Davis Polk & Wardwell and AZB & Partners have advised Reliance Industries Ltd., India’s largest private company, on a $1 billion debt issue on the Singapore Exchange.

Mumbai-based Reliance made the offering of senior notes through a subsidiary based in Delaware. Reliance’s revenue last year was $58 billion, the highest of any Indian company. Its wide-ranging business activities include energy, textiles, telecommunications, and food. The company will use the proceeds of the issue for capital expenditure, investments, refinancing, and general corporate purposes.
