Correction of immaterial errors

An error was identified during the preparation and review of the second quarter, July 31, 2017, financial statements, as stock-based compensation cost and additional paid in capital had been reversed for vested equity awards that expired, terminated or were unexercised. The cumulative adjustment for the stock-based compensation cost covering the period from May 1, 2015 to January 31, 2016 was approximately $0.8 million. The adjustments applicable to the fiscal year ending January 31, 2017 were approximately $0.8 million.

Pursuant to the guidance of Staff Accounting Bulletin ("SAB") No. 99, Materiality, the Company concluded that the errors were not material to any of its prior period financial statements. The prior period financial statements were revised, in accordance with SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements.
