Taini Ltd (Taini) is a listed mining company that operates in the Bono Region with a ten-year term concession commencing on 1 April 2022. After the expiry of the current mining term, Taini has a duty to rehabilitate the area. These rehabilitations are anticipated to cost GH¢12.09 million on April 1, 2032. On April 1, 2022, the present value of the restoration cost was calculated using the company’s 8% cost of capital at GH¢5.6 million.

Required:
In accordance with IAS 37: Provisions, Contingent Liabilities and Contingent Assets, explain the financial reporting treatment of the above transaction in the financial statements of Taini Ltd for the year ended 31 March 2023.

Any amount recorded at the present value of future cash flows should be adjusted as time passes. The adjustment allows for the fact that the time to maturity is shorter. The adjustment is measured as the opening balance multiplied by the original discount rate.

Here, GH¢5.6 million × 8% gives GH¢0.448 million. This is charged (debited) to profit or loss (finance costs) and increases the present value of the provision (credit entry).

For Odehyieba Plc, given the significant technological changes and adjustments to the plant’s remaining useful life, the following financial reporting treatments apply:

  1. Depreciation adjustment:
    • The carrying value of the plant is GH¢6,000,000 with a remaining useful life of 11 years, which needs to be reduced by 5 years, making the revised useful life 6 years.
    • Revised depreciation charge: GH¢1,000,000 (GH¢6,000,000 / 6).
  2. Decommissioning cost adjustment:
    • The provision for decommissioning is GH¢1,600,000, which remains unchanged, but the timing affects the discount rate.
    • The decommissioning cost adjusted for the revised useful life using the 11% discount rate results in a liability increase of GH¢136,000.
  3. Revaluation surplus:
    • The revaluation surplus of GH¢960,000 should remain in the revaluation reserve until the plant is disposed of.
