Moody's affirmed Jane Street Group LLC's issuer rating and senior secured first-lien term loan rating at Ba3.

The rating agency also assigned a Ba3 rating to Jane Street's $2.0 billion seven-year senior secured first-lien term loan. According to the Moody's report, Jane Street plans to use the net proceeds from the offering to refinance its existing $1.5 billion term loan, to support its operations and trading capital, and for general corporate purposes.

The outlook on the ratings is stable.

Moody's said the affirmation reflects the company's "highly profitable" credit profile and its "strong level" of retained capital. However, the rating agency said that though Jane Street has an effective risk management framework in place, the company may need to evolve it at a faster pace along with its control processes, given the firm's growth trajectory.
