Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1. Summary of Significant Accounting Policies Basis of Presentation Transamerica Advisors Life Insurance Company (“TALIC,” the “Registrant,” the “Company,” “we,” “our,” or “us” The Company is a life insurance company that conducts its business primarily in the annuity markets and, to a lesser extent, in the life insurance markets of the financial services industry. The Company is domiciled in the State of Arkansas and is currently licensed to sell insurance and annuities in forty-nine states, the District of Columbia, the U.S. Virgin Islands and Guam. The Company is currently subject to primary regulation by the Arkansas Insurance Department. Basis of Reporting The accompanying Financial Statements have been prepared in conformity with United States generally accepted accounting principles (“GAAP”). The Company also submits financial statements to insurance industry regulatory authorities, which are prepared on the basis of statutory accounting principles (“SAP”). The interim Financial Statements are unaudited; all adjustments (consisting of normal recurring accruals) necessary for a fair statement of the Financial Statements have been included. These unaudited Financial Statements should be read in conjunction with the audited Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. For a complete discussion of the Company’s 2016 Financial Statements and accounting policies, refer to the Company’s Annual Report on Form 10-K. The nature of the Company’s business is such that results of any interim period are not necessarily indicative of results for a full year. Accounting Estimates and Assumptions The preparation of financial statements in conformity to GAAP requires management to make estimates and assumptions affecting the reported amounts of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities. Those estimates are inherently subject to change and actual results could differ from those estimates. Included among the material (or potentially material) reported amounts and disclosures that require extensive use of estimates are: the fair value of certain investments (including derivatives), asset valuation allowances, deferred policy acquisition costs, deferred sales inducements, the value of business acquired, goodwill, policyholder liabilities, income taxes, and the potential effects of unresolved litigation matters. Subsequent Events The Financial Statements are adjusted to reflect events that occurred between the Balance Sheet date and the date when the Financial Statements are issued, provided they give evidence of conditions that existed at the Balance Sheet date. Events that are indicative of conditions that arose after the Balance Sheet date are disclosed, but do not result in an adjustment of the Financial Statements themselves. No subsequent events have been identified through November 14, 2017 that require adjustments to or disclosure in the Financial Statements.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 2. Fair Value of Financial Instruments Fair Value Measurements Accounting Standards Codification (“ASC”) 820 defines fair value, establishes a framework for measuring fair value, establishes a three-level fair value hierarchy based on the quality of inputs used to measure fair value and enhances disclosure requirements for fair value measurements. Fair Value Hierarchy The Company has categorized its financial instruments into the three-level hierarchy based on the priority of the inputs to the valuation technique. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure fair value fall within different levels of the hierarchy, the category level is based on the lowest priority level input that is significant to the fair value measurement of the instrument. Assets and liabilities recorded at fair value on the Balance Sheets are categorized as follows: Level 1 . Unadjusted quoted prices for identical assets or liabilities in an active market. Level 2 . Quoted prices in markets that are not active or inputs that are observable either directly or indirectly for substantially the full term of the asset or liability. Level 2 inputs include the following: a) Quoted prices for similar assets or liabilities in active markets b) Quoted prices for identical or similar assets or liabilities in non-active markets c) Inputs other than quoted market prices that are observable d) Inputs that are derived principally from or corroborated by observable market data through correlation or other means Level 3 . Prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Both observable and unobservable inputs may be used to determine the fair value of positions classified in Level 3. The circumstances for using unobservable measurements include those in which there is little, if any, market activity for the assets or liabilities. Therefore, the Company must make assumptions about inputs that a hypothetical market participant would use to value the assets and liabilities. The Company recognizes transfers between levels at the beginning of the quarter. The following tables present the Company’s hierarchy for its assets and liabilities measured at fair value on a recurring basis at September 30, 2017 and December 31, 2016: September 30, 2017 Level 1 Level 2 Level 3 Total Assets Fixed maturity available-for-sale ("AFS") securities (a) Corporate securities $ - $ 966,863 $ - $ 966,863 Asset-backed securities - 39,320 10,256 49,576 Commercial mortgage-backed securities - 74,060 - 74,060 Residential mortgage-backed securities - 114,011 - 114,011 Municipals - 882 - 882 Government and government agencies United States 354,407 - - 354,407 Foreign 1,460 24,641 - 26,101 Total fixed maturity AFS securities $ 355,867 $ 1,219,777 $ 10,256 $ 1,585,900 Equity AFS securities (a) Banking securities $ - $ 28,292 $ - $ 28,292 Industrial securities - 5,775 - 5,775 Total equity AFS securities $ - $ 34,067 $ - $ 34,067 Cash equivalents (b) $ - $ 322,028 $ - $ 322,028 Derivative assets (c) - 2,903 - 2,903 Fair value recoverable of ceded guaranteed minimum income benefits ("GMIB") embedded derivatives (d) - - 30,913 30,913 Investments measured at net asset value ("NAV") (e) - - - 5,796,212 Total assets $ 355,867 $ 1,578,775 $ 41,169 $ 7,772,023 Liabilities Future policy benefits (embedded derivatives only) (f) $ - $ - $ 41,578 $ 41,578 Derivative liabilities (c) - 1,001 - 1,001 Total liabilities $ - $ 1,001 $ 41,578 $ 42,579 December 31, 2016 Level 1 Level 2 Level 3 Total Assets Fixed maturity AFS securities (a) Corporate securities $ - $ 911,851 $ - $ 911,851 Asset-backed securities - 43,372 9,215 52,587 Commercial mortgage-backed securities - 76,513 - 76,513 Residential mortgage-backed securities - 96,177 - 96,177 Municipals - 856 - 856 Government and government agencies United States 341,379 - - 341,379 Foreign 1,480 6,194 - 7,674 Total fixed maturity AFS securities $ 342,859 $ 1,134,963 $ 9,215 $ 1,487,037 Equity AFS securities (a) Banking securities $ - $ 26,726 $ - $ 26,726 Industrial securities - 5,825 - 5,825 Total equity AFS securities $ - $ 32,551 $ - $ 32,551 Cash equivalents (b) $ - $ 265,538 $ - $ 265,538 Derivative assets (c) - 16,526 - 16,526 Fair value recoverable of ceded GMIB embedded derivatives (d) - - 48,166 48,166 Investments measured at NAV (e) - - - 5,730,860 Total assets $ 342,859 $ 1,449,578 $ 57,381 $ 7,580,678 Liabilities Future policy benefits (embedded derivatives only) (f) $ - $ - $ 55,143 $ 55,143 Derivative liabilities (c) - 15,165 - 15,165 Total liabilities $ - $ 15,165 $ 55,143 $ 70,308 (a) The fair values of debt securities are determined by management after taking into consideration several sources of data. When available, the Company uses quoted market prices in active markets to determine the fair value of its debt securities. The Company’s valuation policy utilizes a pricing hierarchy that dictates that publicly available prices are initially sought from indices and third party pricing services. In the event that pricing is not available from these sources, securities are submitted to brokers to obtain quotes. The majority of brokers’ quotes are non-binding. As part of the pricing process, the Company assesses the appropriateness of each quote (i.e., whether the quote is based on observable market transactions) to determine the most appropriate estimate of fair value. Lastly, securities are priced using internal cash flow modeling techniques. These valuation methodologies commonly use the following inputs: reported trades, bids, offers, issuer spreads, benchmark yields, estimated prepayment speeds, and/or estimated cash flows. Third-party pricing services and brokers will often determine prices using recently reported trades for identical or similar securities. The third-party pricing services and brokers make adjustments for the elapsed time from the trade date to the Balance Sheet date to take into account available market information. Lacking recently reported trades, third-party pricing services and brokers will use modeling techniques to determine a security price where expected future cash flows are developed based on the performance of the underlying collateral and discounted using an estimated market rate. Periodically, the Company performs an analysis of the inputs obtained from third-party pricing services and brokers to ensure that the inputs are reasonable and produce a reasonable estimate of fair value. The Company’s asset specialists and investment valuation specialists consider both qualitative and quantitative factors as part of this analysis. Several examples of analytical procedures performed include, but are not limited to, recent transactional activity for similar debt securities, review of pricing statistics and trends and consideration of recent relevant market events. Other controls and procedures over pricing received from indices, third-party pricing services, or brokers include validation checks, such as exception reports that highlight significant price changes, stale prices or un-priced securities. Following is additional discussion of the valuation methodologies for certain types of debt and equity securities: Corporate debt securities - Valuations of corporate debt securities are monitored and reviewed on a monthly basis. The pricing hierarchy is dependent on the possibility of corroboration of market prices when available. If no market prices are available, valuations are determined by a discounted cash flow methodology using an internally calculated yield. The yield is comprised of a credit spread over a given benchmark, taking into account liquidity risk for thinly traded securities. Residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”) and asset-backed securities (“ABS”) - Valuations of RMBS, CMBS and ABS are monitored and reviewed on a monthly basis. Valuations are based on a pricing hierarchy and, depending on the asset type, the pricing hierarchy consists of a waterfall that starts with making use of market prices from indices and follows with making use of third-party pricing services or brokers. The pricing hierarchy is dependent on the possibility of corroborating the market prices. If no market prices are available, the Company uses either internal models or another available pricing source to determine fair value. Significant inputs included in the internal models are generally determined based on relative value analyses, which incorporate comparisons to instruments with similar collateral and risk profiles. Market standard models may be used to model the specific collateral composition and cash flow structure of each transaction. The most significant unobservable input is the illiquidity premium, which is embedded in the discount rate. Government and government agencies - When available, the Company uses quoted market prices in active markets to determine the fair value of its government and government agencies’ investments. When the Company cannot make use of quoted market prices, market prices from indices or quotes from third-party pricing services or brokers are used. Equity securities – Valuations of equity securities are monitored and reviewed on a monthly basis. When available, the Company uses quoted market prices in active markets to determine the fair value of its equity investments. When the Company cannot make use of quoted market prices, quotes from a third-party vendor, broker, or custodian are used. (b) Cash equivalents are primarily valued at amortized cost, which approximates fair value. Operating cash is not included in the above table. (c) Level 2 derivatives include interest rate swaps, inflation swaps, variance swaps, total return swaps, credit default swaps, and options for which the Company utilized readily accessible quoted index levels and broker quotes . The fair value of exchange traded interest rate swaps is calculated based on the change in the underlying floating rate curve measured using the Overnight Index Swap at the reporting date, as compared to the fixed leg of the swap. The fair value of over-the-counter traded interest rate swaps is calculated based on the change in the underlying floating rate curve measured using the London Inter-Bank Offered Rate (“LIBOR”) at the reporting date, as compared to the fixed leg of the swap. The fair value of inflation swaps is calculated as the difference between the consumer price index (or related readily accessible quoted inflation index level) at the reporting date and the last reset date, multiplied by the notional value of the swap. The fair value of variance swaps is calculated as the difference between the estimated volatility of the underlying Standard & Poor’s 500 Composite Price Index (“S&P”) at maturity and the actual volatility of the underlying S&P at initiation (i.e., strike) multiplied by the notional value of the swap. Total return swaps are valued based on the change in the underlying equity index as of the last reset date. The fair value of equity options is calculated using the Black-Scholes model and market observable inputs for the underlying market price and volatility surface. Credit default swaps are valued using a discounted cash flow model where future premium payments and protection payments are corrected for the probability of default, which is modeled using an arbitrage free credit spread model. (d) The Company reinsures a portion of its variable annuity business that offers GMIB reinsurance. GMIB reinsurance contracts are treated as embedded derivatives since they contain payment provisions for net settlement and, therefore, are reported separately from the host contract. (e) Amounts are comprised of certain investments that are measured at fair value using the NAV per share (or its equivalent) as a practical expedient and have not been classified in the fair value hierarchy in accordance with ASC 820-10. These investments do not have lockup periods.

