One area of labor organization-related finances where financial transparency is currently lacking concerns “trusts in which a labor organization is interested.”[12] Examples of such trusts “include credit unions, strike funds, development or investment groups, training funds, apprenticeship programs, pension and welfare plans, building funds, and educational funds.”[13]

The Obama administration rescinded the reporting regulation before any trust reports were ever filed.[14] A state could partially fix this by mandating that its public sector unions file a disclosure report for trusts. Doing so would disclose one activity for which financial transparency is lacking.
