Account 156 " Provisions for the renewal of fixed assets (concession companies) " records provisions for the renewal of fixed assets set up by public service concession companies.

Account 157 " Provisions for deferred expenses " records provisions intended to cover foreseeable, significant expenses that are not annual in nature, such as major repairs, and which consequently cannot be supported in the financial year in which they are incurred.

When a provision is made, the provision account is credited by debiting:

• Account 681 " Depreciation, amortization, impairment and provisions - Operating expenses " when it affects operations;

• Account 686 " Amortization, impairment and provisions - Financial expenses " when it affects the entity's financial activity;

• Account 687 " Depreciation, amortization, impairment and provisions - Exceptional expenses " when it is of an exceptional nature.

It is readjusted at the end of each financial year by:

• debiting the corresponding accounts 681 , 686 or 687 , when the amount of the provision is increased;

• crediting account 781 " Reversal of depreciation, amortization, impairment losses and provisions (Operating income) " , account 786 "  Reversal of provisions for liabilities and impairment losses (Financial income) " or account 787 " Reversal of provisions and impairment losses (Exceptional income) " when the amount of the provision is to be reduced or cancelled, as the provision has become wholly or partly irrelevant.

When the risk is realized or the expense occurs, the previously made provision is balanced by crediting accounts 781, 786 or 787. At the same time, the expense incurred is recorded in the relevant account of Class 6.
