Explanation of Responses:
(1)	The dividend equivalent rights accrued on nine restricted stock unit grants of which the reporting person has elected to defer receipt of the shares underlying the RSUs. Each RSU and DER represent a contingent right to receive one share of BWXT common stock. In accordance with the deferral election, the DERs will be delivered to the reporting person proportionately with the RSUs to which they relate.
(2)	The dividend equivalent rights accrued on the restricted stock unit grants of which the reporting person deferred receipt of the shares underlying the RSU. Each DER represents a contingent right to receive one share of BWXT common stock. Since the reporting person's deferral election to receive shares on December 1, 2021 occurred between the company's fourth quarter 2021 dividend record and payment dates, the DERs for this dividend payment were delivered to the reporting person on December 10, 2021, the dividend payment date.
