Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2017
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies (a) Basis of Presentation The Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). (b) Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect reported amounts of assets and liabilities, including reporting or disclosure of contingent assets and liabilities as of December 31, 2017 and 2016 , and the reported amounts of revenues and expenses during the reporting period. Future events, including changes in mortality, morbidity, interest rates, capital markets, and asset valuations could cause actual results to differ from the estimates used within the Financial Statements. Such changes in estimates are recorded in the period they are determined. (c) Investment Products and Universal Life Business Investment products consist primarily of fixed and variable annuity products. Premium receipts are reported as deposits to the contractholders’ accounts or an establishment of future policy benefit reserves. Premiums and policy fees, net in the Statements of Operations represent asset fees, cost of insurance charges, administrative fees, charges for guarantees on investment products, and surrender charges for investment products and universal life insurance, all of which is net of reinsurance. These fees have been earned and assessed against contractholders on a daily or monthly basis throughout the contract period and are recognized as revenue when assessed and earned. Amounts assessed that represent compensation to the Company for services to be provided in future periods are not earned in the period assessed. Such amounts are reported as unearned revenue, which include unearned revenue reserves (URR), and are recognized in operations over the period benefited using the same assumptions and factors used to amortize capitalized acquisition costs. Unearned revenue is reported in Unearned premiums on the Balance Sheets. Surrender charges are recognized upon surrender of a contract in accordance with contractual terms. Derivatives embedded in fixed-indexed, variable, and certain life products are recorded at fair value and changes in value are included in Change in fair value of annuity and life embedded derivatives in the Statements of Operations. Benefits consist of interest credited to contractholders’ accounts and claims incurred in excess of the contractholders’ account balance, net of reinsurance, and are included in Net interest credited to account values and Policyholder benefits, net of recoveries, respectively, within the Statements of Operations. The Company offers a variable-indexed annuity product that combines a separate account option with a general account option that is similar to a fixed-indexed annuity. The Company has elected the fair value option to account for the entire insurance contract liability and the variable investment option assets in the separate account. The insurance contracts’ reserves are reported in Account balances and future policy benefit reserves and the variable investment option assets within the separate account are reported in Equity securities, trading on the Balance Sheets. Assets backing the general account are primarily reported in Fixed-maturity securities, available-for-sale on the Balance Sheets. Electing the fair value option for an insurance contract liability requires that the Company account for that liability as a financial instrument at fair value through profit and loss and also requires that acquisition costs be recognized immediately in expense. See note 6 for further details regarding the valuation methodology of the variable-indexed annuity product. (d) Life and Accident and Health Insurance Premiums on traditional life products are recognized as revenue over the premium-paying periods of the contracts when due from contractholders. Premium revenue generally exceeds expected policy benefits in the early years of the contracts and a reserve liability is established for costs and benefits that are expected to be paid in the later years of the contracts. Accident and health premiums are recognized as earned on a pro rata basis over the risk coverage periods. Benefits and expenses are recognized as incurred. (e) Investments Fixed-Maturity Securities and Equity Securities The Company has portfolios of fixed-maturity securities classified as “available-for-sale.” Accordingly, these securities are carried at fair value, and related unrealized gains and losses are credited or charged directly to accumulated other comprehensive income (AOCI) in stockholder’s equity, net of tax and related shadow adjustments. The adjustments to deferred acquisition costs (DAC) and deferred sale inducements (DSI) represent the change in amortization that would have been required as a charge or credit to operations had such unrealized amounts been realized. The adjustment to reserves represents the increase or decrease in the reserve balance that would have been required as a charge or credit to operations had such unrealized amounts been realized. The Company has a portfolio of equity securities classified as "trading". These securities are comprised of variable investment option assets within the separate account that relate directly to the variable-indexed annuity product. See note 2(c) for further detail regarding the presentation of this portfolio. These securities are carried at fair value, and related unrealized gains and losses are reflected in Change in fair value of assets and liabilities within the Statements of Operations. Dividends are accrued on the date they are declared. The Company has portfolios of structured securities which include mortgage-backed securities and other asset-backed securities. Mortgage-backed securities are presented separately while other asset-backed securities are included within 'Corporate securities' within the the Notes to the Financial Statements. Structured securities are amortized using, among other assumptions, anticipated prepayments. Prepayment assumptions for structured securities are obtained from various external sources or internal estimates. The Company believes these assumptions are consistent with those a market participant would use. The Company recognizes income using a constant effective yield method based on prepayment assumptions and the estimated economic life of the securities. For all structured securities , when actual prepayments differ significantly from anticipated prepayments, the effective yield is recalculated to reflect actual payments to date and anticipated future payments retrospectively. Any resulting adjustment is included in Interest and similar income, net in the Statements of Operations. The fair value of fixed-maturity securities and equity securities is obtained from third-party pricing sources whenever possible. Management completes its own independent price verification (IPV) process, which ensures security pricing is obtained from a third-party source other than the sources used by the Company's internal and external investment managers. The IPV process supports the reasonableness of price overrides and challenges by the internal and external investment managers and reviews pricing for appropriateness. Results of the IPV process are reviewed by the Company’s Pricing Committee. The Company reviews the available-for-sale fixed-maturity investment portfolios to determine whether or not declines in fair value are other-than-temporary. In addition, the Company continually evaluates average amortized cost, fair value, credit quality, extent and duration of the decline, market analysis, current events, recent price declines, changes in risk-free interest rates, and likelihood of recovery in a reasonable period of time. Based on this evaluation, the Company determines whether fixed-income securities are considered other-than-temporarily impaired. When the fair value of a fixed-maturity security is less than its amortized cost, the Company assesses whether or not (i) it has the intent to sell the security or (ii) it is more likely than not that the Company will be required to sell the security before its anticipated recovery. The Company evaluates these factors to determine whether the Company or any of its internal and external investment managers have the intent to sell a security or a group of securities. The Company performs a cash flow projection for several years into the future to determine whether cash needs would require the sale of any securities in an unrealized loss position. If either of these conditions are met, the Company must recognize an other-than-temporary impairment (OTTI) for the difference between the investment’s amortized cost basis and its fair value through earnings. For securities that do not meet the above criteria and the Company does not expect to recover a security’s amortized cost basis, the security is also considered other-than-temporarily impaired. For these securities, the Company separates the total impairment into the credit loss component and the amount of the loss related to other factors. The amount of the total impairment related to credit loss is considered an OTTI and is recognized in Realized investment (losses) gains, net in the Statements of Operations. The amount of the total impairment related to other factors is recognized in other comprehensive income (OCI), net of impacts to DAC, DSI, reserves, and deferred income taxes. For available-for-sale securities that have recognized an OTTI through earnings, if through subsequent evaluation there is a significant increase in the cash flow expected, the difference between the amortized cost basis and the discounted cash flows expected to be collected is accreted as interest income. Subsequent increases and decreases not related to additional credit losses in the fair value of available-for-sale securities are included in the Statements of Comprehensive Income (Loss). The Company evaluates whether a credit loss exists by considering primarily the following factors: (a) the length of time and extent to which the fair value has been less than the amortized cost of the security; (b) changes in the financial condition, credit rating, and near-term prospects of the issuer; (c) whether the issuer is current on contractually obligated interest and principal payments; (d) changes in the financial condition of the security’s underlying collateral, if any; and (e) the payment structure of the security . The Company uses a probability-weighted cash flow model for fixed-maturity securities to determine the credit loss amount. This measurement is a quantitative and qualitative process that incorporates information received from third-party sources along with certain internal assumptions and significant judgments regarding the future performance of the security. The Company’s probability-weighted cash flow model involves assumptions including, but not limited to, various performance indicators, such as historical and projected default and recovery rates, credit ratings, and current delinquency rates. The Company provides a supplemental disclosure within the Statements of Operations that presents the total OTTI losses recognized in earnings during the period. The supplemental disclosure excludes subsequent increases and decrease in the fair value of these securities. Impairments in the value of securities held by the Company considered to be other-than-temporary are recorded as a reduction of the cost of the security, and a corresponding realized loss is recognized in the Statements of Operations. The Company adjusts DAC and DSI for impairments on securities, as discussed in their respective sections of this note. Short-Term Securities Short-term securities are comprised of fixed-maturity securities with an original maturity of twelve months or less and greater than three months when purchased. Short-term securities are carried at amortized cost, which approximates fair value due to their short-term nature. Policy Loans Policy loans are supported by the underlying cash value of the policies. Policy loans are carried at unpaid principal balances plus accrued interest income on the Balance Sheets. Variable Interest Entities In the normal course of business, the Company enters into relationships with various entities that are deemed to be variable interest entities. A variable interest entity (VIE) is an entity that either (1) has equity investors that lack certain essential characteristics of a controlling financial interest (including the ability to control activities of the entity, the obligation to absorb the entity’s expected losses, and the right to receive the entity’s expected residual returns) or (2) lacks sufficient equity to finance its own activities without financial support provided by other entities, which in turn would be expected to absorb at least some of the expected losses of the VIE. The Company consolidates a VIE if it is determined to be the primary beneficiary. Those entities which do not meet the requirements to be a VIE are voting interest entities (VOEs). The Company consolidates a VOE if it holds a voting interest that is greater than 50%. (f) Derivatives The Company utilizes derivatives within certain actively managed investment portfolios. Within these portfolios, derivatives can be used for hedging, replication, and income generation only. The financial instruments are carried at fair value and the unrealized gains and losses are reflected in Change in fair value of assets and liabilities in the Statements of Operations. Futures and Options Contracts The Company provides benefits through certain life and annuity products which are linked to the fluctuation of various market indices, and certain variable annuity contracts that provide minimum guaranteed benefits. The Company has analyzed the characteristics of these benefits and has entered into over-the-counter (OTC) option contracts and exchange-traded futures contracts tied to an underlying index with similar characteristics with the objective to economically hedge these benefits. Management monitors in-force amounts and option and futures contract values to ensure satisfactory matching and to identify unsatisfactory mismatches. If actual persistency deviated, management would purchase or sell option and futures contracts as deemed appropriate or take other actions. The OTC option contracts are reported at fair value in Derivative assets and Derivative liabilities on the Balance Sheets. The fair value of the OTC options is derived internally and deemed by management to be reasonable via performing an IPV process. The process of deriving internal derivative prices requires the Company to calibrate Monte Carlo scenarios to actual market information. The calibrated scenarios are applied to derivative cash flow models to calculate fair value prices for the derivatives. Changes in unrealized gains and losses on the OTC option contracts and incremental gains and losses from expiring contracts are recorded within Change in fair value of assets and liabilities in the Statements of Operations. Futures contracts do not require an initial cash outlay, and the Company has agreed to daily net settlement based on movements of the representative index. Therefore, no asset or liability is recorded on the Balance Sheets. Gains and/or losses on futures contracts are included in Change in fair value of assets and liabilities in the Statements of Operations. Interest Rate Swaps and Total Return Swaps The Company utilizes interest rate swaps (IRS) and total return swaps (TRS) also to economically hedge market risks embedded in certain annuities . The IRS and TRS are reported at fair value in Derivative assets and Derivative liabilities on the Balance Sheets . The fair value of the IRS are derived using a third-party vendor software program and deemed by management to be reasonable. Centrally cleared IRS fair values are obtained from the exchange on which they were traded. The fair value of the TRS is based on counterparty pricing and