General	1. General Basis of presentation The accompanying financial statements include the accounts of Allstate Life Insurance Company of New York (the “Company”), a wholly owned subsidiary of Allstate Life Insurance Company (“ALIC”), which is wholly owned by Allstate Insurance Company (“AIC”). AIC is wholly owned by Allstate Insurance Holdings, LLC, a wholly owned subsidiary of The Allstate Corporation (the “Corporation”). These financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Nature of operations The Company sells traditional, interest-sensitive and variable life insurance and voluntary accident and health insurance products to customers in the State of New York. The Company distributes its products through Allstate exclusive agencies and exclusive financial specialists, and workplace enrolling independent agents. The Company previously offered and continues to have in force fixed annuities such as deferred and immediate annuities. The Company also previously offered variable annuities and all of this business is reinsured. The following table summarizes premiums and contract charges by product. ($ in thousands) 2016 2015 2014 Premiums Traditional life insurance $ 52,333 $ 48,532 $ 44,222 Immediate annuities with life contingencies — 5 240 Accident and health insurance 16,248 14,681 14,608 Total premiums 68,581 63,218 59,070 Contract charges Interest-sensitive life insurance 75,940 74,829 73,151 Fixed annuities 69 119 295 Total contract charges 76,009 74,948 73,446 Total premiums and contract charges $ 144,590 $ 138,166 $ 132,516 The Company has exposure to market risk as a result of its investment portfolio. Market risk is the risk that the Company will incur realized and unrealized net capital losses due to adverse changes in interest rates, credit spreads, equity prices or currency exchange rates. The Company’s primary market risk exposures are to changes in interest rates, credit spreads and equity prices. Interest rate risk is the risk that the Company will incur a loss due to adverse changes in interest rates relative to the interest rate characteristics of its interest bearing assets and liabilities. This risk arises from many of the Company’s primary activities, as it invests substantial funds in interest-sensitive assets and issues interest-sensitive liabilities. Interest rate risk includes risks related to changes in U.S. Treasury yields and other key risk-free reference yields. Credit spread risk is the risk that the Company will incur a loss due to adverse changes in credit spreads. This risk arises from many of the Company’s primary activities, as the Company invests substantial funds in spread-sensitive fixed income assets. Equity price risk is the risk that the Company will incur losses due to adverse changes in the general levels of the equity markets. The Company monitors economic and regulatory developments that have the potential to impact its business. Federal and state laws and regulations affect the taxation of insurance companies and life insurance products. Congress and various state legislatures from time to time consider legislation that would reduce or eliminate the favorable policyholder tax treatment currently applicable to life insurance. Congress and various state legislatures also consider proposals to reduce the taxation of certain products or investments that may compete with life insurance. Legislation that increases the taxation on insurance products or reduces the taxation on competing products could lessen the advantage or create a disadvantage for certain of the Company’s products making them less competitive. Such proposals, if adopted, could have an adverse effect on the Company’s financial position or ability to sell such products and could result in the surrender of some existing contracts and policies. In addition, changes in the federal estate tax laws could negatively affect the demand for the types of life insurance used in estate planning.

