ARCC Part I Fees will only be waived to the extent they are paid. The maximum amount of fees that may be waived in a quarter is $10 million, and if ARCC Part I Fees are less than $10 million in any single quarter, the shortfall will not carryover to subsequent quarters.

Performance Income Generally, if at the termination of a fund (and increasingly at interim points in the life of a fund), the fund has not achieved investment returns that (in most cases) exceed the preferred return threshold or (in all cases) the general partner receives net profits over the life of the fund in excess of its allocable share under the applicable partnership agreement, the Company will be obligated to repay carried interest that was received by the Company in excess of the amounts to which the Company is entitled. This contingent obligation is normally reduced by income taxes paid by the Company related to its carried interest. At June 30, 2018 and December 31, 2017, if the Company assumed all existing investments were worthless, the amount of performance income subject to potential repayment, net of tax, which may differ from the recognition of revenue, would have been approximately $472.9 million and $476.1 million, respectively, of which approximately $367.5 million and $370.0 million, respectively, is reimbursable to the Company by certain professionals who are the recipients of such performance income. Management believes the possibility of all of the investments becoming worthless is remote. As of June 30, 2018, if the funds were liquidated at their fair values, there would be $0.2 million of repayment obligations, and accordingly, the Company recorded a contingent repayment liability as June 30, 2018. As of December 31, 2017, if the funds were liquidated at their fair values, there would be no repayment obligation, and accordingly, the Company did not record a contingent repayment liability as of December 31, 2017. Litigation From time to time, the Company is named as a defendant in legal actions relating to transactions conducted in the ordinary course of business. Although there can be no assurance of the outcome of such legal actions, in the opinion of management, the Company does not have a potential liability related to any current legal proceeding or claim that would individually or in the aggregate materially affect its results of operations, financial condition or cash flows.
