Investment fund loss allocation: non PGBP losses pass to unit holders subject to a minimum twelve month holding requirement. When an investment fund incurs a loss for a previous year (excluding application of clause (23FBA) of section 10), the fund first applies set off; PGBP losses remain with the fund and are carried forward only by the fund, while losses under other heads are passed to unit holders who held units for at least 12 months, who may carry forward and set off those losses; units held for less than twelve months receive no allowance; accumulated non PGBP losses at the fund level as of the cut off date are distributable to unit holders holding units on that date for carry forward by them.
