William Cohan, Bloomberg Columnist and former investment banker unloads on Mitt Romney with both barrels:

By bidding high early, Bain would win a coveted spot in the later rounds of the auction, when greater information about the company for sale is shared and the number of competitors is reduced. (A banker and his client generally allow only the potential buyers with the highest bids into the later rounds; after all, you can’t have an endless procession of Savile Row-suited businessmen traipsing through a manufacturing plant if you want to keep a possible sale under wraps.)

For buyers, the goal in these auctions is to be one of the few selected to inspect the company’s facilities and books on-site, in order to make a final and supposedly binding bid. Generally, the prospective buyer with the highest bid after the on-site due-diligence visit is selected by the client — in consultation with his or her banker — to negotiate a final agreement to buy the company.

This is the moment when Bain Capital would become especially crafty. In my experience — which I heard echoed often by my colleagues around Wall Street — Bain would seek to be the highest bidder at the end of the formal process in order to be the firm selected to negotiate alone with the seller, putting itself in the exclusive, competition-free zone. Then, when all other competitors had been essentially vanquished and the purchase contract was under negotiation, Bain would suddenly begin finding all sorts of warts, bruises and faults with the company being sold. Soon enough, that near-final Bain bid — the one that got the firm into its exclusive negotiating position — would begin to fall, often significantly.

Of course, some haggling over price is typical in any sale, and not everything represented by sellers and their bankers is found to be accurate under close examination. But Bain Capital took the art of negotiation over price into the scientific realm. Once the competitive dynamics had shifted definitively in its favor, the firm’s genuine views about what it was willing to pay — often far lower than first indicated — would be revealed.

And then there is the closing line:

I have no idea how Romney might behave in office. I do believe, however, that when he was running Bain Capital, his word was not his bond.

This guy has clearly been waiting for years to unload on Romney, and this take-down is truly a thing of beauty.
