Business and Basis of Presentation [Abstract]
Business and Basis of Presentation	1.    BUSINESS AND BASIS OF PRESENTATION
	Prudential Financial, Inc. (“Prudential Financial”) and its subsidiaries (collectively, “Prudential” or the “Company” or “PFI”) provide a wide range of insurance, investment management, and other financial products and services to both individual and institutional customers throughout the United States and in many other countries. Principal products and services provided include life insurance, annuities, retirement-related services, mutual funds, and investment management.
	From December 18, 2001, the date of demutualization, through December 31, 2014, the Company organized its principal operations into the Financial Services Businesses and the Closed Block Business, and had two classes of common stock outstanding. The Common Stock, which is publicly traded (NYSE:PRU), reflected the performance of the Financial Services Businesses, while the Class B Stock, which was issued through a private placement and did not trade on any exchange, reflected the performance of the Closed Block Business.
	On January 2, 2015, Prudential Financial repurchased and cancelled all of the shares of the Class B Stock (the “Class B Repurchase”). As a result, the Company no longer organizes its principal operations into the Financial Services Businesses and the Closed Block Business. The Company's principal operations are comprised of four divisions: the U.S. Retirement Solutions and Investment Management division, the U.S. Individual Life and Group Insurance division, the International Insurance division and the Closed Block division. The Company's Corporate and Other operations include corporate items and initiatives that are not allocated to business segments, businesses that are not sufficiently material to warrant separate disclosure and businesses that have been or will be divested, excluding the Closed Block division.
	The Closed Block division includes the Company's in force participating insurance and annuity products and corresponding assets that are used for the payment of benefits and policyholders' dividends on these products (the “Closed Block”), as well as certain related assets and liabilities. In connection with demutualization, the Company ceased offering these participating products (see Note 6). The Closed Block division is accounted for as a divested business that is reported separately from the divested businesses that are included in the Company's Corporate and Other operations.
	Basis of Presentation
	As a result of the Class B Repurchase and resulting elimination of the separation of the Financial Services Businesses and the Closed Block Business, these Unaudited Interim Consolidated Financial Statements refer to the divisions and segments of the Company that formerly comprised the Financial Services Businesses as “PFI excluding Closed Block division” and refer to the operations that were formerly included in the Closed Block Business as the “Closed Block division,” except as otherwise noted. Closed Block Business results were associated with the Company's Class B Stock for periods prior to January 1, 2015.
	The Unaudited Interim Consolidated Financial Statements include the accounts of Prudential Financial, entities over which the Company exercises control, including majority-owned subsidiaries and minority-owned entities such as limited partnerships in which the Company is the general partner, and variable interest entities in which the Company is considered the primary beneficiary. See Note 5 for more information on the Company's consolidated variable interest entities. 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, 2014.
	The Company's Gibraltar Life Insurance Company, Ltd. (“Gibraltar Life”) consolidated operations use a November 30 fiscal year end for purposes of inclusion in the Company's Consolidated Financial Statements; therefore, the Unaudited Interim Consolidated Financial Statements as of March 31, 2015, include the assets and liabilities of Gibraltar Life and its results of operations as of, and for the three months ended, February 28, 2015, respectively.
	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; value of business acquired (“VOBA”) and its amortization; amortization of sales inducements; measurement of goodwill and any related impairment; valuation of investments including derivatives and the recognition of other-than-temporary impairments; future policy benefits including guarantees; pension and other postretirement benefits; provision for income taxes and valuation of deferred tax assets; and reserves for contingent liabilities, including reserves for losses in connection with unresolved legal matters.
	Reclassifications
	Certain amounts in prior periods have been reclassified to conform to the current period presentation.

Significant Accounting Policies and Pronouncements	2. SIGNIFICANT ACCOUNTING POLICIES AND PRONOUNCEMENTS
	This section supplements, and should be read in conjunction with, Note 2 to the Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014.
	Earnings Per Share
	As discussed in Note 1, from demutualization through December 31, 2014, the Company had two separate classes of common stock. Basic earnings per share for those periods was computed by dividing available income attributable to each of the two groups of common shareholders by the respective weighted average number of common shares outstanding for the period. Diluted earnings per share included the effect of all dilutive potential common shares that were outstanding during the period.
	As a result of the Class B Repurchase, earnings per share of Common Stock for the three months ended March 31, 2015 reflects the consolidated earnings of Prudential Financial. Basic earnings per share is computed by dividing available income attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share includes the effect of all dilutive potential common shares that were outstanding during the period. See Note 8 for additional information.
	Adoption of New Accounting Pronouncements
	In January 2014, the Financial Accounting Standards Board (“FASB”) issued updated guidance regarding investments in flow-through limited liability entities that manage or invest in affordable housing projects that qualify for the low-income housing tax credit. Under the guidance, an entity is permitted to make an accounting policy election to amortize the initial cost of its investment in proportion to the tax credits and other tax benefits received and recognize the net investment performance in the statement of operations as a component of income tax expense (benefit) if certain conditions are met. The new guidance became effective for annual periods and interim reporting periods within those annual periods that began after December 15, 2014. The Company did not elect the proportional amortization method under this guidance.
	In January 2014, the FASB issued updated guidance for troubled debt restructurings clarifying when an in substance repossession or foreclosure occurs, and when a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan. The new guidance became effective for annual periods and interim periods within those annual periods that began after December 15, 2014, and was applied prospectively. Adoption of the guidance did not have a significant effect on the Company's consolidated financial position, results of operations or financial statement disclosures.
	In April 2014, the FASB issued updated guidance that changes the criteria for reporting discontinued operations and introduces new disclosures. The new guidance became effective for new disposals and new classifications of disposal groups as held for sale that occur within annual periods that began on or after December 15, 2014, and interim periods within those annual periods. Adoption of the guidance did not have a significant effect on the Company's consolidated financial position, results of operations or financial statement disclosures.
	In August 2014, the FASB issued guidance requiring that mortgage loans be derecognized and that a separate other receivable be recognized upon foreclosure if certain conditions are met. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The new guidance became effective for annual periods and interim periods within those annual periods that began after December 15, 2014, and was applied prospectively. Adoption of the guidance did not have a significant effect on the Company's consolidated financial position, results of operations or financial statement disclosures.
	Future Adoption of New Accounting Pronouncements
	In May 2014, the FASB issued updated guidance on accounting for revenue recognition. The guidance is based on the core principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The guidance also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from cost incurred to obtain or fulfill a contract. Revenue recognition for insurance contracts is explicitly scoped out of the guidance. The new guidance is effective for annual periods and interim periods within those annual periods, beginning after December 15, 2016, and must be applied using one of two retrospective application methods. Early adoption is not permitted. The Company is currently assessing the impact of the guidance on the Company's consolidated financial position, results of operations and financial statement disclosures.
	In August 2014, the FASB issued updated guidance for measuring the financial assets and the financial liabilities of a consolidated collateralized financing entity. Under the guidance, an entity within scope is permitted to measure both the financial assets and financial liabilities of a consolidated collateralized financing entity based on either the fair value of the financial assets or the financial liabilities, whichever is more observable. If elected, the guidance will eliminate the measurement difference that exists when both are measured at fair value. The new guidance is effective for annual periods and interim reporting periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted, and can be elected for modified retrospective or full retrospective adoption. The Company is currently assessing the impact of the guidance on the Company's consolidated financial position, results of operations and financial statement disclosures.
	In February 2015, the FASB issued updated guidance that changes the rules regarding consolidation. The pronouncement eliminates specialized guidance for limited partnerships and similar legal entities, and removes the indefinite deferral for certain investment funds. The new guidance is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, with early adoption permitted. The Company is currently assessing the impact of the guidance on the Company's consolidated financial position, results of operations and financial statement disclosures.
	In April 2015, the FASB issued guidance that simplifies presentation of debt issuance costs. The pronouncement requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The new guidance is effective for periods beginning after December 15, 2015, with early adoption permitted, and it must be applied retrospectively. The Company is currently assessing the impact of the guidance on the Company's financial statement disclosures.

Excludes the portion of other-than-temporary impairments recorded in “Other comprehensive income (loss),” representing any difference between the fair value of the impaired debt security and the net present value of its projected future cash flows at the time of impairment.
As discussed in Note 2 to the Company's Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2014, a portion of certain other-than-temporary impairment (“OTTI”) losses on fixed maturity securities are recognized in “Other comprehensive income (loss)” (“OCI”). For these securities, the net amount recognized in earnings (“credit loss impairments”) represents the difference between the amortized cost of the security and the net present value of its projected future cash flows discounted at the effective interest rate implicit in the debt security prior to impairment. Any remaining difference between the fair value and amortized cost is recognized in OCI. The following table sets forth the amount of pre-tax credit loss impairments on fixed maturity securities held by the Company as of the dates indicated, for which a portion of the OTTI loss was recognized in OCI, and the corresponding changes in such amounts.

Concentrations of Financial Instruments
The Company monitors its concentrations of financial instruments on an ongoing basis, and mitigates credit risk by maintaining a diversified investment portfolio which limits exposure to any one issuer.
As of both March 31, 2015 and December 31, 2014, the Company's exposure to concentrations of credit risk of single issuers greater than 10% of the Company's stockholders' equity included securities of the U.S. government, certain U.S. government agencies and certain securities guaranteed by the U.S. government, as well as the securities disclosed below.

The gross unrealized losses on fixed maturity securities at March 31, 2015 and December 31, 2014, are composed of $1,185 million and $1,156 million related to high or highest quality securities based on the National Association of Insurance Commissioners (“NAIC”) or equivalent rating and $248 million and $200 million, related to other than high or highest quality securities based on NAIC or equivalent rating, respectively. At March 31, 2015, the $546 million of gross unrealized losses of twelve months or more were concentrated in the energy, utility and basic industry sectors of the Company's corporate securities. At December 31, 2014, the $901 million of gross unrealized losses of twelve months or more were concentrated in the energy, consumer non-cyclical and utility sectors of the Company's corporate securities. In accordance with its policy described in Note 2 to the Company's Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2014, the Company concluded that an adjustment to earnings for other-than-temporary impairments for these securities was not warranted at March 31, 2015 or December 31, 2014. These conclusions are based on a detailed analysis of the underlying credit and cash flows on each security. The gross unrealized losses are primarily attributable to foreign currency exchange rate movements and general credit spread widening. At March 31, 2015, the Company does not intend to sell the securities and it is not more likely than not that the Company will be required to sell the securities before the anticipated recovery of its remaining amortized cost basis.
At March 31, 2015, $17 million of the gross unrealized losses on equity securities represented declines in value of greater than 20%, $14 million of which had been in that position for less than six months. At December 31, 2014, $13 million of the gross unrealized losses on equity securities represented declines in value of greater than 20%, all of which had been in that position for less than six months. In accordance with its policy described in Note 2 to the Company's Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2014, the Company concluded that an adjustment for other-than-temporary impairments for these equity securities was not warranted at March 31, 2015 or December 31, 2014.

Variable Interest Entities [Abstract]
Variable Interest Entities	5. VARIABLE INTEREST ENTITIES
	In the normal course of its activities, the Company enters into relationships with various special-purpose entities and other entities that are deemed to be variable interest entities (“VIEs”). A 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.
	If the Company determines that it is the VIE's “primary beneficiary” it consolidates the VIE. There are currently two models for determining whether or not the Company is the “primary beneficiary” of a VIE. The first (the “Investment Company Model”) relates to those VIEs that have the characteristics of an investment company and for which certain other conditions are true. These conditions are that (1) the Company does not have the implicit or explicit obligation to fund losses of the VIE and (2) the VIE is not a securitization entity, asset-backed financing entity or an entity that was formerly considered a qualified special-purpose entity. In this model the Company is the primary beneficiary if it stands to absorb a majority of the VIE's expected losses or to receive a majority of the VIE's expected residual returns.
	For all other VIEs, the Company is the primary beneficiary if the Company has (1) the power to direct the activities of the VIE that most significantly impact the economic performance of the entity and (2) the obligation to absorb losses of the entity that could be potentially significant to the VIE or the right to receive benefits from the entity that could be potentially significant.
	Consolidated Variable Interest Entities
	The Company is the investment manager of certain asset-backed investment vehicles commonly referred to as collateralized loan obligations (“CLOs”) and certain other vehicles for which the Company earns fee income for investment management services, including certain investment structures in which the Company's asset management business invests with other co-investors in investment funds referred to as feeder funds. The Company may sell or syndicate investments through these vehicles, principally as part of the strategic investing activity of the Company's asset management businesses. Additionally, the Company may invest in securities issued by these vehicles. CLOs raise capital by issuing debt securities, and use the proceeds to purchase investments, typically interest-bearing financial instruments. The Company has analyzed these relationships and determined that for certain CLOs and other investment structures it is the primary beneficiary and consolidates these entities. This analysis includes a review of (1) the Company's rights and responsibilities as investment manager, (2) fees received by the Company and (3) other interests (if any) held by the Company. The assets of these VIEs are restricted and must be used first to settle liabilities of the VIE. The Company is not required to provide, and has not provided, material financial or other support to any of these VIEs.
	Additionally, the Company is the primary beneficiary of certain VIEs in which the Company has invested, as part of its investment activities, but for which it is not the investment manager. These include structured investments issued by a VIE that manages yen-denominated investments coupled with cross-currency coupon swap agreements thereby creating synthetic dual currency investments. The Company's involvement in the structuring of these investments combined with its economic interest indicates that the Company is the primary beneficiary. The Company has not provided material financial support or other support that was not contractually required to these VIEs.
	The table below reflects the carrying amount and balance sheet caption in which the assets and liabilities of consolidated VIEs are reported. The liabilities primarily comprise obligations under debt instruments issued by the VIEs that are non-recourse to the Company. The creditors of these VIEs do not have recourse to the Company in excess of the assets contained within the VIEs.

