Guoyuan Securities Co. Ltd. plans to issue up to 6 billion Chinese yuan worth of convertible bonds.

The six-year notes, whose coupon rate is yet to be determined, can be converted into China-listed shares.

Proceeds will go toward expanding the company's credit business, optimizing its brokerage operations and boosting investment into its asset management operations, among others, according to May 18 filings.
