During the three month period ended June 30, 2010 management increased the estimated useful life of certain monitoring equipment from three years to five years to more accurately reflect the expected life of the related assets. The effect of the increase in estimated useful life was a decrease in depreciation expense for the nine months ended September 30, 2011 of $124,000, an earnings per share impact of approximately $0.01.
 
During the periods ending September 30, 2011 and September 30, 2010, the Company capitalized software development costs of $163,850 and $159,610, respectively.
