Current market value
Current market value of: (1) A security means: (i) Throughout the day of the purchase or sale of a security, the security's total cost of purchase or the net proceeds of its sale including any commissions charged; or (ii) At any other time, the closing sale price of the security on the preceding business day, as shown by any regularly published reporting or quotation service. If there is no closing sale price, the creditor may use any reasonable estimate of the market value of the security as of the close of business on the preceding business day. (2) Any other collateral means a value determined by any reasonable method.