deemed by management to be reasonable. The unrealized gains and losses as well as investment income and expenses on these derivatives are recorded in Change in fair value of assets and liabilities in the Statements of Operations. (g) Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits, short-term government money market funds, overnight commercial paper, and highly liquid debt instruments purchased with an original maturity of three months or less. Due to the short-term nature of these investments, the carrying value is deemed to approximate fair value. (h) Receivables Receivable balances (contractual amount less allowance for doubtful accounts) are based on pertinent information available to management as of year-end, including the financial condition and creditworthiness of the parties underlying the receivables. Receivable balances are monitored and the allowance for doubtful accounts is maintained based on the nature of the receivables, and the Company’s assessment of the ability to collect . The allowance is estimated by aging the balances due from individual parties and generally setting up an allowance for any balances that are more than 90 days old. (i) Reinsurance The Company cedes business with other insurers. Reinsurance premium and benefits paid or provided are accounted for in a manner consistent with the basis used in accounting for original policies issued and the terms of the reinsurance contracts and are included in Premiums and policy fees, net, and Policyholder benefits, net of recoveries, respectively, in the Statements of Operations. Insurance liabilities are reported before the effects of reinsurance. Account balances and future policy benefit reserves and policy and contract claims covered under reinsurance contracts are recorded in Reinsurance and investment contract recoverables on the Balance Sheets. Amounts paid or deemed to have been paid for claims covered by reinsurance contracts are recorded as Receivables on the Balance Sheets. Reinsurance and investment contract recoverables are recognized in a manner consistent with the liabilities related to the underlying reinsured contracts. Amounts due to other insurers on assumed business are recorded as a reinsurance payable, and are included in Other liabilities on the Balance Sheets. A gain recognized when the Company enters into a coinsurance agreement with a third-party reinsurer is deferred and recorded in Other liabilities on the Balance Sheets. Such gains are amortized into operations over the revenue-producing period or the claims run-off period of the related reinsured policies. These amortized gains are recorded in Fee, commission, and other revenue in the Statements of Operations. (j) Deferred Acquisition Costs Acquisition costs consist of commissions and other incremental costs that are directly related to the successful acquisition of insurance contracts. Acquisition costs are deferred to the extent recoverable from future policy revenues and gross profits. However, acquisition costs associated with insurance contracts recorded under the fair value option are not deferred as guidance related to the fair value option requires that transaction costs are recorded immediately as an expense. For life and annuity products, with the exception of variable annuity contracts issued prior to 2010, acquisition costs are amortized in relation to the present value of expected future gross profits from investments and mortality, morbidity, and expense charges. For variable annuity contracts issued prior to 2010, acquisition costs are amortized in relation to the present value of estimated gross revenues from investments and mortality, morbidity, and expense charges. Acquisition costs for accident and health insurance policies are amortized over the lives of the policies in the same manner as premiums are earned. For traditional life and group life products, such costs are amortized over the projected earnings pattern of the related policies using the same actuarial assumptions used in computing future policy benefit reserves. DAC are reviewed for recoverability and loss recognition, at least annually, and adjusted when necessary. The evaluation is a two-step process where current policy year issues are evaluated for recoverability, and then in-force policies are evaluated for loss recognition. Before assessing recoverability and loss recognition, DAC are capped, if necessary, such that the balance cannot exceed the original capitalized costs plus interest. Changes in assumptions can have an impact on the amount of DAC reported for annuity and life insurance products and their related amortization patterns. In the event experience differs from assumptions or assumptions are revised, the Company is required to record an increase or decrease in DAC amortization expense, which is referred to as DAC unlocking. In general, increases in the estimated investment spreads and fees result in increased expected future profitability and may decrease the rate of DAC amortization, while increases in costs of product guarantees, and lapse/surrender and mortality assumptions reduce the expected future profitability of the underlying business and may increase the rate of DAC amortization. The Company formally evaluates the appropriateness of the best-estimate assumptions on an annual basis. If the economic environment or policyholder behavior changes quickly and substantially, assumptions will be reviewed more frequently to affirm best estimates. Any resulting DAC unlocking is reflected prospectively in Change in deferred acquisition costs, net in the Statements of Operations. Adjustments to DAC are made to reflect the corresponding impact on the present value of expected future gross profits and revenues from unrealized gains and losses on available-for-sale investments used to support policyholder liabilities (commonly known as shadow DAC). These adjustments are included in AOCI and are explained further in the Investments section of this note. Adjustments may also be made to DAC that correspond to deferred annuities and universal life products for investment activity, such as write-downs on other-than-temporarily impaired fixed-maturity securities and realized gains and losses. Management action may result in assumption changes in the DAC models, such as adjustments to future estimated gross profits (EGP) and estimated gross revenues used, as well as in-force management action such as crediting rate changes or index rate cap adjustments. See further discussion of DAC unlocking in note 9. The Company assesses internal replacements on insurance contracts to determine whether such modifications significantly change the contract terms. An internal replacement represents a modification in product benefits, features, rights, or coverages that occurs by the exchange of an in-force insurance contract for a new insurance contract, or by amendment, endorsement, or rider to a contract. If the modification substantially changes the contract, the remaining DAC on the original contract are immediately expensed and any new DAC on the replacement contract are deferred. If the contract modification does not substantially change the contract, DAC amortization on the original contract continues and any new acquisition costs associated with the modification are immediately expensed. (k) Deferred Sales Inducements Sales inducements are product features that enhance the investment yield to the contractholder on the contract. The Company offers an immediate bonus on certain annuity contracts which increases the account value at inception. These annuity sales inducements are deferred when credited to contractholders. DSI are reported in Other assets on the Balance Sheets. They are amortized over the expected life of the contract in a manner similar to DAC and are reviewed annually for recoverability. DSI amortization is recorded in Policyholder benefits, net of recoveries within the Statements of Operations. Adjustments to DSI are made to reflect the estimated corresponding impact on the present value of expected future gross profits and revenues from unrealized gains and losses on available-for-sale investments used to support policyholder liabilities (commonly known as shadow DSI). These adjustments are included in AOCI and are explained further in the Investments section of this note. Adjustments may also be made to DSI for investment activity, such as write-downs on other-than-temporarily impaired fixed-maturity securities, and realized gains and losses. Management action may result in assumption changes in the DSI models, such as adjustments to future EGP used, as well as policyholder changes, such as credited rate changes. (l) Income Taxes The Company and the Company's parent, Allianz Life, file a consolidated federal income tax return with AZOA and many of its wholly-owned subsidiaries. The consolidated tax allocation agreement stipulates that each company participating in the return will bear its share of the tax liability pursuant to certain tax allocation elections under the Internal Revenue Code (IRC) and its related regulations and reimbursement will be in accordance with an intercompany tax reimbursement arrangement . The Company generally will be paid for the tax benefit on its losses and any other tax attributes to the extent it could have obtained a benefit against the Company's post-1990 separate return tax liability. The Company provides for federal income taxes based on amounts the Company believes it ultimately will owe. Inherent in the provision for federal income taxes are estimates regarding the deductibility of certain items and the realization of certain tax credits. In the event the ultimate deductibility of certain items or the realization of certain tax credits differs from estimates, the Company may be required to significantly change the provision for federal income taxes recorded on the Balance Sheets. Any such change could significantly affect the amounts reported within the Statements of Operations. Management uses best estimates to establish reserves based on current facts and circumstances regarding tax exposure items where the ultimate deductibility is open to interpretation. Quarterly, management evaluates the appropriateness of such reserves based on any new developments specific to their fact patterns. Information considered includes results of completed tax examinations, Technical Advice Memorandums, and other rulings issued by the Internal Revenue Service or the tax courts. The Company utilizes the asset and liability method of accounting for income tax. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized within operations in the period that includes the enactment date. Subsequent changes in deferred tax assets and liabilities are recognized in operations or OCI, depending on the nature of the underlying temporary difference. Valuation allowances are established when it is determined that it is more likely than not that the deferred tax asset will not be fully realized or that the related temporary differences will not reverse over time. See note 11 for further details. (m) Separate Account and Annuity Product Guarantees The Company issues variable annuity contracts through its separate account for which investment income and investment gains and losses accrue directly to, and investment risk is borne by, the contractholder. The Company also issues variable-indexed annuity contracts to its customers. These products have investment options similar to fixed-indexed annuities, but allow contractholders to invest in a variety of variable separate account investment options. The Company recognizes gains or losses on transfers from the general account to the separate account at fair value to the extent of contractholder interests in the separate account, which are offset by changes in contractholder liabilities. The Company issues variable annuity and previously issued life contracts through its separate account where the Company provides certain contractual guarantees to the contractholder. These guarantees are in the form of a guaranteed minimum death benefit (GMDB), a guaranteed minimum income benefit (GMIB), a guaranteed minimum accumulation benefit (GMAB), and a guaranteed minimum withdrawal benefit (GMWB). The investments backing the guarantees are held in the general account. These guarantees provide for benefits that are payable to the contractholder in the event of death, annuitization, exercise of the living withdrawal benefit, or at specified dates during the accumulation period. Separate account assets supporting variable annuity contracts represent funds for which investment income and investment gains and losses accrue directly to contractholders. Each fund has specific investment objectives and the assets are carried at fair value. The assets of each account are legally segregated and are not subject to claims that arise out of any other business of the Company. Separate account assets and liabilities are reported as summary totals on the Balance Sheets. Amounts charged to the contractholders for mortality and contract maintenance are included in Premiums and policy fees, net in the Statements of Operations. Administrative and other services are included in Fee, commission, and other revenue in the Statements of Operations. These fees have been earned and assessed against contractholders on a daily or monthly basis throughout the contract period and are recognized as revenue when assessed and earned. Changes in GMDB and GMIB are calculated in accordance with the Financial Services – Insurance Topic of the Accounting Standards Codification (Codification) and are included in Policyholder benefits, net of recoveries in the Statements of Operations. GMAB and GMWB are considered to be embedded derivatives under the Derivatives and Hedging Topic of the Codification, and the changes in these embedded derivatives are included in Change in fair value of annuity and life embedded derivatives in the Statements of Operations. The GMDB net amount at risk is defined as the guaranteed amount that would be paid upon death, less the current accumulated contractholder account value. The GMIB net amount at risk is defined as the current amount that would be needed to fund expected future guaranteed payments less the current contractholder account value, assuming that all benefit selections occur as of the valuation date. The GMAB net amount at risk is defined as the current guaranteed value amount that would be added to the contracts less the current contractholder account value. The GMWB net amount at risk is defined as the current accumulated benefit base amount less the current contractholder account value. The GMDB provides a specified minimum return upon death. The survivor has the option to terminate the contract or continue it and have the death benefit paid into the contract. The Company’s GMDB options have the following features: • Return of Premium • Reset • Ratchet The GMIB is a living benefit that provides the contractholder with a guaranteed annuitization value. The GMIB features are: • Return of Premium • Rollup The GMDB and GMIB liabilities are determined each period by estimating the expected future claims in excess of the associated account balances. The Company regularly evaluates estimates used and adjusts the additional liability balance, with a related charge or credit to Policyholder benefits, net of recoveries in the Statements of Operations , if actual experience or other evidence suggests that earlier assumptions should be revised. The GMAB is a living benefit that provides the contractholder with a guaranteed value that was established at least five years prior at each contract anniversary. This benefit is first available at the fifth contract anniversary, seventh contract anniversary, or tenth contract anniversary depending on the type of contract. Depending on the contractholder’s selection at issue, this value may be either a return of premium or may reflect market gains, adjusted at

