Frankfurt Airport operator Fraport is looking for possible acquisition targets in mature markets, a German newspaper quoted the company's chief financial officer as saying.

Matthias Zieschang said that before the global financial crisis, Fraport was not able to enter markets in developed countries because prices were very high and had focused instead on emerging markets.

"We now have a new situation," he said, adding infrastructure prices have significantly declined.

Before the crisis, prices for airports were valued at 25 times the earnings before interest, tax, depreciation and amortization (EBITDA) but are now at 10 times EBITDA.

"We have liquid assets because money that was planned for expansion could temporarily be used of course also for acquisitions," Zieschang said.

Fraport was able to raise total liquidity of EUR€7 billion (USD$8.67 billion) as part of its plans to expand Frankfurt Airport. He said Fraport's available cash stands now at EUR€2.6 billion.
