zzzz1,
Small correction to one of your sentences:
"Ex date for the coming distribution of 0.75 cents will be 31 March 2009"
The MOF website says ex-distribution date is 25 March 2009. Record date is the 31th and pay date is the 30th of April. Based on the September quarter dates, I estimate we will get a routine formal announcement six days before, being the morning of the 19th.
