Pureform, Inc., uses the weighted-average method in its process costing system. It manufactures a product that passes through two departments. Data for a recent month for the first department follow:

The beginning work in process inventory was 80% complete with respect to materials and 65% complete with respect to labor and overhead. The ending work in process inventory was 60% complete with respect to materials and 50% complete with respect to labor and overhead.

Required:

Assume that the company uses the FIFO method in its process costing system.

1. Compute the first department's equivalent units of production for materials, labor, and overhead for the month.

2. Compute the first department's cost per equivalent unit for materials, labor, overhead, and in total for the month. (Round your answers to 2 decimal places.)

Required:

Using the step-down method, allocate the costs of the service departments to the two operating departments. Allocate Administration first on the basis of employee-hours and then Janitorial on the basis of space occupied.

In 1898, the first Putting Green Championship was held. The winner’s prize money was $466. In 2002, the winner’s check was $1049361. What was the percentage increase per year in the winner’s check over this period? ( as a percentage and round to 2 decimal places)

1. The EPA is considering an application from the state of Colorado for a large dam project on the Colorado River. The basic costs and benefits of the project (in inflation-adjusted dollar values) are as follows:

1. Do a formal Cost-Benefit Analysis (CBA) using the quantifiable factors listed above. Assume that the operating lifespan of the dam is 30 years. Assume construction begins in year 1. All other impacts start when the dam is completed (at the beginning of Year 4) and continue for 30 years, which implies the full lifespan for the project is 33 years.
2. Using the same parameters and results from part (a.), adjust the interest rate to determine the level of discounting necessary to just break even. (Hint: I would start by changing the interest rate in 1% increments and then refine the changes as you get close to the break-even point.) What does this increase or decrease in interest rate imply about the relationship between costs and benefits over time?
3. Finally, holding constant the analysis you did in part (c.) what happens when you increase the acre-foot price of irrigation water from $700 to $1500 and/or the price per kilowatt hour of electricity from $0.125 to $0.15?

Which section of the FASB ASC explicitly states whether the 2016 interest on the bank loan qualifies for capitalization? (The citation must follow xxx-xx-xx-xx or xxx-xx-xx-x format)

(The citation must follow xxx-xx-xx-xx or xxx-xx-xx-x format)

Please explain/show all work.

On 11/1/X1 JacobCo Inc. hired an external engineering firm to design a new production line to produce a new fishing lure product line. The design of the new production line was completed on 11/28/X1 and JacobCo. Inc. received an invoice from the engineering firm in amount of $225,000. Construction started on a new production line on 12/8/X1 and was completed on 12/31/X1. The total construction cost of the new production line was $895,000. Interest expense from 11/1/X1 when the project was started to 12/31/X1 when it was completed amounted to $43,000 in total. Of that total interest expense $4,200 was attributable to the new production line.

The production line had an estimated engineering physical life of eight years. It is estimated that the production line could be scrapped and have a salvage value of approximately $30,000 at the end of that time.

The marketing department estimated that the new fishing lure product line would provide revenues to JacobCo. Inc. for the next five years. At the end of that time period the fishing lure product line will be discontinued and the production line will be scrapped and will sold for $10,000. The marketing department also estimates that the total number of fishing lures that will be sold over the next five years will be 500,000 units. The production line started into operation on 1/1/X2.

Required: Calculate depreciation for 12/31/X2 and 12/31/X3 and make the required journal entries using :

A. Straight line depreciation.

B. 200% double declining balance.

C. Units of Production assuming that 102,500 lures were produced in the year ending 12/31/X2 and 91,000 lures were produced in the year ending 12/31/X3.

Suppose that you work for Camden Property Trust (Links to an external site.), a multi-family REIT in the southern US, and that your company wants to add another apartment building to its investment portfolio. After conducting a thorough market analysis, you have narrowed your search to three properties located in different areas in Houston, Texas. All of the properties have a similar number of units, and the units are also similar with regard to mix and sizes. The primary differences is the supply and demand in the different market areas, and the consideration of newer versus older properties

Option 1: The first property is currently built and operating in a middle income area that has a shortage of housing. At this time, the building has no vacancy, but there are some new apartments being built nearby that will soon be competing with this property. This is the oldest property, and will likely be impacted by the new construction in the area that may take away tenants.

Option 2: The second property is currently under construction, and is being sold because the developer has run out of money, and is unable to finish the project. However, it is likely that your firm could complete the building at a favorable per-unit cost. The market area is close to equilibrium, but with some excess supply, and the completion of this property would add even more. However, it would be a new building – something that is often attractive to potential tenants.

Option 3: The third property currently has a relatively high vacancy rate. However, the market area has become an increasingly desirable area to live and demand is expected to grow. There is also little threat of new competition here because there are no sites available to build additional apartment complexes. Given these vacancy considerations, which property would you choose? Are there other investment factors that may be impacted by these considerations?
