The filing is expected to be approved in mid-May and the firm will start trading on the Stock Exchange of Thailand in June, CEO Sigve Brekke said yesterday.

DTAC will be the first company to list on both the Thai stock market and an overseas bourse. It is listed on the Singapore Exchange.

On April 30, both DTAC and United Communication Industry (Ucom) will hold a shareholder meeting to seek approval for DTAC's plan to swap its shares with Ucom and for its listing.

Under the listing plan, DTAC will offer 222 million shares to the public to raise Bt7 billion to Bt8 billion following a 1:5 par split.

Thailand's second-largest mobile-phone service provider will also issue 847.69 million shares at Bt2 par value to swap with the entire Ucom stock at a ratio of 1.95 DTAC shares for one Ucom share. This will pave the way for Ucom's delisting.

Ucom owns 43.1 per cent of DTAC and become DTAC's wholly owned subsidiary after the share-swap.
