6.	Deferred License Fees

BioTime amortizes deferred license fees over the estimated useful lives of the licensed technologies or licensed research products. BioTime is applying a 10 year estimated useful life to the technologies and products that it is currently licensing. The estimation of the useful life of any technology or product involves a significant degree of inherent uncertainty, since the outcome of research and development or the commercial life a new product cannot be known with certainty at the time that the right to use the technology or product is acquired. BioTime periodically reviews its amortization schedules for impairments that might occur earlier than the original expected useful lives.

As of June 30, 2015, future amortization of deferred license fees described above was as follows (in thousands):
