The resilience of airports


Airports have become important assets in most infrastructure funds, and investors should consider whether the fundamentals will ensure the strong past performance is likely to continue in the future.

Since the development of commercial aviation during the post-World War II era, passenger volumes at major commercial airports have grown at multiples of GDP over any medium-term period. This growth reflects many underlying factors including increasing wealth, real reductions in the cost of air travel, developments in aircraft technology and improvements in international airspace regulation.

Global passenger growth is illustrated in Chart 1 below, showing the fairly consistent growth of airline passenger volumes since the mid-1960’s and more recently, this measure has grown by 62% over the last 10 years [Airbus, 2015]. More importantly, the chart illustrates the resilience of air travel to external shocks and the speed of the recovery to a long term upward trajectory.

High quality airports benefit from a near monopoly stream of passengers from which they are able to generate both aeronautical and commercial revenues. Regulation is structured to allow the aeronautical operations (including passenger, landing and ancillary fees) to earn returns in line with the cost of capital, whilst there are typically no restrictions placed on the returns that can be generated from non-aeronautical operations, such as retail, parking and commercial property.

ADP is the owner and operator of the Paris airport system. This includes both the Charles de Gaulle and Orly Airports. In 2014 these airports handled 92.7 million passengers, making it the second largest system in Europe after London.

Key points on Paris airports:

  • Passenger traffic at the Paris airports was up 3.0% over 2015
  • This was despite the shock of Paris seeing its second terrorist attack in November 2015
  • Chart 2 below shows the very material impact of the terror attacks in November 2015 (with drops of around 4% in traffic for November and December)
  • However, by January 2016 passenger traffic had recovered back to 0.9%, with Air France and ADP both reporting that volumes are back to usual
  • This is a clear demonstration of the resilience of airports and the ability to bounce back from short-term passenger shocks

SYD is owner and operator of the Sydney domestic and international airport. In 2015 SYD handled approximately 40 million passengers. The long term resilience is equally evident with SYD as illustrated in Chart 3 below.

  • The notable external shock within the Australian context was the collapse of Ansett Australia in 2001. Ansett was Australia’s second largest domestic airline.
  • The rising middle class, particularly in Asia has been contributing to strong passenger growth

In summary, airports form a core part of Magellan’s definition of infrastructure and have, over time, delivered robust financial performance and generated healthy returns for investors. We believe that airports remain a global growth sector and offer an attractive balance of regulated and competitive earnings potential.

    Vishal – thank you for your question.

    Magellan is very comfortable with the level of debt held by the airports we are invested in. In fact, the debt level is generally less than what it was a decade ago.

    Of the airports in our portfolio, the current average debt as measured by Net Debt to Enterprise Value is 23% (compared to 33% across the entire portfolio) with an average Debt Service Cover Ratio i.e.( Revenue – Operating Costs)/Interest Costs of 9.6. That means they are producing almost 10 times as much operating cash flow as they need to meet their annual interest costs.

    While airports are more risky than some other sectors in which we invest such as regulated utilities, their earnings have shown to be very resilient to shocks such as 9/11 and the GFC.

    Great article Gerald. One question though, what’s your view on the level of debt airports generally hold?

    I would challenge the central claim that airport traffic volumes are “resilient to external shocks” because the charts demonstrate the opposite. The charts look exactly like real GDP charts – with the same drawdowns at the same times – ie they are a good proxy for economic activity – ie cyclical – the opposite of resilience. This makes sense because 2/3 of economic activity is household spending and air travel is discretionary and falls in economic recessions – same with business travel. But the claim of resilience is the essence of their case for owning them.
