Items relating to transactions which occurred prior to the current calendar year but which were not recorded in the books of account shall be included in the same accounts which would have been charged or credited if the items had not been delayed; provided, that when the amount of a delayed item is relatively so large that its inclusion in the accounts for a single month would seriously distort the accounts, it may be distributed in equal amounts to the accounts for the current and remaining months of the calendar year; and provided further, that, if the amount of any delayed item is relatively so large that its inclusion in the accounts for a single year would seriously distort the accounts, the amount shall be included in account 434, Miscellaneous Credits to Surplus, or account 435, Miscellaneous Debits to Surplus, unless the Department shall prescribe otherwise in specific instances.