Summary of Significant Accounti

Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Investments Fixed income securities include bonds, asset-backed securities (“ABS”), residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”) and redeemable preferred stocks. Fixed income securities, which may be sold prior to their contractual maturity, are designated as available for sale and are carried at fair value. The difference between amortized cost and fair value, net of deferred income taxes and related deferred policy acquisition costs (“DAC”), deferred sales inducement costs (“DSI”) and reserves for life-contingent contract benefits, is reflected as a component of accumulated other comprehensive income. Cash received from calls and make-whole payments is reflected as a component of proceeds from sales and cash received from maturities and pay-downs Mortgage loans are carried at unpaid principal balances, net of unamortized premium or discount and valuation allowances. Valuation allowances are established for impaired loans when it is probable that contractual principal and interest will not be collected. Equity securities primarily include common stocks, exchange traded funds, non-redeemable Investments in limited partnership interests include interests in private equity funds and co-investments, Short-term investments, including commercial paper, U.S. Treasury bills, money market funds and other short-term investments, are carried at fair value. Policy loans are carried at unpaid principal balances. Other investments consist of derivatives. Derivatives are carried at fair value. Investment income primarily consists of interest, dividends, income from limited partnership interests, and income from certain derivative transactions. Interest is recognized on an accrual basis using the effective yield method and dividends are recorded at the ex-dividend pay-downs, Realized capital gains and losses include gains and losses on investment sales, write-downs in value due to other-than-temporary declines in fair value, adjustments to valuation allowances on mortgage loans, periodic changes in fair value and settlements of certain derivatives including hedge ineffectiveness and valuation changes in public securities held in certain limited partnerships. Realized capital gains and losses on investment sales are determined on a specific identification basis. Derivative and embedded derivative financial instruments Derivative financial instruments include equity futures, options, interest rate caps, foreign currency forwards and a reinvestment related risk transfer reinsurance agreement with ALIC that meets the accounting definition of a derivative (see Note 4). Derivatives required to be separated from the host instrument and accounted for as derivative financial instruments (“subject to bifurcation”) are embedded in equity-indexed life contracts and reinsured variable annuity contracts. All derivatives are accounted for on a fair value basis and reported as other investments, other assets, other liabilities and accrued expenses or contractholder funds. The income statement effects of derivatives, including fair value gains and losses and accrued periodic settlements, are reported either in realized capital gains and losses or in a single line item together with the results of the associated asset or liability for which risks are being managed. Embedded derivative instruments subject to bifurcation are also accounted for on a fair value basis and are reported together with the host contract. The change in fair value of derivatives embedded in life and annuity product contracts and subject to bifurcation is reported in contract benefits or interest credited to contractholder funds. Cash flows from embedded derivatives subject to bifurcation are reported consistently with the host contracts within the Statements of Cash Flows. Cash flows from other derivatives are reported in cash flows from investing activities within the Statements of Cash Flows. Securities loaned The Company’s business activities include securities lending transactions, which are used primarily to generate net investment income. The proceeds received in conjunction with securities lending transactions are reinvested in short-term investments. These transactions are short-term in nature, usually 30 days or less. The Company receives cash collateral for securities loaned in an amount generally equal to 102% of the fair value of securities and records the related obligations to return the collateral in other liabilities and accrued expenses. The carrying value of these obligations approximates fair value because of their relatively short-term nature. The Company monitors the market value of securities loaned on a daily basis and obtains additional collateral as necessary under the terms of the agreements to mitigate counterparty credit risk. The Company maintains the right and ability to repossess the securities loaned on short notice. Recognition of premium revenues and contract charges, and related benefits and interest credited Traditional life insurance products consist principally of products with fixed and guaranteed premiums and benefits, primarily term and whole life insurance products. Voluntary accident and health insurance products are expected to remain in force for an extended period and therefore are primarily classified as long-duration contracts. Premiums from these products are recognized as revenue when due from policyholders. Benefits are reflected in contract benefits and recognized over the life of the policy in relation to premiums. Immediate annuities with life contingencies, including certain structured settlement annuities, provide insurance protection over a period that extends beyond the period during which premiums are collected. Premiums from these products are recognized as revenue when received at the inception of the contract. Benefits and expenses are recognized in relation to premiums. Profits from these policies come primarily from investment income, which is recognized over the life of the contract. Interest-sensitive life contracts, such as universal life and single premium life, are insurance contracts whose terms are not fixed and guaranteed. The terms that may be changed include premiums paid by the contractholder, interest credited to the contractholder account balance and contract charges assessed against the contractholder account balance. Premiums from these contracts are reported as contractholder fund deposits. Contract charges consist of fees assessed against the contractholder account balance for the cost of insurance (mortality risk), contract administration and surrender of the contract prior to contractually specified dates. These contract charges are recognized as revenue when assessed against the contractholder account balance. Contract benefits include life-contingent benefit payments in excess of the contractholder account balance. Contracts that do not subject the Company to significant risk arising from mortality or morbidity are referred to as investment contracts. Fixed annuities, including market value adjusted annuities and immediate annuities without life contingencies, are considered investment contracts. Consideration received for such contracts is reported as contractholder fund deposits. Contract charges for investment contracts consist of fees assessed against the contractholder account balance for maintenance, administration and surrender of the contract prior to contractually specified dates, and are recognized when assessed against the contractholder account balance. Interest credited to contractholder funds represents interest accrued or paid on interest-sensitive life and investment contracts. Crediting rates for certain fixed annuities and interest-sensitive life contracts are adjusted periodically by the Company to reflect current market conditions subject to contractually guaranteed minimum rates. Crediting rates for indexed life contracts are generally based on an equity index, such as the Standard & Poor’s 500 Index (“S&P 500”). Interest credited also includes amortization of DSI expenses. DSI is amortized into interest credited using the same method used to amortize DAC. Contract charges for variable life and variable annuity products consist of fees assessed against the contractholder account balances for contract maintenance, administration, mortality, expense and surrender of the contract prior to contractually specified dates. Contract benefits incurred for variable annuity products include guaranteed minimum death, income, withdrawal and accumulation benefits. All of the Company’s variable annuity business is ceded through reinsurance agreements and the contract charges and contract benefits related thereto are reported net of reinsurance ceded. Deferred policy acquisition and sales inducement costs Costs that are related directly to the successful acquisition of new or renewal life insurance and investment contracts are deferred and recorded as DAC. These costs are principally agents’ and brokers’ remuneration and certain underwriting expenses. DSI costs, which are deferred and recorded as other assets, relate to sales inducements offered on sales to new customers, principally on fixed annuity and interest-sensitive life contracts. These sales inducements are primarily in the form of additional credits to the customer’s account balance or enhancements to interest credited for a specified period which are in excess of the rates currently being credited to similar contracts without sales inducements. All other acquisition costs are expensed as incurred and included in operating costs and expenses. Amortization of DAC is included in amortization of deferred policy acquisition costs and is described in more detail below. DSI is amortized into income using the same methodology and assumptions as DAC and is included in interest credited to contractholder funds. For traditional life and voluntary accident and health insurance, DAC is amortized over the premium paying period of the related policies in proportion to the estimated revenues on such business. Assumptions used in the amortization of DAC and reserve calculations are established at the time the policy is issued and are generally not revised during the life of the policy. Any deviations from projected business in force resulting from actual policy terminations differing from expected levels and any estimated premium deficiencies may result in a change to the rate of amortization in the period such events occur. Generally, the amortization periods for these policies approximates the estimated lives of the policies. The Company periodically reviews the recoverability of DAC for these policies on an aggregate basis using actual experience. The Company aggregates traditional life insurance products and immediate annuities with life contingencies in one analysis, and voluntary accident and health insurance in a separate analysis. If actual experience is significantly adverse compared to the original assumptions and a premium deficiency is determined to exist, any remaining unamortized DAC balance would be expensed to the extent not recoverable and the establishment of a premium deficiency reserve may be required. For interest-sensitive life insurance and fixed annuities, DAC and DSI are amortized in proportion to the incidence of the total present value of gross profits, which includes both actual historical gross profits (“AGP”) and estimated future gross profits (“EGP”) expected to be earned over the estimated lives of the contracts. The amortization is net of interest on the prior period DAC balance using rates established at the inception of the contracts. Actual amortization periods generally range from 15-30 10-20 5-10 AGP and EGP primarily consist of the following components: contract charges for the cost of insurance less mortality costs and other benefits; investment income and realized capital gains and losses less interest credited; and surrender and other contract charges less maintenance expenses. The principal assumptions for determining the amount of EGP are mortality, persistency, expenses, investment returns, including capital gains and losses on assets supporting contract liabilities, interest crediting rates to contractholders, and the effects of any hedges. For products whose supporting investments are exposed to capital losses in excess of the Company’s expectations which may cause periodic AGP to become temporarily negative, EGP and AGP utilized in DAC and DSI amortization may be modified to exclude the excess capital losses. The Company performs quarterly reviews of DAC and DSI recoverability for interest-sensitive life and fixed annuity contracts in the aggregate using current assumptions. If a change in the amount of EGP is significant, it could result in the unamortized DAC or DSI not being recoverable, resulting in a charge which is included as a component of amortization of deferred policy acquisition costs or interest credited to contractholder funds, respectively. The DAC and DSI balances presented include adjustments to reflect the amount by which the amortization of DAC and DSI would increase or decrease if the unrealized capital gains or losses in the respective product investment portfolios were actually realized. The adjustments are recorded net of tax in accumulated other comprehensive income. DAC, DSI and deferred income taxes determined on unrealized capital gains and losses and reported in accumulated other comprehensive income recognize the impact on shareholder’s equity consistently with the amounts that would be recognized in the income statement on realized capital gains and losses. Customers of the Company may exchange one insurance policy or investment contract for another offered by the Company, or make modifications to an existing investment or life contract issued by the Company. These transactions are identified as internal replacements for accounting purposes. Internal replacement transactions determined to result in replacement contracts that are substantially unchanged from the replaced contracts are accounted for as continuations of the replaced contracts. Unamortized DAC and DSI related to the replaced contracts continue to be deferred and amortized in connection with the replacement contracts. For interest-sensitive life and investment contracts, the EGP of the replacement contracts are treated as a revision to the EGP of the replaced contracts in the determination of amortization of DAC and DSI. For traditional life insurance policies, any changes to unamortized DAC that result from replacement contracts are treated as prospective revisions. Any costs associated with the issuance of replacement contracts are characterized as maintenance costs and expensed as incurred. Internal replacement transactions determined to result in a substantial change to the replaced contracts are accounted for as an extinguishment of the replaced contracts, and any unamortized DAC and DSI related to the replaced contracts are eliminated with a corresponding charge to amortization of deferred policy acquisition costs or interest credited to contractholder funds, respectively. Reinsurance In the normal course of business, the Company seeks to limit aggregate and single exposure to losses on large risks by purchasing reinsurance. The Company has also used reinsurance to effect the disposition of certain blocks of business. The amounts reported as reinsurance recoverables include amounts billed to reinsurers on losses paid as well as estimates of amounts expected to be recovered from reinsurers on insurance liabilities and contractholder funds that have not yet been paid. Reinsurance recoverables on unpaid losses are estimated based upon assumptions consistent with those used in establishing the liabilities related to the underlying reinsured contracts. Insurance liabilities are reported gross of reinsurance recoverables. Reinsurance premiums are generally reflected in income in a manner consistent with the recognition of premiums on the reinsured contracts. Reinsurance does not extinguish the Company’s primary liability under the policies written. Therefore, the Company regularly evaluates the financial condition of its reinsurers and establishes allowances for uncollectible reinsurance as appropriate. The Company has a reinsurance treaty with ALIC through which it primarily cedes reinvestment related risk on its structured settlement annuities. The terms of the treaty meet the accounting definition of a derivative. Accordingly, the treaty is recorded in the Statement of Financial Position at fair value. Changes in the fair value of the treaty and premiums paid to ALIC are recognized in realized capital gains and losses. Income taxes The income tax provision is calculated under the liability method. Deferred tax assets and liabilities are recorded based on the difference between the financial statement and tax bases of assets and liabilities at the enacted tax rates. The principal assets and liabilities giving rise to such differences are unrealized capital gains and losses, differences in tax bases of invested assets, insurance reserves and DAC. A deferred tax asset valuation allowance is established when there is uncertainty that such assets will be realized. Reserve for life-contingent contract benefits The reserve for life-contingent contract benefits payable under insurance policies, including traditional life insurance, life-contingent immediate annuities and voluntary accident and health insurance products, is computed on the basis of long-term actuarial assumptions of future investment yields, mortality, morbidity, policy terminations and expenses. These assumptions, which for traditional life insurance are applied using the net level premium method, include provisions for adverse deviation and generally vary by characteristics such as type of coverage, year of issue and policy duration. The assumptions are established at the time the policy is issued and are generally not changed during the life of the policy. The Company periodically reviews the adequacy of reserves for these policies on an aggregate basis using actual experience. If actual experience is significantly adverse compared to the original assumptions and a premium deficiency is determined to exist, any remaining unamortized DAC balance would be expensed to the extent not recoverable and the establishment of a premium deficiency reserve may be required. The Company also reviews these policies on an aggregate basis for circumstances where projected profits would be recognized in early years followed by projected losses in later years. If this circumstance exists, the Company will accrue a liability, during the period of profits, to offset the losses at such time as the future losses are expected to commence using a method updated prospectively over time. To the extent that unrealized gains on fixed income securities would result in a premium deficiency if those gains were realized, the related increase in reserves for certain immediate annuities with life contingencies is recorded net of tax as a reduction of unrealized net capital gains included in accumulated other comprehensive income. Contractholder funds Contractholder funds represent interest-bearing liabilities arising from the sale of products such as interest-sensitive life insurance and fixed annuities. Contractholder funds primarily comprise cumulative deposits received and interest credited to the contractholder less cumulative contract benefits, surrenders, withdrawals and contract charges for mortality or administrative expenses. Contractholder funds also include reserves for secondary guarantees on interest-sensitive life insurance and certain fixed annuity contracts and reserves for certain guarantees on reinsured variable annuity contracts. Separate accounts Separate accounts assets are carried at fair value. The assets of the separate accounts are legally segregated and available only to settle separate account contract obligations. Separate accounts liabilities represent the contractholders’ claims to the related assets and are carried at an amount equal to the separate accounts assets. Investment income and realized capital gains and losses of the separate accounts accrue directly to the contractholders and therefore are not included in the Company’s Statements of Operations and Comprehensive Income. Deposits to and surrenders and withdrawals from the separate accounts are reflected in separate accounts liabilities and are not included in cash flows. Absent any contract provision wherein the Company provides a guarantee, variable annuity and variable life insurance contractholders bear the investment risk that the separate accounts’ funds may not meet their stated investment objectives. All of the Company’s variable annuity business was reinsured beginning in 2006. Off-balance Commitments to invest, commitments to purchase private placement securities and financial guarantees have off-balance Adopted accounting standard Amendments to the Consolidation Analysis In February 2015, the Financial Accounting Standards Board (“FASB”) issued guidance affecting the consolidation evaluation for limited partnerships and similar entities, fees paid to a decision maker or service provider, and variable interests in a variable interest entity held by related parties of the reporting enterprise. The adoption of this guidance as of January 1, 2016 did not have a material impact on the Company’s results of operations or financial position. Pending accounting standards Recognition and Measurement of Financial Assets and Financial Liabilities In January 2016, the FASB issued guidance requiring equity investments, including equity securities and limited partnership interests, that are not accounted for under the equity method of accounting or result in consolidation to be measured at fair value with changes in fair value recognized in net income. Equity investments without readily determinable fair values may be measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. When a qualitative assessment of equity investments without readily determinable fair values indicates that impairment exists, the carrying value is required to be adjusted to fair value, if lower. The guidance clarifies that an entity should evaluate the realizability of a deferred tax asset related to available-for-sale pre-tax pre-tax, Transition to Equity Method Accounting In March 2016, the FASB issued guidance amending the accounting requirements for transitioning to the equity method of accounting (“EMA”), including a transition from the cost method. The guidance requires the cost of acquiring an additional interest in an investee to be added to the existing carrying value to establish the initial basis of the EMA investment. Under the new guidance, no retroactive adjustment is required when an investment initially qualifies for EMA treatment. The guidance is effective for annual periods beginning after December 15, 2016, and is to be applied prospectively. The guidance will principally affect the future accounting for investments that qualify for EMA after application of the cost method of accounting. The Company is in the process of evaluating the impact of adoption, which is not expected to be material to the Company’s results of operations or financial position. Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued guidance which revises the credit loss recognition criteria for certain financial assets measured at amortized cost. The new guidance replaces the existing incurred loss recognition model with an expected loss recognition model. The objective of the expected credit loss model is for the reporting entity to recognize its estimate of expected credit losses for affected financial assets in a valuation allowance deducted from the amortized cost basis of the related financial assets that results in presenting the net carrying value of the financial assets at the amount expected to be collected. The reporting entity must consider all available relevant information when estimating expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts over the contractual life of an asset. Financial assets may be evaluated individually or on a pooled basis when they share similar risk characteristics. The measurement of credit losses for available-for-sale

