Puerto Rico Banking Law Description |  |  |  | The Puerto Rico Banking Law provides that, when the expenditures of a Puerto Rico commercial bank are greater than receipts, the excess of the expenditures over receipts must be charged against the undistributed profits of the bank, and the balance, if any, must be charged against the legal surplus reserve, as a reduction thereof. If the legal surplus reserve is not sufficient to cover such balance in whole or in part, the outstanding amount must be charged against the capital account and the Bank cannot pay dividends until it can replenish the legal surplus reserve to an amount of at least 20% of the original capital contributed. |  |  |  |  |
