BRUSSELS, Nov 6 (Reuters) - Corning faces an EU

antitrust investigation over exclusive supply deals with mobile

phone makers and raw glass processing companies that may exclude

rival glass producers from large segments of the market,

regulators said on Wednesday.

The U.S. company, which sells a break resistant glass used

as a cover for mobile phones, tablets and smart watches under

the Gorilla Glass brand, said it was committed to complying with

all applicable rules and regulations where it does business.

"As part of that commitment, we work with local regulatory

authorities to ensure open discussion and cooperation," the

company said in an email.

The European Commission said in a statement that it would

assess whether Corning abused its dominant position in the

global market for glass used mainly in mobile phones.

"We are investigating if Corning, a major producer of this

special glass, may have tried to exclude rival glass producers,

thereby depriving consumers from cheaper and more

break-resistant glass," EU antitrust chief Margrethe Vestager

said.

The EU's investigation will focus on exclusive sourcing

obligations, exclusivity rebates and clauses requiring phone

makers to inform Corning about competitive offers and accepting

these offers only if Corning fails to match the price.

It will also look into Corning's deals with companies that

process raw glass that include exclusive purchase obligations

and no challenge clauses.

The EU watchdog said Corning may now offer concessions to

address its concerns, a move which could help Corning stave off

a possible hefty fine without any finding of wrongdoing.

Companies risk fines as much as 10% of their global turnover

if found to be in breach of EU antitrust rules.