Related Party Transactions	4. Related Party Transactions Business operations The Company uses services performed by AIC, ALIC and other affiliates, and business facilities owned or leased and operated by AIC in conducting its business activities. In addition, the Company shares the services of employees with AIC. The Company reimburses its affiliates for the operating expenses incurred on behalf of the Company. The Company is charged for the cost of these operating expenses based on the level of services provided. Operating expenses, including compensation, retirement and other benefit programs (see Note 14), allocated to the Company were $40.0 million, $39.0 million and $44.1 million in 2016, 2015 and 2014, respectively. A portion of these expenses relate to the acquisition of business, which are deferred and amortized into income as described in Note 2. Structured settlement annuities The Company previously issued structured settlement annuities, a type of immediate annuity, to fund structured settlements in matters involving AIC. In most cases, these annuities were issued under a “qualified assignment” whereby Allstate Assignment Company and prior to July 1, 2001 Allstate Settlement Corporation (“ASC”), both wholly owned subsidiaries of ALIC, purchased annuities from the Company and assumed AIC’s obligation to make future payments. AIC issued surety bonds to guarantee the payment of structured settlement benefits assumed by ASC (from both AIC and non-related Broker-Dealer agreements The Company receives distribution services from Allstate Financial Services, LLC, an affiliated broker-dealer company, for certain annuity and variable life insurance contracts sold by Allstate exclusive agencies. For these services, the Company incurred commission and other distribution expenses of $450 thousand, $233 thousand and $166 thousand in 2016, 2015 and 2014, respectively. The Company has a service agreement with Allstate Distributors, LLC (“ADLLC”), a broker-dealer company owned by ALIC, whereby ADLLC promotes and markets products sold by the Company. In return for these services, the Company recorded expense of $4 thousand, $23 thousand and $7 thousand in 2016, 2015 and 2014, respectively. Reinsurance The Company has reinsurance agreements with ALIC whereby a portion of the Company’s premiums and policy benefits are ceded to ALIC (see Note 9). The Company has a reinsurance treaty (the “structured settlement annuity reinsurance agreement”) through which it primarily cedes reinvestment related risk on its structured settlement annuities to ALIC. Under the terms of the treaty, the Company pays a premium to ALIC that varies with the aggregate structured settlement annuity statutory reserve balance. In return, ALIC guarantees that the yield on the portion of the Company’s investment portfolio that supports structured settlement annuity liabilities will not fall below contractually determined rates. The Company ceded premium related to structured settlement annuities to ALIC of $3.4 million in each 2016, 2015 and 2014. As of December 31, 2016 and 2015, the carrying value of the structured settlement reinsurance treaty was $109.6 million and $82.8 million, respectively, which is recorded in other assets. The premiums ceded and changes in the fair value of the reinsurance treaty are reflected as a component of realized capital gains and losses as the treaty is recorded as a derivative instrument. Income taxes The Company is a party to a federal income tax allocation agreement with the Corporation (see Note 12). Intercompany loan agreement The Company has an intercompany loan agreement with the Corporation. The amount of intercompany loans available to the Company is at the discretion of the Corporation. The maximum amount of loans the Corporation will have outstanding to all its eligible subsidiaries at any given point in time is limited to $1 billion. The Corporation may use commercial paper borrowings, bank lines of credit and securities lending to fund intercompany borrowings. The Company had no amounts outstanding under the intercompany loan agreement as of December 31, 2016 or 2015.

The determination of cash flow estimates is inherently subjective and methodologies may vary depending on facts and circumstances specific to the security. All reasonably available information relevant to the collectability of the security, including past events, current conditions, and reasonable and supportable assumptions and forecasts, are considered when developing the estimate of cash flows expected to be collected. That information generally includes, but is not limited to, the remaining payment terms of the security, prepayment speeds, foreign exchange rates, the financial condition and future earnings potential of the issue or issuer, expected defaults, expected recoveries, the value of underlying collateral, vintage, geographic concentration of underlying collateral, available reserves or escrows, current subordination levels, third party guarantees and other credit enhancements. Other information, such as industry analyst reports and forecasts, sector credit ratings, financial condition of the bond insurer for insured fixed income securities, and other market data relevant to the realizability of contractual cash flows, may also be considered. The estimated fair value of collateral will be used to estimate recovery value if the Company determines that the security is dependent on the liquidation of collateral for ultimate settlement. If the estimated recovery value is less than the amortized cost of the security, a credit loss exists and an other-than-temporary impairment for the difference between the estimated recovery value and amortized cost is recorded in earnings. The portion of the unrealized loss related to factors other than credit remains classified in accumulated other comprehensive income. If the Company determines that the fixed income security does not have sufficient cash flow or other information to estimate a recovery value for the security, the Company may conclude that the entire decline in fair value is deemed to be credit related and the loss is recorded in earnings.

Fair value and gross unrealized gains and losses are not applicable. (2) The insurance reserves adjustment represents the amount by which the reserve balance would increase if the net unrealized gains in the applicable product portfolios were realized and reinvested at current lower interest rates, resulting in a premium deficiency. Although the Company evaluates premium deficiencies on the combined performance of life insurance and immediate annuities with life contingencies, the adjustment primarily relates to structured settlement annuities with life contingencies, in addition to certain payout annuities with life contingencies.

For each fixed income security in an unrealized loss position, the Company assesses whether management with the appropriate authority If the Company has not made the decision to sell the fixed income security and it is not more likely than not the Company will be required to sell the fixed income security before recovery of its amortized cost basis, the Company evaluates whether it expects to receive cash flows sufficient to recover the entire amortized cost basis of the security. The Company calculates the estimated recovery value by discounting the best estimate of future cash flows at the security’s original or current effective rate, as appropriate, and compares this to the amortized cost of the security. If the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the fixed income security, the credit loss component of the impairment is recorded in earnings, with the remaining amount of the unrealized loss related to other factors recognized in other comprehensive income. For equity securities, the Company considers various factors, including whether it has the intent and ability to hold the equity security for a period of time sufficient to recover its cost basis. Where the Company lacks the intent and ability to hold to recovery, or believes the recovery period is extended, the equity security’s decline in fair value is considered other than temporary and is recorded in earnings. For fixed income and equity securities managed by third parties, either the Company has contractually retained its decision making authority as it pertains to selling securities that are in an unrealized loss position or it recognizes any unrealized loss at the end of the period through a charge to earnings. The Company’s portfolio monitoring process includes a quarterly review of all securities to identify instances where the fair value of a security compared to its amortized cost (for fixed income securities) or cost (for equity securities) is below established thresholds. The process also includes the monitoring of other impairment indicators such as ratings, ratings downgrades and payment defaults. The securities identified, in addition to other securities for which the Company may have a concern, are evaluated for potential other-than-temporary impairment using all reasonably available information relevant to the collectability or recovery of the security. Inherent in the Company’s evaluation of other-than-temporary impairment for these fixed income and equity securities are assumptions and estimates about the financial condition and future earnings potential of the issue or issuer. Some of the factors that may be considered in evaluating whether a decline in fair value is other than temporary are: 1) the financial condition, near-term and long-term prospects of the issue or issuer, including relevant industry specific market conditions and trends, geographic location and implications of rating agency actions and offering prices; 2) the specific reasons that a security is in an unrealized loss position, including overall market conditions which could affect liquidity; and 3) the length of time and extent to which the fair value has been less than amortized cost or cost. The following table summarizes the gross unrealized losses and fair value of fixed income and equity securities by the length of time that individual securities have been in a continuous unrealized loss position.

