This press release is amending the record date, ex-date and payable date for the liquidating distribution for BlackRock Defined Opportunity Credit Trust (NYSE:BHL) (the “Fund”) that was previously declared and announced on June 1, 2017. Below are the amended dates for BHL’s liquidating distribution of $3.800000 per share (the “Liquidating Distribution”):

Declaration – 6/1/2017
Record Date – 6/16/2017
Payable Date – 6/28/2017
Ex-Date – 6/29/2017

The amended dates for BHL’s Liquidating Distribution do not impact BHL’s regular monthly distribution that was previously declared and announced on June 1, 2017. As required by the New York Stock Exchange’s Listed Company Manual, BHL’s common stock will trade with “due-bills” representing an assignment of the right to receive the Liquidating Distribution beginning on June 14, 2017 (two business days prior to the record date) through the payable date of June 28, 2017 and will not trade ex-dividend until June 29, 2017, the first business day after the payable date. Stockholders who sell their BHL shares on or before the payable date will not be entitled to receive the Liquidating Distribution.

Due-bills obligate a seller of shares of stock to deliver the dividend payable on such shares to the buyer. The due-bill obligations are settled customarily between the brokers representing the buyers and sellers of the stock. BHL and BlackRock have no obligations for either the amount of the due-bill or the processing of the due-bill. Buyers and sellers of BHL’s common stock should consult their broker before trading in BHL’s common stock to be sure they understand the effect of the NYSE’s due-bill procedures.
