Item 1.    BUSINESS
BUSINESS OVERVIEW
W. R. Grace & Co. is engaged in the production and sale of specialty chemicals and specialty materials on a global basis through two reportable business segments: Grace Catalysts Technologies, which includes catalysts and related products and technologies used in refining, petrochemical and other chemical manufacturing applications; and Grace Materials Technologies, which includes specialty materials, including silica-based and silica-alumina-based materials, used in consumer/pharma, chemical process, and coatings consumer, industrial, and pharmaceutical applications. We entered the specialty chemicals industry in 1954, the year in which we acquired the Davison Chemical Company.
Grace is the successor to a company that began in 1854 and originally became a public company in 1953. We entered the specialty chemicals and specialty materials industries in 1954, the year in which we acquired the Davison Chemical Company. W. R. Grace & Co. is a Delaware corporation. Our principal executive offices are located at 7500
Developments
On April 3, 2018, using cash on hand and borrowings under our credit agreement, we acquired the assets of the polyolefin catalysts business of Albemarle Corporation. We acquired the business for $418.0 million, net of cash acquired and including customary post-closing adjustments. The business is included in the Specialty Catalysts operating segment of the Grace Drive, Columbia, Maryland 21044, telephone (410) 531-4000. As of December 31, 2016, we had approximately 3,700 global employees.Catalysts Technologies reportable segment. The acquisition is complementary to our existing specialty catalysts business and strengthens our commercial relationships, catalysts technology portfolio, and manufacturing network.
On January 27, 2016, Grace entered into a separation agreement with GCP Applied Technologies Inc., then a wholly-owned subsidiary of Grace ("GCP"(“GCP”), pursuant to which Grace agreed to transfer its Grace Construction Products operating segment and the packaging technologies business of its Grace Materials Technologies operating segment to GCP (the "Separation"“Separation”). Grace and GCP completed the Separation on February 3, 2016 (the "Distribution Date"“Distribution Date”), by means of a pro rata distribution to the Company'sCompany’s stockholders of all of the outstanding shares of GCP common stock (the "Distribution"“Distribution”), with one share of GCP common stock distributed for each share of Company common stock held as of the close of business on January 27, 2016. As a result of the Distribution, GCP became an independent public company. GCP’s historical financial results through the Distribution Date are reflected in Grace’s Consolidated Financial Statements as discontinued operations.
On June 30, 2016, we completed the acquisition of the assets of the BASF Polyolefin Catalysts business (the "polyolefin catalysts acquisition"), which included technologies, patents, trademarks, and production plants in Pasadena, Texas, and Tarragona, Spain, forFebruary 3, 2014, Grace concluded a purchase price of $250.6 million. We added the following technologies to our catalysts portfolio: (1) LYNX® high-activity polyethylene ("PE") catalyst technologies used commercially in slurry processes for the production of high-density PE resins such as bimodal film and pipe, and (2) LYNX® polypropylene ("PP") catalyst technologies used commercially in all major PP process technologies including slurry, bulk loop, stirred gas, fluid gas, and stirred bulk. The acquisition also provided us with significant additional flexibility and capacity for our global polyolefin catalysts manufacturing network.
In 2016, we exited certain product lines that were previously part of our Discovery Sciences product group included in our Grace Materials Technologies operating segment, as these product lines no longer fit into our strategic growth plans. As part of the exit, we sold certain assets to unaffiliated buyers for aggregate proceeds of $12.9 million.
In 2001, Grace and 61 of its United States subsidiaries and affiliates filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware. On February 3, 2014,Delaware, when the joint plan of reorganization (the "Joint Plan"“Joint Plan”) filed by Grace and certain other parties became effective, concluding Grace’s status as a debtor under Chapter 11.

Grace Catalysts Technologies—Refining Catalysts
FCC Catalysts
We are a global leader in developing and manufacturing fluid catalytic cracking, or FCC, catalysts and additives that are designed to enable petroleum refiners to increase profits by improving product yields, value and quality. Our FCC products also enable refiners to reduce emissions from their FCC units and reduce sulfur content in the transportation fuels they produce. Oil refining is a highly specialized discipline and FCC catalysts must be tailored to meet local variations in crude oil feedstocks and a refinery'srefinery’s product mix. We work regularly with our customers to identify the most appropriate catalyst and additive formulations for their changing needs.
Since our customers are refiners, our business is highly dependent on the economics of the petroleum refining industry. In particular, demand for our FCC products is affected by refinery throughput, the type and quality of refinery feedstocks, and the demand for transportation fuels and other refinery products, such as propylene.

In general, as a refinery utilizes more of its FCC unit capacity, it needs a greater amount of FCC catalyst. Refinery throughput, or the extent to which refiners utilize their available FCC capacity, is generally determined by demand for transportation fuels and petrochemical products and the availability of crude oil supply. In recent years, global economic growth, especially in emerging regions, has increased global demand for transportation fuels and petrochemical products. Retail gasoline and diesel fuel prices and the level of economic activity has also directly influenced transportation fuel demand. Improvements in vehicular fuel economy, as well as consumer trends and government policies that increase the use of non-petroleum-based fuels and/or decrease the use of petroleum-based fuels also will affect transportation fuel demand over time.
Refinery crude oil feedstocks vary in quality from light and sweet to heavy and sour. Light and sweet feedstocks are typically more expensive than heavy and sour feedstocks and yield a greater proportion of high-value petroleum products. They also yield a lower proportion of residual oil, or "resid," which is generally the lowest value feedstock contained in crude oil. Although heavy and sour feedstocks with high resid content are typically less expensive than higher quality feedstocks, the processing of high-resid feedstocks is more difficult because these feedstocks have more impurities and higher boiling points. Our customers generally determine the feedstocks to be used in their refineries based on relative pricing and availability of various quality feedstocks. Refinery configuration and complexity also plays a role in feedstock selection; more complex refineries tend to process a higher proportion of heavy and sour feedstocks. In general, as a refinery uses more heavy and sour feedstocks, it uses a greater amount of FCC catalyst. In addition, refiners use special high value-added formulations of FCC catalysts for efficient refining of heavy and sour feedstocks. We have designed our MIDAS® catalyst, IMPACT® catalyst, NEKTOR™ catalyst, and GENESIS® catalyst product portfolios to enable our customers to increase the efficiency and yield of high-resid feedstock refining.
Heavy and sour crude oil has a relatively high level of metals, nitrogen and sulfur contamination. Many countries and regions, including the U.S., European Union, Japan, Russia, India and China have imposed regulatory limitations on the sulfur content of gasoline and diesel fuel. We have developed a portfolio of products designed to assist refiners in meeting their gasoline sulfur-reduction targets, including our D-PRISM® and GSR® additives and our SURCA® catalyst family.
Within certain limits, refiners have the ability to adjust their relative output of transportation fuels versus petrochemicals. Global economic growth, especially in emerging regions, has increased the demand for plastics. As a result, some of our refinery customers have sought increased profits from petrochemicals by increasing the yield of propylene from their FCC units. Our ZSM-5-based technology, including our OLEFINSMAX® and OLEFINSULTRA® additive products, is designed to maximize the propylene output of FCC units.
ManyAlso, many U.S. petroleum refiners have entered into consent decrees with the U.S. Environmental Protection Agency (the "EPA"“EPA”) under which the refiners have agreed to reduce emissions of nitrogen oxides and sulfur oxides. The European Union has also imposed requirements on refineries with respect to nitrogen oxides and sulfur oxides emissions. FCC units are generally the largest emitters of these pollutants in a refinery. Our additives are designed to assist refineries in meeting their obligations to reduce these pollutants. Our Super DESOX® additive reduces sulfur oxides emissions from commercial FCC units. Our DENOX® additives are designed to achieve reductions in nitrogen oxides emissions comparable to those obtained from capital intensive

alternatives available to a refinery, while our non-platinum-based combustion promoters XNOX® and CP®P are designed to enable refiners to control carbon monoxide emissions without increasing nitrogen oxides.
Competition in FCC catalysts and additives is based on technology, product performance, customer service and price. Our principal global FCC catalyst competitors are Albemarle Corp., BASF, and SINOPEC. Our principal global competitors in FCC additives are BASF and Johnson Matthey. We also have multiple regional competitors for FCC catalysts and additives.
Hydroprocessing Catalysts
We market most of our hydroprocessing catalysts primarily through ART, our Advanced Refining Technologies LLC (“ART”) joint venture with Chevron.Chevron Products Company (“Chevron”). We hold a 50% economic interest in ART, which is not consolidated in our financial statements so ART’s sales are excluded from our sales. We established ART to combine our technology with that of Chevron and to develop, market and sell hydroprocessing catalysts to customers in the petroleum refining industry worldwide.
As discussed above, our business is dependent on the economics of the petroleum industry. We are a leading supplier of hydroprocessing catalysts designed for processing high resid content feedstocks. We offer products for fixed-bed resid hydrotreating, on-stream catalyst replacement, and ebullating-bed resid hydrocracking processes.
We also offer a full line of catalysts, customized for individual refiners, used in distillate hydrotreating to produce ultra-low sulfur content gasoline and diesel fuel, including our SMARTSmART CATALYST SYSTEM® and APART® catalyst systems. As discussed above, regulatory limitations on the sulfur content of gasoline and diesel fuel are becoming more common. These products are designed to help refiners to reduce the sulfur content of their products.
We have rights to sell hydrocracking and lubes hydroprocessing catalysts to licensees of Chevron Lummus Global (“CLG”) and other petroleum refiners for unit refills. These rights allow us to streamline hydroprocessing catalyst supply and improve technical service for refining customers by establishing ART as their single point of contact for all their hydroprocessing catalyst needs.
Competition in the hydroprocessing catalyst industry is based on technology, product performance, customer service and price. Criterion, Albemarle, Haldor Topsoe, UOP and Axens are our leading global competitors in hydroprocessing catalysts. We also have multiple regional competitors.

We have geographically distributed our sales and technical service professionals to make them responsive to the needs of our geographically diverse customers. We typically operate under long-term contracts with our customers.
Seasonality does not have a significant overall effect on our Catalysts Technologies reportable segment. However, sales of FCC catalysts tend to be lower in the first calendar quarter prior to the shift in production by refineries from home heating oil for the winter season to gasoline production for the summer season. FCC catalysts and ebullating-bed hydroprocessing catalysts are consumed at a relatively steady rate and are replaced regularly. Fixed-bed hydroprocessing catalysts are consumed over a period of years and are replaced in bulk in an irregular pattern. Since our customers periodically shut down their refining processes to replace fixed-bed hydroprocessing catalysts in bulk, our hydroprocessing catalyst sales to any customer can vary substantially over the course of a year and between years based on that customer's catalyst replacement schedule.
The principal raw materials for Catalysts Technologies products include molybdenum oxide, zeolite, caustic soda, sodium aluminate, aluminum sulfate, alumina and derivatives, sodium silicate, nickel, rare earths, aluminum metal, and tungsten salt. Multiple suppliers are generally available for each of these materials; however, some of our raw materials may be provided by single sources of supply. We seek to mitigate the risk of using single source suppliers by identifying and qualifying alternative suppliers or, for unique materials, by using alternative formulations from other suppliers or by passing price increases on to customers. In some instances, we produce our own raw materials and intermediates.
Prices for many of our raw materials, including metals, and energy can be volatile. In response to increases in raw material and energy costs, we generally take actions to mitigate the effecteffects of higher costs including increasing prices, developing alternative formulations for our products, increasing productivity, and hedging purchases of certain raw materials.
As in many chemical businesses, we consume significant quantities of natural gas in the production of Catalysts Technologies products. World events and other economic factors cause volatility in the price of natural gas. Increases or decreases in the cost of natural gas and raw materials can have a significant impact on our operating margins. We have implemented a risk management program under which we hedge natural gas in a way that is designed to provide protection against price volatility. See also disclosure
Seasonality
Seasonality does not have a significant overall effect on our Catalysts Technologies reportable segment. However, under traditional patterns, sales of FCC catalysts have tended to be lower in the first calendar quarter due to maintenance outages taken prior to the shift in production by refineries from home heating oil for the winter season to gasoline production for the summer season. FCC catalysts and ebullating-bed hydroprocessing catalysts are consumed at a relatively steady rate and are replaced regularly. Fixed-bed hydroprocessing catalysts are consumed over a period of years and are replaced in bulk in an irregular pattern. Since our customers periodically shut down their refining processes to replace fixed-bed hydroprocessing catalysts in bulk, our hydroprocessing catalyst sales to any customer can vary substantially over the course of a year and between years based on that customer’s catalyst replacement schedule.

INTELLECTUAL PROPERTY; RESEARCH ACTIVITIES
Competition in the specialty chemicals and specialty materials industry is often based on technological superiority and innovation. Our ability to maintain our margins and effectively compete with other suppliers depends on our ability to introduce new products based on innovative technology, as well as our ability to obtain patent or other intellectual property protection. Our research and development programs emphasize development of new products and processes, improvement of existing products and processes, and application of existing products and processes to new industries and uses. MostWe conduct most of our research activity is conducted in North America and Europe.

Table of Contents

We selectively file and obtain patents in our Refining Technologies business, as well as in our chemical catalysts product line in our Specialty Catalysts business, for strategic new products or for significant business opportunities. We routinely file and obtain patents in a number of countries around the world that are significant to our businessespolyolefin catalysts product line in our Specialty Catalysts business. In our Materials Technologies business, we focus our research on the development and use of materials-based specialty products, and expertise for diverse applications. We file patents and use trade secret protection to protect our unique products, processes and expertise in strategic segments of the business, and to cover key product innovations in adjacent market segments. We file and obtain patents and trademarks in various countries to strengthen and protect our product offerings globally.
We file patents in order to protect our investments in innovation, research, and product development. Numerous patents and patent applications protect our products, formulations, manufacturing processes, equipment, and improvements. We also benefit from the use of trade secret information, including know-how and other proprietary information relating to many of our products and processing technologies. There can be no assurance, however, that our patents, patent applications and precautions to protect trade secrets and know-how will provide sufficient protection for our intellectual property. In addition, other companies may independently develop technology that could replicate, and thus diminish the advantage provided by, our trade secrets. Other companies may also develop alternative technology or design-arounds that could circumvent our patents or may acquire patent rights applicable to our business which might interpose a limitation on expansion of our business in the future.
Research and development expenses were approximately $49 million, $47 million, and $51 million in 2016, 2015, and 2014, respectively. These amounts include depreciation and amortization expenses related to research and development assets and expenses incurred in funding external research projects. The amount of research and development expenses relating to government- and customer-sponsored projects (rather than projects that we sponsor) was not material during these periods. Grace also conducts research and development activities with our ART joint venture, which are not included in the amounts above.
ENVIRONMENT, HEALTH AND SAFETY MATTERS
We are subject, along with other manufacturers of specialty chemicals, to stringent regulations under numerous regional, national, provincial, state and local environment, health and safety laws and regulations relating to the manufacture, storage, handling, disposal and stewardship of chemicals and other materials. Environmental laws require that certain responsible parties, as defined in the relevant statute, fund remediation actions regardless of legality of original disposal or ownership of a disposal site. We are involved in various response actions to address the presence of chemical substances as required by applicable laws.
We have expended substantial funds to comply with environmental laws and regulations and expect to continue to do so in the future. The following table sets forth our expenditures in the past three years, and our estimated expenditures in 20172019 and 2018,2020, for (i) the operation and maintenance of manufacturing facilities and the disposal of wastes; (ii) capital expenditures for environmental control facilities; and (iii) site remediation:

Risks Related to the Business
The global scope of our operations subjects us to the risks of doing business in foreign countries, and with other parties located in foreign jurisdictions, which could adversely affect our business, financial condition and results of operations.
We operate our business on a global scale with approximately 72% of our 20162018 sales outside the United States. We operate and/or sell to customers in over 6070 countries and in over 30 currencies. We currently have many production facilities, research and development facilities and administrative and sales offices located outside North America, including facilities and offices located in EMEA (Europe Middle East Africa), Asia Pacific and Latin America. We expect non-U.S. sales to continue to represent a substantial majority of our revenue. Accordingly, our business is subject to risks related to the differing legal, political, social and regulatory requirements and economic conditions of many jurisdictions. Risks inherent in non-U.S. operations include the following:
commercial agreements may be more difficult to enforce and receivables more difficult to collect;
intellectual property rights may be more difficult to enforce;
increased shipping costs, disruptions in shipping or reduced availability of freight transportation;
we may have difficulty transferring our profits or capital from foreign operations to other countries where such funds could be more profitably deployed;
we may experience unexpected adverse changes in export duties, quotas and tariffs and difficulties in obtaining export licenses;

Table of Contents

some foreign countries have adopted, and others may impose, additional withholding and other taxes or adopt other restrictions on foreign trade or investment, including import, currency exchange and capital controls, charges and limitations;
foreign governments may nationalize private enterprises;
our business and profitability in a particular country could be affected by political or economic repercussions on a domestic, country-specific or global level from terrorist activities and the response to such activities;
we may be affected by unexpected adverse changes in foreign laws or regulatory requirements;
we may have to pay increased cash taxes in the event of a change in tax laws, regulations or interpretations in one or more foreign jurisdictions, and our business, financial condition or results of operations, or liquidity could be adversely affected; and
we are exposed to geopolitical risk, where unexpected changes in global, regional, or local political or social conditions could adversely affect our foreign operations.
Our success as a global business will depend, in part, upon our ability to succeed in differing legal, regulatory, economic, social and political conditions by developing, implementing and maintaining policies and strategies that are effective in each location where we do business.
In addition to the risks and uncertainties that we discussed above, recent world events have increased the risks posed by international trade disputes, tariffs, and sanctions. We procure a wide spectrum of commodities globally to support our production. For materials sourced from nations that could be impacted by trade disputes, tariffs or sanctions, we could potentially face increased costs, supply disruptions and/or costs associated with securing alternative materials. Additionally, such disputes, tariffs, and sanctions could potentially lead to a reduction in our sales of products, technology, and services. We view geopolitical risk along with other potential supply chain and sales risks, and work actively to diversify and mitigate these potential impacts; however, such events could adversely affect our business, financial condition and results of operations.
We are exposed to currency exchange rate changes that impact our profitability.
We are exposed to currency exchange rate risk through our U.S. and non-U.S. operations. Changes in currency exchange rates may materially affect our operating results. For example, changes in currency exchange rates may affect the relative prices at which we and our competitors sell products in the same region and the cost of materials used in our operations. A substantial portion of our net sales and assets are denominated in currencies other than the U.S. dollar, particularly the euro. When the U.S. dollar strengthens against other currencies, at a constant level of business, our reported sales, earnings, assets and liabilities are reduced because the non-U.S. currencies translate into fewer U.S. dollars.
We incur a currency transaction risk whenever one of our operating subsidiaries enters into either a purchase or a sales transaction using a currency different from the operating subsidiary'ssubsidiary’s functional currency. Given the volatility of exchange rates, we may not be able to manage our currency transaction risks effectively, or volatility in currency exchange rates may expose our financial condition or results of operations to a significant additional risk.
Prices for certain raw materials and energy are volatile and can have a significant effect on our manufacturing and supply chain strategies as we seek to maximize our profitability. If we are unable to successfully adjust our strategies in response to volatile raw materials and energy prices, such volatility could have a negative effect on our earnings in future periods.
We use petroleum-based materials, metals, natural gas, petroleum-based materials, and other materials in the manufacture of our products. We consume substantial amounts of energy in our manufacturing processes. Prices for these materials and energy are volatile and can have a significant effect on our pricing, sales, manufacturing and supply chain strategies as we seek to maximize our profitability. Our ability to successfully adjust strategies in response to

Table of Contents

volatile raw material and energy prices is a significant factor in maintaining or improving our profitability. If we are unable to successfully adjust our strategies in response to volatile prices, such volatility could have a negative effect on our sales and earnings in future periods.

Table of Contents

A substantial portion of our raw materials are commodities whose prices fluctuate as market supply and demand fundamentals change.
We attempt to manage exposure to price volatility of major commodities through:
long-term supply contracts;
contracts with customers that permit adjustments for changes in prices of commodity-based materials and energy;
forward buying programs that layer in our expected requirements systematically over time; and
limited use of financial instruments.
Although we regularly assess our exposure to raw material price volatility, we cannot always predict the prospects of volatility and we cannot always cover the risk in a cost effective manner.
We have a policy of maintaining, when available, multiple sources of supply for raw materials. However, certain of our raw materials may be provided by single sources of supply. We may not be able to obtain sufficient raw materials due to unforeseen developments that would cause an interruption in supply. Even if we have multiple sources of supply for raw materials, these sources may not make up for the loss of a major supplier.
If we are not able to continue our technological innovation and successful introduction of new products, our customers may turn to other suppliers to meet their requirements.
The specialty chemicals industryand specialty materials industries and the end-use markets into which we sell our products experience ongoing technological change and product improvements. A key element of our business strategy is to invest in research and development activities with the goal of introducing new high-performance, technically differentiated products. We may not be successful in developing new technology and products that effectively compete with products introduced by our competitors, and our customers may not accept, or may have lower demand for, our new products. If we fail to keep pace with evolving technological innovations or fail to improve our products in response to our customers’ needs, then our business, financial condition and results of operations could be adversely affected as a result of reduced sales of our products.
We spend large amounts of money for environmental compliance in connection with our current and former operations.
As a manufacturer of specialty chemicals and specialty materials, we are subject to stringent regulations under numerous U.S. federal, state, local and foreign environmental, health and safety laws and regulations relating to the generation, storage, handling, discharge, disposition and stewardship of chemicals and other materials. We have expended substantial funds to comply with such laws and regulations and have established a policy to minimize our emissions to the environment. Nevertheless, legislative, regulatory and economic uncertainties (including existing and potential laws and regulations pertaining to climate change) make it difficult for us to project future spending for these purposes, and if there is an acceleration in new regulatory requirements, we may be required to expend substantial additional funds to remain in compliance.
We are subject to environmental clean-up costs, fines, penalties and damage claims that have been and continue to be costly.
In the U.S., we are subject to lawsuits and regulatory actions, in connection with current and former operations (including some divested businesses and off-site disposal facilities), that seek clean-up or other remedies. We are also subject to similar risks outside of the U.S.
We operated a vermiculite mine in Libby, Montana, until 1990. Some of the vermiculite ore that was mined at the Libby mine contained naturally occurring asbestos. We are cooperating with the U.S. Environmental Protection Agency (the "EPA"(or the “EPA”) and other federal, state and local governmental agencies in a remedial investigation and feasibility study (“RI/(or the “RI/FS”) of the Libby mine and the surrounding area, known as Operable Unit 3 (or “OU3”), to determine the location, scope and extent of required remediation. The RI/FS will determine the specific areas within OU3 requiring remediation and will identify possible remedial action alternatives. Possible remedial actions within OU3 are wide-ranging, from institutional controls such as land use restrictions, to more active measures involving soil removal, containment projects, or other protective measures. As part of the RI/FS process, we contracted an engineering and consulting firm to develop a range of possible remedial

Table of Contents

alternatives and associated cost estimates for OU3. Based on this work, we recorded a pre-tax charge of $70.0 million in the 2018 third quarter for the estimated costs of remediation of OU3.
The estimated costs of remediation are preliminary and consist of several components, each of which may vary significantly as the remedial alternatives are further developed and analyzed by the regulatory bodies providing oversight. It is reasonably possible that the ultimate costs of remediation could range between $30 million and $170 million. The ultimate remedy will be determined by the EPA after the RI/FS is finalized. Such remedy will be set forth in a Record of Decision (or “ROD”) that is expected to be issued by the EPA during or after 2020. Costs associated with the more active remedial alternatives would be expected to be incurred over a decade or more. We will reevaluate our estimated liability as remedial alternatives evolve based on further work by the engineering and consulting firm and discussions with the EPA as the RI/FS process moves toward a ROD. Depending on the remedial alternatives that the EPA selects in the ROD, the total cost of remediating OU3 may exceed our current estimate by material amounts.
The EPA is also investigating or remediating formerly owned or operated sites that processed Libby vermiculite into finished products. We are cooperating with the EPA on these

