The following was adapted from a keynote presentation made by Paul Thomas, director of sales and marketing at Wilco International, at the second annual Electronic Trading Forum, Japans T+1 Challenge in Tokyo on March 6. T+1 refers to the proposed change in the settlement period for equities and some fixed income products from three business days after the date of the trade ("trade date + 3" or " T+3") to one business day after the date of the trade.
