"I am pleased to report record second quarter adjusted earnings of $1.58 per share, 7 percent higher than the prior year and 8 percent lower than the prior quarter. Segment income margin was 22 percent, 340 basis points higher than the prior year on higher margin in Materials Solutions and consistent margin in the Acetyl Chain along with productivity initiatives. Segment income margin declined by 210 basis points sequentially as higher margin in Materials Solutions was offset by lower margin in the Acetyl Chain due to higher raw material costs. Adjusted free cash flow was also a second quarter record at $176 million on strong earnings and working capital management," said Mark Rohr, chairman and chief executive officer.

"We continue to align along two complementary value drivers - Materials Solutions and the Acetyl Chain - in order to maximize value creation across the company. During the quarter, we appointed Scott Sutton as President of Materials Solutions and Pat Quarles as President of the Acetyl Chain. We believe this core alignment under these two proven leaders will drive clarity and focus in our operating and commercial model yielding value to our employees, customers and shareholders," said Rohr.

Second Quarter Business Segment Overview

Materials Solutions

Core income in Materials Solutions was $207 million on net sales of $595 million. Core income margin was 34.8%, up 520 basis points year-over-year and 40 basis points sequentially.

Advanced Engineered Materials

In the second quarter, Advanced Engineered Materials generated segment income of $102 million on net sales of $346 million. Segment income margin was 29.5 percent, 530 basis points higher than the prior year and 80 basis points lower than the previous quarter. Earnings in the base engineered materials business, excluding affiliates, were a record at $71 million and mostly offset $12 million lower sequential earnings from affiliates primarily driven by lower MTBE pricing. Volume grew 2 percent sequentially, mainly driven by industrial applications globally, consumer applications in Asia and electronics applications in Europe. The business continues to grow faster than auto industry build rates, increasing content per vehicle sequentially, primarily in the Asia region. Price was consistent sequentially. Success in this business continues to be driven by our ability to work closely with customers and develop innovative solutions that leverage our broad and differentiated polymer portfolio. During the quarter, the business completed and launched over 200 projects, including both new products and new applications.

Consumer Specialties

Consumer Specialties' second quarter segment income increased $13 million sequentially to $105 million on $249 million of net sales. Segment income margin was 42.2 percent, a 520 basis point increase from the prior year quarter and 170 basis points higher than the prior quarter. Volume increased 11 percent sequentially due to less sequential customer destocking activity in the quarter. Price declined 1 percent on geographic product mix and a legacy flake contract. Dividends from the cellulose derivatives ventures were $26 million.

3

Acetyl Chain

Core income in the Acetyl Chain was $137 million on net sales of $911 million. Core income margin was 15.0 percent, consistent with the prior year and 340 basis points below the prior quarter. Lower sequential margin was driven by significantly higher ethylene costs due to temporarily tight industry conditions in Europe and Asia as well as sequential softness in demand in China. Acetyl Chain volume increased 2 percent sequentially, mainly due to 6 percent volume growth in emulsion polymers on normal seasonal patterns in paints and coatings in Europe and Asia which helped offset lower demand in China for acetic acid and its derivatives. Price declined 1 percent sequentially mainly due to lower pricing in emulsion polymers driven by lower raw material costs, primarily VAM in Europe. The ability to deliver consistent margin in the Acetyl Chain on a year-over-year basis reflects the core's unique commercial flexibility to derive value across the entire acetyl industry chain and respond to prevailing industry conditions.

Cash Flow

The company generated operating cash flow of $283 million and adjusted free cash flow of $176 million in the second quarter, which were both second quarter records, driven by strong earnings and disciplined working capital management. Net capital expenditures were $90 million in the quarter. Cash on hand increased $137 million from the prior quarter to $988 million. The company ended the quarter with the lowest net debt in its history at $1.7 billion, $126 million lower than at March 31, 2015.