Risk Disclosures

Risk Disclosures	12 Months Ended

Risk Disclosures	(3) Risk Disclosures The following is a description of the significant risks facing the Company and how it attempts to mitigate those risks: (a) Credit Risk Credit risk is the risk that issuers of fixed-rate and variable-rate income securities, mortgages on commercial real estate, or other parties with whom the Company has transactions, such as reinsurers and derivative counterparties, default on their contractual obligations, resulting in unexpected credit losses. The Company mitigates this risk by adhering to investment policies and limits that provide portfolio diversification on an asset class, asset quality, creditor, and geographical basis, and by complying with investment limitations from applicable state insurance laws and regulations. The Company considers all relevant objective information available in estimating the cash flows related to structured securities. The Company actively monitors and manages exposures, and determines whether any securities are impaired. The aggregate credit risk is influenced by management’s risk/return preferences, the economic and credit environment, and the ability to manage this risk through liability portfolio management. For derivative counterparties, the Company mitigates credit risk by tracking and limiting exposure to each counterparty through limits that are reported regularly and, once breached, restricts further trades; establishing relationships with counterparties rated BBB+ and higher; and monitoring the credit default swap of each counterparty as an early warning signal to cease trading when credit default swap spreads imply severe impairment in credit quality. The Company executes Credit Support Annexes (CSA) with all active and new counterparties which further limits credit risk by requiring counterparties to post collateral to a segregated account to cover any counterparty exposure. (b) Credit Concentration Risk Credit concentration risk is the risk of increased exposure to significant asset defaults (of a single security issuer or class of security issuers); economic conditions (if business is concentrated in a certain industry sector or geographic area); or adverse regulatory or court decisions (if concentrated in a single jurisdiction) affecting credit. Concentration risk exposure is monitored regularly. The Company’s Finance Committee, responsible for asset/liability management (ALM) issues, recommends an investment policy to the Company’s Board of Directors (BOD) and approves the strategic asset allocation and accompanying investment mandates for an asset manager with respect to asset class. The investment policy and accompanying investment mandates specify asset allocation among major asset classes and the degree of asset manager flexibility for each asset class. The investment policy complies, at a minimum, with state statutes. Compliance with the policy is monitored by the Finance Committee who is responsible for implementing internal controls and procedures. Deviations from the policy are monitored and addressed. The Finance Committee and, subsequently, the BOD review the investment policy at least annually. To further mitigate this risk, internal concentration limits based on credit rating and sector are established and are monitored regularly by Allianz Life on a consolidated basis. Any ultimate obligor group exceeding these limits is placed on a restricted list to prevent further purchases, and the excess exposure may be actively sold down to comply with concentration limit guidelines. Any exceptions require Chief Risk Officer approval and monitoring by the Risk Committee. Further, the Company performs a quarterly concentration risk calculation to ensure compliance with the State of New York basket clause. (c) Liquidity Risk Liquidity risk is the risk that unexpected timing or amounts of cash needed will require liquidation of assets in a market that will result in a realized loss or an inability to sell certain classes of assets such that an insurer will be unable to meet its obligations and contractual guarantees. Liquidity risk also includes the risk that in the event of a company liquidity crisis, refinancing is only possible at higher interest rates. Liquidity risk can be affected by the maturity of liabilities, the presence of withdrawal penalties, the breadth of funding sources, and terms of funding sources. It can also be affected by counterparty collateral triggers as well as whether anticipated liquidity sources, such as credit agreements, are cancelable. The Company manages liquidity within four specific domains: (1) monitoring product development, product management, business operations, and the investment portfolio; (2) setting ALM strategies; (3) managing the cash requirements stemming from the Company’s derivative dynamic economic hedging activities; and (4) establishing a liquidity facility with Allianz Life to provide additional liquidity. The Company has established liquidity risk limits, which are approved by the Company’s Risk Committee, and the Company monitors its liquidity risk regularly. (d) Interest Rate Risk Interest rate risk is the risk that movements in interest rates or interest rate volatility will cause a decrease in the value of an insurer’s assets relative to the value of its liabilities and/or an unfavorable change in prepayment activity resulting in compressed interest margins. The Company has an ALM strategy to align cash flows and duration of the investment portfolio with policyholder liability cash flows and duration. The Company further limits interest rate risk on variable annuity guarantees through economic interest rate hedges. (e) Equity Market Risk Equity market risk is the risk that movements in equity prices or equity volatility will cause a decrease in the value of an insurer’s assets relative to the value of its liabilities. The policy value of the fixed-indexed universal life, fixed-indexed annuity, and variable-indexed annuity products is linked to equity market indices. The Company economically hedges this exposure with derivatives. Variable annuity products may provide a minimum guaranteed level of benefits irrespective of market movements. The Company has adopted an economic hedging program to manage the equity risk of these products. Allianz Life monitors the impacts of equity stress scenarios on assets and liabilities on a consolidated basis regularly and on the Company’s specific basis periodically. Basis risk is the risk that variable annuity hedge asset value changes unexpectedly relative to the value of the underlying separate account funds of the variable annuity contracts. Basis risk may arise from the Company’s inability to directly hedge the underlying investment options of the variable annuity contracts. The Company mitigates this risk through regular review and synchronization of fund mappings, product design features, and hedge design. (f) Operational Risk Operational risk is the risk of loss resulting from inadequate or failed internal processes and systems, from human misbehavior or error, or from external events. Operational risk is comprised of the following seven risk categories: (1) external fraud; (2) internal fraud; (3) employment practices and workplace safety; (4) clients/third-party, products and business practices; (5) damage to physical assets; (6) business disruption and system failure; and (7) execution, delivery, and process management. Operational risk is comprehensively managed through a combination of core qualitative and quantitative activities. The Operational Risk Management framework includes the following key activities: (1) loss data capture identifies historical operational events that meet a designated threshold to ensure transparency and remediation of each event; (2) an integrated risk and control system is performed to proactively manage significant operational risk scenarios throughout the organization; and (3) scenario analyses are conducted to quantify operational risk capital. (g) Legal/Regulatory Risk Legal/regulatory risk is the risk that changes in the legal or regulatory environment in which the Company operates may result in reduced demand for its products or additional expenses not assumed in product pricing. Additionally, the Company is exposed to risk related to how the Company conducts itself in the market and the suitability of its product sales to contract holders. The Company actively monitors all market-related exposure and participates in national and international discussions relating to legal, regulatory, and accounting changes that may impact the business. A formal process exists to assess the Company’s risk exposure to changes in regulation including monitoring by the Compliance and Legal departments and regular reporting to the BOD of all known compliance risks and the effectiveness of the approach used to mitigate such risks. In addition, the Company has implemented suitability standards to mitigate suitability risk. (h) Ratings Risk Ratings risk is the risk that rating agencies change their outlook or rating of the Company. The rating agencies generally utilize proprietary capital adequacy models in the process of establishing ratings for the Company. The Company is at risk of changes in these models and the impact that changes in the underlying business that the Company is engaged in can have on such models. To mitigate this risk, the Company maintains regular communications with the rating agencies and evaluates the impact of significant transactions on such capital adequacy models and considers the same in the design of transactions to minimize the adverse impact of this risk. Stress tests are performed regularly to assess how rating agency capital adequacy models would be impacted by severe economic events. (i) Mortality/Longevity Risk Mortality/longevity risk is the risk that mortality experience is different than the life expectancy assumptions used by the Company to price its products. The Company mitigates mortality risk primarily through reinsurance, whereby the Company cedes a significant portion of its mortality risk to third parties. The Company also manages mortality risk through the underwriting process. Both mortality and longevity risks are managed through the review of life expectancy assumptions and experience in conjunction with active product management. (j) Lapse Risk Lapse risk is the risk that actual lapse experience evolves differently than the assumptions used for pricing and valuation exercises leading to a significant loss in Company value and/or income. The Company mitigates this risk by performing sensitivity analysis at the time of pricing to affect policy design, regular ALM analysis, and exercising management levers at issue, as well as post-issue as experience evolves. Policyholder experience is monitored regularly. (k) Cyber Security Risk Cyber security risk is the risk of losses due to external and/or internal attacks impacting the confidentiality, integrity, and/or availability of key systems, data, and processes reliant on digital technology. The Company has implemented preventative, detective, response, and recovery measures including firewalls, intrusion detection and prevention, advanced malware detection, spyware and anti-virus software, email protection, email and laptop encryption, web content filtering, web application firewalls, and regular scanning of all servers and network devices to identify vulnerabilities. Controls are implemented to prevent and review unauthorized access. (l) Reinsurance Risk Reinsurance risk is the risk that reinsurance companies default on their obligation where the Company has ceded a portion of its insurance risk. The Company uses reinsurance to limit its risk exposure to certain business lines and to enable better capital management. Reinsurance contracts do not relieve the Company from its obligations to policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company mitigates this risk by requiring certain counterparties to meet thresholds related to the counterparty’s credit rating, exposure, or other factors. If the thresholds are not met by those counterparties, they are required to establish a trust or letter of credit backed by assets meeting certain quality criteria. All arrangements are regularly monitored to determine whether trusts or letters of credit are sufficient to support the ceded liabilities and that their terms are being met. Also, the Company reviews the financial standings and ratings of its reinsurance counterparties and monitors concentrations of credit risk to minimize its exposure to significant losses from reinsurer insolvencies regularly.

Fixed-maturity securities not due at a single maturity date have been presented in the year of final contractual maturity. Structured securities are shown separately, as they are not due at a single maturity. As of December 31, 2017 and 2016 , investments with a fair value of $1,688 and $1,699 , respectively were held on deposit as required by statutory regulations. The Company’s fixed-maturity security portfolios include mortgage-backed securities. Due to the high quality of these investments and the lack of subprime loans within the securities, the Company does not have a material exposure to subprime mortgages. (b) Unrealized Investment Losses The following table summarizes the fair value and related unrealized losses on available-for-sale securities that have been in a continuous loss position for the respective years ended December 31 are shown below: 12 months or less Greater than 12 months Total Fair value Unrealized losses Fair value Unrealized losses Fair value Unrealized losses 2017: Fixed-maturity securities, available-for-sale: U.S. government $ 34,218 400 1,986 50 36,204 450 Foreign government 2,933 51 — — 2,933 51 Corporate securities 116,272 1,035 41,688 1,223 157,960 2,258 Mortgage-backed securities 90,852 677 54,608 2,146 145,460 2,823 Total temporarily impaired securities $ 244,275 2,163 98,282 3,419 342,557 5,582 12 months or less Greater than 12 months Total Fair value Unrealized losses Fair value Unrealized losses Fair value Unrealized losses 2016: Fixed-maturity securities, available-for-sale: U.S. government $ 11,713 103 — — 11,713 103 States and political subdivisions 4,286 187 — — 4,286 187 Corporate securities 132,387 3,313 7,253 426 139,640 3,739 Mortgage-backed securities 102,435 3,483 1,622 75 104,057 3,558 Total temporarily impaired securities $ 250,821 7,086 8,875 501 259,696 7,587 As of December 31, 2017 and 2016 , there were 160 and 149 available-for-sale fixed-maturity security holdings that were in an unrealized loss position, respectively. As of December 31, 2017 and 2016 , of the total amount of unrealized losses, $5,498 or 98.6% and $7,250 or 95.6% , respectively, are related to unrealized losses on investment grade securities. Investment grade is defined as a security having a credit rating of Aaa, Aa, A, or Baa from Moody’s or a rating of AAA, AA, A, or BBB from Standards and Poor’s (S&P), or a NAIC rating of 1 or 2 if a Moody’s or S&P rating is not available. Unrealized losses on securities are principally related to changes in interest rates or changes in sector spreads from the date of purchase. As contractual payments continue to be met, management continues to expect all contractual cash flows to be received and does not consider these investments to be other-than-temporarily impaired.

