The financing limit of the account will be automatically evaluated based on the cash you deposit or the transfer situation. If you need to adjust, please login to the Longbridge App \> *Assets* \> *Financing Status* for application, or contact your account manager. ## 1\. Margin - **Initial margin (IM):** The margin required to be deposited when opening a position - **Maintenance margin (MM):** The level of equity assets to be maintained - **Freed-up margin (FM):** When equity assets fall below this level, positions may be forced to liquidate immediately - **IM/MM/FM requirement** = Sum (Market value of individual investment products × Corresponding margin factor) ## 2\. Margin Requirements **Equity assets** = Cash balance (ledger) + Total portfolio market value **Available funds** - **Available funds (including financing)** = Equity assets - Initial margin requirements - Suspended funds - **Maximum buying power** = Available funds / Initial margin (IM) The balance owed shall not exceed the financing limit. **Example:** You deposited USD 10,000 in cash and purchased shares with an initial margin factor (IM ratio) of 30%, and the account financing limit is USD 20,000 Maximum buying power = USD 10,000 / 30% = USD 33,333 Assuming that the account financing limit is USD 20,000, the account can only actually purchase a maximum of USD 30,000 of the stock (USD 10,000 in cash and USD 20,000 in financing). **Margin call** The margin call will be higher than the difference between the maintenance margin and equity assets. When equity assets fall below the maintenance level, the company will issue a margin call. You shall pay the margin call difference within 3 trading days of receiving the notice (including the day of receipt of the notice). **Example: margin call case** You deposited USD 10,000 in cash and USD 5,000 worth of Class A shares (IM: 30%, MM: 25%) and purchased USD 25,000 worth of Class B shares (IM: 50%, MM: 45%). Assume that the market value of B stock falls to USD 19,500. After you purchased the stock, and after the market value of B stock fell, your hold position was as follows. Cash balance HKD 15,000 Initial margin for holdings HKD 11,250 (HKD 5,000 × 30% + HKD 19,500 × 50%) Maintenance margin for holdings HKD 10,025 (HKD 5,000 × 25% + HKD 19,500 × 45%) Equity Assets HKD 9,500 Margin Call HKD 1,750 You are required to bring the equity assets in his account up to margin requirements on or before a specified date. If you choose to sell securities, the market value required to be sold shall not exceed the difference between the initial margin and equity assets / initial margin ratio (IM ratio). **When the equity assets are lower than the forced liquidation margin, the difference in the margin call shall be paid off immediately, otherwise the position may be forced to liquidate immediately.** The actual amount of margin call may be higher, depending on the nature of the stock and company policies. ## 3\. **Balance fund management service** You can choose to join the Cash Plus management service, which is an idle fund financial product launched by Long Bridge HK Limited. It provides cash value-added services, meeting your needs for stock purchasing at any time while generating returns on idle funds.
