Matters not provided herein shall be subject to generally accepted auditing standards ("the Auditing Standards") issued by the Accounting Research and Development Foundation.

However, if the stock of a company has no par value or a par value other than NT$10, the aforesaid calculation of 40 percent of paid-in capital shall be replaced by 20 percent of the equity attributable to owners of the parent.
