UK-based private equity and infrastructure firm 3i Group boosted net asset value 19% in the six months to the end of September even as it disclosed "accounting issues" at portfolio company Agent Provocateur.

The company reaffirmed its commitment to spending up to £750 million a year on four to seven new investments, with chief executive Simon Borrows saying on an earnings call: "Expect [it] to be a busy year for investments and divestments."