Table of Contents

investigation and remediation activities, and have recorded a liability to the extent that our review has indicated that a probable liability has been incurred and the cost is estimable.
We have recorded liabilities for all environmental matters for which a loss is considered to be probable and sufficient information is available to reasonably estimate the loss. These liabilitiesWe also face legacy environmental liability for response costs at sites not related to our former vermiculite mining and processing activities. This liability relates to our former businesses or operations, including our share of liability at off-site disposal facilities. Our estimated liability is based upon regulatory requirements and environmental conditions at each site. As we receive new information, our estimated liability may increase materially.
We may be required to make one or more contingent deferred payments to the asbestos property damage trust, or PD Trust, in respect of property damage claims related to our former Zonolite attic insulation (“ZAI”) product installed in the U.S. (“ZAI PD Claims”); we may also be obligated to make additional payments to the PD trust in respect of “Other PD Claims” (those being asbestos property damage claims other than ZAI PD Claims); and our obligations to make payments to the PD Trust in respect of Other PD Claims is not capped.
Under the Joint Plan of reorganization that concluded Grace’s status as a debtor under Chapter 11, as discussed above, the PD Trust has been established and funded under Section 524(g) of the Bankruptcy Code. The order of the Bankruptcy Court confirming the Joint Plan contains a channeling injunction, which provides that all pending and future asbestos-related property damage claims and demands (or “PD Claims”) can only be brought against the PD Trust. The PD Trust contains two accounts. One of these accounts is the “ZAI PD Account,” which is funded in respect of claims related to our former Zonolite Attic Insulation product, or “ZAI.” The other account, the “PD Account,” is funded solely in respect of PD Claims excluding those PD Claims related to ZAI (which we refer to as “Other PD Claims”). Grace emerged from bankruptcy on February 3, 2014 (the “Effective Date”).
We have satisfied all of our financial obligations to the PI Trust. We have contingent financial obligations remaining to the PD Trust. With respect to ZAI PD Claims, the PD Trust was funded with $34.4 million on the Effective Date and $30.0 million on February 3, 2017. We are also obligated to make up to 10 contingent deferred payments of $8 million per year to the PD Trust in respect of ZAI PD Claims during the 20-year period which began on February 3, 2019, with each such payment due only if the assets of the PD Trust in respect of ZAI PD Claims fall below $10 million during the preceding year. As of December 31, 2018, we have evaluated the activity in the PD Trust with respect to ZAI PD Claims and other trust expenses. Through December 31, 2018, the PD Trust has paid approximately $15 million in ZAI PD Claims, approximately $6 million in operating and education expenses, and approximately $15 million in one-time attorneys’ fees. The trust balance was approximately $30 million as of December 31, 2018. We expect ZAI PD Claims payments to decline over time, but we have limited information to estimate the amount and timing of future claims payments. It is reasonably possible that we will make one or more contingent deferred payments. We estimate the present value of reasonably possible future payments to range between $0 million and $20 million. We have not accrued for any contingent deferred payments as we do not includebelieve that payment is probable. We will continue to evaluate new information as it becomes available and will revise our estimate of the cost to remediate the Libby vermiculite mineamount and surrounding area or costs related totiming of future claims payments and any additional EPA claims, whether resulting from the EPA's investigation of vermiculite facilities or otherwise, which may be material butcontingent deferred payments at that time. We are not currently estimable. Dueobligated to these vermiculite-related matters, itmake additional payments to the PD Trust in

Table of Contents

respect of ZAI PD Claims beyond the payments described above. We have satisfied all of our financial obligations with respect to Canadian ZAI PD Claims.
Unresolved and future Other PD Claims are to be litigated pursuant to procedures approved by the Bankruptcy Court and, to the extent such Other PD Claims are determined to be allowed claims, are to be paid in cash by the PD Trust. We are obligated to make a payment to the PD Account every six months in the amount of any Other PD Claims allowed during the preceding six months plus interest (if any) and the amount of PD Account expenses for the preceding six months (the “PD Obligation”). The aggregate amount we are required to pay under the PD Obligation is probable that our ultimate liability for environmental matters will exceed our current estimates by material amounts.not capped so we may have to make additional payments to the PD Account in respect of the PD Obligation.
Our indebtedness may materially affect our business, including our ability to fulfill our obligations, react to changes in our business and incur additional debt to fund future needs.
We have a substantial amount of debt. As of December 31, 2016,2018, we had $1,028.2$1,040.9 million of unsecured indebtedness outstanding and $555.9$942.4 million of secured indebtedness outstanding. Our indebtedness may have material effects on our business, including to:
require us to dedicate a substantial portion of our cash flow to debt payments, thereby reducing funds available for working capital, capital expenditures, acquisitions, research and development, distributions to stockholders, stockshareholders (which fall within the discretion of our Board of Directors taking into account financial, liquidity and other considerations), share repurchase programs and other purposes;
restrict us from making strategic acquisitions or taking advantage of favorable business opportunities;
limit our flexibility in planning for, or reacting to, changes in our business and the industries in which we operate;
increase our vulnerability to adverse economic, credit and industry conditions, including recessions;
make it more difficult for us to satisfy our debt service and other obligations;
place us at a competitive disadvantage compared to our competitors that have relatively less debt; and
limit our ability to borrow additional funds, or to dispose of assets to raise funds, if needed, for working capital, capital expenditures, acquisitions, research and development and other purposes.
If we incur additional debt, the risks related to our indebtedness may intensify.
Restrictions imposed by agreements governing our indebtedness may limit our ability to operate our business, finance our future operations or capital needs, or engage in other business activities. If we fail to comply with certain restrictions under these agreements, our debt could be accelerated and we may not have sufficient cash to pay our accelerated debt.
The agreements governing our indebtedness contain various covenants that limit, among other things, our ability, and the ability of certain of our subsidiaries, to:
incur certain liens;
enter into sale and leaseback transactions; and
consolidate, merge or sell all or substantially all of our assets or the assets of our guarantors.
As a result of these covenants, we will be limited in the manner in which we can conduct our business, and may be unable to engage in favorable business activities or finance future operations or capital needs. Accordingly, these restrictions may limit our flexibility to operate our business. A failure to comply with the restrictions contained in these agreements, including maintaining the financial ratios required by our credit facilities, could lead to an event of default which could result in an acceleration of our indebtedness. We cannot assure you that our future operating results will be sufficient to enable us to comply with the covenants contained in the agreements governing our indebtedness or to remedy any such default. In addition, in the event of an acceleration, we may not have or be able to obtain sufficient funds to make any accelerated payments.
Our indebtedness exposes us to interest expense increases if interest rates increase.
As of December 31, 2016, $313.02018, approximately $297.2 million or approximately 20%, of our borrowings were at variable interest rates and expose us to interest rate risk.risk, excluding $598.5 million hedged by cross-currency swaps effective in November 2018, and $100.0 million hedged by interest rate swaps effective in April 2018. If interest rates increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed would

Table of Contents

remain the same, and our net income would decrease. An increase of 100 basis points in the interest rates payable on our variable rate indebtedness would increase our annual estimated debt-service requirements by $3.1$3.0 million, assuming our consolidated variable interest rate indebtedness outstanding as of December 31, 2016,2018, remains the same.

Table of Contents

We have unfunded and underfunded pension plan liabilities. We will require future operating cash flow to fund these liabilities. We have no assurance that we will generate sufficient cash to satisfy these obligations.
We maintain U.S. and non-U.S. defined benefit pension plans covering current and former employees who meet or met age and service requirements. Our net pension liability and cost is materially affected by the discount rate used to measure pension obligations, the longevity and actuarial profile of our workforce, the level of plan assets available to fund those obligations and the actual and expected long-term rate of return on plan assets. Significant changes in investment performance or a change in the portfolio mix of invested assets can result in corresponding increases and decreases in the valuation of plan assets or in a change in the expected rate of return on plan assets. Assets available to fund the pension benefit obligation of the U.S. advance-funded pension plans at December 31, 2016,2018, were approximately $1,086$833 million, or approximately $82$65 million less than the measured pension benefit obligation on a U.S. GAAP basis. In addition, any changes in the discount rate could result in a significant increase or decrease in the valuation of pension obligations, affecting the reported funded status of our pension plans as well as the net periodic pension cost in the following years. Similarly, changes in the expected return on plan assets can result in significant changes in the net periodic pension cost in the following years.
Our obligation to make payments to the PD Trust in respect of asbestos PD Claims (other than ZAI PD Claims) is not cappedand we may be obligated to make additional payments.
Under the Joint Plan of reorganization that concluded Grace's status as a debtor under Chapter 11, as discussed above (the "Joint Plan"), an asbestos property damage trust has been established and funded under Section 524(g) of the Bankruptcy Code. The order of the Bankruptcy Court confirming the Joint Plan contains a channeling injunction which provides that all pending and future asbestos-related property damage claims and demands, PD Claims, can only be brought against the PD Trust. The PD Trust contains two accounts. One of these accounts, the PD Account, is funded solely in respect of PD Claims other than those PD Claims related to our former ZAI attic insulation product. Unresolved and future non-ZAI PD Claims are to be litigated pursuant to procedures approved by the Bankruptcy Court and, to the extent such PD claims are determined to be allowed claims, are to be paid in cash by the PD Trust. We are obligated to make a payment to the PD Trust every six months in the amount of any non-ZAI PD Claims allowed during the preceding six months plus interest (if any) and the amount of PD Trust expenses for the preceding six months (the "PD Obligation"). The aggregate amount we are required to pay under the PD Obligation is not capped so we may have to make additional payments to the PD Account in respect of the PD Obligation. We are also obligated to make up to 10 contingent deferred payments to the PD Trust of $8 million each during the 20-year period beginning February 3, 2019, in respect of ZAI PD Claims in the event the ZAI PD Account's assets fall below $10 million in the preceding year. We have accrued liabilities for probable PD Claims but have not accrued any liability for the contingent ZAI PD payments as we do not believe they are probable.

Our ability to use net operating losses and tax credits to reduce future tax payments may be limited if there is a change in ownership of Grace or if Grace does not generate sufficient U.S. taxable income or foreign source income. Our ability to use these attributes is also subject to time limitations. Changes in tax laws and regulations may reduce their value and availability.
Our ability to use future tax deductions and tax credits, including net operating losses ("NOLs"(“NOLs”), is dependent on our ability to generate sufficient future taxable income in the U.S. and sufficient foreign source income. Under U.S. federal income tax law, a corporation is generally permitted to carry forward NOLs for a 20-year period (indefinitely in the case of NOLs occurring in taxable years after December 31, 2017) for deduction against future taxable income. Federal tax credits may be carried forward for 10 years. Also, our ability to use NOLs and tax credits and their value may be adversely affected by changes in tax laws and regulations.
In addition, our ability to use futureutilize federal and state NOLs and U.S. federal tax deductionscredits may be limited by Section 382 of the Internal Revenue Code resulting from future changes in the ownership of outstanding Company common stock. Our Amended and Restated Certificate of Incorporation provides that under certain circumstances, our Board of Directors would have the authority to impose restrictions on the transfer of Company common stock with respect to certain 5% stockholders in order to preserve these future tax deductions.
Under U.S. federal income tax law, a corporation is generally permitted to carry forward NOLs for a 20-year period for deduction against future taxable income. Foreign tax credits also expire over time. Also, our ability to use NOLs and tax credits and their value may be adversely affected by changes in tax laws and regulations.
We intend to pursue acquisitions, joint ventures and other transactions that complement or expand our businesses. We may not be able to complete proposed transactions and even if completed, the transactions may involve a number of risks that may materially and adversely affect our business, financial condition and results of operations.
We intend to continue to pursue opportunities to buy other businesses or technologies that could complement, enhance or expand our current businesses or product lines or that might otherwise offer us growth opportunities. We may have difficulty identifying appropriate opportunities or, if we do identify opportunities, we may not be successful in completing transactions for a number of reasons. Any transactions that we are able to identify and complete may involve a number of risks, including:
the diversion of management'smanagement’s attention from our existing businesses to integrate the operations and personnel of the acquired or combined business or joint venture;
possible adverse effects on our operating results during the integration process;
failure of the acquired business to achieve expected operational objectives;
possible assumption of unexpected liabilities;
inability to obtain indemnification from other parties to transactions; and
our possible inability to achieve the intended objectives of the transaction.

In addition, we may not be able to successfully or profitably integrate, operate, maintain and manage any newly acquired operations or their employees. We may not be able to maintain uniform standards, controls, procedures and policies, which may lead to operational inefficiencies.
We work with dangerous materials that can injure our employees, damage our facilities, and disrupt our operations.operations, and contaminate the environment.
Some of our operations involve the handling of hazardous materials that may pose the risk of fire, explosion, or the release of hazardous substances. Such events could result from natural disasters, operational failures or terrorist attacks, and might cause injury or loss of life to our employees and others, environmental contamination, and property damage. These events might cause a temporary shutdown of an affected plant, or portion thereof, and we could be subject to penalties or claims as a result.result of any of these events. A disruption of our operations caused by these or other events could have a material adverse effect on our results of operations.
Some of our employees are unionized, represented by works councils or employed subject to local laws that are less favorable to employers than the laws in the United States.
As of December 31, 2016,2018, we had approximately 3,7003,900 global employees. Approximately 630700 of our approximately 1,9002,100 U.S. employees are unionized.unionized at 5 manufacturing sites. In addition, a large number of our employees are employed in countries in which employment laws provide greater bargaining or other rights to employees than the laws in the United States. Such employment rights require us to work collaboratively with the legal representatives of the employees to effect any changes to labor arrangements. For example, most of our employees in Europe are represented by works councils that have co-determination rights on any changes in conditions of employment, including certain salaries and benefits and staff changes, and may impede efforts to restructure our workforce. A strike, work stoppage or slowdown by our employees or significant dispute with our employees, whether or not related to these negotiations, could result in a significant disruption of our operations or higher ongoing labor costs.

Table of Contents

We may be subject to claims of infringement of the intellectual property rights of others, which could hurt our business.
From time to time, we face infringement claims from our competitors or others alleging that our processes or products infringe on their proprietary technologies. Any claims that our products or processes infringe the intellectual property rights of others, regardless of the merit or resolution of the claims, could cause us to incur significant costs in responding to, defending and resolving the claims, and may divert the efforts and attention of our management and technical personnel from our business. If we are found to be infringing on the proprietary technology of others, we may be liable for damages, and we may be required to change our processes, redesign our products, pay others to use the technology, or stop using the technology or producing the infringing product. Even if we ultimately prevail, the existence of the lawsuit could prompt our customers to switch to products that are not the subject of infringement suits.
We are subject to business continuity risks that may adversely affect our business, financial condition and results of operations.
We are subject to significant risks from both natural disasters and accidents such as fires, storms, and floods, and other disruptive events, such as war, insurrection, and terrorist actions. These types of occurrences can negatively affect our manufacturing, supply chain, logistics, transportation, information technology, and communications functions. Similarly, they can strike major suppliers and customers, thus restricting or delaying our supply of raw materials or energy as well as reducing or deferring demand for our products and services. Also, we have centralized certain administrative functions, primarily in North America, Europe and Asia, to improve efficiency and reduce costs. To the extent that these central locations are disrupted or disabled, key business processes, such as invoicing, payments and general management operations, could be interrupted.
As we operate worldwide in a competitive environment, global economic and financial market conditions may adversely affect our business, financial condition and results of operations.
We compete by selling value-added products, technologies and services. Increased levels and numbers of competitors, globally or regionally, could negatively impact our results of operations. Economic conditions around the world can have a direct impact on our revenues. A global or regional economic downturn or market uncertainty could reduce the demand for our products, technologies and services, which could negatively impact our results

Table of Contents

of operations. Since many of our customers are refiners, our fluid catalytic cracking (FCC) catalyst business is highly dependent on the economics of the petroleum refining industry. Demand for our FCC products is affected by refinery throughput, the type and quality of refinery feedstocks, and the demand for transportation fuels and other refinery products, such as propylene. Also, disruptions in the financial markets could have an adverse effect on our ability to finance our operations and growth plans, and could negatively impact our suppliers and customers in similar manners.
Our ability to operate our businesses and our financial condition could be significantly undermined by cybersecurity breaches.
Despite our implementation of security measures, our information technology (“IT”) systems are subject to cyber attackcyberattack and other similar disruptions. Breaches by hackers, the introduction of computer viruses and other cybersecurity incidents affecting our IT systems could result in disruptions to our operations. Also, such incidents could include theft of our trade secrets and other intellectual property, as well as confidential customer, employee and business information, which could be used by unauthorized parties and publicly disclosed. This could negatively affect our relationships with customers and our ability to compete effectively, and could ultimately harm our reputation, business, financial condition and results of operations. In addition, we may be required to incur significant costs to protect against damage caused by cybersecurity breaches in the future.
A failure of our information technology infrastructure could adversely impact our business and operations.
We rely upon the capacity, reliability and security of our IT infrastructure and our ability to expand and continually update this infrastructure in response to the changing needs of our business. If we experience a problem with the functioning of an important IT system, the resulting disruptions could have an adverse effect on our business. Our IT systems affect virtually every aspect of our business, including supply chain, manufacturing, logistics, finance and communications. We and certain of our third-party vendors receive and store personal

Table of Contents

information in connection with our human resources operations and other aspects of our business. Any IT system failure, natural disaster, accident, or intentional breach could result in disruptions to our operations.
Risks Related to the Separation
Grace and GCP are subject to restrictions under a Tax Sharing Agreement between them, and a violation of the Tax Sharing Agreement may result in tax liability to Grace and its stockholders.
We entered into a Tax Sharing Agreement with GCP to preserve the tax-free treatment, for U.S. federal income tax purposes, of the separation and distribution of GCP common stock to Grace stockholders. Under this Tax Sharing Agreement, we and GCP will be restricted from engaging in certain transactions that could result in the Separation becoming taxable to us and our stockholders. Compliance with the Tax Sharing Agreement and the restrictions therein may limit our near-term ability to pursue certain strategic transactions or engage in activities that might be beneficial from a business perspective. This may result in missed opportunities or the pursuit of business strategies that may not be as beneficial for us and which may negatively affect our anticipated profitability. If GCP fails to comply with the restrictions in the Tax Sharing Agreement and as a result the Separation was determined to be taxable for U.S. federal income tax purposes, we and our stockholders at the time of the Separation that are subject to U.S. federal income tax could incur significant U.S. federal income tax liabilities. Although the Tax Sharing Agreement provides that GCP is required to indemnify us for taxes incurred that may arise were GCP to fail to comply with its obligations under the Tax Sharing Agreement, there is no assurance that GCP will have the funds to satisfy that liability. Also, GCP will not be required to indemnify our stockholders for any tax liabilities they may incur for its violation of the Tax Sharing Agreement.
In connection with the Separation, GCP will indemnify us and we will indemnify GCP for certain liabilities. There can be no assurance that the indemnities from GCP will be sufficient to insure us against the full amount of such liabilities, or that GCP’s ability to satisfy its indemnification obligation will not be impaired in the future.
Pursuant to the Separation and Distribution Agreement and other agreements we entered into in connection with the Separation, GCP agreed to indemnify us for certain liabilities, and we agreed to indemnify GCP for certain liabilities. However, third parties might seek to hold us responsible for liabilities that GCP agreed to assume or retain under these agreements, and there can be no assurance that GCP will be able to fully satisfy its indemnification obligations under these agreements.
A court could deem the Distribution in the Separation to be a fraudulent conveyance and void the transaction or impose substantial liabilities upon us.
If the transaction is challenged by a third party, notwithstanding the fact that we received an opinion from a nationally recognized financial firm that we were solvent and had adequate surplus to make the Distribution, a court could deem the distribution of GCP common stock or certain internal restructuring transactions undertaken by us in connection with the Separation to be a fraudulent conveyance or transfer. Fraudulent conveyances or transfers are defined to include transfers made or obligations incurred with the actual intent to hinder, delay or defraud current or future creditors or transfers made or obligations incurred for less than reasonably equivalent value when the debtor was insolvent, or that rendered the debtor insolvent, inadequately capitalized or unable to pay its debts as they become due. In such circumstances, a court could void the transactions or impose substantial liabilities upon us, which could adversely affect our financial condition and our results of operations. Among other things, the court could require our stockholders to return to us some or all of the shares of GCP common stock issued in the Distribution or require us to fund liabilities of other companies involved in the Separation for the benefit of creditors. Whether a transaction is a fraudulent conveyance or transfer will vary depending upon the laws of the applicable jurisdiction.

Item 5.    MARKET FOR REGISTRANT'SREGISTRANT’S COMMON EQUITY, RELATED SHAREHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES
Except as provided below, the disclosure required by this Item appears in this Report in: Item 6 (Selected Financial Data); under the heading "Selected“Selected Financial Data"Data” opposite the caption "Other“Other Statistics—Common shareholders of record"record” in the Financial Supplement; Item 8 (Financial Statements and Supplementary Information) in the Financial Supplement in Note 14 (Shareholders'(Shareholders’ Equity) and Note 22 (Quarterly Summary and StatisticalFinancial Information (Unaudited)) opposite the captions "Dividendscaption “Dividends declared per share" and "Market price of common stock")share” to the Consolidated Financial Statements; and Item 12 (Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters), and such disclosure is incorporated herein by reference.
SHAREHOLDER RIGHTS AGREEMENTCOMPANY COMMON STOCK
On March 31, 1998, we paid a dividend of one Preferred Stock Purchase Right on each share of Company common stock. Subject to our prior redemptionThe principal market for $.01 per right, rights will become exercisable on the earlier of:
10 days after an acquiring person, composed of an individual or group, has acquired beneficial ownership of 20% or more of the outstanding Company common stock or
10 business days (or a later date fixed byis the Board of Directors) after an acquiring person commences (or announcesNew York Stock Exchange, under the intention to commence) a tender offer or exchange offer for beneficial ownership of 20% or more of the outstanding Company common stock.symbol GRA.
Until these events occur, the rights will automatically trade with the Company common stock, and separate certificates for the rights will not be distributed. The rights do not have voting or dividend rights.
Generally, each right not owned by an acquiring person:
will initially entitle the holder to buy from Grace one hundredth of a share of the Company Junior Participating Preferred Stock, at an exercise price of $100, subject to adjustment;
will entitle such holder to receive upon exercise, in lieu of shares of Company junior preferred stock, that number of shares of Company common stock having a market value of two times the exercise price of the right; and
may be exchanged by Grace for one share of Company common stock or one hundredth of a share of Company junior preferred stock, subject to adjustment.
Generally, if there is an acquiring person and we are acquired, each right not owned by an acquiring person will entitle the holder to buy a number of shares of common stock of the acquiring company having a market value equal to twice the exercise price of the right.
Each share of Company junior preferred stock will be entitled to a minimum preferential quarterly dividend payment of $1.00 per share but will be entitled to an aggregate dividend equal to 100 times the dividend declared per share of Company common stock whenever such dividend is declared. In the event of liquidation, holders of Company junior preferred stock will be entitled to a minimum preferential liquidation payment of $100 per share but will be entitled to an aggregate payment equal to 100 times the payment made per share of Company common stock. Each share of Company junior preferred stock will have 100 votes, voting together with the Company common stock. Finally, in the event of any business combination, each share of Company junior preferred stock will be entitled to receive an amount equal to 100 times the amount received per share of Company common stock. These rights are protected by customary antidilution provisions.
The terms of the rights may be amended by the Board of Directors without the consent of the holders of the rights. The rights expire on March 30, 2018. The rights have been approved by the U.S. Bankruptcy Court for the District of Delaware and the Official Committee of Equity Security Holders in connection with our Chapter 11 proceedings.

This summary of the rights does not purport to be complete and is qualified in its entirety by reference to the Rights Agreement, which has been filed with the SEC.
DIVIDENDS ON COMPANY COMMON STOCK
Prior to 2016, we had not paid a cash dividend on Company common stock since 1997. However, on January 26, 2016,On February 7, 2019, we announced that ourthe Board of Directors approved a policy of paying a regular quarterly cash dividend at an initial annual rate of $0.68 per share of Company common stock. On February 8, 2017, we announced that our Board of Directorshad approved an increase to the annual cash dividend rate, raising itfrom $0.96 to $0.84$1.08 per share of Company common stock. Grace expects to continue growing our dividend as part of our disciplined capital allocation strategy.
Although our credit agreement and indentures (as described in Item 8 (Financial Statements and Supplementary Data) in the Financial Supplement under Note 5 (Debt) to the Consolidated Financial Statements and filed as an exhibit to this Report) contain certain restrictions on the payment of dividends on, and redemptions of, equity interests and other restricted payments, we believe that such restrictions do not currently materially limit our ability to pay dividends. Any determination to pay cash dividends in the future may be affected by business and market conditions, our views on potential future capital requirements, the restrictions noted above, covenants contained in any agreements we may enter into in the future and changes in federal income tax law.
SHARE REPURCHASES
Share Repurchase Program
On February 5, 2015, we announced that the Board of Directors authorized a share repurchase program of up to $500 million.million, which we completed on July 10, 2017. On February 8, 2017, we announced that the Board of Directors authorized an additional share repurchase program of up to $250 million. Repurchases under the programprograms may be made through one or more open market transactions at prevailing market prices; unsolicited or solicited privately negotiated transactions; accelerated share repurchase programs; or through any combination of the foregoing, or in such other manner as determined by management. The timing of the repurchases and the actual amount repurchased will depend on a variety of factors, including the market price of Grace'sGrace’s shares, the strategic deployment of capital, and general market and economic conditions.
The following table presents information regarding the repurchasestatus of repurchases of Company common stock by or on behalf of Grace or any "affiliated purchaser"“affiliated purchaser” of Grace during the three months ended December 31, 2016:Grace.

