Ontario Teachers’ Pension Plan Board

Teachers’ is the largest single-profession pension plan in Canada. An independent organisation, it invests and administers the pensions of 303,000 active and retired teachers in the Province of Ontario. Teachers’ investments comprise a mix of equities (public and private), bonds, commodities, real assets (real estate, infrastructure and timberland) and absolute return strategies. When Teachers’ started as an independent organisation in 1990, the plan’s assets totalled C$19 billion. Since then, the plan has grown to C$129.5 billion as at 31 December 2012. During this period, the plan achieved an average annual rate of return of 10%, consistent with its investment mandate to administer the pension plan and manage its investments to earn the best possible rate of return at an appropriate level of risk. Teachers’ has an implied credit rating of AAA from Standard and Poor’s and is headquartered in Toronto.

Teachers’ has a dedicated infrastructure investment management arm known as Teachers’ Infrastructure Group (“TIG”). TIG is an internal, highly-specialised investment team formed in 2001 to invest and manage the plan’s infrastructure portfolio. TIG invests in countries that have a stable economic and political environment and have a history of transparent regulation. TIG targets assets that have a long economic life and offer low-risk, reliable, long-term returns linked to inflation that will help pay pension benefits for decades. TIG is primarily a direct investor in private companies and takes an active asset management and governance approach. Since 2001, TIG has developed strong experience in sourcing, financing, executing and managing infrastructure assets around the world. As at 31 December 2012, TIG managed assets valued at approximately C$9.6 billion including water and wastewater, electricity and gas distribution, airports, power generation, high-speed rail, port facilities and pipelines.