The liabilities for the contracts containing GMWB are treated as embedded derivatives, which are required to be reported separately from the host contract. The fair value of these guarantees is calculated as the present value of future expected payments to policyholders less the present value of assessed fees attributable to the guarantees. Given the complexity and long-term nature of the guarantees, their fair values are determined using stochastic techniques under a variety of market return, discount rate and actuarial assumptions. Since two of the assumptions are unobservable and are considered to be significant inputs to the liability valuation, the liability included in future policy benefits has been reflected within Level 3 of the fair value hierarchy. For the nine months ended September 30, 2017 and twelve months ended December 31, 2016, there were no The following table provides a summary of the change in the fair value of the Company's Level 3 fixed maturity AFS securities at September 30, 2017 and December 31, 2016: Nine Months Ended September 30, 2017 Twelve Months Ended December 31, 2016 Fixed Maturity AFS Fixed Maturity AFS Securities Securities Balance at beginning of period (a) $ 9,215 $ 6,666 Change in unrealized gains (losses) (b) 222 (243 ) Purchases 4,001 2,792 Sales (2,189 ) (326 ) Transfers into Level 3 3,000 2,113 Transfers out of Level 3 (3,994 ) (1,954 ) Net realized investment gains (c) 1 167 Balance at end of period (a) $ 10,256 $ 9,215 (a) Recorded as a component of fixed maturity AFS securities on the Balance Sheets. (b) Recorded as a component of other comprehensive income (loss) (“OCI”) in net unrealized holding gains (losses) on AFS securities arising during the period. (c) Recorded as a component of net realized investment gains (losses) on securities in the Statements of Income (Loss). In certain circumstances, the Company will obtain non-binding broker quotes from brokers to assist in the determination of fair value. If those quotes can be corroborated by other market-observable data, the investments will be classified as Level 2 investments. If not, the investments are classified as Level 3 due to the unobservable nature of the brokers’ valuation processes. The primary drivers for the increase in Level 3 fixed maturity securities at September 30, 2017 is due to the transfer of an asset-backed security from Level 2 to a Level 3 due to the unavailability of market-observable data (Level 2). The Company's Level 3 assets consist of GMIB reinsurance and Level 3 liabilities consist of provisions for GMWB and SALB. The fair value of these assets and liabilities is calculated as the present value of future expected payments to policyholders less the present value of assessed fees attributable to the guarantees. Given the complexity and long-term nature of these guarantees, which are unlike instruments available in financial markets, their fair values are determined using stochastic techniques under a variety of market return scenarios. A variety of factors are considered, including expected market rates of return, equity and interest rate volatility, credit spread, correlations of market returns, discount rates and actuarial assumptions. Changes in the Company’s credit spread and volatility assumptions have an inverse effect on the GMIB reinsurance assets. An increase (decrease) in credit spread of GMWB and SALB in isolation would result in a lower (higher) fair value liability measurement and an increase (decrease) in volatility in isolation would result in a higher (lower) fair value liability measurement. The expected market rates of return are based on risk-free rates, such as the current LIBOR forward curve. The credit spread, which is a significant unobservable input, is set by using the credit default swap (“CDS”) spreads of a reference portfolio of life insurance companies, adjusted to reflect the subordination of senior debt holders at the holding company level to the position of policyholders at the operating company level (who have priority in payments to other creditors). The credit spread was For equity volatility, the Company uses a term structure assumption with market-based implied volatility inputs for the first five years and a long-term forward rate assumption of 25%-30% The following table provides a summary of the changes in the fair value of the Company’s Level 3 liabilities (assets) at September 30, 2017 and December 31, 2016: Nine Months Ended Twelve Months Ended September 30, 2017 December 31, 2016 GMIB GMIB GMWB Reinsurance SALB GMWB Reinsurance SALB Balance at beginning of period (a) $ 54,414 $ (48,166 ) $ 729 $ 60,618 $ (61,426 ) $ 511 Changes in interest rates (b) 5,241 (2,620 ) - (4,179 ) 2,262 - Changes in equity markets (b) (16,099 ) 19,892 - (5,988 ) 12,560 218 Other (b) (2,707 ) (19 ) - 3,963 (1,562 ) - Balance at end of period (a) $ 40,849 $ (30,913 ) $ 729 $ 54,414 $ (48,166 ) $ 729 (a) GMWB and SALB are recorded as a component of future policy benefits on the Balance Sheets and GMIB reinsurance is recorded as recoverable of ceded GMIB embedded derivatives, at fair value on the Balance Sheets. (b) Recorded as a component of policy benefits in the Statements of Income (Loss). For the nine months ended September 30, 2017, the change in the fair value of the GMWB and GMIB reinsurance guarantees was primarily driven by changes in equity market performance, interest rates, and annual model assumption updates. The fair value of the GMWB decreased primarily due to favorable equity market returns, along with changes in annual model assumption updates for improved mortality, partially offset by low interest rates and a decrease in own credit spread. The increase to the GMIB reinsurance guarantees was driven primarily by favorable equity market returns, slightly offset by low interest rates.

Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Unrealized Losses on Fixed Maturity and Equity Securities The Company’s investments in fixed maturity and equity securities classified as AFS are carried at estimated fair value with unrealized gains and losses included in stockholder’s equity as a component of AOCI, net of taxes. The estimated fair value and gross unrealized losses and OTTI related to fixed maturity and equity AFS securities aggregated by length of time that individual securities have been in a continuous unrealized loss position at September 30, 2017 and December 31, 2016 were as follows: September 30, 2017 Gross Estimated Unrealized Fair Amortized Losses and Value Cost/Cost OTTI (a) Less than or equal to six months Fixed maturity AFS securities Corporate securities $ 117,891 $ 118,457 $ (566 ) Asset-backed securities 10,250 10,282 (32 ) Commercial mortgage-backed securities 27,104 27,393 (289 ) Residential mortgage-backed securities 2,092 2,127 (35 ) Government and government agencies United States 6,594 6,622 (28 ) Equity securities 5,775 5,791 (16 ) Total fixed maturity and equity AFS securities $ 169,706 $ 170,672 $ (966 ) Greater than six months but less than or equal to one year Fixed maturity AFS securities Corporate securities $ 1,219 $ 1,394 $ (175 ) Asset-backed securities 1,557 1,605 (48 ) Commercial mortgage-backed securities 995 1,021 (26 ) Foreign 3,742 3,812 (70 ) Total fixed maturity and equity AFS securities $ 7,513 $ 7,832 $ (319 ) Greater than one year Fixed maturity AFS securities Corporate securities $ 7,836 $ 8,489 $ (653 ) Asset-backed securities 7,986 8,102 (116 ) Residential mortgage-backed securities 8 8 - Municipals 882 906 (24 ) Total fixed maturity and equity AFS securities $ 16,712 $ 17,505 $ (793 ) Total fixed maturity and equity AFS securities $ 193,931 $ 196,009 $ (2,078 ) December 31, 2016 Gross Estimated Unrealized Fair Amortized Losses and Value Cost/Cost OTTI (a) Less than or equal to six months Fixed maturity AFS securities Corporate securities $ 64,992 $ 66,625 $ (1,633 ) Asset-backed securities 30,729 31,253 (524 ) Commercial mortgage-backed securities 30,698 31,285 (587 ) Residential mortgage-backed securities 54,987 55,690 (703 ) Equity securities - banking securities 8,213 8,500 (287 ) Total fixed maturity and equity AFS securities $ 189,619 $ 193,353 $ (3,734 ) Greater than six months but less than or equal to one year Fixed maturity AFS securities Corporate securities $ 4,522 $ 4,863 $ (341 ) Asset-backed securities 879 1,000 (121 ) Commercial mortgage-backed securities 1,010 1,012 (2 ) Residential mortgage-backed securities 212 229 (17 ) Total fixed maturity and equity AFS securities $ 6,623 $ 7,104 $ (481 ) Greater than one year Fixed maturity AFS securities Corporate securities $ 19,541 $ 21,131 $ (1,590 ) Asset-backed securities 7,978 8,182 (204 ) Residential mortgage-backed securities 2,122 2,172 (50 ) Municipals 856 909 (53 ) Equity AFS securities - banking securities 1,615 1,796 (181 ) Total fixed maturity and equity AFS securities $ 32,112 $ 34,190 $ (2,078 ) Total fixed maturity and equity AFS securities $ 228,354 $ 234,647 $ (6,293 ) (a) Subsequent unrealized gains (losses) on OTTI securities are included in Net unrealized OTTI on securities in the Statements of Comprehensive Income (Loss). The total number of securities in an unrealized loss position was 67 367 The fair value, gross unrealized losses/the portion of OTTI recognized in OCI and the number of securities with fair value declining below amortized cost by between 20% and 40% by length of time that securities have been in a continuous unrealized loss position were as follows at September 30, 2017 and December 31, 2016: September 30, 2017 December 31, 2016 Estimated Gross Unrealized Number of Estimated Gross Unrealized Number of Fair Value Losses/OTTI (a) Securities Fair Value Losses/OTTI (a) Securities Decline 20% - 40% Held longer than one year $ 1,375 $ (614 ) 1 $ 1,375 $ (614 ) 1 Total $ 1,375 $ (614 ) 1 $ 1,375 $ (614 ) 1 (a) Subsequent unrealized gains (losses) on OTTI securities are included in Net unrealized OTTI on securities in the Statements of Comprehensive Income (Loss). Unrealized gains (losses) incurred during the first nine months of 2017 and twelve months of 2016 were primarily due to price fluctuations resulting from changes in interest rates and credit spreads. If the Company has the intent to sell or it is more likely than not that the Company will be required to sell these securities prior to the anticipated recovery of the amortized cost, securities are written down to fair value. If cash flow models indicate a credit event will impact future cash flows, the security is impaired to discounted cash flows. For fixed maturity AFS securities, the Company does not intend to sell them, nor is it more likely than not that the Company will be required to sell them before the recovery of its amortized cost basis, and the Company expects to recover the entire cost basis of the debt securities. In making the other-than-temporary impairment assessment, the Company also considered all available information relevant to the collectability of the security, including information about past events, current conditions, and reasonable and supportable forecasts, when developing the estimate of cash flows expected to be collected. Therefore, the Company determined that these fixed maturity AFS securities were not other-than-temporarily impaired. The components of net unrealized gains (losses) and OTTI included in AOCI, net of taxes, at September 30, 2017 and December 31, 2016 were as follows: September 30, December 31, 2017 2016 Assets Fixed maturity AFS securities $ 128,769 $ 103,250 Equity AFS securities 2,803 1,287 Cash flow hedges 348 (1,224 ) Value of business acquired (31,369 ) (26,630 ) $ 100,551 $ 76,683 Liabilities Income taxes - deferred $ (21,333 ) $ (21,333 ) Stockholder's Equity Accumulated other comprehensive income, net of taxes $ 79,218 $ 55,350 Mortgage Loans on Real Estate Mortgage loans on real estate consist entirely of mortgages on commercial real estate. Prepayment premiums are collected when borrowers elect to prepay their debt prior to the stated maturity. There 0 in prepayment premiums collected during the three and nine months ended September 30, 2017. no The fair values of mortgage loans on real estate are estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and/or similar remaining maturities. The estimated fair value of the mortgages on commercial real estate at September 30, 2017 and December 31, 2016 was $ 26,203 Loans are considered impaired when it is probable that, based upon current information and events, the Company will be unable to collect all amounts due under the contractual terms of the loan agreement. A valuation allowance is established when a loan is determined to be impaired for the excess carrying value of the loan over its estimated collateral value. There were no The commercial mortgages are geographically diversified throughout the United States with the largest concentrations in Florida California, Utah, and Minnesota, 82% The credit quality of commercial mortgage loans at September 30, 2017 and December 31, 2016 was as follows: September 30, December 31, Commercial 2017 2016 AAA - AA $ 8,358 $ 43,047 A 16,846 55,269 BBB - 17,970 Total mortgage loans on real estate $ 25,204 $ 116,286 Less: allowance for credit losses (10 ) (78 ) Total mortgage loans on real estate, net $ 25,194 $ 116,208 The credit quality of the commercial mortgage loans was determined based on an internal credit rating model that assigns a letter rating to each mortgage loan in the portfolio as an indicator of the quality of the mortgage loan. The internal credit rating model was designed based on a rating agency methodology, then modified for credit risk associated with the Company’s mortgage lending process, taking into account such factors as projected future cash flows, net operating income, and collateral value. The model produces a rating score and an associated letter rating that is intended to align with S&P Global Rating Services (“S&P GRS”) ratings as closely as possible. Information supporting the risk rating process is updated at least annually. While mortgage loans with a lower rating carry a higher risk of loss, an adequate allowance for credit losses has been established to cover those risks.

At September 30, 2017, the before-tax deferred net gains (losses) on derivatives recorded in AOCI that are expected to be reclassified to the Statements of Income (Loss) during the next twelve months are ($911). This expectation is based on the anticipated interest payments on the hedged investments in Treasury Inflation Protection Securities that will occur over the next twelve months, at which time the Company will recognize the deferred gains (losses) as an adjustment to interest income over the term of the investment cash flows. In addition, in order to trade futures, the Company is required to post collateral to an exchange (sometimes referred to as margin). The fair value of collateral posted in relation to the futures margin was $2,374 and $5,276 at September 30, 2017 and December 31, 2016, respectively. Offsetting of Derivative Instruments The Company has derivative instruments that are subject to master netting agreements. These agreements include provisions to setoff positions with the same counterparties in the event of default by one of the parties. The following table presents the offsetting of derivative assets and liabilities at September 30, 2017 and December 31, 2016: September 30, 2017 December 31, 2016 Derivatives Subject to a Master Netting Arrangement or a Similar Right to Offset Assets Liabilities Assets Liabilities Gross estimated fair value of derivatives: OTC - Bilateral $ 15,380 $ 10,220 $ 37,344 $ 32,832 OTC - Cleared 1,435 2,968 1,678 4,477 Total gross estimated fair value of derivatives $ 16,815 $ 13,188 $ 39,022 $ 37,309 Amounts offset on the Balance Sheets Gross estimated fair value of derivatives: (1) OTC - Bilateral $ (9,378 ) $ (9,378 ) $ (18,014 ) $ (18,014 ) OTC - Cleared (1,435 ) (1,435 ) (1,678 ) (1,678 ) Cash collateral: (2), (3) OTC - Bilateral (3,099 ) - (2,804 ) - OTC - Cleared - (1,374 ) - (2,452 ) Estimated fair value of derivatives presented on the Balance Sheets $ 2,903 $ 1,001 $ 16,526 $ 15,165 Gross amounts not offset on the Balance Sheets: Securities collateral: (4) OTC - Bilateral $ (2,027 ) $ (623 ) $ (15,222 ) $ (14,249 ) Net amount after application of master netting agreements