At the beginning of 2021, Terra Lumber Company purchased a timber tract from Boise Cantor for $4,300,000. After the timber is cleared, the land will have a residual value of $660,000. Roads to enable logging operations were constructed and completed on March 30, 2021. The cost of the roads, which have no residual value and no alternative use after the tract is cleared, was $364,00. During 2021, Terra logged 640,000 of the estimated 6.4 million board feet of timber. Required:
Calculate the 2021 depletion of the timber tract and depreciation of the logging roads assuming the units-of-production method is used for both assets. (Do not round intermediate calculations.)
1. Depletion of the timber tract
2. Depreciation of the logging roads

Annuity payments are assumed to come at the end of each payment period (termed an ordinary annuity). however, an exception occurs when the annuity payments come at the beginning of each period (termed an annuity due). what is the future value of a 13-year annuity of $2,800 per period where payments come at the beginning of each period? the interest rate is 9 percent. use appendix c for an approximate answer, but calculate your final answer using the formula and financial calculator methods. to find the future value of an annuity due when using the appendix tables, add 1 to n and subtract 1 from the tabular value. for example, to find the future value of a $100 payment at the beginning of each period for five periods at 10 percent, go to appendix c for n = 6 and i = 10 percent. look up the value of 7.716 and subtract 1 from it for an answer of 6.716 or $671.60 ($100 × 6.716)
