Celanese Corporation Outlines 2023 Growth Strategy and

Outlook at Investor Day

Dallas, March 25, 2021: Celanese Corporation (NYSE: CE), a global chemical and specialty materials company, will host a virtual Investor Day beginning at 9 a.m. Eastern time today from Dallas. Chairman of the Board and Chief Executive Officer, Lori Ryerkerk, and other members of Celanese's executive management team will provide details on the Company's business strategies and outline the path for growth through 2023.

"Over the last decade, Celanese has advanced on a path to build unparalleled competitive positions, implement unique business models, and ingrain commercial excellence across the organization," said Ryerkerk. "We have systematically elevated the fundamental earnings and cash generation profile of the Company over this time. As a result, Celanese has generated a total shareholder return (TSR) of 271 percent1 over the last decade and delivered positive TSR in nine of the last ten years. Additionally, we have returned a total of $6.2 billion in cash to our shareholders over the last decade through share repurchases and dividends."

Ryerkerk continued, "Our businesses have demonstrated an ability to deliver resilient and strong performance in all environments. Following a challenging 2020 global backdrop, we entered 2021 with tremendous momentum across our businesses. Today, we will outline how we are enhancing Celanese's strategy to multiply this momentum and deliver double-digit earnings per share growth annually."

Acetyl Chain

John Fotheringham, Senior Vice President, will outline the strategic actions taken over the last decade to build out the Acetyl Chain's operating flexibility with regards to product, end market, feedstock, and geography. The business implemented a unique business model to optimize its unmatched optionality and has since delivered a series of earnings and margin profile improvements.

"We will highlight actions we are taking in the Acetyl Chain to layer on additional flexibility across our global network and more dynamically operate our business daily," said Fotheringham. "In addition to the acetic acid expansion at Clear Lake, we have a number of debottlenecks and capacity additions across our product portfolio to drive continued earnings growth."

The Acetyl Chain is expected to deliver adjusted EBIT of $900 to $1,000 million in 2023.

1 December 31, 2010 - December 31, 2020

Engineered Materials

Tom Kelly, Senior Vice President, will discuss the breadth of the Engineered Materials' solution set and the evolution in how the business meets customers' needs. Engineered Materials is expected to deliver above market volume and earnings growth driven by project model enhancements and focused programs to target high-growth applications like electric vehicles, medical and pharma, 5G, and sustainability. The business continues to invest in incremental capacity expansions across its network including further investment in Asia to support local innovation.

"Beyond strengthening our project pipeline model to build further scale and improve our winning percentage, we have dedicated resources to key programs to drive early wins with customer partners in disruptive and innovative applications," said Kelly. "These programs are already contributing to our growth and allow us to gain early advantages in areas that will determine material selection for years to come."

Engineered Materials is expected to deliver adjusted EBIT of $700 to $750 million in 2023.

Acetate Tow

Lori Ryerkerk will discuss the stable earnings profile of Acetate Tow, with strong contributions from affiliates and continued productivity in the business offsetting the impact of a steady decline in secular demand.

Acetate Tow is expected to deliver a stable adjusted EBIT of approximately $245 million through 2023.

Sustainability

Ryerkerk will also discuss Celanese's approach to sustainability, the development of a company ESG Council, and recent improvements to the Company's reporting and disclosure across multiple focus areas. She will also highlight several recent initiatives focused on important environmental and societal priorities as well as a growing portfolio of products to meet rising demand for sustainable solutions.

Financial Overview

Scott Richardson, Chief Financial Officer, will discuss how Celanese's approach to balanced capital allocation has driven consistent shareholder value creation over the last decade. Under the current strategic outlook, the Company expects to continue to deliver double-digit adjusted earnings per share growth on an annualized basis. The current financial outlook period will extend through 2023, culminating with expected adjusted earnings per share of $13.00 to $14.00 per share in 2023. Over this three-year period, the Company expects to generate a total of $4 to $5 billion in operating cash flow to be deployed to drive growth.

"We are accelerating our capital deployment cycle to allocate greater capital to our highest return organic opportunities," said Richardson. "We remain committed to returning cash to our shareholders via dividends, which we expect to grow in line with future earnings, as well as share repurchases. Given robust cash generation and the strength of the Celanese balance sheet, we anticipate flexibility to deploy up to $6 billion towards other capital allocation priorities including high-return M&A and share repurchases."