and collateral $ 876 $ 378 $ 1,304 $ 916 (1) Estimated fair value of derivatives is limited to the amount that is subject to set-off. (2) The amount of cash collateral offset in the table above is limited to the net estimated fair value of derivatives after application of netting agreements. Cash collateral received for over-the-counter ("OTC") OTC-Bilateral and OTC-Cleared derivatives is included in cash and cash equivalents, short-term investments, or fixed maturity securities, and the obligation to return it, beyond what is already being setoff, is included in payables for collateral under securities loaned, reverse repurchase agreements and derivatives. At September 30, 2017, the Company received $2,088 (3) The receivable for the return of cash collateral provided to the counterparty, beyond what is being setoff, is included in other assets. The amount reported in the table above does not include initial margin on exchange-traded and OTC-Cleared derivatives. At September 30, 2017 and December 31, 2016, the Company had no excess cash collateral provided to counterparties that was excluded from the table due to the foregoing limitation. (4) Securities collateral received or pledged by the Company is held in separate custodial accounts and is not recorded on the Balance Sheets. The amount of securities collateral offset in the table above is limited to the net estimated fair value of derivatives after application of netting agreements and cash collateral. At September 30, 2017 and December 31, 2016, the Company received excess securities collateral with an estimated fair value of $2,040 1,629 There were no Net Investment Income (Loss) Net investment income (loss) by source for the three and nine months ended September 30, 2017 and 2016 was as follows: Three Months Ended Nine Months Ended September 30, September 30, Net investment income (loss) 2017 2016 2017 2016 Fixed maturity AFS securities $ 15,621 $ 17,098 $ 46,289 $ 51,326 Equity AFS securities 517 418 1,357 1,421 Limited partnerships 1,070 1,574 3,013 (1,057 ) Mortgage loans on real estate 1,509 1,330 4,372 3,798 Policy loans on insurance contracts 8,285 8,555 24,739 25,545 Derivatives 1,602 1,547 4,876 5,316 Cash and cash equivalents 922 647 1,829 1,662 Other 93 18 236 233 Gross investment income $ 29,619 $ 31,187 $ 86,711 $ 88,244 Less investment expenses (2,192 ) (1,963 ) (4,923 ) (4,954 ) Net investment income (loss) $ 27,427 $ 29,224 $ 81,788 $ 83,290 Realized Investment Gains (Losses) The Company considers fair value at the date of sale to be equal to the proceeds received.

Variable Contracts Containing Guaranteed Benefits	Note 5. Variable Contracts Containing Guaranteed Benefits The Company has issued variable annuity contracts in which the Company may have contractually guaranteed to the contract owner a guaranteed minimum death benefit (“GMDB”) and/or an optional guaranteed living benefit provision. The living benefit provisions offered by the Company included a GMIB and a GMWB. Information regarding the general characteristics of each guaranteed benefit type is provided below: • In general, contracts containing GMDB provisions provide a death benefit equal to the greater of the GMDB or the contract value. Depending on the type of contract, the GMDB may equal: (1) contract deposits accumulated at a specified interest rate, (2) the contract value on specified contract anniversaries, (3) the return of contract deposits, or (4) some combination of these benefits. Each benefit type is reduced for contract withdrawals. • In general, contracts containing GMIB provisions provide the option to receive a guaranteed future income stream upon annuitization. There is a waiting period of ten years from contract issue that must elapse before the GMIB provision can be exercised. • Contracts containing GMWB provisions provide the contract owner the ability to withdraw minimum annual payments regardless of the impact of market performance on the contract owner’s account value. In general, withdrawal percentages are based on the contract owner’s age at the time of the first withdrawal. The Company records liabilities for contracts containing a GMDB, GMIB and GMWB as a component of future policy benefits on the Balance Sheets and changes in the liabilities are included as a component of policy benefits in the Statements of Income (Loss). The changes in the variable annuity GMDB, GMIB and GMWB liabilities for the three and nine months ended September 30, 2017 and 2016 were as follows: Three Months Ended Nine Months Ended September 30, September 30, GMDB 2017 2016 2017 2016 Guaranteed benefits incurred $ 5,534 $ 6,429 $ 17,199 $ 19,295 Guaranteed benefits paid (4,783 ) (3,060 ) (16,208 ) (16,357 ) Unlocking (9,741 ) (22,768 ) (26,201 ) (17,928 ) Total $ (8,990 ) $ (19,399 ) $ (25,210 ) $ (14,990 ) Three Months Ended Nine Months Ended September 30, September 30, GMIB 2017 2016 2017 2016 Guaranteed benefits incurred $ 2,649 $ 3,648 $ 8,452 $ 10,413 Guaranteed benefits paid (270 ) (300 ) (2,288 ) (1,706 ) Unlocking (6,100 ) (8,195 ) (24,551 ) (3,015 ) Total $ (3,721 ) $ (4,847 ) $ (18,387 ) $ 5,692 Three Months Ended Nine Months Ended September 30, September 30, GMWB 2017 2016 2017 2016 Change in fair value reserves (7,910 ) (7,159 ) (13,565 ) 16,713 Total $ (7,910 ) $ (7,159 ) $ (13,565 ) $ 16,713

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Note 6. Income Taxes The effective tax rate was not meaningful for the nine months ended September 30, 2017 and 2016. Differences between the effective rate and the U.S. statutory rate of 35% principally were the result of dividend received deductions (“DRD”) on the Separate Accounts, the valuation allowance on net operating loss (“NOL”) carryforwards and unrecognized tax benefits. The Company provides for deferred income taxes resulting from temporary differences that arise from recording certain transactions in different years for income tax reporting purposes than for financial reporting purposes. The asset and liability method requires that deferred taxes be adjusted to reflect the tax rates at which future taxable amounts will be settled or realized. The Company provides for federal income taxes based on amounts it believes it will ultimately owe. Inherent in the provision for federal income taxes are estimates regarding the realization of certain tax deductions and credits. The income tax expense (benefit) for the three and nine months ended September 30, 2017 and 2016 was $0 and $575, respectively. There was no income tax expense (benefit) for the three and nine months ended September 30, 2016. The income tax asset (liability) consists of the following at September 30, 2017 and December 31, 2016: September 30, December 31, 2017 2016 Current state income tax asset (liability) $ 1 $ 1 Deferred state income tax asset (liability) - 575 Net income tax asset (liability) $ 1 $ 576 At September 30, 2017 and December 31, 2016, the Company had a tax valuation allowance for deferred tax assets of $126,480 and $154,440, respectively (this includes losses that are anticipated to be used in the consolidated group to reflect the income statement impact of the losses that would not be used if filing separately). In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that all or some of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets depends on generation of future taxable income during the periods in which those temporary differences are deductible. Management considers the scheduled reversal of deferred tax liabilities, projected taxable income, and tax-planning strategies in making the assessment. The Company has analyzed all material tax positions under the guidance of ASC 740, Income Taxes, related to the accounting for uncertainty in income tax, and determined there were tax benefits of $4,395 (gross $12,559) and The components of the change in the unrecognized tax benefits were as follows at September 30, 2017 and December 31, 2016: September 30, December 31, 2017 2016 Balance at beginning of period $ 4,391 $ 3,404 Additions for tax positions of prior years 4 987 Balance at end of period $ 4,395 $ 4,391 At September 30, 2017 and December 31, 2016, the Company had a NOL carry