The total collateral posted for exchange-traded derivatives at December 31, 2017 and 2016 , had a fair value of $60,669 and $ 55,611 , respectively, and is included in Fixed-maturity securities on the Balance Sheets. The Company retains ownership of the exchange-traded collateral, but the collateral resides in an account designated by the exchange. The collateral is subject to specific exchange rules regarding rehypothecation. The Company has no collateral posted for OTC derivatives as of December 31, 2017 and 2016 . The Company posts collateral to OTC counterparties based upon exposure amounts. The Company retains ownership of the OTC collateral. Embedded Derivatives The Company issues certain variable annuity products with guaranteed minimum benefit riders, including GMWB and GMAB, which are measured at fair value separately from the host variable annuity contract, with changes in fair value reported in Change in fair value of annuity and life embedded derivatives within the Statements of Operations. These embedded derivatives are classified within Account balances and future policy benefit reserves on the Balance Sheets. Certain fixed-indexed annuity products and universal life policies include equity-indexed features, which are separated as an embedded derivative, and referred to as a market value liability option (MVLO). This embedded derivative is reported within Account balances and future policy benefit reserves on the Balance Sheets with changes in fair value reported in Change in fair value of annuity and life embedded derivatives within the Statements of Operations. The following table presents a summary of the fair values of the Company’s embedded derivative instruments reported on the Balance Sheets as of December 31 : 2017 2016 GMWB $ (127,945 ) (144,631 ) GMAB (10,518 ) (16,594 ) MVLO (16,707 ) (15,896 ) Total embedded derivative instruments $ (155,170 ) (177,121 ) The following table presents the gains or losses recognized in income on the various nonqualifying freestanding derivative instruments and embedded derivatives: Amount of gain (loss) on derivatives recognized for the years ended December 31, Location in the Statements of Operations 2017 2016 2015 GMWB Change in fair value of annuity and life embedded derivatives $ 16,686 2,659 (54,413 ) GMAB Change in fair value of annuity and life embedded derivatives 6,062 8,844 (11,755 ) MVLO Change in fair value of annuity and life embedded derivatives (1,639 ) 1,688 5,292 Total change in fair value of annuity and life embedded derivatives 21,109 13,191 (60,876 ) Futures Change in fair value of assets and liabilities (32,763 ) (32,111 ) (11,861 ) OTC options Change in fair value of assets and liabilities 10,706 (4,497 ) 692 IRS Change in fair value of assets and liabilities 10,133 5,690 23,296 TRS Change in fair value of assets and liabilities (28 ) 1,105 — Total change in fair value of assets and liabilities (11,952 ) (29,813 ) 12,127 MVLO Premiums and policy fees, net 788 745 534 MVLO Policyholder benefits, net of recoveries 40 196 127 Total derivative gain (loss), net $ 9,985 (15,681 ) (48,088 ) Offsetting Assets and Liabilities Certain financial instruments and derivative instruments are eligible for offset on the Balance Sheets under GAAP. The Company’s derivative instruments are subject to master netting arrangements and collateral arrangements. A master netting arrangement with a counterparty creates a right of offset for amounts due to and from that same counterparty that is enforceable in the event of a default or bankruptcy. The Company’s policy is to recognize amounts subject to master netting arrangements on a gross basis on the Balance Sheets. The following tables present additional information about derivative assets and liabilities subject to an enforceable master netting arrangement as of the dates indicated: December 31, 2017 Gross amounts not offset in the Balance Sheet Gross amounts recognized Gross amounts offset in the Balance Sheet Net amounts presented in the Balance Sheet Financial instruments (1) Collateral (received) / pledged Net amounts Derivative assets $ 51,362 — 51,362 (21,105 ) (28,732 ) 1,525 Derivative liabilities (21,105 ) — (21,105 ) 21,105 — — Net derivatives $ 30,257 — 30,257 — (28,732 ) 1,525 December 31, 2016 Gross amounts not offset in the Balance Sheet Gross amounts recognized Gross amounts offset in the Balance Sheet Net amounts presented in the Balance Sheet Financial instruments (1) Collateral (received) / pledged Net amounts Derivative assets $ 32,993 — 32,993 (15,416 ) (10,674 ) 6,903 Derivative liabilities (15,416 ) — (15,416 ) 15,416 — — Net derivatives $ 17,577 — 17,577 — (10,674 ) 6,903 (1) Represents the amount of assets or liabilities that could be offset by liabilities or assets with the same counterparty under master netting or similar arrangements that management elects not to offset on the Balance Sheet. In the tables above, the gross amounts of assets or liabilities as presented on the Balance Sheets are offset first by financial instruments that have the right of offset under master netting or similar arrangements, then any remaining amount is reduced by the amount of cash and securities collateral.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2017
Fair Value Measurements	(6) Fair Value Measurements The Fair Value Measurement Topic of the Codification establishes a fair value hierarchy that prioritizes the inputs used in the valuation techniques to measure fair value. Level 1 – Unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date. Level 2 – Valuations derived from techniques that utilize observable inputs, other than quoted prices included in Level 1, which are observable for the asset or liability either directly or indirectly, such as: (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. (c) Inputs other than quoted prices that are observable. (d) Inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 – Valuations derived from techniques in which the significant inputs are unobservable. Level 3 fair values reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). The Company has analyzed the valuation techniques and related inputs, evaluated its assets and liabilities reported at fair value, and determined an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs. Based on the results of this evaluation and investment class analysis, each financial asset and liability was classified into Level 1, 2, or 3. The following presents the assets and liabilities measured at fair value on a recurring basis and their corresponding level in the fair value hierarchy at December 31: 2017 Total Level 1 Level 2 Level 3 Assets Fixed-maturity securities, available-for-sale: U.S. government $ 77,660 77,660 — — States and political subdivisions 11,005 — 11,005 — Foreign government 2,933 — 2,933 — Corporate securities 640,875 — 640,875 — Mortgage-backed securities 258,750 — 258,750 — Derivative assets 51,362 — 51,362 — Equity securities, trading 8,826 8,826 — — Separate account assets 2,300,462 2,300,462 — — Total assets $ 3,351,873 2,386,948 964,925 — Liabilities Derivative liabilities $ (21,105 ) — (21,105 ) — Reserves at fair value (1) (624,157 ) — — (624,157 ) Total liabilities $ (645,262 ) — (21,105 ) (624,157 ) 2016 Total Level 1 Level 2 Level 3 Assets Fixed-maturity securities, available-for-sale: U.S. government $ 49,217 49,217 — — States and political subdivisions 10,644 — 10,644 — Corporate securities 509,279 — 508,237 1,042 Mortgage-backed securities 182,391 — 182,391 — Derivative assets 32,993 — 32,993 — Equity securities, trading 7,539 7,539 — — Separate account assets 2,255,576 2,255,576 — — Total assets $ 3,047,639 2,312,332 734,265 1,042 Liabilities Derivative liabilities $ (15,416 ) — (15,416 ) — Reserves at fair value (1) (399,260 ) — — (399,260 ) Total liabilities $ (414,676 ) — (15,416 ) (399,260 ) (1) Reserves at fair value are reported in Account balances and future policy benefit reserves on the Balance Sheets. The following is a discussion of the methodologies used to determine fair values for the assets and liabilities listed in the above table. These fair values represent an exit price (i.e., what a buyer in the marketplace would pay for an asset in a current sale or charge to transfer a liability). (a) Valuation of Fixed-Maturity Securities and Equity Securities The fair value of fixed-maturity securities and equity securities is based on quoted market prices in active markets when available. Based on the market data, the securities are categorized into asset class, and based on the asset class of the security, appropriate pricing applications, models and related methodology, and standard inputs are utilized to determine what a buyer in the marketplace would pay for the security in a current sale. When quoted prices are not readily available or in an inactive market, standard inputs used in the valuation models, listed in approximate order of priority, include, but are not limited to, benchmark yields, reported trades, Municipal Securities Rulemaking Board reported trades, Nationally Recognized Municipal Securities Information Repository material event notices, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, and industry and economic events. In some cases, including private placement securities and certain difficult-to-price securities, internal pricing models may be used that are based on market proxies. Generally, U.S. Treasury securities and exchange-traded stocks are included in Level 1. Most bonds for which prices are provided by third-party pricing sources are included in Level 2, because the inputs used are market observable. Bonds for which prices were obtained from broker quotes, certain bonds without active trading markets and private placement securities that are internally priced are included in Level 3. At December 31, 2017 and 2016 , private placement securities of $0 and $1,042 , respectively, were included in Level 3. Internal pricing models based on market proxy spread and U.S. Treasury rates are used to value these holdings. (b) Valuation of Derivatives Active markets for OTC options do not exist. The fair value of OTC options is derived internally, by calculating their expected discounted cash flows, using a set of calibrated, risk-neutral stochastic scenarios, including a market data monitor, a market data model generator, a stochastic scenario calibrator, and the actual asset pricing calculator. The valuation results are reviewed by Management via the Pricing Committee. OTC options that are internally priced and IRS are included in Level 2, because they use market observable inputs. TRS are included in Level 3 because they use valuation techniques in which significant inputs are unobservable. Certain derivatives are priced using external third-party vendors. The Company has controls in place to monitor the valuations of these derivatives. Using market observable inputs, IRS prices are derived from a third-party source and are independently recalculated internally and reviewed for reasonableness at the position level on a monthly basis. TRS prices are obtained from the respective counterparties. These prices are also internally recalculated and reviewed for reasonableness at the position level on a monthly basis. (c) Valuation of Separate Account Assets Separate account assets are carried at fair value, which is based on the fair value of the underlying assets. Funds in the separate account are primarily invested in variable investment option funds with the following investment types: bond, domestic equity, international equity, or specialty. Variable investment option funds are included in Level 1 because their fair value is based on net asset values that are quoted as prices (unadjusted) in an active, observable market. Additionally, the separate account holds certain money market funds which are also included in Level 1 because their fair value is based on quoted prices (unadjusted) in an active, observable market. (d) Valuation of Reserves at Fair Value Reserves at fair value principally include the equity-indexed features contained in fixed-indexed annuity and life products, certain variable annuity riders and variable-indexed annuity products. Fair values of the embedded derivative liabilities are calculated based on internally developed models, because active, observable markets do not exist for these liabilities. The fair value is derived from techniques in which one or more significant inputs are unobservable and are included in Level 3. These fair values represent the Company’s best estimate of an amount that could be realized in a current market exchange absent actual market exchanges. The fair value of the embedded derivative contained in the fixed-indexed annuity products is the sum of the current year’s option value projected stochastically, the projection of future index growth at the option budget, and the historical interest/equity-indexed credits. The valuation of the embedded derivative includes an adjustment for the Company’s own credit standing and a risk margin for noncapital market inputs. The fair value of the embedded derivative contained in the fixed-indexed universal life insurance products is the amount of the current year’s option value in excess of a fixed crediting valuation over the remainder of the policy year. The valuation of the embedded derivative includes an adjustment for the Company’s own credit standing and a risk margin for noncapital market inputs. The Company issues certain variable annuity products with GMWB and GMAB riders. The fair value for these riders is estimated using the present value of future benefits minus the present value of future fees using actuarial and capital market assumptions related to the projected cash flows over the expected lives of the contracts. A risk neutral valuation methodology is used under which the cash flows from the riders are projected under multiple capital market scenarios using observable market interest rates. The valuation of these riders includes an adjustment for the Company’s own credit standing and a risk margin for noncapital market inputs. The Company’s own credit adjustment is determined by taking into consideration publicly available information on industry default risk with considerations for the Company’s own credit profile. Risk margin is incorporated into the valuation model to capture the noncapital market risks of the instrument, which represent the additional compensation a market participant would require to assume the risks related to the uncertainties of certain actuarial assumptions including surrenders, annuitization, premium persistency, and future equity index caps or participation rates. The establishment of the risk margin requires the use of significant management judgment. Market conditions including, but not limited to, changes in interest rates, equity indices, market volatility, changes in the Company’s own credit standing, and variations in actuarial assumptions regarding contractholder behavior and risk margins related to noncapital market inputs may result in significant fluctuations in the fair value of embedded derivatives that could materially affect net income. The Company elected the fair value option for insurance contracts related to the variable-indexed annuity product. The fair value is calculated internally using the present value of future expected cash flows, floored at the current contract value. Future expected cash flows are generated using contractual features, actuarial assumptions, and market emergence over a complete set of market consistent scenarios. Cash flows are then averaged over the scenario set and discounted back to the valuation date using the appropriate discount factors adjusted for nonperformance risk on the noncollateralized portions of the contract. (e) Level 3 Rollforward The following table provides a reconciliation of the beginning and ending balances for the Company’s Level 3 assets and liabilities measured at fair value on a recurring basis: 2017 Fixed-maturity securities, Corporate securities Derivative assets Derivative liabilities Reserves at fair value (1) Balance, beginning of year $ 1,042 — — (399,260 ) Total realized/unrealized gains (losses) included in: Net income (loss) 17 1,036 (1,063 ) (22,738 ) Other comprehensive income (loss) (42 ) — — — Purchases and issuances — — — (222,727 ) Sales and settlements (1,017 ) (1,036 ) 1,063 20,568 Balance, end of year $ — — — (624,157 ) Gains (losses) included in net income related to financial instruments still held at the end of the year $ — — — (22,738 ) 2016 Fixed-maturity securities, Corporate securities Derivative assets Derivative liabilities Reserves at fair value (1) Balance, beginning of year $ 1,047 — — (265,884 ) Total realized/unrealized gains (losses) included in: Net income (loss) — 7,774 (7,189 ) (8,708 ) Other comprehensive income (loss) (5 ) — Purchases and issuances — (140,054 ) Sales and settlements — (7,774 ) 7,189 15,386 Balance, end of year $ 1,042 — — (399,260 ) Gains (losses) included in net income related to financial instruments still held at the end of the year $ — — — (8,708 ) (1) The Company classifies realized and unrealized gains (losses) on Reserves at fair value as unrealized gains (losses) for purposes of disclosure in this table because the Company monitors Reserves at fair value as a whole unit and does not track realized gains (losses) on a contract-by-contract basis. (f) Transfers The Company reviews its fair value hierarchy classifications annually. Transfers between levels occur when there are changes in the observability of inputs and market activity. Transfers into and/or out of Levels 1, 2, and 3 are reported as of the end of the period in which the change occurs. There were no transfers of securities into or out of Level 3 for the years ended December 31, 2017 and 2016 . In addition, there were no transfers of securities between Level 1 and Level 2 for the years ended December 31, 2017 and 2016 . (g) Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs The following table provides a summary of the significant unobservable inputs used in the fair value measurements developed by the Company or reasonably available to the Company of Level 3 assets and liabilities on a recurring basis at December 31: 2017 Fair value Valuation technique Unobservable input Range (weighted average) Reserves at Fair Value: MVLO $ (16,707 ) Discounted cash flow Annuitizations 0 - 25% Surrenders 0 - 25% Mortality * 0 - 100% Withdrawal Benefit Election 0 - 50% GMWB and GMAB (138,463 ) Discounted cash flow Surrenders 0.5% - 35% Mortality * 0% - 100% Variable-indexed annuity (468,987 ) Contract value N/A ** N/A** 2016 Fair value Valuation technique Unobservable input Range (weighted average) Fixed-maturity securities: Available-for-sale: Corporate securities $ 1,042 Discounted cash flow Option adjusted spread *** 72 (72) Reserves at Fair Value: MVLO (15,896 ) Discounted cash flow Annuitizations 0 – 25% Surrenders 0 – 25% Mortality * 0 – 100% Withdrawal Benefit Election 0 – 50% GMWB and GMAB (161,225 ) Discounted cash flow Surrenders 0.5 – 35% Mortality * 0 – 100% Variable-indexed annuity (222,139 ) Contract value N/A ** N/A ** * Mortality assumptions are derived from the Annuity 2000 Mortality Table. See note 12 for further discussion. ** Unobservable inputs are not applicable as the fair value of the variable-indexed annuity reserve is floored at contract value. *** No range is applicable due to only one security within classification. (h) Sensitivity of Fair Value Measurements to Changes in Unobservable Inputs Fixed-maturity securities: The primary unobservable input used in the discounted cash flow model is a corporate index option adjusted spread (OAS). The corporate index OAS used is based on a security's sector, rating, and average life. A significant increase (decrease) of the corporate index OAS in isolation could result in a decrease (increase) in fair value. Reserves at fair value: A significant increase (decrease) in the utilization of annuitization benefits could result in a higher (lower) fair value. A significant decrease (increase) in mortality rates, surrender rates, or utilization of lifetime income benefits could result in a higher (lower) fair value. (i) Nonrecurring Fair Value Measurements Occasionally, certain assets and liabilities are measured at fair value on a nonrecurring basis. There were no nonrecurring fair value adjustments recorded in 2017 , 2016 , or 2015 . (j) Fair Value of Financial Instruments Carried at Other Than Fair Value The following table presents the carrying amount and fair value of certain financial instruments that are not reported at fair value at December 31: 2017 Carrying Fair value amount Level 1 Level 2 Level 3 Total Financial assets Policy loans $ 400 — 400 — 400 Short-term securities 32,454 32,454 — — 32,454 Cash equivalents 37,204 37,204 — — 37,204 Financial liabilities Investment contracts (423,710 ) — — (423,874 ) (423,874 ) Separate account liabilities (2,300,462 ) (2,300,462 ) — — (2,300,462 ) 2016 Carrying Fair value amount Level 1 Level 2 Level 3 Total Financial assets Policy loans $ 338 — 338 — 338 Cash equivalents 56,714 56,714 — — 56,714 Financial liabilities Investment contracts (448,009 ) — — (448,876 ) (448,876 ) Separate account liabilities (1) (2,255,576 ) (2,255,576 ) — — (2,255,576 ) (1) The previously issued 2016 Financial Statements improperly disclosed Separate account liabilities as a financial instrument measured at fair value on a recurring basis. Separate account liabilities has been corrected in the above table to conform with current year presentation as it is carried at other than fair value. Policy loans are supported by the underlying cash value of the policies and are carried at unpaid principal balances plus accrued investment income. As policy loans function like demand deposits, the current carrying value is the only market price at which the transaction could be settled. Due to the lack of an active market and uncertainty on receiving contractual cash flows, the Company believes the carrying value approximates fair value. The carrying value of the Company's short-term securities is considered a reasonable estimate of fair value due to their short-term maturities. Cash equivalents include short-term, highly liquid debt instruments purchased with an original maturity of three months or less, short-term government money market funds, and overnight commercial paper. Due to the short-term nature of these investments, carrying value is deemed to approximate fair value. The fair value of the cash equivalents is based on quoted market prices. Investment contracts include certain reserves related to annuity and life products. These reserves are included in Account balances and future policy benefit reserves on the Balance Sheets. The fair values of the investment contracts are determined by testing amounts payable on demand against discounted cash flows using market interest rates commensurate with the risks involved, including consideration of the Company’s own credit standing and a risk margin for noncapital market inputs. Separate account liabilities are recorded at the amount credited to the contractholder, which reflects the change in fair value of the corresponding separate account assets including contractholder deposits less withdrawals and fees. As such, the carrying value is deemed to approximate fair value.

