Earnings per Common Share [Abstract]

Earnings per Common Share

Note 7 — Earnings per Common Share

Basic net income per common share is based upon the weighted average common shares outstanding during the period. Diluted net income per common share is based upon the weighted average number of common shares outstanding, including the dilutive effect, if any, of stock options, warrants and the conversion feature of convertible notes using the treasury stock method.

     The Company’s potentially dilutive shares consist of: (i) vested and unvested stock options that are in-the-money, (ii) unvested RSAs, (iii) warrants that are in-the-money, and (iv) shares potentially issuable upon conversion of the Notes.  The Company calculates and includes in dilutive securities incremental shares issuable related to the Notes to the extent that the conversion value of each note exceeds $1,000.

 A reconciliation of the earnings per share data from a basic to a fully diluted basis is detailed below (amounts in thousands, except per share data):
