SINGAPORE/HONG KONG:  The new head of Singapore Exchange Ltd, which was hit hard in its derivatives trading by China's economic slowdown, could face his toughest questions yet at an annual shareholders' meeting on Wednesday as pressure mounts to find new sources of revenue.

Trading in one of the exchange's key futures contracts for Chinese shares has slumped by nearly three-fourths from a record high hit in early July, Thomson Reuters data shows, at a time when its derivatives business has been growing and contributes a rising share of its revenue.
