[1] This adjustment compensates for the effects of the if-converted impact of convertible notes in adjusted net income. Since an entity using the if-converted method assumes that a convertible debt instrument was converted into common shares at the beginning of the reporting period, the numerator is adjusted to reverse any recognized interest expense (including any amortization of discounts).