	Other liabilities			723		674		3		1
		Total liabilities of consolidated VIEs	$	7,553	$	6,732	$	3	$	1
	As included in the table above, notes issued by consolidated VIEs are classified in the line item on the Unaudited Interim Consolidated Statements of Financial Position titled, “Notes issued by consolidated VIEs.” Recourse is limited to the assets of the respective VIE and does not extend to the general credit of Prudential Financial. As of March 31, 2015, the maturities of these obligations were greater than five years.
	In addition, not reflected in the table above, the Company has created a trust that is a VIE, to facilitate Prudential Insurance's Funding Agreement Notes Issuance Program (“FANIP”). The trust issues medium-term notes secured by funding agreements issued to the trust by Prudential Insurance with the proceeds of such notes. The trust is the beneficiary of an indemnity agreement with the Company that provides that the Company is responsible for costs related to the notes issued, with limited exceptions. As a result, the Company has determined that it is the primary beneficiary of the trust, which is therefore consolidated.
	The funding agreements represent an intercompany transaction that is eliminated upon consolidation. However, in recognition of the security interest in such funding agreements, the trust's medium-term note liability of $2,709 million and $2,705 million at March 31, 2015 and December 31, 2014, respectively, is classified within “Policyholders' account balances.” Creditors of the trust have recourse to Prudential Insurance if the trust fails to make contractual payments on the medium-term notes. The Company has not provided material financial or other support to the trust that was not contractually required.
	Unconsolidated Variable Interest Entities
	The Company has determined that it is not the primary beneficiary of certain VIEs for which it is the investment manager. These VIEs consist primarily of investment funds for which the Company utilizes the Investment Company Model to assess consolidation. Accordingly, the Company has determined that it is not the primary beneficiary of these entities because it does not stand to absorb a majority of the VIE's expected losses or to receive a majority of the VIE's expected residual returns. For all other investment structures, the Company has determined that it is not the primary beneficiary as it does not have both (1) the power to direct the activities of the VIE that most significantly impact the economic performance of the entity and (2) the obligation to absorb losses of the entity that could be potentially significant to the VIE or the right to receive benefits from the entity that could be potentially significant. The Company's maximum exposure to loss resulting from its relationship with unconsolidated VIEs for which it is the investment manager is limited to its investment in the VIEs, which was $179 million and $137 million at March 31, 2015 and December 31, 2014, respectively. These investments are reflected in “Fixed maturities, available-for-sale,” “Other trading account assets, at fair value” and “Other long-term investments.” The fair value of assets held within these unconsolidated VIEs was $6,526 million and $6,973 million as of March 31, 2015 and December 31, 2014, respectively. There are no liabilities associated with these unconsolidated VIEs on the Company's balance sheet.
	In the normal course of its activities, the Company will invest in joint ventures and limited partnerships. These ventures include hedge funds, private equity funds and real estate-related funds and may or may not be VIEs. The Company's maximum exposure to loss on these investments, both VIEs and non-VIEs, is limited to the amount of its investment. The Company has determined that it is not required to consolidate these entities because either (1) it does not control them or (2) it does not have the obligation to absorb losses of the entities that could be potentially significant to the entities or the right to receive benefits from the entities that could be potentially significant. The Company classifies these investments as “Other long-term investments” and its maximum exposure to loss associated with these entities was $7,684 million and $7,545 million as of March 31, 2015 and December 31, 2014, respectively.
	In addition, in the normal course of its activities, the Company will invest in structured investments including VIEs for which it is not the investment manager. These structured investments typically invest in fixed income investments and are managed by third parties and include asset-backed securities, commercial mortgage-backed securities and residential mortgage-backed securities. The Company's maximum exposure to loss on these structured investments, both VIEs and non-VIEs, is limited to the amount of its investment. See Note 4 for details regarding the carrying amounts and classification of these assets. The Company has not provided material financial or other support that was not contractually required to these structures. The Company has determined that it is not the primary beneficiary of these structures due to the fact that it does not control these entities.

Closed Block Disclosure [Abstract]
Closed Block Note Disclosure [Text Block]	6.    CLOSED BLOCK
	On the date of demutualization, Prudential Insurance established a Closed Block for certain individual life insurance policies and annuities issued by Prudential Insurance in the U.S. The recorded assets and liabilities were allocated to the Closed Block at their historical carrying amounts. The Closed Block forms the principal component of the Closed Block division.
	The policies included in the Closed Block are specified individual life insurance policies and individual annuity contracts that were in force on the effective date of the Plan of Reorganization and for which Prudential Insurance is currently paying or expects to pay experience-based policy dividends. Assets have been allocated to the Closed Block in an amount that has been determined to produce cash flows which, together with revenues from policies included in the Closed Block, are expected to be sufficient to support obligations and liabilities relating to these policies, including provision for payment of benefits, certain expenses, and taxes and to provide for continuation of the policyholder dividend scales in effect in 2000, assuming experience underlying such scales continues. To the extent that, over time, cash flows from the assets allocated to the Closed Block and claims and other experience related to the Closed Block are, in the aggregate, more or less favorable than what was assumed when the Closed Block was established, total dividends paid to Closed Block policyholders may be greater than or less than the total dividends that would have been paid to these policyholders if the policyholder dividend scales in effect in 2000 had been continued. Any cash flows in excess of amounts assumed will be available for distribution over time to Closed Block policyholders and will not be available to stockholders. If the Closed Block has insufficient funds to make guaranteed policy benefit payments, such payments will be made from Prudential Insurance's assets outside of the Closed Block. The Closed Block will continue in effect as long as any policy in the Closed Block remains in force unless, with the consent of the New Jersey insurance regulator, it is terminated earlier.
	The excess of Closed Block liabilities over Closed Block assets at the date of the demutualization (adjusted to eliminate the impact of related amounts in AOCI) represented the estimated maximum future earnings at that date from the Closed Block expected to result from operations attributed to the Closed Block after income taxes. In establishing the Closed Block, the Company developed an actuarial calculation of the timing of such maximum future earnings. If actual cumulative earnings of the Closed Block from inception through the end of any given period are greater than the expected cumulative earnings, only the expected earnings will be recognized in income. Any excess of actual cumulative earnings over expected cumulative earnings will represent undistributed accumulated earnings attributable to policyholders, which are recorded as a policyholder dividend obligation. The policyholder dividend obligation represents amounts to be paid to Closed Block policyholders as an additional policyholder dividend unless otherwise offset by future Closed Block performance that is less favorable than originally expected. If the actual cumulative earnings of the Closed Block from its inception through the end of any given period are less than the expected cumulative earnings of the Closed Block, the Company will recognize only the actual earnings in income. However, the Company may reduce policyholder dividend scales, which would be intended to increase future actual earnings until the actual cumulative earnings equaled the expected cumulative earnings.
	As of March 31, 2015 and December 31, 2014, the Company recognized a policyholder dividend obligation of $1,833 million and $1,558 million, respectively, to Closed Block policyholders for the excess of actual cumulative earnings over the expected cumulative earnings. Additionally, accumulated net unrealized investment gains that have arisen subsequent to the establishment of the Closed Block have been reflected as a policyholder dividend obligation of $5,419 million and $5,053 million at March 31, 2015 and December 31, 2014, respectively, to be paid to Closed Block policyholders unless offset by future experience, with a corresponding amount reported in AOCI.
	Closed Block liabilities and assets designated to the Closed Block, as well as maximum future earnings to be recognized from Closed Block liabilities and Closed Block assets, are as follows:

	Excludes the current portion of long-term debt.
	Commercial Paper
	Prudential Financial has a commercial paper program with an authorized capacity of $3.0 billion. Prudential Financial's commercial paper borrowings have been generally used to fund the working capital needs of Prudential Financial's subsidiaries and provide short-term liquidity at Prudential Financial.
	Prudential Funding, LLC (“Prudential Funding”), a wholly-owned subsidiary of Prudential Insurance, has a commercial paper program with an authorized capacity of $7.0 billion. Prudential Funding commercial paper borrowings generally have served as an additional source of financing to meet the working capital needs of Prudential Insurance and its subsidiaries. Prudential Funding also lends to other subsidiaries of Prudential Financial up to limits agreed with the New Jersey Department of Banking and Insurance (“NJDOBI”). Prudential Funding maintains a support agreement with Prudential Insurance whereby Prudential Insurance has agreed to maintain Prudential Funding's tangible net worth at a positive level. Additionally, Prudential Financial has issued a subordinated guarantee covering Prudential Funding's $7.0 billion commercial paper program.
	Federal Home Loan Bank of New York
	Prudential Insurance is a member of the Federal Home Loan Bank of New York (“FHLBNY”). Membership allows Prudential Insurance access to the FHLBNY's financial services, including the ability to obtain collateralized loans and to issue collateralized funding agreements. Under applicable law, the funding agreements issued to the FHLBNY have priority claim status above debt holders of Prudential Insurance. FHLBNY borrowings and funding agreements are collateralized by qualifying mortgage-related assets or U.S. Treasury securities, the fair value of which must be maintained at certain specified levels relative to outstanding borrowings. FHLBNY membership requires Prudential Insurance to own member stock and borrowings require the purchase of activity-based stock in an amount equal to 4.5% of outstanding borrowings. Under FHLBNY guidelines, if Prudential Insurance's financial strength ratings decline below A/A2/A Stable by S&P/Moody's/Fitch, respectively, and the FHLBNY does not receive written assurances from the NJDOBI regarding Prudential Insurance's solvency, new borrowings from the FHLBNY would be limited to a term of 90 days or less. Currently there are no restrictions on the term of borrowings from the FHLBNY.
	NJDOBI permits Prudential Insurance to pledge collateral to the FHLBNY in an amount of up to 5% of its prior year-end statutory net admitted assets, excluding separate account assets. Based on Prudential Insurance's statutory net admitted assets as of December 31, 2014, the 5% limitation equates to a maximum amount of pledged assets of $8.9 billion and an estimated maximum borrowing capacity (after taking into account required collateralization levels) of approximately $7.5 billion. Nevertheless, FHLBNY borrowings are subject to the FHLBNY's discretion and to the availability of qualifying assets at Prudential Insurance.
	As of March 31, 2015, Prudential Insurance had pledged assets with a fair value of $2.8 billion supporting an outstanding advance of $280 million that is in “Short-term debt” and matures in December 2015 and outstanding funding agreements totaling $1.9 billion that are included in “Policyholders' account balances.” The fair value of qualifying assets that were available to Prudential Insurance but not pledged amounted to $5.5 billion as of March 31, 2015.
	Federal Home Loan Bank of Boston
	Prudential Retirement Insurance and Annuity Company (“PRIAC”) is a member of the Federal Home Loan Bank of Boston (“FHLBB”). Membership allows PRIAC access to collateralized advances which will be classified in “Short-term debt” or “Long-term debt,” depending on the maturity date of the obligation. PRIAC's membership in FHLBB requires the ownership of member stock and borrowings from FHLBB require the purchase of activity-based stock in an amount between 3.0% and 4.5% of outstanding borrowings depending on the maturity date of the obligation. As of March 31, 2015, PRIAC had no advances outstanding under the FHLBB facility.
	Under Connecticut state insurance law, without the prior consent of the Connecticut Insurance Department, the amount of assets insurers may pledge to secure debt obligations is limited to the lesser of 5% of prior-year statutory admitted assets or 25% of prior-year statutory surplus, resulting in a maximum borrowing capacity for PRIAC under the FHLBB facility of approximately $210 million as of March 31, 2015.
	Credit Facilities
	At March 31, 2015, the Company's syndicated, unsecured committed credit facilities, which were subsequently amended and restated as described below, were as follows:
				Original		Expiration
		Borrower		Term		Date		Capacity			Outstanding
								(in millions)
		Prudential Financial		5-year		Nov-18	$	2,000		$	0
		Prudential Financial and Prudential Funding		3-year		Nov-16		1,750			0
							$	3,750		$	0
	Borrowings under these credit facilities were conditioned on the Company's maintenance of consolidated net worth of at least $18.985 billion, which for this purpose was calculated as U.S. GAAP equity, excluding AOCI and equity of noncontrolling interests. As of March 31, 2015, the Company's consolidated net worth exceeded this required minimum amount.
	On April 14, 2015, the Company entered into a new $4.0 billion five-year credit facility that has both Prudential Financial and Prudential Funding as borrowers. This new credit facility amends and restates the Company's prior credit facilities shown in the table above. Borrowings under the new credit facility may be used for general corporate purposes, and the Company expects that it may borrow under the new facility from time to time to fund its working capital needs. In addition, amounts under the new credit facility may be drawn in the form of standby letters of credit that can be used to meet the Company's operating needs. Similar to the former credit facilities, the new credit facility contains representations and warranties, covenants and events of default that are customary for facilities of this type, and borrowings under the facility are not contingent on the Company's credit ratings nor subject to material adverse change clauses. Borrowings under the new credit facility are conditioned on the Company's maintenance of consolidated net worth of at least $18.985 billion, which, under this facility, is calculated as U.S. GAAP equity, excluding AOCI, equity of noncontrolling interests, and equity attributable to the Closed Block.
	Put Option Agreement for Senior Debt Issuance
	In November 2013, Prudential Financial entered into a ten-year put option agreement with a Delaware trust upon the completion of the sale of $1.5 billion of trust securities by that Delaware trust in a Rule 144A private placement. The trust invested the proceeds from the sale of the trust securities in a portfolio of principal and interest strips of U.S. Treasury securities. The put option agreement provides Prudential Financial the right to sell to the trust at any time up to $1.5 billion of 4.419% senior notes due November 2023 and receive in exchange a corresponding amount of the principal and interest strips of the U.S. Treasury securities held by the trust. In return, the Company agreed to pay a semi-annual put premium to the trust at a rate of 1.777% per annum applied to the unexercised portion of the put option. The put option agreement with the trust provides Prudential Financial with a source of liquid assets.
	The put option described above will be exercised automatically in full upon the Company's failure to make certain payments to the trust, such as paying the put option premium or reimbursing the trust for its expenses, if the Company's failure to pay is not cured within 30 days, and upon an event involving its bankruptcy. The Company is also required to exercise the put option if its consolidated stockholders' equity, calculated in accordance with GAAP but excluding AOCI, falls below $7.0 billion, subject to adjustment in certain cases. The Company has a one-time right to unwind a prior voluntary exercise of the put option by repurchasing all of the senior notes then held by the trust in exchange for principal and interest strips of U.S. Treasury securities. Finally, any of the 4.419% senior notes that Prudential Financial issues may be redeemed prior to their maturity at par or, if greater, a make-whole price, following a voluntary exercise in full of the put option.
	Long-term Debt
	Surplus Notes
	During the first quarter of 2015, the Company increased by $262 million the principal amount of surplus notes outstanding under its captive financing facility initially established in December 2013 for the financing of non-economic reserves required under Guideline AXXX. As of March 31, 2015, an aggregate of $2,100 million of surplus notes were outstanding under this facility and no credit-linked note payments have been required.
	On February 18, 2015, Prudential Legacy Insurance Company of NJ (“PLIC”) entered into a twenty-year financing facility with certain unaffiliated financial institutions and with Essex, LLC (“LLC”), a special-purpose company affiliate, pursuant to which PLIC may, at its option and subject to the satisfaction of customary conditions, issue and sell to LLC up to $4.0 billion in aggregate principal amount of surplus notes in return for an equal principal amount of credit-linked notes issued by LLC. Upon issuance, PLIC would hold any credit-linked notes as assets to finance future statutory surplus needs within PLIC. As of March 31, 2015, there were no surplus notes outstanding under the facility.
	Senior Notes
	Medium-term notes. Prudential Financial maintains a medium-term note program under its shelf registration statement with an authorized issuance capacity of $20.0 billion. As of March 31, 2015, the outstanding balance of the Company's medium-term notes was $12.0 billion, a decrease of $1.0 billion from December 31, 2014, due to maturities.
	Retail medium-term notes. Prudential Financial also maintains a retail medium-term notes program, including the InterNotes program, under its shelf registration statement with an authorized issuance capacity of $5.0 billion. As of March 31, 2015, the outstanding balance of retail notes was $448 million. Retail notes outstanding increased $73 million from December 31, 2014 primarily due to the issuance of $107 million of notes offset by maturities of $34 million of notes in 2015.
	Mortgage debt. As of March 31, 2015, the Company's insurance subsidiaries had mortgage debt of $519 million that has recourse only to real estate property held for investment by those subsidiaries. This represents an increase of $17 million from December 31, 2014, due to new borrowings in 2015 of $92 million offset by prepayments and foreign exchange fluctuations totaling $75 million.

