Call protection limits a borrower’s ability to prepay or “call” debt before maturity — protecting lenders from losing expected interest income.

How it works

In corporate bonds and many private credit facilities, call provisions let the issuer redeem debt early — often after a non-call period. Call protection is the window where early redemption is forbidden or penalized.

Common structures:

• Non-call period: No prepayment for the first 12–24 months
• Call premium: Declining penalty (e.g., 3% in year three, 2% in year four) if debt is retired early
• Make-whole provision: Borrower pays present value of remaining interest to compensate lenders fully

Venture debt agreements may include prepayment fees or minimum interest guarantees that function similarly. Founders celebrating a big equity round should model the cost of retiring debt early, not just the headline interest rate.

In LBO structures, call protection interacts with cash sweep provisions — lenders may be protected from early payoff in some periods while still capturing excess cash through sweeps rather than voluntary prepayment.

Why it matters

• Founders: Refinancing after growth can trigger unexpected fees. Negotiate call protection length and premiums upfront if you expect rapid valuation step-ups.
• Investors: Debt overhang with tight call protection can complicate M&A or recapitalizations — acquirers factor breakage costs into deal pricing.

Common mistake

Assuming you can pay off venture debt anytime without penalty. Read the prepayment section alongside covenants and warrant coverage.
