Differences in adjustments to the share count related to special dividends and demergers can impair the comparability of earnings per share. Under IFRS, EPS growth depends on whether a stock consolidation accompanies a distribution. However, stock consolidations, by themselves, have no economic impact and should not affect performance metrics.
In Vivendi’s recent distribution of shares in Universal Media Group, the lack of an accompanying stock consolidation resulted in a discontinuity in per share metrics. However, in a similar distribution by GSK, a stock consolidation produced a very different outcome. We explain the problem for investors and how you can adjust to ensure comparability.
