The following is a discussion of the valuation methodologies used for assets measured at fair value. Sponsored mutual funds and variable insurance funds represent investments in open-end mutual funds and variable insurance funds for which the Company acts as advisor and distributor. The fair value of these securities is determined based on their published net asset values and are categorized as Level 1. Investments of consolidated sponsored investment products represent the underlying debt and equity securities held in sponsored mutual funds in which the Company has an investment and are consolidated by the Company. Equity securities are valued at the official closing price on the exchange on which the securities are traded and are categorized within Level 1. Level 2 investments include certain non-U.S. securities for which closing prices are not readily available or are deemed to not reflect readily available market prices and are valued using an independent pricing service as well as most debt securities which are valued based on quotations received from independent pricing services or from dealers who make markets in such securities. Pricing services do not provide pricing for all securities and therefore indicative bids from dealers are utilized, which are based on pricing models used by market makers in the security and are also included within Level 2. Equity securities include securities traded on active markets and are valued at the official closing price (typically last sale or bid) on the exchange on which the securities are primarily traded and are classified within Level 1. Sponsored closed-end funds represent investments for which the Company acts as advisor and are actively traded on the New York Stock Exchange. The fair value of these securities is determined based on the official closing price and are categorized as Level 1. Nonqualified retirement plan assets represent mutual funds within a nonqualified retirement plan whose fair value is determined based on their published net asset value and are classified as Level 1. Cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities equal or approximate fair value based on the short-term nature of these instruments. The estimated fair value of long-term debt at December 31, 2012, which has a variable interest rate, approximates its carrying value and is classified as Level 2. Marketable securities are reflected in the financial statements at fair value based upon publicly quoted market prices. Transfers into and out of levels are reflected when significant inputs, including market inputs or performance attributes, used for the fair value measurement become observable or unobservable or when the Company determines it has the ability, or no longer has the ability, to redeem, in the near term, certain investments that the Company values using a net asset value, or if the book value of certain equity method investments no longer represents fair value. Securities held by the consolidated sponsored investment products, with an end-of-period value of $5.2 million were transferred from Level 2 to Level 1 during the nine months ended September 30, 2013 due to the availability of unadjusted quoted market prices in active markets. There were no transfers from Level 1 to Level 2 during the nine months ended September 30, 2013. There were no transfers between Level 1 and Level 2 during the nine months ended September 30, 2012.
