The budgeted and actual results of the East Midlands branch of Ericka Ltd are now available and Adam Monkman, Chief Accountant, is concerned that top management are proposing to reward the team with a bonus. Adam has met with the top management, stating "The current arrangement of awarding bonus payments based on sales figures does not make sense. The arrangement is far too generous and does not promote economic responsibility for overall results. If bonuses are paid, I suggest linking such payments to profit figures." Top management have responded with the following statement "We are not evading our responsibilities as a senior team overseeing the performance of the East Midlands branch. It is a known fact that we are operating in a challenging economic environment. Exceeding our sales targets deserves a bonus!"
