         a.   In the case of a failure to file a return or of a fraudulent return, the additional tax may be assessed at any time.
         b.   In the case of a return where a business entity understates net profit, or omits an amount that could properly be included in net profits, or both, which understatement or omission, or both is in excess of twenty-five percent (25%) of the amount of net profit stated in the return, the additional tax may be assessed at any time within six (6) years after the return was filed.
         c.   In the case of an assessment of additional tax relating directly to adjustments  resulting from a final determination of a federal or state audit, the additional tax may be  assessed before the expiration of the times provided in this subsection, or six (6)  months from the date the city receives the final determination of the federal or state audit  from the business entity, whichever is later.
