DELL APPRAISAL RIGHTS MATTER	DELL APPRAISAL RIGHTS MATTER. In 2016, we paid $166.2 million to compensate certain U.S. mutual funds, trusts, separately managed accounts, and subadvised clients (collectively, "Clients") for the denial of their appraisal rights by the Delaware Chancery Court ("Court") in connection with the 2013 leveraged buyout of Dell, Inc. ("Dell"). On December 30, 2016, we entered into a settlement agreement for $100.0 million with our insurance carrier for insurance proceeds related to this matter. We recognized the proceeds as a reduction to the $166.2 million nonrecurring charge that we recognized in 2016 and received the proceeds in January 2017. We received an additional $50 million in insurance proceeds from other insurance carriers in early 2017 and recognized a related reduction in operating expenses. In accordance with the compensation payment, the Clients agreed that in the event the findings made by the Court regarding the fair value of Dell were modified by a final, non-appealable judgment, T. Rowe Price and the Clients would make an appropriate adjustment between themselves, calculated in a manner that is consistent with the methodology used to compensate Clients. We have obtained repayments from Clients because all parties have settled with Dell, and the Court has approved those settlements in final non-appealable judgments. T. Rowe Price retained the first $15.2 million in repayments received in the fourth quarter of 2018 and paid back our insurers the remaining amount received. We recognized $15.2 million as a reduction in operating expenses.

DELL APPRAISAL RIGHTS MATTER.

In 2016, we paid $166.2 million to compensate certain U.S. mutual funds, trusts, separately managed accounts, and subadvised clients (collectively, "Clients") for the denial of their appraisal rights by the Delaware Chancery Court ("Court") in connection with the 2013 leveraged buyout of Dell, Inc. ("Dell").

On December 30, 2016, we entered into a settlement agreement for $100.0 million with our insurance carrier for insurance proceeds related to this matter. We recognized the proceeds as a reduction to the $166.2 million nonrecurring charge that we recognized in 2016 and received the proceeds in January 2017. We received an additional $50 million in insurance proceeds from other insurance carriers in early 2017 and recognized a related reduction in operating expenses.

In accordance with the compensation payment, the Clients agreed that in the event the findings made by the Court regarding the fair value of Dell were modified by a final, non-appealable judgment, T. Rowe Price and the Clients would make an appropriate adjustment between themselves, calculated in a manner that is consistent with the methodology used to compensate Clients. We have obtained repayments from Clients because all parties have settled with Dell, and the Court has approved those settlements in final non-appealable judgments. T. Rowe Price retained the first $15.2 million in repayments received in the fourth quarter of 2018 and paid back our insurers the remaining amount received. We recognized $15.2 million as a reduction in operating expenses.
