[1] Policies with a GMIB also have a GMDB, however these benefits are not additive. When a policy terminates due to death, any NAR related to GMIB is released. Similarly, when a policy goes into benefit status on a GMIB, its GMDB NAR is released.

Universal life

Liabilities for universal life contracts, in excess of the account balance, some of which contain secondary guarantees, are generally determined by estimating the expected value of benefits and expenses when claims are triggered and recognizing those benefits and expenses over the accumulation period based on total expected assessments. The assumptions used in estimating these liabilities are consistent with those used for amortizing DAC..

Changes in Guaranteed Liability Balances:	Universal Life
($ in millions)	Secondary Guarantees
	September 30,			December 31,
	2013			2012
Liability balance, beginning of period	$	115.8		$	100.6
Incurred	31.9			22.6
Paid	(11.8		)	(9.5		)
Change due to net unrealized gains or losses included in AOCI	(1.8		)	2.1
Assumption unlocking	—			—
Liability balance, end of period	$	134.1		$	115.8

In addition, the universal life block of business has experience which produces profits in earlier periods followed by losses in later periods for which additional reserves are required to be held above the account value liability. These reserves are accrued ratably over historical and anticipated positive income to offset the future anticipated losses. The assumptions used in estimating these liabilities are consistent with those used for amortizing DAC.