Outlook

"As we look to the remainder of 2015, we are confident in our ability to drive unique value in both of our cores despite year-over-year currency headwinds and the recent stress in the global macroeconomic environment, primarily due to the recent uncertainty in China. Our focus on execution and productivity, as well as our agility to match market needs, allows us to increase our 2015 adjusted earnings outlook range to $5.70 to $6.00 per share," said Rohr.

The company's earnings presentation and prepared remarks related to the second quarter results will be posted on its website at www.celanese.com under Investor Relations/Events and Presentations after market close on July 16, 2015. Information previously included in supplemental tables to our press release is now included in a separate Non-US GAAP Financial Measures and Supplemental Information document posted on our website.

Non-GAAP Financial Measures

Use of Non-US GAAP Financial Information

This release uses the following non-US GAAP measures: adjusted EBIT, operating EBITDA, adjusted earnings per share, adjusted free cash flow and net debt. These measures are not recognized in accordance with US GAAP and should not be viewed as an alternative to US GAAP measures of performance. The most directly comparable financial measure presented in accordance with US GAAP in our consolidated financial statements for adjusted EBIT and operating EBITDA is net earnings (loss); for adjusted earnings per share is earnings (loss) from continuing operations per common share-diluted; for adjusted free cash flow is cash flow from operations; and for net debt is total debt.

Definitions of Non-US GAAP Financial Measures

• Adjusted EBIT is defined by the Company as net earnings (loss) less interest income plus loss (earnings) from discontinued operations, interest expense and taxes, and further adjusted for certain items and amounts attributable to noncontrolling interests ("NCI"). Adjusted EBIT by business segment may also be referred to by management as segment income. Adjusted EBIT by core may also be referred to by management as core income.

• Operating EBITDA is defined by the Company as net earnings (loss) less interest income plus loss (earnings) from discontinued operations, interest expense, taxes and depreciation and amortization, and further adjusted for certain items and amounts attributable to NCI.Operating EBITDA is equal to adjusted EBIT plus depreciation and amortization.

• Adjusted earnings per share is defined by the Company as earnings (loss) from continuing operations, adjusted for income tax (provision) benefit, certain items, refinancing and related expenses and amounts attributable to NCI, divided by the number of basic common shares, convertible preferred shares and dilutive restricted stock units and stock options calculated using the treasury method.

Note: The income tax rate used for adjusted earnings per share approximates the midpoint in a range of forecasted tax rates for the year. This range may include certain partial or full-year forecasted tax opportunities, where applicable, and specifically excludes changes in uncertain tax positions, discrete items and other material items adjusted out of our GAAP earnings for adjusted earnings per share purposes, and changes in management's assessments regarding the ability to realize deferred tax assets. We also reflect the impact of foreign tax credits when utilized for the adjusted earnings per share tax rate. We analyze this rate quarterly and adjust if there is a material change in the range of forecasted tax rates; an updated forecast would not necessarily result in a change to our tax rate used for adjusted earnings per share. The adjusted tax rate is an estimate and may differ from the actual tax rate used for GAAP reporting in any given reporting period. It is not practical to reconcile our prospective adjusted tax rate to the actual GAAP tax rate in any given future period.

• Adjusted free cash flow is defined by the Company as cash flow from operations less other productive asset purchases, operating cash flow from discontinued operations and certain cash flow adjustments, including amounts attributable to NCI and capital contributions from outside stockholders of the Company's consolidated ventures.

• Net debt is defined by the Company as total debt less cash and cash equivalents, adjusted for amounts attributable to NCI.

Exhibit 99.2

Non-US GAAP Financial Measures and Supplemental Information

July 16, 2015

In this document, the terms "Company," "we" and "our" refer to Celanese Corporation and its subsidiaries on a consolidated basis.

Purpose

The purpose of this document is to provide information of interest to investors, analysts and other parties including supplemental financial information and reconciliations and other information concerning our use of non-US GAAP financial measures. This document is updated quarterly.

