Revenue recognition<br />

We recognize revenue when it is realized or realizable and earned. We consider revenue realized or realizable and<br />

earned when there exists persuasive evidence of an arrangement, the product has been delivered or the services<br />

have been provided to the customer, the sales price is fixed or determinable and collectibility is reasonably<br />

assured.<br />

In recognizing revenue, we make estimates and assumptions on factors such as the probability of collection of the<br />

revenue from the customer, the amount of revenue to allocate to individual elements in a multiple element<br />

arrangement and other matters. We make these estimates and assumptions using our past experience, taking into<br />

account any other current information that may be relevant. These estimates and assumptions may differ from the<br />

actual outcome for a given customer which could impact operating results in a future period.<br />

Government Grants<br />

Government grants relating to costs are deferred and recognized in the income statement as a reduction of expense<br />

over the period necessary to match them with the costs that they are intended to compensate.<br />

Long-Lived Assets<br />

We test long-lived assets for recoverability when events or changes in circumstances indicate evidence of<br />

impairment.<br />

Intangible assets are amortized on a straight-line basis over their estimated useful lives. An impairment loss is<br />

recognized when the estimate of undiscounted future cash flows generated by such assets is less than the carrying<br />

amount. Measurement of the impairment loss is based on the present value of the expected future cash flows. Our<br />

impairment analysis contains estimates due to the inherently speculative nature of forecasting long-term estimated<br />

cash flows and determining the ultimate useful lives of assets. Actual results will differ, which could materially<br />

impact our impairment assessment.<br />

In the case of goodwill, we test for impairment at least annually at October 31 st of each year and at any other time<br />

if any event occurs or circumstances change that would more likely than not reduce our enterprise value below<br />

our carrying amount. Application of the goodwill impairment test requires judgment, including the identification<br />

of reporting units, assigning assets and liabilities to reporting units, assigning goodwill to reporting units, and<br />

determining the fair value of each reporting unit. Significant judgments required to estimate the fair value of<br />

reporting units include estimating future cash flows, determining appropriate discount rates and other<br />

assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value<br />

and/or goodwill impairment for each reporting unit.<br />

Stock-based compensation<br />

We adopted ASC Topic 718, effective February 1, 2006 using the modified prospective application method.<br />

Accordingly, the fair value of that portion of employee stock options that is ultimately expected to vest has been<br />

amortized to expense in our consolidated statement of operations since February 1, 2006 based on the straight-line<br />

attribution method.<br />

The fair value of stock option grants is calculated using the Black-Scholes option-pricing model. Expected<br />

volatility is based on historical volatility of our common stock and other factors. The risk-free interest rates are<br />

based on the Government of Canada average bond yields for a period consistent with the expected life of the<br />

option in effect at the time of the grant. The expected option life is based on the historical life of our granted<br />

options and other factors.<br />

Income Taxes<br />

We have provided for income taxes based on information that is currently available to us. Tax filings are subject<br />

to audits, which could materially change the amount of current and deferred income tax assets and liabilities. As<br />

at January 31, 2011, we had recorded net deferred tax assets of $37.9 million on our consolidated balance sheet<br />
