Major Revenue-Generating Services and Revenue Recognition The Companys revenues are derived primarily from investment advisory and incentive fees and distribution fees. Investment advisory and incentive fees are directly influenced by the level and mix of assets under management (AUM) as fees are derived from a contractually-determined percentage of AUM for each account as well as incentive fees earned on certain accounts. Advisory fees from the open-end funds, closed-end funds and sub-advisory accounts are computed daily or weekly based on average net assets and amounts receivable are included in investment advisory fees receivable on the consolidated statements of financial condition. Advisory fees from Institutional and Private Wealth Management accounts are generally computed quarterly based on account values as of the end of the preceding quarter, and amounts receivable are included in investment advisory fees receivable on the consolidated statements of financial condition. The Company derived approximately 87%, 85% and 86% of its total revenues from advisory and management fees, including incentive fees, for the periods ended December 31, 2015, 2014 and 2013, respectively. These revenues vary depending upon the level of sales compared with redemptions, financial market conditions, performance and the fee structure for AUM. Revenues derived from the equity-oriented portfolios generally have higher management fee rates than fixed income portfolios. The Company receives incentive fees from certain Institutional and Private Wealth Management accounts, which are based upon meeting or exceeding a specific benchmark index or indices. Incentive fees refer to fees earned when the return generated for the client exceeds the benchmark and can be earned even if the return to the client is negative as long as the return exceeds the benchmark. These fees are recognized, for each respective account, at the end of the stipulated contract period which is either quarterly or annually and varies by account. Receivables du