Of the $26.1 million, $19.7 million are related to unrealized losses on investment grade fixed income securities and $3.7 million are related to equity securities. Of the remaining $2.7 million, $1.9 million have been in an unrealized loss position for less than 12 months. Investment grade is defined as a security having a rating of Aaa, Aa, A or Baa from Moody’s, a rating of AAA, AA, A or BBB from S&P Global Ratings (“S&P”), a comparable rating from another nationally recognized rating agency, or a comparable internal rating if an externally provided rating is not available. Market prices for certain securities may have credit spreads which imply higher or lower credit quality than the current third party rating. Unrealized losses on investment grade securities are principally related to an increase in market yields which may include increased risk-free interest rates and/or wider credit spreads since the time of initial purchase. As of December 31, 2016, the remaining $7.6 million of unrealized losses are related to securities in unrealized loss positions greater than or equal to 20% of amortized cost or cost. Of the $7.6 million, $3.5 million are related to below investment grade fixed income securities and $4.1 million are related to equity securities. ABS, RMBS and CMBS in an unrealized loss position were evaluated based on actual and projected collateral losses relative to the securities’ positions in the respective securitization trusts, security specific expectations of cash flows, and credit ratings. This evaluation also takes into consideration credit enhancement, measured in terms of (i) subordination from other classes of securities in the trust that are contractually obligated to absorb losses before the class of security the Company owns, (ii) the expected impact of other structural features embedded in the securitization trust beneficial to the class of securities the Company owns, such as overcollateralization and excess spread, and (iii) for ABS and RMBS in an unrealized loss position, credit enhancements from reliable bond insurers, where applicable. Municipal bonds in an unrealized loss position were evaluated based on the underlying credit quality of the primary obligor, obligation type and quality of the underlying assets. Unrealized losses on equity securities are primarily related to temporary equity market fluctuations of securities that are expected to recover. As of December 31, 2016, the Company has not made the decision to sell and it is not more likely than not the Company will be required to sell fixed income securities with unrealized losses before recovery of the amortized cost basis. As of December 31, 2016, the Company had the intent and ability to hold equity securities with unrealized losses for a period of time sufficient for them to recover. Limited partnerships As of December 31, 2016 and 2015, the carrying value of equity method limited partnerships totaled $257.8 million and $216.6 million, respectively. The Company recognizes an impairment loss for equity method limited partnerships when evidence demonstrates that the loss is other than temporary. Evidence of a loss in value that is other than temporary may include the absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain a level of earnings that would justify the carrying amount of the investment. As of December 31, 2016 and 2015, the carrying value for cost method limited partnerships was $72.5 million and $64.5 million, respectively. To determine if an other-than-temporary impairment has occurred, the Company evaluates whether an impairment indicator has occurred in the period that may have a significant adverse effect on the carrying value of the investment. Impairment indicators may include: significantly reduced valuations of the investments held by the limited partnerships; actual recent cash flows received being significantly less than expected cash flows; reduced valuations based on financing completed at a lower value; completed sale of a material underlying investment at a price significantly lower than expected; or any other adverse events since the last financial statements received that might affect the fair value of the investee’s capital. Additionally, the Company’s portfolio monitoring process includes a quarterly review of all cost method limited partnerships to identify instances where the net asset value is below established thresholds for certain periods of time, as well as investments that are performing below expectations, for further impairment consideration. If a cost method limited partnership is other-than-temporarily impaired, the carrying value is written down to fair value, generally estimated to be equivalent to the reported net asset value. Mortgage loans The Company’s mortgage loans are commercial mortgage loans collateralized by a variety of commercial real estate property types located across the United States and totaled, net of valuation allowance, $614.4 million and $614.2 million as of December 31, 2016 and 2015, respectively. Substantially all of the commercial mortgage loans are non-recourse The following table shows the principal geographic distribution of commercial real estate represented in the Company’s mortgage loan portfolio. No other state represented more than 5% of the portfolio as of December 31.

Mortgage loans are considered impaired when it is probable that the Company will not collect the contractual principal and interest. Valuation allowances are established for impaired loans to reduce the carrying value to the fair value of the collateral less costs to sell or the present value of the loan’s expected future repayment cash flows discounted at the loan’s original effective interest rate. Impaired mortgage loans may not have a valuation allowance when the fair value of the collateral less costs to sell is higher than the carrying value. Valuation allowances are adjusted for subsequent changes in the fair value of the collateral less costs to sell or present value of the loan’s expected future repayment cash flows. Mortgage loans are charged off against their corresponding valuation allowances when there is no reasonable expectation of recovery. The impairment evaluation is non-statistical Accrual of income is suspended for mortgage loans that are in default or when full and timely collection of principal and interest payments is not probable. Cash receipts on mortgage loans on nonaccrual status are generally recorded as a reduction of carrying value. Debt service coverage ratio is considered a key credit quality indicator when mortgage loans are evaluated for impairment. Debt service coverage ratio represents the amount of estimated cash flows from the property available to the borrower to meet principal and interest payment obligations. Debt service coverage ratio estimates are updated annually or more frequently if conditions are warranted based on the Company’s credit monitoring process. The following table reflects the carrying value of non-impaired ($ in thousands) 2016 2015 Below 1.0 $ 5,600 $ 14,408 1.0 - 1.25 44,289 35,301 1.26 - 1.50 179,503 194,795 Above 1.50 384,988 369,680 Total non-impaired $ 614,380 $ 614,184 Mortgage loans with a debt service coverage ratio below 1.0 that are not considered impaired primarily relate to instances where the borrower has the financial capacity to fund the revenue shortfalls from the properties for the foreseeable term, the decrease in cash flows from the properties is considered temporary, or there are other risk mitigating circumstances such as additional collateral, escrow balances or borrower guarantees. There were no impaired mortgage loans as of December 31, 2016 or 2015. The average balance of impaired loans was $2.4 million during 2014. The rollforward of the valuation allowance on impaired mortgage loans for the years ended December 31 is as follows: ($ in thousands) 2016 2015 2014 Beginning balance $ — $ — $ 1,832 Net decrease in valuation allowance — — (1,110 ) Charge offs — — (722 ) Ending balance $ — $ — $ — Payments on all mortgage loans were current as of December 31, 2016 and 2015.

Securities loaned The Company’s business activities include securities lending programs with third parties, mostly large banks. As of December 31, 2016 and 2015, fixed income and equity securities with a carrying value of $59.2 million and $96.5 million, respectively, were on loan under these agreements. Interest income on collateral, net of fees, was $306 thousand, $235 thousand and zero in 2016, 2015 and 2014, respectively. Other investment information Included in fixed income securities are below investment grade assets totaling $269.2 million and $269.8 million as of December 31, 2016 and 2015, respectively. As of December 31, 2016, fixed income securities with a carrying value of $2.3 million were on deposit with regulatory authorities as required by law. As of December 31, 2016, there were no fixed income securities that were non-income The Company had $2.4 million and $4.7 million of investment-related debt that is reported in other liabilities and accrued expenses as of December 31, 2016 and 2015, respectively, relating to a commitment to fund a limited partnership. The Company has an outstanding line of credit to fund the limited partnership.

Fair Value of Assets and Liabil

Fair Value of Assets and Liabilities	12 Months Ended
	Dec. 31, 2016
Fair Value of Assets and Liabilities	6. Fair Value of Assets and Liabilities Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The hierarchy for inputs used in determining fair value maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Assets and liabilities recorded on the Statements of Financial Position at fair value are categorized in the fair value hierarchy based on the observability of inputs to the valuation techniques as follows: Level 1: Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that the Company can access. Level 2: Assets and liabilities whose values are based on the following: (a) Quoted prices for similar assets or liabilities in active markets; (b) Quoted prices for identical or similar assets or liabilities in markets that are not active; or (c) Valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability. Level 3: Assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Unobservable inputs reflect the Company’s estimates of the assumptions that market participants would use in valuing the assets and liabilities. The availability of observable inputs varies by instrument. In situations where fair value is based on internally developed pricing models or inputs that are unobservable in the market, the determination of fair value requires more judgment. The degree of judgment exercised by the Company in determining fair value is typically greatest for instruments categorized in Level 3. In many instances, valuation inputs used to measure fair value fall into different levels of the fair value hierarchy. The category level in the fair value hierarchy is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company uses prices and inputs that are current as of the measurement date, including during periods of market disruption. In periods of market disruption, the ability to observe prices and inputs may be reduced for many instruments. The Company is responsible for the determination of fair value and the supporting assumptions and methodologies. The Company gains assurance that assets and liabilities are appropriately valued through the execution of various processes and controls designed to ensure the overall reasonableness and consistent application of valuation methodologies, including inputs and assumptions, and compliance with accounting standards. For fair values received from third parties or internally estimated, the Company’s processes and controls are designed to ensure that the valuation methodologies are appropriate and consistently applied, the inputs and assumptions are reasonable and consistent with the objective of determining fair value, and the fair values are accurately recorded. For example, on a continuing basis, the Company assesses the reasonableness of individual fair values that have stale security prices or that exceed certain thresholds as compared to previous fair values received from valuation service providers or brokers or derived from internal models. The Company performs procedures to understand and assess the methodologies, processes and controls of valuation service providers. In addition, the Company may validate the reasonableness of fair values by comparing information obtained from valuation service providers or brokers to other third party valuation sources for selected securities. The Company performs ongoing price validation procedures such as back-testing of actual sales, which corroborate the various inputs used in internal models to market observable data. When fair value determinations are expected to be more variable, the Company validates them through reviews by members of management who have relevant expertise and who are independent of those charged with executing investment transactions. The Company has two types of situations where investments are classified as Level 3 in the fair value hierarchy. The first is where specific inputs significant to the fair value estimation models are not market observable. This primarily occurs in the Company’s use of broker quotes to value certain securities where the inputs have not been corroborated to be market observable, and the use of valuation models that use significant non-market The second situation where the Company classifies securities in Level 3 is where quotes continue to be received from independent third-party valuation service providers and all significant inputs are market observable; however, there has been a significant decrease in the volume and level of activity for the asset when compared to normal market activity such that the degree of market observability has declined to a point where categorization as a Level 3 measurement is considered appropriate. The indicators considered in determining whether a significant decrease in the volume and level of activity for a specific asset has occurred include the level of new issuances in the primary market, trading volume in the secondary market, the level of credit spreads over historical levels, applicable bid-ask Certain assets are not carried at fair value on a recurring basis, including investments such as mortgage loans, limited partnership interests and policy loans. Accordingly, such investments are only included in the fair value hierarchy disclosure when the investment is subject to remeasurement at fair value after initial recognition and the resulting remeasurement is reflected in the financial statements. In determining fair value, the Company principally uses the market approach which generally utilizes market transaction data for the same or similar instruments. To a lesser extent, the Company uses the income approach which involves determining fair values from discounted cash flow methodologies. For the majority of Level 2 and Level 3 valuations, a combination of the market and income approaches is used.

Transfers between level categorizations may occur due to changes in the availability of market observable inputs, which generally are caused by changes in market conditions such as liquidity, trading volume or bid-ask There were no transfers between Level 1 and Level 2 during 2016, 2015 or 2014. Transfers into Level 3 during 2016, 2015 and 2014 included situations where a fair value quote was not provided by the Company’s independent third-party valuation service provider and as a result the price was stale or had been replaced with a broker quote where the inputs had not been corroborated to be market observable resulting in the security being classified as Level 3. Transfers out of Level 3 during 2016, 2015 and 2014 included situations where a broker quote was used in the prior period and a fair value quote became available from the Company’s independent third-party valuation service provider in the current period.