PI Warrant Settlement
As of February 3, 2014, the effective date of the Grace Joint Plan of Reorganization, we issued to the WRG Personal Injury Trust warrants (the "PI Warrant") to acquire 10 million shares of Company common stock at a price of $17 per share. On February 3, 2015, we repurchased the PI Warrant for a payment of $490 million.
STOCK TRANSFER RESTRICTIONS
Under the terms of our Amended and Restated Certificate of Incorporation, as approved by the Bankruptcy Court as part of the confirmation of the Joint Plan, in order to preserve significant tax benefits which are subject to elimination or limitation, the Board of Directors has the authority to impose restrictions on the transfer of Company common stock with respect to certain 5% shareholders. Imposing such restrictions requires at least a 25% ownership shift to occur (as determined under Internal Revenue Code regulations) and at least a two-thirds vote of all of the directors. These restrictions would generally not limit the ability of a person that holds less than 5% of Company common stock to either buy or sell stock on the open market.

The disclosure required by this Item appears in the Financial Supplement under the heading "Management's“Management’s Discussion and Analysis of Financial Condition and Results of Operations"Operations” which disclosure is incorporated herein by reference.
Item 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Our global operations, raw materials and energy requirements, and debt obligations expose us to various market risks. We use derivative financial instruments to mitigate certain of these risks. The following is a discussion of our primary market risk exposures, how those exposures are managed, and certain quantitative data pertaining to our market risk-sensitive instruments.
Currency Exchange Rate Risk
We operate and/or sell to customers in over 6070 countries and in over 30 currencies; therefore, our results of operations are exposed to changes in currency exchange rates. We seek to minimize exposure to these changes by matching revenue streams in volatile currencies with expenditures in the same currencies, but it is not always possible to do so. Further, where revenue streams exceed expenditures in a given currency, we seek opportunities to invoice our customers in U.S. dollars or peg the revenue stream to the U.S. dollar at the time of the sale. From time to time, we use financial instruments such as currency forward contracts, swaps, options, or combinations of them to reduce the risk of certain specific transactions. However, we do not have a policy of hedging all exposures, because management does not believe that such a level of hedging would be cost-effective. Significant uses of derivatives to mitigate the effects of changes in currency exchange rates are as follows.
In May 2016, Grace entered into a fixed-to-fixed cross-currency swap maturing in October 2021 to hedge its net investment in non-U.S. subsidiaries. On every April 1 and October 1, Grace will swap interest payments. Grace will pay euro fixed at the annual rate of 3.426% on €170.0 million and receive U.S. dollars fixed at the annual rate of 5.125% on $190.3 million. The agreement requires an exchange of the notional amounts at maturity. The following tables provide information about the cross-currency swap at December 31, 2016,2018, specifically, the aggregate future cash flows for each of the five next three years and thereafter and the fair value. The fair value represents the value of the derivative contract, and is included in "other“other current assets"assets” and "other assets"“other liabilities” in the Consolidated Balance Sheets.

In April 2018, in connection with the Credit Agreement (see Note 5), Grace entered into new cross-currency swaps beginning on April 3, 2018, and maturing on March 31, 2023, to synthetically convert $600.0 million of U.S. dollar-denominated floating rate debt into €490.1 million of euro-denominated debt fixed at 2.0231%. These cross-currency swaps were de-designated and terminated on November 5, 2018, and replaced with new, at-market cross-currency swaps beginning on November 5, 2018, and maturing on March 31, 2023, to synthetically convert $600.0 million of U.S. dollar-denominated floating rate debt into €525.9 million of euro-denominated debt fixed at 1.785%. The agreements require partial exchanges of the notional amounts each quarter and the remaining amounts at maturity. The following tables provide information about the cross-currency swaps at December 31, 2018, specifically, the aggregate future cash flows for each of the next five years and the fair value. The fair value represents the value of the derivative contracts, and is included in “other current assets” and “other liabilities” in the Consolidated Balance Sheets.

Commodity Price Risk
We operate in markets where the prices of raw materials and energy are commonly affected by cyclical movements in the economy and other factors. The principal raw materials used in our products include molybdenum oxide, sodium silicate, zeolite, caustic soda, sodium aluminate, aluminum sulfate, rare earths, alumina, aluminum metal and tungsten salt. Natural gas is the largest single energy source that we purchase. These commodities are generally available to be purchased from more than one supplier. In order to minimize the

Table of Contents

risk of increasing prices on certain raw materials and energy, we use a centralized supply chain organization for sourcing in order to optimize procurement activities. We have a risk management committee to review proposals to hedge purchases of raw materials and energy.
We have implemented a risk management program under which we hedge natural gas and aluminum supply in a way that seeks to provide protection against price volatility in the natural gas and aluminum markets. In order to mitigate volatility in natural gas prices, we have entered into both fixed-rate swaps and options contracts to hedge a portion of our U.S. natural gas requirements. Additionally, in order to mitigate volatility in aluminum prices, we have entered into fixed-rate swaps to hedge a portion of our U.S. aluminum requirements.
The following tables provide information about our commodity fixed-rate swaps. For natural gas commodity fixed-rate swaps, contract volumes, or notional amounts, are presented in millions of MMBtu (million British thermal units), weighted average contract prices are presented in U.S. dollars per million MMBtu, and the total contract amount and fair value are presented in millions of U.S. dollars. For aluminum commodity fixed-rate swaps, contract volumes, or notional amounts, are presented in millions of pounds, weighted average contract prices are presented in U.S. dollars per pound, and the total contract amount and fair value are presented in millions of U.S. dollars. The fair values of the commodity fixed-rate swaps represent the excess of the variable price (market price) over the fixed price (pay price) multiplied by the nominal contract volumes. All commodity fixed-rate swaps mature within 15 months.

The fair value of commodity derivative contracts is presented as other assets or other liabilities and allocated between current and non-current, as appropriate, in the Consolidated Balance Sheets.
We have also entered into forward contracts for natural gas and aluminum that qualify for the normal purchases and normal sales exception from Accounting Standards Codification ("ASC") 815 "Derivatives and Hedging," as they do not contain net settlement provisions and therefore result in physical delivery of natural gas and aluminum from suppliers. Accordingly, the fair values of these contracts are not recorded in our Consolidated Balance Sheets.
Interest Rate Risk
As of December 31, 2016,2018, approximately $313.0$297.2 million of our borrowings were at variable interest rates and expose us to interest rate risk.risk, excluding $598.5 million hedged by cross-currency swaps effective in November 2018, and $100.0 million hedged by interest rate swaps effective in April 2018. As a result, we have been and will continue to be subject to the variations on interest rates in respect of our floating-rate debt. A 100 basis point increase in the interest rates payable on our variable rate debt outstanding as of December 31, 2016,2018, would increase our annual interest expense by approximately $3.1$3.0 million.
In connection with our emergence financing, wethe Credit Agreement (see Note 5), Grace entered into annew interest rate swapswaps beginning on FebruaryApril 3, 2015,2018, and maturing on February 3, 2020,March 31, 2023, fixing the LIBOR component of the interest on $250$100.0 million of Grace's term debt at a rate of 2.393%2.775%. While we have and may continue to enter into agreements intending to limit our exposure to higher interest rates, any such agreements may not offer complete protection from this risk.

Financial statements of less than majority-owned persons and other persons accounted for by the equity method have been omitted as provided in Rule 3-09 of the United States Securities and Exchange Commission's (SEC)Commission’s (the “SEC”) Regulation S-X.

Management'sManagement’s Report on Internal Control Over Financial Information and Internal ControlsReporting
Responsibility For Financial InformationWe areI am responsible for the preparation, accuracy, integrity and objectivity of the Consolidated Financial Statements and the other financial information included in this report. Such information has been prepared in conformity with accounting principles generally accepted in the United States of America and accordingly, includes certain amounts that represent management'smanagement’s best estimates and judgments. Actual amounts could differ from those estimates.
Responsibility For Internal ControlsWeI and ourGrace’s management are also responsible for establishing and maintaining adequate internal controls over financial reporting. These internal controls consist of policies and procedures that are designed to assess and monitor the effectiveness of the control environment including risk identification, governance structure, delegations of authority, information flow, communications and control activities. A chartered Disclosure Committee oversees Grace'sGrace’s public financial reporting process and key managers are required to confirm their compliance with Grace'sGrace’s policies and internal controls quarterly. While no system of internal controls can ensure elimination of all errors and irregularities, Grace'sGrace’s internal controls, which are reviewed and modified in response to changing conditions, have been designed to provide reasonable assurance that assets are safeguarded, policies and procedures are followed, transactions are properly executed and reported, and appropriate disclosures are made. The concept of reasonable assurance is based on the recognition that there are limitations in all systems of internal control and that the costs of such systems should be balanced with their benefits. The Audit Committee of the Board of Directors, which is composed solely of independent directors, meets regularly with Grace'sGrace’s senior financial management, internal auditors and independent registered public accounting firm to review audit plans and results, as well as the actions taken by management in discharging its responsibilities for accounting, financial reporting and internal controls. The Audit Committee is responsible for the selection and compensation of the independent registered public accounting firm. Grace'sGrace’s financial management, internal auditors and independent registered public accounting firm have direct and confidential access to the Audit Committee at all times.
Report On Internal Control Over Financial ReportingWeI and ourGrace’s management have evaluated Grace'sGrace’s internal control over financial reporting as of December 31, 20162018. This evaluation was based on criteria for effective internal control over financial reporting set forth in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, weI and ourGrace’s management have concluded that Grace'sGrace’s internal control over financial reporting is effective as of December 31, 20162018. Grace'sGrace’s independent registered public accounting firm that audited our financial statements included in Item 15 has also audited the effectiveness of Grace'sGrace’s internal control over financial reporting as of December 31, 20162018, as stated in their report, which appears on the following page.
Report On Disclosure Controls And Procedures—As of December 31, 20162018, weI and ourGrace’s management carried out an evaluation of the effectiveness of the design and operation of Grace'sGrace’s disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"“Exchange Act”). Based upon that evaluation, weI concluded that Grace'sGrace’s disclosure controls and procedures are effective in ensuring that information required to be disclosed in Grace'sGrace’s periodic filings and submissions under the Exchange Act is accumulated and communicated to usme and ourGrace’s management to allow timely decisions regarding required disclosures, and such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission'sCommission’s rules and forms.

To theShareholders and Board of Directors of W. R. Grace & Co.:

Grace & Co. and its subsidiaries (the “Company”) as of December 31, 2018 and 2017, and the related consolidated statements of operations, of comprehensive income (loss), of equity, and of cash flows present fairly, in all material respects, the financial position of W. R. Grace & Co. and its subsidiaries(the “Company”) atDecember 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period endedDecember 31, 2016 2018, including the related notes and schedule of valuation and qualifying accounts and reserves for each of the three years in the period ended December 31, 2018 appearing under Item 15 (collectively referred to as the “consolidated financial statements”).We also have audited the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework(2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of itsoperations and itscash flows for each of the three years in the period ended December 31, 2018in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the accompanying financial statement schedule presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016,2018, based on criteria established in Internal Control - Integrated Framework(2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, and financial statement schedule, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanyingManagement's Management’s Report on Internal Control Over Financial Information and Internal Controls.Reporting. Our responsibility is to express opinions on thesethe Company’s consolidated financial statements on the financial statement schedule, and on the Company's internal control over financial reporting based on our integrated audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence supportingregarding the amounts and disclosures in the consolidated financial statements, assessingstatements. Our audits also included evaluating the accounting principles used and significant estimates made by management, andas well as evaluating the overall presentation of the consolidated financial statement presentation.statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note 1 to the consolidated financial statements, the Company changed the manner in which it accounts for debt issuance costsDefinition and the manner in which it accounts for stock compensation in 2016.Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in


accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Separation Transaction    On January 27, 2016, Grace entered into a separation agreement with GCP Applied Technologies Inc., then a wholly-owned subsidiary of Grace ("GCP"(“GCP”), pursuant to which Grace agreed to transfer its Grace Construction Products operating segment and the packaging technologies business of its Grace Materials Technologies operating segment to GCP (the "Separation"“Separation”). Grace and GCP completed the Separation on February 3, 2016 (the "Distribution Date"“Distribution Date”), by means of a pro rata distribution to the Company's stockholdersCompany’s shareholders of all of the outstanding shares of GCP common stock (the "Distribution"“Distribution”), with one share of GCP common stock distributed for each share of Company common stock held as of the close of business on January 27, 2016. As a result of the Distribution, GCP became an independent public company. GCP’s historical financial results through the Distribution Date are reflected in Grace’s Consolidated Financial Statements as discontinued operations.
Chapter 11 Proceedings    On April 2, 2001, Grace and 61 of its United States subsidiaries and affiliates filed voluntary petitions for reorganization under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware (the "Bankruptcy Court") in order to resolve outstanding asbestos personal injury and property damage claims, including class-action lawsuits alleging damages from Zonolite® Attic Insulation ("ZAI"), a former Grace attic insulation product. In 2008, Grace and other parties filed a joint plan of reorganization with the Bankruptcy Court (as subsequently amended, the "Joint Plan"). Following the confirmation of the Joint Plan in 2011 by the Bankruptcy Court and in 2012 by a U.S. District Court, and the resolution of all appeals, Grace emerged from bankruptcy on February 3, 2014.
Principles of Consolidation    The Consolidated Financial Statements include the accounts of Grace and entities as to which Grace maintains a controlling financial interest. Intercompany transactions and balances are eliminated in consolidation. Investments in affiliated companies in which Grace can significantly influence operating and financial policies, but does not have a controlling financial interest, are accounted for under the equity method.
Grace conducts certain of its business through joint ventures with unaffiliated third parties. For joint ventures in which Grace has a controlling financial interest, Grace consolidates the results of such joint ventures in the Consolidated Financial Statements. Grace recognizes a liability for cumulative amounts due to the third parties based on the financial results of the joint ventures, and deducts the amount of income attributable to noncontrolling interests in the measurement of its consolidated net income.
Reportable Segments    Grace reports financial results of each of its reportable segments that engage in business activities that generate revenues and expenses and whose operating results are regularly reviewed by Grace'sGrace’s Chief Executive Officer and Chief Operating Officer.
Use of Estimates    The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("(“U.S. GAAP"GAAP”) requires management to make estimates and assumptions that affect the reported amountamounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements, and the reported amounts of revenues and expenses for the periods presented. Actual amounts could differ from those estimates, and the differences could be material. Changes in estimates are recorded in the period identified. Grace'sGrace’s accounting measurements that are most affected by management'smanagement’s estimates of future events are:

Contingent liabilities, which depend on an assessment of the probability of loss and an estimate of ultimate obligation, such as litigation (see Note 10), income taxes (see Note 7), and environmental remediation (see Note 10).
Revenue Recognition    Grace recognizesgenerates revenues predominantly from sales of manufactured products to customers and in part from licensing of technology. Under ASC 606, revenue from customer arrangements is recognized when allcontrol is transferred to the customer.
Product Sales
In its implementation of ASC 606, Grace assessed its customer arrangements at the operating segment level, and based on the similarity of arrangements, Grace elected to use the portfolio method practical expedient. Based on the promises made to customers in product sales arrangements, Grace determined that it has a performance obligation to manufacture and deliver products to its customers. Grace makes certain other promises in its customer arrangements that are immaterial in the context of the following criteria are satisfied: risk of loss and title transfercontracts. Revenue is recognized at amounts based on agreed-upon prices in sales contracts and/or purchase orders. Grace offers various incentives to the customer;its product sales customers that result in variable consideration, including but not limited to volume discounts, which reward bulk purchases by lowering the price for future purchases, and volume rebates, which encourage customers to purchase volume levels that would reduce their current prices. These incentives are immaterial in the context of the contracts.
For product sales, control is fixed and determinable; persuasive evidence of a sales arrangement exists; and collectability is reasonably assured. Thetransferred at the point in time at which risk of loss and title transfershave transferred to athe customer, which is determined based on shipping terms. Terms of delivery and terms whichof payment are generally included in customer contracts of sale, order confirmation documents, and invoices. Payment is generally due within 30 to 60 days of invoicing. Grace defers revenue recognition until no other significant Grace performance obligations remain. Grace’s customer arrangements do not contain significant acceptance provisions.
Taxes that Grace collects that are assessed by a governmental authority, and that are both imposed on and concurrent with any of its revenue-producing activities, are excluded from revenue. Grace considers shipping and handling activities that it performs as activities to fulfill the sales of its products. Amounts billed for shipping and handling are included in net sales, while costs incurred for shipping and handling are included in cost of sales, in accordance with the practical expedient provided by ASC 606.
Technology Licensing
For Grace’s technology licensing business, Grace determined that the customer arrangements contain multiple deliverables to enable licensees to realize the full benefit of the technology. These deliverables include licensing the technology itself; developing engineering design packages; and providing training, consulting, and technical services. Under these arrangements, the license grant is not a distinct performance obligation, as the licensee only can benefit from the license in conjunction with other integral services such as development of the engineering design package, training, consulting, or technical services provided over the contract period. Therefore, Grace accounts for the license grant and integral services as a single performance obligation. Certain deliverables and services not included in the core bundled deliverables are accounted for as separate performance obligations.
The transaction price is specified in the technology licensing agreements and is substantially fixed. Some services are priced on a per-diem basis, but these are not material in the context of the contracts. Grace invoices its technology licensing customers as certain project milestones are achieved. Payment terms are similar to those of Grace’s product sales.
Revenue for each performance obligation is recognized when control is transferred to the customer, which is generally over a period of time. As a result, Grace generally recognizes revenue for each performance obligation ratably over the period of the contract, which is up to 7 years, depending on the scope of the licensee’s project. Based on the timing of payments, Grace records deferred revenue related to these agreements. See Note 17.

Cash Equivalents    Cash equivalents consist of liquid instruments and investments with maturities of three months or less when purchased. The recorded amounts approximate fair value.
Inventories    Inventories are stated at the lower of cost or market.net realizable value. The method used to determine cost is first-in/first-out, or "FIFO."“FIFO.” Market values for raw materials are based on current cost and, for other inventory classifications, net realizable value. Inventories are evaluated regularly for salability, and slow moving and/or obsolete items are adjusted to expected salable value. Inventory values include direct and certain indirect costs of materials and production. Abnormal costs of production are expensed as incurred.
Long Lived Assets    Properties and equipment are stated at cost. Depreciation of properties and equipment is generally computed using the straight-line method over the estimated useful life of the asset. Estimated useful lives range from 20 to 30 years for buildings, 3 to 7 years for information technology equipment, 35 to 1025 years for operating machinery and equipment, and 5 to 10 years for furniture and fixtures. Interest is capitalized in connection with major project expenditures. Fully depreciated assets are retained in properties and equipment and related accumulated depreciation accounts until they are removed from service. In the case of disposals, assets and related accumulated depreciation are removed from the accounts and the net amount, less any proceeds from disposal, is charged or credited to earnings. Obligations for costs associated with asset retirements, such as requirements to restore a site to its original condition, are accrued at net present value and amortized along with the related asset.
During the 2018 first quarter, Grace, with the assistance of an outside accounting firm, completed a study to evaluate the useful lives of its operating machinery and equipment, including a review of historical asset retirement data as well as review and analysis of relevant industry practices. As a result of this study, effective January 1, 2018, Grace revised the accounting useful lives of certain machinery and equipment, which was determined to be a change in accounting estimate and is being applied prospectively. As a result of this change in accounting estimate, Grace’s depreciation expense with respect to such machinery and equipment was reduced by $23.5 million, resulting in an increase to net income of $18.0 million or $0.27 per diluted share for the year ended December 31, 2018. Estimated useful lives for operating machinery and equipment previously ranged from 3 to 10 years.
Intangible assets with finite lives consist of technology, customer lists, trademarks and other intangibles and are amortized over their estimated useful lives, ranging from 1 to 30 years.
Grace reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. There were no impairment charges recorded in 2016, 2015 or 2014.any of the periods presented.
Goodwill    Goodwill arises from business combinations, and it is reviewed for impairment on an annual basis at October 31 and whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. Recoverability is assessed at the reporting unit level most directly associated with the business combination that generated the goodwill. For the purpose of measuring impairment, under the provisions of ASC 350 "Intangibles—Goodwill and Other," Grace has identified its operating segments as reporting units. Grace has evaluated its goodwill annually with no impairment charge required in any of the periods presented.
Financial Instruments    Grace uses commodity forward, swap and/or option contracts andcontracts; currency forward, swap, and/or option contracts; and interest rate swap contracts to manage exposure to fluctuations in commodity prices, and currency exchange rates, and interest rates. Grace does not hold or issue derivative financial instruments for trading purposes. Derivative instruments

are recorded at fair value in the Consolidated Balance Sheets as either assets or liabilities. For derivative instruments designated as fair value hedges, changes in the fair values of the derivative instruments closely offset changes in the fair values of the hedged items in "other“other (income) expense, net"net” in the Consolidated Statements of Operations. For derivative instruments designated as cash flow hedges, if the derivative instruments qualify for hedge accounting pursuant to ASC 815,gain or loss on the effective portion of any hedge is reported as "accumulatedin “accumulated other comprehensive income (loss)" in the Consolidated Balance Sheets until it is cleared to earnings during the same period in which the hedged item affects earnings. The ineffective portion of all hedges, and changes in the fair values of derivative instruments that are not designated as hedges are

recorded in current period earnings. Cash flows from derivative instruments are reported in the same category as the cash flows from the items being hedged.
Income Taxes    Deferred tax assets and liabilities are recognized with respect to the expected future tax consequences of events that have been recorded in the Consolidated Financial Statements. IfGrace reduces the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that all or a portion of deferred taxsuch assets will not be realized, arealized. The need to establish valuation allowance is provided against such deferred tax assets. The assessment of realization ofallowances for deferred tax assets is performed based onassessed quarterly.
In assessing the weightrequirement for, and amount of, a valuation allowance in accordance with the more likely than not standard, Grace gives appropriate consideration to all positive and negative evidence availablerelated to indicate whether the asset is recoverable, includingrealization of the deferred tax planning strategies that are prudentassets. This assessment considers, among other matters, the nature, frequency and feasible.severity of current and cumulative losses, forecasts of future profitability, domestic and foreign source income, the duration of statutory carryforward periods, and Grace’s experience with operating loss and tax credit carryforward expirations.
Tax benefits from an uncertain tax position are recognized only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities based on the technical merits of the position. Tax benefits recognized in the financial statementsConsolidated Financial Statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. Grace evaluates such likelihood based on relevant facts and tax law. Grace adjusts its recorded liability for income tax matters due to changes in circumstances or new uncertainties, such as amendments to existing tax law. Grace'sGrace’s ultimate tax liability depends upon many factors, including negotiations with taxing authorities in the jurisdictions in which it operates, outcomes of tax litigation, and resolution of disputes arising from federal, state, and foreign tax audits. Due to the varying tax laws in each jurisdiction management, with the assistance of local tax advisors as necessary, assesses individual matters in each jurisdiction on a case-by-case basis. Grace researches and evaluates its income tax positions, including why it believes they are compliant with income tax regulations, and these positions are documented as appropriate.
The TCJA (see “U.S. Tax Reform,” below) subjects a U.S. entity to tax on global intangible low-taxed income (“GILTI”) earned by certain foreign subsidiaries. An entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or to provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. Because Grace was evaluating the provision of GILTI as of December 31, 2017, it recorded no GILTI-related deferred amounts in 2017. After further consideration in the current year, Grace has elected to account for GILTI as a period expense in the year the tax is incurred. Grace has also adopted the tax law ordering approach for evaluating the impact of GILTI on the assessment of the realizability of US deferred tax assets.
Pension Benefits    Grace'sGrace’s method of accounting for actuarial gains and losses relating to its global defined benefit pension plans is referred to as "mark-to-market“mark-to-market accounting." Under mark-to-market accounting, Grace'sGrace’s pension costs consist of two elements: 1) ongoing costs recognized quarterly, which include service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; and 2) mark-to-market gains and losses recognized annually in the fourth quarter resulting from changes in actuarial assumptions, such as discount rates and the difference between actual and expected returns on plan assets. Should a significant event occur, Grace'sGrace’s pension obligation and plan assets are remeasured at an interim period, and the gains or losses on remeasurement are recognized in that period.
Stock-Based Compensation    The Company recognizes expenses related to stock-based compensation payment transactions in which it receives employee services in exchange for (a) equity instruments of the Company or (b) liabilities that are based on the fair value of the Company’s equity instruments or that may be settled by the issuance of equity instruments. Stock-based compensation cost for restricted stock units (RSUs)(“RSUs”) and share settled performance based units (PBUs)(“PBUs”) are measured based on the high/low average of the Company’s common stock on the date of grant. Cash settled performance based units (CSPBU) are remeasured at the end of each reporting period based on the closing fair market value of the Company’s common stock. Stock-based

