Impairment in Jersey companies (a)(278.6)
At 28 March 2014295.4
  1. The impairment in Jersey companies has occurred as a result of Group restructuring as explained below. This impairment relates to the distribution in specie of loans that had previously been issued by Halfords Finco (Jersey) Limited to Halfords Group plc. Halfords Group plc therefore now records the £278.6m as an intercompany receivable as shown in note 5.

During the year the Group began an exercise in order to restructure the underlying companies of the Group. This exercise led to a delisting of the Eurobonds issued by Halfords Finco (Jersey) Limited to Halfords Holdings (2006) Limited and Halfords Finance Limited and a distribution in specie of these loans up to Halfords Group plc, as well as the winding up of Halfords Finance UK LLP. Subsequent to the year end the intention of the Group is to wind up the two Ireco companies as well as the Jersey companies.

The investments represent shares in the following subsidiary undertakings as at 28 March 2014 and the fair value of share based compensation plans that are awarded to employees of the Company's subsidiary undertakings. The Company has taken advantage of Section 410(2) of the Companies Act 2006 to list only its principal subsidiary and associated undertakings at 28 March 2014. All of these are wholly owned by the Company or its subsidiary undertakings, registered in England and Wales, and operate predominantly in the United Kingdom unless otherwise stated.
