Paragraph 10

Provisions for diminution in value shall be made in respect of any fixed asset which has diminished in value if the reduction in its value is expected to be permanent (whether its useful economic life is limited or not), and the amount to be included in respect of it shall be reduced accordingly, and any such provisions which are not shown in the income and expenditure account shall be disclosed (either separately or in aggregate) in a note to the accounts.

Where the reasons for which any provision in respect of fixed assets (whether or not it is one to which subparagraph (1) above applies) was made have ceased to apply to any extent, that provision shall be written back to the extent that it is no longer necessary, and any amounts written back in accordance with this subparagaph which are not shown in the income and expenditure account shall be disclosed (either separately or in aggregate) in a note to the accounts.
