"Revenue" isn't a taxable item - earnings are. Net income is after tax, although, to add to your confusion, financial statement accrued net income (which is reported) is different from tax income. To oversimplify, companies keep two sets of books - the tax books and the financial accounting books.
So Harley's Net Income (after tax) was $200 million.
Buell might be consolidated (depends on control as well as ownership), or it might not be - and it might not be material, even if consolidated. There are many considerations.
If it's not consolidated, only "Equity in Income of Unconsolidated Subsidiary" would appear, with no real further description. Alternatively, if it's consolidated but small, they might just ignore it. You'd be surprised what the materiality threshold might be for different companies.
