    The market value of securities and other merchandise under the preceding paragraph shall be calculated based on the paragraph below , provided that for the six business days prior to an ex-rights or ex-dividend date for a TWSE or TPEx listed security pledged as collateral for a margin purchase, with the exception of in cases of a cash capital increase, the market value of the collateral security and the market value of TWSE or TPEx listed securities pledged as collateral shall be calculated based on the respective current day's closing price, minus the value of the cash dividend, or minus the value of the stock dividend calculated based on the current day's closing price.

2. TWSE or TPEx listed securities: the closing price of Taiwan Stock Exchange or Taipei Exchange.

    The securities firm may not use the newly issued rights shares or the stock of the assignee company of the demerger under the preceding paragraph as a source of securities for lending in its conduct of securities trading short sale operations or as collateral for refinancing.
    The provisions of paragraph 2 shall not apply to newly issued rights shares or the stock of the assignee company of the demerger used as collateral. After the security is traded ex-rights, the market value of the newly issued rights shares shall be calculated as 70 percent of the closing price if they are TWSE or TPEx listed securities for margin purchase and short sale, or 50 percent of the closing price if they are not qualified according to Article 2 or 3 of the Standards Governing Eligibility of Securities for Margin Purchase and Short Sale, or are suspended according to Article 4 or 5 of the same Standards.

Article 54
    Where the overall collateral maintenance ratio of the customer margin account is lower than 130 percent, the securities firm shall issue a margin call to the customer demanding the deposit, within two business days from the day the margin call is received, of additional margin collateral for the margin purchase or short sale that falls below the collateral maintenance ratio, to cover the margin deficiency.
    Margin deficiencies that a customer is required to cover under the preceding paragraph shall be calculated by the following formulas:
■ deficiency in margin for margin purchase = original margin purchase amount - (closing price on the day of calculation × number of shares purchased on margin × margin purchase leverage ratio) - (par value, closing price and average closing price of the day of calculation or net asset value per beneficiary unit of the prior business day × unit number of shares of the stock under paragraph 3 and securities deposited as collateral or other merchandise under Article 57 × margin purchase leverage ratio)
■ deficiency in margin for short sale = (closing price on the day of calculation × number of shares sold short × margin percentage required for short sale - initial margin for short sale) + (closing price on the day of calculation × number of shares sold short - original short sale proceeds) - (par value, closing price and average closing price of the day of calculation or net asset value per beneficiary unit of the prior business day × unit number of shares of the securities deposited as collateral under Article 57 or other merchandise).
    In the formula for calculating the deficiency for margin purchase under the preceding paragraph, if the stock under paragraph 3 of the preceding article or the securities deposited as collateral or other merchandise under Article 57 are categorized as book-entry central government bonds, local government bonds, corporate bonds, financial bonds, gold that is registered for trading over the counter, an open-end type securities investment trust fund beneficiary certificate and futures trust fund beneficiary certificate, its financing ratio shall be calculated based on the maximum financing ratio of TWSE or TPEx listings announced by the competent authority; for others that are not eligible for margin purchase or short sale under Article 2 or 3 of the Standards Governing Eligibility of Securities for Margin Purchase and Short Sale or are temporarily suspended under Article 4 or 5 of the same Standards, then the margin purchase leverage ratio shall be set at zero.
    Where trading of securities has been suspended or halted, the collateral maintenance ratio in paragraph 1 of the preceding article and the margin deficiencies required to cover in paragraph 2 of this article shall be calculated based on the closing price of the business day immediately before suspension or halting of trading.
    For purposes of calculation of the collateral maintenance ratio in the preceding article and the margin deficiencies that a customer is required to cover in paragraph 2 of this article, if a closing price is not available for the given day, it shall be calculated as the price determined by the following principles:

1. When the highest buy price quoted as of market close on the given day is higher than the auction reference price at market opening on the TWSE or the basis price for the opening of trading on the TPEx, the highest buy price quoted will be the price.
2. When the lowest sell price quoted as of market close on the given day is lower than the auction reference price at market opening on the TWSE or the basis price for the opening of trading on the TPEx, the lowest sell price quoted will be the price.
3. When the above circumstances are not met, the auction reference price at market opening on the TWSE or the basis price for the opening of trading on the TPEx will be the price.

    The terms "the auction reference price at market opening" and "the basis price for the opening of trading" in the preceding paragraph shall have the meaning specified in Article 58-3, paragraph 4 of the TWSE Operating Rules, or Article 60-1 of the TPEx Trading Rules.

1. If the overall collateral maintenance ratio of the customer's margin account still falls below the required level on the given day, the securities firm shall dispose of the collateral by the mutatis mutandis application of Article 81, paragraph 3, starting from the next business day.
2. If the overall collateral maintenance ratio of the customer's margin account is restored to 130 percent or higher on the given day, the securities firm may refrain for the time being from disposing of the collateral; provided that if the ratio again falls below the required level on any subsequent business day, and if the customer fails to make additional deposit on its own initiative to cover the deficiency that same afternoon, it shall dispose of the collateral by the mutatis mutandis application of Article 81, paragraph 3, starting from the next business day.
3. If prior to disposal of collateral pursuant to the provisions of the preceding subparagraph, the customer makes successive deposits sufficient to cover the deficiency stated in the margin call, the securities firm shall expunge the record of the margin call.
4. If the overall collateral maintenance ratio of the customer's margin account is restored to 166 percent or higher, the securities firm shall expunge the record of the margin call.

    The collateral disposed of under the preceding paragraph shall be the collateral for a given margin purchase or short sale in the customer's margin account for which a margin call has been issued demanding additional deposit of collateral to meet the collateral maintenance ratio. Any surplus amount after the disposal shall be returned. If the disposal proceeds are insufficient to satisfy the obligation, or if, for said collateral for margin purchases and/or short sales that is disposed of, brokerage trading orders have been placed at auction reference price at market opening of the current trading session or at basis price for the opening of trading, ± 10 percent, before market opening for six consecutive days (brokerage trading orders may be placed at market price instead during intraday trading hours other than a given period before market opening and after close of market), and the trades thus cannot be fully executed, the deficiency shall be offset by other funds in the margin account. If there is still a deficiency remaining after such offsetting, the securities firm shall request the customer to make up the remaining deficiency on the next business day.
    When a securities firm disposes of the collateral for margin purchases and/or short sales in customer margin accounts where a margin call has been issued demanding additional deposit of collateral to meet the collateral maintenance ratio, and where the customers concerned have failed to make the additional deposit within the specified time limit, the securities firm may take the newly issued rights shares or the stock of the assignee company of the demerger of those customers that are in amounts of less than one trading unit and combine them into trading units for the purpose of disposal.
