The Company’s evaluation of available for sale securities in an unrealized loss position includes reviewing credit ratings, assessing the extent of losses, and considering the impact of market conditions for each individual security. For equity securities held at the end of the period, net unrealized gains of $2.6 million and net unrealized losses of $35.9 million were recognized for the three months ended March 31, 2021 and March 31, 2020, respectively. Sponsored Funds The Company has classified its equity investments in the Funds as equity method investments (when the Company owns between 20% and 50% of the fund) or equity securities measured at fair value through net income (when the Company owns less than 20% of the fund). These entities do not meet the criteria of a variable interest entity (“VIE”) and are considered to be voting interest entities (“VOE”). The Company has determined the Funds are VOEs because the structure of the investment products is such that the voting rights held by the equity holders provide for equality among equity investors. Sponsored Privately Offered Funds The Company holds an interest in a privately offered fund structured in the form of a limited liability company. The members of this entity have the substantive ability to remove the Company as managing member or dissolve the entity upon a simple majority vote. This entity does not meet the criteria of a VIE and is considered to be a VOE. Fair Value Accounting standards establish a framework for measuring fair value and a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of the asset. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset. An individual investment’s fair value measurement is assigned a level based upon the observability of the inputs that are significant to the overall valuation. The three-level hierarchy of inputs is summarized as follows: ● Level 1 – Investments are valued using quoted prices in active markets for identical securities. ● Level 2 – Investments are valued using other significant observable inputs, including quoted prices in active markets for similar securities. ● Level 3 – Investments are valued using significant unobservable inputs, including the Company’s own assumptions in determining the fair value of investments. Assets classified as Level 2 can have a variety of observable inputs. These observable inputs are collected and utilized, primarily by an independent pricing service, in different evaluated pricing approaches depending upon the specific asset to determine a value. The carrying amounts of certificates of deposit and commercial paper are measured at amortized cost, which approximates fair value due to the short time between purchase and expected maturity of the investments. Depending on the nature of the inputs, these investments are generally classified as Level 1 or 2 within the fair value hierarchy. U.S. Treasury bills are valued upon quoted market prices for similar assets in active markets, quoted prices for identical or similar assets that are not active and inputs other than quoted prices that are observable or corroborated by observable market data. The fair value of corporate bonds is measured using various techniques, which consider recently executed transactions in securities of the issuer or comparable issuers, market price quotations (where observable), bond spreads and fundamental data relating to the issuer. Term loans are valued using a price or composite price from one or more brokers or dealers as obtained from an independent pricing service. The fair value of loans is estimated using recently executed transactions, market price quotations, credit/market events, and cross-asset pricing. Inputs are generally observable market inputs obtained from independent sources. Term loans are generally categorized in Level 2 of the fair value hierarchy, unless key inputs are unobservable in which case they would be categorized as Level 3. The fair value of equity derivatives is measured based on active market broker quotes, evaluated broker quotes and evaluated prices from vendors. The following tables summarize our investment securities as of March 31, 2021 and December 31, 2020 that are recognized in our consolidated balance sheets using fair value measurements based on the differing levels of inputs.

Cash investments in actively traded money market funds are measured at net asset value and are classified as Level 1. Cash investments in commercial paper are measured at cost, which approximates fair value because of the short time between purchase of the instrument and its expected realization and are classified as Level 2. (2) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been categorized in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the consolidated balance sheets. (3) The Company’s equity method investments are investment companies that record their underlying investments at fair value.
