Berkshire Hathaway (NYSE:BRK.B) is a unique company. You have a property-casualty insurance giant owning many businesses directly through insurance subsidiaries, including huge businesses like a Class 1 Railroad - BNSF.
Yes, National Indemnity owns BNSF in entire, and many other businesses as well. I thought the pre-crisis organization chart of AIG was complex - because of the many industries that it covers, BRK is far more complex. In the 2012 statutory statements, it runs for 22 pages. Let me list the top-level subsidiaries, and any significant lower level subsidiaries they own.

BRK is huge, and Buffett prefers owning whole companies to portions of companies, because then the entire free cash flow is available to him, not just the dividends.
The first question to answer is why does Buffett have some industrial companies inside his insurers, and some not? That has to do with risk-based capital. P&C insurers have to put up capital equal to 22.5% on equity of affiliated insurers, 15% on non-affiliated common stocks and 20% on Schedule BA investments that are similar to stocks. These are more liberal than the standards for life companies, which have a 30% charge on stocks. (Which doesn't make sense, because life insurers have longer balance sheets, and have a better ability to hold equities, but I digress.)
Even if they have to put up capital to own the companies, BRK has a negative cost of capital inside its insurers, as they make underwriting profits. What a business - make money on insurance, and on businesses owned by the insurance subsidiary.
One more thing about BRK's insurance subsidiaries - in general, because they have so much asset risk, they don't write as much insurance as other companies of their size would.
I will write part 2 soon, regarding the one anomaly I found going through BRK's statutory books, the Harney Investment Trust. Till then.
Full disclosure: Long (BRK.B) for clients and myself.
