Cost Share/Match

Many funding agencies require cost sharing by the recipient institution. Cost sharing refers to the portion of the project or program cost that is not reimbursed by the sponsor. It may be required by the sponsor as a condition of the award (mandatory) or it may be offered by the California State University, Long Beach (University) in excess of mandatory cost sharing requirements (voluntary). Whether cost sharing is required by the sponsor or is offered by the University or Project Director voluntarily, once an award is made all cost sharing commitments are considered to be mandatory, and as such represent binding obligations of the University and California State University, Long Beach Research Foundation (Foundation).

Cost Sharing is defined as costs that are incurred to support a sponsored project that are not reimbursed by the sponsor. There are two types of cost sharing mandatory and voluntary.

Mandatory: Cost sharing refers to cost sharing that is required by a sponsored grant or contract in writing.

Voluntary: Cost sharing that is not explicitly required by such an agreement. Voluntary cost sharing is further divided into two categories committed and uncommitted.

  • Voluntary committed cost sharing: refers to cost sharing that is not explicitly required by the sponsor, but is committed to the sponsor by the recipient in the proposal and/or budget.
  • Voluntary uncommitted cost sharing: is defined as effort that is over and above that which is committed and budgeted for in a sponsored agreement.

Important: Cost Share/Match is not allowed unless stated as a requirement on the solicitation (proof from Sponsor is required) and approved by corresponding college and the AVP for Research. Please see CSULB Policy on Cost Share/Match Microsoft Word 2007 Document.

CSULB Requirement: PI must dedicate at least 1% or .01 months to the project budget otherwise proposal will bear voluntary committed cost sharing which is not allowed under CSULB policy unless approved by the AVP for Research.
