Business Combinations [Abstract]
Acquisitions and Disposition	Acquisitions and Disposition Acquisitions In the first quarter of 2020, Kelly Services USA ("KSU"), LLC, a wholly owned subsidiary of the Company, acquired Insight Workforce Solutions LLC and its affiliate, Insight EDU LLC (collectively, "Insight"), as detailed below. In the fourth quarter of 2020, KSU acquired Greenwood/Asher & Associates, LLC ("Greenwood/Asher"), as detailed below. Greenwood/Asher On November 18, 2020, KSU acquired 100% of the membership interests of Greenwood/Asher, a premier specialty education executive search firm in the U.S., for a purchase price of $3.5 million. Under terms of the purchase agreement, the purchase price was adjusted for cash held by Greenwood/Asher at the closing date and estimated working capital adjustments resulting in the Company paying cash of $5.2 million. The purchase price of the acquisition also included contingent consideration with an estimated fair value of $2.1 million related to an earnout payment in the event certain conditions are met per the terms of the agreement. The initial fair value of the earnout was established using a Black Scholes model and the liability is recorded in accounts payable and accrued liabilities and other noncurrent liabilities in the consolidated balance sheet (see Fair Value Measurements footnote). Subsequently, the earnout was revalued, resulting in a decrease to the liability of $0.4 million in the first quarter of 2021. The earnout is expected to be paid in 2022 and 2023 after each earnout year pursuant to the terms of the purchase agreement. The purchase price allocation for this acquisition is preliminary and could change. Goodwill generated from the acquisition was primarily attributable to the expected synergies from combining operations and expanding market potential, and was assigned to the Education reporting unit (see Goodwill footnote). The amount of goodwill expected to be deductible for tax purposes is approximately $0.9 million. Insight On January 14, 2020, Kelly Services USA, LLC acquired 100% of the membership interests of Insight, an educational staffing company in the U.S, for a purchase price of $34.5 million. Under terms of the purchase agreement, the purchase price was adjusted for cash held by Insight at the closing date and estimated working capital adjustments resulting in the Company paying cash of $38.1 million. The purchase price of the acquisition also included contingent consideration with an estimated fair value of $1.6 million related to an earnout payment in the event certain conditions are met per the terms of the agreement. The initial fair value of the earnout was established using a Monte Carlo simulation and the liability is recorded in accounts payable and accrued liabilities in the consolidated balance sheet (see Fair Value Measurements footnote). Subsequently, the earnout was revalued, resulting in a net increase to the liability of $0.1 million in 2020 and there were no material adjustments to the liability in the first quarter of 2021. In the second quarter of 2020, the Company paid a working capital adjustment of $0.1 million. As of year-end 2020, the purchase price allocation for this acquisition is final. Goodwill generated from the acquisition was primarily attributable to the expected synergies from combining operations and expanding market potential, and was assigned to the former Americas Staffing reporting unit. The goodwill related to this acquisition was included in the goodwill impairment charge taken in the first quarter of 2020. The goodwill impairment charge resulted from an interim goodwill impairment test triggered by declines in our common stock price as a result of negative market reaction to the COVID-19 crisis (see Goodwill footnote). The amount of goodwill expected to be deductible for tax purposes is approximately $18.6 million. Disposition On August 18, 2020, the Company sold its Brazil operations for a purchase price of $1.4 million. The Company received cash proceeds of $1.2 million, net of cash disposed. As a part of the transaction, the Company has agreed to indemnify the buyer for losses and costs incurred in connection with certain events or occurrences initiated within a six-year period after closing. The aggregate losses for which the Company will provide indemnification shall not exceed $8.8 million. Accordingly, the Company recorded an indemnification liability of $2.5 million at the time of disposition in other long-term liabilities in the consolidated balance sheet, which represented the fair value of the liability (see Fair Value Measurements footnote) and completely offset the gain on the sale.
