Background
Oon Koon Cheng, through Sin Hong Hwa Pte Ltd, sold the shares of Koon Cheng Development Pte Ltd to a company in the USP Group for $32 million. The consideration comprised $24 million in cash and $8 million in USP Group Limited shares. Koon Cheng Development owned industrial properties, including a profitable foreign-worker dormitory that was housing substantially more workers than its regulatory approval permitted. The sale documents disclosed that the dormitory had approval for 320 workers but was then housing approximately 500.
When the sale and purchase agreement was signed, Li Hua executed a letter of undertaking under which he personally agreed, upon written notice after 36 months from completion, to buy back the USP shares issued to Oon for $8 million. Oon exercised the option in 2019, but Li did not complete the purchase. Oon and Sin Hong Hwa sued to enforce the undertaking. Li contended, among other things, that it was merely a comfort letter, lacked contractual intention, certainty, and consideration, and was affected by misrepresentation or illegality associated with the dormitory.
The Court’s Holding
The High Court allowed the claim and held that the letter of undertaking was a valid and enforceable contract. Li was bound by his personal promise to repurchase the shares. The court rejected his attempts to characterize the document as legally ineffective and rejected his defenses based on uncertainty, lack of consideration, misrepresentation, and illegality. It found that the parties had knowingly entered a commercially advantageous transaction and that Li could not avoid the undertaking after taking the transaction’s benefits.
Li breached the undertaking when he failed to buy the shares after Oon validly exercised the option. Applying the usual breach-date measure for publicly traded shares, the court used 3 August 2019 as the valuation date and deducted the shares’ then-market value from the contractual $8 million price. It awarded Oon damages of $7,013,157.95. The court declined to use the lower share price on the date proceedings began or apply a blockage discount because there was no adequate basis to quantify one.
Key Takeaways
- A signed personal undertaking made as part of a commercial transaction may be enforceable even if it is not incorporated into the principal sale agreement.
- A party that knowingly accepts the benefits of a transaction cannot readily escape a related obligation by retrospectively characterizing the arrangement as informal or commercially inconvenient.
- For breach of an agreement to buy publicly traded shares, damages will ordinarily equal the contract price minus the shares’ market value at the date of breach, absent a sufficient basis to depart from that rule.
Why It Matters
The decision illustrates Singapore courts’ objective, commercial approach to determining whether transaction documents create binding obligations. Labels such as “comfort letter” will not displace the substance, wording, and circumstances of a signed undertaking.
It also provides practical guidance on valuing damages for a failed share purchase. Thin trading alone did not justify moving the valuation date, and a claimed blockage discount required a principled evidential basis.
