Why does the DPS in the StockReport not match the dividend history?

One likely explanation is that the values in the financial summary are split-adjusted, whereas the numbers in the detailed dividend summary are "raw".

Adjusting DPS for Splits

If there have been a number of recent share issues/splits for a business, we factor this into the numbers. This aids historical comparability across years.

Worked Example

If we take the example of Melrose Plc, the stated DPS in the Annual reports is 7.7p (2009); 11p (2010) and 13p (2011) but the numbers in the stock report will be 5.58p (2009); 7.96p (2010) and 7.4p (2011)

The value of 5.58p for year 2009 results from applying split factor 1.757837 and 0.78571. Calculation: 2009 dividend 5.58p = 7.7/1.757837 (split factor 2011) = 4.38 / 0.78571 (split factor 2010)

The value of 7.96p for year 2010 results from applying split factor 1.757837 and 0.78571. Calculation: 2010 dividend 7.96p = 11 /1.757837 (split factor 2011) = 6.2576 / 0.78571 (split factor 2010)

The value of 7.4p for year (2011) results from applying split factor 1.757837. Calculation: 2011 dividend 7.4p = 13 /1.757837 (split factor 2011) = 7.4
