CCME's cash is in China, not HK. In China, 3 month saving earns ~1.7%. Need to check with Jacky though.
10 Q: Page 18: “As of June 30, 2010, CME had net cash of $139.3 million. CME’s cash primarily consists of cash on hand and cash deposited in banks and interest-bearing savings accounts.”
Page 19: “Because all of CME’s earnings and cash balance are denominated in RMB, appreciation or depreciation in the value of the RMB relative to the U.S. dollar would affect CME’s financial results reported in U.S. dollar terms.”