Derivative Financial Instrument

Derivative Financial Instruments and Off-balance sheet Financial Instruments	7. Derivative Financial Instruments and Off-balance The Company uses derivatives for risk reduction focused on managing the risks with certain assets and liabilities arising from the potential adverse impacts from changes in risk-free interest rates, changes in equity market valuations and foreign currency fluctuations. Asset-liability management is a risk management strategy that is principally employed to balance the respective interest-rate sensitivities of the Company’s assets and liabilities. Depending upon the attributes of the assets acquired and liabilities issued, derivative instruments such as interest rate caps are utilized to change the interest rate characteristics of existing assets and liabilities to ensure the relationship is maintained within specified ranges and to reduce exposure to rising or falling interest rates. Futures and options are used for hedging the equity exposure contained in the Company’s equity indexed life product contracts that offer equity returns to contractholders. Foreign currency forwards are primarily used by the Company to reduce the foreign currency risk associated with holding foreign currency denominated investments. The Company also has a reinsurance treaty that is recorded as a derivative instrument, under which it primarily cedes reinvestment related risk on its structured settlement annuities to ALIC. The Company also has derivatives embedded in non-derivative The notional amounts specified in the contracts are used to calculate the exchange of contractual payments under the agreements and are generally not representative of the potential for gain or loss on these agreements. Fair value, which is equal to the carrying value, is the estimated amount that the Company would receive or pay to terminate the derivative contracts at the reporting date. The carrying value amounts for OTC derivatives are further adjusted for the effects, if any, of enforceable master netting agreements and are presented on a net basis, by counterparty agreement, in the Statements of Financial Position. For certain exchange traded derivatives, margin deposits are required as well as daily cash settlements of margin accounts. As of December 31, 2016, the Company pledged $60 thousand of cash in the form of margin deposits.

The Company uses MNAs for OTC derivative transactions that permit either party to net payments due for transactions and collateral is either pledged or obtained when certain predetermined exposure limits are exceeded. As of December 31, 2016, the Company did not have any collateral pledged to or from counterparties. The Company has not incurred any losses on derivative financial instruments due to counterparty nonperformance. Other derivatives, including futures and option contracts, are traded on organized exchanges which require margin deposits and guarantee the execution of trades, thereby mitigating any potential credit risk. Counterparty credit exposure represents the Company’s potential loss if all of the counterparties concurrently fail to perform under the contractual terms of the contracts and all collateral, if any, becomes worthless. This exposure is measured by the fair value of OTC derivative contracts with a positive fair value at the reporting date reduced by the effect, if any, of legally enforceable master netting agreements. The following table summarizes the counterparty credit exposure as of December 31 by counterparty credit rating as it relates to the Company’s OTC derivatives. ($ in thousands) 2016 2015 Rating (1) Number of Notional (2) Credit (2) Exposure, (2) Number of Notional (2) Credit (2) Exposure, (2) A+ 4 $ 34,304 $ 734 $ 734 1 $ 11,800 $ 197 $ 197 A — — — — 3 9,765 125 125 BBB+ — — — — 2 5,665 69 69 Total 4 $ 34,304 $ 734 $ 734 6 $ 27,230 $ 391 $ 391 (1) Rating is the lower of S&P or Moody’s ratings. (2) Only OTC derivatives with a net positive fair value are included for each counterparty. Market risk is the risk that the Company will incur losses due to adverse changes in market rates and prices. Market risk exists for all of the derivative financial instruments the Company currently holds, as these instruments may become less valuable due to adverse changes in market conditions. To limit this risk, the Company’s senior management has established risk control limits. In addition, changes in fair value of the derivative financial instruments that the Company uses for risk management purposes are generally offset by the change in the fair value or cash flows of the hedged risk component of the related assets, liabilities or forecasted transactions. Certain of the Company’s derivative instruments contain credit-risk-contingent termination events, cross-default provisions and credit support annex agreements. Credit-risk-contingent termination events allow the counterparties to terminate the derivative agreement or a specific trade on certain dates if the Company’s financial strength credit ratings by Moody’s or S&P fall below a certain level. Credit-risk-contingent cross-default provisions allow the counterparties to terminate the derivative agreement if the Company defaults by pre-determined Off-balance The contractual amounts of off-balance-sheet off-balance-sheet off-balance Commitments to invest in limited partnership interests represent agreements to acquire new or additional participation in certain limited partnership investments. The Company enters into these agreements in the normal course of business. Because the investments in limited partnerships are not actively traded, it is not practical to estimate the fair value of these commitments. Private placement commitments represent commitments to purchase private placement private equity securities at a specified future date. The Company enters into these agreements in the normal course of business. The fair value of these commitments generally cannot be estimated on the date the commitment is made as the terms and conditions of the underlying private placement securities are not yet final. Because the private equity securities are not actively traded, it is not practical to estimate fair value of the commitments.

(collectively “Prudential”). To the extent that unrealized gains on fixed income securities would result in a premium deficiency had those gains actually been realized, a premium deficiency reserve is recorded for certain immediate annuities with life contingencies. A liability of $56.4 million and $44.4 million is included in the reserve for life-contingent contract benefits with respect to this deficiency as of December 31, 2016 and 2015, respectively. The offset to this liability is recorded as a reduction of the unrealized net capital gains included in accumulated other comprehensive income. As of December 31, contractholder funds consist of the following: ($ in thousands) 2016 2015 Interest-sensitive life insurance $ 728,841 $ 724,317 Investment contracts: Fixed annuities 2,261,237 2,434,757 Other investment contracts 28,655 26,813 Total contractholder funds $ 3,018,733 $ 3,185,887 The following table highlights the key contract provisions relating to contractholder funds: Product Interest rate Withdrawal/surrender charges Interest-sensitive life insurance Interest rates credited range from 0% to 10.5% for equity-indexed life (whose returns are indexed to the S&P 500) and 2.7% to 5.1% for all other products Either a percentage of account Fixed annuities Interest rates credited range from 0% to 9.0% for immediate annuities and 1.0% to 5.0% for other fixed annuities Either a declining or a level Other investment contracts: Guaranteed minimum income, accumulation and withdrawal benefits on variable annuities (1) and secondary guarantees on interest-sensitive life insurance and fixed annuities Interest rates used in establishing reserves range from 1.7% to 10.3% Withdrawal and surrender (1) In 2006, the Company disposed of its variable annuity business through a reinsurance agreement with Prudential. Contractholder funds activity for the years ended December 31 is as follows: ($ in thousands) 2016 2015 2014 Balance, beginning of year $ 3,185,887 $ 3,402,594 $ 3,670,557 Deposits 105,671 103,041 105,626 Interest credited 102,805 108,730 118,957 Benefits (122,109 ) (137,834 ) (145,889 ) Surrenders and partial withdrawals (172,856 ) (211,171 ) (279,835 ) Contract charges (73,866 ) (72,575 ) (71,332 ) Net transfers from separate accounts 133 252 143 Other adjustments (6,932 ) (7,150 ) 4,367 Balance, end of year $ 3,018,733 $ 3,185,887 $ 3,402,594 The Company offered various guarantees to variable annuity contractholders. In 2006, the Company disposed of its variable annuity business through a reinsurance agreement with Prudential. Liabilities for variable contract guarantees related to death benefits are included in the reserve for life-contingent contract benefits and the liabilities related to the income, withdrawal and accumulation benefits are included in contractholder funds. All liabilities for variable contract guarantees are reported on a gross basis on the balance sheet with a corresponding reinsurance recoverable asset. Absent any contract provision wherein the Company guarantees either a minimum return or account value upon death, a specified contract anniversary date, partial withdrawal or annuitization, variable annuity and variable life insurance contractholders bear the investment risk that the separate accounts’ funds may not meet their stated investment objectives. The account balances of variable annuities contracts’ separate accounts with guarantees included $233.8 million and $264.5 million of equity, fixed income and balanced mutual funds and $39.8 million and $36.8 million of money market mutual funds as of December 31, 2016 and 2015, respectively. The table below presents information regarding the Company’s variable annuity contracts with guarantees. The Company’s variable annuity contracts may offer more than one type of guarantee in each contract; therefore, the sum of amounts listed exceeds the total account balances of variable annuity contracts’ separate accounts with guarantees. ($ in millions) December 31, 2016 2015 In the event of death Separate account value $ 273.6 $ 301.3 Net amount at risk (1) $ 8.5 $ 15.3 Average attained age of contractholders 66 years 66 years At annuitization (includes income benefit guarantees) Separate account value $ 19.8 $ 22.9 Net amount at risk (2) $ 2.5 $ 2.5 Weighted average waiting period until annuitization options available None None For cumulative periodic withdrawals Separate account value $ 18.6 $ 19.6 Net amount at risk (3) $ 0.4 $ 0.3 Accumulation at specified dates Separate account value $ 65.3 $ 83.4 Net amount at risk (4) $ 1.4 $ 2.4 Weighted average waiting period until guarantee date 2 years 3 years (1) Defined as the estimated current guaranteed minimum death benefit in excess of the current account balance as of the balance sheet date. (2) Defined as the estimated present value of the guaranteed minimum annuity payments in excess of the current account balance. (3) Defined as the estimated current guaranteed minimum withdrawal balance (initial deposit) in excess of the current account balance as of the balance sheet date. (4) Defined as the estimated present value of the guaranteed minimum accumulation balance in excess of the current account balance. The liability for death and income benefit guarantees is equal to a benefit ratio multiplied by the cumulative contract charges earned, plus accrued interest less contract excess guarantee benefit payments. The benefit ratio is calculated as the estimated present value of all expected contract excess guarantee benefits divided by the present value of all expected contract charges. The establishment of reserves for these guarantees requires the projection of future fund values, mortality, persistency and customer benefit utilization rates. These assumptions are periodically reviewed and updated. For guarantees related to death benefits, benefits represent the projected excess guaranteed minimum death benefit payments. For guarantees related to income benefits, benefits represent the present value of the minimum guaranteed annuitization benefits in excess of the projected account balance at the time of annuitization. Projected benefits and contract charges used in determining the liability for certain guarantees are developed using models and stochastic scenarios that are also used in the development of estimated expected gross profits. Underlying assumptions for the liability related to income benefits include assumed future annuitization elections based on factors such as the extent of benefit to the potential annuitant, eligibility conditions and the annuitant’s attained age. The liability for guarantees is re-evaluated Guarantees related to withdrawal and accumulation benefits are considered to be derivative financial instruments; therefore, the liability for these benefits is established based on its fair value.

