SPAN system is used to evaluate possible losses in all positions of a trader in the derivatives market (the so-called “portfolio approach”) and calculate the initial margin requirement. Besides, SPAN enables to determine the size of the guarantee fund, which is necessary to cover risks of operations in derivatives not covered by the initial margin.
According to the MICEX President Alexander Potemkin, this methodology will be the main part of the modernized system of risk management in the derivatives market, which is now being developed by the MICEX and which will meet world standards. The modernized system of risk management is to be launched in the first half of 2006. Later, this methodology may be used in other markets of the MICEX Group in the framework of the National Clearing Center.

SPAN (Standard Portfolio Analysis of Risk) was developed by CME in 1988. This system analyses the risks of a portfolio which may include derivatives (futures and options) and underlying assets. SPAN takes into account the functional and statistical relationships between different components of a portfolio and implements the so-called portfolio approach to risk evaluation, which enables to make well-grounded calculation of the initial margin.