The event will begin at 9:00 a.m. Eastern time and will conclude at approximately 12:00 p.m. Details and access to the live event are available at https://investors.celanese.com under News & Events/Events Calendar.

Presentation materials will be available at https://investors.celanese.com at approximately 6:00 a.m. Eastern time today. Access to a replay of the presentations will be available on the website for six months following the event.

The Company is unable to reconcile adjusted earnings per share to US GAAP diluted earnings per share, or adjusted EBIT to net earnings (loss) attributable to Celanese Corporation, on a forward-looking basis without unreasonable efforts because a forecast of Certain Items, such as mark-to-market pension gains/losses, is not practical. For more information, see "Non-GAAP Financial Measures" below.

Forward-Looking Statements

This release may contain "forward-looking statements," which include information concerning the Company's plans, objectives, goals, strategies, future revenues, synergies, performance, capital expenditures, financing needs and other information that is not historical information. All forward-looking statements are based upon current expectations and beliefs and various assumptions. There can be no assurance that the Company will realize these expectations or that these beliefs will prove correct. There are a number of risks and uncertainties that could cause actual results to differ materially from the results expressed or implied in the forward-looking statements contained in this release. These risks and uncertainties include, among other things: the extent to which the COVID-19 pandemic continues to adversely impact the economic environment, market demand and our operations, as well as the pace of any economic recovery; changes in general economic, business, political and regulatory conditions in the countries or regions in which we operate; the length and depth of product and industry business cycles, particularly in the automotive, electrical, mobility, textiles, medical, electronics and construction industries; changes in the price and availability of raw materials, particularly changes in the demand for, supply of, and market prices of ethylene, methanol, natural gas, wood pulp and fuel oil and the prices for electricity and other energy sources; the ability to pass increases in raw material prices on to customers or otherwise improve margins through price increases; the ability to maintain plant utilization rates and to implement planned capacity additions and expansions; the ability to reduce or maintain current levels of production costs and to improve productivity by implementing technological improvements to existing plants; the ability to identify desirable potential acquisition targets and to complete acquisition or investment transactions consistent with the Company's strategy; the ability to identify and execute on other attractive investment opportunities towards which to deploy capital; increased price competition and the introduction of competing products by other companies; market acceptance of our products and technology; compliance and other costs and potential disruption or interruption of production or operations due to accidents, interruptions in sources of raw materials, cyber security incidents, terrorism or political unrest, public health crises (including, but not limited to, the COVID-19 pandemic); other unforeseen events or delays in construction or operation of facilities, including as a result of geopolitical conditions, the occurrence of acts of war or terrorist incidents or as a result of weather or natural disasters or other crises including public health crises; the ability to obtain governmental approvals and to construct facilities on terms and schedules acceptable to the Company; changes in the degree of intellectual property and other legal protection afforded to our products or technologies, or the theft of such intellectual property; potential liability for remedial actions and increased costs under existing or future environmental, health and safety regulations, including those relating to climate change; potential liability resulting from pending or future litigation, or from changes in the laws, regulations or policies of governments or other governmental activities in the countries in which we operate; changes in currency exchange rates and interest rates; our level of indebtedness, which could diminish our ability to raise additional capital to fund operations or limit our ability to react to changes in the economy or the chemicals industry; tax rates and changes thereto; our ability to obtain regulatory approval for, and satisfy closing conditions to, any transactions described herein; and various other factors discussed from time to time in the Company's filings with the Securities and Exchange Commission.

The extent to which COVID-19 will adversely impact our business, financial condition and results of operations will depend on numerous evolving factors, which are highly uncertain, rapidly changing and cannot be predicted, including: the extent of any resurgence in infections and the spread of the disease, and the effectiveness of any vaccines; additional governmental, business and individual actions to contain the spread of the outbreak, including social distancing, work-at-home, stay-at-home and shelter-in-place orders and shutdowns, travel restrictions and quarantines; the extent to which these conditions depress economic activity generally and demand for our products specifically and affect the financial markets; the effect of the outbreak on our customers, suppliers, supply chain and other business partners; our ability during the outbreak to provide our products and services, including the health and well-being of our employees; business disruptions caused by actual or potential plant, workplace and office closures; the risk that we could be exposed to liability, negative publicity or reputational harm related to any incidents of actual or perceived transmission of COVID-19 among employees at our facilities; the ability of our customers to pay for our products and services during and following the outbreak; the impact of the outbreak on the financial markets and economic activity generally; our ability to access usual sources of liquidity on reasonable terms; and our ability to comply with the financial covenant in our Credit Agreement if a material and prolonged economic downturn results in increased indebtedness or substantially lower EBITDA.

