Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	BUSINESS AND BASIS OF PRESENTATION Pruco Life Insurance Company (“Pruco Life”) is a wholly-owned subsidiary of The Prudential Insurance Company of America (“Prudential Insurance”), which in turn is a direct wholly-owned subsidiary of Prudential Financial, Inc. (“Prudential Financial”). Pruco Life is a stock life insurance company organized in 1971 under the laws of the State of Arizona. It is licensed to sell life insurance and annuities in the District of Columbia, Guam and in all states except New York, and sells such products primarily through affiliated and unaffiliated distributors. Pruco Life has one wholly-owned insurance subsidiary, Pruco Life Insurance Company of New Jersey (“PLNJ”) and had one indirect subsidiary formed in 2009 for the purpose of holding certain commercial mortgage loans and other investments, which ceased operations and was dissolved as of December 31, 2018. Pruco Life and its subsidiary are together referred to as the "Company", "we" or "our" and all financial information is shown on a consolidated basis. PLNJ is a stock life insurance company organized in 1982 under the laws of the state of New Jersey. It is licensed to sell life insurance and annuities in New Jersey and New York only. Basis of Presentation The Unaudited Interim Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted 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”). Intercompany balances and transactions have been eliminated. 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 Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. 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; amortization of deferred sales inducements ("DSI"); valuation of investments including derivatives and the recognition of other-than-temporary impairments (“OTTI”); future policy benefits including guarantees; reinsurance recoverables; 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. Out of Period Adjustment During the second quarter of 2019, the Company recorded an out of period adjustment resulting in a net increase of $11 million to "Income (loss) from operations before income taxes and equity in earnings of operating joint venture" for the three months ended June 30, 2019. This adjustment relates to investment income from equity method investments that should have been recorded during first quarter of 2019. Management has evaluated the impact of all out of period adjustments, both individually and in the aggregate, and concluded that they are not material to any current or previously reported quarterly or annual financial statements. Reclassifications Certain amounts in prior periods have been reclassified to conform to the current period presentation.
