On january 1, 2018, the allegheny corporation purchased machinery for $150,000. the estimated service life of the machinery is 10 years and the estimated residual value is $7,000. the machine is expected to produce 300,000 units during its life. required: calculate depreciation for 2018 and 2019 using each of the following methods.
1. straight line.
2. sum-of-the-years'-digits.
3. double-declining balance.
4. one hundred fifty percent declining balance.
5. units of production (units produced in 2018, 43,000; units produced in 2019, 38,000).

Calculate the cost of each capital component—in other words, the after-tax cost of debt, the cost of preferred stock (including flotation costs), and the cost of equity (ignoring flotation costs). use both the capm method and the dividend growth approach to find the cost of equity. calculate the cost of new stock using the dividend growth approach. what is the cost of new common stock based on the capm? (hint: find the difference between re and rs as determined by the dividend growth approach and then add that difference to the capm value for rs.)assuming that gao will not issue new equity and will continue to use the same target capital structure, what is the company’s wacc? e. suppose gao is evaluating three projects with the following characteristics. each project has a cost of $1 million. they will all be financed using the target mix of long-term debt, preferred stock, and common equity. the cost of the common equity for each project should be based on the beta estimated for the project. all equity will come from reinvested earnings. equity invested in project a would have a beta of 0.5 and an expected return of 9.0%.equity invested in project b would have a beta of 1.0 and an expected return of 10.0%.equity invested in project c would have a beta of 2.0 and an expected return of 11.0%.analyze the company’s situation, and explain why each project should be accepted or rejected g
