Unearned income, a subset of collected income, is income that has been collected but not yet earned.
Deferred income is income due after the Annual Statement date but before the next policy anniversary.
Uncollected income (due income) is income that is scheduled for receipt before December 31, but which the insurer has not received as of December 31.
Accrued income is income that the insurer has already earned but which is not receivable until a specified date in the next fiscal year (that is, after December 31).
