__________________

(1) The Company’s annuity and life contracts with guarantees may offer more than one type of guarantee in each contract. Therefore, the amounts listed above may not be mutually exclusive.

(2) Includes amounts, which are not reported on the consolidated balance sheets, from assumed variable annuity guarantees from the Company’s former operating joint venture in Japan.

(3) Includes the contractholder’s investments in the general account and separate account, if applicable.

(4) Defined as the death benefit less the total account value, as of the balance sheet date. It represents the amount of the claim that the Company would incur if death claims were filed on all contracts on the balance sheet date and includes any additional contractual claims associated with riders purchased to assist with covering income taxes payable upon death.

(5) Defined as the amount (if any) that would be required to be added to the total account value to purchase a lifetime income stream, based on current annuity rates, equal to the minimum amount provided under the guaranteed benefit. This amount represents the Company’s potential economic exposure to such guarantees in the event all contractholders were to annuitize on the balance sheet date, even though the contracts contain terms that allow annuitization of the guaranteed amount only after the 10th anniversary of the contract, which not all contractholders have achieved.

(6) Defined as either the excess of the upper tier, adjusted for a profit margin, less the lower tier, as of the balance sheet date or the amount (if any) that would be required to be added to the total account value to purchase a lifetime income stream, based on current annuity rates, equal to the minimum amount provided under the guaranteed benefit. These amounts represent the Company’s potential economic exposure to such guarantees in the event all contractholders were to annuitize on the balance sheet date.

(7) Defined as the guarantee amount less the account value, as of the balance sheet date. It represents the amount of the claim that the Company would incur if death claims were filed on all contracts on the balance sheet date.

The applicable subsidiary of the Company is permitted to withdraw any portion of the collateral in the custody of such FHLBank as long as there is no event of default and the remaining qualified collateral is sufficient to satisfy the collateral maintenance level. Upon any event of default by such subsidiary, the applicable FHLBank’s recovery on the collateral is limited to the amount of such subsidiary’s liability to such FHLBank.

(1) Reflects the accumulated adjustment, net of reinsurance, upon implementation of the short-duration contracts guidance which clarified the requirement to include claim information for long-duration contracts. The accumulated adjustment primarily reflects unpaid claim liabilities, net of reinsurance, for long-duration contracts as of the beginning of the period presented.

(2) During 2018 and 2017, claims and claim adjustment expenses associated with prior years increased due to events incurred in prior years but reported during current year. During 2016, claims and claim adjustment expenses associated with prior years increased due to the implementation of guidance related to short-duration contracts.