Any forward-looking statement speaks only as of the date on which it is made, and the Company undertakes no obligation to update any forward-looking statements to reflect events or circumstances after the date on which it is made or to reflect the occurrence of anticipated or unanticipated events or circumstances.

Non-GAAP Financial Measures

Presentation

This document presents the Company's three business segments, Engineered Materials, Acetate Tow and Acetyl Chain.

Use of Non-US GAAP Financial Information

This release uses the following Non-US GAAP measures: adjusted EBIT and adjusted earnings per share. These measures are not recognized in accordance with US GAAP and should not be viewed as an alternative to US GAAP measures of performance or liquidity. The most directly comparable financial measure presented in accordance with US GAAP in our consolidated financial statements for adjusted EBIT is net earnings (loss) attributable to Celanese Corporation and for adjusted earnings per share is earnings (loss) from continuing operations attributable to Celanese Corporation per common share-diluted.

Definitions of Non-US GAAP Financial Measures

•Adjusted earnings per share is a performance measure used by the Company and is defined by the Company as earnings (loss) from continuing operations attributable to Celanese Corporation, adjusted for income tax (provision) benefit, Certain Items, and refinancing and related expenses, divided by the number of basic common shares and dilutive restricted stock units and stock options calculated using the treasury method. We do not provide reconciliations for adjusted earnings per share on a forward-looking basis (including those contained in this document) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of Certain Items, such as mark-to-market pension gains and losses, that have not yet occurred, are out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information.

Note: The income tax expense (benefit) on Certain Items ("Non-GAAP adjustments") is determined using the applicable rates in the taxing jurisdictions in which the Non-GAAP adjustments occurred and includes both current and deferred income tax expense (benefit). 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 and related costs, where applicable, and specifically excludes changes in uncertain tax positions, discrete recognition of GAAP items on a quarterly basis, other pre-tax 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 for GAAP. In determining the adjusted earnings per share tax rate, we reflect the impact of foreign tax credits when utilized, or expected to be utilized, absent discrete events impacting the timing of foreign tax credit utilization. We analyze this rate quarterly and adjust it 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. Table 3a of our Non-US GAAP Financial Measures and Supplemental Information document summarizes the reconciliation of our estimated GAAP effective tax rate to the adjusted tax rate. The estimated GAAP rate excludes discrete recognition of GAAP items due to our inability to forecast such items. As part of the year-end reconciliation, we will update the reconciliation of the GAAP effective tax rate to the adjusted tax rate for actual results.

Reconciliation of Non-US GAAP Financial Measures

Refer to Exhibits 99.3A and 99.3B of the accompanying Form 8-K, and which are also available on the Investor Relations/Financial Information/Non-GAAP Financial Measures page of our website, www.celanese.com, for additional definitions and reconciliations of non-GAAP financial measures.

Celanese Corporation Increases 2021 Financial Outlook

Dallas, March 24, 2021: Celanese Corporation (NYSE: CE), a global chemical and specialty materials company, today increased its full year 2021 outlook for adjusted earnings of $11.00 to $11.50 per share. The midpoint of the new guidance range represents a 15 percent increase over the prior range of $9.50 to $10.00.

"While Winter Storm Uri had an unprecedented impact on Texas and our gulf coast operations, I am pleased to share that our Clear Lake, Bishop, and Bay City facilities are all operational with most units producing at pre-storm levels", said Lori Ryerkerk, chairman and chief executive officer. "Amid tightened market conditions following Winter Storm Uri, we expect a strong finish to the first quarter with adjusted earnings around $3.00 per share. We expect momentum to continue across the middle of 2021 as we meet elevated demand for our Acetyl Chain and Engineered Materials products. By accelerating major turnarounds from 2021 into 2020, we are uniquely positioned to reliably supply markets which we expect will remain tight into the middle of the year following the winter storm."

The Company is unable to reconcile adjusted earnings per share to US GAAP diluted earnings per share on a forward-looking basis without unreasonable efforts because a forecast of Certain Items, such as mark-to-market pension gains/losses, is not practical. For more information, see "Non-GAAP Financial Measures" below.