Presentation

This document presents the Company’s business segments in two subtotals, the Acetyl Chain and Materials Solutions, based on similarities among customers, business models and technical processes. The Acetyl Chain includes the Company’s Acetyl Intermediates segment and the Industrial Specialties segment. Materials Solutions includes the Company’s Advanced Engineered Materials segment and the Consumer Specialties segment. For comparative purposes, the historical financial information included herein has been presented to reflect the Acetyl Chain and Materials Solutions subtotals. There has been no change to the composition of the Company’s business segments.

Use of Non-US GAAP Financial Measures

From time to time, management may publicly disclose certain numerical "non-GAAP financial measures" in the course of our earnings releases, financial presentations, earnings conference calls, investor and analyst meetings and otherwise. For these purposes, the Securities and Exchange Commission ("SEC") defines a "non-GAAP financial measure" as a numerical measure of historical or future financial performance, financial position, or cash flows that excludes amounts, or is subject to adjustments that effectively exclude amounts, included in the most directly comparable measure calculated and presented in accordance with US GAAP, and vice versa for measures that include amounts, or are subject to adjustments that effectively include amounts, that are excluded from the most directly comparable US GAAP measure so calculated and presented. For these purposes, "GAAP" refers to generally accepted accounting principles in the United States.

Non-GAAP financial measures disclosed by management are provided as additional information to investors, analysts and other parties as the Company believes them to be important supplemental measures for assessing our financial and operating results and as a means to evaluate period-to-period comparisons. These non-GAAP financial measures should be viewed as supplemental to, and should not be considered in isolation or as alternatives to, net earnings (loss), operating profit (loss), cash flow from operating activities, earnings per share or any other US GAAP financial measure. The method of calculation of the non-GAAP financial measures used herein may be different from other companies' methods for calculating measures with the same or similar titles. Investors, analysts and other parties should understand how another company calculates such non-GAAP financial measures before comparing the other company's non-GAAP financial measures to any of our own. These non-GAAP financial measures may not be indicative of the historical operating results of the Company nor are they intended to be predictive or projections of future results.

Pursuant to the requirements of SEC Regulation G, whenever we refer to a non-GAAP financial measure, we will also present on the Investor Relations/Financial Information/Non-GAAP Financial Measures page of our website, www.celanese.com, in this document, in the presentation itself or on a Form 8-K in connection with the presentation, to the extent practicable, the most directly comparable financial measure calculated and presented in accordance with GAAP, along with a reconciliation of the differences between the non-GAAP financial measure we reference and such comparable GAAP financial measure. This supplemental financial disclosure should be considered within the context of our complete audited financial results for the given period, which are available on the Investor Relations/Financial Information/SEC Filings page of our website, www.celanese.com.

This document includes definitions and reconciliations of non-GAAP financial measures used from time to time by the Company.

This document provides information about the following non-GAAP measures: adjusted EBIT, operating EBITDA, adjusted earnings per share, net debt, adjusted free cash flow and return on capital employed. The most directly comparable financial measure presented in accordance with US GAAP in our consolidated financial statements for adjusted EBIT and operating EBITDA is net earnings (loss); for adjusted earnings per share is earnings (loss)

1

from continuing operations per common share-diluted; for net debt is total debt; and for adjusted free cash flow is cash flow from operations. We do not believe that there is a directly comparable financial measure calculated and presented in accordance with GAAP for return on capital employed.

Definitions

• Adjusted EBIT is defined by the Company as net earnings (loss) less interest income plus loss (earnings) from discontinued operations, interest expense and taxes, and further adjusted for certain items and amounts attributable to noncontrolling interests ("NCI"). We believe that adjusted EBIT provides transparent and useful information to management, investors, analysts and other parties in evaluating and assessing our core operating results from period-to-period after removing the impact of unusual, non-operational or restructuring-related activities that affect comparability. Our management recognizes that adjusted EBIT has inherent limitations because of the excluded items. Adjusted EBIT is one of the measures management uses for planning and budgeting, monitoring and evaluating financial and operating results and as a performance metric in the Company's incentive compensation plan. We may provide guidance on adjusted EBIT but are unable to reconcile forecasted adjusted EBIT to a US GAAP financial measure without unreasonable effort because a forecast of certain items is not practical. Adjusted EBIT by business segment may also be referred to by management as segment income. Adjusted EBIT by core may also be referred to by management as core income.

