Changes in Registrant's Certifying Accountant Effective January 1, 2000, Grant Thornton LLP ("Grant Thornton"), the independent accountants for American Shared Hospital Services (the "Company") sold its Stockton and Sacramento, California offices to Moss Adams LLP, an accounting and consulting firm ("Moss Adams"). Since the individuals performing services for the Company at Grant Thornton are now in the employ of Moss Adams, effective January 14, 2000, the Company dismissed Grant Thornton as its independent accountants and engaged the services of Moss Adams to act as the Company's principal accountants to audit the Company's financial statements. The decision to dismiss Grant Thornton and to retain the services of Moss Adams was approved by the Company's Board of Directors. The reports on the Company's financial statements issued by Grant Thornton and Ernst & Young, the Company's previous accountants, did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles, except the report for the two years ended December 31, 1997 expressed substantial doubt about the Company's ability to continue as a going concern. During the Company's three most recent fiscal years and through January 14, 2000, there have been no disagreements with Grant Thornton or Ernst & Young on any manner of accounting principle or practices, financial statement disclosure, or auditing scope or procedure, which if not resolved to the satisfaction of Grant Thornton or Ernst & Young, would have caused them to make reference thereto in their report on the financial statements for such years. In addition, the Company did not consult Moss Adams regarding the application of accounting principles to a specific contemplated transaction, or any type of audit opinion that might be rendered on the Company's financial statements, or any matter that was the subject of disagreement with the Company's former accountant. The Company has requested that Grant Thornton furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of such letter, dated January 21, 2000 is filed as Exhibit 16.2 to this Form 8-K. The Company previously filed on December 21, 1998 a Report on Form 8-K dated December 14, 1998 regarding the Company's change of independent accountants from Ernst & Young LLP to Grant Thornton LLP.
