In the reset procedure, the profit-based flow is posted as affecting net income. Income is adjusted during accrual/deferral and the amount not yet affecting net income is posted as a liability or asset. The reset procedure generates an offsetting posting which posts the asset or liability back to the profit and loss account. If a profit and loss statement is output in the meantime, it will contain the profit/loss that occurred during the calculation period.
In the case of the difference method, the profit-based flow is posted to an asset or liability item on the due date without affecting net income. These items are then accrued/deferred gradually, affecting net income by degrees.
