Several factors affect a firm's need for extemal funds. Evaluate the effect of each following facto and place a check next to each factor that is likely to increase a firm's need for extemal capital-that is, its AFN (additional funds needed). Check all that apply. The firm switches its supplier for the majority of its raw materials. The new supplier offers less favorable credit berms and thus reduces the trade credit available to the firm, resulting in a reduction in accounts payable. The firm improves its production system and increases its profit margin. The firm's forecasted sales are unexpectedly increased. Accounts payable and accrued liabilities represent obligations that the firm must pay off. Assuming everything else holds constant, if they increase, the firm's AFN will decrease
