US buyout firm Kohlberg Kravis Roberts has implemented a more attractive fee structure on its infrastructure fund, in a move that could place pressure on other private equity houses to adapt their terms amid a difficult fundraising environment.

The fund will charge investors 1% in management fees and 10% in carry, the profit made on investments. The reduced figures, which are more common in infrastructure funds due to the longer life of the funds, are half of the usual two and 20 model for private equity but will not apply to KKR's buyout funds.
