I have a few questions regarding the contract closeout process, especially with regards to common practices I see. 1) Why releases of claims included in modifications to deobligate excess funds? I am not finding a basis for this practice in regulation, and, IMO, it's far easier to just let the contractor submit a claim, should they deem such action necessary. 2) Would you consider a unilateral modification in order to remove all excess funds for contract closeout? If so, what authority would you cite on the SF 30? 3) I cannot locate guidance for how to properly use Block 5 on the DD 1594 - Contract Completion Statement. Under what circumstance will it be authorized to close a contract out with excess funds remaining? What about the checkbox "In Process"?
