Derivatives

Our objectives in using derivatives are to add stability to interest expense and to manage our cash flow volatility and exposure to interest rate movements. To accomplish this objective, we primarily use interest rate protection agreements as part of our interest rate risk management strategy. Interest rate protection agreements designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

Fair Value Hedges

In connection with the originations of the Unsecured Term Loans (see Note 4), we entered into interest rate protection agreements to manage our exposure to changes in the one month LIBOR rate. The four interest rate protection agreements, which fix the variable rate of the 2014 Unsecured Term Loan, have an aggregate notional value of $200,000, mature on January 29, 2021 and fix the LIBOR rate at a weighted average rate of 2.29% (the "2014 Swaps"). The six interest rate protection agreements, which fix the variable rate of the 2015 Unsecured Term Loan, have an aggregate notional value of $260,000, mature on September 12, 2022 and fix the LIBOR rate at a weighted average rate of 1.79% (the "2015 Swaps"). We designated the 2014 Swaps and 2015 Swaps as cash flow hedges.

Our agreements with our derivative counterparties contain provisions where if we default on any of our indebtedness, then we could also be declared in default on our derivative obligations subject to certain thresholds. As of June 30, 2018, we had not posted any collateral related to these agreements and were not in breach of any of the provisions of these agreements. If we had breached these agreements, we could have been required to settle our obligations under the agreements at their termination value.

The following table sets forth our financial assets related to the 2015 Swaps and the 2014 Swaps which are included in prepaid expenses and other assets on the consolidated balance sheets and which are accounted for at fair value on a recurring basis as of June 30, 2018:



			Fair Value Measurements:
Description	Fair Value		Quoted Prices in Active Markets for Identical Assets (Level 1)	Significant Other Observable Inputs (Level 2)		Unobservable Inputs (Level 3)
Derivatives designated as a hedging instrument:
Assets:
2014 Swaps	$	1,862	—	$	1,862	—
2015 Swaps	$	9,774	—	$	9,774	—

There was no ineffectiveness recorded on the 2014 Swaps and 2015 Swaps during the six months ended June 30, 2018. See Note 7 for more information regarding our derivatives.

The estimated fair value of the 2014 Swaps and the 2015 Swaps was determined using the market standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments are incorporated in the fair value to account for potential non-performance risk, including our own non-performance risk and the respective counterparty's non-performance risk. We determined that the significant inputs used to value the 2014 Swaps and the 2015 Swaps fell within Level 2 of the fair value hierarchy.
