a paste that can be sold to Colgate Palmolive Limited. The paste is considered
insignificant in value and can only be sold for a nominal market value. The cost assigned
to the paste is its market value less incremental cost incurred subsequent to the point of
split-off. Information concerning a batch produced in June 2014 at a joint cost of
