Airbus has agreed in principle to a settlement with French, British and U.S. authorities over an investigation into allegations of bribery and corruption, it said on Tuesday.

The European planemaker has been investigated by French and British authorities for suspected corruption over jet sales dating back over a decade. It has also faced U.S. investigations over suspected violations of export controls.

Airbus, which dominates with U.S. rival Boeing the commercial airliner market, said it could not comment on precise details regarding its talks with authorities, including how much it expected to pay out in the settlements. Some press reports suggested a figure of around 3 billion euros.

Nevertheless, Airbus shares rose, as analysts and traders welcomed the fact that Airbus was managing to draw a line under the affair. The stock was up 2.3 per cent in early trading.

“Airbus confirms that it has reached agreement in principle with the French Parquet National Financier (PNF), the UK Serious Fraud Office (SFO) and the US authorities,” the Franco-German company said in a statement.

“These agreements are made in the context of investigations into allegations of bribery and corruption as well as compliance with the U.S. International Traffic in Arms Regulations ( “ITAR “). They remain subject to approval by French and UK courts and the U.S. court and regulator,” it said.
