NET INCOME (LOSS) PER SHARE
NET INCOME (LOSS) PER SHARE
Equity Instruments Outstanding
We have stock options and restricted stock units granted under various stock incentive plans that, upon exercise and vesting, respectively, would increase shares outstanding. We have 4.50% convertible subordinated notes which are convertible at the option of the holders at any time prior to maturity into shares of Quantum common stock at a conversion price of $1.65 per share. We also have 3.50% convertible subordinated notes which are convertible at the option of the holders at any time prior to maturity into shares of Quantum common stock at a conversion price of $4.33 per share. Both the 4.50% and the 3.50% notes, if converted, would increase shares outstanding.
In June 2009, we issued a warrant to EMC Corporation to purchase 10 million shares of our common stock at a $0.38 per share exercise price. Only in the event of a change of control of Quantum will this warrant vest and be exercisable. The warrant expires seven years from the date of issuance or three years after change of control, whichever occurs first. Due to these terms, no share-based compensation expense related to this warrant has been recorded to date.

Dilutive and potentially dilutive common shares from stock incentive plans are determined by applying the treasury stock method to the assumed exercise of outstanding options and the assumed vesting of outstanding restricted stock units. The dilutive impact related to our convertible subordinated notes is determined by applying the if-converted method, which includes adding the related weighted average shares to the denominator and the related interest expense to net income.

The computations of diluted net income (loss) per share for the periods presented exclude the following because the effect would have been anti-dilutive:
•
For fiscal 2015, 2014 and 2013, there were 29.0 million, 31.1 million and 31.2 million, respectively, of weighted average shares related to the 3.50% convertible subordinated notes that were excluded. For fiscal 2015, 2014 and 2013, $5.3 million, $5.7 million and $5.7 million, respectively, of related interest expense was excluded.
•
For fiscal 2015, 2014 and 2013, there were 42.5 million, 42.5 million and 17.6 million, respectively, of weighted average shares related to the 4.50% of convertible subordinated notes that were excluded. For fiscal 2015, 2014 and 2013, $3.6 million, $3.6 million and $1.5 million, respectively, of related interest expense was excluded.
•
Stock options to purchase 2.4 million, 12.8 million and 17.3 million weighted average shares in fiscal 2015, 2014 and 2013, respectively, were excluded.
•
Unvested restricted stock units of less than 0.1 million, 11.0 million, and 10.1 million weighted average shares for fiscal 2015, 2014 and 2013, respectively, were excluded.
