FASB ASU 2011-09ⁱ requires additional quantitative and qualitative disclosures about an employer’s participation in a multiemployer defined benefit pension plan. One of the main characteristics of a multiemployer pension plan is that the assets contributed by one employer may be used to pay benefits to employees of other participating employers. In the past, the disclosures available to a user of an employer’s financial statements about multiemployer pension plans were limited to historic contributions. The FASB added the multiemployer plan project to its agenda in response to financial statement user concerns that companies participating in multiemployer plans are not required to provide the information users considered necessary to determine the company’s obligation to these often underfunded plans
