You need to estimate the value of Laputa Aviation. You have the following forecasts (in millions of dollars) of its profits and of its future investments in new plant and working capital:

Year
1	2	3	4
Earnings before interest, taxes, depreciation, and amortization (EBITDA)	90	110	125	130
Depreciation	10	20	25	30
Pretax profit	80	90	100	100
Tax at 40%	32	36	40	40
Investment	19	22	25	27

From year 5 onward, EBITDA, depreciation, and investment are expected to remain unchanged at year-4 levels. Laputa is financed 40% by equity and 60% by debt. Its cost of equity is 12%, its debt yields 7%, and it pays corporate tax at 40%.
