What is the difference between Term Loan A, Term Loan B, and a revolving credit facility?

Term Loan A is usually bank-held, amortizing, and relationship-driven. Term Loan B is institutional, more bullet-like, higher spread, and common in leveraged finance. A revolving credit facility can be drawn and repaid for liquidity and working-capital needs. RCF is a liquidity backstop, not permanent acquisition debt in most cases.
