I am confused by your post, haha
All profits/losses, assets/liabilities and cash flows reported in a company's
consolidated accounts assume that the company owns 100% of all their subsidiaries. The company just adds everyone's numbers together. However, in reality they don't own 100% of their subsidiaries, so they do not share in 100% of their subsidiaries' profits. Thus, below all the accounting, the company minuses off this "minority interest", the part they do not own and control.
Please have a look at JC&C's 2012 annual report, for the year ending 31 Dec 2012. Reported profit after tax is USD 2,330.2m. Of this, profit attributable to shareholders of the company is USD 987.0m; to non-controlling interests, USD 1,343.2m. On pages 76-77 (note 9, earnings per share), JC&C lays out the calculation to get to USD 987.0m.
I cannot pretend to understand it very well, because I don't have an accounting background, but to put it simply, JC&C's 2012 profit would be USD 2,330.2m if they owned all of Astra, as laid out in their consolidated statement. But they don't, they own only 50.1% of it. So JC&C's actual 2012 profit is about half, USD 987.0m.
This can be verified by looking at
Astra's financial statement for the year ending 31 Dec 2012, which JC&C also makes available in their SGX announcements. They report a net income of IDR 19,421b. As the USD-IDR exchange rate was around 9,000-10,000 in the year 2012, this means a net income of around USD 2b. Logically, because JC&C owns half of Astra, and its non-Astra businesses are relatively small, JC&C will share half of Astra's profits i.e. around USD 1b. Not surprisingly, that's what we get in JC&C's statement.
