In January 2012, geothermal water rights located on 2,398 acres in San Emidio in the State of Nevada were segregated from the San Emidio plant operations to be utilized for a future project. The net value of the transferred rights was $3,010,507 ($3,440,580 cost, less $430,073 amortization). Amortization of these costs is no longer being charged to operations.

Estimated aggregate amortization expense for the next five fiscal years is as follows:

    Projected

2014   160,841  
2015   160,841  
2016   160,841  
2017   160,841  
       
  $ 804,205  

Amortization expense charged to operations for the three months ended June 30, 2012 and 2011 amounted to $40,210 and $68,881, respectively.
