As a firm grows, it must support increases in revenue with new investments in assets. The self-supporting, or sustainable, growth model helps a firm assess how rapidly it can grow, while maintaining a balance between its cash outflows (increases in noncash assets) and inflows (funds resulting from increases in liabilities or equity). Consider the following case of Blue Elk Manufacturing: Blue Elk Manufacturing has no debt in its capital structure and has $300,000,000 in assets. Its sales revenues last year were $120,000,000 with a net income of $2,000,000. The company distributed $180,000 as dividends to its shareholders last year. Given the information above, what is Blue Elk Manufacturing's sustainable growth rate? 4.15% 0.52% 0.06% 0.61% Which of the following are assumptions of the sustainable (self-supporting) growth model? Check all that apply. The firm maintains a constant ratio of assets to equity. The firm uses all equity and no debt financing. The firm's total asset turnover ratio remains constant. The firm must issue the same number of new common shares that it issued last year
