Well your second milestone has already been reached!!!
2006 Final Dividend - Paid 31/05/2007 5.40p
2014 Interim Dividend - Paid 21/10/2014 5.60p
Onwards and upwards!!!
It's got nothing to do with being all doom and gloom, a share will naturally drop by the amount of the dividend, (or thereabouts), as it reflects the reduced MCAP.
