About APL


APL is a UARC, what does that mean?
  • As a University Affiliated Research Center (UARC), APL was established to provide or maintain essential engineering, research, and/or development capabilities through a long-term, strategic relationship with DoD. APL has core competencies identified that must be provided in support of its mission to support DoD.
  • APL must adhere to specific requirements in the way that we conduct our business activities
  • These requirements are detailed in a UARC Management Plan which ensures that we remain consistent with public policy
Accounting, Estimating, Property and Purchasing Differences
  • APL is audited by DCAA as a commercial entity and is held to different standards than the university. These audits allow APL to maintain its business system approvals (accounting, estimating, property, and purchasing).
  • In order to maintain the aforementioned business system approvals, APL requires JHU and other subcontractors to provide more detailed budget justifications and back up than is customary at a university. Our sponsors, DCAA and contracts clauses require this level of detailed information. This information is used to conduct a cost/price analysis as well as technical evaluations.
  • DCAA auditors sit on-site at APL and can come to us at any time and request information.
  • APL operates under Commercial Cost Principles (per FAR 31.2) and is not subject to the Uniform Guidance (UG) Cost Principles (Subpart E). Instead of a Negotiated Indirect Costs Rate Agreement (NICRA), APL utilizes its current Forward Pricing Rates (FPR) to develop proposals. It's important for JHU to be aware of this distinction when contracting under federal awards (or associated subawards/subcontracts) to help ensure that the appropriate terms and conditions are aligned with APL's requirements Additionally, all support provided by APL to JHU requires the submission of a proposal prepared in compliance with APL's Corporate Policy & Procedure.
