Equity Participation Right

10. Equity Participation Right

In July 2009, the Company entered into a Bridge Loan and Security Agreement with a related party. In connection with its entry into that agreement, the Company granted to the related party the right to invest up to $10,000 at a 15% discount in the next equity investment round of the Company (if any), by either converting the existing debt or participating with a cash investment (the “Equity Participation Right”). The Equity Participation Right was deemed to be a derivative instrument and was recorded as a liability with a carrying amount equal to its fair value.

Effective upon the consummation of the Company’s initial public offering on July 3, 2012, the Equity Participation Right expired, and the remaining fair value was reduced to zero, resulting in a $276 gain recorded in other income (expense), net in the accompanying consolidated statement of operations for the fiscal year ended January 31, 2013.
