The Manual also divides the assets and liabilities into direct investment (investment by 10% and more in non-resident capital); portfolio investment (investment below 10% in the non-resident capital as well as investment in bonds); and other investments (divided into stocks of trade credit, loans, currency and deposits, and any other assets or liabilities). Reserve assets are defined as stocks held by the Monetary Authority to address the imbalances in the balance of payments. The reserve assets are only included as part of assets.
