Article 2    A securities firm conducting margin purchase and short sale operations in securities trading shall do so in accordance with securities trading laws and regulations, these Rules, as well as other relevant bylaws, rules, public announcements, and circular letters of the Taiwan Stock Exchange Corporation (TWSE), Taipei Exchange (TPEx), and central securities depositories.
Article 3    A securities firm applying for conducting margin purchase and short sale operations in securities trading shall fill out an application form and submit relevant documentation to the TWSE. The TWSE will forward the application to the competent authority for approval upon verifying that all qualification requirements and applicable provisions of these Rules are conformed to.
    Upon approval by the competent authority to conduct securities trading margin purchase and short sale business, a securities firm shall submit the following documents by letter to the TWSE for recordation two days before commencing such business:
  1. A photocopy of the permit from the competent authority.
  2. A description of the system of internal controls over securities trading margin purchase and short sale operations.
  3. A roster of the responsible and associated persons of the department in charge of these operations and documents certifying their qualifications.
    The responsible and associated persons under the third subparagraph of the preceding paragraph shall be registered with the TWSE before they may engage in such business. Any change of personnel in such positions shall be registered within five days.
    A securities firm which has been approved by the competent authority to conduct securities trading margin purchase and short sale business shall cease to engage in such business if its capital adequacy ratio is lower than 150% for 2 continuous months. However, repayment and satisfaction is not included. Until 3 months of continuous compliance and obtain the competent authority's further approval, a securities firm may re-open its business; for securities firms which have obtained the approval but yet to commence its business, the aforesaid rules shall also apply.
Article 4    A securities firm shall confine its securities trading margin purchase and short sale operations for TWSE- or TPEx-listed securities to those funds and securities that are deliverable after execution of customer orders for normal-settlement brokerage trades on the automated trade matching system of the TWSE centralized securities exchange market or TPEx, for which the underlying securities are those publicly announced by the TWSE or TPEx as eligible for margin purchases and short sales.
    None of odd-lot or block trades or the trades specified in Article 74 of the Operating Rules of the Taiwan Stock Exchange Corporation (hereinafter, "TWSE Operating Rules") or Article 39 of the Taipei Exchange Rules Governing the Review of Securities for Trading on the TPEx (hereinafter, the "TPEx Trading Rules") are eligible for margin purchases or short sales.
Article 5    A securities firm conducting securities trading margin purchase and short sale operations shall be subject to the requirements of the competent authority in relation to amount limit, duration, margin purchase leverage ratio, and short sale margin.
    The duration of a securities trading margin purchase and short sale is six months. A customer may apply for extension prior to the expiration of the duration. The number of such applications allowed is two. A securities firm shall review a customer's credit status before granting an extension.
    Upon accepting an application for the opening of a margin account, a securities firm shall sign application documentation for extending the duration of each margin purchase and short sale on a blanket basis with the customer. The application documentation must include the number of extensions available for selection and the follow-up to the evaluation result regarding applications for extension upon expiration. Upon execution, the said documentation shall apply to each subsequent margin purchase and short sale. Where a customer seeks to amend the number of extensions, it shall re-sign the application documentation.

    Where a securities firm disagrees with an extension sought by a customer as in the preceding paragraph, or a margin purchase and short sale has been extended twice, said firm shall notify the customer in writing ten business days prior to the expiry.
    The duration of a margin purchase and short sale where the underlying securities are subject to a suspension of trading or transaction is extended until the resumption of their trading or transaction.
    The securities firm shall give a written notice to the customer of a margin purchase or short sale no later than 10 business days before the end of the duration as fixed by the competent authority under the preceding paragraph. Notwithstanding the foregoing, the notice is not required if, pursuant to the Operational Guidelines Governing Securities Firms and Securities Finance Enterprises Accepting Applications by Customers for Extending the Duration of Each Margin Purchase and Short Sale the customer has entered into application documentation for extending the duration of each margin purchase and short sale on a blanket basis and the securities firm has granted consent to the customer for such extension.

