Caiman Distribution Partners is the Brazilian distribution company of a U.S. consumer products firm. Inflation in Brazil has made bidding and budgeting difficult for marketing managers trying to penetrate some of the country's rural regions. The company expects to distribute 450,000 cases of products in Brazil next month. The controller has classified operating costs (excluding costs of the distributed product) as follows: Account Operating Cost Behavior Supplies $ 360,000 All variable Supervision 220,000 $ 160,000 Fixed Truck expense 1,185,000 $ 180,000 Fixed Building leases 840,000 $ 540,000 Fixed Utilities 210,000 $ 115,000 Fixed Warehouse labor 870,000 $ 145,000 Fixed Equipment leases 755,000 $ 600,000 Fixed Data processing equipment 980,000 All fixed Other 850,000 $ 400,000 Fixed Total $ 6,270,000 Although overhead costs were related to revenues throughout the company, the experience in Brazil suggested to the managers that they should incorporate information from a published index of Brazilian prices in the distribution sector to forecast overhead in a manner more likely to capture the economics of the business. Following instructions from the corporate offices, the controller's office in Brazil collected the following information for monthly operations from last year: Month Cases Price Index Operating Costs 1 350,000 117 $ 5,739,139 2 367,000 119 5,846,638 3 363,000 120 5,889,905 4 385,000 124 5,967,617 5 379,000 126 5,979,135 6 400,000 127 6,083,364 7 372,000 130 5,958,495 8 417,000 135 6,173,868 9 403,000 135 6,166,130 10 426,000 134 6,226,625 11 422,000 138 6,248,799 12 437,000 141 6,402,255 These data are considered representative for both past and future operations in Brazil.
