Decimals to Come to the Stock Exchange
Decimal pricing will be phased in  in a four step process through April 9, 2001, when all securities on all exchanges will be listed in decimal format.
The rationale behind this change is that investors will benefit from a more exact pricing system that decimals will provide.
SEC Chairman Arthur Levitt said, "Decimal pricing has the potential to significantly benefit investors, and to make our markets more competitive internationally."