Reinsurance	9. Reinsurance The Company reinsures certain of its risks to unaffiliated reinsurers and ALIC under yearly renewable term, coinsurance and modified coinsurance agreements. These agreements result in a passing of the agreed-upon percentage of risk to the reinsurer in exchange for negotiated reinsurance premium payments. Modified coinsurance is similar to coinsurance, except that the cash and investments that support the liability for contract benefits are not transferred to the assuming company and settlements are made on a net basis between the companies. As of December 31, 2016 and 2015, for certain term life insurance policies, the Company ceded up to 90% of the mortality risk depending on the year of policy issuance. Further, the Company cedes the mortality risk associated with coverage in excess of $2 million per life to ALIC. Prior to July 1, 2013, the Company ceded mortality risk in excess of $250 thousand per life to ALIC. In addition, the Company has used reinsurance to effect the disposition of certain blocks of business. The Company had reinsurance recoverables of $179.9 million and $185.4 million as of December 31, 2016 and 2015, respectively, due from Prudential related to the disposal of its variable annuity business that was effected through reinsurance agreements. In 2016, premiums and contract charges of $5.8 million, contract benefits of $(0.4) million, interest credited to contractholder funds of $4.8 million, and operating costs and expenses of $1.1 million were ceded to Prudential. In 2015, premiums and contract charges of $7.1 million, contract benefits of $1.4 million, interest credited to contractholder funds of $4.5 million, and operating costs and expenses of $1.1 million were ceded to Prudential. In 2014, premiums and contract charges of $8.2 million, contract benefits of $1.4 million, interest credited to contractholder funds of $5.2 million, and operating costs and expenses of $1.3 million were ceded to Prudential. In addition, as of December 31, 2016 and 2015 the Company had reinsurance recoverables of $162 thousand and $114 thousand, respectively, due from a subsidiary of Citigroup (Triton Insurance Company) in connection with the disposition of the direct response distribution business in 2003. As of December 31, 2016, the gross life insurance in force was $41.53 billion of which $544.1 million and $8.76 billion was ceded to affiliated and unaffiliated reinsurers, respectively.

Guarantees and Contingent Liabi

Guarantees and Contingent Liabilities	12 Months Ended

Guarantees and Contingent Liabilities	11. Guarantees and Contingent Liabilities Guaranty funds Under state insurance guaranty fund laws, insurers doing business in a state can be assessed, up to prescribed limits, for certain obligations of insolvent insurance companies to policyholders and claimants. Amounts assessed to each company are typically related to its proportion of business written in each state. The Company’s policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile’s statutory definition of insolvency and the amount of the loss is reasonably estimable. In most states, the definition is met with a declaration of financial insolvency by a court of competent jurisdiction. In certain states there must also be a final order of liquidation. As of December 31, 2016 and 2015, the liability balance included in other liabilities and accrued expenses was $724 thousand and $750 thousand, respectively. The related premium tax offsets included in other assets were $3.6 million as of both December 31, 2016 and 2015. Guarantees In the normal course of business, the Company provides standard indemnifications to contractual counterparties in connection with numerous transactions, including acquisitions and divestitures. The types of indemnifications typically provided include indemnifications for breaches of representations and warranties, taxes and certain other liabilities, such as third party lawsuits. The indemnification clauses are often standard contractual terms and are entered into in the normal course of business based on an assessment that the risk of loss would be remote. The terms of the indemnifications vary in duration and nature. In many cases, the maximum obligation is not explicitly stated and the contingencies triggering the obligation to indemnify have not occurred and are not expected to occur. Consequently, the maximum amount of the obligation under such indemnifications is not determinable. Historically, the Company has not made any material payments pursuant to these obligations. Related to the disposal through reinsurance of the Company’s variable annuity business to Prudential in 2006, the Company, ALIC and the Corporation have agreed to indemnify Prudential for certain pre-closing The aggregate liability balance related to all guarantees was not material as of December 31, 2016. Regulation and Compliance The Company is subject to extensive laws, regulations and regulatory actions. From time to time, regulatory authorities or legislative bodies seek to impose additional regulations regarding agent and broker compensation, regulate the nature of and amount of investments, impose fines and penalties for unintended errors or mistakes, and otherwise expand overall regulation of insurance products and the insurance industry. In addition, the Company is subject to laws and regulations administered and enforced by federal agencies and other organizations, including but not limited to the Securities and Exchange Commission, the Financial Industry Regulatory Authority, the Department of Labor, and the U.S. Department of Justice. The Company has established procedures and policies to facilitate compliance with laws and regulations, to foster prudent business operations, and to support financial reporting. The Company routinely reviews its practices to validate compliance with laws and regulations and with internal procedures and policies. As a result of these reviews, from time to time the Company may decide to modify some of its procedures and policies. Such modifications, and the reviews that led to them, may be accompanied by payments being made and costs being incurred. The ultimate changes and eventual effects of these actions on the Company’s business, if any, are uncertain.

Income Taxes	12. Income Taxes The Company joins with the Corporation and its other subsidiaries (the “Allstate Group”) in the filing of a consolidated federal income tax return and is party to a federal income tax allocation agreement (the “Allstate Tax Sharing Agreement”). Under the Allstate Tax Sharing Agreement, the Company pays to or receives from the Corporation the amount, if any, by which the Allstate Group’s federal income tax liability is affected by virtue of inclusion of the Company in the consolidated federal income tax return. Effectively, this results in the Company’s annual income tax provision being computed, with adjustments, as if the Company filed a separate return. The Internal Revenue Service (“IRS”) is currently examining the Allstate Group’s 2013 and 2014 federal income tax returns. The Allstate Group’s tax years prior to 2013 have been examined by the IRS and the statute of limitations has expired on those years. Any adjustments that may result from IRS examinations of the Allstate Group’s tax returns are not expected to have a material effect on the results of operations, cash flows or financial position of the Company. The Company had no liability for unrecognized tax benefits as of December 31, 2016, 2015 or 2014, and believes it is reasonably possible that the liability balance will not significantly increase within the next twelve months. No amounts have been accrued for interest or penalties. The components of the deferred income tax assets and liabilities as of December 31 are as follows: ($ in thousands) 2016 2015 Deferred assets Unrealized foreign currency translation adjustments $ 378 $ 991 Accrued liabilities 41 41 Other assets 55 8 Total deferred assets 474 1,040 Deferred liabilities Unrealized net capital gains (98,184 ) (84,963 ) Difference in tax bases of investments (77,505 ) (63,767 ) Life and annuity reserves (40,491 ) (36,021 ) DAC (29,807 ) (29,090 ) Other liabilities (2,139 ) (2,703 ) Total deferred liabilities (248,126 ) (216,544 ) Net deferred liability $ (247,652 ) $ (215,504 ) Although realization is not assured, management believes it is more likely than not that the deferred tax assets will be realized based on the Company’s assessment that the deductions ultimately recognized for tax purposes will be fully utilized. The components of income tax expense for the years ended December 31 are as follows: ($ in thousands) 2016 2015 2014 Current $ 9,694 $ 31,062 $ 38,729 Deferred 18,314 9,915 30,260 Total income tax expense $ 28,008 $ 40,977 $ 68,989 The Company paid income taxes of $9.6 million, $53.3 million and $21.1 million in 2016, 2015 and 2014, respectively.

Statutory Financial Information

Statutory Financial Information and Dividend Limitations	12 Months Ended

Statutory Financial Information and Dividend Limitations	13. Statutory Financial Information and Dividend Limitations The Company prepares its statutory-basis financial statements in conformity with accounting practices prescribed or permitted by the State of New York. Prescribed statutory accounting practices include a variety of publications of the National Association of Insurance (“NAIC”), as well as state laws, regulations and general administrative rules. Permitted statutory accounting practices encompass all accounting practices not so prescribed. The State of New York requires insurance companies domiciled in its state to prepare statutory-basis financial statements in conformity with the NAIC Accounting Practices and Procedures Manual, subject to any deviations prescribed or permitted by the State of New York Insurance Superintendent. Statutory accounting practices differ from GAAP primarily since they require charging policy acquisition and certain sales inducement costs to expense as incurred, establishing life insurance reserves based on different actuarial assumptions, and valuing certain investments and establishing deferred taxes on a different basis. Statutory net (loss) income was $(12.6) million, $(63.9) million and $31.3 million in 2016, 2015 and 2014, respectively. Statutory capital and surplus was $520.1 million and $507.6 million as of December 31, 2016 and 2015, respectively. Dividend Limitations The ability of the Company to pay dividends is dependent on business conditions, income, cash requirements and other relevant factors. The payment of shareholder dividends by the Company without the prior approval of the New York Department of Financial Services (“NYDFS”) is limited to formula amounts based on capital and surplus and net gain from operations excluding realized capital gains and losses, determined in conformity with statutory accounting practices, as well as the timing and amount of dividends paid in the preceding twelve months. The Company did not pay any dividends in 2016. The maximum amount of dividends the Company will be able to pay without prior NYDFS approval at a given point in time during 2017 is $52.0 million. Any dividend must be paid out of unassigned surplus excluding unrealized appreciation from investments, which totaled $316.2 million as of December 31, 2016, and cannot result in capital and surplus being less than the minimum amount required by law. Under state insurance laws, insurance companies are required to maintain paid up capital of not less than the minimum capital requirement applicable to the types of insurance they are authorized to write. Insurance companies are also subject to risk-based capital (“RBC”) requirements adopted by state insurance regulators. A company’s “authorized control level RBC” is calculated using various factors applied to certain financial balances and activity. Companies that do not maintain adjusted statutory capital and surplus at a level in excess of the company action level RBC, which is two times authorized control level RBC, are required to take specified actions. Company action level RBC is significantly in excess of the minimum capital requirements. Total adjusted statutory capital and surplus and authorized control level RBC of the Company were $628.3 million and $72.3 million, respectively, as of December 31, 2016.

