As with any other business, an airport is valued on the basisof its current and expected revenues, earnings and cash flow.

A business model is essentially the method of doingbusiness by which a company can sustain itself – that is,generate revenue.
Selling the provision of infrastructure (massive capex) andsupport services (opex) in the (regulated) marketplace.

The Roots of Key Value Drivers
• Operating Efficiency, i.e.: → ROS - Infl.-Adj. Total Revenue/WLU
- EBITDA Margin - Cash Flow/Total Revenue • Asset Utilization, i.e.: → Asset Turnover - WLU/Total Assets
- Capex/Total Revenue - Capex/Depreciation • Capital Structure, i.e.: → Financial Leverage - Net Assets/Total Assets
- Gearing (Debt/Equity Ratio) - Debt Ratio (Post-Tax)

Frame of Reference: The Airport Value Tree
The airport value tree is rooted in traffic. It summarizes the relationshipsbetween investment, asset turnover, profit margin and financial leverage.

The three Drivers of Return
Du Pont formula: ROA = Profit Margin x Total Asset Turnover
ROI (ROE) can be split into three components / drivers,
turnover of total assets, return on sales, financial leverage:
Net Income = Total Revenue x Net Income x Total AssetsShareh. Funds Total Assets Total Revenue Shareh. Funds
while asset turnover x return on sales (ROS) = return on assets (ROA),
hence
Enhanced Du Pont equation: ROE = ROA x FinancialLeverage

ROS (Return on Sales) Net Income over Total Revenue Total Asset Turnover Total Revenue over Total Assets Financial Leverage Total Assets over Shareholders’ Funds The size of the bubble is determined by financial leverage.
The position of the bubble is determined by ROS and asset turnover. Illustration derived from MSDW, 2000

Balance Sheet Structures of Sample Airports
Publicly owned airports assume more debt relative to their shareholders‘funds, resulting in higher gearing and financial leverage, compensatingfor the comparatively low ROA generated by the business.
Financial leverage is the use of fixed financing costs; it is acquired bychoice, used to increase the return to common shareholders.

The Driver-Based Valuation Approach:Framework & Drivers Revisited
The three drivers of return are: 1. operating efficiency ROS,2. Asset utilization/capital productivity total asset turnover and3. capital structure financial leverage.
16
ROA and ROE of publicly owned, partially and fully privatisedairports are based on considerably different intensities of thesame key drivers.

Positioning of Paired-Sample AirportsBefore and After Partial or Full Privatisation
The positioning of sample airports changes significantly with an increasein the degree of privatisation:
Capex grows faster than revenue decreased asset utilization /capital productivity and asset turnover.Operating margin and ~ efficiency increase on average increasedreturn on sales.Financial leverage decreases higher equity commitment !

Managing the Value of Airports
Maximising capacity utilization appears to be the formula forsuccess in the airport business. This requires projectmanagement and financial skills for a thorough phasing ofcapex and optimisation of the use of debt facilities and equitysupply.
‘Sweating’ the assets includes efficient management oftraffic flows and optimal allocation of capital, finallymaximizing the effectiveness of investment spending, returnrates and shareholder value.
Criteria for (strategic) investments: growth and commercialpotential, potential for margin growth, existing capacity,appropriate regulatory framework and capital financestructure.
22
Conclusions
Airport economics are dominated by the investment cycle; and although footed on the same business model, not allairport earnings are created equal.
Airports should not be valued with a single multiple but withmeasures recognising the key features of success of theirbusiness model and value tree.
It is useful to analyse the intensity and changes of the key drivers: return on sales, asset turnover and financialleverage.
Identifying the distinct differences in terms of operatingefficiency, capital productivity and capital structure is theadded value of this alternative, driver-based valuationapproach.
