Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure	Commitments and ContingenciesFrom time to time, the Company is involved in legal matters relating to claims arising in the ordinary course of business. There are currently no such matters pending that the Company believes could have a material adverse effect on its consolidated results of operations, cash flows or financial position.The Company periodically commits to fund a portion of the equity in certain of its sponsored investment products. The Company has committed to co-invest up to $5,100,000 alongside GRP-TE, a portion of which is made through GRP-TE and the remainder of which is made through GRP-CIP for up to 12 years through the life of GRP-TE. As of December 31, 2020, the Company had funded approximately $3,800,000 with respect to this commitment. The actual timing for funding the unfunded portion of this commitment is currently unknown, as the drawdown of the Company’s unfunded commitment is contingent on the timing of drawdowns by the underlying funds in which GRP-TE and GRP-CIP invest. The unfunded commitment is not recorded on the Company’s consolidated statements of financial condition.
