Hi Evan,
After reading the official news, only US shareholders which should include holders of ADSs (via ADRs) will receive cash in-lieu of the distribution-in-specie in JD.com shares. These US shareholders if the cash in-lieu is above HK100, they will receive cash, else the cash will be retained by Tencent due to certain reasons such as inefficiency to distribute such amount.
Shareholders who own Tencent shares listed in the US OTC markets are ADS holders, which the equivalent number of ADRs are held with a Depositary Bank in US, which are likely to be registered with a US address, therefore they should be deemed as shareholders with US address, which will receive cash-in-lieu.
