Investor Presentation

April 2015

Exhibit 99.1

Safe Harbor Statement

Today’s presentation includes forward-looking statements intended to qualify for

the Safe Harbor from liability established by the Private Securities Litigation

Reform Act of 1995.These forward-looking statements, including statements

regarding our financial expectations, demand for our solutions and growth in our

markets, are subject to risks, uncertainties and other factors that could cause

actual results to differ materially from those suggested by our forward-looking

statements. These factors include, but are not limited to, the risk factors

described in our Annual Report on Form 10-K for the year ended January 31, 2015,

as filed with the SEC on March 24, 2015. Forward-looking information in this

presentation represents our outlook as of today, and we do not undertake any

obligation to update these forward-looking statements.

During today's presentation we may refer to our Adjusted EBITDA.

This is a non-

GAAP financial measure that has been adjusted for certain non-cash and other

items, and that is not computed in accordance with generally accepted accounting

principles. The GAAP measure most comparable to Adjusted EBITDA is our net

income (loss). A reconciliation of our historical Adjusted EBITDA to our net income

(loss) is included in our Form 10-K filed with the SEC.

To supplement our consolidated financial statements, which are presented on a GAAP basis, we disclose Non-GAAP Operating (Loss) Income and Adjusted EBITDA, non-GAAP

measures that exclude certain amounts. These non-GAAP measures are not in accordance with, or an alternative for, generally accepted accounting principles in the United States.

The GAAP measures most comparable to Non-GAAP Operating (Loss) Income and Adjusted EBITDA are GAAP (loss) income from operations and GAAP net (loss) income, respectively.

Reconciliations of these non-GAAP financial measures to the corresponding GAAP measures are included above.

We define non-GAAP operating (loss) income as GAAP operating (loss) income excluding non-cash, stock-based compensation expense and amortization of acquired intangible

assets. We define EBITDA as net (loss) income, excluding depreciation and amortization, interest expense, loss on extinguishment of debt, other income (expense), foreign

exchange gain (loss) and provision for income taxes. We define Adjusted EBITDA as EBITDA, excluding non-cash share-based compensation expense.
