ITEM 4. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT.
On May 23, 2002, the board of directors of DIANON Systems, Inc. (the
"Company"), upon recommendation of its Audit Committee, dismissed Arthur
Andersen LLP ("Arthur Andersen") as the Company's independent public accountants
and engaged Ernst & Young ("E&Y") to serve as the Company's independent public
accountants for the fiscal year ending December 31, 2002.
None of Arthur Andersen's reports on the Company's consolidated
financial statements for the fiscal years ended December 31, 2001 and December
31, 2000 contained an adverse opinion or disclaimer of opinion, nor was any such
report qualified or modified as to uncertainty, audit scope or accounting
principles.
During the Company's two most recent fiscal years ended December 31,
2001 and 2000, and the subsequent interim period through May 23, 2002, there
were no disagreements between the Company and Arthur Andersen on any matters of
accounting principles or practices, financial statement disclosure, or auditing
scope or procedure, which disagreements, if not resolved to Arthur Andersen's
satisfaction, would have caused Arthur Andersen to make reference to the subject
matter of the disagreement in connection with its reports. None of the
reportable events described under Item 304(a)(1)(v) of Regulation S-K occurred
within the two most recent fiscal years ended December 31, 2001, or within the
interim period through the date of this report.
During the Company's two most recent fiscal years and through the
date of this Form 8-K, the Company did not consult E&Y with respect to the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Company's consolidated financial statements, or any other matters or
reportable events listed in Items 304(a)(2)(i) and (ii) of Regulation S-K.
The Company provided Arthur Andersen with a copy of the foregoing
disclosures. Attached as Exhibit 16.1 is a copy of Arthur Andersen's letter,
dated May 23, 2002, evidencing its agreement with the statements set forth in
this report.
