They have enough franking credits to pay 10c of dividends on a FF basis. This does not mean the divvy to be paid in the second half of the 2016 calendar year will be 10c. My guess (if PGF is used as a guide) is 1c FF to 1.5c FF. They even state that they have sufficient franking credits to 'over a period of future final and interim dividend periods' pay an AGGREGATE of 10c in fully franked dividends'
(mind you, the heading of the release...'update on inaugural dividend' doesn't particularly help, given the content of the release.)