• Operating EBITDA is defined by the Company as net earnings (loss) less interest income plus loss (earnings) from discontinued operations, interest expense, taxes and depreciation and amortization, and further adjusted for certain items and amounts attributable to NCI.Operating EBITDA is equal to adjusted EBIT plus depreciation and amortization, and has the same uses and limitations as adjusted EBIT described above.

• Adjusted earnings per share is defined by the Company as earnings (loss) from continuing operations, adjusted for income tax (provision) benefit, certain items, refinancing and related expenses and amounts attributable to NCI, divided by the number of basic common shares, convertible preferred shares and dilutive restricted stock units and stock options calculated using the treasury method. We believe that adjusted earnings per share provides transparent and useful information to management, investors, analysts and other parties in evaluating and assessing our core operating results from period-to-period after removing the impact of unusual, non-operational or restructuring-related activities that affect comparability. We may provide guidance on adjusted earnings per share but are unable to reconcile forecasted adjusted earnings per share to a GAAP financial measure without unreasonable effort because a forecast of certain items is not practical.

Note: The income tax rate used for adjusted earnings per share approximates the midpoint in a range of forecasted tax rates for the year. This range may include certain partial or full-year forecasted tax opportunities, where applicable, and specifically excludes changes in uncertain tax positions, discrete items and other material items adjusted out of our GAAP earnings for adjusted earnings per share purposes, and changes in management's assessments regarding the ability to realize deferred tax assets. We also reflect the impact of foreign tax credits when utilized for the adjusted earnings per share tax rate. We analyze this rate quarterly and adjust if there is a material change in the range of forecasted tax rates; an updated forecast would not necessarily result in a change to our tax rate used for adjusted earnings per share. The adjusted tax rate is an estimate and may differ from the actual tax rate used for GAAP reporting in any given reporting period. It is not practical to reconcile our prospective adjusted tax rate to the actual GAAP tax rate in any given future period.

• Adjusted free cash flow is defined by the Company as cash flow from operations less other productive asset purchases, operating cash flow from discontinued operations and certain cash flow adjustments, including amounts attributable to NCI and capital contributions from outside stockholders of the Company's consolidated ventures. We believe that adjusted free cash flow provides useful information to management, investors, analysts and other parties in evaluating the Company’s liquidity and credit quality assessment. Although we use adjusted free cash flow as a financial measure to assess the performance of our business, the use of adjusted free cash flow has important limitations, including that adjusted free cash flow does not reflect the cash requirements necessary to service our indebtedness, lease obligations, unconditional purchase obligations or pension and postretirement funding obligations.

• Net debt is defined by the Company as total debt less cash and cash equivalents, adjusted for amounts attributable to NCI. We believe that net debt provides useful information to management, investors, analysts and other parties in evaluating changes to the Company's capital structure and credit quality assessment.

• Return on capital employed is defined by the Company as adjusted EBIT divided by the sum of property, plant and equipment, net and trade working capital (calculated as trade receivables, net plus inventories less trade payables – third party and affiliates), adjusted for outside stockholders' interest in property, plant and equipment, net related to the Company's consolidated ventures and trade working capital amounts attributable to NCI.

2

Supplemental Information

Supplemental Information we believe to be of interest to investors, analysts and other parties includes the following:

• For those consolidated ventures in which the Company owns or is exposed to less than 100% of the economics, the outside stockholders' interests are shown as noncontrolling interests. Beginning in 2014, this includes Fairway Methanol LLC for which the Company's ownership percentage is 50%. Amounts referred to as "attributable to Celanese" are net of any applicable noncontrolling interests.

• Net sales for each of our business segments and the percentage increase or decrease in net sales attributable to price, volume, currency and other factors for each of our business segments.

• Cash dividends received from our equity and cost investments.