	In June 2014, Prudential Financial's Board of Directors authorized the Company to repurchase at management's discretion up to $1.0 billion of its outstanding Common Stock from July 1, 2014 through June 30, 2015. As of March 31, 2015, 8.8 million shares of the Company's Common Stock were repurchased under this authorization at a total cost of $750 million, of which 3.1 million shares were repurchased in the first three months of 2015 at a total cost of $250 million.
	The timing and amount of share repurchases are determined by management based upon market conditions and other considerations, and repurchases may be effected in the open market, through derivative, accelerated repurchase and other negotiated transactions and through prearranged trading plans complying with Rule 10b5-1(c) under the Securities Exchange Act of 1934 (the “Exchange Act”). Numerous factors could affect the timing and amount of any future repurchases under the share repurchase authorization, including increased capital needs of the Company due to changes in regulatory capital requirements, opportunities for growth and acquisitions, and the effect of adverse market conditions on the segments.
	Class B Stock
	On December 1, 2014, Prudential Financial entered into a Share Repurchase Agreement with the holders of the Class B Stock to repurchase all of the 2.0 million outstanding shares of Class B Stock for an aggregate cash purchase price of $650.8 million. As a result, all of the outstanding shares of Class B Stock were reclassified as “held in treasury” as of December 31, 2014, resulting in a reduction to “Total Prudential Financial, Inc. equity.” As discussed in Note 1, on January 2, 2015, the Company repurchased and cancelled all of the shares of the Class B Stock, resulting in the elimination of the Class B Stock held in treasury, a $483.8 million decrease in “Retained earnings” and a $167.0 million decrease in “Additional paid-in capital.”
	In accordance with the terms of the Share Repurchase Agreement, the holders of a majority of the Class B Stock have exercised their right to dispute the calculation of the purchase price. Accordingly, the final purchase price of the Class B Stock could change.

Earnings Per Share
Earnings Per Share	8.    EARNINGS PER SHARE
	From demutualization through December 31, 2014, the Company had two separate classes of common stock. The Common Stock reflected the performance of the Company's former Financial Services Businesses and the Class B Stock reflected the performance of the Company's former Closed Block Business. Earnings per share were calculated separately for each of these two classes of common stock and included a direct equity adjustment to modify the earnings available to each of the classes of common stock for the difference between the allocation of general and administrative expenses to each of the businesses and the cash flows between the businesses related to these expenses. Accordingly, earnings per share of Common Stock presented below for the three months ended March 31, 2014, reflect earnings attributable to the former Financial Services Businesses.
	As discussed in Note 1, on January 2, 2015, Prudential Financial repurchased and cancelled all of the 2.0 million shares of the Class B Stock. Accordingly, earnings per share of Common Stock presented below for the three months ended March 31, 2015, reflect the consolidated earnings of Prudential Financial. In addition, the Class B Repurchase resulted in the elimination of the separation of the former Financial Services Businesses and Closed Block Business. As a result, there was no direct equity adjustment recorded for the three months ended March 31, 2015.
	Earnings per share of the Class B Stock for the three months ended March 31, 2014, is not presented herein as it is not meaningful due to the Class B Repurchase.
	A reconciliation of the numerators and denominators of the basic and diluted per share computations of Common Stock based on the consolidated earnings of Prudential Financial for the three months ended March 31, 2015, is as follows:

	Income from continuing operations per share of Class B Stock for the three months ended March 31, 2104 is presented below. There were no potentially dilutive shares associated with the Class B Stock.
	Unvested share-based payment awards that contain nonforfeitable rights to dividends are participating securities and included in the computation of earnings per share pursuant to the two-class method. Under this method, earnings attributable to Prudential Financial are allocated between Common Stock and the participating awards, as if the awards were a second class of stock. During periods of income from continuing operations available to holders of Common Stock, after direct equity adjustment as applicable, the calculation of earnings per share excludes the income attributable to participating securities in the numerator and the dilutive impact of these securities from the denominator. In the event of loss from continuing operations available to holders of Common Stock, after direct equity adjustment as applicable, undistributed earnings are not allocated to participating securities and the denominator excludes the dilutive impact of these securities as they do not share in the losses of the Company. Undistributed earnings allocated to participating unvested share-based payment awards for the three months ended March 31, 2015 and 2014, as applicable, were based on 4.5 million and 4.3 million of such awards, respectively, weighted for the period they were outstanding.
	Stock options and shares related to deferred and long-term compensation programs that are considered antidilutive are excluded from the computation of dilutive earnings per share. Stock options are considered antidilutive based on application of the treasury stock method or in the event of loss from continuing operations available to holders of Common Stock, after direct equity adjustment as applicable. Shares related to deferred and long-term compensation programs are considered antidilutive in the event of loss from continuing operations available to holders of Common Stock, after direct equity adjustment as applicable. For the three months ended March 31, 2015 and 2014, the number of stock options and shares related to deferred and long-term compensation programs that were considered antidilutive and were excluded from the computation of diluted earnings per share, weighted for the portion of the period they were outstanding, are as follows:
				Three Months Ended March 31,

	In September 2009, the Company issued $500 million of surplus notes with an interest rate of 5.36% per annum which are exchangeable at the option of the note holders for shares of Common Stock. The initial exchange rate for the surplus notes was 10.1235 shares of Common Stock per each $1,000 principal amount of surplus notes, which represents an initial exchange price per share of Common Stock of $98.78; however, the exchange rate is subject to customary anti-dilution adjustments. In calculating diluted earnings per share under the if-converted method, the potential shares that would be issued assuming a hypothetical exchange, weighted for the period the notes are outstanding, are added to the denominator, and interest expense, net of tax, is added to the numerator, if the overall effect is dilutive.

	The Company has funded and non-funded non-contributory defined benefit pension plans, which cover substantially all of its employees. For some employees, benefits are based on final average earnings and length of service, while benefits for other employees are based on an account balance that takes into consideration age, service and earnings during their career.
	The Company provides certain health care and life insurance benefits for its retired employees, their beneficiaries and covered dependents (“other postretirement benefits”). The health care plan is contributory; the life insurance plan is non-contributory. Substantially all of the Company's U.S. employees may become eligible to receive other postretirement benefits if they retire after age 55 with at least 10 years of service or under certain circumstances after age 50 with at least 20 years of continuous service.

Income Taxes	12.    INCOME TAXES
	The Company's liability for income taxes includes the liability for unrecognized tax benefits, interest and penalties which relate to tax years still subject to review by the Internal Revenue Service (“IRS”) or other taxing authorities. Audit periods remain open for review until the statute of limitations has passed. Generally, for tax years which produce net operating losses, capital losses or tax credit carryforwards (“tax attributes”), the statute of limitations does not close, to the extent of these tax attributes, until the expiration of the statute of limitations for the tax year in which they are fully utilized. The completion of review or the expiration of the statute of limitations for a given audit period could result in an adjustment to the liability for income taxes.
	The Company does not anticipate any significant changes within the next 12 months to its total unrecognized tax benefits related to tax years for which the statute of limitations has not expired.
	Listed below are the tax years that remain subject to examination by major tax jurisdiction, at March 31, 2015:
	Major Tax Jurisdiction		Open Tax Years
	United States		2007 - 2014
	Japan		Fiscal years ended March 31, 2010 - 2015
	Korea		Fiscal years ended March 31, 2010 - 2013, nine months ended December 31, 2013 and calendar year 2014
	The dividends received deduction (“DRD”) reduces the amount of dividend income subject to U.S. tax and is a significant component of the difference between the Company's effective tax rate and the federal statutory tax rate of 35%. The DRD for the current period was estimated using information from 2014 and current year results, and was adjusted to take into account the current year's equity market performance and expected business results. The actual current year DRD can vary from the estimate based on factors such as, but not limited to, changes in the amount of dividends received that are eligible for the DRD, changes in the amount of distributions received from mutual fund investments, changes in the account balances of variable life and annuity contracts, and the Company's taxable income before the DRD.
	There is a possibility that the IRS and the U.S. Treasury will address, through guidance, issues related to the calculation of the DRD. For the last several years, revenue proposals included in the Obama Administration's budgets have included proposed changes to the method used to determine the amount of the DRD. A change in the DRD, including the possible retroactive or prospective elimination of this deduction through guidance or legislation, could increase actual tax expense and reduce the Company's consolidated net income.
	For tax years 2007 through 2015, the Company is participating in the IRS's Compliance Assurance Program (“CAP”). Under CAP, the IRS assigns an examination team to review completed transactions as they occur in order to reach agreement with the Company on how they should be reported in the relevant tax returns. If disagreements arise, accelerated resolutions programs are available to resolve the disagreements in a timely manner before the tax returns are filed.
	Total income tax expense includes additional tax expense related to the realization of deferred tax assets recorded in the Unaudited Interim Consolidated Statements of Financial Position as of the acquisition date for Prudential Gibraltar Financial Life Insurance Company, Ltd. (“Prudential Gibraltar”) Prudential Gibraltar and AIG Star Life Insurance Co., Ltd, AIG Edison Life Insurance Company, AIG Financial Assurance Japan K.K., and AIG Edison Service Co., Ltd. (collectively, the “Star and Edison Businesses”).

Fair Value of Assets and Liabilities [Abstract]
Fair Value of Assets and Liabilities	13.    FAIR VALUE OF ASSETS AND LIABILITIES
	Fair Value Measurement—Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The authoritative fair value guidance establishes a framework for measuring fair value that includes a hierarchy used to classify the inputs used in measuring fair value. The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. The levels of the fair value hierarchy are as follows:
	Level 1—Fair value is based on unadjusted quoted prices in active markets that are accessible to the Company for identical assets or liabilities. The Company's Level 1 assets and liabilities primarily include certain cash equivalents and short term investments, equity securities and derivative contracts that trade on an active exchange market.
	Level 2—Fair value is based on significant inputs, other than quoted prices included in Level 1, that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets and liabilities, quoted market prices in markets that are not active for identical or similar assets or liabilities, and other market observable inputs. The Company's Level 2 assets and liabilities include: fixed maturities (corporate public and private bonds, most government securities, certain asset-backed and mortgage-backed securities, etc.), certain equity securities (mutual funds, which do not actively trade and are priced based on a net asset value (“NAV”)), certain commercial mortgage loans, short-term investments and certain cash equivalents (primarily commercial paper), and certain over-the-counter (“OTC”) derivatives.
	Level 3—Fair value is based on at least one or more significant unobservable inputs for the asset or liability. The assets and liabilities in this category may require significant judgment or estimation in determining the fair value. The Company's Level 3 assets and liabilities primarily include: certain private fixed maturities and equity securities, certain manually priced public equity securities and fixed maturities, certain highly structured over-the-counter derivative contracts, certain commercial mortgage loans, certain consolidated real estate funds for which the Company is the general partner, and embedded derivatives resulting from certain products with guaranteed benefits.
	Assets and Liabilities by Hierarchy Level—The tables below present the balances of assets and liabilities reported at fair value on a recurring basis, as of the dates indicated.

