Fair Value of Long-Term Debt

The Company's outstanding 5.00% Notes had a fair value of $555.7 million and $567.9 million as of March 31, 2018 and December 31, 2017, respectively. The Company's outstanding 5.25% Notes had a fair value of $300.0 million and $310.9 million as of March 31, 2018 and December 31, 2017, respectively. The carrying value of the Company's fixed interest rate borrowings included in real estate related and other long-term debt totaled $85.0 million and $86.8 million as of March 31, 2018 and December 31, 2017, respectively. The fair value of such fixed interest rate borrowings was $91.0 million and $92.9 million as of March 31, 2018 and December 31, 2017, respectively. The fair value estimates are based on Level 2 inputs of the fair value hierarchy available as of March 31, 2018 and December 31, 2017. The Company determined the estimated fair value of its long-term debt using available market information and commonly accepted valuation methodologies. Considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, these estimates are not necessarily indicative of the amounts that the Company, or holders of the instruments, could realize in a current market exchange. The use of different assumptions and/or estimation methodologies could have a material effect on estimated fair values. The carrying value of the Company’s variable rate debt approximates fair value due to the short-term nature of the interest rates.
