features The Company has agreements with its derivative counterparties that contain a provision whereby if the Company defaults on certain of its indebtedness and the indebtedness has been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. If the Company were to breach any of the contractual provisions of the derivative contracts, it would be required to settle its obligations under the agreements at their termination value including accrued interest.
