And the float is?

?
In an Insurance Company, float is the premiums they collect but which have not been paid out.
Insurance is an odd business. For example, many things are insured for life, Premiums are collected annually in advance - always in advance - and "float" is that money, sitting there in the Insurance Companies accounts (or more likely, invested & earning money elsewhere).
Think of car insurance. We pay it one year in advance, every year. Those premiums, until a claim arise, become "float".