Results Unaudited

The results in this document, together with the adjustments made to present the results on a comparable basis, have not been audited and are based on internal financial data furnished to management. Quarterly results should not be taken as an indication of the results of operations to be reported for any subsequent period or for the full fiscal year.

Q22015 Earnings Prepared Comments

Jon Puckett, Celanese Corporation, Vice President, Investor Relations

Welcome to the Celanese Corporation second quarter 2015 financial results recording. The date of this recording is July 16, 2015. Please note that no portion of this presentation may be rebroadcast or reproduced in any form without the prior written consent of Celanese.

My name is Jon Puckett, Vice President of Investor Relations. Today you will be hearing from Mark Rohr, Chairman and Chief Executive Officer, and Chris Jensen, Senior Vice President, Finance.

The Celanese Corporation second quarter 2015 earnings release was distributed via business wire this afternoon and posted on our website, www.celanese.com, in the Investor Relations section. The slides referenced during this recording are also posted on our website. As a reminder, some of the matters discussed today and included in our presentations may include forward-looking statements concerning, for example, Celanese Corporation's future objectives and results. Please note the cautionary language contained in the posted slides. Also, some of the matters discussed and presented include references to non-GAAP financial measures. Explanations of these measures and reconciliations to the comparable GAAP measures are included on our website in the Investor Relations section under Financial Information. The earnings release, presentation and non-GAAP reconciliations are being furnished to the SEC in a Current Report on Form 8-K.

Mark Rohr will discuss our progress on aligning the company around two cores - Materials Solutions and the Acetyl Chain, review our consolidated second quarter results, provide an update on the methanol unit at Clear Lake and also update our outlook for the remainder of 2015. Chris Jensen will then comment on our earnings on a year-over-year basis and will discuss our cash flow and taxes. I'd now like to turn it over to Mark.

Mark Rohr, Celanese Corporation, Chairman of the Board of Directors and Chief Executive Officer

Thanks Jon, and I'd like to welcome everyone listening in today.

Our two complementary value creation models, Materials Solutions and the Acetyl Chain, continue to drive strong results for Celanese. In Materials Solutions, we leverage our customer relationships, polymerization technology and our application development expertise to create products and applications that drive value for customers. In the Acetyl Chain, we leverage our industry leading technology and unmatched global production platforms to serve a broader array of customers and end-use markets around the world in ways that others cannot. Together, the two value drivers share technology, fully integrated systems and research resources to increase efficiency and quickly respond to market needs, further driving value for our customers.

During the quarter, we appointed Scott Sutton to lead Materials Solutions and Pat Quarles to lead the Acetyl Chain. Both of these individuals are seasoned leaders in the chemical industry with decades of operational and managerial experience that is already benefiting their teams and our customers. Since joining Celanese two years ago, Scott has been in several leadership roles, most recently in the engineered materials business as well as ensuring we complete the methanol plant at Clear Lake on time. Scott also has broad experience at Chemtura and Albemarle. Pat comes to us after 25 years at LyondellBasell, where he most recently led the Intermediates & Derivatives business. Pat will also lead our Integrated Supply Chain function. I am really pleased to have these two accomplished leaders head up our core value propositions for Celanese. Their experience and expertise will allow us to further improve commercial and operational discipline, as well as, enhance our growth profile.

Now let's move on to the consolidated results. I am pleased to report second quarter adjusted earnings of $1.58 per share, a second quarter record for Celanese. In what is a pretty volatile market, our strong second quarter results demonstrate how we continue to execute on a value creation model and have success in delivering on our productivity initiatives.

For the company as a whole, revenue was $1.5 billion for the quarter, 2 percent higher than the first quarter on 3 percent higher volume and 1 percent lower price. Volume was higher in both cores. Increased volume in Materials Solutions was primarily driven by sequential improvements in cellulose derivatives as well as growth in engineered materials. Higher volume in the Acetyl Chain was primarily in our emulsions polymers business. We generated consolidated adjusted EBIT of $325 million realizing 22 percent margin. On a year-over-year basis, margin increased 340 basis points, driven by 520 basis point improvement in Materials Solutions margin and roughly consistent margin in the Acetyl Chain.

