Singapore Telecommunications (SingTel) launches an intensive round of talks with Australia's investment community on Tuesday in a bid to reassure institutions over its planned acquisition of Cable & Wireless Optus. A senior SingTel executives will begin lobbying investment firms in Sydney to address their fears about the underlying merits of the deal and SingTel's corporate disclosure policy, an official said. In addition, SingTel president and chief executive Lee Hsien Yang will on Tuesday host a question-and-answer session for investors in Singapore with C&W Optus chief executive Chris Anderson and chief financial officer Norman Gillespie. The moves come as SingTel stock, which has slumped by more than a fifth since the deal was announced, continued to trade at record lows. It finished 5 per cent weaker on Monday at S$1.83 after hitting an intra-day low of S$1.79. SingTel's takeover of Australia's second-largest telecoms firm has unnerved investors in Singapore and Sydney. Analysts said many remain convinced the price-tag, up to A$16 billion (about HK$60.56 billion) when first announced, was too rich. The deluge of SingTel stock that could be issued to help pay for the cash-and-shares transaction has also contributed to the selling pressure, they said. Seah Hiang Hong, research head at Kim Eng Securities, said the SingTel team in Sydney could face an uphill battle. 'Basically they will be there to allay the fears of Australian fund managers. The stock they are holding now is very different from the stock that they will hold after the takeover goes through,' Mr Seah said. He added that despite the steep slump in SingTel's stock price, the counter may yet to have hit bottom. 'It's had a lot of the premium stripped out because it no longer has a net-cash position,' Mr Seah said. Analysts said the current halt in SingTel's fall had as much to with the inability of traders to borrow stock to sell short as investors having priced in the deal's full implications. Institutional investors account for the majority of C&W Optus stock after Britain's Cable & Wireless, which has pledged its 52.5 per cent holding to SingTel. An indication of the Australian firms' sentiment came from C&W Optus' Mr Gillespie, who told reporters at the weekend 'We have been very open with our investors and they are genuinely worried that there will be a drop in the level of transparency.' Separately on Monday, C&W Optus said it had signed a supply deal with Nokia for third-generation mobile handsets, believed to be worth about A$900 million over seven years.
