At December 31, 2015, cash and cash equivalents totaled $846,000, compared to $775,000 at December 31, 2014.

The cash used in operations for the year ended December 31, 2015 was primarily attributable to the net loss of $3,917,000 and an $18,000 gain on derivative liability.

For the year ended December 31, 2015, the cash used in investing activities of $48,000 resulted from the acquisition of leasehold improvements associated with the sub-lease of approximately 3,000 square feet of unutilized office space.
