[2] The company was created by the merger of First Boston Corporation and Credit Suisse Group in 1988 and was active in investment banking, capital markets and financial services.

In 2022, as part of a major restructuring, Credit Suisse began the process of spinning out the investment bank into an independent company and revived the brand.

A Nevada judge issued a cease and desist order to stop Barclays from taking American owned assets and offering them to international buyers from Iran, Iraq, Syria, Egypt, and North Korea.

In 2000, Credit Suisse First Boston spent $13 billion to buy Donaldson, Lufkin & Jenrette (also known as DLJ) as stock markets were peaking.

In order to keep top bankers, CSFB handed them three-year guaranteed contracts, swelling costs relative to revenue and leading to two years of losses at the investment bank.

[9] After the collapse in technology shares in 2001, Credit Suisse replaced CSFB’s CEO Allen Wheat with Morgan Stanley's John Mack, who was charged with turning around the investment bank.

Mack fired 10,000 employees, or one-third of CSFB's workforce, although many former DLJ bankers continued to collect guaranteed pay long after they were gone.

The probe led to the conviction of Frank Quattrone in 2004, who was found guilty of urging employees to destroy documents after he learned about the investigation.

[14] Mr. Justice Michael Moriarty said that while the volume of material produced by the Revenue Commissioners in an application to investigate tax-evading offshore bank accounts may have been "somewhat excessive", it related to matters which had been discussed in all media, including "the conduct of banking institutions both in Ireland and elsewhere, as exemplified by the Credit Suisse First Boston sequence of advertisements in the Irish Times".
