Coworker Retirement and Other Compensation Benefits | Coworker Retirement and Other Compensation Benefits Profit Sharing Plan and Other Savings Plans The Company has a profit sharing plan that includes a salary reduction feature established under the Internal Revenue Code Section 401(k) covering substantially all coworkers in the US. In addition, coworkers outside the US participate in other savings plans. Company contributions to the profit sharing and other savings plans are made in cash and determined at the discretion of the Board of Directors. For the years ended December 31, 2017, 2016 and 2015, the amounts expensed for these plans were $20 million, $23 million and $20 million, respectively. Coworker Stock Purchase Plan The Company has a Coworker Stock Purchase Plan (the “CSPP”) that provides the opportunity for eligible coworkers to acquire shares of the Company’s common stock at a 5% discount from the closing market price on the final day of the offering period. There is no compensation expense associated with the CSPP. Restricted Debt Unit Plan On March 10, 2010, the Company established the Restricted Debt Unit Plan (the “RDU Plan”), an unfunded nonqualified deferred compensation plan. Compensation expense related to the RDU Plan was $2 million, $2 million and $5 million for the years ended December 31, 2017, 2016 and 2015, respectively. On September 15, 2017, the Company settled the RDU Plan. The total payment made on September 15, 2017 was $31 million, which settled the obligation in full.

- Definition The entire disclosure for compensation costs, including compensated absences accruals, compensated absences liability, deferred compensation arrangements and income statement compensation items. Deferred compensation arrangements may include a description of an arrangement with an individual employee, which is generally an employment contract between the entity and a selected officer or key employee containing a promise by the employer to pay certain amounts at designated future dates, usually including a period after retirement, upon compliance with stipulated requirements. This type of arrangement is distinguished from broader based employee benefit plans as it is usually tailored to the employee. Disclosure also typically includes the amount of related compensation expense recognized during the reporting period, the number of shares (units) issued during the period under such arrangements, and the carrying amount as of the balance sheet date of the related liability. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 710 -URI http://asc.fasb.org/topic&trid=2127225 + Details