compensation cost for stock options is estimated at the grant date based on each option’s fair value as calculated by the Black-Scholes option pricing model. The Company recognizes stock-based compensation cost as expense ratably on a straight-line basis over the requisite service period.
Currency Translation    Assets and liabilities of foreign subsidiaries (other than those located in countries with highly inflationary economies) are translated into U.S. dollars at current exchange rates, while revenues, costs and expenses are translated at average exchange rates during each reporting period. The resulting

translation adjustments are included in "accumulated“accumulated other comprehensive income (loss)" in the Consolidated Balance Sheets. The financial statements of any subsidiaries located in countries with highly inflationary economies are remeasured as if the functional currency were the U.S. dollar; the remeasurement creates translation adjustments that are reflected in net income in the Consolidated Statements of Operations.
Reclassifications    Certain amounts in prior years'years’ Consolidated Financial Statements have been reclassified to conform to the current year presentation. Such reclassifications have not materially affected previously reported amounts in the Consolidated Financial Statements.
Recently Issued Accounting Standards    In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers." This update is intended to remove inconsistencies and weaknesses in revenue requirements; provide a more robust framework for addressing revenue issues; improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; provide more useful information to users of financial statements through improved disclosure requirements; and simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. The new requirements are effective for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2016. The standard allows for two methods of adoption: (a) full retrospective adoption, meaning the standard is applied to all periods presented, or (b) modified retrospective adoption, meaning the cumulative effect of applying the new standard is recognized as an adjustment to the opening retained earnings balance. Grace will adopt the standard when it becomes effective. Grace has begun its preliminary assessment and is identifying specific areas of impact on its Consolidated Financial Statements. Grace has tentatively decided to adopt this standard under the modified retrospective approach and is still evaluating the impact to its financial statements and disclosures.
In July 2015, the FASB issued ASU 2015-11 "Simplifying the Measurement of Inventory." This update is part of the FASB's Simplification Initiative and is also intended to enhance convergence with the International Accounting Standards Board's ("IASB") measurement of inventory. The update requires that inventory be measured at the lower of cost or net realizable value for entities using FIFO (first-in, first-out) or average cost methods. The new requirements are effective for fiscal years beginning after December 15, 2016, and for interim periods within those fiscal years, with early adoption permitted. Grace will adopt this standard in 2017 and does not expect it to have a material effect on the Consolidated Financial Statements.
In February 2016, the FASB issued ASU 2016-02 "Leases“Leases (Topic 842)." This update is intended to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term, including optional payments where they are reasonably certain to occur. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. Currently, as a lessee, Grace is a party to a number of leases which, under existing guidance, are classified as operating leases and not recorded on the balance sheet but are expensed as incurred (See Note 3).incurred. Under the new standard, many of these leases will be recorded on the Consolidated Balance Sheets. Grace is currently evaluating the standard's effect on the financial statements and will adopt the standard in 2019.
In August 2016,July 2018, the FASB issued ASU 2016-15 "Classification2018-11 “Leases (Topic 842): Targeted Improvements,” which provides an additional transition method that allows entities to initially apply the new standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of Certain Cash Receiptsretained earnings in the period of adoption. Grace will adopt these standards in the 2019 first quarter under the modified retrospective approach permitted by ASU 2018-11. Grace is finalizing its implementation of the new standard and Cash Payments."expects to recognize material lease assets and lease liabilities on its Consolidated Balance Sheet upon adoption of Topic 842, but does not expect the standard to have a material impact on the Consolidated Statement of Operations.
In January 2018, the FASB issued ASU 2018-01 “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842.” This update is intendedprovides an optional transition practical expedient that allows an entity to reduce diversity in practice in how certain cash receipts and cash payments are presented and classifiedelect not to evaluate under Topic 842 existing or expired land easements not previously accounted for as leases. All land easements entered into or modified after the adoption of Topic 842 must be evaluated under Topic 842. Grace, which typically does not account for easements under current lease accounting, will use the transition practical expedient when adopting Topic 842 in the statement of cash flows. It addresses eight specific issues. The2019 first quarter.
In August 2018, the FASB issued ASU 2018-14 “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20).” This update adds, removes, and clarifies disclosure requirements related to defined benefit pension and other postretirement plans. Grace is required to adopt the amendments in this update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted.on January 1, 2021. Grace is currently evaluating the timing of adoption and does not expect itthe update to have a material effect on the Consolidated Financial Statements.
In November 2016,October 2018, the FASB issued ASU 2016-18 "Statement2018-16 “Derivatives and Hedging (Topic 815): Inclusion of Cash Flows (Topic 230): Restricted Cash", which requiresthe Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes.” This update permits use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815. Grace currently carries debt and derivatives that rely on the London Interbank Offered Rate (“LIBOR”) as a statementbenchmark rate. LIBOR is expected to be phased out as a benchmark rate by the end of cash flows explain2021. Grace expects its debt and financial instruments to continue to use LIBOR until the change duringrate is no longer available. To the period in the total of cash, cashextent LIBOR ceases to exist, Grace may need to renegotiate any

credit agreements and/or derivative contracts that utilize LIBOR as a factor in determining the interest rate. Currently, there is not a firm timeframe for this change. This update currently has no foreseeable impact on Grace’s Consolidated Financial Statements; however, it may have an effect in the future.
Recently Adopted Accounting Standards
Revenue Recognition
In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers (Topic 606)” (“ASC 606”). This update was intended to remove inconsistencies and weaknesses in revenue requirements; provide a more robust framework for addressing revenue issues; improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; provide more useful information to users of financial statements through improved disclosure requirements; and simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. Grace adopted ASC 606 with a date of initial application of January 1, 2018. Grace applied the standard to all customer contracts. As a result, Grace has changed its accounting policy for revenue recognition as detailed below.
Grace applied ASC 606 using the modified retrospective method, that is, by recognizing the cumulative effect of initially applying ASC 606 as an adjustment to “retained earnings” at the date of initial application. Results for periods beginning after December 31, 2017, are presented under ASC 606, while the comparative information has not been adjusted and continues to be reported in accordance with Grace’s historical accounting under ASC 605 “Revenue Recognition” (“ASC 605”).
Impact of Adoption
Except for the changes below, Grace has consistently applied its accounting policy for revenue recognition to all periods presented in the Consolidated Financial Statements.
Grace recorded a net increase to “retained earnings” of $2.5 million as of January 1, 2018, which represents the cumulative impact of adopting ASC 606, with a $3.2 million reduction to “other liabilities” and a $0.7 million reduction to “deferred income taxes.” The cumulative adjustment results from a change in accounting for contingent revenue related to technology licensing arrangements. Under ASC 605, certain revenue was not realized until a contractual contingency was resolved. Upon adoption of ASC 606, Grace estimates all forms of variable consideration, including contingent amounts, at the inception of the arrangement and recognizes it over the period of performance.
The tables below present the effect of the adoption of ASC 606 on Grace’s Consolidated Statements of Operations and Consolidated Balance Sheets.

ASU 2016-18 “Statement of Cash Flows (Topic 230): Restricted Cash”
In November 2016, the FASB issued ASU 2016-18 “Statement of Cash Flows (Topic 230): Restricted Cash,” which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new requirements are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption is permitted.

ASU 2017-07 “Compensation—Retirement Benefits (Topic 715)”
In March 2017, the FASB issued ASU 2017-07 “Compensation—Retirement Benefits (Topic 715).” This update requires that the service cost component of net benefit cost be presented with other compensation costs arising from services rendered. The remaining net benefit cost is either presented as a material effect online item in the statement of operations outside of a subtotal for income from operations, if presented, or disclosed separately. In addition, only the service cost component of net benefit cost can be capitalized. Grace adopted the update in the 2018 first quarter.
The changes in classification of net benefit costs within the Consolidated Statements of Operations have been retrospectively applied to all periods presented. The change in costs capitalizable into inventory was applied prospectively in accordance with the update. The tables below present the effect of the adoption of ASU 2017-07 on previously reported amounts.

Other Recently Adopted Accounting Standards
In January 2017, the FASB issued ASU 2017-01 “Business Combinations (Topic 805)," which provides a screen to determine when an integrated set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this Updateupdate (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output, and (2) remove the evaluation of whether a market participant could replace missing elements.

In January 2017, the FASB issued ASU 2017-04 “Intangibles—Goodwill and Other (Topic 350)." This Updateupdate modifies the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination.combination (“Step 2”). Because these amendments eliminate Step 2 from the goodwill impairment test, they should reduce the cost and complexity of evaluating goodwill for impairment.

Grace adopted this standardterm “modification,” which is currently defined as “a change in the 2016 first quarter.
In April 2015, the FASB issued ASU 2015-03 "Simplifying the Presentation of Debt Issuance Costs." This update is partany of the FASB's Simplification Initiative and is also intended to enhance convergence with the IASB's treatmentterms or conditions of debt issuance costs.a share-based payment award.” The update requires that debt issuance costs relatedentities to a recognized debt liability be presented inaccount for modifications of share-based payment awards unless the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. In August 2015, the FASB issued ASU 2015-15 "Presentation(1) fair value, (2) vesting conditions, and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements."

recognize,award before modification. Grace adopted the update in the same period's financial statements, the2018 first quarter, and it did not have an effect on earningsthe Consolidated Financial Statements.
In February 2018, the FASB issued ASU 2018-02 “Income Statement—Reporting Comprehensive Income (Topic 220).” This update addresses the revaluation of deferred tax assets and liabilities due to the Tax Cuts and Jobs Act of 2017 impacting income from continuing operations, even if the initial income tax effects were recognized in other comprehensive income. The update allows entities to reclassify the tax effects that were originally in other comprehensive income from accumulated other comprehensive income to retained earnings. The update requires entities to disclose whether the election was made and a description of the income tax effects. The update can be: (a) applied to the period of adoption, or (b) applied retrospectively to each period in which the Tax Cuts and Jobs Act of 2017 is in effect. Grace adopted the update in the 2018 fourth quarter and reclassified $2.2 million from “accumulated other comprehensive income (loss)” to “retained earnings” as of December 31, 2018.
U.S. Tax Reform    On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “TCJA”) was signed into law, making significant changes to the Internal Revenue Code. Changes include a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of foreign earnings. On December 22, 2017, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in depreciation, amortization,situations when a registrant does not have the necessary information available, prepared, or otheranalyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects resultingof the TCJA.
In 2017 and the first nine months of 2018, Grace recorded provisional amounts for certain enactment-date effects of the TCJA by applying the guidance in SAB 118 because it had not yet completed its enactment-date accounting for these effects. During the fourth quarter of 2018, Grace completed its accounting for all of the enactment-date income tax effects of the TCJA. As further discussed below, during 2018, Grace recognized a benefit of $17.1 million from the changeadjustments to the provisional amounts calculatedrecorded at December 31, 2017, and included these adjustments as ifa component of income tax expense from continuing operations.
The provisional amount related to the accounting had been completedremeasurement of certain deferred tax assets and liabilities, based on the rates at the acquisition date. Grace adopted this standardwhich they are expected to reverse in the 2016 third quarter. future, was a charge of $120.1 million at December 31, 2017. Upon further analysis of certain aspects of the TCJA and refinement of its calculations during the year ended December 31, 2018, Grace reduced the provisional amount by $4.9 million.
The provisional amounts related to the one-time transition tax on the mandatory deemed repatriation of foreign earnings and the state and foreign taxes on the unremitted earnings were $37.4 million and $4.9 million, respectively, at December 31, 2017. Upon further analyses of the TCJA and notices and regulations issued and proposed by the U.S. Department of the Treasury and the Internal Revenue Service, Grace finalized its calculation of the transition tax liability during 2018. Grace decreased the December 31, 2017, provisional amount by $9.5 million for the deemed repatriation of foreign earnings and by $2.7 million for the state and foreign taxes on unremitted earnings. These amounts are included as a component of income tax expense from continuing operations.
Additionally, in 2017, Grace provisionally released valuation allowances on a portion of its state net operating losses and federal tax credits of $2.0 million and $17.4 million. Grace made no adjustments to these provisional amounts in 2018.
See Note 20.
Accounting7 for Stock Compensation
In March 2016, the FASB issued ASU 2016-09 "Compensation—Stock Compensation," which is part of the FASB's Simplification Initiative. The update requires that excess tax benefits and deficiencies be recorded in the income statement when the awards vest or are settled. It also eliminates the requirement that excess tax benefits be realized (reduce cash taxes payable) before being recognized. Previously, an entity could not recognize excess tax benefits if the tax deduction increased a net operating loss ("NOL") or tax credit carryforward. The updated standard no longer requires cash flowsmore information related to excess tax benefits to be presented as a financing activity separate from other income tax cash flows. The update also allows Grace to repurchase more of an employee's shares for tax withholding purposes without triggering liability accounting, clarifies that all cash payments to taxing authorities made on an employee's behalf for withheld shares should be presented as a financing activity on the statement of cash flows, and provides for an accounting policy election to account for forfeitures as they occur.
Grace elected to early adopt this update in the 2016 second quarter, which requires any adjustments to be reflected as of January 1, 2016. This resulted in the recognition of excess tax benefits on the Consolidated Balance Sheet that were previously not recognized, as the benefits would have increased Grace's NOL or tax credit carryforwards. The recognition increased Grace's net deferred tax asset by $70.4 million ($90.9 million net of a $20.5 million valuation allowance) as of January 1, 2016.
In addition, Grace will recognize excess tax benefits in the provision for income taxes rather than paid-in capital for 2016 and future periods. Grace has elected to continue to estimate forfeitures expected to occur to determine the amount of compensation expense to be recognized each period.

Grace used $600 million of those funds to repay $526.9 million of its U.S. dollar term loan, including the $250 million borrowed under a delayed draw facility, and €67.3 million of its euro term loan. As a result, Grace recorded a loss on early extinguishment of $11.1 million, which is included in "other (income) expense" in the Consolidated Statements of Operations.million. See Note 21 for information related to the Separation.
Senior Notes
On September 16, 2014, Grace-Conn.Grace–Conn. (the "Issuer"“Issuer”) issued $1,000.0 million of senior unsecured notes (the "Notes"“Notes”) in two tranches:
(a)$700 million in aggregate principal amount of Notes due 2021 at a coupon rate of 5.125%, and
(b)$300 million in aggregate principal amount of Notes due 2024 at a coupon rate of 5.625%.
The Notes were priced at 100% of par and were offered and sold pursuant to exemptions from registration under the Securities Act of 1933, as amended, (the "Securities Act"“Securities Act”). The net proceeds received from issuance were $985.5 million, a portion of which was used to terminate Grace'sGrace’s obligations under the deferred payment agreement with the PI Trust (as defined in Note 10) for $632.0 million and to repay amounts outstanding under Grace'sGrace’s revolving credit facility. The remaining proceeds from the Notes were used to partially fund the settlement of the warrant issued to the PI Trust (as defined in Note 10) and for other general corporate purposes. Interest is payable on the Notes on each April 1 and October 1.
Grace may redeem some or all of the Notes at any time at a price equal to the greater of (i) 100% of the principal amount of the Notes redeemed plus accrued and unpaid interest and (ii) the sum, as determined by an independent investment banker, of the present values of the remaining scheduled payments of principal and interest (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the treasury rate plus 50 basis points, in each case, plus accrued and unpaid interest. In the event of a change in control, Grace will be required to offer to purchase the Notes at a price equal to 101% of the aggregate principal amount outstanding plus accrued and unpaid interest.
The Notes are jointly and severally guaranteed on a full and unconditional senior unsecured basis by the Company and Alltech Associates, Inc., a wholly-owned subsidiary of the Issuer (the "Guarantors"“Guarantors”). The Notes and guarantees are senior obligations of the Issuer and the Guarantors, respectively, and will rank equally with all of the existing and future unsubordinated obligations of the Issuer and the Guarantors, respectively. The Notes are

effectively subordinated to any secured indebtedness to the extent of the value of the assets securing such indebtedness, and structurally subordinated to the debt and other liabilities of Grace’s non-guarantor subsidiaries.
The Notes were issued subject to covenants that limit the Issuer’s and certain of its subsidiaries’ ability, subject to certain exceptions and qualifications, to (i) create or incur liens on assets, (ii) enter into any sale and leaseback transaction and (iii) in the case of the Issuer, merge or consolidate with another company. Grace is in compliance with these covenants.
The Notes were also issued subject to customary events of default which include (subject in certain cases to customary grace and cure periods), among others, nonpayment of principal or interest; breach of other agreements in the Indenture; failure to pay certain other indebtedness; failure to discharge a final judgment for the payment of $75 million or more (excluding any amounts covered by insurance or indemnities) rendered against the Issuer or any of its significant subsidiaries; and certain events of bankruptcy or insolvency. Generally, if any event of default occurs, the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding series of Notes may declare all the Notes of such series to be due and payable immediately.
The Separation had no impact on the payment terms or other terms of the Notes, and they remain obligations of Grace.

Grace has filed the full text of such agreements copies of which have been filed with the SEC.SEC, which are readily available on the Internet at www.sec.gov.
6. Fair Value Measurements and Risk
Certain of Grace'sGrace’s assets and liabilities are reported at fair value on a gross basis. ASC 820 "Fair“Fair Value Measurements and Disclosures"Disclosures” defines fair value as the value that would be received at the measurement date in the principal or "most advantageous"“most advantageous” market. Grace uses principal market data, whenever available, to value assets and liabilities that are required to be reported at fair value.
Grace has identified the following financial assets and liabilities that are subject to the fair value analysis required by ASC 820:
Fair Value of Debt and Other Financial Instruments    Debt payable is recorded at carrying value. Fair value is determined based on Level 2 inputs, including expected future cash flows (discounted at market interest rates), estimated current market prices, and quotes from financial institutions.
At December 31, 2016,2018, the carrying amounts and fair values of Grace'sGrace’s debt were as follows:

6. Fair Value Measurements and Risk (Continued)

At December 31, 2016,2018, the recorded values of other financial instruments such as cash equivalents and trade receivables and payables approximated their fair values, based on the short-term maturities and floating rate characteristics of these instruments.
Commodity DerivativesFrom time to time, Grace enters into commodity derivatives such as fixed-rate swaps or options with financial institutions to mitigate the risk of volatility of prices of natural gas or other commodities. Under fixed-rate swaps, Grace locks in a fixed rate with a financial institution for future purchases, purchases its commodity from a supplier at the prevailing market rate, and then settles with the bank for any difference in the rates, thereby swapping a variable rate for a fixed rate.
The valuation of Grace's fixed-rate natural gas swaps was determined using a market approach, based on natural gas futures trading prices quoted on the New York Mercantile Exchange. Commodity fixed-rate swaps with maturities of not more than 15 months are used and designated as cash flow hedges of forecasted purchases of natural gas. The effective portion of the gain or loss on the commodity contracts is recorded in "accumulated other comprehensive income (loss)" and reclassified into income in the same period or periods that the underlying commodity purchase affects income. At December 31, 2016, there were no open fixed-rate natural gas swaps.

The valuation of Grace's fixed-rate aluminum swaps was determined using a market approach, based on aluminum futures trading prices quoted on the London Metal Exchange. Commodity fixed-rate swaps with maturities of not more than 15 months are used and designated as cash flow hedges of forecasted purchases of aluminum. Current open contracts hedge forecasted transactions until November 2017. The effective portion of the gain or loss on the commodity contracts is recorded in "accumulated other comprehensive income (loss)" and reclassified into income in the same period or periods that the underlying commodity purchase affects income. At December 31, 2016, the contract volume, or notional amount, of the commodity contracts was 1.3 million pounds with a total contract value of $1.0 million.
Currency Derivatives    Because Grace operates and/or sells to customers in over 6070 countries and in over 30 currencies, its results are exposed to fluctuations in currency exchange rates. Grace seeks to minimize exposure to these fluctuations by matching sales in volatile currencies with expenditures in the same currencies, but it is not always possible to do so. From time to time, Grace will useuses financial instruments such as currency forward contracts, options, swaps, or combinations thereof to reduce the risk of certain specific transactions. However, Grace does not have a policy of hedging all exposures, because management does not believe that such a level of hedging would be cost-effective. Forward contracts with maturities of not more than 36 months are used and designated as cash flow hedges of forecasted repayments of intercompany loans. The effective portion of gains and losses on these currency hedges is recorded in “accumulated other comprehensive income (loss)” and reclassified into “other (income) expense, net” to offset the remeasurement of the underlying hedged loans. Excluded components (forward points) on these hedges are amortized to income on a systematic basis.
Grace also enters into foreign currency forward contracts and swaps to hedge a portion of its net outstanding monetary assets and liabilities. These forward contracts and swaps are not designated as hedging instruments under applicable accounting guidance, and therefore all changes in the fair value of the forward contracts and swaps are recorded in “other (income) expense, net,” in the Consolidated Statements of Operations. These forward contracts and swaps are intended to offset the foreign currency gains or losses associated with the underlying monetary assets and liabilities.
The valuation of Grace'sGrace’s currency exchange rate forward contracts and swaps is determined using both a market approach and an income approach. Inputs used to value currency exchange rate forward contracts and swaps consist of: (1) spot rates, which are quoted by various financial institutions; (2) forward points, which are primarily affected by changes in interest rates; and (3) discount rates used to present value future cash flows, which are based on the London Interbank Offered Rate (LIBOR) curve or overnight indexed swap rates. Total notional amounts for forward contracts and swaps outstanding at December 31, 2018, were $171.6 million.
Cross-Currency Swap Agreements    Grace uses cross-currency swaps designated as cash flow hedges to manage fluctuations in currency exchange rates and interest rates on variable rate debt. The effective portion of gains and losses on these cash flow hedges is recorded in “accumulated other comprehensive income (loss)” and reclassified into “other (income) expense, net” and “interest expense and related financing costs” during the hedged period.
In April 2018, in connection with the Credit Agreement (see Note 5), Grace entered into new cross-currency swaps beginning on April 3, 2018, and maturing on March 31, 2023, to synthetically convert $600.0 million of U.S. dollar-denominated floating rate debt into €490.1 million of euro-denominated debt fixed at 2.0231%. These cross-currency swaps were de-designated and terminated on November 5, 2018, and replaced with new, at-market cross-currency swaps beginning on November 5, 2018, and maturing on March 31, 2023, to synthetically convert $600.0 million of U.S. dollar-denominated floating rate debt into €525.9 million of euro-denominated debt fixed at 1.785%. Grace received $33.1 million in cash proceeds from the swap settlement. The valuation of these cross-currency swaps is determined using an income approach, using LIBOR and EURIBOR (Euro Interbank Offered Rate) swap curves, currency basis spreads, and euro/U.S. dollar exchange rates.
Debt and Interest Rate Swap Agreements    Grace uses interest rate swaps designated as cash flow hedges to manage fluctuations in interest rates on variable rate debt. The effective portion of gains and losses on these interest rate cash flow hedges is recorded in "accumulated“accumulated other comprehensive income (loss)" and reclassified into "interest“interest expense and related financing costs"costs” during the hedged interest period.
In connection with its emergence financing, Grace entered into an interest rate swapswaps beginning on February 3, 2015, and maturing on February 3, 2020, fixing the LIBOR component of the interest on $250$250.0 million of Grace'sGrace’s term debt at a rate of 2.393%.

In connection with the Credit Agreement (see Note 5), Grace entered into new interest rate swaps beginning on April 3, 2018, and maturing on March 31, 2023, fixing the LIBOR component of the interest on $100.0 million of term debt at 2.775%. The valuation of these interest rate swaps is determined using an income approach, using prevailing market interest rates and discount rates to present value future cash flows based on the forward LIBOR yield curves.