    Before providing securities borrowed through the TWSE securities lending system, securities borrowed from customers in money lending conducted in connection with securities business, securities borrowed from securities firms or securities finance enterprises conducting money lending in connection with securities business or conducting margin purchases and short sales of securities (“Borrowed Securities”), or its proprietary shares of securities (“Proprietary Securities”), to a customer for short selling, a securities firm shall determine the rate, calculation, and method of collection of the short sale fee with the customer, where the interest rate shall be below 20% per annum.
    Upon adjustment to any interest rates or fee rates described in the preceding two paragraphs, the adjusted interest or fee rates shall apply to any and all open positions in margin purchases and short sales as from the date of the adjustment.
    The payment and receipt of interests and fees are determined by the securities firm where the extension in paragraph 6 of the preceding article exceeds the duration of the margin purchase and short sale.
    A securities firm shall charge a short sale handling fee from customers for providing securities acquired through margin purchases to them for short selling, and shall charge a short sale fee from customers for providing Borrowed Securities or Proprietary Securities to them for short selling.

Article 48    For executed margin purchases and short sales, a securities firm shall calculate the balance of long and short positions in a customer's margin account after close of market each day. The customer shall settle with cash or spot securities any portion that is beyond the long position limit or short position limit.
    After a customer places an order for a short sale, if a rise in the price causes the customer's short balance to exceed the short position limit, the securities firm may lend the security to the customer for short selling within the extent of the daily price limit on the given day, provided that if short sales of ETF beneficial certificates with foreign component securities, offshore ETF beneficial certificates, or futures ETF beneficial certificates are not subject to a price limit, the securities firm may accommodate short sale of the securities within the extent of the highest trade price on the given day.
    When the market price per trading unit of a security sold short exceeds the short position limit, a customer may sell one trading unit short if the customer's margin account is clear of any short balance.
Article 49    Upon execution of a margin purchase or short sale, the securities firm shall, by 10 a.m. on the second business day after the trade date, collect from the customer a margin for the margin purchase, based on the balance of the trade price of the margin purchase less the dollar amount of the margin loan, or in the case of a short sale, a margin for the short sale, based on the trade price of the short sale multiplied by a required percentage (any amount less than NT$100 shall be calculated as NT$100).
Article 50    A securities firm providing a margin loan to a customer shall do so and perform settlement on behalf of the customer based on the amount of the margin loan as calculated by multiplying the trade price of the margin purchase by a required percentage (with any amount less than NT$1,000 excluded from calculation); all securities bought on margin shall serve as collateral.
    A securities firm lending a security to a customer for short selling shall do so and perform settlement on behalf of the customer based on the type and quantity of the security sold short in that trade; the proceeds from the short sale conducted by the customer with securities provided by the securities firm acquired through margin purchase shall serve as collateral after deducting the securities transaction tax, the short sale handling fee, and the securities firm handling fee; proceeds from the short sale conducted by the customer with Borrowed Securities or Proprietary Securities shall serve as collateral after deducting the securities transaction tax and securities firm handling fee.
    A securities firm borrowing securities from a securities firm or securities finance enterprise conducting money lending in connection with securities business shall deposit a performance bond with the TWSE in accordance with the Regulations Governing the Performance Bond for the Lending of Securities by Securities Firms and Securities Finance Enterprises.
Article 51    A securities firm shall, for a margin purchase, collect from the customer the interest on the margin loan at the stated interest rate, and, for a short sale, pay interest at the stated interest rate on the short sale margin and on the remainder of the proceeds from the short sale under paragraph 2 of the preceding article.
    The interest under the preceding paragraph shall accrue for the number of days from the second business day after the day on which the margin purchase or short sale is executed to the day before the payment day.
Article 52    Where a securities firm charges a customer a short sale fee, expenses incurred from refinancing from a securities finance enterprise due to a shortfall in the security shall be borne by the securities firm.
