To satisfy this requirement, the Company funded two certificates of deposits (CDs) totaling $172,500 in separate banks. The CDs both have original maturities of three months but are termed restricted cash and classified as a long-term asset as the Company does not anticipate decommissioning the facility until the end of the current lease plus the one remaining three-year lease option period. The end date of the current lease including the one remaining three-year renewal option is April 2019. Interest earned on the CDs is rolled-over at the maturity of each CD and becomes part of the restricted cash balance. Interest earned and added to restricted cash during the fiscal years ended June 30, 2014 and 2013 was $59 and $122, respectively. These funds will be used to settle a portion of the Company's remaining asset retirement obligations (See Note 9).
