Carried interest income earned not yet received as of the balance sheet date and due to the general partner or investment manager varies depending on the terms of the applicable fund agreements. Generally, carried interest with respect to the private equity funds is payable and is distributed to the fund's general partner upon realization of an investment if the fund's cumulative returns are in excess of the preferred return. For most capital markets funds, carried interest is payable in certain cases based on realizations or after the end of the relevant fund's fiscal year or fiscal quarter, subject to high watermark provisions.