Grace's deferred tax assets decreased by $6.5 million from December 31, 2015, to December 31, 2016. As discussed in Notes 1 and 21, the Separation was completed on February 3, 2016. In conjunction with the Separation, $58.9 million of Grace's deferred tax assets were transferred to GCP in 2016. This decrease was offset by the adoption of ASU 2016-09, which resulted in the recognition of excess tax benefits in the Consolidated Balance Sheets which had not previously been recognized. This increased Grace's deferred tax assets as of January 1, 2016, by $70.4 million, which is net of a $20.5 million valuation allowance.
Grace has recorded a valuation allowance to reduce its net deferred tax assets to the amount that is more likely than not to be realized. Grace considers forecasted earnings, recent past and future taxable income, the mix of earnings in the jurisdictions in which it operates and, where applicable, prudent and feasible tax planning strategies in determining the need for these valuation allowances. The valuation allowance increased by $23.0 million from December 31, 2015, to December 31, 2016, due to $20.5 million for deferred tax assets recognized upon adoption of ASU 2016-09 and $2.5 million for a change in the ability to utilize NOL carryforwards as a result of the Separation.

The realization of deferred tax assets is dependentdifference between the benefit from (provision for) income taxes on continuing operations at the generation of sufficient taxable income in the appropriate tax jurisdictions. Grace believes it is more likely than not that the remaining deferred tax assets will be realized. If Grace were to determine that it would not be able to realize a portion of its net deferred tax assets in the future, for which there is currently no valuation allowance, an adjustment to the net deferred tax assets would be charged to earnings in the period such determination was made. Conversely, if Grace were to make a determination that it is more likely than not that deferred tax assets, for which there is currently a valuation allowance, would be realized, the related valuation allowance would be reduced and a benefit to earnings would be recorded.
U.S. Federal and State Net Operating Losses and Credit Carryforwards
Grace generated approximately $1,800 million in U.S. federal tax deductions relating to its emergence from bankruptcy. The deductions generated a U.S. federal and state net operating loss in 2014, which Grace has carried forward and expects to utilize in subsequent years. Under U.S. federal income tax law, a corporation is generally permitted to carry forward NOLsrate of 21% for a 20-year period2018 (35% for deduction against future taxable income. Grace also generated U.S. federal tax deductions of $30 million upon payment of the ZAI PD deferred payment obligation on February 3, 2017. (See Note 10). As of December 31, 2016, Grace had U.S. federal NOLs of approximately $857 million expiring between 2034 and 2035 and state NOLs of approximately $733 million on a post apportioned basis expiring between 2017 and 2035.2016) and Grace’s overall income tax provision is summarized as follows:

In 2017 Grace will need to generate approximately $1,800 million of U.S. federal taxableestimated its provision for income by 2035 (or approximately $95 million per year duringtaxes in accordance with the carryforward period) to fully realizeTCJA and guidance available at the U.S. federaltime and as a majority of the U.S. state net deferred tax assets. Grace believes that it will generate taxable income during this period sufficient to use all available NOL carryforwards and future tax deductions prior to expiration. Grace hasresult recorded a valuation allowance of $17.3 million (before federal benefit) on the state NOLs that it believes will not be utilized prior to expiration.
Included in Grace’s U.S. federal tax credit carryforwards ($183.2 million as of December 31, 2016) are $144.4 million of foreign tax credits, which expire between 2018 and 2026. Grace has recorded a valuation allowance of $17.7 million on the credit carryforwards that it believes will not be utilized prior to expiration.
Unrepatriated Foreign Earnings
Grace has not provided for U.S. federal, state and foreign deferred income taxes on $536.6 million of undistributed earnings of foreign subsidiaries. Grace expects that these earnings will be permanently reinvested by such subsidiaries except in certain instances where repatriation attributable to current earnings results in minimal or no U.S. tax consequences. The unrecorded deferred tax liability associated with these earnings is $27.4 million. Grace repatriated earnings of $5.1 million, $173.1 million, and $38.9 million from its non-U.S. subsidiaries in 2016, 2015, and 2014, respectively, incurring an insignificant amount of U.S.provisional income tax expense or benefitof $143.0 million in 2014. the 2017 fourth quarter.
The provisional amount related to the remeasurement of certain deferred tax effect ofassets and liabilities, based on the rates at which they are expected to reverse in the future, was $120.1 million.
The provisional amounts related to the one-time transition tax on the mandatory deemed repatriation of foreign earnings in 2015 and 2016 is discussed in detail below.
As ofthe state and foreign taxes on the unremitted earnings were $37.4 million and $4.9 million, respectively. Effective December 31, 2014,2017, Grace had the intent and abilityis no longer indefinitely reinvested with respect to indefinitely reinvest undistributedits historical unremitted earnings of its foreign subsidiaries outsidesubsidiaries. In the U.S. However,fourth quarter of 2018 Grace finalized the provisional amounts recorded in connection with the Separation, during 2015 Grace repatriated a totalfourth quarter of $173.12017, which resulted in reductions of $9.5 million and $2.7 million in the one-time transition tax of foreign earnings fromand the state and foreign taxes on the unremitted earnings, respectively. The net reduction of the transition tax was due primarily to additional review of historical tax attributes of Grace’s foreign subsidiaries transferred to GCP pursuant to the Separation. Such amount was determinedand changes in estimate based on an analysisguidance issued during the year. The adjustment of each non-U.S. subsidiary's requirements for working capital, debt repayment and strategic initiatives. Grace also considered local country legal and regulatory restrictions. Grace includedGrace’s provisional transition tax expense was recorded as a change in discontinued operationsestimate in accordance with SAB 118. Despite the completion of $19.0 million in 2015Grace’s accounting for repatriation and $1.3 million in 2016 for deemed repatriation attributable to both current and prior years' earnings. The tax effectthe TCJA under SAB 118, many aspects of the repatriation is determined by several variables includinglaw remain uncertain at this time. We expect updates to federal and state guidance and regulations will continue throughout 2019. Grace will monitor and assess the tax rate applicable to the entity making the distribution, the cumulative earnings and associated foreign taxesimpact of the entity and the extent to which those earnings may have already been taxed in the U.S.
Grace believes that the Separation was a one-time, non-recurring event and that recognition of deferred taxes on undistributed earnings would not have occurred if not for the Separation. Subsequent to the Separation, Grace expects undistributed prior-year earnings of its foreign subsidiaries to remain permanently reinvestedany new guidance as it becomes available.

Grace’s net deferred tax assets decreased by $29.8 million from December 31, 2016.2017, to December 31, 2018, largely as a result of the utilization of net operating losses, the reduction of pension related deferred tax assets, and a reduction in prepaid royalty deferred tax assets. These reductions were partially offset by an increase in Grace’s federal tax credit carryforwards and unrealized foreign currency gains and losses.
Grace reduces the carrying amounts of deferred tax assets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized (see Note 1). The valuation allowance increased by $7.6 million from December 31, 2017, to December 31, 2018, due to increases of $4.9 million related to expected foreign tax credit utilization, $3.9 million related to a foreign deferred tax asset the company is unlikely to utilize, and $1.4 million related to foreign net operating loss carryforwards, offset by a $2.6 million reduction to the valuation allowance for state deferred taxes.
U.S. Federal and State Net Operating Losses and Credit Carryforwards    Grace has $299.4 million in federal tax credit carryforwards before unrecognized tax benefits. In order to fully utilize the credits before they expire from 2021 to 2028 Grace will need to generate income of approximately $1.4 billion.
Grace has U.S. federal and state net operating losses. The deferred tax asset related to federal NOLs is $48.8 million before unrecognized tax benefits. In order to fully utilize the NOLs before they expire in 2035, Grace will need to generate approximately $232 million in U.S. taxable income. The deferred tax asset, net of federal benefit, before valuation allowance related to state NOLs is $54.5 million before unrecognized tax benefits. In order to fully utilize the state NOLs before they expire (from 2018 to 2035), Grace would need to generate approximately $1.9 billion in state taxable income.
Unrecognized Tax Benefits    The balance of unrecognized tax benefits at December 31, 2018, was $14.1 million compared with $17.7 million at December 31, 2017. A rollforward of the unrecognized tax benefits for the three years ended December 31, 2018, follows.

Grace notes that there are attributes generated in prior years that are otherwise closed by statute and were carried forward into years that are open to examination. Those attributes may still be subject to adjustment to the extent utilized in open years.
As a multinational taxpayer, Grace is under continual audit by various tax authorities. Grace believes that the amount of the liability for unrecognized tax benefits will be unchanged in the next 12 months.

Fully-funded plans include several advance-funded plans where the fair value of the plan assets exceeds the projected benefit obligation ("PBO"). Underfunded plans include a group of advance-funded plans that are underfunded on a projected benefit obligation ("PBO"(“PBO”) basis. Unfunded plans include several plans that are funded on a pay-as-you-go basis, and therefore, the entire PBO is unfunded. The combined balance of the underfunded and unfunded plans was $438.7 million as of December 31, 2016.
Grace maintains defined benefit pension plans covering current and former employees of certain business units and divested business units who meet age and service requirements. Benefits are generally based on final average salary and years of service. Grace funds its U.S. qualified pension plans ("(“U.S. qualified pension plans"plans”) in accordance with U.S. federal laws and regulations. Non-U.S. pension plans ("(“non-U.S. pension plans"plans”) are funded under a variety of methods, as required under local laws and customs. The U.S. salaried plan was closed to new entrants after January 1, 2017. U.S. salaried employees and certain U.S. hourly employees that are hired on or after January 1, 2017, and employees in Germany that are hired on or after January 1, 2016, will participate in enhanced defined contribution plans instead of defined benefit pension plans.

8. Pension Plans and Other Postretirement BenefitRetirement Plans (Continued)

Grace also provides, through nonqualified plans, supplemental pension benefits in excess of U.S. qualified pension plan limits imposed by federal tax law. These plans cover officers and higher-level employees and serve to increase the combined pension amount to the level that they otherwise would have received under the U.S. qualified pension plans in the absence of such limits. The nonqualified plans are unfunded and Grace pays the costs of benefits as they are due to the participants.
During 2018, Grace implemented a special lump sum and early commencement window for certain terminated vested participants who terminated employment prior to May 1, 2018, and had not previously commenced their pension benefits. As a result of the transaction, the U.S. qualified pension plans paid $42.2 million in lump sum distributions that reduced the PBO by $43.5 million and resulted in a $1.3 million gain.
Additionally, in the 2018 fourth quarter, Grace entered into an agreement with Prudential Financial, Inc. (“Prudential Financial”) to purchase a group annuity contract for $116.4 million that transferred $117.4 million of our U.S. pension plan obligations to Prudential Financial. Prudential Financial assumed responsibility to pay monthly annuities to certain retirees and beneficiaries that were receiving a monthly benefit from certain U.S. pension plans. Grace recognized a $1.0 million gain on the settlement.
At the December 31, 2016,2018, measurement date for Grace'sGrace’s defined benefit pension plans, the PBO was $1,543.3$1,332.7 million as measured under U.S. GAAP compared with $1,477.6$1,648.7 million as of December 31, 2015.2017. The PBO basis reflects the present value (using a 4.06%4.22% weighted average discount rate for U.S. plans and a 1.91%2.17% weighted average discount rate for non-U.S. plans as of December 31, 2016)2018) of vested and non-vested benefits earned from employee service to date, based upon current services and estimated future pay increases for active employees.
On an annual basis a full remeasurement of pension assets and pension liabilities is performed based on Grace'sGrace’s estimates and actuarial valuations. These valuations reflect the terms of the plan and use participant-specific information as well as certain key assumptions provided by management.
Postretirement Benefits Other Than Pensions    Grace has provided postretirement health care and life insurance benefits for retired employees of certain U.S. business units and certain divested business units. These plans are unfunded and Grace pays a portion of the costs of benefits under these plans as they are incurred. Grace applies ASC 715 "Compensation—Retirement Benefits" to these plans, which requires that the future costs of postretirement health care and life insurance benefits be accrued over the employees' years of service. Actuarial gains and losses are recognized in the Consolidated Balance Sheets as a component of Shareholders' Equity, with amortization of the net actuarial gains and losses that exceed 10 percent of the accumulated postretirement benefit obligation recognized each quarter in the Consolidated Statements of Operations over the average future service period of active employees.
In June 2014, Grace announced that it would discontinue its postretirement medical plan for all U.S. employees effective October 31, 2014, and eliminate certain postretirement life insurance benefits. As a result of these actions, Grace recognized a gain of $41.9 million in other comprehensive income in the 2014 second quarter. Grace amortized $39.5 million from accumulated other comprehensive income into the Consolidated Statement of Operations during the five-month period from June to October 2014.
The postretirement plan was further remeasured as of September 30, 2015, and December 31, 2016, due to plan amendments to eliminate certain other postretirement life insurance benefits, which resulted in curtailment gains of $4.5 million and $0.5 million, respectively.
Defined Contribution Retirement Plan    Grace sponsors a defined contribution retirement plan for its employees in the United States. This plan is qualified under section 401(k) of the U.S. tax code. Currently, Grace contributes an amount equal to 100% of employee contributions, up to 6% of an individual employee'semployee’s salary or wages. Grace'sGrace’s cost related to this benefit plan was $11.112.6 million, $10.411.5 million, and $9.311.1 million for the years ended December 31, 20162018, 20152017, and 20142016, respectively.

(1)Non-U.S. estimated benefit payments for 20172019 and future periods have been translated at the applicable December 31, 2016,2018, exchange rates.
Discount Rate Assumption    The assumed discount rate for pension plans reflects the market rates for high-quality corporate bonds currently available and is subject to change based on changes in overall market interest rates. For the U.S. qualified pension plans, the assumed weighted average discount rate of 4.06%4.22% as of December 31, 20162018, was selected by Grace, in consultation with its independent actuaries, based on a yield curve constructed from a portfolio of high quality bonds for which the timing and amount of cash outflows approximate the estimated payouts of the plan.
As of December 31, 20162018 and 20152017, the German pension plans represented approximately 92% and 90%91%, respectively, of the benefit obligation of the non-U.S. pension plans. The assumed weighted average discount rate as of December 31, 20162018, for Germany (1.78%2.05%) was selected by Grace, in consultation with its independent actuaries, based on a yield curve constructed from a portfolio of euro-denominated high quality bonds for which

the timing and amount of cash outflows approximate the estimated payouts of the plans. The assumed discount rates for the remaining non-U.S. pension plans were determined based on the nature of the liabilities, local economic environments and available bond indices.
As

8. Pension Plans and interest cost components of defined benefit pension expense. Previously, Grace estimated service and interest costs using a single weighted average discount rate derived from the same yield curve used to measure the projected benefit obligation. For 2016, Grace elected to measure service and interest costs by applying the specific spot rates along that yield curve to the plans’ liability cash flows. Grace believes the new approach provides a more precise measurement of service and interest costs by aligning the timing of the plans’ liability cash flows to the corresponding spot rates on the yield curve. This change did not affect the measurement of the projected benefit obligation as of December 31, 2015. Grace considers this a change in accounting estimate, which is being accounted for prospectively as of January 1, 2016.Other Retirement Plans (Continued)

Investment Guidelines for Advance-Funded Pension Plans    The investment goal for the U.S. qualified pension plans subject to advance funding is to earn a long-term rate of return consistent with the related cash flow profile of the underlying benefit obligation. The plans are pursuing a well-defined risk management strategy designed to reduce investment risks as their funded status improves.
The U.S. qualified pension plans have adopted a diversified set of portfolio management strategies to optimize the risk reward profile of the plans:
Liability hedging portfolio: primarily invested in intermediate-term and long-term investment grade corporate bonds in actively managed strategies.
GrowthReturn-seeking portfolio: invested in a diversified set of assets designed to deliver performance in excess of the underlying liabilities with controls regarding the level of risk.
U.S. equity securities: the portfolio contains domestic equities that are passively managed to the S&P 500 and Russell 2000 benchmarkbenchmarks and an allocation to an active portfolio benchmarked to the Russell 2000.Mid-Cap and Russell 2000 indices.
Non-U.S. equity securities: the portfolio contains non-U.S. equities in an actively managed strategy.strategy benchmarked to the MSCI ACWI ex US index. Currency futures and forward contracts may be held for the sole purpose of hedging existing currency risk in the portfolio.
Other investments: may include (a) high yield bonds: fixed income portfolio of securities below investment grade including up to 30% of the portfolio in non-U.S. issuers; and (b) global real estate securities: portfolio of diversified REIT and other liquid real estate related securities. These portfolios combine income generation and capital appreciation opportunities from developed markets globally.
Liquidity portfolio: invested in short-term assets intended to pay periodic plan benefits and expenses.
For 20162018, the expected long-term rate of return on assets for the U.S. qualified pension plans was 5.50%5.25%. Average annual returns over one-, three-, five-, and ten-year periods were approximately 9%(3)%, 6%, 5%, 7%, and 5%8%, respectively.
The expected return on plan assets for the U.S. qualified pension plans for 20162018 was selected by Grace, in consultation with its independent actuaries, using an expected return model. The model determines the weighted average return for an investment portfolio based on the target asset allocation and expected future returns for each asset class, which were developed using a building block approach based on observable inflation, available interest rate information, current market characteristics, and historical results.
The target allocation of investment assets at December 31, 2018, and the actual allocation at December 31, 2018 and 2017, for Grace’s U.S. qualified pension plans are as follows:

8. Pension Plans and Other Postretirement Benefit Plans (Continued)

Non-U.S. pension plans accounted for approximately 2% of total global pension assets at December 31, 20162018 and 2015.2017. Each of these plans, where applicable, follows local requirements and regulations. Some of the local requirements include the establishment of a local pension committee, a formal statement of investment policy and procedures, and routine valuations by plan actuaries.
The target allocation of investment assets for non-U.S. pension plans varies depending on the investment goals of the individual plans. The plan assets of the Canadian pension plan represent approximately 97%96% and 92%97% of the total non-U.S. pension plan assets at December 31, 20162018 and 20152017, respectively. The expected long-term rate of return on assets for the Canadian pension plan was 5.25%4.75% for 20162018.
The target allocation of investment assets at December 31, 20162018, and the actual allocation at December 31, 20162018 and 20152017, for the Canadian pension plan are as follows:

Although the outcome of each of the matters discussed below cannot be predicted with certainty, Grace has assessed its risk and has made accounting estimates as required under U.S. GAAP.
Legacy Product and Environmental Liabilities
Legacy Product Liabilities    Grace emerged from an asbestos-related Chapter 11 bankruptcy on February 3, 2014 (the "Effective Date"“Effective Date”). Under its plan of reorganization, all pending and future asbestos-related

claims are channeled for resolution to either a personal injury trust (the "PI Trust"“PI Trust”) or a property damage trust (the "PD Trust"“PD Trust”). The trusts are the sole recourse for holders of asbestos-related claims. The channeling injunctions issued by the bankruptcy court prohibit holders of asbestos-related claims from asserting such claims directly against Grace.
Grace has satisfied all of its financial obligations to the PI Trust. Grace has fixed and contingent financial obligations remaining to the PD Trust. With respect to property damage claims related to Grace’s former Zonolite attic insulation product installed in the U.S. ("(“ZAI PD Claims"Claims”), the PD Trust was funded with $34.4 million on the Effective Date and with $30.0 million on February 3, 2017. The $30.0 million liability was included in "debt payable within one year" in the accompanying Consolidated Balance Sheets as of December 31, 2016. Grace is also obligated to make up to 10 contingent deferred payments of $8 million each per year to the PD Trust in respect of ZAI PD Claims during the 20-year period beginning on the fifth anniversary of the Effective Date, with each such payment due only if the assets of the PD Trust in respect of ZAI PD Claims fall below $10 million during the preceding year. As of December 31, 2018, Grace has evaluated the activity in the PD Trust with respect to ZAI PD Claims and other trust expenses. Through December 31, 2018, the PD Trust has paid approximately $15 million in ZAI PD Claims, approximately $6 million in operating and education expenses, and approximately $15 million in one-time attorneys’ fees. The PD Trust balance was approximately $30 million as of December 31, 2018. Grace expects ZAI PD Claims payments to decline over time but has limited information to estimate the amount and timing of future claims payments. It is reasonably possible that one or more contingent deferred payments will be made in the future. Grace estimates the present value of reasonably possible future payments to range between $0 million and $20 million. Grace has not accrued for the 10 additionalany contingent deferred payments as Graceit does not currently believe they arethat payment is probable.

timing of future claims payments and any contingent deferred payments at that time. Grace is not obligated to make additional payments to the PD Trust in respect of ZAI PD Claims beyond the payments described above. Grace has satisfied all of its financial obligations with respect to Canadian ZAI PD Claims.
With respect to other asbestos property damage claims ("(“Other PD Claims"Claims”), claims unresolved as of the Effective Date are to be litigated in the bankruptcy court and any future claims are to be litigated in a federal district court, in each case pursuant to procedures approved by the bankruptcy court. To the extent any such Other PD Claims are determined to be allowed claims, they are to be paid in cash by the PD Trust. Grace is obligated to make a payment to the PD Trust every six months in the amount of any Other PD Claims allowed during the preceding six months plus interest (if applicable) and the amount of PD Trust expenses for the preceding six months (the "PD Obligation"“PD Obligation”). Grace has not paid any Other PD Claims since emergence. Annual expenses have been approximately $0.2 million per year. The aggregate amount to be paid under the PD Obligation is not capped, and Grace may be obligated to make additional payments to the PD Trust in respect of the PD Obligation. Grace has accrued for those unresolved Other PD Claims that it believes are probable and estimable. Grace has not accrued for other unresolved or unasserted Other PD Claims as it does not believe that payment is probable.
All payments to the PD Trust required after the Effective Date are secured by the Company'sCompany’s obligation to issue 77,372,257 shares of Company common stock to the PD Trust in the event of default, subject to customary anti-dilution provisions.
In the 2015 first quarter, Grace finalized its accounting for emergence from bankruptcy and recorded a gain of $9.0 million reflecting the final resolution of certain bankruptcy liabilities.
This summary of the commitments and contingencies related to the Chapter 11 proceeding does not purport to be complete and is qualified in its entirety by reference to the plan of reorganization and the exhibits and documents related thereto, which have been filed with the SEC.SEC and are readily available on the internet at www.sec.gov.
Legacy Environmental Liabilities    Grace is subject to loss contingencies resulting from extensive and evolving federal, state, local and foreign environmental laws and regulations relating to its manufacturing operations. Grace has procedures in place to minimize such contingencies; nevertheless, it has liabilities associated with past operations and additional claims may arise in the future. To address its legacy liabilities, Grace accrues for anticipated costs of response efforts where an assessment has indicated that a probable liability has been incurred and the cost can be reasonably estimated. These accruals do not take into account any discounting for the time value of money.

Grace’s environmental liabilities are reassessed regularly and adjusted when circumstances become better defined or response efforts and their costs can be better estimated, typically as a matter moves through the life-cycle of environmental investigation and remediation. These liabilities are evaluated based on currently available information relating to the nature and extent of contamination, risk assessments, feasibility of response actions, and apportionment amongst other potentially responsible parties, all evaluated in light of prior experience.
At December 31, 2016, Grace's2018, Grace’s estimated liability for legacy environmental response costs totaled $66.3$126.4 million, compared with $55.2$70.3 million at December 31, 2015,2017, and was included in "other“other current liabilities"liabilities” and "other liabilities"“other liabilities” in the Consolidated Balance Sheets. These amounts are based on agreements in place or on Grace'sGrace’s estimate of costs where no formal remediation plan exists, yet there is sufficient information to estimate response costs.
Grace recorded pre-tax charges of $73.8 million, $24.4 million, and $29.2 million $6.4 million, and $14.7 million for legacy environmental matters in 2016, 2015,2018, 2017, and 2014,2016, respectively, which is included in "provision“provision for environmental remediation"remediation” in the Consolidated Statements of Operations. Net cash paid against previously established reserves in 2016, 2015, and 2014 were $18.1 million, $12.3 million, and $11.7 million, respectively. During 2014, claim payments of $76.5 million were made in connection with Grace's emergence from Chapter 11.

