Provisions
Provisions are recognised when the company has a present legal or constructive obligation as a result of past events; it is probable that an outflow of resources will be required to settle the obligation; and the amount of the obligation can be estimated reliably.
Where there are a number of similar obligations, the likelihood that an outflow will be required in settlement is determined by considering the class of obligations as a whole. A provision is recognised even if the likelihood of an outflow with respect to any one item included in the same class of obligations may be small.
Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation. The increase in the provision due to passage of time is recognised as a finance cost.
Restoration and aftercare provisions
Restoration
Full provision is made for the net present value (NPV) of the Company's minimum unavoidable costs in respect of the restoration liabilities at the landfill site which have been capitalised in tangible fixed assets. The group continues to provide for all after care costs over the life of the landfill site based on the volume of waste deposited in the year.
Aftercare
Provision for the care and monitoring of the site post closure is made on the Director's best estimate of future aftercare requirements for the site as a whole for a period of 60 years following the estimated final closure of the landfill as required by the Landfill Directive.
The long term provisions for restoration and aftercare costs are calculated on the NPV of estimated future costs. Current cost estimates are inflated at 3% and discounted at 5% to calculate the NPV. The effect of the unwinding of the discount element is reflected as a finance cost.
The site capacity was increased and aftercare costs reassessed which has meant a higher charge in this year.
Environmental provision
The environmental provision represents the best estimate of future costs in relation to the Environment Agency's ongoing landfill investigation.
Provisions are recognised when the group has a legal or constructive present obligation as a result of a past event, it is probable that the group will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation.
The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the reporting end date, taking into account the risks and uncertainties surrounding the obligation. Where the effect of the time value of money is material, the amount expected to be required to settle the obligation is recognised at present value. When a provision is measured at present value, the unwinding of the discount is recognised as a finance cost in profit or loss in the period in which it arises.
