LIBOR transition is the industry-wide move away from LIBOR as the floating-rate index for loans, bonds, and swaps.

How it works

LIBOR was based on bank submissions; scandals and thin underlying markets led regulators to phase it out. US dollar contracts now commonly use SOFR (Secured Overnight Financing Rate), often with a credit spread adjustment for legacy conversions. Loan documents written before the transition include fallback language triggering when LIBOR became unavailable.

Venture debt facilities and subscription lines signed years ago may have been amended or converted during refinancing waves.

Why it matters

• Founders: A surprise rate index change affects interest expense and covenant calculations tied to floating rates. Ask your lender which benchmark governs today.
• Investors: Portfolio company debt service affects runway. LIBOR transition itself is mostly mechanical but exposes sloppy documentation if fallbacks were missing.

Credit agreements may include benchmark replacement language referencing SOFR plus a spread adjustment. Founders should confirm whether floors and caps on interest rates still apply after index change.

Hedging instruments tied to LIBOR needed amendment or termination during the transition — legacy deals without fallback language required legal patches.

Common mistake

Assuming LIBOR transition only affects big banks. Any floating-rate company debt or interest rate hedge could reference legacy language.

Practical takeaway

Review any outstanding credit agreement for the current benchmark and spread. Refinancing may be the cleanest path if legacy LIBOR language is ambiguous — do not assume automatic conversion without reading the fallback clause.
