Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	BUSINESS AND BASIS OF PRESENTATION Prudential Annuities Life Assurance Corporation (the “Company” or “PALAC”), with its principal offices in Shelton, Connecticut, is a wholly-owned subsidiary of Prudential Annuities, Inc. (“PAI”), which in turn is an indirect wholly-owned subsidiary of Prudential Financial, Inc. ("Prudential Financial"), a New Jersey corporation. Effective April 1, 2016, the Company reinsured the variable annuity base contracts, along with the living benefit guarantees, from Pruco Life Insurance Company ("Pruco Life"), excluding the Pruco Life Insurance Company of New Jersey ("PLNJ") business which was reinsured to The Prudential Insurance Company of America (“Prudential Insurance”), in each case under a coinsurance and modified coinsurance agreement. This reinsurance agreement covers new and in force business and excludes business reinsured externally. As of December 31, 2020, Pruco Life discontinued the sales of traditional variable annuities with guaranteed living benefit riders. The discontinuation has no impact on the reinsurance agreement between Pruco Life and the Company. In addition, the living benefit hedging program related to the living benefit guarantees as well as the product risks for retained and reinsured businesses are being managed within the Company and Prudential Insurance, as applicable. Effective July 1, 2021, Pruco Life recaptured the risks related to its business, as discussed above, that had previously been reinsured to the Company from April 1, 2016 through June 30, 2021. The recapture does not impact PLNJ, which will continue to reinsure its new and in force business to Prudential Insurance. The product risks related to the previously reinsured business that were being managed in the Company, were transferred to Pruco Life. In addition, the living benefit hedging program related to the previously reinsured living benefit riders will be managed within Pruco Life. The Company is engaged in a business that is highly competitive because of the large number of stock and mutual life insurance companies and other entities engaged in marketing long-term savings and retirement products, including insurance products, and individual and group annuities. Basis of Presentation The Unaudited Interim Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) on a basis consistent with reporting interim financial information in accordance with instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities and Exchange Commission (“SEC”). In the opinion of management, all adjustments necessary for a fair statement of the financial position and results of operations have been made. All such adjustments are of a normal, recurring nature. Interim results are not necessarily indicative of the results that may be expected for the full year. These financial statements should be read in conjunction with the Company’s Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates include those used in determining deferred policy acquisition costs ("DAC") and related amortization; policyholders' account balances related to the fair value of embedded derivative instruments associated with the index-linked features of certain annuity products; value of business acquired ("VOBA") and its amortization; amortization of deferred sales inducements ("DSI"); valuation of investments including derivatives, measurement of allowance for credit losses, and the recognition of other-than-temporary impairments (“OTTI”); future policy benefits including guarantees; provision for income taxes and valuation of deferred tax assets; and accruals for contingent liabilities, including estimates for losses in connection with unresolved legal and regulatory matters. COVID-19 Beginning in the first quarter of 2020, the outbreak of the novel coronavirus (“COVID-19”) resulted in extreme stress and disruption in the global economy and financial markets. While markets have rebounded, the pandemic has adversely impacted, and may continue to adversely impact, the Company's results of operations, financial condition and cash flows. Due to the highly uncertain nature of these conditions, it is not possible to estimate the ultimate impacts at this time. The risks may have manifested, and may continue to manifest, in the Company's financial statements in the areas of, among others, i) investments: increased risk of loss on our investments due to default or deterioration in credit quality or value; and ii) insurance liabilities and related balances: potential changes to assumptions regarding investment returns, mortality and policyholder behavior which are reflected in our insurance liabilities and certain related balances (e.g., DAC, VOBA, etc.). The Company cannot predict what impact the COVID-19 pandemic will ultimately have on its businesses. Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.