Investments	Investments Fixed income securities include bonds, asset-backed securities (“ABS”), residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”) and redeemable preferred stocks. Fixed income securities, which may be sold prior to their contractual maturity, are designated as available for sale and are carried at fair value. The difference between amortized cost and fair value, net of deferred income taxes and related deferred policy acquisition costs (“DAC”), deferred sales inducement costs (“DSI”) and reserves for life-contingent contract benefits, is reflected as a component of accumulated other comprehensive income. Cash received from calls and make-whole payments is reflected as a component of proceeds from sales and cash received from maturities and pay-downs Mortgage loans are carried at unpaid principal balances, net of unamortized premium or discount and valuation allowances. Valuation allowances are established for impaired loans when it is probable that contractual principal and interest will not be collected. Equity securities primarily include common stocks, exchange traded funds, non-redeemable Investments in limited partnership interests include interests in private equity funds and co-investments, Short-term investments, including commercial paper, U.S. Treasury bills, money market funds and other short-term investments, are carried at fair value. Policy loans are carried at unpaid principal balances. Other investments consist of derivatives. Derivatives are carried at fair value. Investment income primarily consists of interest, dividends, income from limited partnership interests, and income from certain derivative transactions. Interest is recognized on an accrual basis using the effective yield method and dividends are recorded at the ex-dividend pay-downs, Realized capital gains and losses include gains and losses on investment sales, write-downs in value due to other-than-temporary declines in fair value, adjustments to valuation allowances on mortgage loans, periodic changes in fair value and settlements of certain derivatives including hedge ineffectiveness and valuation changes in public securities held in certain limited partnerships. Realized capital gains and losses on investment sales are determined on a specific identification basis.
Derivative and embedded derivative financial instruments	Derivative and embedded derivative financial instruments Derivative financial instruments include equity futures, options, interest rate caps, foreign currency forwards and a reinvestment related risk transfer reinsurance agreement with ALIC that meets the accounting definition of a derivative (see Note 4). Derivatives required to be separated from the host instrument and accounted for as derivative financial instruments (“subject to bifurcation”) are embedded in equity-indexed life contracts and reinsured variable annuity contracts. All derivatives are accounted for on a fair value basis and reported as other investments, other assets, other liabilities and accrued expenses or contractholder funds. The income statement effects of derivatives, including fair value gains and losses and accrued periodic settlements, are reported either in realized capital gains and losses or in a single line item together with the results of the associated asset or liability for which risks are being managed. Embedded derivative instruments subject to bifurcation are also accounted for on a fair value basis and are reported together with the host contract. The change in fair value of derivatives embedded in life and annuity product contracts and subject to bifurcation is reported in contract benefits or interest credited to contractholder funds. Cash flows from embedded derivatives subject to bifurcation are reported consistently with the host contracts within the Statements of Cash Flows. Cash flows from other derivatives are reported in cash flows from investing activities within the Statements of Cash Flows.
Securities loaned	Securities loaned The Company’s business activities include securities lending transactions, which are used primarily to generate net investment income. The proceeds received in conjunction with securities lending transactions are reinvested in short-term investments. These transactions are short-term in nature, usually 30 days or less. The Company receives cash collateral for securities loaned in an amount generally equal to 102% of the fair value of securities and records the related obligations to return the collateral in other liabilities and accrued expenses. The carrying value of these obligations approximates fair value because of their relatively short-term nature. The Company monitors the market value of securities loaned on a daily basis and obtains additional collateral as necessary under the terms of the agreements to mitigate counterparty credit risk. The Company maintains the right and ability to repossess the securities loaned on short notice.
Recognition of Premium Revenues and Contract Charges, and Related Benefits and Interest Credited	Recognition of premium revenues and contract charges, and related benefits and interest credited Traditional life insurance products consist principally of products with fixed and guaranteed premiums and benefits, primarily term and whole life insurance products. Voluntary accident and health insurance products are expected to remain in force for an extended period and therefore are primarily classified as long-duration contracts. Premiums from these products are recognized as revenue when due from policyholders. Benefits are reflected in contract benefits and recognized over the life of the policy in relation to premiums. Immediate annuities with life contingencies, including certain structured settlement annuities, provide insurance protection over a period that extends beyond the period during which premiums are collected. Premiums from these products are recognized as revenue when received at the inception of the contract. Benefits and expenses are recognized in relation to premiums. Profits from these policies come primarily from investment income, which is recognized over the life of the contract. Interest-sensitive life contracts, such as universal life and single premium life, are insurance contracts whose terms are not fixed and guaranteed. The terms that may be changed include premiums paid by the contractholder, interest credited to the contractholder account balance and contract charges assessed against the contractholder account balance. Premiums from these contracts are reported as contractholder fund deposits. Contract charges consist of fees assessed against the contractholder account balance for the cost of insurance (mortality risk), contract administration and surrender of the contract prior to contractually specified dates. These contract charges are recognized as revenue when assessed against the contractholder account balance. Contract benefits include life-contingent benefit payments in excess of the contractholder account balance. Contracts that do not subject the Company to significant risk arising from mortality or morbidity are referred to as investment contracts. Fixed annuities, including market value adjusted annuities and immediate annuities without life contingencies, are considered investment contracts. Consideration received for such contracts is reported as contractholder fund deposits. Contract charges for investment contracts consist of fees assessed against the contractholder account balance for maintenance, administration and surrender of the contract prior to contractually specified dates, and are recognized when assessed against the contractholder account balance. Interest credited to contractholder funds represents interest accrued or paid on interest-sensitive life and investment contracts. Crediting rates for certain fixed annuities and interest-sensitive life contracts are adjusted periodically by the Company to reflect current market conditions subject to contractually guaranteed minimum rates. Crediting rates for indexed life contracts are generally based on an equity index, such as the Standard & Poor’s 500 Index (“S&P 500”). Interest credited also includes amortization of DSI expenses. DSI is amortized into interest credited using the same method used to amortize DAC. Contract charges for variable life and variable annuity products consist of fees assessed against the contractholder account balances for contract maintenance, administration, mortality, expense and surrender of the contract prior to contractually specified dates. Contract benefits incurred for variable annuity products include guaranteed minimum death, income, withdrawal and accumulation benefits. All of the Company’s variable annuity business is ceded through reinsurance agreements and the contract charges and contract benefits related thereto are reported net of reinsurance ceded.
Deferred Policy Acquisition and Sales Inducement Costs	Deferred policy acquisition and sales inducement costs Costs that are related directly to the successful acquisition of new or renewal life insurance and investment contracts are deferred and recorded as DAC. These costs are principally agents’ and brokers’ remuneration and certain underwriting expenses. DSI costs, which are deferred and recorded as other assets, relate to sales inducements offered on sales to new customers, principally on fixed annuity and interest-sensitive life contracts. These sales inducements are primarily in the form of additional credits to the customer’s account balance or enhancements to interest credited for a specified period which are in excess of the rates currently being credited to similar contracts without sales inducements. All other acquisition costs are expensed as incurred and included in operating costs and expenses. Amortization of DAC is included in amortization of deferred policy acquisition costs and is described in more detail below. DSI is amortized into income using the same methodology and assumptions as DAC and is included in interest credited to contractholder funds. For traditional life and voluntary accident and health insurance, DAC is amortized over the premium paying period of the related policies in proportion to the estimated revenues on such business. Assumptions used in the amortization of DAC and reserve calculations are established at the time the policy is issued and are generally not revised during the life of the policy. Any deviations from projected business in force resulting from actual policy terminations differing from expected levels and any estimated premium deficiencies may result in a change to the rate of amortization in the period such events occur. Generally, the amortization periods for these policies approximates the estimated lives of the policies. The Company periodically reviews the recoverability of DAC for these policies on an aggregate basis using actual experience. The Company aggregates traditional life insurance products and immediate annuities with life contingencies in one analysis, and voluntary accident and health insurance in a separate analysis. If actual experience is significantly adverse compared to the original assumptions and a premium deficiency is determined to exist, any remaining unamortized DAC balance would be expensed to the extent not recoverable and the establishment of a premium deficiency reserve may be required. For interest-sensitive life insurance and fixed annuities, DAC and DSI are amortized in proportion to the incidence of the total present value of gross profits, which includes both actual historical gross profits (“AGP”) and estimated future gross profits (“EGP”) expected to be earned over the estimated lives of the contracts. The amortization is net of interest on the prior period DAC balance using rates established at the inception of the contracts. Actual amortization periods generally range from 15-30 10-20 5-10 AGP and EGP primarily consist of the following components: contract charges for the cost of insurance less mortality costs and other benefits; investment income and realized capital gains and losses less interest credited; and surrender and other contract charges less maintenance expenses. The principal assumptions for determining the amount of EGP are mortality, persistency, expenses, investment returns, including capital gains and losses on assets supporting contract liabilities, interest crediting rates to contractholders, and the effects of any hedges. For products whose supporting investments are exposed to capital losses in excess of the Company’s expectations which may cause periodic AGP to become temporarily negative, EGP and AGP utilized in DAC and DSI amortization may be modified to exclude the excess capital losses. The Company performs quarterly reviews of DAC and DSI recoverability for interest-sensitive life and fixed annuity contracts in the aggregate using current assumptions. If