Sales and costs are projected to grow at 30% a year for at least the next 4 years. Both current assets and accounts payable are projected to rise in proportion to sales. The firm is currently operating at full capacity, so it plans to increase fixed assets in proportion to sales. Interest expense will equal 10% of long-term debt outstanding at the start of the year. The firm will maintain a dividend payout ratio of 0.50.
