The proposed Sabana REIT merger with ESR threw up another disadvantage of custodian - the one proxy rule which might sometimes happen.

In their letter to MAS, Quarz and Black Crane said certain custodian banks were determining their proxy vote using either an "offsetting" or a "simple majority" rule.
One major custodian bank, in client communications seen by BT, said it will collate all clients' instructions and indicate a vote based on the collective majority choice.
Assuming investors A and B held Sabana Reit units via this custodian bank, and A submits three votes in favour while B submits two votes against, under the simple majority rule, the custodian would submit three votes in favour but would submit no votes against the merger.
Meanwhile, under the offsetting rule, which at least one other bank will use, the same situation as described above would see the custodian submit only one vote in favour. The votes against would be offset by the votes in favour.
