    Special terms

    Use K4 to reflect specialized payment structures such as deferrals or balloons. Populate start dates and amounts where required so downstream models can interpret performance correctly.

    Deferrals vs. hardship

    Distinguish between scheduled deferral programs and hardship accommodations. K4 covers structured scenarios (e.g., deferment start date), while narrative markers may be captured via special comment codes when appropriate.

    Balloon amounts

    Report the balloon amount when the contract defines one. Ensure the term duration and payment schedule align to avoid implying a nonexistent amortization.
