What happens when a CMBS loan defaults at maturity — extension or modification?

When a CMBS loan fails to refinance at balloon, it becomes a 'maturity default' and transfers to the special servicer. The servicer's workout toolkit:

1. Short-term extension: commonly 6-24 months, sometimes with an extension fee and required equity injection. Market standard is a 12-month extension while the sponsor shops a refinance or sale.
2. Loan modification: permanent changes — extended amortization, rate reduction, partial debt forgiveness, or A/B note split (senior performing A, subordinate accrual B). Modifications are formally governed by the Pooling and Servicing Agreement (PSA) and trigger realized-loss accounting for the trust.
3. Discounted payoff (DPO): borrower pays a discount to loan balance to exit; loss is recognized immediately.
4. Deed-in-lieu or foreclosure: property taken into REO (real estate owned), servicer markets and sells it.

Investor view depends on tranche position:

- Senior tranches prefer quick resolution even at a loss because it reduces future interest-shortfall risk.
- Subordinate tranches prefer extension — the property may recover, saving their equity.
- The special servicer typically favors the controlling class (B-piece) view, which is often extension.

Modern PSAs constrain servicer discretion via 'servicer standard' and 'maximum recovery' tests to prevent conflicts of interest. The 2020-2023 office market stress produced a wave of extensions and modifications; the cumulative impact on B-piece IRRs is still being measured.

For FRM: extensions delay realized losses; modifications crystallize them. Track appraisal reduction amount (ARA) to estimate eventual loss.