“Netting” amounts represent cash collateral of $9,208 million and $5,671 million as of March 31, 2015 and December 31, 2014, respectively, and the impact of offsetting asset and liability positions held with the same counterparty, subject to master netting arrangements.
Includes “Trading account assets supporting insurance liabilities” and “Other trading account assets.”
Level 1 represents cash equivalents and short term investments. All other amounts primarily represent derivative assets.
Separate account assets represent segregated funds that are invested for certain customers. Investment risks associated with market value changes are borne by the customers, except to the extent of minimum guarantees made by the Company with respect to certain accounts. Separate account assets classified as Level 3 consist primarily of real estate and real estate investment funds. Separate account liabilities are not included in the above table as they are reported at contract value and not fair value in the Company's Unaudited Interim Consolidated Statements of Financial Position.
As of March 31, 2015, the net embedded derivative liability position of $9.4 billion includes $0.6 billion of embedded derivatives in an asset position and $10.0 billion of embedded derivatives in a liability position. For the year ended December 31, 2014, the net embedded derivative liability position of $8.2 billion includes $0.6 billion of embedded derivatives in an asset position and $8.8 billion of embedded derivatives in a liability position.
The methods and assumptions the Company uses to estimate the fair value of assets and liabilities measured at fair value on a recurring basis are summarized below.
Fixed Maturity Securities—The fair values of the Company's public fixed maturity securities are generally based on prices obtained from independent pricing services. Prices for each security are generally sourced from multiple pricing vendors, and a vendor hierarchy is maintained by asset type based on historical pricing experience and vendor expertise. The Company ultimately uses the price from the pricing service highest in the vendor hierarchy based on the respective asset type. The pricing hierarchy is updated for new financial products and recent pricing experience with various vendors. Consistent with the fair value hierarchy described above, securities with validated quotes from pricing services are generally reflected within Level 2, as they are primarily based on observable pricing for similar assets and/or other market observable inputs. Typical inputs used by these pricing services include but are not limited to, reported trades, benchmark yields, issuer spreads, bids, offers, and/or estimated cash flow, prepayment speeds, and default rates. If the pricing information received from third party pricing services is deemed not reflective of market activity or other inputs observable in the market, the Company may challenge the price through a formal process with the pricing service or classify the securities as Level 3. If the pricing service updates the price to be more consistent with the presented market observations, the security remains within Level 2.
Internally-developed valuations or indicative broker quotes are also used to determine fair value in circumstances where vendor pricing is not available, or where the Company ultimately concludes that pricing information received from independent pricing services is not reflective of market activity. If the Company concludes the values from both pricing services and brokers are not reflective of market activity, it may override the information with an internally-developed valuation. As of March 31, 2015 and December 31, 2014, overrides on a net basis were not material. Pricing service overrides, internally-developed valuations and indicative broker quotes are generally included in Level 3 in the fair value hierarchy.
The Company conducts several specific price monitoring activities. Daily analyses identify price changes over predetermined thresholds defined at the financial instrument level. Various pricing integrity reports are reviewed on a daily and monthly basis to determine if pricing is reflective of market activity or if it would warrant any adjustments. Other procedures performed include, but are not limited to, reviews of third-party pricing services methodologies, reviews of pricing trends, and back testing.
The fair value of private fixed maturities, which are comprised of investments in private placement securities, originated by internal private asset managers, are primarily determined using discounted cash flow models. These models primarily use observable inputs that include Treasury or similar base rates plus estimated credit spreads to value each security. The credit spreads are obtained through a survey of private market intermediaries who are active in both primary and secondary transactions, and consider, among other factors, the credit quality and industry sector of the issuer and the reduced liquidity associated with private placements. Since most private placements are valued using standard market observable inputs and inputs derived from, or corroborated by, market observable data including observed prices and spreads for similar publicly traded or privately traded issues, they have been reflected within Level 2. For certain private fixed maturities, the discounted cash flow model may incorporate significant unobservable inputs, which reflect the Company's own assumptions about the inputs that market participants would use in pricing the asset. To the extent management determines that such unobservable inputs are significant to the price of a security, a Level 3 classification is made.
Trading Account Assets—Trading account assets consist primarily of fixed maturity securities, equity securities and derivatives whose fair values are determined consistent with similar instruments described above under “Fixed Maturity Securities” and below under “Equity Securities” and “Derivative Instruments.”
Equity Securities—Equity securities consist principally of investments in common and preferred stock of publicly traded companies, perpetual preferred stock, privately traded securities, as well as mutual fund shares. The fair values of most publicly traded equity securities are based on quoted market prices in active markets for identical assets and are classified within Level 1 in the fair value hierarchy. Estimated fair values for most privately traded equity securities are determined using discounted cash flow, earnings multiple and other valuation models that require a substantial level of judgment around inputs and therefore are classified within Level 3. The fair values of mutual fund shares that transact regularly (but do not trade in active markets because they are not publicly available) are based on transaction prices of identical fund shares and are classified within Level 2 in the fair value hierarchy. The fair values of perpetual preferred stock are based on inputs obtained from independent pricing services that are primarily based on indicative broker quotes. As a result, the fair values of perpetual preferred stock are classified as Level 3.
Commercial Mortgage and Other Loans—The fair value of commercial mortgage loans held for investment and accounted for using the fair value option are determined based on the present value of the expected future cash flows discounted at the appropriate U.S. Treasury rate, adjusted for the current market spread for similar quality loans. The quality ratings for these loans, a primary determinant of the appropriate credit spread and a significant component of the pricing input, are based on internally-developed estimates. As a result, these loans are included in Level 3 in the fair value hierarchy.
The fair value of other loans held and accounted for using the fair value option is determined utilizing pricing indicators from the whole loan market, where investors are committed to purchase these loans at a predetermined price, which is considered the principal exit market for these loans. The Company has evaluated the valuation inputs used for these assets, including the existence of predetermined exit prices, the terms of the loans, prevailing interest rates and credit risk, and deemed that the primary pricing inputs are Level 2 inputs in the fair value hierarchy.
Other Long-Term Investments—Other long-term investments include limited partnerships which are consolidated because the Company is either deemed to exercise control or considered the primary beneficiary of a variable interest entity. These entities are considered investment companies and follow specialized industry accounting whereby their assets are carried at fair value. The investments held by these entities include various feeder fund investments in underlying master funds (whose underlying holdings generally include public fixed maturities, equity securities and mutual funds), as well as wholly-owned real estate held within other investment funds. The fair value is determined by reference to the underlying direct investments, with publicly traded equity securities based on quoted prices in active markets reflected in Level 1, and public fixed maturities and mutual funds priced via quotes from pricing services or observable data reflected in Level 2. The fair value of investments in funds that are subject to significant liquidity restrictions are reflected in Level 3.
The fair value of real estate held in consolidated investment funds is determined through an independent appraisal process. The appraisals generally utilize a discounted cash flow model, supplemented with replacement cost estimates and comparable recent sales data when available. These appraisals and the related assumptions are updated at least annually. Since many of the assumptions utilized are unobservable and are considered to be significant inputs to the valuation, the real estate investments within other long-term investments have been reflected within Level 3 in the fair value hierarchy.
The fair value of fund investments, where the fair value option has been elected, is primarily determined by the fund managers and is measured at fair value using NAV as a practical expedient. Since the valuations may be based on unobservable market inputs and cannot be validated by the Company, these investments have been included within Level 3 in the fair value hierarchy.
Derivative Instruments—Derivatives are recorded at fair value either as assets, within “Other trading account assets,” or “Other long-term investments,” or as liabilities, within “Other liabilities,” except for embedded derivatives which are recorded with the associated host contract. The fair values of derivative contracts can be affected by changes in interest rates, foreign exchange rates, commodity prices, credit spreads, market volatility, expected returns, NPR, liquidity and other factors. For derivative positions included within Level 3 of the fair value hierarchy, liquidity valuation adjustments are made to reflect the cost of exiting significant risk positions, and consider the bid-ask spread, maturity, complexity, and other specific attributes of the underlying derivative position.
The Company's exchange-traded futures and options include Treasury futures, Eurodollar futures, commodity futures, Eurodollar options and commodity options. Exchange-traded futures and options are valued using quoted prices in active markets and are classified within Level 1 in the fair value hierarchy.
The majority of the Company's derivative positions are traded in the OTC derivative market and are classified within Level 2 in the fair value hierarchy. OTC derivatives classified within Level 2 are valued using models that utilize actively quoted or observable market input values from external market data providers, third-party pricing vendors and/or recent trading activity. The Company's policy is to use mid-market pricing in determining its best estimate of fair value. The fair values of most OTC derivatives, including interest rate and cross currency swaps, currency forward contracts, commodity swaps, commodity forward contracts, single name credit default swaps, loan commitments held for sale and “to be announced” (“TBA”) forward contracts on highly rated mortgage-backed securities issued by U.S. government sponsored entities are determined using discounted cash flow models. The fair values of European style option contracts are determined using Black-Scholes option pricing models. These models' key inputs include the contractual terms of the respective contract, along with significant observable inputs, including interest rates, currency rates, credit spreads, equity prices, index dividend yields, NPR, volatility and other factors.
The Company's cleared interest rate swaps and credit derivatives linked to an index are valued using models that utilize actively quoted or observable market inputs, including Overnight Indexed Swap discount rates, obtained from external market data providers, third-party pricing vendors and/or recent trading activity. These derivatives are classified as Level 2 in the fair value hierarchy.
The vast majority of the Company's derivative agreements are with highly rated major international financial institutions. To reflect the market's perception of its own and the counterparty's NPR, the Company incorporates additional spreads over London Interbank Offered Rates (“LIBOR”) into the discount rate used in determining the fair value of OTC derivative assets and liabilities that are not otherwise collateralized.
Derivatives classified as Level 3 include look-back equity options and other structured products. These derivatives are valued based upon models, such as Monte Carlo simulation models and other techniques that utilize significant unobservable inputs. Level 3 methodologies are validated through periodic comparison of the Company's fair values to external broker-dealer values.
Cash Equivalents and Short-Term Investments—Cash equivalents and short-term investments include money market instruments, commercial paper and other highly liquid debt instruments. Certain money market instruments are valued using unadjusted quoted prices in active markets that are accessible for identical assets and are primarily classified as Level 1. The remaining instruments in this category are generally fair valued based on market observable inputs and these investments have primarily been classified within Level 2.
Separate Account Assets—Separate account assets include fixed maturity securities, treasuries, equity securities, mutual funds, and real estate investments for which values are determined consistent with similar instruments described above under “Fixed Maturity Securities,” “Equity Securities” and “Other Long-Term Investments.”
Notes issued by Consolidated VIEs—The fair values of these notes are based on indicative broker quotes and classified within Level 3. See Note 5 and the Fair Value Option section below for additional information.
Other Liabilities—Other liabilities include certain derivative instruments, the fair values of which are determined consistent with similar derivative instruments described above under “Derivative Instruments.”
Future Policy Benefits—The liability for future policy benefits is related to guarantees primarily associated with the optional living benefit features of certain variable annuity contracts offered by the Company's Individual Annuities segment, including guaranteed minimum accumulation benefits (“GMAB”)GMAB, guaranteed minimum withdrawal benefits (“GMWB”)GMWB and guaranteed minimum income and withdrawal benefits (“GMIWB”)GMIWB, accounted for as embedded derivatives. The fair values of these liabilities are calculated as the present value of future expected benefit payments to customers less the present value of assessed rider fees attributable to the embedded derivative feature. This methodology could result in either a liability or contra-liability balance, given changing capital market conditions and various actuarial assumptions. Since there is no observable active market for the transfer of these obligations, the valuations are calculated using internally-developed models with option pricing techniques. The models are based on a risk neutral valuation framework and incorporate premiums for risks inherent in valuation techniques, inputs, and the general uncertainty around the timing and amount of future cash flows. The determination of these risk premiums requires the use of management judgment.
The significant inputs to the valuation models for these embedded derivatives include capital market assumptions, such as interest rate levels and volatility assumptions, the Company's market-perceived NPR, as well as actuarially determined assumptions, including contractholder behavior, such as lapse rates, benefit utilization rates, withdrawal rates, and mortality rates. Since many of these 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 in the fair value hierarchy.
Capital market inputs and actual policyholders' account values are updated each quarter based on capital market conditions as of the end of the quarter, including interest rates, equity markets and volatility. In the risk neutral valuation, the initial swap curve drives the total return used to grow the policyholders' account values. The Company's discount rate assumption is based on the LIBOR swap curve adjusted for an additional spread relative to LIBOR to reflect NPR.
Actuarial assumptions, including contractholder behavior and mortality, are reviewed at least annually, and updated based upon emerging experience, future expectations and other data, including any observable market data. These assumptions are generally updated annually unless a material change that the Company feels is indicative of a long term trend is observed in an interim period.
Transfers between Levels 1 and 2—Overall, transfers between levels are made to reflect changes in observability of inputs and market activity. Transfers into or out of any level are assumed to occur at the beginning of the quarter in which the transfers occur. Periodically there are transfers between Level 1 and Level 2 for assets held in the Company's Separate Account. The fair value of foreign common stock held in the Company's Separate Account may reflect differences in market levels between the close of foreign trading markets and the close of U.S. trading markets for the respective day. Dependent on the existence of such a timing difference, the assets may move between Level 1 and Level 2. During the three months ended March 31, 2015, $50.0 million were transferred from Level 1 to Level 2 and $17.0 million were transferred from Level 2 to Level 1. During the three months ended March 31, 2014, $0.1 billion were transferred from Level 1 to Level 2.

Conversely, the impact of a decrease in input would have the opposite impact for the fair value as that presented in the table.
Represents multiples of earnings before interest, taxes, depreciation and amortization (“EBITDA”), and are amounts used when the reporting entity has determined that market participants would use such multiples when pricing the investments.
Future policy benefits primarily represent general account liabilities for the optional living benefit features of the Company's variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.
Lapse rates are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates are also generally assumed to be lower for the period where surrender charges apply.
To reflect NPR, the Company incorporates an additional spread over LIBOR into the discount rate used in the valuation of individual living benefit contracts in a liability position and generally not to those in a contra-liability position. The NPR spread reflects the financial strength ratings of the Company as these are insurance liabilities and senior to debt. The additional spread over LIBOR is determined by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium.
The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration, and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status, and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal.
The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions may vary based on the product type, contractholder age, tax status, and withdrawal timing. The fair value of the liability will generally increase the closer the withdrawal rate is to 100%.
Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 35 to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table.
Interrelationships Between Unobservable Inputs—In addition to the sensitivities of fair value measurements to changes in each unobservable input in isolation, as reflected in the table above, interrelationships between these inputs may also exist, such that a change in one unobservable input may give rise to a change in another or multiple inputs. Examples of such interrelationships for significant internally-priced Level 3 assets and liabilities are as follows:
Corporate Securities—The rate used to discount future cash flows reflects current risk-free rates plus credit and liquidity spread requirements that market participants would use to value an asset. The discount rate may be influenced by many factors, including market cycles, expectations of default, collateral, term, and asset complexity. Each of these factors can influence discount rates, either in isolation, or in response to other factors.
Future Policy Benefits—The Company expects efficient benefit utilization and withdrawal rates to generally be correlated with lapse rates. However, behavior is generally highly dependent on the facts and circumstances surrounding the individual contractholder, such as their liquidity needs or tax situation, which could drive lapse behavior independent of other contractholder behavior assumptions. To the extent more efficient contractholder behavior results in greater in-the-moneyness at the contract level, lapse rates may decline for those contracts. Similarly, to the extent that increases in equity volatility are correlated with overall declines in the capital markets, lapse rates may decline as contracts become more in-the-money.
Separate Account Assets—In addition to the significant internally-priced Level 3 assets and liabilities presented and described above, the Company also has internally-priced separate account assets reported within Level 3. Changes in the fair value of separate account assets are borne by customers and thus are offset by changes in separate account liabilities on the Company's Unaudited Interim Consolidated Statements of Financial Position. As a result, changes in value associated with these investments do not impact the Company's Unaudited Interim Consolidated Statements of Operations. In addition, fees earned by the Company related to the management of most separate account assets classified as Level 3 do not change due to changes in the fair value of these investments. Quantitative information about significant internally-priced Level 3 separate account assets is as follows:
Real Estate and Other Invested Assets—Separate account assets include $22,743 million and $22,641 million of investments in real estate as of March 31, 2015 and December 31, 2014, respectively, that are classified as Level 3 and reported at fair value. In general, these fair value estimates are based on property appraisal reports prepared by independent real estate appraisers. Key inputs and assumptions to the appraisal process include rental income and expense amounts, related growth rates, discount rates and capitalization rates. In cases where real estate investments are made through indirect investments, fair value is generally determined by the Company's equity in net assets of the entities. The debt associated with real estate, other invested assets and the Company's equity position in entities are externally valued. Because of the subjective nature of inputs and the judgment involved in the appraisal process, real estate investments and their corresponding debt are typically included in the Level 3 classification. Key unobservable inputs to real estate valuation include capitalization rates, which ranged from 4.50% to 10.00% (6.00% weighted average) as of March 31, 2015, and 4.50% to 9.75% (6.05% weighted average) as of December 31, 2014, and discount rates, which ranged from 6.00% to 15.00% (7.29% weighted average) as of March 31, 2015, and 6.00% to 15.00% (7.36% weighted average) as of December 31, 2014. Key unobservable inputs to real estate debt valuation include yield to maturity, which ranged from 0.76% to 6.04% (3.93% weighted average) as of March 31, 2015, and 0.77% to 6.76% (4.02% weighted average) as of December 31, 2014, and market spread over base rate, which ranged from 1.50% to 4.20% (2.34% weighted average) as of March 31, 2015, and 1.50% to 4.76% (2.67% weighted average) as of December 31, 2014.
Commercial Mortgage Loans—Separate account assets include $946 million and $943 million of commercial mortgage loans as of March 31, 2015 and December 31, 2014, respectively, that are classified as Level 3 and reported at fair value. Commercial mortgage loans are primarily valued internally using discounted cash flow techniques, as described further under “Fair Value of Financial Instruments.” The primary unobservable input used is the spread to discount cash flows, which ranged from 1.20% to 8.30% (1.45% weighted average) as of March 31, 2015, and 1.17% to 8.39% (1.44% weighted average) as of December 31, 2014. In isolation, an increase (decrease) in the value of this input would result in a lower (higher) fair value measurement.
Valuation Process for Fair Value Measurements Categorized within Level 3—The Company has established an internal control infrastructure over the valuation of financial instruments that requires ongoing oversight by its various business groups. These management control functions are segregated from the trading and investing functions. For invested assets, the Company has established oversight teams, often in the form of pricing committees within each asset management group. The teams, which typically include representation from investment, accounting, operations, legal and other disciplines are responsible for overseeing and monitoring the pricing of the Company's investments and performing periodic due diligence reviews of independent pricing services. An actuarial valuation team oversees the valuation of optional living benefit features of the Company's variable annuity contracts.
The Company has also established policies and guidelines that require the establishment of valuation methodologies and consistent application of such methodologies. These policies and guidelines govern the use of inputs and price source hierarchies and provide controls around the valuation processes. These controls include appropriate review and analysis of investment prices against market activity or indicators of reasonableness, analysis of portfolio returns to corresponding benchmark returns, back-testing, review of bid/ask spreads to assess activity, approval of price source changes, price overrides, methodology changes and classification of fair value hierarchy levels. For optional living benefit features of the Company's variable annuity products, the actuarial valuation unit periodically tests contract input data and actuarial assumptions are reviewed at least annually, and updated based upon emerging experience, future expectations and other data, including any observable market data. The valuation policies and guidelines are reviewed and updated as appropriate.
Within the trading and investing functions, the Company has established policies and procedures that relate to the approval of all new transaction types, transaction pricing sources and fair value hierarchy coding within the financial reporting system. For variable annuity product changes or new launches of optional living benefit features, the actuarial valuation unit validates input logic and new product features and agrees new input data directly to source documents.

