Mitt Romney & Vulture Capitalism
First of all, Romney had cut all ties with Bain by August 2001, about 6 years prior to the GC acquisition (even earlier if you count his leave of absence for the Olympics starting in 1999). Citing his name here is nothing more than a baseless political smear.
Second of all, calling the Guitar Center acquisition "vulture capitalism" demonstrates a pretty serious lack of understanding of scenarios where that term is more applicable. This buyout was neither a "hostile takeover" (Guitar Center management approved the deal, as did shareholders), nor did it involve liquidation of assets. By all accounts, Bain wants the company to succeed.
This was a pretty straightforward public-to-private leveraged buyout (LBO) deal that just hasn't really panned out. At the time of the deal (mid-2007), everything looked good on paper. The resulting debt ratio needed to go private seemed very manageable ($2.1 billion to go private, vs. operating profits in the ~$70 million range). But the subsequent recession starting in 2008 hit Guitar Center's sales substantially, and now the company is worth considerably less than the $1.9 billion raised to purchase it, and its operating revenues struggle to service the purchase debt, not to mention operating debt.
That's a worst-case-scenario for the financial sponsor of an LBO (e.g., Bain), and certainly not what they wanted to happen. Bain was almost certainly hoping to have sold off Guitar Center Holdings at a profit by now, rather than struggling to keep it afloat. Many analysts have suggested that if it weren't for Bain's reputation being attached to Guitar Center Holdings, they wouldn't even be able to borrow any money right now to try to stay afloat.
This is just an example of the volatility involved with taking risks based on past performance. Here a group of investors (e.g., Bain) thought they could buy the company from public shareholders and turn it around for a nice profit, but they simply over-estimated the company's future potential (or under-estimated the risk, either way). Goldman Sachs, who floated the LBO loan, stands to take the biggest financial hit if the company defaults. They can hedge against taking a catastrophic loss by paying for a credit default swap insurance premium, which they almost certainly have already done. But collecting that policy would almost certainly not recoup their investment, so they would much rather see Guitar Center succeed too and see their loan repaid with interest.
The only people who want to see Guitar Center fail are those who have purchased credit default swaps against GC but have no capital at risk (pure speculators), and of course GC's competitors. Both Bain and Goldman-Sachs have a strong incentive to see GC succeed. Suggesting otherwise is simply ignorant.
