Determination of the value of a company's stock based on earnings and the market value of assets.
For exchange contracts it is the day on which the two contracting parties exchange the currencies which are being bought or sold. For a spot transaction it is two business banking days forward in the country of the bank providing quotations which determine the spot value date. The only exception to this general rule is the spot day in the quoting centre coinciding with a banking holiday in the country(ies) of the foreign currency(ies). The value date then moves forward a day.
Spot normally settles after two working days.
