Item 4.01	Changes in Registrant's Certifying Accountant.
BCTC IV ASSIGNOR CORP. (the "Company") was informed by Reznick Group, P.C. ("Reznick Group"), the Company's independent registered public accounting firm, that it has entered into a business combination with J. H. Cohn, LLP ("J. H. Cohn").  In connection with the business combination J.H. Cohn legally changed its name to CohnReznick LLP ("CohnReznick") and continues to be registered with the PCAOB. On October 29, 2012,
Reznick Group resigned as the Company's independent registered public accounting firm. The Audit Committee of the Company's Board of Directors has approved the appointment of CohnReznick as the Company's independent registered public accounting firm, effective October 29, 2012.
Reznick Group's reports on the Company's financial statements for the fiscal years ended December 31, 2011 and December 31, 2010,
did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.
During the two fiscal years ended December 31, 2011 and December 31, 2010, and the subsequent interim period through October 29, 2012,

During the two fiscal years ended December 31, 2011 and December 31, 2010, and the subsequent interim period through October 29, 2012,
neither the Company, nor anyone acting on its behalf, consulted J.H. Cohn regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered with respect to the financial statements of the Company, and no written report or oral advice was provided to the Company by J.H. Cohn that was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a disagreement (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a "reportable event" (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).
The Company provided Reznick Group with a copy of this Form 8-K and requested that Reznick Group provide the Company with a letter addressed to the Securities and Exchange Commission stating whether or not Reznick Group agrees with the above statements.
