Please refer to the definition of 'wages' as applicable in the ESI Act, 1948. You have used abbreviations in your question. But as I understand them, all of them will have to be included in the 'wages' for payment of contributions. Remember that ESI contribution is NOT ONLY ON BASIC AND D.A.
Definition of "Wages"
"Wages" means all remuneration paid or payable, in cash, to an employee if the terms of the contract of employment, express or implied, were fulfilled. It includes any payment to an employee in respect of any period of authorized leave, lock-out, strike which is not illegal, or lay-off, and other additional remuneration, if any, paid at intervals not exceeding two months. However, it does not include:
(a) any contribution paid by the employer to any pension fund or provident fund, or under this Act;
(b) any traveling allowance or the value of any traveling concession;
(c) any sum paid to the person employed to defray special expenses entailed on him by the nature of his employment; or
(d) any gratuity payable on discharge.
