Item 4. Changes in Registrant's Certifying Accountant.
On June 18, 1997, the Board of Directors of Helisys, Inc., a Delaware
corporation (the "Company") dismissed Arthur Andersen LLP as the Company's
auditors. On July 10, the Company engaged Deloitte & Touche LLP as its auditors.
In connection with its audit for the fiscal years ended July 31, 1995 and
July 31, 1996, Arthur Andersen LLP advised the Company, including the Company's
Audit Committee of its Board of Directors, that it disagreed with the Company's
recognition of revenue with respect to sales of four rapid prototyping systems
made during each such year. Arthur Andersen LLP advised the Company as to the
requirements for revenue recognition under generally accepted accounting
principles and, consequently, the Company did not reflect such sales in the
audited financial statements for the fiscal years ended July 31, 1995 and July
31, 1996, respectively. If such sales had been reflected on the Company's
financial statements for the fiscal years ended July 31, 1995 and July 31, 1996,
respectively, then Arthur Andersen LLP would have made reference to such matters
in connection with its reports relating to such audited financial statements.
Arthur Andersen LLP's reports on the financial statements for the fiscal years
ending July 31, 1995 and July 31, 1996, respectively, contained no adverse
opinions or disclaimer of opinion, nor were they qualified or modified as to
uncertainty, audit scope or accounting principles.
The Company has authorized Arthur Andersen LLP to respond fully to the
inquiries of Deloitte & Touche LLP concerning the matters set forth above;
however, the Company has not consulted Deloitte & Touche LLP regarding such
matters.
