UK’s aerospace and defense group, Rolls-Royce has said that it has provided information relating to incidences of bribery and corruption involving its intermediaries overseas to the investigators in the UK.

The world's second-largest maker of aircraft engines said that it provided the information to the investigators following a request for information from Britain's Serious Fraud Office about allegations of bribery and corruption in its units in Indonesia and China.

The company said that it has identified certain matters of concerns in its units in foreign countries. SFO had asked Rolls to investigate allegations of corruption in China and Indonesia. The company had hired an independent body to investigate the matter and has passed on the results to the SFO.

chief executive John Rishton said in a company statement that, “I want to make it crystal clear that neither I nor the board will tolerate improper business conduct of any sort and will take all necessary action to ensure compliance. This is a company with exceptional prospects and I will not accept any behaviour that undermines its future success.”

The shares of the company fell as much as 5 per cent in early trading today to 870p, recording biggest faller in the FTSE 100 ever. The shares of the company have risen 25 per cent this year yet.
