What information is needed? Provided all information...

Also, based on this I have already mentioned a solution for part c , kindly verify and let me know

a. What assets and liabilities of unconsolidated affiliates are omitted from Cummins balance sheet as a result of the equity method of accounting for those investments?

b. Do the liabilities of the unconsolidated affiliates affect Cummins directly? Explain

c. How does the equity method impact a company's ROE and its RNOA components (net operating asset turnover and net operating profit margin)?

for part c-->

Note: My opinion is :

I guess the ROE is unaffected and for the RNOA components, ( Net Operating Asset Turnover-NOAT) ---> Sales/Average Net operating Assets

Since Investees sales are excluded from the NOAT numerator, and net operating assets in excess of the investment balance are excluded from the denominator. This means the impact on NOAT is indeterminate and the Net Operating Proft Margin value is overstated

Please verify and let me know if understanding is correct
