Remoak..You only partially answered my question and then only in an abstract way.
If the margins were not there I hardly doubt that an organisation would want to borrow around 80% of the total amount if they thought the business was not a good one or that it's potential to earn was decreasing.
Even if they had the intention of splitting the company up,they would have trouble selling parts if the margins and profits were on the downward slide.
Secondly,If the margins are decreasing then why did QF make a record profit.It also appears that next years profit will be even larger so the idea that the margins are decreasing does not seem to hold up.
