(appendix) Joint costs: manufacturer Cygnet Sawmill manufactures two timber products from a joint milling process. The M0 products are mine support braces M53) and lengths of unseasoned commercial building timber (CBT). A standard production run Incurs joint costs of 950000 and results in 60000 units of M53 and 90000 lengths of CBT. Each MSB sells for $5, and each length of CBT sells for $10. Required: 1. Calculate the amount ofjoint cost allocated to the CBT on a physical units basis. 2. Calculate the amount ofjoint cost allocated to the M535 on a relative sales value basis. 3. Assume the CBT is not marketable at split-off but must be further planed and sized at a cost of $1 000000 per production run. During this process. 10000 lengths are unavoidably lost: these spoiled units have no value. The remaining lengths of CBT are saleable at $25 per unit. The M535. although saleable immediately at the split-oi? point. are coated with a sticky preservative that costs $250000 per production run. The MSBs are then sold for $12.50 each. Using the net realisable value method, calculate the cost assigned to each length of GET. 4. If Cygnet Sawmill chooses not to process the MSBs beyond the split-off point. by how much would the contribution from the joint milling process increase or decrease? 5. Did you use thejoint cost allocation results in answering requirement 4? lfso, how did you use them? Why did you use or not use the allocation results
