Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying unaudited consolidated financial statements of Kelly Services, Inc. (the “Company,” “Kelly,” “we” or “us”) have been prepared in accordance with Rule 10-01 of Regulation S-X and do not include all the information and notes required by generally accepted accounting principles (“GAAP”) for complete financial statements. In the opinion of management, all adjustments, including normal recurring adjustments, necessary for a fair statement of the results of the interim periods, have been made. The results of operations for such interim periods are not necessarily indicative of results of operations for a full year. The unaudited consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto for the fiscal year ended December 31, 2017, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 20, 2018 (the 2017 consolidated financial statements). The Company’s third fiscal quarter ended on September 30, 2018 (2018) and October 1, 2017 (2017), each of which contained 13 weeks. The corresponding September year to date periods for 2018 and 2017 each contained 39 weeks. Selling, general and administrative (“SG&A”) expenses for the 13 and 39 weeks ended October 1, 2017 include a $2.8 million and $1.4 million, respectively, benefit resulting from an out-of-period correction of expenses that were overstated in prior periods. The out-of-period errors and adjustments did not have a material effect on any of the periods impacted. Certain reclassifications have been made to the prior years’ consolidated financial statements to conform to the current year’s presentation.
