Give two examples of industries in which joint costs are found. For each example, what are the individual products at the split off point?

$$Managers must decide whether a product should be sold at splitoff or processed further. The sales value at split off method of joint$-$cost allocation is the best method for generating the information managers need for this decision.$$ Do you agree? Explain.

$$Why might managers seeking a monthly bonus based on attaining a target operating income prefer the sales method of accounting for byproducts rather than the production method?
