Investment risks associated with market value changes are borne by the customers, except to the extent of minimum guarantees made by the Company with respect to certain accounts. Separate account liabilities are not included in the above table as they are reported at contract value and not fair value in the Company’s Consolidated Statements of Financial Position.
(3)
As of December 31, 2016, the net embedded derivative liability position of $5,041 million includes $1,157 million of embedded derivatives in an asset position and $6,198 million of embedded derivatives in a liability position. As of December 31, 2015, the net embedded derivative liability position of $5,205 million includes $655 million of embedded derivatives in an asset position and $5,860 million of embedded derivatives in a liability position.
(4)
Prior period amounts are presented on a basis consistent with the current period presentation, reflecting the adoption of ASU 2015-07.

(1)
Conversely, the impact of a decrease in input would have the opposite impact for the fair value as that presented in the table.
(2)
EBITDA multiples represent multiples of earnings before interest, taxes, depreciation and amortization, and are amounts used when the reporting entity has determined that market participants would use such multiples when pricing the investments.
(3)
For universal life, lapse rates vary based on funding level and other factors. Rates are set to zero when the no lapse guarantee is fully funded and the cash value is zero.
(4)
To reflect NPR, the Company incorporates an additional spread over LIBOR into the discount rate used in the valuation of contracts in a liability position and generally not to those in a contra-liability position. The NPR spread reflects the financial strength ratings of the Company and its affiliates, as these are insurance liabilities and senior to debt. The additional spread over LIBOR is determined by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium.
(5)
Universal life mortality rates are adjusted based on underwriting information. A mortality improvement assumption is also incorporated into the projection.
(6)
For universal life, policyholders are assumed to pay a multiple of commissionable target premium levels (shown above and indicated as "X"). The multiples vary by funding level and policy duration. If the resulting premium in any duration is smaller than the minimum annual premium required to maintain the no-lapse guarantee, policyholders are assumed to pay the minimum annual premium. Policyholders are assumed to stop premium payments once the no-lapse guarantee is fully funded. The range shown as of December 31, 2016 excludes multiples for the first duration since all contracts are beyond the first duration. Assumption ranges for prior periods included first duration multiples.
(7)
Future policy benefits primarily represent general account liabilities for the optional living benefit features of the Company’s variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.
(8)
Lapse rates are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates are also generally assumed to be lower for the period where surrender charges apply.
(9)
The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration, and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal. Range reflects the utilization rate for the vast majority of business with living benefits.
(10)
The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions may vary based on the age of the contractholder, the tax status of the contract and the duration since the contractholder began lifetime withdrawals. As of December 31, 2016, the minimum withdrawal assumption rate is 78% and the maximum withdrawal assumption rate may be greater than 100%. The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%.
(11)
Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 35 to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table.
(12)
Includes assets classified as fixed maturities available-for-sale.
(13)
For universal life, premium payment assumptions vary by funding level. Some policies are assumed to pay the minimum premium required to maintain the no lapse guarantee. Other policies are assumed to pay a multiple of commissionable target premium levels (shown above and indicated as “X”). Policyholders are assumed to stop premium payments once the no lapse guarantee is fully funded.

(1)
Conversely, the impact of a decrease in input would have the opposite impact for the fair value as that presented in the table.
(2)
EBITDA multiples represent multiples of earnings before interest, taxes, depreciation and amortization, and are amounts used when the reporting entity has determined that market participants would use such multiples when pricing the investments.
(3)
For universal life, lapse rates vary based on funding level and other factors. Rates are set to zero when the no lapse guarantee is fully funded and the cash value is zero.
(4)
To reflect NPR, the Company incorporates an additional spread over LIBOR into the discount rate used in the valuation of contracts in a liability position and generally not to those in a contra-liability position. The NPR spread reflects the financial strength ratings of the Company and its affiliates, as these are insurance liabilities and senior to debt. The additional spread over LIBOR is determined by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium.
(5)
Universal life mortality rates are adjusted based on underwriting information. A mortality improvement assumption is also incorporated into the projection.
(6)
For universal life, policyholders are assumed to pay a multiple of commissionable target premium levels (shown above and indicated as "X"). The multiples vary by funding level and policy duration. If the resulting premium in any duration is smaller than the minimum annual premium required to maintain the no-lapse guarantee, policyholders are assumed to pay the minimum annual premium. Policyholders are assumed to stop premium payments once the no-lapse guarantee is fully funded. The range shown as of December 31, 2016 excludes multiples for the first duration since all contracts are beyond the first duration. Assumption ranges for prior periods included first duration multiples.
(7)
Future policy benefits primarily represent general account liabilities for the optional living benefit features of the Company’s variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.
(8)
Lapse rates are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates are also generally assumed to be lower for the period where surrender charges apply.
(9)
The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration, and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal. Range reflects the utilization rate for the vast majority of business with living benefits.
(10)
The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions may vary based on the age of the contractholder, the tax status of the contract and the duration since the contractholder began lifetime withdrawals. As of December 31, 2016, the minimum withdrawal assumption rate is 78% and the maximum withdrawal assumption rate may be greater than 100%. The fair value of the liability will generally increase the closer the withdrawal rate is to 100% and decrease as the withdrawal rate moves further away from 100%.
(11)
Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 35 to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table.
(12)
Includes assets classified as fixed maturities available-for-sale.
(13)
For universal life, premium payment assumptions vary by funding level. Some policies are assumed to pay the minimum premium required to maintain the no lapse guarantee. Other policies are assumed to pay a multiple of commissionable target premium levels (shown above and indicated as “X”). Policyholders are assumed to stop premium payments once the no lapse guarantee is fully funded.

(1)
Effective January 1, 2016, the Company adopted new accounting guidance (ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share or Its Equivalent (Topic 820)), which removes the requirement to categorize within the fair value hierarchy all investments measured at net asset value per share (or its equivalent) as a practical expedient. As a result of the adoption of this new guidance, certain other long-term investments are no longer classified in the fair value hierarchy. The guidance was required to be applied retrospectively, and therefore, prior period amounts have been conformed to the current period presentation. At December 31, 2016 and December 31, 2015, the fair values of these cost method investments were $35 million and $27 million, respectively, which had been previously classified in Level 3 at December 31, 2015. The carrying values of these investments were $32 million and $26 million as of December 31, 2016 and December 31, 2015, respectively.
(2)
Carrying values presented herein differ from those in the Company’s Consolidated Statements of Financial Position because certain items within the respective financial statement captions are not considered financial instruments or out of scope under authoritative guidance relating to disclosures of the fair value of financial instruments. Financial statement captions excluded from the above table are not considered financial instruments.