Financing Receivables

Financing Receivables	(7) Financing Receivables The Company’s financing receivables are comprised of nontrade receivables. Nontrade receivables are amounts for policy or contract premiums due from the agents and broker-dealers, or amounts due from reinsurers. The nontrade receivables are evaluated on a collective basis for impairment unless circumstances arise that warrant individual evaluation. For additional information, see receivables section of note 2. Credit Quality Indicators The Company’s nontrade receivables are analyzed for credit risk based upon the customer classification of the agent or reinsurer. The nontrade receivable and allowance for credit losses by customer classification as of December 31 are shown below: 2017 2016 Agent Reinsurer Total Agent Reinsurer Total Nontrade receivables $ 52 48 100 43 54 97 Allowance for credit losses (40 ) — (40 ) (43 ) — (43 ) Net nontrade receivables $ 12 48 60 — 54 54 Rollforward of Allowance for Credit Losses In 2017 and 2016 , the Company reevaluated the allowance related to the financing receivable and changed the provision by $ (3) and $ 10 , respectively. Past-Due Aging Analysis Aging analysis of past-due nontrade financing receivables as of December 31 is shown below: 31-60 days past due 61-90 days past due Greater than 90 days past due Total past due Current Total 2017 $ 26 1 40 67 32 99 2016 22 1 43 66 31 97 As of December 31, 2017 and 2016 , the Company’s financing receivables did not include any balances which are on a nonaccrual status, classified as a troubled debt restructuring, or impaired without a corresponding allowance for credit loss.

Reinsurance

Reinsurance	12 Months Ended
	Dec. 31, 2017
Reinsurance	(8) Reinsurance The Company primarily enters into reinsurance agreements to manage risk resulting from its life and accident and health businesses, as well as businesses the Company has chosen to exit. In the normal course of business, the Company seeks to limit its exposure to loss by ceding risks under yearly renewal term and coinsurance. The Company generally retained between $50 and $1,500 coverage per individual life depending on the type of policy for the years ended December 31, 2017 and 2016 . The Company monitors the financial exposure and financial strength of the reinsurers on an ongoing basis. The Company attempts to mitigate risk by securing recoverable balances with various forms of collateral, including arranging trust accounts and letters of credit with certain reinsurers. The effect of reinsurance on premiums is disclosed in Schedule IV in the Financial Statements. The effect of reinsurance on benefits for the respective years ended December 31 is shown below: 2017 2016 2015 Direct benefits Life $ 630 659 860 Annuities 1,869 2,432 81,687 Accident and health 6,203 3,620 6,220 Total direct benefits 8,702 6,711 88,767 Less: Ceded to other companies Life 354 535 412 Accident and health 587 564 844 Total ceded to other companies 941 1,099 1,256 Total benefits $ 7,761 5,612 87,511 Components of the Company's reinsurance and investment contract recoverables as of December 31 are shown below: 2017 2016 Life $ 178 337 Accident and health 4,127 3,760 Total reinsurance and investment contract recoverables $ 4,305 4,097 The Life, Annuities, and Accident and health categories presented in the tables above are prescribed splits based on product and will differ from the results of the segments disclosed within note 19. The Company did not write off any uncollectible recoverables during 2017 or 2016 .

As a result, the deferred taxes recorded on the Balance Sheets were revalued to reflect the reduction in the future corporate tax rate. (c) Components of Deferred Tax Assets and Liabilities on the Balance Sheet Tax effects of temporary differences giving rise to the significant components of the net deferred tax asset (liability). The net deferred tax asset (liability) on the Balance Sheets at December 31 is as follows: 2017 2016 Deferred tax assets: Policy reserves $ 138,726 151,608 Expense accruals — 711 Total deferred tax assets 138,726 152,319 Deferred tax liabilities: Policy reserves (2,536 ) — Deferred acquisition costs (22,783 ) (41,247 ) Due and deferred premium (7 ) (13 ) Net unrealized gains on investments (5,261 ) (5,801 ) Investment income (89,931 ) (75,704 ) Expense accruals (17 ) — Total deferred tax liabilities (120,535 ) (122,765 ) Net deferred tax asset (liabilities) $ 18,191 29,554 As a result of the enactment of the Tax Act of 2017, the Company was required to revalue the deferred taxes for Policy reserves held. As the effect from the Policyholder reserves revaluation will be recognized in taxable income on a straight-line basis over the next eight year period beginning January 1, 2018, a deferred tax liability is recognized in the same amount as the deferred tax asset. Both the deferred tax asset and liability are recorded as of December 31, 2017 and are presented on a gross basis in the table above. Although realization is not assured, the Company believes it is not necessary to establish a valuation allowance for ordinary deferred tax assets, as it is more likely than not the deferred tax assets will be realized principally through future reversals of existing ordinary taxable temporary differences and future ordinary taxable income. For deferred tax assets that are capital in nature, considering all objective evidence and the available tax planning strategy, it is more likely than not the deferred tax assets that are capital in nature will be realized and no valuation allowance is required. The amount of the ordinary and capital deferred tax assets considered realizable could be reduced in the near term if estimates of future reversals of existing taxable temporary differences and future ordinary and capital taxable income are reduced. Income taxes (received)/paid by the Company were $ (248) , $ 9,714 , and $ 4,405 , in 2017 , 2016 , and 2015 , respectively. At December 31, 2017 and 2016 , respectively, the Company had a tax (receivable)/payable from AZOA of $ (5,648) and $ 180 reported in Other assets or Other liabilities on the Balance Sheets. The Company is included in the consolidated group for which AZOA files a federal income tax return on behalf of all group members. As a member of the AZOA consolidated group, the Company is no longer subject to U.S. federal and non-U.S. income tax examinations for years prior to 2014, though examinations of combined returns filed by AZOA, which include the Company by certain U.S. state and local tax authorities, may still be conducted for 2008 and subsequent years. The last Internal Revenue Service examination of AZOA involved amended returns filed by AZOA for the 2011 tax year. This examination concluded in October 2017 with the Internal Revenue Service accepting the amended returns as filed. The Internal Revenue Service has also initiated examinations of AZOA’s 2015 and 2016 income tax returns. In accordance with the Income Taxes Topic of the Codification, the Company recognizes liabilities for certain unrecognized tax benefits. The Company had no unrecognized tax benefits as of December 31, 2017 and 2016 . The Company does not expect any significant changes related to unrecognized tax benefits during the next 12 months. The Company recognizes the changes in unrecognized tax benefits and related accrued interest and penalties in federal income tax expense. The Company did not recognize any expense related to interest and penalties at December 31, 2017 and 2016 .

Separate Accounts and Annuity Product Guarantees	(12) Separate Account and Annuity Product Guarantees The following assumptions were used to determine the GMDB and GMIB liabilities as of December 31, 2017 and 2016 : • 100 stochastically generated investment performance scenarios. • Mean investment performance assumption of 6.5% in 2017 and 2016 . • Volatility assumption of 13.4% in 2017 and 2016 . • For 2017 and 2016 , the mortality assumption is based on the Annuity 2000 mortality table for all variable products. The past mortality improvement is based on gender distinct mortality loads varying by attained age, and future mortality improvement factors are based on gender distinct projection scales varying by attained age and subject to grading factors. • Lapse rates vary by contract type and duration. As of December 31, 2017 and 2016, spike rates could approach 60% and 40%, respectively, with an ultimate rate around 15%. • Discount rates vary by contract type and equal an assumed long-term investment return (see mean investment performance assumption above), less the applicable mortality and expense rate. • GMIB contracts contain a dynamic lapse assumption. For example, if the contract is projected to have a large additional benefit, then it becomes less likely to lapse. The following assumptions were used to determine the GMAB and GMWB liabilities as of December 31, 2017 and 2016 : • 1000 stochastically generated investment performance scenarios. • Market volatility assumptions vary by fund type and grade from a current volatility number to long-term assumptions over one year as shown below: 2017 2016 Fund index type Current volatility Long-term forward volatility Current volatility Long-term forward volatility Large cap 13.4 % 18.0 % 16.3 % 18.1 % Bond 3.4 3.9 3.4 3.9 International 13.7 21.2 16.8 21.4 Small cap 17.4 21.5 20.3 21.5 • For 2017 and 2016 , the mortality assumption is based on the Annuity 2000 mortality table for all variable products. The past mortality improvement is based on gender distinct mortality loads varying by attained age, and future mortality improvement factors are based on gender distinct projection scales varying by attained age and subject to grading factors. • Lapse rates vary by contract type and duration. As of December 31, 2017 and 2016, spike rates could approach 60% and 40%, respectively, with an ultimate rate around 15%.

Accident and Health Claim Reser

Accident and Health Claim Reserves	12 Months Ended
	Dec. 31, 2017
Accident and Health Claim Reserves	(13) Accident and Health Claim Reserves Accident and health claim reserves are based on estimates that are subject to uncertainty. Uncertainty regarding reserves of a given accident year is gradually reduced as new information emerges each succeeding year, thereby allowing more reliable reevaluations of such reserves. While management believes that reserves as of December 31, 2017 , are appropriate, uncertainties in the reserving process could cause reserves to develop favorably or unfavorably in the near term as new or additional information emerges. Any adjustments to reserves are reflected in the operating results of the periods in which they are made. Movements in reserves could significantly impact the Company’s future reported earnings. Activity in the accident and health claim reserves is summarized as follows: 2017 2016 2015 Balance at January 1, net of reinsurance and investment contract recoverables of $544, $497, and $360, respectively $ 3,877 3,504 2,136 Incurred related to: Current year 2,026 1,504 2,173 Prior years 248 (361 ) (154 ) Total incurred 2,274 1,143 2,019 Paid related to: Current year 85 85 42 Prior years 1,199 685 609 Total paid 1,284 770 651 Balance at December 31, net of reinsurance and investment contract recoverables of $622, $544, and $497, respectively $ 4,867 3,877 3,504 Prior year incurred claim reserves for 2017 were unfavorable as a result of re-estimation of unpaid claims and claim adjustment expenses, principally on individual LTC line of business. Prior year incurred claim reserves for 2016 reflect favorable development as a result of re-estimation of unpaid claims and claim adjustment expenses, principally on LTC and group health lines of business. Prior year incurred claims reserve for 2015 reflect favorable claim development with the group marketing and individual long term care lines of business.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies	(14) Commitments and Contingencies The Company is or may become subject to claims and lawsuits that arise in the ordinary course of business. In the opinion of management, the ultimate resolution of any such known litigation will not have a material adverse effect on the Company’s financial position. The Company is contingently liable for possible future assessments under regulatory requirements pertaining to insolvencies and impairments of unaffiliated insurance companies. Provision has been made for assessments currently received and assessments anticipated for known insolvencies. The financial services industry, including mutual funds, variable and fixed annuities, life insurance, distribution companies, and broker-dealers, is subject to close scrutiny by regulators, legislators, and the media. Federal and state regulators, such as state insurance departments, state securities departments, the SEC, the Financial Industry Regulatory Authority, and other regulatory bodies regularly make inquiries and conduct examinations or investigations concerning various selling practices, including suitability reviews, product exchanges, sales to seniors, and compliance with, among other things, insurance and securities law. The Company is subject to ongoing market conduct examinations and investigations by regulators, which may have a material adverse effect on the Company. It can be expected that annuity and life product designs and sales practices will be an ongoing source of regulatory scrutiny and enforcement actions, litigation, and rulemaking. Private litigation regarding sales practices is ongoing against a number of insurance companies. These matters could result in legal precedents and new industry-wide legislation, rules, and regulations that could significantly affect the financial services industry, including life insurance and annuity companies. It is unclear at this time whether any such litigation or regulatory actions will have a material adverse effect on the Company in the future. When evaluating litigation, claims, and assessments, management considers the nature of the litigation, progress of the case, opinions and views of legal counsel, as well as prior experience in similar cases. Management uses this information to assess whether a loss is probable and if the amount of loss can be reasonably estimated prior to making any accruals. The Company leases office space and equipment from an affiliate (see further information in note 16). The future minimum lease payments required under operating leases are as follows: 2018 $ 24 2019 24 2020 13 2021 — 2022 — 2023 and beyond — Total $ 61

