Cinven, the buy-out firm, has disposed of its last remaining portfolio investment in the smaller companies sector with the sale of Electrium, the UK wiring company, to LDC for £38m (€54m).

The buy-out sees Cinven take a £30m loss on an original equity investment of £68m, made six years ago. However, sources close to Cinven said the loss was broadly in line with the FT Engineering and Electricals' index over the period of the investment.
