News 19 Jan, 2018 New Basis of Charging Calls for Policy Year 2018 Onwards The Club is changing its calling basis,  so that rather than charging its estimated total mutual call (known as“ETC”) as an advance call plus an additional call, the ETC will be charged simply as a total mutual call. The change has been made to simplify terminology and to make the Club’s calling method more readily understandable. There is no change to the amounts payable. Please download our flyer to read the full details of this change.
