So, who's who in Noble's independent board committee?

EMBATTLED commodity group Noble announced on Tuesday that its board has set up an independent board committee consisting of four non-executive independent Noble board members.

The committee comprising Paul Brough (as chairman), Irene Lee, Richard Margolis and Christopher Pratt in turn has appointed PricewaterhouseCoopers LLP (PwC) to conduct an assurance review of Noble's MTM models, valuations, and governance framework - contentious issues raised by critics.

BT takes a closer look at these members:

Paul Brough: Mr Brough came to Hong Kong in 1983 to join KPMG, where he became a partner in 1991, and later the senior partner. He retired from KPMG in 2012.

He is an associate of the Institute of Chartered Accountants in England and Wales, the Hong Kong Institute of Certified Public Accountants and the Hong Kong Securities and Investment Institute.

He has been appointed as Noble's independent non-executive director with effect from May 6, 2015.

He is an independent non-executive director of Singapore-listed GuocoLeisure and a non-executive director of Habib Bank Zurich (Hong Kong).

He stepped down as the chairman and CEO of Emerald Plantation Holdings Limited (EPHL) on April 1, 2015, and resigned from the EPHL board on April 15, 2015; and was an executive director and interim CEO of Hong Kong-listed Greenheart Group until he was re-designated as a non-executive director effective April 2, 2015.

Irene Lee: Ms Lee has held senior positions with a number of global financial institutions involved in investment banking and fund management over the past 30 years.

She had been an executive director of Citicorp Investment Bank Limited in New York, London and Sydney and head of corporate finance at Commonwealth Bank of Australia and CEO of Sealcorp Holdings, both based in Sydney.

She is the executive chairman of Hysan Development Company, an independent non-executive director of Cathay Pacific Airways Limited, CLP Holdings Limited, Hang Seng Bank Limited and The Hongkong and Shanghai Banking Corporation Limited.

Richard Margolis: A former diplomat, Mr Margolis currently holds senior advisory roles with the Holdingham Group, Rothschild (Investment Bank) and Milestone Capital.

He was managing director, corporate finance, at Smith New Court Far East, and head of strategy and planning for Asia Pacific at Merrill Lynch.

From 2003 to 2011, he was the regional director, north-east Asia, for Rolls-Royce. Mr Margolis was awarded the CBE (Commander of the Order of the British Empire) in 2011 for services to British business in China.
