⁽¹⁾ We calculate the fair value of asset retirement obligations by discounting the estimated amount using the current Treasury bill rate adjusted for our credit non-performance. We include current asset retirement obligations of $1.3 million and $1.4 million in “Other current liabilities” in the consolidated balance sheets for September 30, 2014 and December 31, 2013, respectively. We include long-term asset retirement obligations of $2.5 million and $1.0 million in “Other long-term liabilities” in the consolidated balance sheets for September 30, 2014 and December 31, 2013, respectively.

⁽²⁾ Included in “Cash and cash equivalents” in the consolidated balance sheet as of December 31, 2013. Unrealized gains and losses on money market funds were nominal due to the short-term nature of the investments.

- Definition

Tabular disclosure of the fair value measurement of liabilities using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes attributable to the following: (1) total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings (or changes in net assets), and gains or losses recognized in other comprehensive income (loss) and a description of where those gains or losses included in earnings (or changes in net assets) are reported in the statement of income (or activities); (2) purchases, sales, issues, and settlements (each type disclosed separately); and (3) transfers in and transfers out of Level 3 (for example, transfers due to changes in the observability of significant inputs) by class of liability.