Vermiculite-Related Matters
Grace purchased a vermiculite mine in Libby, Montana, in 1963 and operated it until 1990. Vermiculite concentrate from the Libby mine was used in the manufacture of attic insulation and other products. Some of the vermiculite ore contained naturally occurring asbestos.
Grace is engaged with the U.S. Environmental Protection Agency (the "EPA"“EPA”) and other federal, state and local governmental agencies in a remedial investigation and feasibility study ("(“RI/FS"FS”) of the Libby mine and the surrounding area. Thisarea, known as Operable Unit 3 (“OU3”). The RI/FS will determine the specific areas within OU3 requiring remediation and will identify possible remedial action alternatives. Possible remedial actions within OU3 are wide-ranging, from institutional controls such as land use restrictions, to more active measures involving soil removal, containment projects, or other protective measures.
Grace expectsaccrued $70.2 million, $9.5 million, and $24.8 million in 2018, 2017, and 2016, respectively, for future costs related to vermiculite-related matters.
As part of the RI/FS process, Grace contracted an engineering and consulting firm to develop a recordrange of decisionpossible remedial alternatives and associated cost estimates for OU3. Based on this work, Grace recorded a pre-tax charge of $70.0 million in the 2018 third quarter for the estimated costs of remediation of OU3. Grace believes that this amount should provide for a protective remedy meeting the statutory requirements of the Comprehensive Environmental Response, Compensation, and Liability Act.
The estimated costs of remediation are preliminary and consist of several components, each of which may vary significantly as the remedial alternatives are further developed. It is reasonably possible that the ultimate costs of remediation could range between $30 million and $170 million. Grace is working closely with the EPA, and the ultimate remedy will be determined by the EPA after the RI/FS is finalized. Such remedy will be set forth in a Record of Decision (“ROD”) that is expected to be completed in 2018issued by the EPA during or 2019. When meaningful new information becomes available,after 2020. Costs associated with the more active remedial alternatives would be expected to be incurred over a decade or more. Grace will reevaluate its estimated liability foras remedial alternatives evolve based on further work by the costs for remediationengineering and consulting firm and discussions with the EPA as the RI/FS process moves toward a ROD. Depending on the remedial alternatives that the EPA selects in the ROD, the total cost of the mine and surrounding area and adjust its reserves accordingly.remediating OU3 may exceed Grace’s current estimate by material amounts.
The EPA is also investigating or remediating formerly owned or operated sites that processed Libby vermiculite into finished products. Grace is cooperating with the EPA on these investigation and remediation activities and has recorded a liability to the extent that its review has indicated that a probable liability has been incurred and the cost is estimable. These liabilities cover the estimated cost of investigations and, to the extent an assessment has indicated that remediation is necessary, the estimableestimated cost of response actions. Response actions typically involve soil excavation and removal, and replacement with clean fill. The EPA may commence additional investigations in the future at other sites that processed Libby vermiculite, but Grace does not believe,

based on its knowledge of prior and current operations and site conditions, that liability for remediation at such other sites is probable.
Grace accrued $24.8 million, $6.0 million, and $7.5 million in 2016, 2015, and 2014, respectively, for future costs related to vermiculite-related matters. More than half of the 2016 amount was for the completion of the RI/FS of the Libby mine and surrounding area, which is expected to be spent over the next three years. Grace'sGrace’s total estimated liability for response costs that are currently estimable for the Libby mine and surrounding area, and at vermiculite processing sites outside of Libby at December 31, 20162018 and 20152017, was $31.281.7 million and $18.725.8 million, respectively. It is probablepossible that Grace'sGrace’s ultimate liability for these vermiculite-related matters will exceed current estimates by material amounts.
Non-Vermiculite-Related Environmental Matters
During 2018, Grace accrued $3.6 million to increase non-vermiculite environmental reserves. During 2017, Grace accrued $14.9 million to increase non-vermiculite environmental reserves, including $7.2 million for ten years of operation and maintenance expenses following remediation at a former manufacturing site. At December 31, 20162018 and 2015, Grace's2017, Grace’s estimated legacy environmental liability for response costs at sites not related to its former vermiculite mining and processing activities was $35.1$44.7 million and $36.5$44.5 million, respectively. This liability relates to Grace'sGrace’s former businesses or operations, including its share of liability at off-site disposal facilities. Grace'sGrace’s estimated liability is based upon regulatory requirements and environmental conditions at each site. As Grace receives new information, its estimated liability may change materially.
Other Legacy LiabilitiesAs part of the process for renewing Grace’s permit for a dam on the Libby mine site, which expires in March 2019, the Montana Department of Natural Resources and Conservation is expected to require Grace to replace the dam spillway, which is deteriorating, with a new spillway. Grace constructed the dam in 1971 to prevent vermiculite ore tailings from moving into nearby creeks and rivers. Based on information provided by third-party consultants, the cost of the new spillway is estimated to be between $40 million and $45 million. Grace expects to record a liability for this project at the time the permit renewal is approved. Grace anticipates that approval of the renewal of such permit will occur in the first quarter of 2019. Construction of the new spillway is expected to take three to four years.
Commercial and Financial Commitments and Contingencies
Purchase Commitments    Grace uses purchase commitments to ensure supply and to minimize the volatility of major components of direct manufacturing costs including natural gas, certain metals, rare earths, and other materials. Such commitments are for quantities that Grace fully expects to use in its normal operations.
Guarantees and Indemnification Obligations    Grace is a party to many contracts containing guarantees and indemnification obligations. These contracts primarily consist of:
Product warranties with respect to certain products sold to customers in the ordinary course of business. These warranties typically provide that products will conform to specifications. Grace accrues a warranty liability on a transaction-specific basis depending on the individual facts and circumstances related to each sale. Both the liability and annual expense related to product warranties are immaterial to the Consolidated Financial Statements.

Performance guarantees offered to customers under certain licensing arrangements. Grace has not established a liability for these arrangements based on past performance.
Licenses of intellectual property by Grace to third parties in which Grace has agreed to indemnify the licensee against third party infringement claims.
Contracts providing for the sale or spin-off of a former business unit or product line in which Grace has agreed to indemnify the buyer or resulting entity against certain liabilities related to activities prior to the closing of the transaction, including environmental, liabilities.
Contracts related to the Separation in which Grace has agreed to indemnify GCP against liabilities related to activities prior to the closing of the transaction, including tax, employee, and environmentalemployee liabilities.

15. Stock Incentive Plans (Continued)

On May 2021.9, 2018, the Company’s stockholders approved the W. R. Grace & Co. 2018 Stock Incentive Plan. Under this new plan, stock options have a 10 year life. The Company began issuing stock-based compensation awards from this plan in the second half of 2018. The Company’s annual grant made in February 2018 was issued under the previous plan in which options have a 5 year life.
Previously outstanding stock-based compensation awards granted under equity compensation programs prior to the Separation and held by certain executives and employees were adjusted in 2016 to reflect the impact of the Separation on these awards. To preserve the aggregate intrinsic value of awards held prior to the Separation, as measured immediately before and immediately after the Separation, each holder of stock-based compensation awards generally received an adjusted award consisting of either (i) both a stock-based compensation award denominated in Company equity as it existed subsequent to the Separation and a stock-based compensation award denominated in GCP equity or (ii) solely a stock-based compensation award denominated in Company equity. In the Separation, the determination as to which type of adjustment applied to a holder’s previously outstanding award was based upon the date on which the award was originally granted under the equity compensation programs prior to the Separation. The adjustment of the original awards resulted in $0.6 million of incremental compensation cost.cost in 2016.

At December 31, 20162018, the weighted-average remaining contractual term of all options outstanding and exercisable was 2.542.11 years.
Options Granted     The Company granted approximately 0.4 million, 0.6 million, and 0.5 million nonstatutory stock options in 2016, 2015, and 2014, respectively, under the Stock Incentive Plans.
For the years ended December 31, 20162018, 20152017 and 20142016, the Company recognized non-cash stock-based compensation expense with respect to stock option grants of $6.05.8 million, $9.94.3 million and $12.06.0 million, respectively, which is included in "selling,“selling, general and administrative expenses"expenses” in the Consolidated Statements of Operations. The actual tax benefit realized from stock options exercised totaled $11.2$2.2 million, $3.3$7.4 million, and $2.5$11.2 million for the yearyears ended December 31, 2016, 20152018, 2017 and 2014,2016, respectively.
The Company values options using the Black-Scholes option-pricing model, which was developed for use in estimating the fair value of traded options. The risk-free rate is based on the U.S. Treasury yield curve published as of the grant date, with maturities approximating the expected term of the options. The expected term of the options is estimated using the simplified method as allowed by ASC 718-20, whereby the average between the vesting period and contractual term is used. TheFor options granted prior to 2018, the expected volatility was estimated using both actual stock volatility and the volatility of an industry peer group. The Company believes its actual stock volatility was not representative of future volatility during the time it was in Chapter 11. For options granted in 2018, Grace actual stock volatility was used. The following summarizes the weighted average assumptions used for estimating the fair value of stock options granted during 20162018, 20152017 and 20142016, respectively.

Total unrecognized stock-based compensation expense at December 31, 20162018, was $4.31.8 million, and the weighted-average period over which this expense will be recognized is 1.00.8 of a year.
Restricted Stock and Performance Based Units    During 2018 the Company granted 86,698 RSUs and 93,216 PBUs under the Company’s Long-term Incentive Plan (“LTIP”). During 2017 the Company granted 57,600 RSUs and 115,158 PBUs under the LTIP. During 2016 the Company granted 77,358 Restricted Stock Units (RSUs)RSUs and 124,952 Performance Based Units (PBUs) under the Company's Long-term Incentive Plan (LTIP). During 2015 the Company granted 123,846 RSUs and 1,864 PBUs under the LTIP. During 2014 the Company granted 110,993 PBUs under the LTIP. The PBUs that were granted in 2014 were converted to RSUs in2018, 2017, and 2016, as a result of the Separation. During 2016, 2015,awards covering 44,279, 16,395, and 2014, 15,197 10,641, and 8,570 awardsshares were forfeited, respectively. The awardsPBUs cliff vest onafter the completion of the performance periods ending December 31, 2018, 2017,2020, 2019, and 2016, subject to continued employment through the payment date,2018, and have a weighted average grant date fair value of $68.65, $67.95,$67.39, $71.37 and $67.95$68.50, respectively. The Company anticipates that approximately 67%RSUs vest in three equal annual installments and have a weighted average grant date fair value of $67.54, $71.37, and $68.90, respectively. Vesting for all awards is subject to continued employment through the awards granted in 2016 will be settled in common stock, and approximately 33% will be settled in cash, assuming full vesting. The Company anticipates that approximately 53% of the PBUs granted in 2015 will be settled in common stock andpayment

The Company anticipates that approximately 47%64% of the awards granted in 2018 will be settled in common stock and approximately 36% will be settled in cash, assuming full vesting. The Company anticipates that approximately 53%65% of the PBUsawards granted in 20142017 will be settled in common stock and approximately 47%35% will be settled in cash, assuming full vesting. The Company anticipates that approximately 67% of the awards granted in 2016 will be settled in common stock and approximately 33% will be settled in cash, assuming full vesting.
PBUs and RSUs are recorded at fair value at the date of grant. The common stock settled portion is considered an equity award with the payout being valued based on the Company’s stock price on the grant date. The cash settled portion of the award is considered a liability award with payout being remeasured each reporting period based on the Company’s current stock price. PBU equity and cash awards are remeasured each reporting period based on the expected payout of the award, which may range from 0% to 200% of the targets for such awards; therefore, these portions of the awards are subject to volatility until the payout is finally determined at the end of the performance period. During 2016, 2015,2018, 2017, and 2014,2016, the Company recognized $8.6$13.2 million, $5.8$10.3 million, and $3.5$8.6 million in compensation expense for these awards. As of December 31, 2016, $12.72018, $9.5 million of total unrecognized compensation expense related to the awards is expected to be recognized over the remaining weighted-average service period of 1.71.5 years.

(1)Under the modified retrospective method, prior-period information has not been adjusted and continues to be reported in accordance with Grace’s historical accounting under ASC 605.
Contract Balances    Grace invoices customers for product sales once performance obligations have been satisfied, generally at the point of delivery, at which point payment becomes unconditional. Accordingly, Grace's product sales contracts generally do not give rise to material contract assets or liabilities under ASC 606; however, from time to time certain customers may pay in advance. In the technology licensing business, Grace invoices licensees based on milestones achieved but has obligations to provide services in future periods, which results in contract liabilities.
The following table presents Grace’s deferred revenue balances as of December 31, 2018 and 2017:
 December 31,
(In millions)2018 2017
Current$40.6
 $19.5
Noncurrent29.2
 14.9
Total$69.8
 $34.4
These amounts are included as deferred revenue in “other current liabilities” and “other liabilities” in Grace's Consolidated Balance Sheets. Grace records deferred revenues when cash payments are received or due in advance of performance. The increase in deferred revenue reflects cash payments from customers received or due in advance of satisfying performance obligations, offset by $16.6 million of revenue recognized that was included in the deferred revenue balance as of December 31, 2017, and the $3.2 million cumulative adjustment recorded to “retained earnings” as part of the adoption of ASC 606.
The noncurrent portion of the technology licensing revenue will be recognized as performance obligations under the technology licensing agreements are satisfied; the noncurrent balance is expected to be recognized over the next four years.
Remaining performance obligations represent the estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied). The aggregate amount of the transaction price allocated to remaining performance obligations for such contracts with a duration of more than one year was approximately $103 million as of December 31, 2018, and includes certain amounts reported as deferred revenue above. In accordance with the practical expedient in ASC 606-10-50-14, Grace does not disclose information about remaining performance obligations that have original expected durations of one year or less, which generally relate to customer prepayments on product sales and are generally satisfied in less than one year. Grace expects to recognize revenue related to remaining performance obligations over several years, as follows:

Thereafter through 2025 25%
  100%
For the years ended December 31, 2018, 2017, and 2016, revenue recognized from performance obligations related to prior periods was not material. Grace has not capitalized any costs to obtain or fulfill contracts with customers under ASC 606. No material impairment losses have been recognized on any receivables or contract assets arising from contracts with customers.
18. Segment Information
Grace is a global producer of specialty chemicals and specialty materials. Grace'sGrace’s two reportable business segments are Grace Catalysts Technologies and Grace Materials Technologies. Grace Catalysts Technologies includes catalysts and related products and technologies used in refining, petrochemical and other chemical manufacturing applications. Advanced Refining Technologies (ART)(“ART”), Grace'sGrace’s joint venture with Chevron Products Company, a division of Chevron U.S.A. Inc. ("Chevron"(“Chevron”), is managed in this segment. (See Note 18.19.) Grace Catalysts Technologies comprises two operating segments, Grace Refining Technologies and Grace Specialty Catalysts, which are aggregated into one reportable segment based upon similar economic characteristics, the nature of the products and production processes, type and class of customer, and channels of distribution. Grace Materials Technologies includes specialty materials, including silica-based and silica-alumina-based materials, used in coatings, consumer, industrial,consumer/pharma, chemical process, and pharmaceuticalcoatings applications. The table below presents information related to Grace'sGrace’s reportable segments. Only those corporate expenses directly related to the reportable segments are allocated for reporting purposes. All remaining corporate items are reported separately and labeled as such.
Grace excludes defined benefit pension expense from the calculation of segment operating income. Grace believes that the exclusion of defined benefit pension expense provides a better indicator of its reportable segment performance as defined benefit pension expense is not managed at a reportable segment level.
Grace defines Adjusted EBIT to be income from continuing operations attributable to W. R. Grace & Co. shareholders adjusted for interest income and expense; income taxes; costs related to Chapter 11, and legacy product, environmental and environmental;other claims; restructuring and repositioning expenses and asset impairments; pension costs other than service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; income and expense items related to divested businesses, product lines, and certain other investments; gains and losses on sales of businesses, product lines, and certain other investments; third-party acquisition-related costs and the amortization of acquired inventory fair value adjustment; and certain other items that are not representative of underlying trends.

The business is included in the Specialty Catalysts operating segment of the Catalysts Technologies reportable segment. The acquisition is complementary to Grace's existing specialty catalysts business and strengthens Grace's commercial relationships, catalysts technology portfolio, and manufacturing network.
The acquisition purchase price has been preliminarily allocated to the tangible and identifiable intangible assets and liabilities acquired based on their estimated fair values at the acquisition date in accordance with ASC 805 "Business“Business Combinations."

21. Discontinued Operations
As a result of the Separation and Distribution, GCP is now an independent public company and its common stock is listed under the symbol “GCP” on the New York Stock Exchange. Grace does not beneficially own any shares of GCP common stock and will not consolidate the financial results of GCP in its future financial reporting, as GCP is no longer a related party to Grace subsequent to the Separation. GCP’s historical financial results through the Distribution Date are reflected in Grace’s Consolidated Financial Statements as discontinued operations.
Separation and Distribution Agreement    Prior to the completion of the Separation and the Distribution, W. R. Grace & Co., Grace–Conn. and GCP entered into a Separation and Distribution Agreement and certain related agreements that govern the post-Separation relationship between Grace and GCP. The Separation and

Distribution Agreement identifies the transfer of Grace'sGrace’s assets and liabilities that are specifically identifiable or otherwise allocable to GCP, the elimination of Grace’s equity interest in GCP, the removal of certain non-recurring separation costs directly related to the Separation and Distribution, the cash distribution from GCP to Grace, and the reduction in Grace'sGrace’s debt using the cash received from GCP, and it provides for when and how these transfers, assumptions and assignments have occurred or will occur.
Tax Sharing Agreement      W. R. Grace & Co., Grace–Conn. and GCP entered into a Tax Sharing Agreement that generally governs the parties’ respective rights, responsibilities and obligations after the Distribution with respect to taxes (including taxes arising in the ordinary course of business and taxes, if any, incurred as a result of any failure of the Distribution and certain related transactions to qualify under Sections 355 and certain other relevant provisions of the Internal Revenue Code (the “Code”)), tax attributes, the preparation and filing of tax returns, tax elections, tax contests, and certain other tax matters.
In addition, the Tax Sharing Agreement imposes certain restrictions on GCP and its subsidiaries (including restrictions on share issuances, business combinations, sales of assets and similar transactions) that are designed to preserve the qualification of the Distribution and certain related transactions under Sections 355 and certain other relevant provisions of the Code. The Tax Sharing Agreement provides special rules that allocate tax liabilities in the event the Distribution, together with certain related transactions, does not so qualify. In general, under the Tax Sharing Agreement, each party is expected to be responsible for any taxes imposed on, and certain related amounts payable by, GCP or Grace that arise from the failure of the Distribution and certain related transactions, to qualify under Sections 355 and certain other relevant provisions of the Code, to the extent that the failure to so qualify is attributable to actions, events or transactions relating to such party’s respective stock, assets or business, or a breach of the relevant representations or covenants made by that party in the Tax Sharing Agreement.
The foregoing is a summary of the Separation and Distribution Agreement and the Tax Sharing Agreement. Grace has filed the full texts of the Separation and Distribution Agreement and thea related Tax Sharing Agreement with the SEC, which are readily available on the Internet at www.sec.gov.

2016 Events
On June 30, 2016, we completed the acquisition of the assets of the BASF Polyolefin Catalysts business (the "polyolefin catalysts acquisition"), which included technologies, patents, trademarks, and production plants in Pasadena, Texas, and Tarragona, Spain. We added the following technologies to our catalysts portfolio: (1) LYNX® high-activity polyethylene (PE) catalyst technologies used commercially in slurry processes for the production of high-density PE resins such as bimodal film and pipe, and (2) LYNX® polypropylene (PP) catalyst technologies used commercially in all major PP process technologies including slurry, bulk loop, stirred gas, fluid gas, and stirred bulk. The acquisition also will provide us with significant additional flexibility and capacity for our global polyolefin catalysts manufacturing network.
In 2016, we exited certain product lines that were previously part of our Discovery Sciences product group included in our Grace Materials Technologies operating segment, as these product lines no longer fit into our strategic growth plans. As part of the exit, we sold certain assets to unaffiliated buyers for aggregate proceeds of $12.9 million.
On January 27, 2016, we entered into a separation agreement with GCP Applied Technologies Inc., then a wholly-owned subsidiary of Grace ("GCP"), pursuant to which we agreed to transfer our Grace Construction Products operating segment and the packaging technologies business of our Grace Materials Technologies operating segment to GCP (the "Separation"). We completed the Separation on February 3, 2016, by means of a pro rata distribution to Company stockholders of all of the outstanding shares of GCP common stock (the "Distribution"), with one share of GCP common stock distributed for each share of Company common stock held as of the close of business on January 27, 2016. As a result of the Distribution, GCP became an independent public company. GCP’s historical financial results through the Distribution Date are reflected in our Consolidated Financial Statements as discontinued operations.$4.14 per diluted share.
Summary Description of Business
We are engaged in specialty chemicals and specialty materials businesses on a worldwide basis through our two reportable segments, Grace Catalysts Technologies and Grace Materials Technologies. See Item 1 (Business—Business Overview) of this Report for a summary description of our core business.
Analysis of Operations
We have set forth in the table below our key operating statistics with percentage changes for the years ended December 31, 20162018, 20152017, and 20142016. Please refer to this Analysis of Operations when reviewing this Management'sManagement’s Discussion and Analysis of Financial Condition and Results of Operations. In the table we present financial information in accordance with U.S. GAAP, as well as the non-GAAP financial information described below. We believe that the non-GAAP financial information provides useful supplemental information about the performance of our businesses, improves period-to-period comparability and provides clarity on the information

Table of Contents

our management uses to evaluate the performance of our businesses. In the table, we have provided reconciliations of these non-GAAP financial measures to the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP. The non-GAAP financial measures should not be considered as a substitute for financial measures calculated in accordance with U.S. GAAP, and the financial results calculated in accordance with U.S. GAAP and reconciliations from those results should be evaluated carefully.
We define Adjusted EBIT (a non-GAAP financial measure) to be income from continuing operations attributable to W. R. Grace & Co. shareholders adjusted for interest income and expense; income taxes; costs related to Chapter 11, and legacy product, environmental and environmental;other claims; restructuring and repositioning expenses and asset impairments; pension costs other than service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; income and expense items related to divested businesses, product lines, and certain other investments; gains and losses on sales of businesses, product lines, and certain other investments; third-party acquisition-related costs and the amortization of acquired inventory fair value adjustment; and certain other items that are not representative of underlying trends.
We define Adjusted EBITDA (a non-GAAP financial measure) to be Adjusted EBIT adjusted for depreciation and amortization.
We define Adjusted EBIT Return On Invested Capital (a non-GAAP financial measure) to be Adjusted EBIT (on a trailing four quarters basis) divided by the sum of net working capital, properties and equipment and certain other assets and liabilities.

Table of Contents

We define Adjusted Gross Margin (a non-GAAP financial measure) to be gross margin adjusted for pension-related costs included in cost of goods sold and the amortization of acquired inventory fair value adjustment.
We define Adjusted Earnings Per Share (EPS) (a non-GAAP financial measure) to be diluted EPS from continuing operations adjusted for costs related to Chapter 11, and legacy product, environmental and environmental;other claims; restructuring and repositioning expenses and asset impairments; pension costs other than service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; income and expense items related to divested businesses, product lines, and certain other investments; gains and losses on sales of businesses, product lines and certain other investments; third-party acquisition-related costs and the amortization of acquired inventory fair value adjustment; certain other items that are not representative of underlying trends; and certain discrete tax items.items; and income tax expense related to historical tax attributes.
We define Net Sales, constant currency (a non-GAAP financial measure) to be the period-over-period change in net sales calculated using the foreign currency exchange rates that were in effect during the previous comparable period.
We use Adjusted EBIT as a performance measure in significant business decisions and in determining certain incentive compensation. We use Adjusted EBIT as a performance measure because it provides improved period-to-period comparability for decision making and compensation purposes, and because it better measures the ongoing earnings results of our strategic and operating decisions by excluding the earnings effects of our Chapter 11 proceedings, legacy product, environmental, and environmental matters,other claims; restructuring and repositioning activities,activities; divested businesses, andbusinesses; the effects of acquisitions.acquisitions; and certain other items that are not representative of underlying trends.
We use Adjusted EBITDA, Adjusted EBIT Return On Invested Capital, Adjusted Gross Margin, and Adjusted EPS as performance measures and may use these measures in determining certain incentive compensation. We use Adjusted EBIT Return On Invested Capital in making operating and investment decisions and in balancing the growth and profitability of our operations.
We use Net Sales, constant currency as a performance measure to compare current period financial performance to historical financial performance by excluding the impact of foreign currency exchange rate fluctuations that are not representative of underlying business trends and are largely outside of our control.
Adjusted EBIT, Adjusted EBITDA, Adjusted EBIT Return On Invested Capital, Adjusted Gross Margin, and Adjusted EPS, and Net Sales, constant currency are non-GAAP financial measures; do not purport to represent income measures as defined under U.S. GAAP,GAAP; and should not be used as alternatives to such measures as an indicator of our performance. These measures are provided to investors and others to improve the period-to-period comparability and peer-to-peer comparability of our financial results, and to ensure that investors understand the information we use to evaluate the performance of our businesses. They distinguish the operating results of Grace’s current business base from the costs of Grace’s legacy product, environmental and other claims; restructuring and repositioning activities; divested businesses; and certain other items. These measures may have material limitations due to the exclusion or inclusion of amounts that are included or excluded, respectively, in the most directly comparable measures calculated and presented in accordance with U.S. GAAP, and thus investors and others should review carefully the financial results calculated in accordance with U.S. GAAP.
Adjusted EBIT has material limitations as an operating performance measure because it excludes costs related to Chapter 11 and legacy product, environmental and environmental mattersother claims, and may exclude income and expenses from restructuring and repositioning activities and divested businesses, which historically have been material components of our net income. Adjusted EBITDA also has material limitations as an operating performance measure because it excludes the impact of depreciation and amortization expense. Our business is substantially

dependent on the successful deployment of capital, and depreciation and amortization expense is a necessary element of our costs. We compensate for the limitations of these measurements by using these indicators together with net income as measured under U.S. GAAP to present a complete analysis of our results of operations. Adjusted EBIT and Adjusted EBITDA should be evaluated together with net income and net income attributable to Grace shareholders, measured under U.S. GAAP, for a complete understanding of our results of operations.

