We use a tight definition of infrastructure assets and seek low-volatility cashflows and inflation protection to achieve diversification benefits with other asset classes such as global equities.

Our investment philosophy

We invest in listed infrastructure companies across the globe that provide essential services to society, typically physical network monopolies such as toll roads, water utilities, electric grids and telecommunication towers. We believe that infrastructure assets have diversification benefits when combined with other asset classes. We use a tight definition of infrastructure assets, while also considering their low-volatility cashflows and inflation protection capability, to achieve a different risk and return profile to global equities, and over the years we have witnessed the more defensive nature of these assets, particularly in down markets.

In our view, this defensiveness is due to the fact these infrastructure businesses provide essential services to a large population, are fundamental to the functioning of society and are critical to future economic growth. They are also less vulnerable to competition, issues affecting the economy and/or commodity prices than companies under a broader infrastructure definition such as ports and satellites.

Since infrastructure assets are long-term, privileged assets, we believe they need to be socially minded and sustainable, which is why we embed ESG and sustainability considerations into the investment process – both to mitigate risk and to identify opportunities. We seek companies that are adapting to and finding investment opportunities in environmental initiatives such as the energy transition.

We see significant trends in infrastructure with associated investment opportunities. These include decarbonisation, particularly in the utility space, the electrification of society and digitalisation, where infrastructure is needed to support the transition. We believe there is a shortage of infrastructure globally and that some of our listed companies will play a key role in the development and enhancement of infrastructure for decades to come.

Finally, by setting strict assets under management capacity limits for our strategy, we can ensure the portfolio consists of our best ideas, and we can move in and out of stocks quickly if necessary.

Our investment approach

We consider potential investments from a strictly selected infrastructure Focus List of around 110 companies across more than 25 countries based on our definition of infrastructure, which is tighter than most peers and all infrastructure indices. Stocks on the Focus List are those we believe provide the strongest combination of inflation protection and low volatility.

We use a fundamental bottom-up approach to identify the key drivers of the business, such as how it earns revenue, the link to inflation, balance sheet strength, how it is regulated and how its contracts or concession agreements work. By conducting deep, fundamental research, meeting with the companies and regulators and building financial models on the companies, we can determine if the cashflows or earnings display low volatility and how the inflation protection works. This helps us assess the valuation of the company based on long-term cashflow analysis. As well as performing well on environmental matters, we look for companies that have good governance, where the management is aligned with us as shareholders and has a sound strategy and a good track record. We combine this bottom-up research with a top-down approach to managing macro risks.

We take a high conviction approach to ensure our strongest stock views are included in the portfolio. As a result, the strategy is expected to have between 25 and 35 global investments at any one time.

While we have a tight definition of infrastructure and strict capacity limits, we remain flexible enough to develop bespoke solutions for clients.