Statutory Financial Data and Dividend Restrictions	(17) Statutory Financial Data and Dividend Restrictions Statutory accounting practices prescribed or permitted by the Company’s state of domicile are directed toward insurer solvency and protection of policyholders. Accordingly, certain items recorded in financial statements prepared under GAAP are excluded or vary in calculation in determining statutory policyholders’ surplus and gain from operations. Currently, these items include, among others, DAC, deferred taxes, receivables (which are more than 90 days past due), reinsurance, and certain investments. Additionally, account balances and future policy benefit reserves calculated for statutory reporting do not include provisions for withdrawals. The Company’s statutory capital and surplus reported in the statutory annual statement filed with the State of New York as of December 31, 2017 and 2016 was $173,058 and $202,130 , respectively. The Company’s net gain from operations reported in the statutory annual statement filed with the State of New York for the years end December 31, 2017 and 2016 , was $34,435 and $58,324 , respectively. The Company is required to meet minimum statutory capital and surplus requirements. The Company’s statutory capital and surplus as of 2017 and 2016 were in compliance with these requirements. The maximum amount of dividends that can be paid by New York insurance companies to stockholders without prior approval of the Department is subject to restrictions relating to statutory earned surplus, also known as unassigned funds. Unassigned funds are determined in accordance with the accounting procedures and practices governing preparation of the statutory annual statement. In accordance with New York statutes, the Company may declare and pay from its Unassigned surplus cash dividends of not more than the greater of 10% of its beginning-of-the year statutory surplus, or its net gain from operations of the insurer, not including realized gains, for the 12-month period ending the 31st day of the preceding year. Based on these restrictions, ordinary dividends of $17,306 can be paid in 2018 without the approval of the Department. The Company paid no dividends in 2017 , 2016 or 2015 . Regulatory Risk-Based Capital An insurance enterprise’s state of domicile imposes minimum risk-based capital requirements that were developed by the NAIC. The formulas for determining the amount of risk-based capital specify various weighting factors that are applied to financial balances or various levels of activity based on the perceived degree of risk. Regulatory compliance is determined by a ratio of an enterprise’s regulatory total adjusted capital to its authorized control level risk-based capital, as defined by the NAIC. Companies below specific trigger points or ratios are classified within certain levels, each of which requires specified corrective action. This ratio for the Company significantly exceeds required minimum thresholds as of December 31, 2017 and 2016 .

The Individual Annuities segment consists of variable, variable-indexed, fixed-indexed and fixed annuities, which are provided through independent distribution channels made up of independent and wholly-owned broker dealers, agents, and registered representatives. Revenues for the Company’s variable annuity products are primarily earned as management and expense fees charged on underlying account balances. Revenues for the Company’s fixed annuity products are primarily earned as net investment income on invested assets supporting fixed account balances, with profitability driven by the spread between net investment income earned and interest credited to account balances. The Company discontinued selling fixed-indexed and fixed annuity products and the block of business is in run off, however, in-force volumes are material and included within the Individual Annuities segment. The Other segment consists of closed blocks of Life, LTC, and Special Markets products.

