I think this article is a little propagandaish for hn. It really feels like a giant misrepresentation of the truth.<p>Berkshire was not hiding the fact they owned these derivatives. Buffett has talked about thm many times and defends purchasing this specific set of derivatives as having been "mispriced at inception" which I think is the most basic plan of all investing, right. Buy low, sell high.<p>As to the lobbying of congress, I would do the same thing, and you would too. When the derivitives contracts were drawn up Berkshire offered both a collatoralized and uncollatoralized option for the contract. The other parties would have paid a higher premium to Berkshire for the collatoralized contract, so they selected to forgo collatoral. Now, after the fact congress is going to step in and demand the contract have collatoral?<p>If I borrow money unsecured, I'm going to pay a higher interest rate. It would be extremely crappy to come in half way through the loan and demand that I put my house up ad collatoral. Now I have all the risk, and didn't even get to benefit from the lower I intrest rate at inception.<p>THAT'S what he's lobbying against.<p>And ontop of all of that, Buffett has said that if congress does include retroactive collatoralization, he will just pay it and his business will still be fine. So where's the fall from grace?<p><a href="http://www.bloomberg.com/apps/news?pid=10000103&sid=aZcI_iSCOUWM" rel="nofollow">http://www.bloomberg.com/apps/news?pid=10000103&sid=aZcI...</a>
