Senator WONG (South Australia—Leader of the Opposition in the Senate) (14:26): My question is to the Minister representing the Treasurer, Minister Cormann. In the government's tax discussion paper Re:think tax, issued in 2015, the following statement was included: There are some revenue concerns with the refundability of imputation credits. Can the Minister representing the Treasurer advise what were the concerns raised regarding the refundability of imputation credits?
