While infrastructure as an asset class has been embraced by pension funds in Europe and Australia alike, in the US it is still a nascent concept. The difference is largely down to a lack of privatisation in the US, where infrastructure historically has been provided by local and state government. In North America, funds such as the C$87.4 billion Ontario Teachers Pension Plan (OTPP) and Canada Pension Plan have looked abroad for investment opportunities in infrastructure, with the OTPP recently acquiring an additional 35.5 per cent stake in UK-based Bristol International Airport in a deal with Macquarie Airports. The fund had acquired a 14.5 per cent stake in 2002, the September purchase lifting its holding in BIA to 50 per cent.
