This applies in particular to conversion efficiency and CSMproduction estimates, and to productivity estimates.• The calculation assumes that there are no conversion losses between the stump site andthe point of sale in the market (where the production figure was estimated). Inclusion ofconversion losses would increase the employment estimate at each stage except retail.• The calculation ignores the possible contribution of chainsawn lumber entering the legalchain. Inclusion would increase the number of workers at the stump site and the haulageemployment estimates.• The calculation ignores home consumption and direct sales that do not go through themarket. Inclusion would increase the number of workers at the stump site and the haulageemployment estimates.• The calculation assumes full-time involvement of workers and ignores indirect jobscreated by CSM.