forward for federal income tax purposes of $554,908 (net of the ASC 740 reduction of $12,559) and $627,860 (net of the ASC 740 reduction of $12,547), respectively, with a carry forward period of 15 years that expires at various dates between 2023 and 2031. At both September 30, 2017 and December 31, 2016, the Company had a capital loss carry forward of $84 for federal income tax purposes with a carry forward period of five years that will expire in 2018. At September 30, 2017 and December 31, 2016, the Company had a foreign tax credit carry forward of $9,853 and $9,776, respectively, with a carry forward period of 10 years that will expire at various dates up to 2027. Also, the Company has an Alternative Minimum Tax credit carry forward for federal income tax purposes of $4,216 at both September 30, 2017 and December 31, 2016, with an indefinite carry forward period. The Company classifies interest and penalties related to income taxes as interest expense and penalty expense, respectively. The Company recognized interest expense (income) of ($5) and $54 for the three and nine months ended September 30, 2017, respectively. The Company recognized interest expense (income) of $44 and $107 for the three and nine months ended September 30, 2016, respectively. The Company recognized penalty expense of $1 and $1 in its Financial Statements for the three and nine months ended September 30, 2017, respectively. The Company did not recognize any penalties in its Financial Statements for the three and nine months ended September 30, 2016, respectively. The total interest payable balance recognized at September 30, 2017 and December 31, 2016 was $215 and $161, respectively. The Company records taxes on a separate company basis. For federal income tax purposes, the Company joins in a consolidated income tax return filing with its direct parent, TA Corp, and other affiliated companies. The method of allocation between the companies is subject to a written tax allocation agreement. Under the terms of the agreement, taxes are payable to or receivable from TA Corp in amounts that would result had the Company filed a separate tax return with taxing authorities. Any tax differences between the Company’s separately calculated provision and cash flows attributable to benefits from consolidation have been recognized as capital contributions from TA Corp. At September 30, 2017 and December 31, 2016, the Company recognized capital contributions from (distributions to) TA Corp in connection with the tax allocation agreement in the amount of ($35,720) and ($13,381), respectively. Intercompany income tax balances are settled within thirty days of payment to or filing with the Internal Revenue Service. The Company filed a separate federal income tax return for the years 2008 through 2012. The Company was part of the consolidated tax return for 2013 through 2016. An examination by the Internal Revenue Service is in progress for the years 2011 through 2013. The Company believes that there are adequate defenses against or sufficient provisions established related to any open or contested tax positions.

Reinsurance Disclosures [Abstract]
Reinsurance	Note 9. Reinsurance In the normal course of business, the Company seeks to limit its exposure to loss on any single insured life and to recover a portion of benefits paid by ceding mortality risk to other insurance enterprises or reinsurers under indemnity reinsurance agreements, primarily quota share coverage and coinsurance agreements. The maximum amount of mortality risk retained by the Company is approximately $1,000 on single and joint life policies. At September 30, 2017, the Company had a reinsurance receivable of $200 and reinsurance payable of $195. At December 31, 2016, the Company had a reinsurance receivable of $166 and reinsurance payable of $203. Indemnity reinsurance agreements do not relieve the Company from its obligations to contract owners. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company regularly evaluates the financial condition of its reinsurers so as to minimize its exposure to significant losses from reinsurer insolvencies. The Company determined after this evaluation that no reserve was required. In addition, the Company seeks to limit its exposure to guaranteed benefit features contained in certain variable annuity contracts. Specifically, the Company reinsures certain GMIB and GMDB provisions to the extent reinsurance capacity is available in the marketplace. The percentage of variable annuity contract account values containing GMIB provisions that were reinsured was 33% and 34% at September 30, 2017 and December 31, 2016. The percentage of account values for variable annuity contracts containing GMDB provisions that were reinsured was 4% at both September 30, 2017 and December 31, 2016.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 11. Commitments and Contingencies State insurance laws generally require that all life insurers who are licensed to transact business within a state become members of the state's life insurance guaranty association. These associations have been established for the protection of contract owners from loss (within specified limits) as a result of the insolvency of an insurer. At the time insolvency occurs, the guaranty association assesses the remaining members of the association an amount sufficient to satisfy the insolvent insurer's contract owner obligations (within specified limits). The Company has utilized public information to estimate the future assessments it will incur as a result of life insurance company insolvencies. At both September 30, 2017 and December 31, 2016, the Company’s estimated liability for future guaranty fund assessments was $140. If future insolvencies occur, the Company’s estimated liability may not be sufficient to fund these insolvencies and the estimated liability may need to be adjusted. The Company regularly monitors public information regarding insurer insolvencies and adjusts its estimated liability as appropriate. Several states allow companies to take a credit on their premium tax returns for assessments paid to state guaranty associations to cover the obligations of insolvent insurers. The Company has a receivable for future premium tax deductions of $3,756 and $4,012 at September 30, 2017 and December 31, 2016, respectively. Legal and regulatory proceedings are subject to inherent uncertainties, and future events could change management's assessment of the probability or estimated amount of potential losses from pending or threatened proceedings. Based on available information, it is the opinion of management that the ultimate resolution of pending or threatened legal and regulatory proceedings, other than claims settlement expenses, both individually and in the aggregate, will not result in losses above any related accruals that will have a material adverse effect on the Company's financial position or liquidity at September 30, 2017. If management believes that, based on available information, it is at least reasonably possible that a material loss (or additional material loss in excess of any accrual) will be incurred in connection with any legal or regulatory proceedings, other than claims settlement expenses, the Company discloses an estimate of the possible loss or range of loss, either individually or in the aggregate, as appropriate, if such an estimate can be made, or discloses that an estimate cannot be made. Based on the Company's assessment at September 30, 2017, no such disclosures were considered necessary.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Transamerica Advisors Life Insurance Company (“TALIC,” the “Registrant,” the “Company,” “we,” “our,” or “us” The Company is a life insurance company that conducts its business primarily in the annuity markets and, to a lesser extent, in the life insurance markets of the financial services industry. The Company is domiciled in the State of Arkansas and is currently licensed to sell insurance and annuities in forty-nine states, the District of Columbia, the U.S. Virgin Islands and Guam. The Company is currently subject to primary regulation by the Arkansas Insurance Department.
