We have been furnished with a copy of the response to Item 4.01 of Form 8-K for the event that occurred on March 11, 2020, to be filed by our former client, Hallmark Financial Services, Inc. (the “Company”). We agree with the statements made in response to that Item insofar as they relate to our Firm. In addition, with respect to the matters of disagreement, BDO expanded significantly the scope of its audit on January 31, 2020, with respect to which a substantial portion of the requests had not been received and/or tested prior to our termination.

Very Truly Yours,
