What will the depreciation be during the first full accounting year (year 2) if the welder has a 6 year depreciable life, a salvage value of $8,000 and is depreciated using the declining-balance depreciation method?

This hp 12c program calculates the optimum crossover point and automatically switches to straight-line depreciation at the appropriate time. The crossover point is the end of the year in which the declining-balance depreciation last exceeds or equals the amount of straight-line depreciation. The straight-line depreciation is determined by dividing the remaining depreciable value by the remaining useful life. Given the desired year and the number of months in the first year, this program calculates the depreciation for the desired year, the remaining depreciable value, and the total depreciation through the current year.

Key in the useful life of the asset in years then press z. Key in the number of years in the income projection period then press § to get the total straight-line depreciation charge. 3.

The technique implicitly assumes that all cash flows are either reinvested or discounted at the computed yield rate. This assumption is financially reasonable as long as the rate is within a realistic borrowing and lending range (for example, 10% to 20%). When the IRR becomes significantly greater or smaller, the assumption becomes less valid and the resulting value less sound as an investment measure. IRR also is limited by the number of times the sign of the cash flow changes (positive to negative or vice versa). For every change of sign, the IRR solution has the potential for an additional answer. The cash flow sequence in the example that follows has three sign changes and hence up to three potential internal rates of return. This particular example has three positive real answers: 1.86, 14.35, and 29. Although mathematically sound, multiple answers probably are meaningless as an investment measure.
Section 13: Investment Analysis 149 File name: hp 12c_users guide_English_HDPMBF12E44 Page: 149 of 209 Printered Date: 2005/7/29 Dimension: 14.8 cm x 21 cm This Modified Internal Rate of Return procedure (MIRR) is one of several IRR alternatives which avoids the drawbacks of the traditional IRR technique. The procedure eliminates the sign change problem and the reinvestment (or discounting) assumption by utilizing user stipulated reinvestment and borrowing rates. Negative cash flows are discounted at a safe rate that reflects the return on an investment in a liquid account. The figure generally used is a short-term security (T-Bill) or bank passbook rate. Positive cash flows are reinvested at a reinvestment rate which reflects the return on an investment of comparable risk. An average return rate on recent market investments might be used. The steps in the procedure are: 1. Calculate the future value of the positive cash flows (NFV) at the reinvestment rate. 2. Calculate the present value of the negative cash flows (NPV) at the safe rate. 3. Knowing n, PV, and FV, solve for i. Example: An investor has the following unconventional investment opportunity. The cash flows are: Group # of Months Cash Flow ($) 0 1 –180,000 1 5 100,000 2 5 –100,000 3 9 0 4 1 200,000 Calculate the MIRR using a safe rate of 6% and a reinvestment (risk) rate of 10%.