Basis of Reporting	Basis of Reporting The accompanying Financial Statements have been prepared in conformity with United States generally accepted accounting principles (“GAAP”). The Company also submits financial statements to insurance industry regulatory authorities, which are prepared on the basis of statutory accounting principles (“SAP”). The interim Financial Statements are unaudited; all adjustments (consisting of normal recurring accruals) necessary for a fair statement of the Financial Statements have been included. These unaudited Financial Statements should be read in conjunction with the audited Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. For a complete discussion of the Company’s 2016 Financial Statements and accounting policies, refer to the Company’s Annual Report on Form 10-K. The nature of the Company’s business is such that results of any interim period are not necessarily indicative of results for a full year.
Accounting Estimates and Assumptions	Accounting Estimates and Assumptions The preparation of financial statements in conformity to GAAP requires management to make estimates and assumptions affecting the reported amounts of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities. Those estimates are inherently subject to change and actual results could differ from those estimates. Included among the material (or potentially material) reported amounts and disclosures that require extensive use of estimates are: the fair value of certain investments (including derivatives), asset valuation allowances, deferred policy acquisition costs, deferred sales inducements, the value of business acquired, goodwill, policyholder liabilities, income taxes, and the potential effects of unresolved litigation matters.
Subsequent Events	Subsequent Events The Financial Statements are adjusted to reflect events that occurred between the Balance Sheet date and the date when the Financial Statements are issued, provided they give evidence of conditions that existed at the Balance Sheet date. Events that are indicative of conditions that arose after the Balance Sheet date are disclosed, but do not result in an adjustment of the Financial Statements themselves. No subsequent events have been identified through November 14, 2017 that require adjustments to or disclosure in the Financial Statements.

When available, the Company uses quoted market prices in active markets to determine the fair value of its debt securities. The Company’s valuation policy utilizes a pricing hierarchy that dictates that publicly available prices are initially sought from indices and third party pricing services. In the event that pricing is not available from these sources, securities are submitted to brokers to obtain quotes. The majority of brokers’ quotes are non-binding. As part of the pricing process, the Company assesses the appropriateness of each quote (i.e., whether the quote is based on observable market transactions) to determine the most appropriate estimate of fair value. Lastly, securities are priced using internal cash flow modeling techniques. These valuation methodologies commonly use the following inputs: reported trades, bids, offers, issuer spreads, benchmark yields, estimated prepayment speeds, and/or estimated cash flows. Third-party pricing services and brokers will often determine prices using recently reported trades for identical or similar securities. The third-party pricing services and brokers make adjustments for the elapsed time from the trade date to the Balance Sheet date to take into account available market information. Lacking recently reported trades, third-party pricing services and brokers will use modeling techniques to determine a security price where expected future cash flows are developed based on the performance of the underlying collateral and discounted using an estimated market rate. Periodically, the Company performs an analysis of the inputs obtained from third-party pricing services and brokers to ensure that the inputs are reasonable and produce a reasonable estimate of fair value. The Company’s asset specialists and investment valuation specialists consider both qualitative and quantitative factors as part of this analysis. Several examples of analytical procedures performed include, but are not limited to, recent transactional activity for similar debt securities, review of pricing statistics and trends and consideration of recent relevant market events. Other controls and procedures over pricing received from indices, third-party pricing services, or brokers include validation checks, such as exception reports that highlight significant price changes, stale prices or un-priced securities. Following is additional discussion of the valuation methodologies for certain types of debt and equity securities: Corporate debt securities - Valuations of corporate debt securities are monitored and reviewed on a monthly basis. The pricing hierarchy is dependent on the possibility of corroboration of market prices when available. If no market prices are available, valuations are determined by a discounted cash flow methodology using an internally calculated yield. The yield is comprised of a credit spread over a given benchmark, taking into account liquidity risk for thinly traded securities. Residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”) and asset-backed securities (“ABS”) - Valuations of RMBS, CMBS and ABS are monitored and reviewed on a monthly basis. Valuations are based on a pricing hierarchy and, depending on the asset type, the pricing hierarchy consists of a waterfall that starts with making use of market prices from indices and follows with making use of third-party pricing services or brokers. The pricing hierarchy is dependent on the possibility of corroborating the market prices. If no market prices are available, the Company uses either internal models or another available pricing source to determine fair value. Significant inputs included in the internal models are generally determined based on relative value analyses, which incorporate comparisons to instruments with similar collateral and risk profiles. Market standard models may be used to model the specific collateral composition and cash flow structure of each transaction. The most significant unobservable input is the illiquidity premium, which is embedded in the discount rate. Government and government agencies - When available, the Company uses quoted market prices in active markets to determine the fair value of its government and government agencies’ investments. When the Company cannot make use of quoted market prices, market prices from indices or quotes from third-party pricing services or brokers are used. Equity securities – Valuations of equity securities are monitored and reviewed on a monthly basis. When available, the Company uses quoted market prices in active markets to determine the fair value of its equity investments. When the Company cannot make use of quoted market prices, quotes from a third-party vendor, broker, or custodian are used. (b) Cash equivalents are primarily valued at amortized cost, which approximates fair value. Operating cash is not included in the above table. (c) Level 2 derivatives include interest rate swaps, inflation swaps, variance swaps, total return swaps, credit default swaps, and options for which the Company utilized readily accessible quoted index levels and broker quotes . The fair value of exchange traded interest rate swaps is calculated based on the change in the underlying floating rate curve measured using the Overnight Index Swap at the reporting date, as compared to the fixed leg of the swap. The fair value of over-the-counter traded interest rate swaps is calculated based on the change in the underlying floating rate curve measured using the London Inter-Bank Offered Rate (“LIBOR”) at the reporting date, as compared to the fixed leg of the swap. The fair value of inflation swaps is calculated as the difference between the consumer price index (or related readily accessible quoted inflation index level) at the reporting date and the last reset date, multiplied by the notional value of the swap. The fair value of variance swaps is calculated as the difference between the estimated volatility of the underlying Standard & Poor’s 500 Composite Price Index (“S&P”) at maturity and the actual volatility of the underlying S&P at initiation (i.e., strike) multiplied by the notional value of the swap. Total return swaps are valued based on the change in the underlying equity index as of the last reset date. The fair value of equity options is calculated using the Black-Scholes model and market observable inputs for the underlying market price and volatility surface. Credit default swaps are valued using a discounted cash flow model where future premium payments and protection payments are corrected for the probability of default, which is modeled using an arbitrage free credit spread model. (d) The Company reinsures a portion of its variable annuity business that offers GMIB reinsurance. GMIB reinsurance contracts are treated as embedded derivatives since they contain payment provisions for net settlement and, therefore, are reported separately from the host contract. (e) Amounts are comprised of certain investments that are measured at fair value using the NAV per share (or its equivalent) as a practical expedient and have not been classified in the fair value hierarchy in accordance with ASC 820-10. These investments do not have lockup periods.