    Where a securities firm charges a customer a short sale handling fee, the various fees and expenses required for any competitive bid loan, negotiated transaction, or purchase by tender offer conducted by a securities finance enterprise shall be borne by the customer. The securities firm shall further calculate pursuant to the following principles for short sellers the fees and expenses for each share of the security sold short based on the short balance for that security for which a short sale handling fee is charged, on the date the shortfall in the security occurs, and then collect payment from each short seller in the short sales in an amount determined by the number of shares it sells short:
  1. If the margin balance is larger than or equal to the short balance of the security for which a short sale handling fee is charged, and the balance of Borrowed Securities and Proprietary Securities is smaller than the balance of securities lent through securities lending, securities lent to securities firms and securities finance enterprises conducting money lending in connection with securities business, and securities lent through the TWSE securities lending system ("Lending Balance") plus the short balance for which a short sale fee is charged, the short seller does not have to bear the fees.
  2. If the margin balance is smaller than the short balance for which a short sale handling fee is charged, and the balance of Borrowed Securities and Proprietary Securities is larger than or equal to the Lending Balance plus the short balance for which a short sale fee is charged, the short seller shall bear the fees in full.
  3. If the margin balance is smaller than the short balance for which a short sale handling fee is charged, and the balance of Borrowed Securities and Proprietary Securities is smaller than the Lending Balance plus the short balance for which a short sale fee is charged, the short seller shall bear a proportion of the fees as calculated pursuant to the following formula:
    (short balance for which a short sale handling fee is charged - margin balance)/[(short balance for which a short sale handling fee is charged - margin balance) + (Lending Balance + short balance for which a short sale fee is charged) – (balance of Borrowed Securities and Proprietary Securities)]
    The securities firm may collect the fees and expenses receivable under the preceding paragraph by deducting the amount from the short sale collateral funds in the customer's margin account.
    During the suspension or halting of trading of the securities, if there is a difference in the number of the securities, the securities firm may borrow from the securities finance company. The securities finance company may purchase securities by tender offer according to Chapter 3 of the TWSE Rules Governing Purchase of Listed Securities by Reverse Auction or according to Chapter 3 of the TPEx Rules Governing Reverse Auction of TPEx Listed Securities in the event of inadequate sources of securities.
    For shares of securities obtained and distributable as a result of a securities finance enterprises conducting a purchase by tender offer, the securities firm shall distribute the shares to those short sellers who have a short balance for which a short sale handling fee is charged in the security, on the date the security falls short, in a quantity decided on a pro rata basis in accordance with the principles of paragraph 2 and rounded to an integral trading unit, for them to buy in to cover their short positions; any quantity remaining after the distribution shall further be distributed to these short sellers in the order of the size of the decimal portion of their respective distributable quantity, and if for a decimal number there are multiple short sellers, to one or more of them determined by drawing lots.
    Where two or more tender offer purchases are conducted [to cover securities shortfalls arising in the course of short sale operations], the dollar amounts of the purchases that are allocable to the short sellers shall be calculated by the weighted average method.
Article 53     A securities firm shall calculate, on a daily mark-to-market basis, the collateral maintenance ratio for each margin account as a whole and for each margin purchase and short sale in each margin account by the following formula:
collateral maintenance ratio = {market value of collateral securities for margin purchase(s) + initial collateral and short margin for short sale(s) + market value of securities deposited as collateral or other merchandise} ÷ {original margin purchase amount(s) + market value of underlying securities sold short} × 100 percent
    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.
  1. TWSE or TPEx listed book-entry central government bonds, local government bonds, corporate bonds, financial bonds: par value.
  2. TWSE or TPEx listed securities: the closing price of Taiwan Stock Exchange or Taipei Exchange.
  3. Gold that is registered for trading over the counter: the average price at closing based on the highest buying price quote and the lowest selling price quote ("the average closing price").
  4. An open-end type securities investment trust fund beneficiary certificate and futures trust fund beneficiary certificate: the net asset value per beneficiary unit of the prior business day.
