3i Infrastructure outperformed its year targets thanks to a strong infrastructure market, the company said on Thursday. The private equity firm also said that it had managed to raise £115 million to invest in more assets around the world.

3i said that had invested 88 per cent of net IPO proceeds raised last year, around £613 million, and added that it had delivered a return of 13.1 per cent on opening shareholder's equity.

The company said that both results were ahead of the stated objectives of the IPO.