2

Sequentially, margin improvement of 40 basis points in Materials Solutions was offset by a 340 basis point reduction in the Acetyl Chain.

In the quarter, we generated $283 million of operating cash flow and $176 million of adjusted free cash flow. These are both second quarter records for the company and were driven primarily by strong earnings and disciplined working capital management. Our first half cash flow results put us in excellent position to generate record adjusted free cash flow for the second straight year. Chris will provide more details on our cash deployment plans in just a minute.

Moving on to Materials Solutions. Income was $207 million on revenue of $595 million. Core income margin was 34.8 percent, that's up 40 basis points sequentially and 520 basis points year-over-year. Advanced Engineered Materials generated $102 million of segment income on $346 million of revenue, or a 29.5 percent segment income margin. While these results at the segment level are consistent with the prior quarter, we generated record level earnings of $71 million in our base engineered materials business, representing growth of 16 percent sequentially and 45 percent year-over-year. These record results enabled us to offset affiliate earnings that were $12 million lower sequentially, mainly driven by lower MTBE pricing in our Ibn Sina affiliate. Sequential volume in engineered materials increased by 2 percent primarily driven by industrial applications globally, consumer applications in Asia and electronics applications in Europe also impacted the volume increase. In autos, we continue to grow faster than industry build rates and we again increased content per vehicle driven in the Asia region where we are building stronger relationships with local OEM's as well as leveraging our deep connections with U.S. and European-based producers.

We also continue to drive value through our new product launches. Our ability to grow engineered materials depends on running an efficient pipeline machine that is customer-focused and prioritized on the opportunities that are most likely to succeed and drive incremental profit. Through the first half of 2015 we launched over 500 new projects and new applications. We believe we will approach 1,000 new launches this year. Let me give you a couple of examples of the innovation that is underway at Celanese. One example, a carbon black manufacturer selected our GUR^® resin for use in a new water filtration application due to its superior efficiency in filtration and our industry based certification. Separately, we also provided unique long-fiber application for exterior structural parts [to a] heavy truck manufacturer, which allowed them to avoid costly production shut downs and provided them with a superior finished product. Our engineered materials business delivered on its promise this quarter by continuing to leverage its customer focus and ability to innovate.

In Consumer Specialties, segment income was $105 million, that's $13 million higher sequentially, on revenue of $249 million. Volume was consistent with our expectations and increased 11 percent as we saw some recovery from the first quarter destocking at our customers. Pricing was down 1 percent due to geographic product mix and a legacy flake contract. Segment income margin increased 170 basis points to 42 percent primarily due to the higher volume.

Now for the Acetyl Chain. We generated core income of $137 million on revenue of $911 million. Core income margin was 15 percent, consistent with the prior year quarter but down 340 basis points sequentially. These results are primarily reflective of the raw material movements we saw in the second quarter. Specifically, ethylene costs spiked during the quarter due to temporarily tight industry conditions primarily in Europe and Asia. In addition, weakness in demand in China during the second quarter translated to lower margin than we expected. Acetyl Chain volume increased 2 percent sequentially, primarily driven by 6 percent volume growth in emulsion polymers mainly in paints and coatings in Europe and Asia on normal seasonal patterns. This helped offset the lower demand in China for acetic acid and its derivatives. Price declined 1 percent sequentially on lower pricing in emulsion polymers and lower raw material costs, primarily VAM in Europe. I am particularly pleased with the team's ability to deliver consistent margins on a year-over-year basis, especially given the tough comparisons we had due to VAM industry conditions in the prior year's quarter. This consistency in the Acetyl Chain demonstrates the flexibility of our model that we believe is unmatched by our competition.

Shifting gears, let me take a minute to update you on methanol. The rains in Texas have truly been epic. Through the project we've lost the equivalent of 90 days due to weather. A lot of that occurring this spring. Nonetheless, we are essentially complete with all major elements of construction. Our teams on the ground are now focused on the commissioning phase of the unit. While some of our schedule flexibility has been reduced, we continue to expect this unit will start-up by October of this year. And we couldn't be more proud of the team's focus and efforts to maintain a safe and productive work site while overcoming the many challenges they have faced.

