Average market price of ordinary shares
A4 For the purpose of calculating diluted earnings per share, the average market price of ordinary shares assumed to be issued is calculated on the basis of the average market price of the ordinary shares during the period. Theoretically, every market transaction for an entity's ordinary shares could be included in the determination of the average market price. As a practical matter, however, a simple average of weekly or monthly prices is usually adequate.
A5 Generally, closing market prices are adequate for calculating the average market price. When prices fluctuate widely, however, an average of the high and low prices usually produces a more representative price. The method used to calculate the average market price is used consistently unless it is no longer representative because of changed conditions. For example, an entity that uses closing market prices to calculate the average market price for several years of relatively stable prices might change to an average of high and low prices if prices start fluctuating greatly and the closing market prices no longer produce a representative average price.

Options, warrants and their equivalents
A6 Options or warrants to purchase convertible instruments are assumed to be exercised to purchase the convertible instrument whenever the average prices of both the convertible instrument and the ordinary shares obtainable upon conversion are above the exercise price of the options or warrants. However, exercise is not assumed unless conversion of similar outstanding convertible instruments, if any, is also assumed.
A7 Options or warrants may permit or require the tendering of debt or other instruments of the entity (or its parent or a subsidiary) in payment of all or a portion of the exercise price. In the calculation of diluted earnings per share, those options or warrants have a dilutive effect if (a) the average market price of the related ordinary shares for the period exceeds the exercise price or (b) the selling price of the instrument to be tendered is below that at which the instrument may be tendered under the option or warrant agreement and the resulting discount establishes an effective exercise price below the market price of the ordinary shares obtainable upon exercise. In the calculation of diluted earnings per share, those options or warrants are assumed to be exercised and the debt or other instruments are assumed to be tendered. If tendering cash is more advantageous to the option or warrant holder and the contract permits tendering cash, tendering of cash is assumed. Interest (net of tax) on any debt assumed to be tendered is added back as an adjustment to the numerator.
A8 Similar treatment is given to preference shares that
