In order to issue a bond on the market, it is recommended that the company have a rating from a rating agency. If it does not yet have one, the bank examines the company's credit and, based on its sector, tells the company which rating agencies would be the most appropriate.
When a judge announces no bond, the defendant isn't eligible for release from county jail through bail as the judge has not set a bail amount. Instead, the arrested person has to remain in custody until the case concludes or a judge potentially sets bail at a later hearing.
Although the Eighth Amendment protects against excessive bail, there is not an absolute right to bail, as noted in The Bail Reform Act, 18 USC Chapter 207. Section 3142 of the Act denies bail to certain defendants pending trial, specifically denying bail to defendants likely to flee or pose a danger to society.