Summary of Significant Accoun31

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Basis of Presentation	(a) Basis of Presentation The Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP).
Use of Estimates	(b) Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect reported amounts of assets and liabilities, including reporting or disclosure of contingent assets and liabilities as of December 31, 2017 and 2016 , and the reported amounts of revenues and expenses during the reporting period. Future events, including changes in mortality, morbidity, interest rates, capital markets, and asset valuations could cause actual results to differ from the estimates used within the Financial Statements. Such changes in estimates are recorded in the period they are determined.
Investment Products and Universal Life Business	(c) Investment Products and Universal Life Business Investment products consist primarily of fixed and variable annuity products. Premium receipts are reported as deposits to the contractholders’ accounts or an establishment of future policy benefit reserves. Premiums and policy fees, net in the Statements of Operations represent asset fees, cost of insurance charges, administrative fees, charges for guarantees on investment products, and surrender charges for investment products and universal life insurance, all of which is net of reinsurance. These fees have been earned and assessed against contractholders on a daily or monthly basis throughout the contract period and are recognized as revenue when assessed and earned. Amounts assessed that represent compensation to the Company for services to be provided in future periods are not earned in the period assessed. Such amounts are reported as unearned revenue, which include unearned revenue reserves (URR), and are recognized in operations over the period benefited using the same assumptions and factors used to amortize capitalized acquisition costs. Unearned revenue is reported in Unearned premiums on the Balance Sheets. Surrender charges are recognized upon surrender of a contract in accordance with contractual terms. Derivatives embedded in fixed-indexed, variable, and certain life products are recorded at fair value and changes in value are included in Change in fair value of annuity and life embedded derivatives in the Statements of Operations. Benefits consist of interest credited to contractholders’ accounts and claims incurred in excess of the contractholders’ account balance, net of reinsurance, and are included in Net interest credited to account values and Policyholder benefits, net of recoveries, respectively, within the Statements of Operations. The Company offers a variable-indexed annuity product that combines a separate account option with a general account option that is similar to a fixed-indexed annuity. The Company has elected the fair value option to account for the entire insurance contract liability and the variable investment option assets in the separate account. The insurance contracts’ reserves are reported in Account balances and future policy benefit reserves and the variable investment option assets within the separate account are reported in Equity securities, trading on the Balance Sheets. Assets backing the general account are primarily reported in Fixed-maturity securities, available-for-sale on the Balance Sheets. Electing the fair value option for an insurance contract liability requires that the Company account for that liability as a financial instrument at fair value through profit and loss and also requires that acquisition costs be recognized immediately in expense. See note 6 for further details regarding the valuation methodology of the variable-indexed annuity product.
Life and Accident and Health Insurance	(d) Life and Accident and Health Insurance Premiums on traditional life products are recognized as revenue over the premium-paying periods of the contracts when due from contractholders. Premium revenue generally exceeds expected policy benefits in the early years of the contracts and a reserve liability is established for costs and benefits that are expected to be paid in the later years of the contracts. Accident and health premiums are recognized as earned on a pro rata basis over the risk coverage periods. Benefits and expenses are recognized as incurred.
Investments	(e) Investments Fixed-Maturity Securities and Equity Securities The Company has portfolios of fixed-maturity securities classified as “available-for-sale.” Accordingly, these securities are carried at fair value, and related unrealized gains and losses are credited or charged directly to accumulated other comprehensive income (AOCI) in stockholder’s equity, net of tax and related shadow adjustments. The adjustments to deferred acquisition costs (DAC) and deferred sale inducements (DSI) represent the change in amortization that would have been required as a charge or credit to operations had such unrealized amounts been realized. The adjustment to reserves represents the increase or decrease in the reserve balance that would have been required as a charge or credit to operations had such unrealized amounts been realized. The Company has a portfolio of equity securities classified as "trading". These securities are comprised of variable investment option assets within the separate account that relate directly to the variable-indexed annuity product. See note 2(c) for further detail regarding the presentation of this portfolio. These securities are carried at fair value, and related unrealized gains and losses are reflected in Change in fair value of assets and liabilities within the Statements of Operations. Dividends are accrued on the date they are declared. The Company has portfolios of structured securities which include mortgage-backed securities and other asset-backed securities. Mortgage-backed securities are presented separately while other asset-backed securities are included within 'Corporate securities' within the the Notes to the Financial Statements. Structured securities are amortized using, among other assumptions, anticipated prepayments. Prepayment assumptions for structured securities are obtained from various external sources or internal estimates. The Company believes these assumptions are consistent with those a market participant would use. The Company recognizes income using a constant effective yield method based on prepayment assumptions and the estimated economic life of the securities. For all structured securities , when actual prepayments differ significantly from anticipated prepayments, the effective yield is recalculated to reflect actual payments to date and anticipated future payments retrospectively. Any resulting adjustment is included in Interest and similar income, net in the Statements of Operations. The fair value of fixed-maturity securities and equity securities is obtained from third-party pricing sources whenever possible. Management completes its own independent price verification (IPV) process, which ensures security pricing is obtained from a third-party source other than the sources used by the Company's internal and external investment managers. The IPV process supports the reasonableness of price overrides and challenges by the internal and external investment managers and reviews pricing for appropriateness. Results of the IPV process are reviewed by the Company’s Pricing Committee. The Company reviews the available-for-sale fixed-maturity investment portfolios to determine whether or not declines in fair value are other-than-temporary. In addition, the Company continually evaluates average amortized cost, fair value, credit quality, extent and duration of the decline, market analysis, current events, recent price declines, changes in risk-free interest rates, and likelihood of recovery in a reasonable period of time. Based on this evaluation, the Company determines whether fixed-income securities are considered other-than-temporarily impaired. When the fair value of a fixed-maturity security is less than its amortized cost, the Company assesses whether or not (i) it has the intent to sell the security or (ii) it is more likely than not that the Company will be required to sell the security before its anticipated recovery. The Company evaluates these factors to determine whether the Company or any of its internal and external investment managers have the intent to sell a security or a group of securities. The Company performs a cash flow projection for several years into the future to determine whether cash needs would require the sale of any securities in an unrealized loss position. If either of these conditions are met, the Company must recognize an other-than-temporary impairment (OTTI) for the difference between the investment’s amortized cost basis and its fair value through earnings. For securities that do not meet the above criteria and the Company does not expect to recover a security’s amortized cost basis, the security is also considered other-than-temporarily impaired. For these securities, the Company separates the total impairment into the credit loss component and the amount of the loss related to other factors. The amount of the total impairment related to credit loss is considered an OTTI and is recognized in Realized investment (losses) gains, net in the Statements of Operations. The amount of the total impairment related to other factors is recognized in other comprehensive income (OCI), net of impacts to DAC, DSI, reserves, and deferred income taxes. For available-for-sale securities that have recognized an OTTI through earnings, if through subsequent evaluation there is a significant increase in the cash flow expected, the difference between the amortized cost basis and the discounted cash flows expected to be collected is accreted as interest income. Subsequent increases and decreases not related to additional credit losses in the fair value of available-for-sale securities are included in the Statements of Comprehensive Income (Loss). The Company evaluates whether a credit loss exists by considering primarily the following factors: (a) the length of time and extent to which the fair value has been less than the amortized cost of the security; (b) changes in the financial condition, credit rating, and near-term prospects of the issuer; (c) whether the issuer is current on contractually obligated interest and principal payments; (d) changes in the financial condition of the security’s underlying collateral, if any; and (e) the payment structure of the security . The Company uses a probability-weighted cash flow model for fixed-maturity securities to determine the credit loss amount. This measurement is a quantitative and qualitative process that incorporates information received from third-party sources along with certain internal assumptions and significant judgments regarding the future performance of the security. The Company’s probability-weighted cash flow model involves assumptions including, but not limited to, various performance indicators, such as historical and projected default and recovery rates, credit ratings, and current delinquency rates. The Company provides a supplemental disclosure within the Statements of Operations that presents the total OTTI losses recognized in earnings during the period. The supplemental disclosure excludes subsequent increases and decrease in the fair value of these securities. Impairments in the value of securities held by the Company considered to be other-than-temporary are recorded as a reduction of the cost of the security, and a corresponding realized loss is recognized in the Statements of Operations. The Company adjusts DAC and DSI for impairments on securities, as discussed in their respective sections of this note. Short-Term Securities Short-term securities are comprised of fixed-maturity securities with an original maturity of twelve months or less and greater than three months when purchased. Short-term securities are carried at amortized cost, which approximates fair value due to their short-term nature. Policy Loans Policy loans are supported by the underlying cash value of the policies. Policy loans are carried at unpaid principal balances plus accrued interest income on the Balance Sheets. Variable Interest Entities In the normal course of business, the Company enters into relationships with various entities that are deemed to be variable interest entities. A variable interest entity (VIE) is an entity that either (1) has equity investors that lack certain essential characteristics of a controlling financial interest (including the ability to control activities of the entity, the obligation to absorb the entity’s expected losses, and the right to receive the entity’s expected residual returns) or (2) lacks sufficient equity to finance its own activities without financial support provided by other entities, which in turn would be expected to absorb at least some of the expected losses of the VIE. The Company consolidates a VIE if it is determined to be the primary beneficiary. Those entities which do not meet the requirements to be a VIE are voting interest entities (VOEs). The Company consolidates a VOE if it holds a voting interest that is greater than 50%.
Derivatives	(f) Derivatives The Company utilizes derivatives within certain actively managed investment portfolios. Within these portfolios, derivatives can be used for hedging, replication, and income generation only. The financial instruments are carried at fair value and the unrealized gains and losses are reflected in Change in fair value of assets and liabilities in the Statements of Operations. Futures and Options Contracts The Company provides benefits through certain life and annuity products which are linked to the fluctuation of various market indices, and certain variable annuity contracts that provide minimum guaranteed benefits. The Company has analyzed the characteristics of these benefits and has entered into over-the-counter (OTC) option contracts and exchange-traded futures contracts tied to an underlying index with similar characteristics with the objective to economically hedge these benefits. Management monitors in-force amounts and option and futures contract values to ensure satisfactory matching and to identify unsatisfactory mismatches. If actual persistency deviated, management would purchase or sell option and futures contracts as deemed appropriate or take other actions. The OTC option contracts are reported at fair value in Derivative assets and Derivative liabilities on the Balance Sheets. The fair value of the OTC options is derived internally and deemed by management to be reasonable via performing an IPV process. The process of deriving internal derivative prices requires the Company to calibrate Monte Carlo scenarios to actual market information. The calibrated scenarios are applied to derivative cash flow models to calculate fair value prices for the derivatives. Changes in unrealized gains and losses on the OTC option contracts and incremental gains and losses from expiring contracts are recorded within Change in fair value of assets and liabilities in the Statements of Operations. Futures contracts do not require an initial cash outlay, and the Company has agreed to daily net settlement based on movements of the representative index. Therefore, no asset or liability is recorded on the Balance Sheets. Gains and/or losses on futures contracts are included in Change in fair value of assets and liabilities in the Statements of Operations. Interest Rate Swaps and Total Return Swaps The Company utilizes interest rate swaps (IRS) and total return swaps (TRS) also to economically hedge market risks embedded in certain annuities . The IRS and TRS are reported at fair value in Derivative assets and Derivative liabilities on the Balance Sheets . The fair value of the IRS are derived using a third-party vendor software program and deemed by management to be reasonable. Centrally cleared IRS fair values are obtained from the exchange on which they were traded. The fair value of the TRS is based on counterparty pricing and deemed by management to be reasonable. The unrealized gains and losses as well as investment income and expenses on these derivatives are recorded in Change in fair value of assets and liabilities in the Statements of Operations.
Cash and Cash Equivalents	(g) Cash and Cash Equivalents Cash and cash equivalents include cash on hand, demand deposits, short-term government money market funds, overnight commercial paper, and highly liquid debt instruments purchased with an original maturity of three months or less. Due to the short-term nature of these investments, the carrying value is deemed to approximate fair value.
Receivables	(h) Receivables Receivable balances (contractual amount less allowance for doubtful accounts) are based on pertinent information available to management as of year-end, including the financial condition and creditworthiness of the parties underlying the receivables. Receivable balances are monitored and the allowance for doubtful accounts is maintained based on the nature of the receivables, and the Company’s assessment of the ability to collect . The allowance is estimated by aging the balances due from individual parties and generally setting up an allowance for any balances that are more than 90 days old.
Reinsurance	(i) Reinsurance The Company cedes business with other insurers. Reinsurance premium and benefits paid or provided are accounted for in a manner consistent with the basis used in accounting for original policies issued and the terms of the reinsurance contracts and are included in Premiums and policy fees, net, and Policyholder benefits, net of recoveries, respectively, in the Statements of Operations. Insurance liabilities are reported before the effects of reinsurance. Account balances and future policy benefit reserves and policy and contract claims covered under reinsurance contracts are recorded in Reinsurance and investment contract recoverables on the Balance Sheets. Amounts paid or deemed to have been paid for claims covered by reinsurance contracts are recorded as Receivables on the Balance Sheets. Reinsurance and investment contract recoverables are recognized in a manner consistent with the liabilities related to the underlying reinsured contracts. Amounts due to other insurers on assumed business are recorded as a reinsurance payable, and are included in Other liabilities on the Balance Sheets. A gain recognized when the Company enters into a coinsurance agreement with a third-party reinsurer is deferred and recorded in Other liabilities on the Balance Sheets. Such gains are amortized into operations over the revenue-producing period or the claims run-off period of the related reinsured policies. These amortized gains are recorded in Fee, commission, and other revenue in the Statements of Operations.
Deferred Acquisition Costs	(j) Deferred Acquisition Costs Acquisition costs consist of commissions and other incremental costs that are directly related to the successful acquisition of insurance contracts. Acquisition costs are deferred to the extent recoverable from future policy revenues and gross profits. However, acquisition costs associated with insurance contracts recorded under the fair value option are not deferred as guidance related to the fair value option requires that transaction costs are recorded immediately as an expense. For life and annuity products, with the exception of variable annuity contracts issued prior to 2010, acquisition costs are amortized in relation to the present value of expected future gross profits from investments and mortality, morbidity, and expense charges. For variable annuity contracts issued prior to 2010, acquisition costs are amortized in relation to the present value of estimated gross revenues from investments and mortality, morbidity, and expense charges. Acquisition costs for accident and health insurance policies are amortized over the lives of the policies in the same manner as premiums are earned. For traditional life and group life products, such costs are amortized over the projected earnings pattern of the related policies using the same actuarial assumptions used in computing future policy benefit reserves. DAC are reviewed for recoverability and loss recognition, at least annually, and adjusted when necessary. The evaluation is a two-step process where current policy year issues are evaluated for recoverability, and then in-force policies are evaluated for loss recognition. Before assessing recoverability and loss recognition, DAC are capped, if necessary, such that the balance cannot exceed the original capitalized costs plus interest. Changes in assumptions can have an impact on the amount of DAC reported for annuity and life insurance products and their related amortization patterns. In the event experience differs from assumptions or assumptions are revised, the Company is required to record an increase or decrease in DAC amortization expense, which is referred to as DAC unlocking. In general, increases in the estimated investment spreads and fees result in increased expected future profitability and may decrease the rate of DAC amortization, while increases in costs of product guarantees, and lapse/surrender and mortality assumptions reduce the expected future profitability of the underlying business and may increase the rate of DAC amortization. The Company formally evaluates the appropriateness of the best-estimate assumptions on an annual basis. If the economic environment or policyholder behavior changes quickly and substantially, assumptions will be reviewed more frequently to affirm best estimates. Any resulting DAC unlocking is reflected prospectively in Change in deferred acquisition costs, net in the Statements of Operations. Adjustments to DAC are made to reflect the corresponding impact on the present value of expected future gross profits and revenues from unrealized gains and losses on available-for-sale investments used to support policyholder liabilities (commonly known as shadow DAC). These adjustments are included in AOCI and are explained further in the Investments section of this note. Adjustments may also be made to DAC that correspond to deferred annuities and universal life products for investment activity, such as write-downs on other-than-temporarily impaired fixed-maturity securities and realized gains and losses. Management action may result in assumption changes in the DAC models, such as adjustments to future estimated gross profits (EGP) and estimated gross revenues used, as well as in-force management action such as crediting rate changes or index rate cap adjustments. See further discussion of DAC unlocking in note 9. The Company assesses internal replacements on insurance contracts to determine whether such modifications significantly change the contract terms. An internal replacement represents a modification in product benefits, features, rights, or coverages that occurs by the exchange of an in-force insurance contract for a new insurance contract, or by amendment, endorsement, or rider to a contract. If the modification substantially changes the contract, the remaining DAC on the original contract are immediately expensed and any new DAC on the replacement contract are deferred. If the contract modification does not substantially change the contract, DAC amortization on the original contract continues and any new acquisition costs associated with the modification are immediately expensed.
Deferred Sales Inducements	(k) Deferred Sales Inducements Sales inducements are product features that enhance the investment yield to the contractholder on the contract. The Company offers an immediate bonus on certain annuity contracts which increases the account value at inception. These annuity sales inducements are deferred when credited to contractholders. DSI are reported in Other assets on the Balance Sheets. They are amortized over the expected life of the contract in a manner similar to DAC and are reviewed annually for recoverability. DSI amortization is recorded in Policyholder benefits, net of recoveries within the Statements of Operations. Adjustments to DSI are made to reflect the estimated corresponding impact on the present value of expected future gross profits and revenues from unrealized gains and losses on available-for-sale investments used to support policyholder liabilities (commonly known as shadow DSI). These adjustments are included in AOCI and are explained further in the Investments section of this note. Adjustments may also be made to DSI for investment activity, such as write-downs on other-than-temporarily impaired fixed-maturity securities, and realized gains and losses. Management action may result in assumption changes in the DSI models, such as adjustments to future EGP used, as well as policyholder changes, such as credited rate changes.
