(1A) A * car, motor cycle or similar vehicle must not be one of the new assets.
(2) A * capital gain or a * capital loss you make from the original asset is disregarded.
(3) If you * acquired the original asset on or after 20 September 1985, the first element of each new asset's * cost base is:

The first element of each new asset's * reduced cost base is worked out similarly.
Note 1: In some cases the amount you paid to acquire the new asset also forms part of the first element: see Subdivision 124-D (about strata title conversion) and Subdivision 124-O (about FSR transitions).
Note 2: There are modifications to the consequences in Subdivision 124-B (about compulsory acquisition, loss or destruction), Subdivision 124-C (about statutory licences), Subdivision 124-J (about Crown leases), Subdivision 124-L (about prospecting and mining) and Subdivision 124-O (about FSR transitions).
Note 3: No other elements of the cost base of the new asset are affected by the roll-over.
Note 4: There are special indexation rules for roll-overs: see Division 114.
Note 5: The reduced cost base may be modified for a roll-over happening after a demerger: see section 125-170.