a change in the amount of EGP is significant, it could result in the unamortized DAC or DSI not being recoverable, resulting in a charge which is included as a component of amortization of deferred policy acquisition costs or interest credited to contractholder funds, respectively. The DAC and DSI balances presented include adjustments to reflect the amount by which the amortization of DAC and DSI would increase or decrease if the unrealized capital gains or losses in the respective product investment portfolios were actually realized. The adjustments are recorded net of tax in accumulated other comprehensive income. DAC, DSI and deferred income taxes determined on unrealized capital gains and losses and reported in accumulated other comprehensive income recognize the impact on shareholder’s equity consistently with the amounts that would be recognized in the income statement on realized capital gains and losses. Customers of the Company may exchange one insurance policy or investment contract for another offered by the Company, or make modifications to an existing investment or life contract issued by the Company. These transactions are identified as internal replacements for accounting purposes. Internal replacement transactions determined to result in replacement contracts that are substantially unchanged from the replaced contracts are accounted for as continuations of the replaced contracts. Unamortized DAC and DSI related to the replaced contracts continue to be deferred and amortized in connection with the replacement contracts. For interest-sensitive life and investment contracts, the EGP of the replacement contracts are treated as a revision to the EGP of the replaced contracts in the determination of amortization of DAC and DSI. For traditional life insurance policies, any changes to unamortized DAC that result from replacement contracts are treated as prospective revisions. Any costs associated with the issuance of replacement contracts are characterized as maintenance costs and expensed as incurred. Internal replacement transactions determined to result in a substantial change to the replaced contracts are accounted for as an extinguishment of the replaced contracts, and any unamortized DAC and DSI related to the replaced contracts are eliminated with a corresponding charge to amortization of deferred policy acquisition costs or interest credited to contractholder funds, respectively.
Reinsurance	Reinsurance In the normal course of business, the Company seeks to limit aggregate and single exposure to losses on large risks by purchasing reinsurance. The Company has also used reinsurance to effect the disposition of certain blocks of business. The amounts reported as reinsurance recoverables include amounts billed to reinsurers on losses paid as well as estimates of amounts expected to be recovered from reinsurers on insurance liabilities and contractholder funds that have not yet been paid. Reinsurance recoverables on unpaid losses are estimated based upon assumptions consistent with those used in establishing the liabilities related to the underlying reinsured contracts. Insurance liabilities are reported gross of reinsurance recoverables. Reinsurance premiums are generally reflected in income in a manner consistent with the recognition of premiums on the reinsured contracts. Reinsurance does not extinguish the Company’s primary liability under the policies written. Therefore, the Company regularly evaluates the financial condition of its reinsurers and establishes allowances for uncollectible reinsurance as appropriate. The Company has a reinsurance treaty with ALIC through which it primarily cedes reinvestment related risk on its structured settlement annuities. The terms of the treaty meet the accounting definition of a derivative. Accordingly, the treaty is recorded in the Statement of Financial Position at fair value. Changes in the fair value of the treaty and premiums paid to ALIC are recognized in realized capital gains and losses.
Income taxes	Income taxes The income tax provision is calculated under the liability method. Deferred tax assets and liabilities are recorded based on the difference between the financial statement and tax bases of assets and liabilities at the enacted tax rates. The principal assets and liabilities giving rise to such differences are unrealized capital gains and losses, differences in tax bases of invested assets, insurance reserves and DAC. A deferred tax asset valuation allowance is established when there is uncertainty that such assets will be realized.
Reserve for life-contingent contract benefits	Reserve for life-contingent contract benefits The reserve for life-contingent contract benefits payable under insurance policies, including traditional life insurance, life-contingent immediate annuities and voluntary accident and health insurance products, is computed on the basis of long-term actuarial assumptions of future investment yields, mortality, morbidity, policy terminations and expenses. These assumptions, which for traditional life insurance are applied using the net level premium method, include provisions for adverse deviation and generally vary by characteristics such as type of coverage, year of issue and policy duration. The assumptions are established at the time the policy is issued and are generally not changed during the life of the policy. The Company periodically reviews the adequacy of reserves for these policies on an aggregate basis using actual experience. If actual experience is significantly adverse compared to the original assumptions and a premium deficiency is determined to exist, any remaining unamortized DAC balance would be expensed to the extent not recoverable and the establishment of a premium deficiency reserve may be required. The Company also reviews these policies on an aggregate basis for circumstances where projected profits would be recognized in early years followed by projected losses in later years. If this circumstance exists, the Company will accrue a liability, during the period of profits, to offset the losses at such time as the future losses are expected to commence using a method updated prospectively over time. To the extent that unrealized gains on fixed income securities would result in a premium deficiency if those gains were realized, the related increase in reserves for certain immediate annuities with life contingencies is recorded net of tax as a reduction of unrealized net capital gains included in accumulated other comprehensive income.
Contractholder funds	Contractholder funds Contractholder funds represent interest-bearing liabilities arising from the sale of products such as interest-sensitive life insurance and fixed annuities. Contractholder funds primarily comprise cumulative deposits received and interest credited to the contractholder less cumulative contract benefits, surrenders, withdrawals and contract charges for mortality or administrative expenses. Contractholder funds also include reserves for secondary guarantees on interest-sensitive life insurance and certain fixed annuity contracts and reserves for certain guarantees on reinsured variable annuity contracts.
Separate accounts	Separate accounts Separate accounts assets are carried at fair value. The assets of the separate accounts are legally segregated and available only to settle separate account contract obligations. Separate accounts liabilities represent the contractholders’ claims to the related assets and are carried at an amount equal to the separate accounts assets. Investment income and realized capital gains and losses of the separate accounts accrue directly to the contractholders and therefore are not included in the Company’s Statements of Operations and Comprehensive Income. Deposits to and surrenders and withdrawals from the separate accounts are reflected in separate accounts liabilities and are not included in cash flows. Absent any contract provision wherein the Company provides a guarantee, variable annuity and variable life insurance contractholders bear the investment risk that the separate accounts’ funds may not meet their stated investment objectives. All of the Company’s variable annuity business was reinsured beginning in 2006.
Off-balance sheet financial instruments	Off-balance Commitments to invest, commitments to purchase private placement securities and financial guarantees have off-balance
Adopted and pending accounting standards	Adopted accounting standard Amendments to the Consolidation Analysis In February 2015, the Financial Accounting Standards Board (“FASB”) issued guidance affecting the consolidation evaluation for limited partnerships and similar entities, fees paid to a decision maker or service provider, and variable interests in a variable interest entity held by related parties of the reporting enterprise. The adoption of this guidance as of January 1, 2016 did not have a material impact on the Company’s results of operations or financial position. Pending accounting standards Recognition and Measurement of Financial Assets and Financial Liabilities In January 2016, the FASB issued guidance requiring equity investments, including equity securities and limited partnership interests, that are not accounted for under the equity method of accounting or result in consolidation to be measured at fair value with changes in fair value recognized in net income. Equity investments without readily determinable fair values may be measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. When a qualitative assessment of equity investments without readily determinable fair values indicates that impairment exists, the carrying value is required to be adjusted to fair value, if lower. The guidance clarifies that an entity should evaluate the realizability of a deferred tax asset related to available-for-sale pre-tax pre-tax, Transition to Equity Method Accounting In March 2016, the FASB issued guidance amending the accounting requirements for transitioning to the equity method of accounting (“EMA”), including a transition from the cost method. The guidance requires the cost of acquiring an additional interest in an investee to be added to the existing carrying value to establish the initial basis of the EMA investment. Under the new guidance, no retroactive adjustment is required when an investment initially qualifies for EMA treatment. The guidance is effective for annual periods beginning after December 15, 2016, and is to be applied prospectively. The guidance will principally affect the future accounting for investments that qualify for EMA after application of the cost method of accounting. The Company is in the process of evaluating the impact of adoption, which is not expected to be material to the Company’s results of operations or financial position. Measurement of Credit Losses on Financial Instruments In June 2016, the FASB issued guidance which revises the credit loss recognition criteria for certain financial assets measured at amortized cost. The new guidance replaces the existing incurred loss recognition model with an expected loss recognition model. The objective of the expected credit loss model is for the reporting entity to recognize its estimate of expected credit losses for affected financial assets in a valuation allowance deducted from the amortized cost basis of the related financial assets that results in presenting the net carrying value of the financial assets at the amount expected to be collected. The reporting entity must consider all available relevant information when estimating expected credit losses, including details about past events, current conditions, and reasonable and supportable forecasts over the contractual life of an asset. Financial assets may be evaluated individually or on a pooled basis when they share similar risk characteristics. The measurement of credit losses for available-for-sale

[1]	Unrealized net capital gains and losses for limited partnership interests represent the Company's share of EMA limited partnerships' other comprehensive income. Fair value and gross unrealized gains and losses are not applicable.
[2]	The insurance reserves adjustment represents the amount by which the reserve balance would increase if the net unrealized gains in the applicable product portfolios were realized and reinvested at current lower interest rates, resulting in a premium deficiency. Although the Company evaluates premium deficiencies on the combined performance of life insurance and immediate annuities with life contingencies, the adjustment primarily relates to structured settlement annuities with life contingencies, in addition to certain payout annuities with life contingencies.
[3]	The DAC and DSI adjustment balance represents the amount by which the amortization of DAC and DSI would increase or decrease if the unrealized gains or losses in the respective product portfolios were realized.
