Derivative and Other Fair Value Instruments |
10. | Derivative and Other Fair Value Instruments
The valuation of financial instruments requires the Company to make estimates and judgments that affect the fair value of the instruments. The Company, where possible, bases the fair values of its financial instruments, including its derivative instruments, on listed market prices and third-party quotes. Where these are not available, the Company bases its estimates on current instruments with similar terms and maturities or on other factors relevant to the financial instruments. In the normal course of business, the Company is exposed to the effect of interest rate changes. The Company may seek to manage these risks by following established risk management policies and procedures including the use of derivatives to hedge interest rate risk on debt instruments. The Company may also use derivatives to manage commodity prices in the daily operations of the business. A three-level valuation hierarchy exists for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows:
| • | Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
| • | Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.
| • | Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement.
The Company’s derivative positions are valued using models developed by the respective counterparty as well as models applied internally by the Company that use as their inputs readily observable market parameters (such as forward yield curves and credit default swap data). The following table summarizes the inputs to the valuations for each type of fair value measurement:
Fair Value Measurement Type |  | Valuation Inputs
Employee holdings (other than Common Shares) within the supplemental executive retirement plan (the “SERP”) |  | Quoted market prices for identical assets. These holdings are included in other assets and other liabilities on the consolidated balance sheets.
Redeemable Noncontrolling Interests – Operating Partnership/Redeemable Limited Partners |  | Quoted market price of Common Shares.
Mortgage notes payable and private unsecured debt (including its commercial paper and line of credit, if applicable) |  | Indicative rates provided by lenders of similar loans.
Public unsecured notes |  | Quoted market prices for each underlying issuance.
The fair values of the Company’s financial instruments (other than mortgage notes payable, unsecured notes, commercial paper, line of credit and derivative instruments), including cash and cash equivalents and other financial instruments, approximate their carrying or contract value. The following table provides a summary of the carrying and fair values for the Company’s mortgage notes payable and unsecured debt (including its commercial paper and line of credit, if applicable) at December 31, 2020 and 2019, respectively (amounts in thousands):

As of December 31, 2020 and 2019, there were approximately $43.7 million and $77.6 million in deferred losses, net, included in accumulated other comprehensive income (loss), respectively, related to derivative instruments, of which an estimated $10.2 million may be recognized as additional interest expense during the twelve months ending December 31, 2021. In April 2020, the Company paid approximately $1.2 million to settle two forward starting swaps in conjunction with the issuance of $495.0 million of ten-year secured conventional mortgage notes. The entire $1.2 million was initially deferred as a component of accumulated other comprehensive income (loss) and will be recognized as an increase to interest expense over the first five years of the mortgage notes. In July 2019, six fair value interest rate swaps matured in conjunction with the maturity of $450.0 million of 2.375% unsecured notes. In June 2019, the Company paid approximately $41.8 million to settle ten forward starting swaps in conjunction with the issuance of $600.0 million of ten-year unsecured public notes. The accrued interest of approximately $0.2 million was recorded as an increase to interest expense. The remaining $41.6 million will be deferred as a component of accumulated other comprehensive income (loss) and will be recognized as an increase to interest expense over the first nine years and eleven months of the notes. In November 2018, the Company received approximately $16.4 million to settle six forward starting swaps in conjunction with the issuance of $400.0 million of ten-year unsecured public notes. The accrued interest of approximately $120,000 was recorded as an increase to interest expense. The remaining $16.5 million will be deferred as a component of accumulated other comprehensive income (loss) and will be recognized as a decrease to interest expense over the first nine years and nine months of the notes. In February 2018, the Company received approximately $1.6 million to settle two forward starting swaps in conjunction with the issuance of $500.0 million of ten-year unsecured public notes. The entire $1.6 million was initially deferred as a component of accumulated other comprehensive income (loss) and will be recognized as a decrease to interest expense over the ten-year term of the notes.
