LPP S.A. uses a joint process to produce products CC, DD, EE, and FF. Each product may be sold at its split-off point or processed further. Joint processing costs for a single batch of joint products are $110,000. Other relevant data are as follows:

Product	Sales Value At Split-Off	Additional Costs of Processing	Sales Value of Final Product
CC	$26,000	$31,000	$70,000
DD	38,000	25,000	63,000
EE	32,000	27,000	65,000
FF	18,000	22,000	42,000

Requirements:

1. Calculate the effect on profits of processing Product CC further beyond the split-off point.
2. Determine the profitability of further processing Product DD.
3. Allocate joint costs using the net realizable value method.
4. Prepare a production cost report for LPP S.A.
