(Some amounts may not reconcile due to rounding.) During the third quarter of 2022, the Company re-designated a portion of its fixed maturity securities from its fixed maturity – available for sale portfolio to its fixed maturity – held to maturity portfolio. The fair value of the securities reclassified at the date of transfer was $722 million, net of allowance for current expected credit losses, which was subsequently recognized as the new amortized cost basis. As of June 30, 2023, these securities had an unrealized loss of $46 million, which remained in accumulated other comprehensive income (“AOCI”) on the balance sheet and will be amortized into income through an adjustment to the yields of the underlying securities over the remaining life of the securities. The fair values of these securities incorporate the use of significant unobservable inputs and therefore are classified as Level 3 within the fair value hierarchy. The Company evaluated fixed maturity securities classified as held to maturity for current expected credit losses as of June 30, 2023 utilizing risk characteristics of each security, including credit rating, remaining time to maturity, adjusted for prepayment considerations, and subordination level, and applying default and recovery rates, which include the incorporation of historical credit loss experience and macroeconomic forecasts, to develop an estimate of current expected credit losses. These fixed maturities classified as held to maturity are of a high credit quality and are all rated investment grade as of June 30, 2023. The changes in net unrealized appreciation (depreciation) for the Company’s investments are as follows:

(Some amounts may not reconcile due to rounding.) The aggregate fair value and gross unrealized losses related to fixed maturity securities - available for sale in an unrealized loss position at June 30, 2023 were $20.7 billion and $1.9 billion, respectively. The fair value of securities for the single issuer (the United States government), whose securities comprised the largest unrealized loss position at June 30, 2023, amounted to less than 4.4% of the overall fair value of the Company’s fixed maturity securities available for sale. The fair value of the securities for the issuer with the second largest unrealized loss position at June 30, 2023 comprised less than 0.8% of the Company’s fixed maturity securities available for sale. In addition, as indicated on the above table, there was no significant concentration of unrealized losses in any one market sector. The $252 million of unrealized losses related to fixed maturity securities - available for sale that have been in an unrealized loss position for less than one year were generally comprised of domestic and foreign corporate securities, agency residential and non-agency residential mortgage-backed securities and asset-backed securities. Of these unrealized losses, $221 million were related to securities that were rated investment grade by at least one nationally recognized rating agency. The $1.6 billion of unrealized losses related to fixed maturity securities - available for sale in an unrealized loss position for more than one year related primarily to foreign and domestic corporate securities, agency residential mortgage-backed securities, foreign government securities, commercial mortgage-backed securities and asset-backed securities. Of these unrealized losses, $1.56 billion were related to securities that were rated investment grade by at least one nationally recognized rating agency. In all instances, there were no projected cash flow shortfalls to recover the full book value of the investments and the related interest obligations. The mortgage-backed securities still have excess credit coverage and are current on interest and principal payments. Based upon the Company’s current evaluation of securities in an unrealized loss position as of June 30, 2023, the unrealized losses are due to changes in interest rates and non-issuer-specific credit spreads and are not credit-related. In addition, the contractual terms of these securities do not permit these securities to be settled at a price less than their amortized cost. The Company, given the size of its investment portfolio and capital position, does not have the intent to sell these securities; and it is more likely than not that the Company will not have to sell the security before recovery of its cost basis. In addition, all securities currently in an unrealized loss position are current with respect to principal and interest payments. The tables below display the aggregate fair value and gross unrealized depreciation of fixed maturity securities - available for sale by security type and contractual maturity, in each case subdivided according to length of time that individual securities had been in a continuous unrealized loss position for the periods indicated:

(Some amounts may not reconcile due to rounding.) The aggregate fair value and gross unrealized losses related to fixed maturity - available for sale investments in an unrealized loss position at December 31, 2022 were $19.6 billion and $2.0 billion, respectively.

