(a)Private Credit - The limited partnerships described in this category employ various investment strategies, generally providing direct lending or other forms of debt financing including first-lien, second-lien, mezzanine, and subordinated loans. The limited partnerships have credit exposure to corporates, physical assets, and/or financial assets within a variety of industries (including manufacturing, healthcare, energy, business services, technology, materials, and retail) in North America and, to a lesser extent, outside of North America. As of March 31, 2023, the estimated remaining life of the investments that do not allow for redemptions is approximately 66 percent in the next 3 years, 21 percent during the period from 3 to 5 years, 11 percent during the period from 5 to 10 years, and 2 percent during the period from 10 to 15 years. (b)Private Equity - The limited partnerships described in this category employ various strategies generally investing in controlling or minority control equity positions directly in companies and/or assets across various industries (including manufacturing, healthcare, energy, business services, technology, materials, and retail), primarily in private markets within North America and, to a lesser extent, outside of North America. As of March 31, 2023, the estimated remaining life of the investments that do not allow for redemptions is approximately 36 percent in the next 3 years, 17 percent during the period from 3 to 5 years, 40 percent during the period from 5 to 10 years, and 7 percent during the period from 10 to 15 years. (c)Real Assets - The limited partnerships described in this category employ various strategies, which include investing in the equity and/or debt financing of physical assets, including infrastructure (energy, power, water/wastewater, communications), transportation (including airports, ports, toll roads, aircraft, railcars) and real estate in North America, Europe, South America, and Asia. As of March 31, 2023, the estimated remaining life of the investments that do not allow for redemptions is approximately 22 percent in the next 3 years, 36 percent during period from 3 to 5 years, and 42 percent during the period from 5 to 10 years. We record changes in our share of net asset value of the partnerships in net investment income. We receive financial information related to our investments in partnerships and generally record investment income on a one-quarter lag in accordance with our accounting policy.

Realized and unrealized investment gains and losses presented in the preceding tables represent gains and losses only for the time during which the applicable financial instruments were classified as Level 3. The transfers between levels resulted primarily from a change in observability of three inputs used to determine fair values of the securities transferred: (1) transactional data for new issuance and secondary trades, (2) broker/dealer quotes and pricing, primarily related to changes in the level of activity in the market and whether the market was considered orderly, and (3) comparable bond metrics from which to perform an analysis. For fair value measurements of financial instruments that were transferred either into or out of Level 3, we reflect the transfers using the fair value at the beginning of the period. We believe this allows for greater transparency, as all changes in fair value that arise during the reporting period of the transfer are disclosed as a component of our Level 3 reconciliation.
Quantitative Information Regarding Significant Unobservable Inputs | The table below provides quantitative information regarding the significant unobservable inputs used in Level 3 fair value measurements derived from internal models. Unobservable inputs for fixed maturity securities are weighted by the fair value of the securities. Certain securities classified as Level 3 are excluded from the table below due to limitations in our ability to obtain the underlying inputs used by external pricing sources.

All Other Corporate Bonds - Private | $ | 16.8 |  |  | Market Approach |  | Volatility of Credit Market Convention | (a) (b) | 4.62% - 4.62% / 4.62% Priced at Par Value

Embedded Derivative in Modified Coinsurance Arrangement | (13.9) |  |  | Discounted Cash Flows |  | Projected Liability Cash Flows Weighted Spread of Swap Curve | (c) | Actuarial Assumptions 0.6% |
(a)Represents basis point adjustments for credit-specific factors (b)Represents a decision to price based on par value, cost, owner's equity, or the price of the most recent capital funding round when limited data is available (c)Represents various actuarial assumptions required to derive the liability cash flows. Fair value of embedded derivative is most often driven by the change in the weighted average credit spread to the swap curve for the assets backing the hypothetical loan