Other primarily represents reclassifications of certain assets between reporting categories and eliminations of intercompany separate account investments.
Transfers into or out of Level 3 are generally reported as the value as of the beginning of the quarter in which the transfer occurs.
Unrealized gains or losses related to assets still held at the end of the period do not include amortization or accretion of premiums and discounts.
Separate account assets represent segregated funds that are invested for certain customers. Investment risks associated with market value changes are borne by the customers, except to the extent of minimum guarantees made by the Company with respect to certain accounts. Separate account liabilities are not included in the above table as they are reported at contract value and not fair value in the Company's Unaudited Interim Consolidated Statements of Financial Position.
Prior period amounts have been reclassified to conform to current period presentation.
Transfers—Transfers into Level 3 are generally the result of unobservable inputs utilized within valuation methodologies and the use of indicative broker quotes for assets that were previously valued using observable inputs. Transfers out of Level 3 are generally due to the use of observable inputs in valuation methodologies as well as the availability of pricing service information for certain assets that the Company is able to validate.

Nonrecurring Fair Value Measurements―Certain assets and liabilities are measured at fair value on a nonrecurring basis. There were no fair value reserve adjustments for the three months ended March 31, 2015 and 2014, on certain commercial mortgage loans. The carrying value of these loans as of March 31, 2015, was $18 million. The reserve adjustments were based on discounted cash flows utilizing market rates or the fair value of the underlying real estate collateral and the underlying assets were classified as Level 3 in the valuation hierarchy.
For mortgage servicing rights, there were impairments of $3 million for the three months ended March 31, 2015, and there were no impairments for the three months ended March 31, 2014. There were valuation reserve increases of $3 million, and decreases of $4 million for the three months ended March 31, 2015 and 2014, respectively. Mortgage servicing rights are revalued based on internal models, utilizing inputs and classified as Level 3 in the valuation hierarchy. The fair value for mortgage servicing rights is determined using a discounted cash flow model incorporating assumptions for servicing revenues, adjusted for expected prepayments, delinquency rates, escrow deposit income and estimated loan servicing expenses.
There were no impairments for both the three months ended March 31, 2015 and 2014, on real estate held for investment. Key inputs and assumptions to the appraisal process include rental income and expense amounts, related growth rates, discount rates and capitalization rates. Given the subjective nature of inputs and the judgment involved in the appraisal process, real estate investments are typically included in the Level 3 classification. For certain cost method investments, there were $24 million of impairments recorded for the three months ended March 31, 2015, and no impairments recorded for the three months ended March 31, 2014. The methodologies utilized were primarily discounted future cash flow and, where appropriate, valuations provided by the general partners taking into consideration investment-related expenses. These cost method investments are classified as Level 3 in the valuation hierarchy.
Fair Value Option
The fair value option provides the Company an option to elect fair value as an alternative measurement for selected financial assets and financial liabilities not otherwise reported at fair value. Such elections have been made by the Company to help mitigate volatility in earnings that results from different measurement attributes. Electing the fair value option also allows the Company to achieve consistent accounting for certain assets and liabilities.
The following table presents information regarding changes in fair values recorded in earnings for commercial mortgage and other loans, other long-term investments and notes issued by consolidated VIEs, where the fair value option has been elected.
				Three Months Ended March 31,
				2015			2014
				(in millions)
Assets:
	Commercial mortgage and other loans:
		Changes in instrument-specific credit risk		$	0		$	0
		Other changes in fair value			0			0
	Other long-term investments:
		Changes in fair value			32			18
Liabilities:
	Notes issued by consolidated variable interest entities:
		Changes in fair value		$	-168		$	4
Changes in fair value are reflected in “Realized investment gains (losses), net” for commercial mortgage and other loans and “Other income” for other long-term investments and notes issued by consolidated VIEs. Changes in fair value due to instrument-specific credit risk are estimated based on changes in credit spreads and quality ratings for the period reported.
Interest income on commercial mortgage and other loans is included in net investment income. For the three months ended March 31, 2015 and 2014, the Company recorded $3 million and $2 million of interest income, respectively, on these fair value option loans. Interest income on these loans is recorded based on the effective interest rates as determined at the closing of the loan.
The fair values and aggregate contractual principal amounts of commercial mortgage and other loans, for which the fair value option has been elected, were $316 million and $312 million, respectively, as of March 31, 2015, and $380 million and $372 million, respectively, as of December 31, 2014. As of March 31, 2015, there were no loans in non-accrual status and none of the loans are more than 90 days past due and still accruing.
The fair value of other long-term investments was $1,203 million and $1,082 million as of March 31, 2015 and December 31, 2014, respectively.
The fair value and aggregate contractual principal amounts of limited recourse notes issued by consolidated VIEs, for which the fair value option has been elected at issuance, were $6,810 million and $7,154 million, respectively, as of March 31, 2015, and $6,033 million and $6,216 million, respectively, as of December 31, 2014. Interest expense recorded for these liabilities was $68 million and $40 million for the three months ended March 31, 2015 and 2014, respectively.

Carrying values presented herein differ from those in the Company's Unaudited Interim Consolidated Statements of Financial Position because certain items within the respective financial statement captions are not considered financial instruments or out of scope under authoritative guidance relating to disclosures of the fair value of financial instruments. Financial statement captions excluded from the above table are not considered financial instruments.
The fair values presented above have been determined by using available market information and by applying market valuation methodologies, as described in more detail below.
Fixed Maturities, Held-to-Maturity
The fair values of public fixed maturity securities are generally based on prices from third-party pricing services, which are reviewed for reasonableness; however, for certain public fixed maturity securities and investments in private placement fixed maturity securities, this information is either not available or not reliable. For these public fixed maturity securities, the fair value is based on indicative broker quotes, if available, or determined using a discounted cash flow model or other internally-developed models. For private fixed maturities, fair value is determined using a discounted cash flow model. In determining the fair value of certain fixed maturity securities, the discounted cash flow model may also use unobservable inputs, which reflect the Company's own assumptions about the inputs market participants would use in pricing the security.
Commercial Mortgage and Other Loans
The fair value of most commercial mortgage loans is based upon the present value of the expected future cash flows discounted at the appropriate U.S. Treasury rate or foreign government bond rate (for non-U.S. dollar-denominated loans) plus an appropriate credit spread for similar quality loans. The quality ratings for these loans, a primary determinant of the credit spreads and a significant component of the pricing process, are based on an internally-developed methodology.
Certain commercial mortgage loans are valued incorporating other factors, including the terms of the loans, the principal exit strategies for the loans, prevailing interest rates and credit risk. Other loan valuations are primarily based upon the present value of the expected future cash flows discounted at the appropriate local government bond rate and local market swap rates or credit default swap spreads, plus an appropriate credit spread and liquidity premium. The credit spread and liquidity premium are a significant component of the pricing inputs, and are based upon an internally-developed methodology, which takes into account, among other factors, the credit quality of the loans, the property type of the collateral, the weighted average coupon and the weighted average life of the loans.
Policy Loans
The Company's valuation technique for policy loans is to discount cash flows at the current policy loan coupon rate. Policy loans are fully collateralized by the cash surrender value of underlying insurance policies. As a result, the carrying value of the policy loans approximates the fair value.
Other Long-term Investments
Other long-term investments include investments in joint ventures and limited partnerships. The estimated fair values of these cost method investments are generally based on the Company's NAV as provided in the financial statements of the investees. In certain circumstances, management may adjust the NAV by a premium or discount when it has sufficient evidence to support applying such adjustments. No such adjustments were made as of March 31, 2015 and December 31, 2014.
Short-Term Investments, Cash and Cash Equivalents, Accrued Investment Income and Other Assets
The Company believes that due to the short-term nature of certain assets, the carrying value approximates fair value. These assets include: certain short-term investments which are not securities, are recorded at amortized cost and include quality loans; cash and cash equivalent instruments; accrued investment income; and other assets that meet the definition of financial instruments, including receivables, such as reinsurance recoverables, unsettled trades, accounts receivable and restricted cash.
Policyholders' Account Balances–Investment Contracts
Only the portion of policyholders' account balances related to products that are investment contracts (those without significant mortality or morbidity risk) are reflected in the table above. For fixed deferred annuities, single premium endowments, payout annuities and other similar contracts without life contingencies, fair values are generally derived using discounted projected cash flows based on interest rates that are representative of the Company's financial strength ratings, and hence reflect the Company's own NPR. For guaranteed investment contracts, funding agreements, structured settlements without life contingencies and other similar products, fair values are generally derived using discounted projected cash flows based on interest rates being offered for similar contracts with maturities consistent with those of the contracts being valued. For those balances that can be withdrawn by the customer at any time without prior notice or penalty, the fair value is the amount estimated to be payable to the customer as of the reporting date, which is generally the carrying value. For defined contribution and defined benefit contracts and certain other products, the fair value is the market value of the assets supporting the liabilities.
Securities Sold Under Agreements to Repurchase
The Company receives collateral for selling securities under agreements to repurchase, or pledges collateral under agreements to resell. Repurchase and resale agreements are also generally short-term in nature and, therefore, the carrying amounts of these instruments approximate fair value.
Cash Collateral for Loaned Securities
Cash collateral for loaned securities represents the collateral received or paid in connection with loaning or borrowing securities, similar to the securities sold under agreement to repurchase above. For these transactions, the carrying value of the related asset or liability approximates fair value, as they equal the amount of cash collateral received or paid.
Debt
The fair value of short-term and long-term debt, as well as notes issued by consolidated VIEs, is generally determined by either prices obtained from independent pricing services, which are validated by the Company, or discounted cash flow models. With the exception of the notes issued by consolidated VIEs for which recourse is limited to the assets of the respective VIE and does not extend to the general credit of the Company, the fair values of these instruments consider the Company's own NPR. Discounted cash flow models predominately use market observable inputs such as the borrowing rates currently available to the Company for debt and financial instruments with similar terms and remaining maturities. For commercial paper issuances and other debt with a maturity of less than 90 days, the carrying value approximates fair value.
Other Liabilities
Other liabilities are primarily payables, such as reinsurance payables, unsettled trades, drafts and accrued expense payables. Due to the short term until settlement of most of these liabilities, the Company believes that carrying value approximates fair value.
Separate Account Liabilities–Investment Contracts
Only the portion of separate account liabilities related to products that are investment contracts are reflected in the table above. 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; therefore, carrying value approximates fair value.

Derivative Instruments	14. DERIVATIVE INSTRUMENTS
	Types of Derivative Instruments and Derivative Strategies
	Interest Rate Contracts
	Interest rate swaps, options, and futures are used by the Company to reduce risks from changes in interest rates, manage interest rate exposures arising from mismatches between assets and liabilities (including duration mismatches) and to hedge against changes in the value of assets it owns or anticipates acquiring or selling. Swaps may be attributed to specific assets or liabilities or may be used on a portfolio basis. Under interest rate swaps, the Company agrees with counterparties to exchange, at specified intervals, the difference between fixed-rate and floating-rate interest amounts calculated by reference to an agreed upon notional principal amount.
	The Company also uses swaptions, interest rate caps, and interest rate floors to manage interest rate risk. A swaption is an option to enter into a swap with a forward starting effective date. The Company pays a premium for purchased swaptions and receives a premium for written swaptions. In an interest rate cap, the buyer receives payments at the end of each period in which the interest rate exceeds the agreed strike price. Similarly, in an interest rate floor, the buyer receives payments at the end of each period in which the interest rate is below the agreed strike price. Swaptions and interest rate caps and floors are included in interest rate options.
	In exchange-traded interest rate futures transactions, the Company purchases or sells a specified number of contracts, the values of which are determined by the values of underlying referenced investments, and posts variation margin on a daily basis in an amount equal to the difference in the daily market values of those contracts. The Company enters into exchange-traded futures with regulated futures commission's merchants who are members of a trading exchange.
	Equity Contracts
	Equity index options are contracts which will settle in cash based on differentials in the underlying indices at the time of exercise and the strike price. The Company uses combinations of purchases and sales of equity index options to hedge the effects of adverse changes in equity indices within a predetermined range.
	Total return swaps are contracts whereby the Company agrees with counterparties to exchange, at specified intervals, the difference between the return on an asset (or market index) and LIBOR plus an associated funding spread based on a notional amount. The Company generally uses total return swaps to hedge the effect of adverse changes in equity indices.
	Foreign Exchange Contracts
	Currency derivatives, including currency futures, options, forwards, and swaps, are used by the Company to reduce risks from changes in currency exchange rates with respect to investments denominated in foreign currencies that the Company either holds or intends to acquire or sell, and to hedge the currency risk associated with net investments in foreign operations and anticipated earnings of its foreign operations.
	Under currency forwards, the Company agrees with counterparties to deliver a specified amount of an identified currency at a specified future date. Typically, the price is agreed upon at the time of the contract and payment for such a contract is made at the specified future date. As noted above, the Company uses currency forwards to mitigate the impact of changes in currency exchange rates on U.S. dollar equivalent earnings generated by certain of its non-U.S. businesses, primarily its international insurance and investments operations. The Company executes forward sales of the hedged currency in exchange for U.S. dollars at a specified exchange rate. The maturities of these forwards correspond with the future periods in which the non-U.S. dollar-denominated earnings are expected to be generated. These earnings hedges do not qualify for hedge accounting.
	Under currency swaps, the Company agrees with counterparties to exchange, at specified intervals, the difference between one currency and another at an exchange rate and calculated by reference to an agreed principal amount. Generally, the principal amount of each currency is exchanged at the beginning and termination of the currency swap by each party.
	Credit Contracts
	The Company writes credit default swaps for which it receives a premium to insure credit risk. These are used by the Company to enhance the return on the Company's investment portfolio by creating credit exposure similar to an investment in public fixed maturity cash instruments. With these derivatives the Company sells credit protection on a single name reference, or certain index reference, and in return receives a quarterly premium. This premium or credit spread generally corresponds to the difference between the yield on the referenced names (or an index's referenced names) public fixed maturity cash instruments and swap rates, at the time the agreement is executed. If there is an event of default by the referenced name or one of the referenced names in the index, as defined by the agreement, then the Company is obligated to pay the referenced amount of the contract to the counterparty and receive in return the referenced defaulted security or similar security or (in the case of a credit default index) pay the referenced amount less the auction recovery rate. See credit derivatives written section for further discussion of guarantees. In addition to selling credit protection the Company has purchased credit protection using credit derivatives in order to hedge specific credit exposures in the Company's investment portfolio.
	Other Contracts
	TBAs. The Company uses TBA forward contracts to gain exposure to the investment risk and return of mortgage-backed securities. TBA transactions can help the Company enhance the return on its investment portfolio, and can provide a more liquid and cost effective method of achieving these goals than purchasing or selling individual mortgage-backed pools. Typically, the price is agreed upon at the time of the contract and payment for such a contract is made at a specified future date. Additionally, pursuant to the Company's mortgage dollar roll program, TBAs or mortgage-backed securities are transferred to counterparties with a corresponding agreement to repurchase them at a future date. These transactions do not qualify as secured borrowings and are accounted for as derivatives.
	Loan Commitments. In its mortgage operations, the Company enters into commitments to fund commercial mortgage loans at specified interest rates and other applicable terms within specified periods of time. These commitments are legally binding agreements to extend credit to a counterparty. Loan commitments for loans that will be held for sale are recognized as derivatives and recorded at fair value. The determination of the fair value of loan commitments accounted for as derivatives considers various factors including, among others, terms of the related loan, the intended exit strategy for the loans based upon either securitization valuation models or investor purchase commitments, prevailing interest rates, origination income or expense, and the value of service rights. Loan commitments that relate to the origination of mortgage loans that will be held for investment are not accounted for as derivatives and accordingly are not recognized in the Company's financial statements. See Note 15 for a further discussion of these loan commitments.
	Embedded Derivatives. The Company sells variable annuity products, which may include guaranteed benefit features that are accounted for as embedded derivatives. These embedded derivatives are marked to market through “Realized investment gains (losses), net” based on the change in value of the underlying contractual guarantees, which are determined using valuation models. The Company maintains a portfolio of derivative instruments that is intended to offset certain risks related to the above products' features. The derivatives may include, but are not limited to equity options, total return swaps, interest rate swaptions, caps, floors, and other instruments.
	Synthetic Guarantees. The Company sells synthetic GICs, through both full service and investment-only sales channels, to qualified pension plans. The assets are owned by the trustees of such plans, who invest the assets according to the contract terms agreed to with the Company. The contracts contain a guarantee of a minimum rate of return on participant balances supported by the underlying assets, and a guarantee of liquidity to meet certain participant-initiated withdrawals from the contract. Under U.S. GAAP, these contracts are accounted for as derivatives and recorded at fair value.
	The table below provides a summary of the gross notional amount and fair value of derivatives contracts by the primary underlying, excluding embedded derivatives which are recorded with the associated host. Many derivative instruments contain multiple underlyings. The fair value amounts below represent the gross fair value of derivative contracts prior to taking into account the netting effects of master netting agreements, cash collateral held with the same counterparty and NPR. This netting impact results in total derivative assets of $2,125 million and $1,593 million as of March 31, 2015 and December 31, 2014, respectively, and total derivative liabilities of $109 million and $158 million as of March 31, 2015 and December 31, 2014, respectively, reflected in the Unaudited Interim Consolidated Statements of Financial Position.

