BUSINESSMEN and beauties alike had reason yesterday to see the world through tinted glasses - or at least the spectacle of Moulin International Holdings' promotion for its coming flotation. The $100 million issue, to be sub-underwritten today and sponsored and managed by Lippo Asia, will be offered from September 15 to 20. Moulin's net profit soared 82 per cent to $22.89 million for the year to March 31, after surging 92 per cent in the previous year. Turnover rose 42 per cent to $173.25 last year, after posting a 41 per cent increase previously. A source forecast that the company's profit for the year to March 1994 would be about $50 million. The price-earnings multiple was expected to be just over eight times. Chairman and managing director Ma Bo-kee said the volume of contracts secured so far this year already exceeded last year's total. Its own production made up about 86 per cent of sales, with the balance contributed by trading activities. Despite a mainland-dominated manufacturing base and the right to sell 20 per cent of output there, Moulin is in no rush to boost its sales in China, which is served only after demand from foreign markets has been met. In the year to March 31, China accounted for 27 per cent of turnover and Mr Ma expected that figure to drop to about 13 per cent this year. ''We've reduced our China sales because we've been very busy with the overseas markets,'' he said. For similar products, profit could be 20 per cent higher from exports than China sales. ''And as soon as a new brand starts to sell well in China, it will be imitated,'' he added. ''Thus we'll be cutting back on mainland sales. We don't dare launch many products in China because that will only invite copycats.'' Last year, the United States accounted for 40 per cent of sales, Canada six per cent, Asia 16 per cent and Europe seven per cent. Mr Ma said the territory's spectacle makers ranked among the best globally and were competing fiercely with their Italian counterparts.
