"This Sidebar examines possible effects that a government shutdown could have on new and existing federal contracts. It does not address particular agencies or specific contracts. While certain agencies have issued contingency plans that provide guidance about how the funding lapse affects their contracts and procurement programs, the detail of such guidance varies by agency and contract. In some instances, agencies might have provided only general guidance applicable to all contractors that might not clearly address all relevant issues associated with individual contracts. In other instances, agency contracting officers might have provided individualized guidance or formally exercised rights under specific contracts in advance of a funding lapse. However, given the uncertainties surrounding this partial shutdown, contracting officers might not have fully addressed every individual contract in advance of the funding lapse. As a result, contracting officers may need to modify contracts or take other actions to address the impact the shutdown had on individual contracts after funding is approved."