	Notional amounts are presented on a gross basis and include derivatives used to offset existing positions.
	Based on notional amounts, most of the Company's derivatives do not qualify for hedge accounting as follows: i) derivatives that economically hedge embedded derivatives do not qualify for hedge accounting because changes in the fair value of the embedded derivatives are already recorded in net income, ii) derivatives that are utilized as macro hedges of the Company's exposure to various risks typically do not qualify for hedge accounting because they do not meet the criteria required under portfolio hedge accounting rules, and iii) synthetic GICs, which are product standalone derivatives that do not qualify as hedging instruments under hedge accounting rules.
	Excludes embedded derivatives which contain multiple underlyings. The fair value of these embedded derivatives was a net liability of $9,448 million as of March 31, 2015 and a net liability of $8,162 million as of December 31, 2014, primarily included in “Future policy benefits.”

For information regarding the rights of offset associated with the derivative assets and liabilities in the table above see “—Counterparty Credit Risk” below. For securities purchased under agreements to resell and securities sold under agreements to repurchase, the Company monitors the value of the securities and maintains collateral, as appropriate, to protect against credit exposure. Where the Company has entered into repurchase and resale agreements with the same counterparty, in the event of default, the Company would generally be permitted to exercise rights of offset. For additional information on the Company's accounting policy for securities repurchase and resale agreements, see Note 2 to the Company's Consolidated Financial Statements included in the Annual Report on Form 10-K for the year ended December 31, 2014.
Cash Flow, Fair Value and Net Investment Hedges
The primary derivative instruments used by the Company in its fair value, cash flow, and net investment hedge accounting relationships are interest rate swaps, currency swaps and currency forwards. These instruments are only designated for hedge accounting in instances where the appropriate criteria are met. The Company does not use futures, options, credit, equity or embedded derivatives in any of its fair value, cash flow or net investment hedge accounting relationships.
The following table provides the financial statement classification and impact of derivatives used in qualifying and non-qualifying hedge relationships, excluding the offset of the hedged item in an effective hedge relationship.

Amounts deferred in “Accumulated other comprehensive income (loss).”
For the three months ending March 31, 2015 and 2014, the ineffective portion of derivatives accounted for using hedge accounting was not material to the Company's results of operations. Also, there were no material amounts reclassified into earnings relating to instances in which the Company discontinued cash flow hedge accounting because the forecasted transaction did not occur by the anticipated date or within the additional time period permitted by the authoritative guidance for the accounting for derivatives and hedging. In addition, there were no instances in which the Company discontinued fair value hedge accounting due to a hedged firm commitment no longer qualifying as a fair value hedge.
Presented below is a rollforward of current period cash flow hedges in “Accumulated other comprehensive income (loss)” before taxes:
			(in millions)
Balance, December 31, 2014			$	206
Net deferred gains (losses) on cash flow hedges from January 1 to March 31, 2015				914
Amount reclassified into current period earnings				-115
Balance, March 31, 2015			$	1,005
Using March 31, 2015 values, it is anticipated that a pre-tax gain of approximately $45 million will be reclassified from AOCI to earnings during the subsequent twelve months ending March 31, 2016, offset by amounts pertaining to the hedged items. As of March 31, 2015, the Company does not have any qualifying cash flow hedges of forecasted transactions other than those related to the variability of the payment or receipt of interest or foreign currency amounts on existing financial instruments. The maximum length of time for which these variable cash flows are hedged is 29 years. Income amounts deferred in AOCI as a result of cash flow hedges are included in “Net unrealized investment gains (losses)” in the Unaudited Interim Consolidated Statements of Comprehensive Income.
For effective net investment hedges, the amounts, before applicable taxes, recorded in the cumulative translation adjustment account within AOCI was $518 million and $501 million as of March 31, 2015 and December 31, 2014, respectively.
Credit Derivatives
Credit derivatives, where the Company has written credit protection on a single name reference, had outstanding notional amounts of $5 million as of both March 31, 2015 and December 31, 2014. These credit derivatives are reported at fair value as an asset of less than $1 million, as of both March 31, 2015 and December 31, 2014. These credit derivatives have an NAIC designation of 2. The Company has also written credit protection on certain index references with notional amounts of $1,280 million and $1,544 million, respectively, reported at fair value as an asset of less than $1 million and a liability of $2 million, respectively, as of March 31, 2015 and December 31, 2014. As of March 31, 2015, these credit derivatives' notionals had the following NAIC ratings: $998 million in NAIC 3, $251 million in NAIC 5, and $31 million in NAIC 6. As of December 31, 2014, the credit derivatives where the Company had written credit protection on an index reference had an NAIC designation of 3. NAIC designations are based on the lowest rated single name reference included in the index.
The Company's maximum amount at risk under these credit derivatives equals the aforementioned notional amounts and assumes the value of the underlying referenced securities become worthless. These single name credit derivatives have maturities of less than 1 year, while the credit protection on the index reference has a maturity of less than 10 years. This excludes a credit derivative related to surplus notes issued by a subsidiary of Prudential Insurance.
The Company also entered into a credit derivative that will require the Company to make certain payments in the event of deterioration in the value of the surplus notes issued by a subsidiary of Prudential Insurance. The notional amount of this credit derivative is $500 million and the fair value as of March 31, 2015 and December 31, 2014 was a liability of $18 million and $4 million, respectively. No collateral was pledged in either period.
In addition to writing credit protection, the Company has purchased credit protection using credit derivatives in order to hedge specific credit exposures in the Company's investment portfolio. As of March 31, 2015 and December 31, 2014, the Company had $626 million and $573 million of outstanding notional amounts, respectively, reported at fair value as a liability of $17 million in both periods.
Counterparty Credit Risk
The Company is exposed to credit-related losses in the event of non-performance by counterparties to financial derivative transactions. The Company manages credit risk by entering into derivative transactions with highly rated major international financial institutions and other creditworthy counterparties, and by obtaining collateral, such as cash and securities, when appropriate. Additionally, limits are set on single party credit exposures which are subject to periodic management review.
The credit exposure of the Company's OTC derivative transactions is represented by the contracts with a positive fair value at the reporting date. To reduce credit exposures, the Company seeks to (i) enter into OTC derivative transactions pursuant to master agreements that provide for a netting of payments and receipts with a single counterparty, and (ii) enter into agreements that allow the use of credit support annexes, which are bilateral rating-sensitive agreements that require collateral postings at established threshold levels. Cleared derivatives are transactions between the Company and a counterparty where the transactions are cleared through a clearinghouse, such that each derivative counterparty is only exposed to the default of the clearinghouse. These cleared transactions require initial and daily variation margin collateral postings and include certain interest rate swaps and credit default swaps entered into on or after June 10, 2013, related to guidelines under the Dodd-Frank Wall Street Reform and Consumer Protection Act. The Company also enters into exchange-traded futures and certain options transactions through regulated exchanges and these transactions are settled on a daily basis, thereby reducing credit risk exposure in the event of non-performance by counterparties to such financial instruments.
Under fair value measurements, the Company incorporates the market's perception of its own and the counterparty's NPR in determining the fair value of the portion of its OTC derivative assets and liabilities that are uncollateralized. Credit spreads are applied to the derivative fair values on a net basis by counterparty. To reflect the Company's own credit spread a proxy based on relevant debt spreads is applied to OTC derivative net liability positions. Similarly, the Company's counterparty's credit spread is applied to OTC derivative net asset positions.
Certain of the Company's derivative agreements with some of its counterparties contain credit-rating related triggers. If the Company's credit rating were to fall below a certain level, the counterparties to the derivative instruments could request termination at the then fair value of the derivative or demand immediate full collateralization on derivative instruments in net liability positions. As of March 31, 2015, there were no net liability derivative positions by counterparty with credit-risk-related contingent features. As such, the Company has not posted any collateral related to these positions and the Company would not be required to post any additional collateral to the counterparties if the credit-risk-related contingent features underlying these agreements had been triggered as of March 31, 2015.

