Capital Income: Capital incomes are those incomes that do not arise in the normal course of business operations. Such incomes arise from the capital itself, without involving any production work. For example, premium received from the issue of shares or debentures.
The capital expenditure results in an income or benefits for a longer period that extends for a period of more than a year. This expenditure is shown in the Balance Sheet
A promissory note is an unconditional promise in writing given by the buyer (or creditor) to the seller (or debtor) to pay the amount of money specified therein to the seller or to the order of seller or to bearer.