Exhibit 99.3A

Non-US GAAP Financial Measures and Supplemental Information

January 28, 2021

In this document, the terms the "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 three business segments, Engineered Materials, Acetate Tow and Acetyl Chain.

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 because the Company believes them to be important supplemental measures for assessing our financial and operating results and as a means to evaluate our financial condition and 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), operating margin, cash flow from operating activities (together with cash flow from investing and financing activities), earnings per share or any other US GAAP financial measure. These non-GAAP financial measures should be considered within the context of our complete audited and unaudited financial results for the given period, which are available on the Financial Information/Financial Document Library page of our website, investors.celanese.com. The definition and 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 in this document, in the presentation itself or on a Form 8-K in connection with the presentation on the Financial Information/Financial Document Library page of our website, investors.celanese.com, 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 document includes definitions and reconciliations of non-GAAP financial measures used from time to time by the Company.

Specific Measures Used

This document provides information about the following non-GAAP measures: adjusted EBIT, adjusted EBIT margin, operating EBITDA, operating EBITDA margin, operating profit (loss) attributable to Celanese Corporation, adjusted earnings per share, net debt, free cash flow and return on invested capital (adjusted). 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) attributable to Celanese Corporation; for adjusted EBIT margin and operating EBITDA margin is operating margin; for operating profit (loss) attributable to Celanese Corporation is operating profit (loss); for adjusted earnings per share is earnings (loss) from continuing operations attributable to Celanese Corporation per common share-diluted; for net debt

is total debt; for free cash flow is net cash provided by (used in) operations; and for return on invested capital (adjusted) is net earnings (loss) attributable to Celanese Corporation divided by the sum of the average of beginning and end of the year short- and long-term debt and Celanese Corporation stockholders' equity.

Definitions

•Adjusted EBIT is a performance measure used by the Company and is defined by the Company as net earnings (loss) attributable to Celanese Corporation, plus (earnings) loss from discontinued operations, less interest income, plus interest expense, plus refinancing expense and taxes, and further adjusted for Certain Items (refer to Table 8). We believe that adjusted EBIT provides transparent and useful information to management, investors, analysts and other parties in evaluating and assessing our primary 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 do not provide reconciliations for adjusted EBIT on a forward-looking basis (including those contained in this document) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of Certain Items, such as mark-to-market pension gains and losses, that have not yet occurred, are out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information. Adjusted EBIT margin is defined by the Company as adjusted EBIT divided by net sales. Adjusted EBIT margin has the same uses and limitations as Adjusted EBIT.

•Operating EBITDA is a performance measure used by the Company and is defined by the Company as net earnings (loss) attributable to Celanese Corporation, plus (earnings) loss from discontinued operations, less interest income, plus interest expense, plus refinancing expense, taxes and depreciation and amortization, and further adjusted for Certain Items, which Certain Items include accelerated depreciation and amortization expense. Operating EBITDA is equal to adjusted EBIT plus depreciation and amortization. We believe that Operating EBITDA provides transparent and useful information to investors, analysts and other parties in evaluating our operating performance relative to our peer companies. Operating EBITDA margin is defined by the Company as Operating EBITDA divided by net sales. Operating EBITDA margin has the same uses and limitations as Operating EBITDA.

•Operating profit (loss) attributable to Celanese Corporation is defined by the Company as operating profit (loss), less earnings (loss) attributable to noncontrolling interests ("NCI"). We believe that operating profit (loss) attributable to Celanese Corporation provides transparent and useful information to management, investors, analysts and other parties in evaluating our core operational performance. Operating margin attributable to Celanese Corporation is defined by the Company as operating profit (loss) attributable to Celanese Corporation divided by net sales. Operating margin attributable to Celanese Corporation has the same uses and limitations as Operating profit (loss) attributable to Celanese Corporation.

•Adjusted earnings per share is a performance measure used by the Company and is defined by the Company as earnings (loss) from continuing operations attributable to Celanese Corporation, adjusted for income tax (provision) benefit, Certain Items, and refinancing and related expenses, divided by the number of basic common 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 primary operating results from period-to-period after removing the impact of the above stated items that affect comparability and as a performance metric in the Company's incentive compensation plan. We do not provide reconciliations for adjusted earnings per share on a forward-looking basis (including those contained in this document) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of Certain Items, such as mark-to-market pension gains and losses, that have not yet occurred, are out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information.