As we look to the remainder of 2015, we are seeing added stress on the global macroeconomic environment, primarily due to the recent uncertainty in China, but we continue to feel good about our ability to drive unique value in both of our cores. For the second half of the year, we expect earnings in Materials Solutions will be relatively constant with the second half of 2014 fueled by the momentum we have built in engineered materials. Second half earnings in the Acetyl Chain are expected to be lower than the second half of 2014, as we have communicated, mainly due to the impact of shifting from purchased to produced methanol and the recent uncertainty in China, but our focus on execution and productivity as

well as our agility to match market needs allows us to increase our adjusted earnings outlook range to $5.70 to $6.00 per share for this year.

With that, I'll now turn it over to Chris.

Thanks Mark.

Before I move to the results, let me add one comment on the outlook. We expect year-over-year currency headwinds in the second half of 2015 ranging from $0.30 to $0.40 due to the lower Euro Dollar exchange rate.

Now let me review the year-over-year results for the second quarter. Adjusted earnings per share for the second quarter was $1.58, a 7 percent improvement over the prior year quarter. Segment income was consistent year-over-year at $325 million, on net sales of $1.5 billion. Segment income margin increased 340 basis points year over year to 22 percent driven by Materials Solutions which expanded margin by 520 basis points to 34.8 percent. Margins in the Acetyl Chain were consistent year-over-year at 15 percent. Our commercial efforts and productivity actions successfully offset the earnings impact of the Euro, which weakened from 1.37 to 1.12 on a year-over-year basis.

Let me briefly discuss Other Activities, which was a $19 million of expense in the quarter, $21 million lower than the prior year quarter. Other Activities captures various items like corporate functions and global pension interest cost and expected asset returns. In the quarter, we saw the year-over-year benefit of our productivity actions, lower pension expense and positive foreign currency impact on certain Euro denominated costs. For the remainder of the year, we expect Other Activities will trend slightly higher than second quarter levels.

Before we move to cash flow, I want to highlight one item in our GAAP to non-GAAP reconciliation. During the quarter, we accelerated the depreciation related to our ethanol technology development unit at our Clear Lake, Texas facility to fully depreciate the unit. We made this decision because our fully operational ethanol unit in Nanjing, China combined with our pilot development unit will allow us to develop future iterations of the technology, if necessary. This decision resulted in accelerated depreciation and amortization of $39 million during the quarter which flows through R&D on our income statement.

Shifting to cash flow - we finished the quarter with $988 million of cash on our balance sheet, $137 million higher than the first quarter. Second quarter operating cash flow was $283 million and adjusted free cash flow was $176 million, both second quarter records, driven by strong earnings performance and disciplined working capital management. Net capital spending in the second quarter was $90 million. We continue to expect net capital spending for 2015 will be in the range of $350 to $400 million and should trend downward in 2016. Based on our strong earnings performance and cash flow generation for the first half of the year, we are well positioned to achieve another record year of adjusted

free cash flow in 2015. We plan to deploy our cash in 2015 on share repurchases and dividends at a level consistent with 2014 levels of about $400 million.

Now on taxes. The adjusted tax rate for the second quarter of 2015 was 18 percent compared to 21 percent in the second quarter of 2014. The lower effective rate was primarily attributable to changes in the jurisdictional mix of earnings. Net cash taxes paid were $32 million in the second quarter compared with $104 million in the prior year quarter due to both timing and jurisdictional mix. The effective US GAAP tax rate for the second quarter was 11 percent compared to 27 percent in the prior year. The lower rate was primarily due to the favorable outcome of tax audits [and judicial clarifications]. We expect the adjusted tax rate to remain consistent for the remainder of the year, but there could be some volatility in that rate due to the jurisdiction and variability of earnings.

This concludes our prepared remarks and we look forward to discussing our results with you on our earnings call Friday morning. Thank you.
