Based on the length of time our technology is expected to be used and an evaluation of the lives of similar technology in the industry, effective January 1, 2014, we increased the estimated useful lives of certain technologies acquired in 2010 and 2012 from 7 years to 10 years, which decreased loss from operations by $0.1 million and net loss by $0.1 million, or $0.01 per basic and diluted share, for the three months ended June 30, 2014.
