In computing surplus and undivided profits there shall be excluded such surplus as may be required by court order to be set aside and segregated in such manner as not to be available for distribution to stockholders or for investment in properties, the earnings from which are distributable to stockholders; provided further that in computing surplus and undivided profits there shall be included all reserves other than those for definitely fixed liabilities, reasonable depreciation (including in reasonable depreciation, at taxpayer's election, amortization of a war, defense or other emergency facility taken by and allowable to a taxpayer for income tax purposes under R.S. 47:65, provided such amortization is recorded on the books of the taxpayer), bad debts and established valuation reserves, such reserves in all cases to be made under rules and regulations to be prescribed by the collector. When, because of regulations of a governmental agency controlling the books of a taxpayer, the taxpayer is unable to record in its books the full amount of depreciation sustained, the taxpayer may apply to the collector of revenue for permission to add to its reserve for depreciation and deduct from its surplus the amount of depreciation sustained but not recorded, and if the collector finds that the amount proposed to be so added represents a reasonable allowance for actual depreciation, he shall grant such permission.
The collector also shall allow inclusion in depreciation reserves (but shall not limit the reserve thereto, if otherwise reasonable) depreciation taken by and allowable to a taxpayer under R.S. 47:65 provided such depreciation is recorded on the books of the taxpayer.
