Management’s Discussion and Analysis of Financial Condition and Results of Operations - (continued)
(Amounts in Millions, Except Per Share Amounts)
adjustments to contingent acquisition obligations, as compared to the prior year, as well as lower production expenses related to pass-through costs, which are also reflected in revenue.
Operating income increased during the first half of 2017 when compared to the first half of 2016, as a result of a decrease in office and general expenses of $14.0 and a decrease in salaries and related expenses of $9.3, partially offset by a decrease in revenue of $16.4, as discussed above. The increase in operating income was primarily driven by factors similar to those noted above for the second quarter of 2017.
CORPORATE AND OTHER
Certain corporate and other charges are reported as separate line items within total segment operating income (loss) and include corporate office expenses, as well as shared service center and certain other centrally managed expenses that are not fully allocated to operating divisions. Salaries and related expenses include salaries, long-term incentives, annual bonuses and other miscellaneous benefits for corporate office employees. Office and general expenses primarily include professional fees related to internal control compliance, financial statement audits and legal, information technology and other consulting services that are engaged and managed through the corporate office. Office and general expenses also include rental expense and depreciation of leasehold improvements for properties occupied by corporate office employees. A portion of centrally managed expenses are allocated to operating divisions based on a formula that uses the planned revenues of each of the operating units. Amounts allocated also include specific charges for information technology-related projects, which are allocated based on utilization.
Corporate and other expenses decreased during the second quarter of 2017 by $2.1 to $21.8 compared to the second quarter of 2016. During the first half of 2017, corporate and other expenses decreased by $3.8 to $59.3 compared to the first half of 2016.

Net cash used in operating activities during the first half of 2017 was $153.1, which was an improvement of $400.7 as compared to the first half of 2016 driven by lower use of cash in working capital. Working capital in the first half of 2017 benefited from the spending patterns of our clients compared to a year ago. Due to the seasonality of our business, we typically use cash from working capital in the first half of a year and generate cash from working capital in the second half of a year, with the largest impacts generally in the first and fourth quarters. The working capital use in the first half of 2017 was primarily attributable to our media businesses.
The timing of media buying on behalf of our clients across various countries affects our working capital and operating cash flow and can be volatile. In most of our businesses, our agencies enter into commitments to pay production and media costs on behalf of clients. To the extent possible, we pay production and media charges after we have received funds from our clients. The amounts involved substantially exceed our revenues and primarily affect the level of accounts receivable, expenditures billable to clients, accounts payable and accrued liabilities. Our assets include both cash received and accounts receivable from clients for these pass-through arrangements, while our liabilities include amounts owed on behalf of clients to media and production suppliers.
