Business reorganisation deduction apportionment for co operative banks prorates allowable tax deductions between predecessor and successor. Where a co-operative bank undergoes a business reorganisation during a financial year, deductions otherwise allowable under specified income-tax provisions are apportioned between the predecessor and successor by statutory formulas that prorate the deduction by reference to the days each bank held the business in the financial year; transferred undertakings carry forward the applicable allowance provisions to the successor in subsequent years as if the reorganisation had not occurred.
