For instance, if a policy expired on January 1, 2007, the data included on the Experience modification would comprise the period from January 1, 2003 to January 1, 2006. Experience modifiers are normally recalculated for an employer annually. Each year, a newer year's data is added to the three-year window of experience used in the calculation, and the oldest year from the prior calculation is dropped off. The other two years worth of data in the rating window are also updated on an annual basis.
As part of a simualtion I'm running, i need to import a file, simulate the. effects of changes in the file, then output a changed version of the file, for checks on a real machine that takes the file as input.
