Item 7.01.  Regulation FD Disclosure

On April 18, 2018, R.R. Donnelley & Sons Company (the “Company”) introduced new financial reporting segments following a change to its management reporting structure. Effective with the first quarter of 2018, the Company will report its results under new segments entitled Marketing Solutions and Business Services. Certain unallocated costs reported in the Company’s Corporate segment will not be impacted by the new structure.

To facilitate investors’ understanding of the new reporting segments, the Company is furnishing this Current Report on Form 8-K to provide the unaudited historical quarterly and full year financial information recast to reflect the new reporting segments. The recast financial information includes certain non-GAAP financial measures reconciled to the GAAP measures and is being furnished as Exhibit 99.1 hereto.

During the first quarter of 2018, the Company adopted ASU No. 2017-07 “Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which changes the presentation of net periodic pension cost and net periodic postretirement benefit cost within the Statement of Operations. The amendment requires the bifurcation of net benefit cost, with the service cost component to be presented in income from operations, while the other components are reported separately outside of income from operations. The accompanying recast financial information reflects the retrospective adoption of the revised guidance.

The information in this Item 7.01 and the Exhibit attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section, nor shall it be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such filing.
