Under the SDDS, valuation refers to such items as:
1) the exchange rates or conversion factors used to convert foreign-currency-denominated assets and liabilities into the national currency equivalent;
2) whether transactions are recorded at market prices, face or nominal value vs. issue or discounted prices;
3) adjustments to convert CIF imports to an FOB basis;
4) adjustments to align data with balance of payments concepts as well as the frequency of any revaluation (e.g., daily, monthly, quarterly, yearly).
