Fair Value of Financial Instruments [Abstract] |
Fair Value of Financial Instruments | 4. Fair Value of Financial Instruments The carrying value of our cash and cash equivalents, accounts receivable and accounts payable approximate fair value because of their short-term nature. Our investments consist of U.S. treasury notes with maturities of up to one year. Fair value of investments is measured using Level 1 inputs. We designate the appropriate classification of our investments at the time of purchase based upon the intended holding period. As of September 30, 2018, we transferred the classification of our investments from available-for-sale (“AFS”) to held-to-maturity (“HTM”) due to our ability and intent to hold these securities to maturity. The transfer from AFS to HTM was recorded at the fair value of the AFS securities at the time of transfer. The unrealized holding loss of $303, net of tax, at the date of transfer was retained in other comprehensive income (loss) on the consolidated statement of comprehensive income. Such amounts will be amortized to interest and other income on the consolidated statement of income over the remaining life of the securities. The amortization of this unrealized holding loss will be offset by the discount created as a result of this reclassification, which will also be amortized over the remaining life of the securities to interest and other income on the consolidated statement of income. HTM securities are carried at amortized cost, which approximated fair value as of December 31, 2018. We recognize impairment charges when management believes the decline in the fair value of the investment is other-than-temporary. No impairment charges were recognized on our investments for the twelve months ended December 31, 2018. The fair value of our investments as of December 31, 2017, which were then classified as AFS, was $32 4,382, which included an unrealized loss of $493. Realized gains and losses on AFS securities are recorded in interest and other income on the consolidated statement of income. We had no realized gains or losses for the years ended December 31, 2018 and 2017, and $547 of realized gains on AFS securities for the year ended December 31, 2016. We have elected to fund certain deferred compensation obligations through a rabbi trust, the assets of which are designated as trading securities, as described further in Note 10. “Employee Benefit Plans.” ﻿ Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis ﻿ Assets recognized or disclosed at fair value on the consolidated financial statements on a nonrecurring basis include items such as leasehold improvements, property and equipment, goodwill, and other intangible assets. These assets are measured at fair value if determined to be impaired. ﻿ Other than as disclosed in Note 5. “Corporate Restructuring Costs” and Note 6. “Restaurant Closure Costs and Impairment of Long-Lived Assets” as of December 31, 2018 and 2017, we had no non-financial assets or liabilities that were measured using Level 3 inputs. ﻿