	As discussed in Note 1, from December 18, 2001, the date of demutualization, through December 31, 2014, the Company organized its principal operations into the Financial Services Businesses and the Closed Block Business. As a result of the Class B Repurchase on January 2, 2015, the Company no longer organizes its principal operations into the Financial Services Businesses and the Closed Block Business. The Company operates through four divisions, which together encompass seven reportable segments, and its . Divested businesses, other than the Closed Block division, and businesses that are not sufficiently material to warrant separate disclosure are included in Corporate and Other operations.
	Adjusted Operating Income
	The Company analyzes the operating performance of each segment using “adjusted operating income.” Adjusted operating income does not equate to “Income (loss) from continuing operations before income taxes and equity in earnings of operating joint ventures” or “Net income (loss)” as determined in accordance with U.S. GAAP but is the measure of segment profit or loss used by the Company's chief operating decision maker to evaluate segment performance and allocate resources, and consistent with authoritative guidance, is the measure of segment performance presented below. Adjusted operating income is calculated by adjusting each segment's “Income (loss) from continuing operations before income taxes and equity in earnings of operating joint ventures” for the following items, which are described in greater detail below:
	realized investment gains (losses), net, and related charges and adjustments;
	net investment gains and losses on trading account assets supporting insurance liabilities and changes in experience-rated contractholder liabilities due to asset value changes;
	the contribution to income (loss) of divested businesses that have been or will be sold or exited, including businesses that have been placed in wind down status, but that did not qualify for “discontinued operations” accounting treatment under U.S. GAAP; and
	equity in earnings of operating joint ventures and earnings attributable to noncontrolling interests.
	These items are important to an understanding of overall results of operations. Adjusted operating income is not a substitute for income determined in accordance with U.S. GAAP, and the Company's definition of adjusted operating income may differ from that used by other companies. However, the Company believes that the presentation of adjusted operating income as measured for management purposes enhances the understanding of results of operations by highlighting the results from ongoing operations and the underlying profitability factors of its businesses.
	Realized investment gains (losses), net, and related charges and adjustments
	Realized investment gains (losses), net
	Adjusted operating income excludes “Realized investment gains (losses), net,” except for certain items described below. Significant activity excluded from adjusted operating income includes impairments and credit-related gains and losses from sales of securities, the timing of which depends largely on market credit cycles and can vary considerably across periods, and interest rate-related gains and losses from sales of securities, which are largely subject to the Company's discretion and influenced by market opportunities, as well as the Company's tax and capital profile. Additionally, certain gains and losses pertaining to derivative contracts that do not qualify for hedge accounting treatment are also excluded from adjusted operating income. Trends in the underlying profitability of the Company's businesses can be more clearly identified without the fluctuating effects of these transactions.
	The following table sets forth the significant components of “Realized investment gains (losses), net” that are included in adjusted operating income and, as a result, are reflected as adjustments to “Realized investment gains (losses), net” for purposes of calculating adjusted operating income:
				Three Months Ended March 31,
				2015			2014
	Net gains (losses) from(1):			(in millions)
		Terminated hedges of foreign currency earnings		$	81		$	78
		Current period yield adjustments		$	123		$	124
		Principal source of earnings		$	24		$	14
	In addition to the items in the table above, “Realized investment gains (losses), net, and related charges and adjustments” also includes an adjustment to reflect “Realized investment gains (losses), net” related to divested businesses as results of “Divested businesses,” discussed below.
	Terminated Hedges of Foreign Currency Earnings. The amounts shown in the table above primarily reflect the impact of an intercompany arrangement between Corporate and Other operations and the International Insurance segment, pursuant to which the non-U.S. dollar-denominated earnings in all countries for a particular year, including its interim reporting periods, are translated at fixed currency exchange rates. The fixed rates are determined in connection with a currency hedging program designed to mitigate the risk that unfavorable rate changes will reduce the segment's U.S. dollar equivalent earnings. Pursuant to this program, the Company's Corporate and Other operations may execute forward currency contracts with third parties to sell the net exposure of projected earnings from the hedged currency in exchange for U.S. dollars at a specified exchange rate. The maturities of these contracts correspond with the future periods in which the identified non-U.S. dollar-denominated earnings are expected to be generated. These contracts do not qualify for hedge accounting under U.S. GAAP, so the resulting profits or losses are recorded in “Realized investment gains (losses), net.” When the contracts are terminated in the same period that the expected earnings emerge, the resulting positive or negative cash flow effect is included in adjusted operating income.
	Current Period Yield Adjustments. The Company uses interest rate and currency swaps and other derivatives to manage interest and currency exchange rate exposures arising from mismatches between assets and liabilities, including duration mismatches. For derivative contracts that do not qualify for hedge accounting treatment, the periodic swap settlements, as well as certain other derivative related yield adjustments are recorded in “Realized investment gains (losses), net,” and are included in adjusted operating income to reflect the after-hedge yield of the underlying instruments. In certain instances, when these derivative contracts are terminated or offset before their final maturity, the resulting realized gains or losses are recognized in adjusted operating income over periods that generally approximate the expected terms of the derivatives or underlying instruments in order for adjusted operating income to reflect the after-hedge yield of the underlying instruments. Included in the amounts shown in the table above are gains on certain derivative contracts that were terminated or offset before their final maturity in prior periods of $21 million and $18 million for the three months ended March 31, 2015 and 2014, respectively. Additionally, as of March 31, 2015, there was a $207 million deferred net gain related to certain derivative contracts that were terminated or offset before their final maturity, primarily in the International Insurance segment. Also included in the amounts shown in the table above are fees related to guaranteed investment contracts (“GICs”) of $40 million and $42 million for the three months ended March 31, 2015 and 2014, respectively. Synthetic GICs are accounted for as derivatives under U.S. GAAP and, therefore, these fees are recorded in “Realized investment gains /(losses), net.” See Note 14 for additional information on synthetic GICs.
	Principal Source of Earnings. The Company conducts certain activities for which realized investment gains and losses are a principal source of earnings for its businesses and therefore included in adjusted operating income, particularly within the Company's Asset Management segment. For example, Asset Management's strategic investing business makes investments for sale or syndication to other investors or for placement or co-investment in the Company's managed funds and structured products. The realized investment gains and losses associated with the sale of these strategic investments, as well as related derivative results, are a principal activity for this business and included in adjusted operating income. In addition, the realized investment gains and losses associated with loans originated by the Company's commercial mortgage operations, as well as related derivative results and retained mortgage servicing rights, are a principal activity for this business and included in adjusted operating income.
	Other items reflected as adjustments to Realized investment gains (losses), net
	The following table sets forth certain other items excluded from adjusted operating income and reflected as an adjustment to “Realized investment gains (losses), net” for purposes of calculating adjusted operating income:
				Three Months Ended March 31,
				2015			2014
	Net gains (losses) from:			(in millions)
		Other trading account assets		$	-58		$	22
		Foreign currency exchange movements		$	25		$	231
		Other activities		$	3		$	4
	Other Trading Account Assets. The Company has certain investments in its general account portfolios that are classified as trading. These trading investments are carried at fair value and included in “Other trading account assets, at fair value” on the Company's Unaudited Interim Consolidated Statements of Financial Position. Realized and unrealized gains and losses for these investments are recorded in “Other income.” Consistent with the exclusion of realized investment gains and losses with respect to other investments managed on a consistent basis, the net gains or losses on these investments are excluded from adjusted operating income.
	Foreign Currency Exchange Movements. The Company has certain assets and liabilities for which, under U.S. GAAP, the changes in value, including those associated with changes in foreign currency exchange rates during the period, are recorded in “Other income.” To the extent the foreign currency exposure on these assets and liabilities is economically hedged or considered part of the Company's capital funding strategies for its international subsidiaries, the change in value included in “Other income” is excluded from adjusted operating income. The amount in the table above for the three months ended March 31, 2014 was largely driven by non-yen denominated insurance liabilities in the Company's Japanese insurance operations. The insurance liabilities are supported by investments denominated in corresponding currencies, including a significant portion designated as available-for-sale. While these non-yen denominated assets and liabilities are economically hedged, unrealized gains and losses on available-for-sale investments, including those arising from foreign currency exchange rate movements, are recorded in “Accumulated other comprehensive income (loss)” under U.S. GAAP, while the non-yen denominated liabilities are re-measured for foreign currency exchange rate movements, and the related change in value is recorded in earnings within “Other income.” Due to this non-economic volatility that has been reflected in U.S. GAAP earnings, the change in value recorded within “Other income” is excluded from adjusted operating income.
	As a result of continued growth in these portfolios, we have implemented a new structure in Gibraltar Life that disaggregates the U.S. and Australian dollar-denominated businesses into separate divisions, each with its own functional currency that aligns with the underlying products and investments. The new structure is effective for financial reporting beginning in the first quarter 2015 and will minimize future volatility in reported U.S. GAAP earnings arising from foreign currency remeasurement.
	Other Activities. The Company excludes certain other items from adjusted operating income that are consistent with similar adjustments described above. The significant items within other activities shown in the table above included the following:
	In connection with disputes arising out of the Chapter 11 bankruptcy petition filed by Lehman Brothers Holdings Inc., the Company previously recorded losses related to a portion of its counterparty exposure on derivative transactions it had previously held with Lehman Brothers and its affiliates. The Company recorded no estimated recoveries related to this matter for the three months ended March 31, 2015 and $7 million for the three months ended March 31, 2014. These recoveries are recorded within “Other income” within the Company's Corporate and Other operations. Consistent with the exclusion of credit-related losses recorded in “Realized investment gains (losses), net,” the impact of this estimated recovery is excluded from adjusted operating income.
	The Company records valuation adjustments for non-performance risk (“NPR”) that relates to the uncollateralized portion of certain derivative contracts between a subsidiary of the Company and third parties and liquidity risk associated with certain derivatives. These adjustments are recorded within “Other income.” Consistent with the exclusion of the mark-to-market on derivatives recorded in “Realized investment gains (losses), net,” the impact of these risks is excluded from adjusted operating income. The net impact of these risks was to exclude from adjusted operating income a net gain of $3 million and a net loss of $2 million for the three months ended March 31, 2015 and 2014, respectively.
	Related charges
	Charges that relate to realized investment gains and losses are also excluded from adjusted operating income, and include the following:
	The portion of the amortization of DAC, VOBA, unearned revenue reserves and deferred sales inducements for certain products that is related to net realized investment gains and losses.
	Policyholder dividends and interest credited to policyholders' account balances that relate to certain life policies that pass back certain realized investment gains and losses to the policyholder, and reserves for future policy benefits for certain policies that are affected by net realized investment gains and losses.
	Market value adjustments paid or received upon a contractholder's surrender of certain of the Company's annuity products as these amounts mitigate the net realized investment gains or losses incurred upon the disposition of the underlying invested assets.
	Investment gains and losses on trading account assets supporting insurance liabilities and changes in experience-rated contractholder liabilities due to asset value changes
	Certain products included in the Retirement and International Insurance segments are experience-rated in that investment results associated with these products are expected to ultimately accrue to contractholders. The majority of investments supporting these experience-rated products are classified as trading and are carried at fair value, with realized and unrealized gains and losses reported in “Other income.” To a lesser extent, these experience-rated products are also supported by derivatives and commercial mortgage and other loans. The derivatives are carried at fair value, with realized and unrealized gains and losses reported in “Realized investment gains (losses), net.” The commercial mortgage and other loans are carried at unpaid principal, net of unamortized discounts and an allowance for losses, with gains and losses on sales and changes in the valuation allowance for commercial mortgage and other loans reported in “Realized investment gains (losses), net.”
	Adjusted operating income excludes net investment gains and losses on trading account assets supporting insurance liabilities, which is consistent with the exclusion of realized investment gains and losses with respect to other investments supporting insurance liabilities managed on a consistent basis. In addition, to be consistent with the historical treatment of charges related to realized investment gains and losses on investments, adjusted operating income also excludes the change in contractholder liabilities due to asset value changes in the pool of investments (including changes in the fair value of commercial mortgage and other loans) supporting these experience-rated contracts, which are reflected in “Interest credited to policyholders' account balances.” These adjustments are in addition to the exclusion from adjusted operating income of net investment gains and losses on the related derivatives and commercial mortgage and other loans through “Realized investment gains (losses), net, and related charges and adjustments,” as discussed above. The result of this approach is that adjusted operating income for these products includes net fee revenue and interest spread the Company earns on these experience-rated contracts, and excludes changes in fair value of the pool of investments, both realized and unrealized, that are expected to ultimately accrue to the contractholders.
	Divested businesses
	The contribution to income (loss) of divested businesses that have been or will be sold or exited, including businesses that have been placed in wind down, but that did not qualify for “discontinued operations” accounting treatment under U.S. GAAP, are excluded from adjusted operating income as the results of divested businesses are not considered relevant to understanding the Company's ongoing operating results.
	As discussed in Note 1, the Class B Repurchase on January 2, 2015 resulted in the elimination of the separate reporting of the Company's former Financial Services Businesses and Closed Block Business. As a result of the Class B Repurchase, for the three months ended March 31, 2015, the Closed Block division, which is comprised of the Closed Block segment, has been accounted for as a divested business because it consists primarily of participating insurance and annuity products that the Company ceased selling at demutualization in 2001. For reporting periods through December 31, 2014, the Closed Block segment was reported as the Closed Block Business and was analyzed using U.S. GAAP rather than adjusted operating income. Both the current reporting of the Closed Block division and the historic reporting of the Closed Block Business exclude its results from adjusted operating income.
	Equity in earnings of operating joint ventures and earnings attributable to noncontrolling interests
	Equity in earnings of operating joint ventures, on a pre-tax basis, are included in adjusted operating income as these results are a principal source of earnings. These earnings are reflected on a U.S. GAAP basis on an after-tax basis as a separate line on the Company's Unaudited Interim Consolidated Statements of Operations.
	Earnings attributable to noncontrolling interests are excluded from adjusted operating income. Earnings attributable to noncontrolling interests represents the portion of earnings from consolidated entities that relates to the equity interests of minority investors, and are reflected on a U.S. GAAP basis as a separate line on the Company's Unaudited Interim Consolidated Statements of Operations.
	The table below reconciles adjusted operating income before income taxes to income from continuing operations before income taxes and equity in earnings of operating joint ventures.

