The Company has stock options, performance share units and restricted stock units granted under various stock incentive plans that, upon exercise and vesting, respectively, would increase shares outstanding. The Company had Convertible Notes, which were convertible at the option of the holders at any time prior to maturity into shares of Quantum common stock. During November 2017, the Company paid all outstanding principal and accrued interest on the Convertible Notes. The Company has also issued warrants to purchase shares of the Company’s stock that are related to the TCW Term Loan and the Senior Secured Term Loan as described within Note 5: to the consolidated financial statements.

The following table sets forth the computation of basic and diluted net loss per share, as adjusted for the Reverse Stock Split (in thousands, except per-share data):

 

The dilutive impact related to common shares from stock incentive plans and outstanding warrants is determined by applying the treasury stock method to the assumed vesting of outstanding performance share units and restricted stock units and the exercise of outstanding options and warrants. The dilutive impact related to common shares from contingently issuable performance share units is determined by applying a two-step approach using both the contingently issuable share guidance and the treasury stock method. 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.

For the year ended March 31, 2017, interest expense related to the convertible subordinated notes of $3.5 million was excluded from the calculation of diluted net loss per share as the shares related to convertible subordinated notes were anti-dilutive.
