I don't have a cash concern and here is why

Net loss of 12 M$ doesn't equal annual burn-rate

You have to substract the non-cash based compensation (i.e. stock options issued) of 4.8 M$

Therefore, a more accurate number would be 12 - 4.8 = 7.2M$

With 14.5 M$ in the bank as of Dec 31 2015, I agree with their statement below :

Based on current plans and cash utilization, we believe we have sufficient liquidity to support our operations and technological programs beyond the end of 2016, which include further development of the POET semiconductor process and increasing the POET intellectual property portfolio to enable us to exploit POET, through licenses and collaborative arrangements.
