If-Converted Method: Earnings Per Share Calculation & Convertible Securities

The correct answer is 'c. beginning of the earliest period reported (or at the time of issuance, if later).'

The 'if-converted' method of computing earnings per share data assumes conversion of convertible securities as of the beginning of the earliest period reported, or at the time of issuance if it is later.

This method assumes that the convertible securities were converted at the beginning of the period or at the time of issuance, and that the resulting common shares were outstanding for the entire period. This allows for a more accurate calculation of earnings per share, as it takes into account the potential dilution from the convertible securities.

Therefore, the correct answer is 'c. beginning of the earliest period reported (or at the time of issuance, if later).'
