Revenue from Contract with Customer [Abstract]

See Note 2, Significant Accounting Policies, Revenue Recognition, for descriptions of revenues presented in the table below. The adoption of ASC 606 had no significant impact on revenue recognition during 2018, except for the recognition of $12.9 million of performance-based fees in 2018 from a fund in liquidation, which recognition was not probable of significant reversal. Under the previous revenue accounting standard, this performance-based fee would not have been recognized until final liquidation of the fund. Revenues for the years ended December 31, 2018, 2017 and 2016 consisted of the following:
