S&P's downgrade of U.S. credit rating means a downgrade of U.S. based business credit ratings? Insane.

[Gutenberg]

I got this notice from my insurance company. I don't get S&P's rationale, which is, essentially, that since it downgraded the nation's credit rating, it also downgrades the credit ratings of businesses that are based in the country. Last I checked, businesses in this country don't have to check with Congress before paying the bills.
