A subject-based addressing scheme comprising a four-part subject code that includes a source field, a class field, a symbol field, and a currency field. The four-part subject code is derived by systematically dividing the perimeters, terms, and conditions of the various derivative instruments into four discreet parts. The source field identifies the source of the information. The class field identifies a principal product class into which the financial instrument falls. The symbol field provides the underlying structure of the derivative instrument, thus, is the principal code used to define each instrument. For each class, an identified list of perimeters are included in the symbol field for defining the derivative instrument. The currency field provides the currency code of the instrument.
