Kaisa Group has unveiled its long-awaited debt workout plan to avoid a showdown during next month's liquidation court hearing in Hong Kong, the first time the Shenzhen-based developer is restructuring its finances since defaulting on US$12 billion of offshore bonds in 2021.

The developer offered its creditors several payment options, including new notes denominated in US dollars, and mandatory convertible bonds (MCB) that can be exchanged into new Kaisa shares, according to a filing to the Hong Kong stock exchange on Tuesday.

Six tranches of senior notes totalling more than US$5 billion and eight tranches of MCBs with an aggregate principal amount of US$4.8 billion will be allocated to creditors, based on their respective ratios in the workout scheme, according to the plan.

In addition, the developer may issue new shares one or more times to existing shareholders, to which its founder Kwok Ying-shing and his brother Kwok Ying-chi will contribute 115 million yuan (US$16.1 million) in the form of a shareholder loan, Kaisa said.

The restructuring plan had been agreed by a group of bond holders with more than 34 per cent of Kaisa's debt and over 36 per cent of the debt in Kaisa's Rui Jing unit, the company said.

"The contemplated restructuring is intended to provide the company with a long-term runway to stabilise the business, and allow adequate financial flexibility to achieve a sustainable capital structure and enhance its net asset value, and protect the rights and interests, and maximise value, for all stakeholders," Kaisa said.

The workout has been long overdue for Kaisa, which has 226.4 billion yuan in total liabilities. The company has spent more than two years on its restructuring plan since missing its payments in late 2021.

Frustrated creditors and bond holders had taken to Hong Kong's law courts to recover their investments. Citicorp International, the trustee of a group of bond holders, joined the queue of petitioners against Kaisa in March after a previous claimant withdrew.

The Hong Kong High Court is scheduled for a hearing on September 9 on Kaisa's fate. Its proposal rekindled hopes that the developer would be able to reach a debt restructuring and avoid a potential liquidation.

Separately on Tuesday, Guangzhou-based R&F Properties announced it has received two separate wind-up petitions against its unit Trillion Glory and R&F Properties (HK). The wind-up hearing against Trillion Glory was scheduled to be heard at Hong Kong's High Court on September 25 while the hearing against R&F Properties (HK) was set on October 30.