The liabilities for the contracts containing GMWB are treated as embedded derivatives, which are required to be reported separately from the host contract. The fair value of these guarantees is calculated as the present value of future expected payments to policyholders less the present value of assessed fees attributable to the guarantees. Given the complexity and long-term nature of the guarantees, their fair values are determined using stochastic techniques under a variety of market return, discount rate and actuarial assumptions. Since two of the assumptions are unobservable and are considered to be significant inputs to the liability valuation, the liability included in future policy benefits has been reflected within Level 3 of the fair value hierarchy.

[1]	The fair values of debt securities are determined by management after taking into consideration several sources of data. When available, the Company uses quoted market prices in active markets to determine the fair value of its debt securities. The Company’s valuation policy utilizes a pricing hierarchy that dictates that publicly available prices are initially sought from indices and third party pricing services. In the event that pricing is not available from these sources, securities are submitted to brokers to obtain quotes. The majority of brokers’ quotes are non-binding. As part of the pricing process, the Company assesses the appropriateness of each quote (i.e., whether the quote is based on observable market transactions) to determine the most appropriate estimate of fair value. Lastly, securities are priced using internal cash flow modeling techniques. These valuation methodologies commonly use the following inputs: reported trades, bids, offers, issuer spreads, benchmark yields, estimated prepayment speeds, and/or estimated cash flows. Third-party pricing services and brokers will often determine prices using recently reported trades for identical or similar securities. The third-party pricing services and brokers make adjustments for the elapsed time from the trade date to the Balance Sheet date to take into account available market information. Lacking recently reported trades, third-party pricing services and brokers will use modeling techniques to determine a security price where expected future cash flows are developed based on the performance of the underlying collateral and discounted using an estimated market rate. Periodically, the Company performs an analysis of the inputs obtained from third-party pricing services and brokers to ensure that the inputs are reasonable and produce a reasonable estimate of fair value. The Company’s asset specialists and investment valuation specialists consider both qualitative and quantitative factors as part of this analysis. Several examples of analytical procedures performed include, but are not limited to, recent transactional activity for similar debt securities, review of pricing statistics and trends and consideration of recent relevant market events. Other controls and procedures over pricing received from indices, third-party pricing services, or brokers include validation checks, such as exception reports that highlight significant price changes, stale prices or un-priced securities. Following is additional discussion of the valuation methodologies for certain types of debt and equity securities: Corporate debt securities - Valuations of corporate debt securities are monitored and reviewed on a monthly basis. The pricing hierarchy is dependent on the possibility of corroboration of market prices when available. If no market prices are available, valuations are determined by a discounted cash flow methodology using an internally calculated yield. The yield is comprised of a credit spread over a given benchmark, taking into account liquidity risk for thinly traded securities. Residential mortgage-backed securities (“RMBS”), commercial mortgage-backed securities (“CMBS”) and asset-backed securities (“ABS”) - Valuations of RMBS, CMBS and ABS are monitored and reviewed on a monthly basis. Valuations are based on a pricing hierarchy and, depending on the asset type, the pricing hierarchy consists of a waterfall that starts with making use of market prices from indices and follows with making use of third-party pricing services or brokers. The pricing hierarchy is dependent on the possibility of corroborating the market prices. If no market prices are available, the Company uses either internal models or another available pricing source to determine fair value. Significant inputs included in the internal models are generally determined based on relative value analyses, which incorporate comparisons to instruments with similar collateral and risk profiles. Market standard models may be used to model the specific collateral composition and cash flow structure of each transaction. The most significant unobservable input is the illiquidity premium, which is embedded in the discount rate. Government and government agencies - When available, the Company uses quoted market prices in active markets to determine the fair value of its government and government agencies’ investments. When the Company cannot make use of quoted market prices, market prices from indices or quotes from third-party pricing services or brokers are used. Equity securities – Valuations of equity securities are monitored and reviewed on a monthly basis. When available, the Company uses quoted market prices in active markets to determine the fair value of its equity investments. When the Company cannot make use of quoted market prices, quotes from a third-party vendor, broker, or custodian are used.
[2]	Cash equivalents are primarily valued at amortized cost, which approximates fair value. Operating cash is not included in the above table.
[3]	Level 2 derivatives include interest rate swaps, inflation swaps, variance swaps, total return swaps, credit default swaps, and options for which the Company utilized readily accessible quoted index levels and broker quotes. The fair value of exchange traded interest rate swaps is calculated based on the change in the underlying floating rate curve measured using the Overnight Index Swap at the reporting date, as compared to the fixed leg of the swap. The fair value of over-the-counter traded interest rate swaps is calculated based on the change in the underlying floating rate curve measured using the London Inter-Bank Offered Rate (“LIBOR”) at the reporting date, as compared to the fixed leg of the swap. The fair value of inflation swaps is calculated as the difference between the consumer price index (or related readily accessible quoted inflation index level) at the reporting date and the last reset date, multiplied by the notional value of the swap. The fair value of variance swaps is calculated as the difference between the estimated volatility of the underlying Standard & Poor’s 500 Composite Price Index (“S&P”) at maturity and the actual volatility of the underlying S&P at initiation (i.e., strike) multiplied by the notional value of the swap. Total return swaps are valued based on the change in the underlying equity index as of the last reset date. The fair value of equity options is calculated using the Black-Scholes model and market observable inputs for the underlying market price and volatility surface. Credit default swaps are valued using a discounted cash flow model where future premium payments and protection payments are corrected for the probability of default, which is modeled using an arbitrage free credit spread model.
[4]	The Company reinsures a portion of its variable annuity business that offers GMIB reinsurance. GMIB reinsurance contracts are treated as embedded derivatives since they contain payment provisions for net settlement and, therefore, are reported separately from the host contract.
[5]	Amounts are comprised of certain investments that are measured at fair value using the NAV per share (or its equivalent) as a practical expedient and have not been classified in the fair value hierarchy in accordance with ASC 820-10. These investments do not have lockup periods.
[6]	The Company recognizes liabilities for contracts containing guaranteed minimum withdrawal benefits ("GMWB") and stand-alone living benefits ("SALB"), which are reported at fair value. The liabilities for the contracts containing GMWB are treated as embedded derivatives, which are required to be reported separately from the host contract. The fair value of these guarantees is calculated as the present value of future expected payments to policyholders less the present value of assessed fees attributable to the guarantees. Given the complexity and long-term nature of the guarantees, their fair values are determined using stochastic techniques under a variety of market return, discount rate and actuarial assumptions. Since two of the assumptions are unobservable and are considered to be significant inputs to the liability valuation, the liability included in future policy benefits has been reflected within Level 3 of the fair value hierarchy.