Income Taxes	(l) Income Taxes The Company and the Company's parent, Allianz Life, file a consolidated federal income tax return with AZOA and many of its wholly-owned subsidiaries. The consolidated tax allocation agreement stipulates that each company participating in the return will bear its share of the tax liability pursuant to certain tax allocation elections under the Internal Revenue Code (IRC) and its related regulations and reimbursement will be in accordance with an intercompany tax reimbursement arrangement . The Company generally will be paid for the tax benefit on its losses and any other tax attributes to the extent it could have obtained a benefit against the Company's post-1990 separate return tax liability. The Company provides for federal income taxes based on amounts the Company believes it ultimately will owe. Inherent in the provision for federal income taxes are estimates regarding the deductibility of certain items and the realization of certain tax credits. In the event the ultimate deductibility of certain items or the realization of certain tax credits differs from estimates, the Company may be required to significantly change the provision for federal income taxes recorded on the Balance Sheets. Any such change could significantly affect the amounts reported within the Statements of Operations. Management uses best estimates to establish reserves based on current facts and circumstances regarding tax exposure items where the ultimate deductibility is open to interpretation. Quarterly, management evaluates the appropriateness of such reserves based on any new developments specific to their fact patterns. Information considered includes results of completed tax examinations, Technical Advice Memorandums, and other rulings issued by the Internal Revenue Service or the tax courts. The Company utilizes the asset and liability method of accounting for income tax. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized within operations in the period that includes the enactment date. Subsequent changes in deferred tax assets and liabilities are recognized in operations or OCI, depending on the nature of the underlying temporary difference. Valuation allowances are established when it is determined that it is more likely than not that the deferred tax asset will not be fully realized or that the related temporary differences will not reverse over time. See note 11 for further details.
Separate Account and Annuity Product Guarantees	(m) Separate Account and Annuity Product Guarantees The Company issues variable annuity contracts through its separate account for which investment income and investment gains and losses accrue directly to, and investment risk is borne by, the contractholder. The Company also issues variable-indexed annuity contracts to its customers. These products have investment options similar to fixed-indexed annuities, but allow contractholders to invest in a variety of variable separate account investment options. The Company recognizes gains or losses on transfers from the general account to the separate account at fair value to the extent of contractholder interests in the separate account, which are offset by changes in contractholder liabilities. The Company issues variable annuity and previously issued life contracts through its separate account where the Company provides certain contractual guarantees to the contractholder. These guarantees are in the form of a guaranteed minimum death benefit (GMDB), a guaranteed minimum income benefit (GMIB), a guaranteed minimum accumulation benefit (GMAB), and a guaranteed minimum withdrawal benefit (GMWB). The investments backing the guarantees are held in the general account. These guarantees provide for benefits that are payable to the contractholder in the event of death, annuitization, exercise of the living withdrawal benefit, or at specified dates during the accumulation period. Separate account assets supporting variable annuity contracts represent funds for which investment income and investment gains and losses accrue directly to contractholders. Each fund has specific investment objectives and the assets are carried at fair value. The assets of each account are legally segregated and are not subject to claims that arise out of any other business of the Company. Separate account assets and liabilities are reported as summary totals on the Balance Sheets. Amounts charged to the contractholders for mortality and contract maintenance are included in Premiums and policy fees, net in the Statements of Operations. Administrative and other services are included in Fee, commission, and other revenue in the Statements of Operations. These fees have been earned and assessed against contractholders on a daily or monthly basis throughout the contract period and are recognized as revenue when assessed and earned. Changes in GMDB and GMIB are calculated in accordance with the Financial Services – Insurance Topic of the Accounting Standards Codification (Codification) and are included in Policyholder benefits, net of recoveries in the Statements of Operations. GMAB and GMWB are considered to be embedded derivatives under the Derivatives and Hedging Topic of the Codification, and the changes in these embedded derivatives are included in Change in fair value of annuity and life embedded derivatives in the Statements of Operations. The GMDB net amount at risk is defined as the guaranteed amount that would be paid upon death, less the current accumulated contractholder account value. The GMIB net amount at risk is defined as the current amount that would be needed to fund expected future guaranteed payments less the current contractholder account value, assuming that all benefit selections occur as of the valuation date. The GMAB net amount at risk is defined as the current guaranteed value amount that would be added to the contracts less the current contractholder account value. The GMWB net amount at risk is defined as the current accumulated benefit base amount less the current contractholder account value. The GMDB provides a specified minimum return upon death. The survivor has the option to terminate the contract or continue it and have the death benefit paid into the contract. The Company’s GMDB options have the following features: • Return of Premium • Reset • Ratchet The GMIB is a living benefit that provides the contractholder with a guaranteed annuitization value. The GMIB features are: • Return of Premium • Rollup The GMDB and GMIB liabilities are determined each period by estimating the expected future claims in excess of the associated account balances. The Company regularly evaluates estimates used and adjusts the additional liability balance, with a related charge or credit to Policyholder benefits, net of recoveries in the Statements of Operations , if actual experience or other evidence suggests that earlier assumptions should be revised. The GMAB is a living benefit that provides the contractholder with a guaranteed value that was established at least five years prior at each contract anniversary. This benefit is first available at the fifth contract anniversary, seventh contract anniversary, or tenth contract anniversary depending on the type of contract. Depending on the contractholder’s selection at issue, this value may be either a return of premium or may reflect market gains, adjusted at least proportionately for withdrawals. The contractholder also has the option to reset this benefit. The GMWB is a living benefit that provides the contractholder with a guaranteed amount of income in the form of partial withdrawals. The benefit is payable provided the covered person is between the specified ages in the contract. The benefit is a fixed rate (depending on the age of the covered person) multiplied by the benefit base in the first year the benefit is taken and contract value in following years. The benefit does not decrease if the contract value decreases due to market losses. The benefit can decrease if the contract value is reduced by withdrawals. The benefit base used to calculate the initial benefit is the maximum of the contract value, the quarterly anniversary value, or the guaranteed annual increase of purchase payments (either simple or compound interest, depending on the contract). Additionally, there is a GMWB living benefit where the benefit is an initial payment percentage established at issue, based on issue age. For each year there is a year-over-year contract value increase, the payment percentage will increase by 1.0% (up to age 91). This payment percentage is applied against total purchase payments instead of a benefit base value. The GMAB and GMWB liabilities are determined each period as the difference between the present value of the expected future claims and the expected future profits. One result of this calculation is that these liabilities can be negative (contra liability). If the sum of the total embedded derivative balance is negative, the Company will reclassify the balance as an asset on the Balance Sheets. This methodology will also be applied to the fixed-indexed benefit. The Company regularly evaluates estimates used and adjusts the additional liability balance, with a related charge or credit to Change in fair value of annuity and life embedded derivatives in the Statements of Operations , if actual experience or other evidence suggests that earlier assumptions should be revised. GMAB cash flows are discounted using a rate equal to current month’s London Interbank Offered Rate (LIBOR) plus a Company specific spread. The expected life-contingent GMWB payments are discounted using a blend of short and long term rates to the date the account value is expected to be exhausted. These obligations and all cash flows are then discounted to the current date using LIBOR plus a Company specific spread. The Company has in-force fixed-indexed annuities with a GMWB as an optional rider. The GMWB has a roll-up feature. The net amount at risk is partially limited, because the contractholder account value has an annual credit that is floored at zero. Since the account value cannot decrease, in contrast to a variable annuity, the difference between the withdrawal value and the account value will not diverge to the degree that is possible in a variable annuity.
Account Balances and Future Policy Benefit Reserves	(n) Account Balances and Future Policy Benefit Reserves The Company establishes liabilities for amounts payable to policyholders associated with annuity, life insurance, and LTC policies sold. Policy and contract account balances for universal life products are carried at accumulated contract values. For fixed-indexed annuity products, the policyholder obligation is divided into two parts – one part representing the value of the underlying base contract (host contract); and the second part representing the fair value of the expected index benefit over the life of the contract. The host contract is accounted for as an interest-bearing debt instrument. The index benefit is valued at fair value using current capital market assumptions, such as market index and volatility, to estimate future index levels. The index benefit valuation is also dependent upon assumptions of future policyholder behavior. The Company must include provisions for the Company’s own credit risk and for risk that the Company’s assumptions about policyholder activity could differ from actual experience. The fair value determination of the index benefit is sensitive to the economic market and interest rate environment, as it is discounted at current market interest rates. There is volatility in this liability due to these external market sensitivities. Certain two-tier fixed annuity products provide additional benefits payable upon annuitization for period-certain and life-contingent payout options. An additional annuitization reserve is accrued using assumptions consistent with those used in estimating gross profits for purposes of amortizing DAC. Contract account balances for variable annuity products are carried at accumulated contract values. Future policy benefit reserves for any death and income benefits that may exceed the accumulated contract values are established using a range of economic scenarios and are accrued for using assumptions consistent with those used in estimating gross profits or gross revenues for purposes of amortizing DAC. Future policy benefit reserves for accumulation and withdrawal benefits that may exceed account values are established using capital market assumptions, such as market index and volatility, along with estimates of future contractholder behavior. Contract account balances for variable-indexed annuity products are measured at fair value, floored at the current contract value. The fair value measurement uses current capital market assumptions, such as market index and volatility, to estimate future index levels. The contract valuation is also dependent upon estimates of future contractholder behavior. The Company must include provisions for the Company’s own credit risk and for risk that the Company’s assumptions about contractholder activity could differ from actual experience. The fair value determination of the index benefit is sensitive to the economic market and interest rate environment, as it is discounted at current market interest rates. There is volatility in this liability due to these external market sensitivities. However, if the accumulated contract account value exceeds the calculated fair value, the Company records the contract account balances at their current contract value. Future policy benefit reserves on traditional life products are computed by the net level premium method based upon estimated future investment yield, mortality, and withdrawal assumptions, commensurate with the Company’s experience, modified as necessary to reflect anticipated trends, including possible unfavorable deviations. Most life reserve interest assumptions range from 2.3% to 6.0% . Future policy benefit reserves on LTC products are computed using a net level reserve method. Reserves are determined as the excess of the present value of future benefits over the present value of future net premiums and are based on best estimate assumptions at the time of issue for morbidity, mortality, lapse, and interest with provisions for adverse deviation. Most LTC reserve interest assumptions range from 5.0% to 6.0% . An additional LTC reserve has been established to provide for future expected losses that are anticipated to occur after a period of profits. The reserve accrual will be over the profit period and is based on best estimate assumptions as of the current accrual period without provisions for adverse deviation.
Policy and Contract Claims	(o) Policy and Contract Claims Policy and contract claims include the liability for claims reported but not yet paid, claims incurred but not yet reported (IBNR), and claim settlement expenses on the Company’s accident and health business. Actuarial reserve development methods are generally used in the determination of IBNR liabilities. In cases of limited experience or lack of credible claims data, loss ratios are used to determine an appropriate IBNR liability. Claim and IBNR liabilities of a short-term nature are not discounted, but those claim liabilities resulting from disability income or LTC benefits include interest and mortality discounting.
Prescribed and Permitted Statutory Accounting Practices	(p) Prescribed and Permitted Statutory Accounting Practices The Company is required to file annual statements with insurance regulatory authorities, which are prepared on an accounting basis permitted or prescribed by such authorities. Prescribed statutory accounting practices include state laws, regulations, and general administrative rules, as well as a variety of publications of the National Association of Insurance Commissioners (NAIC). Permitted statutory accounting practices encompass all accounting practices that are not prescribed; such practices differ from state to state, may differ from company to company within a state, and may change in the future. The Company does not have any permitted or prescribed practices in effect that had an impact on net income or statutory surplus as of December 31, 2017 .
Recently Issued Accounting Pronouncements - Adopted	(q) Recently Issued Accounting Pronouncements – Adopted In October 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-17, Consolidation: Interests Held through Related-Parties that are under Common Control, to require a reporting entity to include all of its direct variable interests in a VIE, and on a proportionate basis, its indirect variable interests in a VIE held through related parties, including related parties that are under common control with the reporting entity, when determining whether the reporting entity is the primary beneficiary of the VIE, and therefore required to consolidate the VIE. The amendments in this update are effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The amendments in this update do not have an impact on the Financial Statements. In March 2016, the FASB issued ASU 2016-06, Contingent Put and Call Options in Debt Instruments, to provide clarifying guidance regarding the assessment of whether contingent call or put options on debt instruments are clearly related to their debt hosts. The amendments in this update eliminate diversity in practice in assessing embedded contingent call and put options in debt instruments by requiring an entity to make the assessment solely with the four-step decision process. The amendments in this update are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments in this update do not have an impact on the Financial Statements.
Recently Issued Accounting Pronouncements - To Be Adopted	(r) Recently Issued Accounting Pronouncements – To Be Adopted The FASB issued the following updates as part of their comprehensive new revenue recognition standard: • ASU 2014-09, Revenue from Contracts with Customers. This update defines the new standard for recognizing revenue from contracts when goods and services are transferred to a customer in exchange for payment. The model requires 1) identifying contracts with a customer; 2) identifying separate performance obligations; 3) determining the transaction price; 4) allocating the transaction price to the separate performance obligations; and 5) recognizing revenue when (or as) the entity satisfies a performance obligation. The revenue recognition standard does not apply to financial instruments or to insurance contracts. However, the standard will require significantly more disclosures about items that are recorded under the new revenue recognition model. The amendments in this update are effective for fiscal years beginning after December 15, 2017. • ASU 2016-08, Revenue Recognition - Principal versus Agent (reporting revenue gross versus net). This update adds clarifications to the principal versus agent guidance contained within ASU 2014-09 and provides guidance to aid in the assessment of control. Under the new guidance, an entity that controls the specified good or services before it is transferred to a customer is considered a principal and will recognize revenue on a gross basis. The amendments in this update are effective concurrently with ASU 2014-09. • ASU 2016-12, Revenue Recognition - Narrow-scope Improvements and Practical Expedients. This update provides clarifying guidance impacting several areas of the new standard, including noncash consideration and assessing collectibility. The amendments in this update are effective concurrently with ASU 2014-09. • ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. This update makes various minor clarifications to the guidance issued in ASU 2014-09. The amendments in this update are effective concurrently with ASU 2014-09. The Company does not have significant sources of revenue outside insurance contracts and investments, which are specifically excluded from the scope of the new revenue recognition standard. Company revenue within the scope of the new standard includes fee and commission income, which under previous guidance requires revenue recognition when it is earned and realized/realizable including consideration of when it is fixed or determinable. Fee and commission income is recorded in Fee, commission, and other revenue in the Statements of Operations. Under the new standard, the Company will be required to recognize fee and commission income when the intermediary has satisfied its performance obligation (provision of placement services) and the customer has contractually agreed to the terms of the insurance policy so long as it is probable that the agreement will not be subject to reversal. While fee and commission income is not material to the Company’s overall revenue, this source of revenue was evaluated pursuant to the new revenue recognition standard and recognition has remained unchanged. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits stranded tax effects resulting from the passing of H.R.1, commonly referred to as the Tax Cuts and Jobs Act of 2017 (Tax Act of 2017), to be reclassified to retained earnings. The amendments in this update are effective for fiscal years and interim periods beginning after December 15, 2018, with early adoption permitted. Upon adoption, the Company expects the amendments in this update will decrease Retained earnings as of January 1, 2018 by approximately $2,279 with a corresponding increase to AOCI. In March 2017, the FASB issued ASU 2017-08, Premium Amortization on Purchased Callable Debt Securities. The amendments in this update shorten the amortization period for certain callable debt securities held at a premium. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The Company does not expect the amendments in this update to have a material impact on the Financial Statements upon adoption. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows: Restricted Cash, to require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash and restricted cash equivalents. The amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not expect the amendments in this update to have an impact on the Financial Statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes: Intra-Entity Transfers of Assets Other than Inventory, to require entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, rather than when it is sold externally. The amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not expect the amendments in this update to have an impact on the Financial Statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, to clarify or provide additional guidance regarding eight specific cash flow issues. These issues address the following topics: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; 3) contingent consideration payments made after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investees; 7) beneficial interests in securitization transactions; and 8) separately identifiable cash flows and application of the predominance principle. The amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not expect the amendments in this update to have a material impact on the Financial Statements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, to replace the existing incurred loss impairment model with a new methodology that reflects expected credit losses and requires the entity to consider more information to develop credit loss estimates. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted after December 15, 2018. The Company is currently assessing the impact of the amendments in this update. In February 2016, the FASB issued ASU 2016-02, Leases, to require that the lessee recognize a right-of-use asset and a lease liability for all leases. There continues to be a distinction between finance leases and operating leases; however, operating leases will now require that the lease assets and liabilities be recognized in the statement of financial position. Lessor accounting remains largely unchanged. The amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. The Company is currently assessing the impact of the amendments in this update. The Company does not expect the amendments in this update to have a material impact on the Financial Statements upon adoption. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, to make various targeted improvements to the accounting for financial instruments, especially equity investments. In particular, the amendments in this update provide improvements to recognition, measurement, presentation and disclosure guidance. The amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not expect the amendments in this update to have a material impact on the Financial Statements upon adoption.

[2]	No range is applicable due to only one security within classification.
[3]	The Company classifies realized and unrealized gains (losses) on Reserves at fair value as unrealized gains (losses) for purposes of disclosure in this table because the Company monitors Reserves at fair value as a whole unit and does not track realized gains (losses) on a contract-by-contract basis.
