Certain mutual funds are valued at the quoted closing price reported on the active market on which the individual securities are traded. Common stock, corporate bonds, and mutual funds that are not traded on an active market are valued at quoted prices reported by investment brokers and dealers based on the underlying terms of the security and comparison to similar securities traded on an active market.Certain mutual funds and other private investments are valued using NAV based on the information provided by the asset fund managers, which reflects the plan’s share of the fair value of the net assets of the investment. Depending on the nature of the assets, the underlying investments are valued using a combination of either discounted cash flows, earnings and market multiples, third party appraisals, or through reference to the quoted market prices of the underlying investments held by the venture, partnership, or private entity where available. In addition, some of these investments have limits on their redemption to monthly, quarterly, semiannually, or annually and may require up to 90 days prior written notice. Valuation adjustments reflect changes in operating results, financial condition, or prospects of the applicable portfolio company.The methods described above may produce a fair value estimate that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe the valuation methods are appropriate and consistent with the methods used by other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.Expected Contributions82
