Land held for long-term investment represents property located in areas that are not planned to be developed in the near term and thus has not been offered for sale. As of April 30, 2015, the Company held approximately 12,000 acres of land in New Mexico classified as land held for long-term investment.
 
The warehouse facility is leased to a third party at a market rate with a lease term that expires in November 2018. Depreciation associated with the warehouse facility of $145,000 was charged to operations in each of 2015 and 2014.