Commitments And Guarantees And Contingent Liabilities [Abstract]
Commitments and Guarantees, Contingent Liabilities and Litigation and Regulatory Matters	15.       COMMITMENTS AND GUARANTEES, CONTINGENT LIABILITIES AND LITIGATION AND REGULATORY MATTERS
	Commitments and Guarantees
	Commercial Mortgage Loan Commitments
						March 31,			December 31,
						2015			2014
					(in millions)
			Total outstanding mortgage loan commitments		$	2,388		$	2,442
			Portion of commitment where prearrangement to sell to investor exists		$	657		$	958
	In connection with the Company's commercial mortgage operations, it originates commercial mortgage loans. Commitments for loans that will be held for sale are recognized as derivatives and recorded at fair value. In certain of these transactions, the Company pre-arranges that it will sell the loan to an investor, including to government sponsored entities as discussed below, after the Company funds the loan.
	Commitments to Purchase Investments (excluding Commercial Mortgage Loans)
					March 31,			December 31,
					2015			2014
				(in millions)
	Expected to be funded from the general account and other operations outside the
		separate accounts(1)		$	3,980		$	4,883
	Expected to be funded from separate accounts			$	274		$	28
	(1) Includes a remaining commitment of $160 million and $194 million at March 31, 2015 and December 31, 2014, respectively, related to the Company's agreement to co-invest with the Fosun Group (“Fosun”) in a private equity fund, managed by Fosun, for the Chinese marketplace.
	The Company has other commitments to purchase or fund investments, some of which are contingent upon events or circumstances not under the Company's control, including those at the discretion of the Company's counterparties. The Company anticipates a portion of these commitments will ultimately be funded from its separate accounts.
	Indemnification of Securities Lending Transactions
					March 31,			December 31,
					2015			2014
					(in millions)
			Indemnification provided to mutual fund and separate account clients for securities lending		$	14,419		$	14,334
			Fair value of related collateral associated with above indemnifications		$	14,816		$	14,740
			Accrued liability associated with guarantee		$	0		$	0
	In the normal course of business, the Company may facilitate securities lending transactions on behalf of mutual funds and separate accounts for which the Company is the investment advisor and/or the asset manager. In certain of these arrangements, the Company has provided an indemnification to the mutual funds or separate accounts to hold them harmless against losses caused by counterparty (i.e., borrower) defaults associated with the securities lending activity facilitated by the Company. Collateral is provided by the counterparty to the mutual fund or separate account at the inception of the loan equal to or greater than 102% of the fair value of the loaned securities and the collateral is maintained daily at 102% or greater of the fair value of the loaned securities. The Company is only at risk if the counterparty to the securities lending transaction defaults and the value of the collateral held is less than the value of the securities loaned to such counterparty. The Company believes the possibility of any payments under these indemnities is remote.
	Credit Derivatives Written
	As discussed further in Note 14, the Company writes credit derivatives under which the Company is obligated to pay the counterparty the referenced amount of the contract and receive in return the defaulted security or similar security.
	Guarantees of Asset Values
				March 31,			December 31,
				2015			2014
				(in millions)
		Guaranteed value of third parties' assets		$	73,770		$	74,707
		Fair value of collateral supporting these assets		$	76,080		$	76,711
		Asset associated with guarantee, carried at fair value		$	6		$	6
	Certain contracts underwritten by the Retirement segment include guarantees related to financial assets owned by the guaranteed party. These contracts are accounted for as derivatives and carried at fair value. The collateral supporting these guarantees is not reflected on the Company's balance sheet.
	Guarantees of Credit Enhancements
						March 31,			December 31,
						2015			2014
					(in millions)
		Guarantees of credit enhancements of debt instruments associated with commercial
			real estate assets		$	5		$	5
		Fair value of properties and associated tax credits that secure the guarantee			$	7		$	8
		Accrued liability associated with guarantee			$	0		$	0
	The Company arranges for credit enhancements of certain debt instruments that provide financing primarily for affordable multi-family real estate assets, including certain tax-exempt bond financings. The credit enhancements provide assurances to the debt holders as to the timely payment of amounts due under the debt instruments. The remaining contractual maturities for these guarantees are up to fifteen years. The Company's obligations to reimburse required credit enhancement payments are secured by mortgages on the related real estate. The Company receives certain ongoing fees for providing these enhancement arrangements and anticipates the extinguishment of its obligation under these enhancements prior to maturity through the aggregation and transfer of its positions to a substitute enhancement provider.
	Indemnification of Serviced Mortgage Loans
					March 31,			December 31,
					2015			2014
					(in millions)
		Maximum exposure under indemnification agreements for mortgage loans
			serviced by the Company		$	1,281		$	1,248
		First-loss exposure portion of above			$	395		$	388
		Accrued liability associated with guarantees			$	17		$	16
	As part of the commercial mortgage activities of the Company's Asset Management segment, the Company provides commercial mortgage origination, underwriting and servicing for certain government sponsored entities, such as Fannie Mae and Freddie Mac. The Company has agreed to indemnify the government sponsored entities for a portion of the credit risk associated with certain of the mortgages it services through a delegated authority arrangement. Under these arrangements, the Company originates multi-family mortgages for sale to the government sponsored entities based on underwriting standards they specify, and makes payments to them for a specified percentage share of losses they incur on certain loans serviced by the Company. The Company's percentage share of losses incurred generally varies from 2% to 20% of the loan balance, and is typically based on a first-loss exposure for a stated percentage of the loan balance, plus a shared exposure with the government sponsored entity for any losses in excess of the stated first-loss percentage, subject to a contractually specified maximum percentage. The Company services $10,207 million of mortgages subject to these loss-sharing arrangements as of March 31, 2015, all of which are collateralized by first priority liens on the underlying multi-family residential properties. As of March 31, 2015, these mortgages had an average debt service coverage ratio of 2.08 times and an average loan-to-value ratio of 62%. The Company had no losses related to indemnifications that were settled for the three months ending March 31, 2015 and 2014, respectively.
	Other Guarantees
					March 31,			December 31,
					2015			2014
					(in millions)
	Other guarantees where amount can be determined				$	312		$	331
	Accrued liability for other guarantees and indemnifications				$	4		$	5
	The Company is also subject to other financial guarantees and indemnity arrangements. The Company has provided indemnities and guarantees related to acquisitions, dispositions, investments and other transactions that are triggered by, among other things, breaches of representations, warranties or covenants provided by the Company. These obligations are typically subject to various time limitations, defined by the contract or by operation of law, such as statutes of limitation. In some cases, the maximum potential obligation is subject to contractual limitations, while in other cases such limitations are not specified or applicable. Included above are $304 million and $323 million as of March 31, 2015 and December 31, 2014, respectively, of yield maintenance guarantees related to certain investments the Company sold. The Company does not expect to make any payments on these guarantees and is not carrying any liabilities associated with these guarantees.
	Since certain of these obligations are not subject to limitations, it is not possible to determine the maximum potential amount due under these guarantees. The accrued liabilities identified above do not include retained liabilities associated with sold businesses.
	Contingent Liabilities
	On an ongoing basis, the Company's internal supervisory and control functions review the quality of sales, marketing and other customer interface procedures and practices and may recommend modifications or enhancements. From time to time, this review process results in the discovery of product administration, servicing or other errors, including errors relating to the timing or amount of payments or contract values due to customers. In certain cases, if appropriate, the Company may offer customers remediation and may incur charges, including the cost of such remediation, administrative costs and regulatory fines.
The Company is subject to the laws and regulations of states and other jurisdictions concerning the identification, reporting and escheatment of unclaimed or abandoned funds, and is subject to audit and examination for compliance with these requirements. For additional discussion of these matters, see “Litigation and Regulatory Matters” below.
It is possible that the results of operations or the cash flow of the Company in a particular quarterly or annual period could be materially affected as a result of payments in connection with the matters discussed above or other matters depending, in part, upon the results of operations or cash flow for such period. Management believes, however, that ultimate payments in connection with these matters, after consideration of applicable reserves and rights to indemnification, should not have a material adverse effect on the Company's financial position.
Litigation and Regulatory Matters
The Company is subject to legal and regulatory actions in the ordinary course of its businesses. Pending legal and regulatory actions include proceedings relating to aspects of the Company's businesses and operations that are specific to it and proceedings that are typical of the businesses in which it operates, including in both cases businesses that have been either divested or placed in wind-down status. Some of these proceedings have been brought on behalf of various alleged classes of complainants. In certain of these matters, the plaintiffs are seeking large and/or indeterminate amounts, including punitive or exemplary damages. The outcome of litigation or a regulatory matter, and the amount or range of potential loss at any particular time, is often inherently uncertain.
The Company establishes accruals for litigation and regulatory matters when it is probable that a loss has been incurred and the amount of that loss can be reasonably estimated. For litigation and regulatory matters where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established but the matter, if material, is disclosed, including matters discussed below. The Company estimates that as of March 31, 2015, the aggregate range of reasonably possible losses in excess of accruals established for those litigation and regulatory matters for which such an estimate currently can be made is less than $250 million. Any estimate is not an indication of expected loss, if any, or the Company's maximum possible loss exposure on such matters. The Company reviews relevant information with respect to its litigation and regulatory matters on a quarterly and annual basis and updates its accruals, disclosures and estimates of reasonably possible loss based on such reviews.
The following discussion of litigations and regulatory matters provides an update of those matters discussed in Note 23 to the Company's Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014, and should be read in conjunction with the complete descriptions provided in the Form 10-K.
Individual Annuities, Individual Life and Group Insurance
Lederman v. PFI
In March 2015, the court granted the Company summary judgment and dismissed with prejudice the complaint of the remaining plaintiff with claims against the Company.
Other Matters
Bouder v. PFI
In February 2015, the federal District Court for New Jersey granted in part, and denied in part, plaintiffs' renewed class certification motion. It certified for class treatment plaintiffs' wage payment claims which include allegations that the Company made improper deductions from the wages of its former common law agents in California, New York, and Pennsylvania, and its financial services associates in California and New York. The Court denied plaintiffs' attempt to certify a class based on the Company's alleged failure to pay overtime to its former common law agents and its financial services associates in California, Illinois, New York and Pennsylvania. In March 2015, the Company filed a motion requesting that the Court reconsider its decision to partially grant plaintiffs' renewed class certification motion with regard to its former common law agents.
Residential Mortgage-Backed Securities Litigation
PICA et al. v. Bank of America National Association & Merrill Lynch & Co., Inc., et al.―In April 2015, this lawsuit was settled.
PICA et al. v. Countrywide Financial Corp., et al.―In April 2015, this lawsuit was settled.
RMBS Trustee
PICA et al. v. Bank of New York Mellon―In March 2015, defendants filed a motion to dismiss the amended complaint.
PICA et al. v. Citibank N.A.―In February 2015, defendants filed a motion to dismiss the amended complaint.
PICA et al. v. HSBC, et al.―In January 2015, defendants filed a motion to dismiss the amended complaint.
PICA et al. v. U.S. Bank National Association―In February 2015, defendants filed a motion to dismiss the amended complaint.
Summary
The Company's litigation and regulatory matters are subject to many uncertainties, and given their complexity and scope, their outcome cannot be predicted. It is possible that the Company's results of operations or cash flow in a particular quarterly or annual period could be materially affected by an ultimate unfavorable resolution of pending litigation and regulatory matters depending, in part, upon the results of operations or cash flow for such period. In light of the unpredictability of the Company's litigation and regulatory matters, it is also possible that in certain cases an ultimate unfavorable resolution of one or more pending litigation or regulatory matters could have a material adverse effect on the Company's financial position. Management believes, however, that, based on information currently known to it, the ultimate outcome of all pending litigation and regulatory matters, after consideration of applicable reserves and rights to indemnification, is not likely to have a material adverse effect on the Company's financial position.

Business and Basis of Presentation [Abstract]
Basis of Presentation, Policy	Basis of Presentation
	As a result of the Class B Repurchase and resulting elimination of the separation of the Financial Services Businesses and the Closed Block Business, these Unaudited Interim Consolidated Financial Statements refer to the divisions and segments of the Company that formerly comprised the Financial Services Businesses as “PFI excluding Closed Block division” and refer to the operations that were formerly included in the Closed Block Business as the “Closed Block division,” except as otherwise noted. Closed Block Business results were associated with the Company's Class B Stock for periods prior to January 1, 2015.
	The Unaudited Interim Consolidated Financial Statements include the accounts of Prudential Financial, entities over which the Company exercises control, including majority-owned subsidiaries and minority-owned entities such as limited partnerships in which the Company is the general partner, and variable interest entities in which the Company is considered the primary beneficiary. See Note 5 for more information on the Company's consolidated variable interest entities. 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, 2014.
	The Company's Gibraltar Life Insurance Company, Ltd. (“Gibraltar Life”) consolidated operations use a November 30 fiscal year end for purposes of inclusion in the Company's Consolidated Financial Statements; therefore, the Unaudited Interim Consolidated Financial Statements as of March 31, 2015, include the assets and liabilities of Gibraltar Life and its results of operations as of, and for the three months ended, February 28, 2015, respectively.
Use of Estimates, Policy	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; value of business acquired (“VOBA”) and its amortization; amortization of sales inducements; measurement of goodwill and any related impairment; valuation of investments including derivatives and the recognition of other-than-temporary impairments; future policy benefits including guarantees; pension and other postretirement benefits; provision for income taxes and valuation of deferred tax assets; and reserves for contingent liabilities, including reserves for losses in connection with unresolved legal matters.
Reclassifications, Policy	Reclassifications
	Certain amounts in prior periods have been reclassified to conform to the current period presentation.

Other primarily represents reclassifications of certain assets between reporting categories and eliminations of intercompany separate account investments.
Transfers into or out of Level 3 are generally reported as the value as of the beginning of the quarter in which the transfer occurs.
Unrealized gains or losses related to assets still held at the end of the period do not include amortization or accretion of premiums and discounts.
Separate account assets represent segregated funds that are invested for certain customers. Investment risks associated with market value changes are borne by the customers, except to the extent of minimum guarantees made by the Company with respect to certain accounts. Separate account liabilities are not included in the above table as they are reported at contract value and not fair value in the Company's Unaudited Interim Consolidated Statements of Financial Position.
Prior period amounts have been reclassified to conform to current period presentation.

	Conversely, the impact of a decrease in input would have the opposite impact for the fair value as that presented in the table.
	Represents multiples of earnings before interest, taxes, depreciation and amortization (“EBITDA”), and are amounts used when the reporting entity has determined that market participants would use such multiples when pricing the investments.
	Future policy benefits primarily represent general account liabilities for the optional living benefit features of the Company's variable annuity contracts which are accounted for as embedded derivatives. Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.
	Lapse rates are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates are also generally assumed to be lower for the period where surrender charges apply.
	To reflect NPR, the Company incorporates an additional spread over LIBOR into the discount rate used in the valuation of individual living benefit contracts in a liability position and generally not to those in a contra-liability position. The NPR spread reflects the financial strength ratings of the Company as these are insurance liabilities and senior to debt. The additional spread over LIBOR is determined by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium.
	The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration, and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status, and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal.
	The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions may vary based on the product type, contractholder age, tax status, and withdrawal timing. The fair value of the liability will generally increase the closer the withdrawal rate is to 100%.
	Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 35 to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table.

	Notional amounts are presented on a gross basis and include derivatives used to offset existing positions.
	Based on notional amounts, most of the Company's derivatives do not qualify for hedge accounting as follows: i) derivatives that economically hedge embedded derivatives do not qualify for hedge accounting because changes in the fair value of the embedded derivatives are already recorded in net income, ii) derivatives that are utilized as macro hedges of the Company's exposure to various risks typically do not qualify for hedge accounting because they do not meet the criteria required under portfolio hedge accounting rules, and iii) synthetic GICs, which are product standalone derivatives that do not qualify as hedging instruments under hedge accounting rules.
	Excludes embedded derivatives which contain multiple underlyings. The fair value of these embedded derivatives was a net liability of $9,448 million as of March 31, 2015 and a net liability of $8,162 million as of December 31, 2014, primarily included in “Future policy benefits.”

General Description of employee benefit plans	The Company has funded and non-funded non-contributory defined benefit pension plans, which cover substantially all of its employees. For some employees, benefits are based on final average earnings and length of service, while benefits for other employees are based on an account balance that takes into consideration age, service and earnings during their career. The Company provides certain health care and life insurance benefits for its retired employees, their beneficiaries and covered dependents (“other postretirement benefits”). The health care plan is contributory; the life insurance plan is non-contributory. Substantially all of the Company’s U.S. employees may become eligible to receive other postretirement benefits if they retire after age 55 with at least 10 years of service or under certain circumstances after age 50 with at least 20 years of continuous service. Net periodic (benefit) cost included in “General and administrative expenses” includes the following components:

Since the valuation methodology for these liabilities uses a range of inputs that vary at the contract level over the cash flow projection period, presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation.
[3]	Lapse rates are adjusted at the contract level based on the in-the-moneyness of the living benefit and reflect other factors, such as the applicability of any surrender charges. Lapse rates are reduced when contracts are more in-the-money. Lapse rates are also generally assumed to be lower for the period where surrender charges apply.
[4]	To reflect NPR, the Company incorporates an additional spread over LIBOR into the discount rate used in the valuation of individual living benefit contracts in a liability position and generally not to those in a contra-liability position. The NPR spread reflects the financial strength ratings of the Company as these are insurance liabilities and senior to debt. The additional spread over LIBOR is determined by utilizing the credit spreads associated with issuing funding agreements, adjusted for any illiquidity risk premium.
[5]	The utilization rate assumption estimates the percentage of contracts that will utilize the benefit during the contract duration, and begin lifetime withdrawals at various time intervals from contract inception. The remaining contractholders are assumed to either begin lifetime withdrawals immediately or never utilize the benefit. Utilization assumptions may vary by product type, tax status, and age. The impact of changes in these assumptions is highly dependent on the product type, the age of the contractholder at the time of the sale, and the timing of the first lifetime income withdrawal.
[6]	The withdrawal rate assumption estimates the magnitude of annual contractholder withdrawals relative to the maximum allowable amount under the contract. These assumptions may vary based on the product type, contractholder age, tax status, and withdrawal timing. The fair value of the liability will generally increase the closer the withdrawal rate is to 100%.
[7]	Range reflects the mortality rate for the vast majority of business with living benefits, with policyholders ranging from 35 to 90 years old. While the majority of living benefits have a minimum age requirement, certain benefits do not have an age restriction. This results in contractholders for certain benefits with mortality rates approaching 0%. Based on historical experience, the Company applies a set of age and duration specific mortality rate adjustments compared to standard industry tables. A mortality improvement assumption is also incorporated into the overall mortality table.

[1]	Other primarily represents reclassifications of certain assets between reporting categories and eliminations of intercompany separate account investments.
[2]	Transfers into or out of Level 3 are generally reported as the value as of the beginning of the quarter in which the transfer occurs.
[3]	Unrealized gains or losses related to assets still held at the end of the period do not include amortization or accretion of premiums and discounts.
[4]	Prior period amounts have been reclassified to conform to current period presentation.
[5]	Separate account assets represent segregated funds that are invested for certain customers. Investment risks associated with market value changes are borne by the customers, except to the extent of minimum guarantees made by the Company with respect to certain accounts. Separate account liabilities are not included in the above table as they are reported at contract value and not fair value in the Company’s Unaudited Interim Consolidated Statements of Financial Position.

[1]	Notional amounts are presented on a gross basis and include derivatives used to offset existing positions.
[2]	Excludes embedded derivatives which contain multiple underlyings. The fair value of these embedded derivatives was a net liability of $9,448 million as of March 31, 2015 and a net liability of $8,162 million as of December 31, 2014, primarily included in “Future policy benefits.”
[3]	Based on notional amounts, most of the Company’s derivatives do not qualify for hedge accounting as follows: i) derivatives that economically hedge embedded derivatives do not qualify for hedge accounting because changes in the fair value of the embedded derivatives are already recorded in net income, ii) derivatives that are utilized as macro hedges of the Company’s exposure to various risks typically do not qualify for hedge accounting because they do not meet the criteria required under portfolio hedge accounting rules, and iii) synthetic GICs, which are product standalone derivatives that do not qualify as hedging instruments under hedge accounting rules.
