Freebird, Inc., manufactures three sizes of industrial work benchessmall (S), medium (M), and large (L). The income statement has consistently indicated a net loss for the M size, and management is considering three proposals: (1) continue Size M, (2) discontinue Size M and reduce total output accordingly, or (3) discontinue Size M and conduct an advertising campaign to expand the sales of Size S so that the entire plant capacity can continue to be used. If Proposal 2 is selected and Size M is discontinued and production curtailed, the an- nual fixed production costs and fixed operating expenses could be reduced by $190,000 and $37,800, respectively. If Proposal 3 is selected, it is anticipated that an additional annual expenditure of $113,400 for the salary of an assistant brand manager (classified as a fixed operating expense) would yield an increase of 130% in Size S sales volume. It is also assumed that the increased production of Size S would utilize the plant facilities released by the discontinuance of Size M. The sales and costs have been relatively stable over the past few years, and they are expected to remain so for the foreseeable future. The income statement for the past year ended January 31, 2013, is as follows: Size S M L $1,260,000 Total $4,030,000 $1,320,000 $1,450,000 Sales Cost of goods sold: Variable costs.