    If the security the customer purchases on margin is subject to a 20 percent or more share dividend rate in gratuitous distribution of shares, or the issuer of the securities conducts a demerger and capital reduction, and after the capital reduction, the stock resumes trading and is TWSE or TPEx listed on the same day as the stock of the assignee company of the demerger, then unless the competent authority has otherwise imposed trading restrictions on the security, the newly issued rights shares or the stock of the assignee company of the demerger shall all be pledged as collateral, with the option of income tax deferral to be waived, and shall be transferred through book-entry by the central securities depository into the securities firm's segregated account for margin purchases and short sales, notwithstanding the provisions of Article 33 of the Regulations Governing Handling of Shareholder Services by Public Companies.
    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. After such shares have been transferred into the securities firm's segregated account for margin purchases and short sales, their market value is no longer required to be discounted.
    The market value of collateral securities for margin purchases and the original collateral and short margin for short sales, the market value of securities deposited as collateral or other merchandise referred to in paragraph 1 means the balance of the money, market value of securities and other merchandise in a customer margin account after deducting the short sale fee, competitive auction lending fee, negotiated lending fee, and fee for purchase of securities by tender offer [to meet a securities shortfall in short selling]; if there is any residual obligation after a settlement trade has been made or after the securities firm has disposed of the collateral, the residual obligation shall also be deducted.
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.
Article 56    If a deficiency occurs with respect to the overall collateral maintenance ratio of a customer's margin account as a result of settlement of any part of the transaction of margin purchase and short sale, the securities firm shall retain as collateral all or part of the funds and/or securities payable within the extent necessary to maintain the 130 percent collateral maintenance ratio.

Article 78    When the TWSE or TPEx has ratified and publicly announced the delisting from the stock exchange or termination of TPEx trading of a collateral eligible for margin purchase and short sale transactions, a securities firm shall request customers to cover and close out any margin purchases or short sales of such collateral by repaying the margin loans or returning the borrowed securities by the tenth business day before the delisting or the termination of TPEx trading. If a customer fails to cover and close out any margin purchase or short sale by repaying the margin loan or returning the borrowed security within the deadline, unless agreed by both parties otherwise, the securities firm shall dispose of said collateral on the following business day. 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; or if the collateral cannot be disposed of on account of a suspension of trading under Article 50 or 50-3 of the Operating Rules of the TWSE or Article 12-1 of the TPEx Rules Governing Securities Trading on the TPEx; or if, after reverse auction is conducted in respect of the collateral in accordance with Article 81, paragraph 5, the proceeds do not sufficiently cover the obligation, then 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. However, these provisions shall not apply under any of the following circumstances:
  1. The issuing company has applied for conversion of its TPEx listed securities to TWSE listed securities.
  2. The securities of a TWSE or TPEx listed company are delisted due to the company's merger, and the surviving company uses the securities which are eligible for margin purchase and short sale transactions for payment of all or part of the consideration to shareholders of the non-surviving company.
  3. The securities of a TWSE or TPEx listed company are delisted due to a share conversion, and the shares after conversion are still eligible for margin purchase and short sale transactions.
    or where securities of both the surviving and non-surviving TWSE or TPEx listed companies in a merger are eligible for margin purchase and short sale transactions.
    After termination of the contract for trading of Over-the-Counter (OTC) securities eligible for margin purchase and short sale to be converted as TWSE listed securities, the customer shall proceed to settlement of the balance of its existing margin purchases and short sales within the time limits for margin purchase and short sale. If prior to listing of these securities to be eligible for margin purchase and short sale, the customer acquired these securities through margin purchase or short sale, redemption shall be made by cash or by delivery of spot securities, respectively.
Article 79    On the business day preceding book closure of an issuing company or the interest payment date of open-end fund beneficiary certificates, a securities firm shall prepare a share transfer list with respect to the security of the issuing company held in customer margin accounts, specifying those shares that are purchased on margin and those that are deposited as collateral to offset against margin collateral requirements, and send the share transfer and interest claim list, together with the data file, to the central securities depository to carry out share transfer procedures with the issuing company or its shareholder services agent on behalf of the customers. Provided, where the issuing company closes its books because of a special shareholders meeting, the number of shares of the issuing company's stock held in customer margin accounts that are purchased on margin shall, for the purposes of share transfers, be calculated by the securities firm in accordance with the provisions of the Rules Governing the Calculation of Number of Shares of Margin Buyers for the Purposes of Share Transfers Upon Special Shareholders Meetings.
