[1] Diluted net loss per share does not reflect any potential common stock relating to stock options or restricted stock units due to net losses incurred for the nine months ended March 31, 2017 and three and nine months ended March 31, 2016. The assumed issuance of any additional shares would be anti-dilutive.

[2] These weighted-shares relate to anti-dilutive stock options and restricted stock units as calculated using the treasury stock method and could be dilutive in the future.
