Orbit Garant 2012 annual rep O rt 23 Earnings per share Earnings per share are calculated using the weighted daily average number of shares outstanding during the year. Diluted earni ngs per share are determined as net earnings, divided by the weighted average number of diluted common shares for the period. Diluted c ommon shares refect the potential dilutive effect of exercising the stock options based on the treasury stock method. Stock options The Company uses the fair value method to account for stock options. In accordance with this method, compensation cost is meas ured at the fair value of the option at the grant date using the Black-Scholes option pricing model and is amortized to earnings over the vesting period. The fair value is recognized as an expense with a corresponding increase in equity settled reserve. The amount recogni zed as an expense is adjusted to refect the number of stock options expected to vest. When unexercised stock options are forfeited or ex pired, the amounts are transferred to retained earnings. TRANSITION TO IFRS The consolidated fnancial statements are prepared in accordance with IFRS, as described under accounting policies (note 3 ). The date of the opening balance sheet under IFRS and the Company’s date of transition to IFRS is July 1, 2010. The IFRS 1 requires the pres entation of Comparative Financial Information and imposes to the First-time adopters to apply, retrospectively, all the IFRS standards i n effect for the Company, for the year ended June 30, 2012. However, it provides certain optional exemptions and certain mandatory excepti ons for the First-time IFRS adopters. Prior to the adoption of IFRS, for all periods up to and including the year ended June 3 0, 2010, the Company’s consolidated fnancial statements were prepared in accordance with Canadian GAAP. The Company applied IFRS 1 First-time Adoption of IFRS to prepare its frst consolidated fnancial statements. The transition incidence to IFRS on equity, net earnings, comprehensive earnings and cas h fows is presented and described in this note and is explained in more detail in the notes relative to the chart.

The Company is required to establish IFRS accounting policies as of the transition date and, in general, to apply these retrospectively to determine the IFRS opening bal ance sheet at July 1, 2010. This Standard provides a number of mandatory exceptions and optional exemptions to this general principl e of retrospective application when the translation of Canadian GAAP to IFRS for the Company. Descriptions of applicable exemptions and exceptions are set out below, together with the Company’s elections: Mandatory exceptions to IFRS adopted by the Company Estimates — In accordance with IFRS 1, an entity’s estimates under IFRS as of the transition date to IFRS must be consistent with estimates made for the same date under previous Canadian GAAP, unless there is objective evidence that those estimates were i n error. The estimates previously made by the Company under Canadian GAAP were not revised on the application of IFRS. Optional choices applied by the Company Business Combinations — IFRS 1 provides the option to apply IFRS 3R (revised), Business Combinations , retrospectively or prospectively from the transition date. A retrospective basis would require restatement of al l business combinations that occurred prior to the transition date.

Accordingly, IAS 27, Consolidated and Separate Financial Statements, is also applied prospectively. Any goodwill arising on acquisition differences has not been adjusted from the carrying value previously determi ned under Canadian GAAP as a result of applying this exemption.
