[1] U.S. primarily consists of private equity and natural resource and energy related limited partnership investments and public real assets. Non-U.S. primarily consists of annuity contracts and alternative investments.
[2] Cash and Cash Equivalents: Funds generally invested in actively managed collective trust funds or interest bearing accounts.
[3] Debt: The fixed income securities are primarily valued upon a market approach, using matrix pricing and considering a security's relationship to other securities for which quoted prices in an active market may be available, or an income approach, converting future cash flows to a single present value amount. Inputs used in developing fair value estimates include reported trades, broker quotes, benchmark yields, and base spreads.
[4] Investments Measured at Net Asset Value: The underlying debt, public equity, and public real asset investments in this category are generally held in common trust funds, which are either actively or passively managed investment vehicles, that are valued at the net asset value per unit/share multiplied by the number of units/shares held as of the measurement date. The other alternative investments in this category are valued under the practical expedient method which is based on the most recently reported net asset value provided by the management of each private investment fund, adjusted as appropriate, for any lag between the date of the financial reports and the measurement date.
[5] Public Equity - United States: Common stock equity securities which are primarily valued using a market approach based on the quoted market prices.
[6] Other Investments: Primarily consist of insurance contracts which are generally valued using a crediting rate that approximates market returns and investments in underlying securities whose market values are unobservable and determined using pricing models, discounted cash flow methodologies, or similar techniques.
