It looks like you are trying to convert the FinPeriod ID to the Start Date of that Fin Period.
Now the approach you take may be fine in case when the Fin Periods are matching the Calendar month, but otherwise this may cause an issue.
I would recommend instead of doing this, simply join the MasterFinPeriod table on FinPeriodID and then use the StartDate.
That should solve your problem and also account for the actual start date.