    A customer using book-entry central government bonds to settle a margin sale may engage a securities firm to collect interest payment via the Book-Entry Central Government Securities Clearing Bank, and transfer the interest payment less any withholding tax deducted as agreed by both parties back to the customer prior to the business day following the interest payment date.

   Chapter VIII Risk Control
Article 85    When a securities firm deals with margin purchases and short sales, the total amount of margin purchases or short sales of securities provided to its customers, plus securities lent to the securities firms or securities finance enterprise engaging in borrowing of securities, or securities lent at the TWSE securities lending system, or securities lent for lending auction or lending negotiation ("Lent Securities") may not exceed 250% of its worth, respectively.
    Where a securities firm maintains a regulatory capital adequacy ratio of 250% or above for three consecutive months, the total amount of margin purchases or short sales of securities which it conducts from and to customers, plus the Lent Securities, may not exceed 400% of its net worth, respectively.
    Where, after the preceding paragraph is complied with, a securities firm maintains a regulatory capital adequacy ratio lower than 250% for two consecutive months and the total amount of its margin purchases from or short sales to customers, plus the Lent Securities, exceeds 250% of its net worth, it shall cease to conduct margin purchases from, short sales to or lending securities to customers. When such total amount falls below 250% of its net worth or its regulatory capital adequacy ratio remains 250% or above for three consecutive months, the preceding two paragraphs will apply, respectively.
    When a securities firm conducts margin purchases and short sales of securities, the sum of the total amount of its margin purchases from customers plus the total financing amount of money lent in connection with securities business may not exceed 400% of its net worth; the sum of the total amount of short sales to customers plus the total dollar amount of securities lent in connection with borrowing of securities business may not exceed 400% of its net worth.
Article 86    When a securities firm conducts margin purchases and short sales of securities, the total amount of its margin purchases of each security may not exceed 10% of its net worth.

Article 87    The net worth of a financial institution operating as a securities firm concurrently is calculated based on the exclusively appropriated working capital, provided it may not exceed the maximum net worth of the securities firm in the same period as specified in the preceding two articles and the limit prescribed by the competent authority.
Article 88    When conducting margin purchases and short sales of securities, a securities firm shall implement an internal control over the amount limit for margin purchase and short sale applicable to its customers and establish the operating procedures for management of amount limit for margin purchase and short sale applicable to its customers, which shall cover, to a minimum extent, the following:
  1. Method of assessment of a customer's maximum amount for margin purchase and short sale. The amount approved to the customer for other loan business should also be taken into consideration in the assessment. There should be requirements that establish the sum of funds or securities financed to a single customer in the overall loan business should not exceed a certain percentage of its net worth. If the amount of margin purchases or short sales conducted by a single customer exceeds NT$300 million or 1 percent of the securities firm's net worth, whichever is higher, a proposal shall be submitted to the board of directors for approval.
  2. Method of assessment of a customer's maximum amount for margin purchase and short sale of individual securities. The amount approved to the customer for other loan business should also be taken into consideration in the assessment.
  3. Method of identifying high risk securities or high risk customers. Establishment of special procedure for supervision and approval/determination of the amount limit for margin purchase and short sale applicable to high risk securities or high risk customers.
  4. Method to determine the amount limit for sources of securities available for a customer's short sales based on a fair and reasonable principle and to avoid circumstances where the same customer acquires most securities from the sources. Special care is required in the case of securities for which the TWSE or the TPEx allocates the amount limit.
Article 89    In assessing a customer's maximum amount for margin purchase and short sale, if the securities firm is fully aware that or reasonably determines certain customers are related to each other, i.e. they are related in terms of credit risks (e.g. acting as trading agent on another's behalf), it should control and manage the amount limit for margin purchase and short sale and the amounts of other loan business available to these customers.
    Control and management of loan amount limit for customers related to each other as described in the preceding paragraph apply to a customer's opening of a new account, contract renewal and changes to amount limit, as well as changes to amount limit for another customer related to the customer or addition of a customer related to the customer.
