SINGAPORE--Manulife US Real Estate Management Pte. Ltd. said it will delay a planned US$465 million initial public offering here due to volatile market conditions, the latest firm to fall victim to weak investor sentiment.

The company, a unit of Canadian insurer Manulife Financial Corp., started taking orders from investors last week, but demand for the real-estate investment trust's units didn't meet the company's expectations, people with knowledge of the deal said.

"In light of increased volatility in the equity capital market, the IPO of Manulife US Real Estate Investment Trust has been delayed. Depending on market conditions, the IPO is expected to proceed at a later date," the company said in a statement.

Sentiment toward new offerings has been weak, and Asia's equities markets have turned volatile in the past week due to uncertainty about economic growth in China and the debt crisis in Greece. Expectations of a possible rise in interest rates in the U.S. this year have also been prompting investors to move out of some Asian markets.

China's Shanghai Composite Index fell 12% last week. Singapore's main index rose, but has been volatile this year and has fallen 0.7% since January.

Other firms have also suffered. In May, an Indonesian telecom-tower operator partly owned by Carlyle Group postponed a planned share sale that could have raised up to US$300 million, because of weak market conditions. In March, two firms in Malaysia--a helicopter firm partly owned by KKR and the automotive arm of Malaysia's Sime Darby Bhd., the world's largest listed palm-oil producer--also pushed their IPOs to next year, citing similar reasons, people with knowledge of those deals said earlier.

Manulife US Real Estate lodged its preliminary IPO prospectus with the Monetary Authority of Singapore last week, which showed that the company was seeking to raise 629 million Singapore dollars in gross proceeds. The IPO, if successful, would have been the biggest offering in Singapore so far this year. The company was planning to sell the units at 82 Singapore cents (61 U.S. cents) a unit and had committed to pay a 6.3% yield for 2016, the prospectus showed.

It had also secured six cornerstone investors, who had agreed to take up units of the Singapore REIT ahead of the IPO. Having such investors helps bankers and the company market the deal to other institutional and retail investors.

The cornerstone buyers included sovereign-wealth fund Oman Investment Fund, Nikko Asset Management and Malaysia's Fortress Capital Asset Management.

Singapore is home to nearly 59 real-estate investment and other trusts, with a combined market capitalization of close to S$100 billion. Investors are drawn to their yields, which at about 6% or 7% a year exceed the 0.25% offered on 12-month Singapore-dollar deposits.

Only a few U.S. companies have listed in the region. The most recent offering was a US$1.3 billion IPO by the luggage maker Samsonite International SA in Hong Kong in 2011, according to Dealogic, a data provider.

Singapore's IPO market has been weak this year, partly because investors have shown more interest in soaring stocks in mainland China and Hong Kong. Companies have raised US$33 million through IPOs in Singapore this year, compared with US$619 million a year earlier, according to Dealogic.
