During 2013 and 2014 the Company made investments in Lifestreams Technologies Corporation aggregating $576,000 (the original investment was part of the Company's acquisition of the Mirror Worlds Patent Portfolio – see Note I[2] hereof).  Since the Company owned less than 20% of the outstanding equity of Lifestreams and did not have significant influence or control, the Company's investment in Lifestreams was recorded at cost.  A portion of the Company's investment in Lifestreams consisted of secured promissory notes (the "Notes").  The Notes all matured on March 31, 2015. At September 30, 2015, Lifestreams remained in default of the Notes and had not completed any additional material financing. As a result, the Company had an impairment of $386,000 with respect to the investment which had a carrying value at September 30, 2015 of $190,000 compared with a carrying value at December 31, 2014 of $576,000.  The carrying value of $190,000 at September 30, 2015 reflected management's estimate at September 30, 2015 of the fair value of the investment (see Note B hereof).  The impairment of $386,000 was included in general and administrative expenses in the Company's Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2015.  At December 31, 2015, the balance of the carrying value of $190,000 at September 30, 2015 was written-off.
