Alternative methods of joint costs allocation, product-mix decision.

Pacific Lumber processes lumber products for sale to lumber wholesalers. Its most popular line is oak products. Oak tree growers sell Pacific Lumber whole trees. These trees are jointly processed up to the split off point at which raw select oak, raw white oak, and raw knotty oak become separable products. Each of these raw products is then separately further processed by Pacific Lumber into finished products (select oak, white oak, and knotty oak) that are sold to lumber wholesalers. Data for August 2019 are:

a.Joint processing costs (including cost of oak trees) $300,000

b.Separable product at split off point

sRaw select oak30,000 board feet

sRaw white oak50,000 board feet

sRaw knotty oak 20,000 board feet

sFinal product produced

sSelect oak 25,000 board feet at $16 per board foot

sWhite oak 40,000 board feet at $9 per board foot

sKnotty oak15,000 board feet at $7 per board foot

c.Separable processing costs

Required

Allocate the joint costs to the three products and calculate the ending inventory values using:

a)Split off at Sales Value Method

b)Estimated net realizable value method (NRV)

c)Constant Gross Profit method

2)Prepare in good form a Gross Margin Statement for each method. Ending inventory for August 2019 was select oak (1,000 board feet), white oak (2,000 board feet), and knotty oak (500 board feet).

3)Is Pacific Lumber maximizing its total August 2019 operating income by fully processing each raw oak product into its finished product form? Show computations.
