ペン・セントラル鉄道
Another financial crisis for the firm occurred in 1970, when the Penn Central Transportation Company went bankrupt with over $80 million in commercial paper outstanding, most of it issued through Goldman Sachs. The bankruptcy was large, and the resulting lawsuits, notably by the SEC, threatened the partnership capital, life, and reputation of the firm. It was this bankruptcy that resulted in credit ratings for every issuer of commercial paper today by several credit rating services.