Note: The income tax expense (benefit) on Certain Items ("Non-GAAP adjustments") is determined using the applicable rates in the taxing jurisdictions in which the Non-GAAP adjustments occurred and includes both current and deferred income tax expense (benefit). 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 and related costs, where applicable, and specifically excludes changes in uncertain tax positions, discrete recognition of GAAP items on a quarterly basis, other pre-tax 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 for GAAP. In determining the adjusted earnings per share tax rate, we reflect the impact of foreign tax credits when utilized, or expected to be utilized, absent discrete events impacting the timing of foreign tax credit utilization. We analyze this rate quarterly and adjust it 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. Table 3a summarizes the reconciliation of our estimated GAAP effective tax rate to the adjusted tax rate. The estimated GAAP rate excludes discrete recognition of GAAP items due to our inability to forecast such items. As part of the year-end reconciliation, we will update the reconciliation of the GAAP effective tax rate to the adjusted tax rate for actual results.

•Free cash flow is a liquidity measure used by the Company and is defined by the Company as net cash provided by (used in) operations, less capital expenditures on property, plant and equipment, and adjusted for capital contributions from or distributions to Mitsui & Co., Ltd. ("Mitsui") related to our methanol joint venture, Fairway Methanol LLC ("Fairway"). We believe that free cash flow provides useful information to management, investors, analysts and other parties in evaluating the Company's liquidity and credit quality assessment because it provides an indication of the long-term cash generating ability of our business. Although we use free cash flow as a measure to assess the liquidity generated by our business, the use of free cash flow has important limitations, including that 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. 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 invested capital (adjusted) is defined by the Company as adjusted EBIT, tax effected using the adjusted tax rate, divided by the sum of the average of beginning and end of the year short- and long-term debt and Celanese Corporation stockholders' equity. We believe that return on invested capital (adjusted) provides useful information to management, investors, analysts and other parties in order to assess our income generation from the point of view of our stockholders and creditors who provide us with capital in the form of equity and debt and whether capital invested in the Company yields competitive returns.

Supplemental Information

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

•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 investments.

•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 NCI. Beginning in 2014, this includes Fairway for which the Company's ownership percentage is 50%. Amounts referred to as "attributable to Celanese Corporation" are net of any applicable NCI.

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.

Supplemental Non-US GAAP Financial Measures

March 25, 2021

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

Purpose

Presentation

This document presents the Company's three business segments, Engineered Materials, Acetate Tow and Acetyl Chain.

Use of Non-US GAAP Financial Measures

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

Specific Measures Used

Definitions

•Adjusted earnings per share is a performance measure used by the Company and is defined by the Company as earnings (loss) from continuing operations attributable to Celanese Corporation, adjusted for income tax (provision) benefit, Certain Items, and refinancing and related expenses, divided by the number of basic common 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 primary operating results from period-to-period after removing the impact of the above stated items that affect comparability and as a performance metric in the Company's incentive compensation plan. We do not provide reconciliations for adjusted earnings per share on a forward-looking basis (including those contained in this document) when we are unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the timing and amount of Certain Items, such as mark-to-market pension gains and losses, that have not yet occurred, are out of our control and/or cannot be reasonably predicted. For the same reasons, we are unable to address the probable significance of the unavailable information.

Note: The income tax expense (benefit) on Certain Items ("Non-GAAP adjustments") is determined using the applicable rates in the taxing jurisdictions in which the Non-GAAP adjustments occurred and includes both current and deferred income tax expense (benefit). 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 and related costs, where applicable, and specifically excludes changes in uncertain tax positions, discrete recognition of GAAP items on a quarterly basis, other pre-tax 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 for GAAP. In determining the adjusted earnings per share tax rate, we reflect the impact of foreign tax credits when utilized, or expected to be utilized, absent discrete events impacting the timing of foreign tax credit utilization. We analyze this rate quarterly and adjust it 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. Table 3a summarizes the reconciliation of our GAAP effective tax rate to the adjusted tax rate.

management, investors, analysts and other parties in evaluating the Company's liquidity and credit quality assessment because it provides an indication of the long-term cash generating ability of our business. Although we use free cash flow as a measure to assess the liquidity generated by our business, the use of free cash flow has important limitations, including that 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.

Supplemental Information

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

•Net sales for each of our business segments.

•Cash dividends received from our equity investments.
