Schedule of Minimum Guaranteed Benefit Liabilities [Table Text Block]

Certain variable annuity and variable universal life contracts in our separate accounts and in variable business we have assumed through reinsurance partners have minimum interest guarantees on funds deposited in our general account. In addition, we have certain variable annuity contracts that include a) guaranteed minimum death benefits (GMDB), b) an incremental death benefit (IDB) rider that pays a percentage of the gain on the contract upon the death of the contract holder, and/or c) a guaranteed minimum income benefit (GMIB) that provides monthly income to the contract holder after the eighth policy year.

GMDB, IDB and GMIB Net Amount at Risk by Type of Guarantee
	December 31, 2016				December 31, 2015
	Separate Account Balance		Net Amount at Risk		Separate Account Balance		Net Amount at Risk
	(Dollars in thousands)
Guaranteed minimum death benefit:
Return of net deposits	$	159,617	$	543	$	175,286	$	623
Return the greater of highest anniversary value or net deposits	270,539		2,920		279,981		14,858
Incremental death benefit	241,142		53,933		256,929		50,159
Guaranteed minimum income benefit	32,733		—		37,334		—
Total			$	57,396			$	65,640

The separate account assets are primarily comprised of stock and bond mutual funds. The net amount at risk for these contracts is based on the amount by which GMDB, IDB or GMIB exceeds account value. The reserve for GMDBs, IDBs or GMIBs, determined using modeling techniques and industry mortality assumptions, that is included in future policy benefits, totaled $5.8 million at December 31, 2016 and $5.4 million at December 31, 2015. The weighted average age of the contract holders with GMDB, IDB or GMIB rider exposure was 62 years at December 31, 2016 and 57 years at December 31, 2015. Benefits paid for GMDBs, IDBs and GMIBs totaled $0.5 million for 2016, $0.4 million for 2015 and $0.2 million for 2014.