The fair value of the securities for the issuer with the second largest unrealized loss comprised less than 0.2% of the Company’s fixed maturity securities - available for sale. In addition, as indicated on the above table, there was no significant concentration of unrealized losses in any one market sector. The $1.2 billion of unrealized losses related to fixed maturity securities - available for sale that have been in an unrealized loss position for less than one year were generally comprised of domestic and foreign corporate securities, asset-backed securities, agency residential mortgage-backed securities and foreign government securities. Of these unrealized losses, $1.1 billion were related to securities that were rated investment grade by at least one nationally recognized rating agency.

In all instances, there were no projected cash flow shortfalls to recover the full book value of the investments and the related interest obligations. The mortgage-backed securities still have excess credit coverage and are current on interest and principal payments. The components of net investment income are presented in the table below for the periods indicated:

(Some amounts may not reconcile due to rounding.) The Company records results from limited partnership investments on the equity method of accounting with changes in value reported through net investment income. The net investment income from limited partnerships is dependent upon the Company’s share of the net asset values (“NAVs”) of interests underlying each limited partnership. Due to the timing of receiving financial information from these partnerships, the results are generally reported on a one month or quarter lag. If the Company determines there has been a significant decline in value of a limited partnership during this lag period, a loss will be recorded in the period in which the Company identifies the decline. The Company had contractual commitments to invest up to an additional $2.8 billion in limited partnerships and private placement loan securities at June 30, 2023. These commitments will be funded when called in accordance with the partnership and loan agreements, which have investment periods that expire, unless extended, through 2027. During the fourth quarter of 2022, the Company entered into corporate-owned life insurance (COLI) policies, which are primarily invested in liquid credit, equity, and other assets, including alternative assets. The COLI policies are carried within other invested assets at policy cash surrender value of $968 million and $939 million as of June 30, 2023 and December 31, 2022, respectively. Variable Interest Entities The Company is engaged with various special purpose entities and other entities that are deemed to be VIEs primarily as an investor through normal investment activities but also as an investment manager. A VIE is an entity that either has investors that lack certain essential characteristics of a controlling financial interest, such as simple majority kick-out rights, or lacks sufficient funds to finance its own activities without financial support provided by other entities. The Company performs ongoing qualitative assessments of its VIEs to determine whether the Company has a controlling financial interest in the VIE and therefore is the primary beneficiary. The Company is deemed to have a controlling financial interest when it has both the ability to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. Based on the Company’s assessment, if it determines it is the primary beneficiary, the Company consolidates the VIE in the Company’s Consolidated Financial Statements. As of June 30, 2023 and December 31, 2022, the Company did not hold any securities for which it is the primary beneficiary. The Company, through normal investment activities, makes passive investments in general and limited partnerships and other alternative investments. For these non-consolidated VIEs, the Company has determined it is not the primary beneficiary as it has no ability to direct activities that could significantly affect the economic performance of the investments. The Company’s maximum exposure to loss as of June 30, 2023 and December 31, 2022 is limited to the total carrying value of $4.3 billion and $4.1 billion, respectively, which are included in general and limited partnerships and other alternative investments in Other Invested Assets in the Company's Consolidated Balance Sheets. As of June 30, 2023, the Company has outstanding commitments totaling $2.2 billion whereby the Company is committed to fund these investments and may be called by the partnership during the commitment period to fund the purchase of new investments and partnership expenses. These investments are generally of a passive nature in that the Company does not take an active role in management. In addition, the Company makes passive investments in structured securities issued by VIEs for which the Company is not the manager. These investments are included in asset-backed securities, which includes collateralized loan obligations and are classified as fixed maturities, available for sale. The Company has not provided financial or other support with respect to these investments other than its original investment. For these investments, the Company determined it is not the primary beneficiary due to the relative size of the Company’s investment in comparison to the principal amount of the structured securities issued by the VIEs, credit subordination that reduces the Company’s obligation to absorb losses or right to receive benefits or the Company’s inability to direct the activities that most significantly impact the economic performance of the VIEs. The Company’s maximum exposure to loss on these investments is limited to the amount of the Company’s investment.