Grace Income From Continuing Operations
chart-a529d99957b3535589f.jpg
Income from continuing operations was $107.0$167.6 million for 2016, a decrease of 13.7%2018 compared with $124.0$11.2 million for the prior year. The increase was primarily due to the $143.0 million provisional tax charge for the estimated impacts of the U.S. Tax Cuts and Jobs Act of 2017 (the “TCJA”), which was recorded in 2017. This was partially offset by higher restructuring and repositioning expenses and a higher provision for environmental remediation in 2018, which was primarily due to the $70.0 million charge for the estimated costs of future remediation-related activities at the Libby, Montana, mine site (see Note 10 to the Consolidated Financial Statements).
Income from continuing operations was $11.2 million for 2017 compared with $107.0 million for the prior year. The decrease was primarily due to a higher pension mark-to-market adjustment, a higher provision for environmental remediation primarily related to vermiculite-related matters, higher restructuring and repositioning expenses, and a loss on early extinguishment of debtincome taxes due to a $143.0 million provisional charge for the accelerated amortizationestimated impacts of capitalized financing costs associated with the pay down of $600 million of debtTCJA (see Note 7 to the Consolidated Financial Statements) and an accounts receivable reserve for a customer in the 2016 first quarter,Venezuela, partially offset by lower corporate costs, higher segment operating income, and lower net interest expenses resulting from the pay-down of debt. Income in the prior year included a $9.0 million gain reflecting the final resolution of certain bankruptcy liabilities, as well as a gain on the sale of an operating asset.
Income from continuing operations was $124.0 million for 2015, an increase of 6.0% compared with $117.0 million for the prior year. The increase was primarily due to a lower pension mark-to-market adjustment, a lower provision for environmental remediation, and lower Chapter 11-related expenses, partially offset by a provision for income taxes in 2015 compared with a benefit from income taxes in 2014, lower segment operating income, higher restructuring and repositioning expenses, and a lower gain relatedpension mark-to-market adjustment.
During the 2018 first quarter, we completed a study to evaluate the terminationuseful lives of our operating machinery and curtailmentequipment, including a review of postretirement benefit plans.historical asset retirement data as well as review and analysis of relevant industry practices. As a result of this study, effective January 1, 2018, we revised the accounting useful lives of

certain machinery and equipment, which was determined to be a change in accounting estimate and is being applied prospectively. As a result of this change in accounting estimate, depreciation expense with respect to such machinery and equipment was reduced by $23.5 million, resulting in an increase to net income of $18.0 million or $0.27 per diluted share for the year ended December 31, 2018. Estimated useful lives for operating machinery and equipment, which previously ranged from 3 to 10 years, now range from 5 to 25 years.

Adjusted EBIT Return On Invested Capital
chart-1f4b603d940d5093986.jpg
Adjusted EBIT Return On Invested Capital for 20162018 was 24.3%20.9% on a trailing four quarters basis, a decrease from 24.4%compared with 2017 and 26.1%2016 on the same basis, for 2015 and 2014, respectively. The decrease in 2016 was primarily due to the polyolefin catalysts acquisition. The acquisition, which was completed on June 30, 2016,April 3, 2018, increased invested capital at that date, butwhile Adjusted EBIT includes only twothree quarters of earningsincome from the acquired business. The decrease in 2015 was primarily due to lower Adjusted EBIT.
We manage our operations with the objective of maximizing sales, earnings and cash flow over time. Doing so requires that we successfully balance our growth, profitability and working capital and other investments to support sustainable, long-term financial performance. We use Adjusted EBIT Return On Invested Capital as a performance measure in evaluating operating results, in making operating and investment decisions, and in balancing the growth and profitability of our operations.
Grace Value Model
In March 2018, we introduced investors to the Grace Value Model (“GVM”), our framework for creating and delivering value to customers, investors, and employees. At the company level, we create value through our focused portfolio, strong strategic position, and disciplined capital allocation. At the business level, we create value through customer-driven innovation, commercial excellence, and operating excellence. Great talent, our high-performance culture, and integrated business management processes support all of our activities and are a source of competitive advantage.
The GVM framework also encompasses our multi-year initiatives to transform our manufacturing and business processes to extend our competitive advantages and improve our cost position. We expect to significantly improve our manufacturing performance, reduce our manufacturing costs, and improve our integrated business management capabilities. We also expect to invest significant capital in our manufacturing plants to

accelerate growth and improve manufacturing performance. Our investments in commercial excellence are yielding positive results in account management, pipeline management and conversion, and pricing.
Segment Overview—Grace Catalysts Technologies
Following is an overview of the financial performance of Catalysts Technologies for the years ended December 31, 20162018, 20152017, and 20142016.
Net Sales—Grace Catalysts Technologies
chart-b473ddd7a4f2520e8e6.jpg
Sales were $1,163.7$1,463.5 million for 2016,2018, an increase of 0.1%14.6% compared with the prior year. The increase was due to higher sales volumes (+12.1%), improved pricing (+1.6%), and favorable currency translation (+0.9%). Higher sales were driven by the 2018 polyolefin catalysts acquisition (+6.8%) and growth in the existing businesses across all regions except Asia Pacific, driven by higher demand from new and existing customers and higher licensing revenues, improved pricing, and favorable currency translation as the U.S. dollar weakened against multiple currencies, especially the euro, compared with the prior year.
Sales were $1,276.5 million for 2017, an increase of 9.7% compared with the prior year. The increase was due to higher sales volumes (+9.7%), and favorable currency translation (+0.3%), partially offset by lower pricing (-1.2%(-0.3%) primarily due to customer mix. Higher sales volumes were driven by higher demand, primarily in Asia Pacific, and unfavorable currency translation (-0.3%).the full-year benefit of the 2016 polyolefin catalysts acquisition. Specialty catalystsCatalysts sales volumes increased due to the 2016 polyolefin catalysts acquisition and organic growth in the existing businesses driven by higher demand in all regions exceptmarkets. Refining Catalysts sales volumes increased primarily in Asia Pacific, due to demand for new products, bid business, and new customer acquisition. Sales volumes in Latin America withdecreased primarily due to a delay in contract renewals in the majority of the increase coming from Europe. Sales volumes were higher in Asia despite declines in China as customers reduced inventories to align withregion and lower projected growth rates and decreased demand for chemical catalysts. The higher specialty catalyst sales volumes reflect a favorable impact related to the polyolefin catalysts acquisition. In January 2016, we reduced 10,000 tons of our least efficient capacity at our Curtis Bay plant, which contributed to the decline in refining catalysts sales volumes. Reductions in customer trials and higher refinery turnarounds also impacted sales volumes of refining catalysts. Unfavorableinto Venezuela. Favorable currency translation primarily affected refining catalysts.
Sales were $1,162.1 million for 2015, a decrease of 6.8%both product groups as the U.S. dollar weakened against multiple currencies, especially the euro, compared with the prior year. The decrease was due to unfavorable currency translation (-4.8%), lower sales volumes (-1.7%) and lower pricing (-0.3%). Refining catalysts sales volumes decreased primarily due to the transition in commercial positions undertaken earlier in the year to strengthen our business in North America, the Middle East, and Asia, and the delayed timing of some new and existing customers increasing order volumes. Specialty catalysts sales volumes increased due to increased order volumes at new customers and new product penetration. Unfavorable currency translation was due to the strength of the U.S. dollar against the other currencies in which we do business, primarily the euro.

Sales were $434.9468.6 million for 20162018, a decreasean increase of 6.7%6.5% compared with the prior year. The decreaseincrease was due to lowerhigher sales volumes (-5.6%(+3.1%), favorable currency translation (+1.8%), and improved pricing (+1.6%). The increase in sales volumes was primarily driven by higher consumer/pharma and coatings sales in Europe, higher chemical process and coatings sales in North America, and higher sales across all product groups in Latin America. The remainder of the increase was driven by improved pricing across all regions and favorable currency translation as the U.S. dollar weakened against multiple currencies, especially the euro, compared with the prior year. Materials Technologies is our reportable segment most sensitive to changes in the euro.
Sales were $440.0 million for 2017, an increase of 1.2% compared with the prior year. The increase was due to favorable currency translation (+1.1%) and unfavorable currency translation (-1.2%higher sales volumes (+0.3%), partially offset by improvedlower pricing (+0.1%(-0.2%).

Sales were $466.1 million for 2015, a decrease of 8.7%half and lower pharmaceutical fine chemicals sales in North America. Favorable currency translation was due to the U.S. dollar weakening against multiple currencies, especially the euro, compared with the prior year. The decrease was due to unfavorable currency translation (-9.9%), partially offset by improved pricing (+0.7%) and higher sales volumes (+0.5%). Unfavorable currency translation was primarily in Europe and the emerging regions, as the dollar strengthened against the euro and other currencies. Sales volumes increased as growth in EMEA offset declines in other regions.

Corporate costs for 20152017 decreasedincreased 16.2% compared with the prior year, primarily due to the salea favorable settlement of an operatinginsurance claim in 2016 and higher incentive compensation expense in 2017.
Restructuring and Repositioning Expenses
During 2018, we incurred $14.0 million of restructuring expenses primarily related to the closure of two smaller manufacturing plants, the activities from which have been moved to larger, more cost-effective plants as part of our strategy to capture synergies from our recent Catalysts Technologies acquisitions. Restructuring expenses of $11.5 million in 2017 primarily related to workforce reduction programs in our manufacturing, supply chain, finance and IT functions. Restructuring expenses of $24.3 million in 2016 related to workforce reductions and the exit of certain non-strategic product lines in Materials Technologies. Substantially all costs related to the restructuring programs are expected to be paid by December 31, 2021, but could be paid earlier subject to negotiations around certain plant exit costs.
Repositioning expenses included in continuing operations for the years ended December 31, 2018, 2017, and 2016 were $32.4 million, $15.2 million, and $14.3 million respectively. Expenses incurred in 2018 primarily include $13.7 million of third-party costs related to a multi-year program to transform Grace’s manufacturing and

Expenses incurred in 2017 primarily related to third-party costs associated with productivity and transformation initiatives, as well as costs related to the Separation. Expenses incurred in 2016 primarily related to the Separation. Excluding asset write-offs and stock compensation costs, substantially all of these costs have been or are expected to be settled in 2015cash by December 31, 2019.

Defined Benefit Pension Expense
Defined benefit pension expense includes costs under U.S. and non-U.S. defined benefit pension plans that provide benefits to business segment and corporate employees, as well as retirees and former employees of divested businesses where we retained these obligations.
Under mark-to-market accounting, our pension costs consist of two elements: 1) "certain“certain pension costs"costs”—ongoing costs recognized quarterly, which include service and interest costs, expected returns on plan assets, and amortization of prior service costs/credits; and 2) "pension“pension mark-to-market adjustment and other related costs, net"net”—mark-to-market gains and losses recognized annually in the fourth quarter, or at an interim period should a significant event occur, resulting from changes in actuarial assumptions, such as discount rates and the difference between actual and expected returns on plan assets.
Certain pension costs were $15.9 million, $13.0 million and $12.3 million $20.4 millionfor 2018, 2017 and $24.5 million for 2016, 2015 and 2014, respectively. As of December 31, 2015, we changed the approach usedThe increases were primarily due to determine the service and interest cost components of defined benefit pension expense. Previously, we estimated service and interest costs using a single weighted averagedecrease in discount rate derived from the same yield curve used to measure the projected benefit obligation. For 2016, we elected to measure service and interest costs by applying the specific spot rates along that yield curve to the plans’ liability cash flows. We believe the new approach provides a more precise measurement of service and interest costs by aligning the timing of the plans’ liability cash flows to the corresponding spot rates on the yield curve. This change did not affect the measurement of the projected benefit obligation as of December 31, 2015. We consider this a change in accounting estimate, which is being accounted for prospectively as of January 1, 2016.

These costs are reported in "cost of goods sold" and in "selling, general and administrative expenses”“other (income) expense, net” in our Consolidated Financial Statements based uponStatements. The 2018 mark-to-market pension income of $15.2 million was primarily due to the functionsincrease in discount rates used to value the projected benefit obligations of our plans from year-end 2017 to year-end 2018, partially offset by lower than expected return on assets.

The 2014 mark-to-market pension expense of $137.6 million was primarily due to the decrease in discount rates from year-end 2013 to year-end 2014 and the impact of adopting new mortality assumptions, partially offset by higher than expected return on assets in the U.S.
Interest and Financing Expenses
Net interest and financing expenses were $80.5$78.5 million for 2016,2018, flat compared with 2017. Interest and financing expenses were $78.5 million for 2017, a decrease of 18.8%2.5% compared with 2015,2016, primarily due to voluntary prepayments related toof our term loans in February and March 2016. Interest and financing expenses were $99.1 million for 2015, a decrease of 18.7% compared with 2014, due to reduced interest accretion on deferred payment obligations due to the settlement of the PI deferred payment obligation during the 2014 third quarter,2016, partially offset by higher interest expense in 2015 for new debt incurred in 2014 in connection withdue to borrowings on our emergence from Chapter 11.floating rate term loans and revolving credit facility.

Income Taxes
Income tax expense (benefit) for 2018, 2017 and 2016 2015 and 2014 was $59.0$78.1 million, $69.8$200.5 million and $(12.4)$59.0 million, respectively, on income from continuing operations before income taxes of $166.0$244.9 million,, $193.7 $210.9 million and $104.5$166.0 million in 2016, 20152018, 2017 and 2014,2016, respectively.
Our 20162018 effective tax rate of approximately 36%31.9% was higher than the 35%21% U.S. statutory rate. The higher rate was primarily caused by recognition of the GILTI tax that could not be offset with a corresponding GILTI deduction due to $4.7Grace utilizing NOLs in 2018. Once we have fully utilized our NOLs, we will be able to take advantage of the GILTI deduction that is currently limited due to NOL utilization. The geographic mix of income also contributed to the higher rate since the statutory rates in effect for our foreign subsidiaries exceed the 21% U.S. statutory rate.
Our 2017 effective tax rate includes $143.0 million in charges for local and state income taxes, a $2.5 millionincrease in valuation allowance, and $2.5 millionrelated to non-deductible expenses, partially offset by $6.8 million of lower taxes in non-U.S. jurisdictions, $6.7 million in share based compensation deductions, and $2.6 million in adjustments to unrecognized tax benefits.
Our 2015the TCJA. The effective tax rate without the impact of approximately 36%the TCJA was higher than the 35% U.S. statutory rate primarily due to $2.9 million in charges for local and state income taxes, $1.7 million for adjustments to unrecognized tax benefits, $1.7 million related to repatriated foreign earnings, and $0.9 million related to non-deductible expenses, partially offset by $3.0 million due to lower taxes in non-U.S. jurisdictions and $1.6 million for the release of a state valuation allowance.
Our 2014 effective tax rate of approximately (12)% was27.3%, lower than the 35% U.S. statutory rate, primarily due to benefits recognized during the year including $57.9 milliongeographic mix of benefits associated withincome and the releaseR&D credit.
Our 2016 effective tax rate of reserves for unrecognized tax benefits, $5.1 million related to repatriated foreign earnings,35.5% was slightly higher than the 35% U.S. statutory rate. The benefit from the geographic mix of income and $3.0 million due to lower taxes in non-U.S. jurisdictions, partiallystock compensation windfall was nearly fully offset by $9.6 million in charges for state and local income taxes and $4.1 million related to non-deductible expenses.other permanent items.
See Note 7 to the Consolidated Financial Statements for additional information regarding income taxes.
Financial Condition, Liquidity, and Capital Resources
Following is an analysis of our financial condition, liquidity and capital resources at December 31, 20162018.
Our principal uses of cash are generally capital investments and acquisitions,acquisitions; working capital investments,investments; compensation paid to employees, including contributions to our defined benefit pension plans and defined contribution plans; the repayment of debt and interest payments thereon; and the return of cash to shareholders through repurchase of shares and dividends.
In January 2015, we completed the initial $500 million share repurchase program authorized by our Board of Directors following emergence from bankruptcy, and the Board of Directors authorized an additional share repurchase program of up to $500 million. Under this additional program, during 2016 we repurchased 2,775,297 shares of Company common stock for $195.1 million. As of December 31, 2016, $33.9 million remained under this authorization. On February 8, 2017, we announced that the Board of Directors had authorized a new share repurchase program of up to $250 million.

In the 2016 second quarter, Under this program, during 2018 we began to pay a quarterly cash dividend, at an annual rate of $0.68 per sharerepurchased 1,171,141 shares of Company common stock. stock for $80.0 million. As of December 31, 2018, $138.9 million remained under the current authorization.
We paid cash dividends of $36.0$64.6 million during 2016.2018. On February 8, 2017,2018, we announced that the Board of Directors had approved an increase in the annual dividend rate, from $0.84 to $0.84$0.96 per share of Company common stock, effective with the dividend paid March 22, 2018. On February 7, 2019, we announced that the Board of Directors had approved a further increase to $1.08 per share of Company common stock.
We believe that the cash we expect to generate during 20172019 and thereafter, together with other available liquidity and capital resources, are sufficient to finance our operations, growth strategy, share repurchase program and expected dividend payments, and meet our debt and pension obligations.
During the 2015 fourth quarter, to permit the Separation,On April 3, 2018, we entered into an amendmentthe Credit Agreement, which provides for new secured credit facilities, consisting of:
(a)a $950 million term loan due in 2025, with interest at LIBOR +175 basis points, and
(b)a $400 million revolving credit facility due in 2023, with interest at LIBOR +175 basis points.
We used the proceeds from the term loan to repay in full the outstanding borrowings of $507.0 million under our 2014 credit agreement, to fund the 2018 polyolefin catalysts acquisition for $418.0 million, and to make a voluntary $50.0 million accelerated contribution to our U.S. qualified pension plans. See Note 5 to the Consolidated Financial Statements for additional information related to the Credit Agreement. The amendment, which became effective upon completion of the Separation, also reduced the revolving credit facility to $300 million and extended its term to November 1, 2020. In connection with the Separation, GCP distributed $750 million to Grace. Using a portion of those proceeds, we repaid $600 million of our euro and U.S. dollar term loans. The Separation had no impact on payment or other terms of the Notes, and they remain our obligations.
Cash Resources and Available Credit Facilities
At December 31, 20162018, we had available liquidity of $384.4$606.7 million, consisting of $90.6200.5 million in cash and cash equivalents ($23.9100.5 million in the U.S.), $257.2$367.6 million available under theour revolving credit facility, and $36.638.6 million of available liquidity under various non-U.S. credit facilities. The $300$400 million revolving credit facility includes a $150$100 million sublimit for letters of credit.

Our non-U.S. credit facilities are extended to various subsidiaries that use them primarily to issue bank guarantees supporting trade activity and to provide working capital during occasional cash shortfalls. Our credit facility in Germany is secured by third-party accounts receivable, with availability determined on the basis of eligible outstanding receivables. We generally renew these credit facilities as they expire.

We paid cash dividends of $64.6 million in 2018, compared with $57.3 million in 2017 and $36.0 million in 2016. In 2016, we received a $750 million distribution of cash from GCP, of which we used $600 million was used to pay down our euro and U.S. dollar term loans in the first quarter. Cash paid for repurchases of common stock in 2016 was $195.1 million, compared with $301.5 million in 2015. In 2016, we also paid cash dividends of $36.0 million.
Net cash used for financing activities in 2015 was $40.5 million compared with net cash provided by financing activities of $864.2 million in the prior year. The change in cash provided by financing activities is primarily due to new debt issued in 2014, partially offset by lower 2015 payments to repurchase common stock under our share repurchase program.
Included in net cash provided by (used for) operating activities from continuing operations are Chapter 11 and legacy product and environmental expenses paid of $24.6 million, $507.4 million and $1,992.5 million; and restructuring expenses paid of $16.0 million, $5.6 million, and $3.6 million for 2016, 2015 and 2014, respectively; repositioning expenses paid of $35.5 million and $38.6 million and cash paid for taxes related to repositioning of $5.0 million and $6.1 million for 2016 and 2015, respectively; cash paid for third-party acquisition-related costs of $2.3 million for 2016; and accelerated defined benefit pension plan contributions of $74.2 million for 2014. Included in capital expenditures are $2.0 million and $7.5 million related to repositioning for 2016 and 2015.

Employee Benefit Plans
See Note 8 to the Consolidated Financial Statements for further discussion of Pension Plans and Other Postretirement BenefitRetirement Plans.
Defined Contribution Retirement Plan
We sponsor a defined contribution retirement plan for our employees in the United States. This plan is qualified under section 401(k) of the U.S. tax code. Currently, we contribute an amount equal to 100% of employee contributions, up to 6% of an individual employee'semployee’s salary or wages. Our costs related to this benefit plan were $11.112.6 million, $10.411.5 million and $9.311.1 million for the years ended December 31, 20162018, 20152017 and 20142016, respectively.
Defined Benefit Pension Plans
We sponsor defined benefit pension plans for our employees in the U.S., Canada, Germany, and a number of other countries, and fund government-sponsored programs in other countries where we operate. Certain of our defined benefit pension plans are advance-funded and others are pay-as-you-go. The advance-funded plans are administered by trustees who directreceive direction related to the management of plan assets and arrange to have obligations paid when due. Our most significant advance-funded plans cover current and former salaried employees in the U.S. and employees covered by collective bargaining agreements at certain of our U.S. facilities. Our U.S. advance-funded plans are qualified under the U.S. tax code.

Underfunded plans include a group of advance-funded plans that are underfunded on a PBO basis by a total of $83.167.8 million as of December 31, 20162018. Additionally, we have several plans that are funded on a pay-as-you-go basis, and therefore, the entire PBO of $355.6380.0 million at December 31, 20162018, is unfunded. The combined balance of the underfunded and unfunded plans was $438.7447.8 million as of December 31, 20162018, and is presented as a liability on the Consolidated Balance Sheets as follows: $14.414.7 million in "other“other current liabilities,"liabilities” and $424.3433.1 million included in "underfunded“underfunded and unfunded defined benefit pension plans."
At the December 31, 20162018, measurement date for the U.S. advance-funded plans, the PBO was approximately $1,168930 million as measured under U.S. GAAP. The PBO is measured as the present value (using a 4.064.22% weighted average discount rate as of December 31, 20162018) of vested and non-vested benefits earned from employee service to date, based upon current services and estimated future pay increases for active employees. Of the participants in the U.S. advance-funded plans, approximately 8778% are retired or former employees or employees of our former businesses, which shortens the duration of the PBO. Assets available to fund the PBO for the U.S. advance-funded plans at December 31, 20162018, were approximately $1,086$871 million,, or approximately $82$59 million less than the measured obligation.

Tax Matters
We generated approximately $1,800 million in U.S. federal tax deductions relating to our emergence from bankruptcy. These deductions generated U.S. federal and state NOL carryforwards in 2014, which we will carry forward and expect to utilize in subsequent years. Under U.S. federal income tax law, a corporation is generally permitted to carry forward NOLs for a 20-year period for deduction against future taxable income. We generated additional U.S. federal tax deductions of $30 million upon payment of the ZAI PD deferred payment obligation on February 3, 2017. (See Note 10 to the Consolidated Financial Statements for Chapter 11 information.)

