H Ltd. received a specific grant of Rs. 30 lakhs for acquiring the plant of Rs. 150 lakhs during 2016-17 having useful life of 10 years. The grant received was credited to deferred income in the balance sheet and was not deducted from the cost of plant.

During 2019-20, due to non- compliance of conditions laid down for the grant, the company had to refund the whole grant to the Government. Balance in the deferred income on that date was Rs. 21 lakhs and written down value of plant was Rs. 105 lakhs.

What should be the treatment of the refund of the grant and the effect on the cost of the fixed asset and the amount of depreciation to be charged during the year 2019-20 in the profit and loss account?
