In a general sense--not specifically the programs of Finance--if there's a parliamentary authorization, unless it specifically includes the wording that will allow the money to be spent in more than one year, then it lapses on March 31, and the only way that program may be extended is if it returns to Parliament in the supplementary estimates the following year to indicate the money was lapsed and we're spending it again in the following year. That's the only way it can be done for voted items. If it's statutory, then of course it's just a forecast, and it may go on until the end of the program, but for those items that have to be approved by Parliament through the estimates, March 31 is normally the cut-off.