Table of Contents

We pay cash taxes in foreign jurisdictions and a limited number of states. In 2016, income taxes paid in cash, net of refunds, which includes payments related to the Separation, certain true-up payments made to foreign jurisdictions, and a prepayment of foreign taxes, were $85.2 million or approximately 51% of income before income taxes.
As of December 31, 2014, we had the intent and ability to indefinitely reinvest undistributed earnings of our foreign subsidiaries outside the United States. In 2015, in connection with the Separation, we repatriated a total of $173.1 million of foreign earnings from foreign subsidiaries transferred to GCP pursuant to the Separation. Such amount was determined based on an analysis of each non-U.S. subsidiary's requirements for working capital, debt repayment and strategic initiatives. We also considered local country legal and regulatory restrictions. We included tax expense of $19.0 million in discontinued operations in 2015 for repatriation and $1.3 million in the 2016 first quarter for deemed repatriation attributable to both current and prior years' earnings.
We believe that the Separation was a one-time, non-recurring event, and such recognition of deferred taxes on undistributed earnings would not have occurred if not for the Separation. Subsequent to the Separation, we expect undistributed prior-year earnings of our foreign subsidiaries to remain permanently reinvested except in certain instances where repatriation of such earnings would result in minimal or no tax. We base this assertion on:
(1)the expectation that we will satisfy our U.S. cash obligations in the foreseeable future without requiring the repatriation of prior-year foreign earnings;
(2)plans for significant and continued reinvestment of foreign earnings in organic and inorganic growth initiatives outside the U.S.; and
(3)remittance restrictions imposed by local governments.
We will continually analyze and evaluate our cash needs to determine the appropriateness of our indefinite reinvestment assertion.
See Note 7 to the Consolidated Financial Statements and "Income Taxes" above for additional discussion of our tax accounting matters including unrecognized tax benefits.
Other Contingencies
See Note 10 to the Consolidated Financial Statements for a discussion of our other contingent matters.
Inflation
We recognize that inflationary pressures may have an adverse effect on us through higher asset replacement costs and higher raw materials and other operating costs. We experienced raw materials cost inflation during the 2017 second half and throughout 2018 and expect to see continued inflation in 2019 but at a lower rate than in 2018. We try to minimize these impacts through effective control of operating expenses, and productivity improvements, and hedging purchases of certain raw materials, as well as price increases to customers.
We estimate that the cost of replacingon our property and equipment today is greater than its historical cost. Accordingly, our depreciation expense would be greater if the expense were stated on a current cost basis.products.
Critical Accounting Estimates
The preparation of financial statements in conformity with U.S. GAAP requires that we make estimates and assumptions affecting the assets and liabilities reported at the date of the Consolidated Financial Statements, and

Table of Contents

the revenues and expenses reported for the periods presented. We believe that our accounting estimates are appropriate and the related balances are reasonable; however, actual amounts could differ from the original estimates, requiring adjustments in future periods. Changes in estimates are recorded in the period in which the change is identified. Our accounting policies are described in Note 1 to the Consolidated Financial Statements. Critical accounting estimates are described in this section.
An accounting estimate is considered critical if the estimate requires management to make assumptions and judgments about matters that were highly uncertain at the time the estimate was made, if different estimates reasonably could have been used, or if changes in the estimate are reasonably likely to occur from period to period that could have a material impact on our financial condition or results of operations. As part of our quarterly disclosure controls and procedures, management has discussed the development, selection and disclosure of the critical accounting estimates with the Audit Committee of the Board of Directors.


Contingent Liabilities
We have recorded a liability for the resolution of contingencies related to asbestos property damage, environmental remediation, income taxes and litigation. We record a liability if we have determined that a loss is probable and we are able to reasonably estimate the amount of the loss or have another reasonable basis for recording a liability. We have determined that each of the contingencies discussed below involves an accounting judgment that is material to our Consolidated Financial Statements.
Asbestos Property Damage LawsuitsLegacy Product Liabilities
We were a defendant in property damage and personal injury lawsuits relating to previously sold asbestos-containing products. Asemerged from an asbestos-related Chapter 11 bankruptcy on February 3, 2014, as discussed in Note 10 to the Consolidated Financial Statements, we emerged from Chapter 11 on February 3, 2014.
Statements. Under the plan of reorganization, all pending and future asbestos-related claims are channeled for resolution to either the PI Trust or the PD Trust. The trusts are the sole recourse for holders of asbestos-related claims. The channeling injunctions issued by the bankruptcy court prohibit holders of asbestos-related claims from asserting such claims directly against us.
We have satisfied all of our financial obligations to the PI Trust. We have fixed and contingent financial obligations remaining to the PD Trust. With respect to property damage claims related to ZAI PD Claims, the PD Trust was funded with $34.4 million on the Effective Date and $30 million on February 3, 2017. The liability of $30.0 million was included in "debt payable within one year" in the Consolidated Financial Statements as of December 31, 2016. We are also obligated to make up to 10 contingent deferred payments of $8 million each per year to the PD Trust in respect of ZAI PD Claims during the 20 year20-year period beginning on the fifth anniversary of the Effective Date, with each such payment due only if the assets of the PD Trust in respect of ZAI PD Claims fall below $10 million during the preceding year. As of December 31, 2018, we have evaluated the activity in the PD Trust with respect to ZAI PD Claims and other trust expenses.
Through December 31, 2018, the PD Trust has paid approximately $15 million in ZAI PD Claims, approximately $6 million in operating and education expenses, and approximately $15 million in one-time attorneys’ fees. The PD Trust balance was approximately $30 million as of December 31, 2018. We expect ZAI PD Claims payments to decline over time but have limited information to estimate the amount and timing of future claims payments. It is reasonably possible that one or more contingent deferred payments will be made in the future. We estimate the present value of reasonably possible future payments to range between $0 million and $20 million. We have not accrued for the 10 additionalany contingent deferred payments as we do not currently believe they arethat payment is probable. We will continue to evaluate new information as it becomes available and will revise our estimate of the amount and timing of future claims payments and any contingent deferred payments at that time. We are not obligated to make additional payments to the PD Trust in respect of ZAI PD Claims beyond the payments described above. We have satisfied all of our financial obligations with respect to Canadian ZAI PD Claims.
With respect to Other PD Claims, claims unresolved as of the Effective Date are to be litigated in the bankruptcy court and any future claims are to be litigated in a federal district court, in each case pursuant to procedures approved by the bankruptcy court. To the extent any such Other PD Claims are determined to be allowed claims, they are to be paid in cash by the PD Trust. We are obligated to make a payment to the PD Trust every six months in the amount of any Other PD Claims allowed during the preceding six months plus interest (if applicable) and the amount of PD Trust expenses for the preceding six months. We have not paid any Other PD Claims since emergence. Annual expenses have been approximately $0.2 million per year. The aggregate amount to be paid under the PD Obligation is not capped, and we may be obligated to make additional payments to the PD Trust in respect of the PD Obligation. We have accrued for those unresolved Other PD Claims that we


believe are probable and estimable. We have not accrued for other unresolved or unasserted Other PD Claims as we do not believe that payment is probable.
All payments to the PD Trust required after the Effective Date are secured by our obligation to issue 77,372,257 shares of Company common stock to the PD Trust in the event of default, subject to customary anti-dilution provisions.
We generated approximately $1,800 million in U.S. federal tax deductions in 2014 relating to our emergence from bankruptcy, including approximately $670 million relating to payments made upon emergence, $632 million upon payment of the PI deferred payment obligation, and $490 million upon repurchase of the warrant held by the PI Trust. The deferred payment to the ZAI PD Account is expected to be deductible at the time of payment. See Note 7 to the Consolidated Financial Statements for a discussion of tax deductions generated in connection with emergence from Chapter 11.
Environmental Remediation
We are obligated under applicable law to remediate certain properties related to our business or former businesses. At some sites we outsource all or a portion of the remediation to third parties, and at others we perform the required remediation ourselves. Our environmental remediation obligation has a significant impact on our Consolidated Financial Statements. See disclosure in this Report in Item 1 (Business—Environment, Health


and Safety Matters) and in Note 10 to the Consolidated Financial Statements for a discussion of our environmental remediation liabilities.
At sites where third parties conduct remediation, we estimate our obligations from information available to us through such third parties, including actual costs incurred, expected future costs and time to completion. At sites where we conduct remediation, we use available information, work with regulatory authorities to define compliance requirements, and then estimate the cost required to meet those requirements. We base our estimates on our historical knowledge and engineering assessments specific to conditions at each site, and we update our estimates as necessary.
Our estimates can fluctuate significantly due to the extended duration of some remediation projects. The accuracy of our estimates is dependent on the validity of assumptions regarding regulatory approaches and such matters as labor rates, indirect costs and capital costs, which are each difficult to forecast over extended periods. It is not practicable to estimate the impact on our Consolidated Financial Statements of using other reasonably possible assumptions. Future changes in estimates, if required, will more than likelymay lead to material adjustments to our Consolidated Financial Statements, and we expect the ultimate resolution of these obligations tocould have a material impact on our liquidity and capital resources.
We purchased a vermiculite mine in Libby, Montana, in 1963 and operated it until 1990. Vermiculite concentrate from the Libby mine was used in the manufacture of attic insulation and other products. Some of the vermiculite ore that was mined at the Libby mine contained naturally occurring asbestos. We are engaged with the EPA and other federal, state and local governmental agencies in a remedial investigation and feasibility study of the Libby mine and the surrounding area.area, known as OU3. The RI/FS will determine the specific areas within OU3 requiring remediation and will identify possible remedial action alternatives. Possible remedial actions within OU3 are wide-ranging, from institutional controls such as land use restrictions, to more active measures involving soil removal, containment projects, or other protective measures.
As part of the RI/FS process, we contracted an engineering and consulting firm to develop a range of possible remedial alternatives and associated cost estimates for OU3. Based on this work, we recorded a pre-tax charge of $70.0 million in the 2018 third quarter for the estimated costs of remediation of OU3. We do not have sufficient informationbelieve that this amount should provide for a protective remedy meeting the statutory requirements of the Comprehensive Environmental Response, Compensation, and Liability Act.
The estimated costs of remediation are preliminary and consist of several components, each of which may vary significantly as the remedial alternatives are further developed. It is reasonably possible that the ultimate costs of remediation could range between $30 million and $170 million. Grace is working closely with the EPA, and the ultimate remedy will be determined by the EPA after the RI/FS is finalized. Such remedy will be set forth in a Record of Decision (“ROD”) that is expected to estimatebe issued by the EPA during or after 2020. Costs associated with the more active remedial alternatives would be expected to be incurred over a decade or more. We will reevaluate our estimated liability as remedial alternatives evolve based on further work by the engineering and consulting firm and discussions with the EPA as the RI/FS process moves toward a ROD. Depending on the remedial alternatives that the EPA selects in the ROD, the total cost of any required remediation of the Libby mine or surrounding area. remediating OU3 may exceed our current estimate by material amounts.
The EPA is also investigating or remediating formerly owned or operated sites wherethat processed Libby vermiculite concentrate from the Libby mine may have been used, stored or processed.into finished products. We are cooperating with the EPA on these investigationsinvestigation and remediation activities and have remediated, or paid for remediation, at several of these facilities. We have specific reserves for each site where an assessmentrecorded a liability to the extent that our review has indicated that a probable liability has been


incurred and the cost can be reasonably estimated.is estimable. These liabilities cover the estimated cost of investigations and, to the extent an assessment has indicated that remediation is necessary, the estimable cost of response actions. Response actions typically involve soil excavation and removal, and replacement with clean fill. The EPA may requestcommence additional remediation at other facilities. A liability will be recordedinvestigations in the future should Grace determineat other sites that an obligationprocessed Libby vermiculite, but we do not believe, based on our knowledge of prior and current operations and site conditions, that liability for remediation at such other sites is probable and reasonably estimable.probable.
Our current estimates of our environmental remediation obligations do not include the cost to remediate the Libby vermiculite mine and surrounding area or costs related to any additional EPA claims, whether resulting from the EPA's investigation of former vermiculite processing sites or otherwise, which may be material but are not currently estimable. It is probablepossible that our ultimate liability for environmental remediation will exceed our current estimates by material amounts.
Other Legacy Liabilities
As part of the process for renewing our permit for a dam on the Libby mine site, which expires in March 2019, the Montana Department of Natural Resources and Conservation is expected to require us to replace the dam spillway, which is deteriorating, with a new spillway. We constructed the dam in 1971 to prevent vermiculite ore tailings from moving into nearby creeks and rivers. Based on information provided by third-party consultants, the cost of the new spillway is estimated to be between $40 million and $45 million. We expect to record a liability for this project at the time the permit renewal is approved. We anticipate that approval of the renewal of such permit will occur in the first quarter of 2019. Construction of the new spillway is expected to take three to four years.
Litigation
We are subject to legal proceedings and claims arising out of the normal course of business. To estimate the cost to resolve our legal obligations, we review the facts of each matter to determine the merits of the case and the corresponding probability of a loss. If we determine that a loss is probable, we determine if there is sufficient information to make a reasonable estimate of the loss amount. Our estimates regarding the outcome of our legal proceedings and claims involve substantial uncertainties that could cause our actual losses to differ materially from our estimates. In estimating the likely outcome of a legal proceeding, we consider the nature of the specific claim (or unasserted claim), our experience with similar claims, the jurisdiction in which the proceeding is filed, court rulings, the status of any settlement negotiations, the likelihood of resolution through settlement or alternative dispute resolution, the proceeding'sproceeding’s current status and other relevant information and events. We adjust our recorded liability for litigation contingencies as necessary to reflect our current evaluation of these and other factors.
Goodwill and Intangible Assets
We account for business combinations under the acquisition method of accounting, which requires us to allocate the purchase price to the tangible and identifiable intangible assets and liabilities acquired based on their estimated fair values at the acquisition date in accordance with ASC 805 “Business Combinations.” The excess of the purchase price over the fair values of these identifiable assets and liabilities is recorded to goodwill. The assessment of fair value requires management to make significant estimates, including future expected revenues, earnings, and cash flows; expected useful lives; and attrition and discount rates. The allocation of the purchase price may be adjusted during the measurement period, which may not exceed one year after the acquisition date.
We review our finite-lived tangible and intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. We have no indefinite-lived intangible assets. There were no impairment charges recorded in any of the periods presented.
We review our goodwill for impairment on an annual basis at October 31 and whenever events or a change in circumstances indicate that the carrying amount may not be fully recoverable. We have identified our operating segments as reporting units for goodwill impairment testing. Our Catalysts Technologies reportable segment has two reporting units for goodwill impairment testing, which are theour Refining Technologies and Specialty Catalysts operating segments. Our Materials Technologies operating segment represents a single reporting unit for goodwill impairment testing.
We performed a quantitative analysis as of October 31, 2016,2018, and concluded that the estimated fair value of all of our reporting units substantially exceeded their carrying values.


Pension Expenses and Liabilities
We sponsor defined benefit pension plans for our employees in the United States and a number of other countries, including Canada and Germany, and fund government-sponsored programs in other countries where we operate. See Note 8 to the Consolidated Financial Statements for a detailed discussion of our pension plans and other postretirement benefit plans.
In order to estimate our pension expenses and liabilities we evaluate the range of possible assumptions to be used in the calculation of pension expenses and liabilities. We select the assumptions that we believe to be most indicative of factors such as participant demographics, past experiences and market indices, and provide the assumptions to independent actuaries. These assumptions are updated annually and primarily include factors such as discount rates, expected return on plan assets, mortality rates, retirement rates, and rate of compensation increase. The independent actuaries review our assumptions for reasonableness, and use the assumptions to calculate our estimated liability and future pension expense. We review the actuarial reports for reasonableness and adjust our expenses, assets and liabilities to reflect the amounts calculated in the actuarial reports.
The two key assumptions used in determining our pension benefit obligations and pension expense are the discount rate and expected return on plan assets. Our most significant pension assets and pension liabilities relate to U.S. pension plans.
The assumed discount rate for pension plans reflects the market rates for high-quality corporate bonds currently available and is subject to change based on changes in overall market interest rates. For the U.S. pension plans, the assumed weighted average discount rate was selected in consultation with our independent actuaries, based on a yield curve constructed from a portfolio of high quality bonds for which the timing and amount of cash outflows approximate the estimated payouts of the plan.
We selected the expected return on plan assets for the U.S. qualified pension plans for 20162018 in consultation with our independent actuaries, using an expected return model. The model determines the weighted average return for an investment portfolio based on the target asset allocation and expected future returns for each asset class, which were developed using a building block approach based on observable inflation, available interest rate information, current market characteristics, and historical results.
The following table reflects the sensitivity of 20172019 pre-tax expense (excluding the effects of the annual mark-to-market adjustment) and our year-end projected benefit obligation, or PBO, to a change in the discount rate and expected rate of return on plan assets assumptions for the U.S. pension plans:

Income Taxes
Our global reach results in a complexity ofeffective tax regulations, which require assessments of applicable tax lawrate is primarily determined based on our pre-tax income and judgments in estimating our ultimatethe statutory income tax liability. See Note 7 torates in the Consolidated Financial Statementsjurisdictions in which we operate. The effective tax rate also reflects the tax impacts of items treated differently for additional details regardingtax purposes than for financial reporting purposes. Some of these differences are permanent, such as expenses that are not deductible in our estimates used in accounting fortax returns, and some differences are temporary, reversing over time, such as depreciation expense. These temporary differences create deferred income tax matters including unrecognizedassets and liabilities. Deferred income tax benefits.assets are also recorded for NOL and federal tax credit carryforwards.
Deferred income tax assets and liabilities are recognized by applying enacted tax rates to temporary differences that exist as of the balance sheet date. We recognizereduce the carrying amounts of deferred tax benefit from an uncertain tax position onlyassets by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the tax position will be sustained upon examination byrequirement for, and amount of, a valuation allowance in accordance with the taxing authorities, based on the technical merits of the position. We measure tax benefits in our financial statements from such a position as the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. Unrecognized tax benefits are tax benefits claimed in our tax returns that do not meet these recognition and measurement standards.
We record a liability for unrecognized tax benefits when it is more likely than not that a tax positionstandard, we have taken will not be sustained upon audit. We evaluate such likelihood based on relevant factsgive appropriate consideration to all positive and tax law. Wenegative evidence related to the realization of the deferred

adjust our recorded liability for income tax assets. This assessment considers, among other matters, due to changes in circumstances or new uncertainties, such as amendments to existing tax law. Our ultimate tax liability depends upon many factors, including negotiations with taxing authorities in the jurisdictions in which we operate, outcomesnature, frequency and severity of tax litigation,current and resolutioncumulative losses, forecasts of disputes arising from federal, state,future profitability and foreign source income (“FSI”), the duration of statutory carryforward periods, and our experience with operating loss and tax audits. Duecredit carryforward expirations. A history of cumulative losses is a significant piece of negative evidence used in our assessment. If a history of cumulative losses is incurred for a tax jurisdiction, forecasts of future profitability are not used as positive evidence related to the varying tax laws in each jurisdiction, management, withrealization of the assistance of local tax advisors as necessary, assesses individual matters in each jurisdiction on a case-by-case basis. We research and evaluate our income tax positions, including why we believe they are compliant with income tax regulations, and these positions are documented as appropriate.
Deferred income taxes result from the differences between the financial and tax basis of our assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. If it is more likely than not that all or a portion of deferred tax assets will not be realized, a valuation allowance is provided for such deferred tax assets. in the assessment.
As further described in Note 7 to the Consolidated Financial Statements, our Consolidated Balance Sheet as of December 31, 2016, we have recorded a valuation allowance2018, includes net deferred income tax assets of $31.4$518.5 million. Included in this amount are deferred U.S. federal income tax assets representing federal tax credit carryforwards of $291.0 million, on netfederal NOL carryforwards of $44.3 million, state NOL deferred income tax assets of $52.9 million, and foreign NOL deferred tax assets of $738.0$5.7 million. We have established valuation allowances in the amount of $19.9 million, consisting of which $17.7$6.6 million is related to U.S. federal credits, $11.2for state NOL carryforwards, $4.2 million to U.S. state NOLs, and $2.5 million tofor foreign NOLs. The balance of net deferred tax assets, netprimarily foreign operating loss carryforwards, and 5.2 million for federal tax credits.
In order to fully utilize our U.S. federal tax credits before they expire from 2021 to 2028, we will need to generate income of valuation allowance, is $706.6 million.
The following table summarizesapproximately $1.4 billion. We estimate that we will need to generate future U.S. taxable income of approximately $232 million before 2035 to fully utilize the balance of deferred tax assets, net of deferred tax liabilities, at December 31, 2016, of $706.6 million:

We will need to generate approximately $1,800 million of U.S. federal taxable$1.9 billion for state income by 2035 (or approximately $95 million per yeartax purposes during the carryforward period)respective realization periods (ranging from 2018 to 2035) in order to fully realize the U.S.state NOLs.
Inherent in determining our effective tax rate are judgments regarding business plans and expectations about future operations. These judgments include the amount and geographic mix of future taxable income, the amount of FSI, limitations on the usage of NOL carryforwards, the impact of ongoing or potential tax audits, and other future tax consequences.
The federal tax credit carryforwards arose primarily as a result of the payment of intercompany dividends from our foreign affiliates, from the mandatory repatriation under the TCJA, and from research and development credits. The federal and state NOLs arose primarily as a majorityresult of the U.S. state netamounts paid as a result of our bankruptcy proceedings.
Our ability to utilize deferred tax assets may be impacted by certain future events, such as changes in tax legislation or insufficient future taxable income or FSI prior to expiration of certain deferred tax assets.
The following table summarizes expiration dates in jurisdictions where we have, or will have, material tax loss carryforwards:
Expiration Dates
United States—Federal (NOLs)2033 - 2035
United States—Federal (Credits)2019 - 2026
United States—States (NOLs)2017 - 2035
In evaluating our ability to realize our deferred tax assets, we consider all reasonably available positive and negative evidence, including recent earnings experience, expectations of future taxable income andWe recognize the tax characterbenefits of that income, the extended period of time over which the temporary differences become deductible and the carryforward and/or carryback periods available to us foran uncertain tax reporting purposes in the related jurisdiction. In estimating future taxable income, we develop assumptions, including the amount of future federal, state and international pretax operating income that we can reasonably expect to generate, the reversal of temporary differences and the implementation of feasible and prudent tax planning strategies. We record a valuation allowance to reduce deferred tax assets to the amount that we believe isposition if those benefits are more likely than not to be realized.
U.S. federal deferredsustained based on existing tax assets associated with certain credit carryforwards have expiration dates through 2021 andlaw. Additionally, we establish a reserve for tax positions that are projected to expire before they can be utilized. We have recorded a valuation allowance of $17.7 million on these credits. We concluded that a valuation allowance is not required with respect to the remaining U.S. federal deferred tax assets of $622.7 million because we believe we will have sufficient U.S. taxable income to realize all future available tax deductions and remaining credits prior to their expiration.

Table of Contents

We also considered the need for a valuation allowance on state deferred tax assets. We have considered forecasted earnings, recent past and future taxable income and allowable carryforward periods of net operating losses in each state taxing jurisdiction in which we operate. We believe that we will generate sufficient domestic income in most state and local jurisdictions to utilize future deductions.
There are certain states where a portion of the NOLs generated in prior years will not be utilized prior to their expiration and for which, as of December 31, 2016, a valuation allowance in the aggregate of $11.2 million remains in place.
The realization of deferred tax assets is dependent on the generation of sufficient taxable income in the appropriate tax jurisdictions. We believe it is more likely than not that the net deferredto be sustained based on existing tax assets as of December 31, 2016, will be realized. If we were to determine that we would not be able to realize a portion of our net deferred tax assetslaw, but uncertain in the future, for which there is currently no valuation allowance, an adjustmentultimate benefit to be sustained upon examination by the net deferredrelevant taxing authorities. Unrecognized tax assets would be charged to earnings inbenefits are subsequently recognized at the period such determination was made.

(1)Effects of currency translation and, in 2016, the Separation.
(2)The valuation allowance increased $7.9 million from December 31, 2017, to December 31, 2018. The increase was primarily due to expected foreign tax credit utilization.
(3)The increase was primarily related to a pre-tax charge of $70.0 million for the estimated costs of future remediation-related activities at the former vermiculite mine site in Libby, Montana.
(4)The allowance for accounts receivable increased primarily due to a $10.0 million charge to fully reserve for a trade receivable from a Venezuela-based customer related to increased economic uncertainty and the recent political unrest and sanctions.
(5)The valuation allowance decreased $19.4 million from December 31, 2016, to December 31, 2017. The decrease was primarily due to the effects of U.S. tax reform.
(6)The valuation allowance increased $23.0 million from December 31, 2015, to December 31, 2016. The increase was primarily due to the adoption of ASU 2016-062016-09 as well as the ability to utilize NOL carryforwards as a result of the Separation.
(3)The valuation allowance decreased $2.3 million from December 31, 2014, to December 31, 2015. The decrease was primarily due to a reduction in the valuation allowance on state NOL carryforwards.
(4)The valuation allowance decreased $6.0 million from December 31, 2013, to December 31, 2014. The decrease was primarily due to a reduction in the valuation allowance on state NOL carryforwards, partially offset by an increase in the valuation allowance on NOLs in certain foreign jurisdictions.
