SINGAPORE - Blue-chip rig maker Sembcorp Industries took home the lion's share of top honours at the "Oscars" of the corporate scene on Tuesday evening held at Resorts World Sentosa.

Chief executive Mr Tang Kin Fei clinched the title of best CEO at the Singapore Corporate Awards, among companies with $1 billion or more in market capitalisation listed on the Singapore Exchange.

Sembcorp also bagged a gold award in its size category for having the best managed board, which it shared with DBS Group Holdings. It earned another gold for having the best annual report in its size category.

The awards are jointly organised by the Institute of Singapore Chartered Accountants, the Singapore Institute of Directors and The Business Times.

President Tony Tan was guest of honour.

DBS, which was last year's big winner at the awards, also picked up a silver this year in the best investor relations segment for large capitalisation companies.

Gold for best investor relations under the category went to media group Singapore Press Holdings (SPH).

SPH CEO Alan Chan said in a statement that the award was "an endorsement of our investor relations strategy at SPH. We help the investment community understand the company's plans through regular and timely engagement."

The best CEO for firms with a market cap of $300 million to less than $1 billion was Mr Patrick Chew of Midas Holdings, which makes aluminium parts for trains in China, while Mr Glenndle Sim from energy services provider Mencast Holdings won the prize for small-cap companies.

The best chief financial officer at a large-cap firm was Mr Lee Wai Fai from UOB.

"The general level of corporate governance has improved. This can be seen in the well-rounded quality of the overall candidate pool from which the winners were selected in this year's Singapore Corporate Awards," the Institute of Singapore Chartered Accountants president Gerard Ee said in a statement.
