Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial InstrumentsDuring 2019, we entered into $150.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at 1.87% with respect to a planned issuance of debt securities by the Operating Partnership. Upon the subsequent issuance of the $400.0 million aggregate principal amount of 3.050% notes due February 2030 during 2019, we terminated the forward-starting swaps and paid cash upon settlement. The unrealized loss of $6.6 million in accumulated other comprehensive income/(loss) will be reclassified to interest expense as interest payments are made on the debt.

During 2018, we entered into an aggregate of $225.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at a weighted average of 2.86% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $350.0 million aggregate principal amount of 4.20% notes due April 2029 during 2019, we terminated the forward-starting swaps and paid cash upon settlement. The unrealized loss of $5.1 million in accumulated other comprehensive income/(loss) will be reclassified to interest expense as interest payments are made on the debt.

We previously entered into $150.0 million notional amount of forward-starting swaps that effectively locked the underlying 10-year treasury rate at 2.44% with respect to a planned issuance of debt securities by the Operating Partnership. Upon issuance of the $350.0 million aggregate principal amount of 4.125% notes due March 2028 during 2018, we terminated the forward-starting swaps and received cash upon settlement. The unrealized gain of $7.0 million in accumulated other comprehensive income/(loss) will be reclassified to interest expense as interest payments are made on the debt and a gain of $0.2 million of hedge ineffectiveness was recognized in interest expense.

We previously entered into floating-to-fixed interest rate swaps through January 2022 with respect to an aggregate of $50.0 million LIBOR-based borrowings. These swaps effectively fix the underlying one-month LIBOR rate at a weighted average rate of 1.693%.

We also had floating-to-fixed interest rate swaps with respect to an aggregate of $225.0 million LIBOR-based borrowings. These swaps effectively fixed the underlying one-month LIBOR rate at a weighted average rate of 1.678%. During 2019, these interest rate swaps expired.

The counterparties under our swaps are major financial institutions. The swap agreements contain a provision whereby if we default on certain of our indebtedness and which default results in repayment of such indebtedness being, or becoming capable of being, accelerated by the lender, then we could also be declared in default on our swaps.

Our interest rate swaps have been designated as and are being accounted for as cash flow hedges with changes in fair value recorded in other comprehensive income/(loss) each reporting period. We have no collateral requirements related to our interest rate swaps.

Amounts reported in accumulated other comprehensive income/(loss) related to derivatives will be reclassified to interest expense as interest payments are made on our debt. During 2021, we estimate that $0.5 million will be reclassified as a net increase to interest expense.
