Amendments to the standard for FRS 101 preparers

Where an entity applies FRS 101, it is preparing Companies Act accounts rather than IAS accounts. Therefore the following amendments must be made to IFRS 3 in order to achieve compliance with the Companies Act and related Regulations:

  1. In the case of a bargain purchase, the excess is recognised on the face of the statement of financial position. Subsequently the excess is measured in profit or loss over a specified period.
  2. Where the cost of a business combination may be adjusted due to consideration which is contingent on future events, the estimated amount of the adjustment is included in the cost of the business combination at the acquisition date if the adjustment is probable and can be measured reliably. If the potential adjustment is not recognised at the acquisition date but later becomes probable and can be measured reliably, the additional consideration is treated as an adjustment to the cost of the business combination. From 1 January 2016 this guidance on contingent consideration is amended to require that contingent consideration balances arising from acquisitions before SI 2015/980 is applied (usually 1 January 2016) are not adjusted as a result of changes in company law and the company's previous accounting policy continues to apply. Contingent consideration balances arising from acquisitions after SI 2015/980 is applied are accounted for in accordance with IFRS 3, without amendment to the standard.

Disclosure exemptions for FRS 101 preparers

FRS 101 paragraph 8(b) states that a qualifying entity is exempt from most of the IFRS 3 disclosure requirements in respect of business combinations during the period or after the end of the period provided that equivalent disclosures are made in the consolidated financial statements of the group in which the entity is consolidated. The following basic disclosures are still required:

  • The name and a description of the acquiree;
  • The acquisition date and percentage of voting equity interests acquired;
  • The acquisition date fair value of consideration transferred, in total and by class;
  • Amounts recognised at acquisition for each major class of assets and liabilities;
  • The gain recognised in a bargain purchase;
  • The non-controlling interest recognised at acquisition and measurement basis applied;
  • The revenue and profit or loss of the combined entity for the current period as though the acquisition date for any mid-period business combination was the start of the period.

IFRS 3 paragraphs for which exemption is available: 62, B64(d), B64(e), B64(g), B64(h), B64(j)-(m), B64(n)(ii), B64(o)(ii), B64(p), B64(q)(ii), B66, B67.
