Applicable Accounting Guidance

Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative nongovernmental United States generally accepted accounting principles as found in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”).

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended January 31, 2013 included in the Company’s Annual Report on Form 10-K. These financial statements reflect all adjustments (consisting solely of normal, recurring adjustments) that are, in the opinion of management, necessary for a fair statement of results for the interim periods presented.

Change in Estimates

Property and equipment are stated at cost. Major renewals, additions and betterments are charged to equipment accounts while replacements, maintenance and repairs which do not improve or extend the lives of the respective assets are expensed in the period incurred. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in income from operations. Depreciation is computed using the straight-line method over the estimated useful life of each asset.

The Company periodically reviews the estimated useful lives of property and equipment. Changes to the estimated useful lives are recorded prospectively from the date of the change. During the first quarter of fiscal year 2014, the Company reevaluated its network assets, consisting primarily of server equipment utilized in its data centers, and determined that the expected average useful life of those assets had increased from three to five years. The net book value of server assets placed in service as of February 1, 2013 was approximately $2,755. This change resulted in a decrease in depreciation expense on these assets of approximately $142, or $0.01 per share, and $325, or $0.02 per share, on an after-tax basis, for the three and nine months ended October 31, 2013, respectively.
