Is it possible to roll the left over ceiling down from other options to cover the current option?
This response is based on the information provided. We suggest you discuss with your contracting team, program manager, financial manager and/or legal department as appropriate.
You will need to check your original acquisition strategy, as amended, to see what the intent of the team was when contemplating the acquisition. If the strategy explicitly set an annual or per option limit, then that is what you would manage to unless you amend the acquisition strategy/plan. If the plan is silent, we believe you may transfer/roll forward funds not expended assuming those funds have not expired.
