Our team’s deep commitment to operational excellence and continuous improvement activities along with pricing actions mitigated the impact of inflationary costs during the year.

Operating income, excluding special items, was $51.1 million and represented 14.6 percent of sales.

Performance Materials segment sales increased 6 percent to $206.8 million. Metalcasting sales rose 6 percent, primarily driven by higher volumes of greensand bonds in North America and Asia.  Household, Personal Care & Specialty Products sales increased 50 percent due to the acquisition of Sivomatic and the continued strong growth of our pet care products in North America and China. This growth was partially offset by lower sales in Building Materials resulting from fewer large projects and a decrease in Basic Minerals due to the exit of the bulk chromite business last year. Operating income for the segment increased 4 percent to $29.2 million due to higher pricing, volume and operating efficiencies, partially offset by increased raw material, logistics and energy costs.The Performance Materials segment provides a wide range of bentonite-based and synthetic materials for industrial and consumer markets and for non-residential construction, environmental remediation and infrastructure projects worldwide.

Specialty Minerals segment sales, which consist of the Precipitated Calcium Carbonate (PCC) and Processed Minerals product lines, decreased 1 percent to $142.5 million. Operating income, excluding special items, decreased to $21.9 million, driven by previously announced customer paper machine shutdowns in North Americain late 2017 and early 2018, and higher logistics and energy costs.Contractual selling price increases in PCC and other price increases were implemented in the second half of 2018 and will continue into 2019 to partially offset rising costs.

Worldwide sales of PCC, which is used mainly in the manufacturing processes of the paper industry, decreased 1 percent to $109.6 million, primarily due toreduced sales in North America following the paper machine closures.

Sales of Processed Minerals products were flat at $32.9 million. Processed Minerals products are used in the building materials, polymers, ceramics, consumer products, paints and coatings, glass and other manufacturing industries.

	Included in marketing and administrative expenses in the fourth quarter of 2017 is a provision for bad debt of $2.1 million related to a bankruptcy of a Paper PCC customer in Malaysia.
4)	On December 22, 2017, tax reform legislation was signed into law, encompassing a broad range of tax reform proposals, including a reduction of U.S. corporate tax rates from 35% to 21%, transitioning U.S. international taxation from a worldwide tax system to a territorial tax system and imposing a repatriation tax that is payable over eight years on deemed repatriated accumulated earnings of foreign subsidiaries.  As required under ASC 740, Income Taxes, the Company is required to recognize the effects of changes in tax laws and rates on deferred tax positions and the retroactive effects of changes in tax laws in the period in which the new legislation is enacted.  As such, the Company recorded a provisional $47 million income tax benefit in the fourth quarter of 2017, comprised of a tax benefit primarily from the lower U.S. tax rate, resulting in a reduction of deferred tax liabilities of $82 million and a $35 million charge related to the repatriation of accumulated foreign earnings. Such provisional amounts were based on reasonable estimates and subject to to adjustment during the measurement period.  Accordingly, in the fourth quarter of 2018, the Company recorded a $3.7 million reduction related to the repatriation of accumulated foreign earnings.
5)	Free cash flow is defined as cash flow from continuing operations less capital expenditures.  The following is a presentation of the Company's non-GAAP free cash flow for the quarterly periods ended December 31, 2018, September 30, 2018  and December 31, 2017 and the years ended December 31, 2018 and 2017 and a reconciliation to cash flow from operations for such periods.  The Company's management believes this non-GAAP measure provides meaningful supplemental information as management uses this measure to evaluate the Company's ability to maintain capital assets, satisfy current and future obligations, repurchase stock, pay dividends and fund future business opportunities.  Free cash flow is not a measure of cash available for discretionary expenditures since the Company has certain non-discretionary obligations such as debt service that are not deducted from the measure.  The Company's definition of free cash flow may not be comparable to similarly titled measures reported by other companies.

To supplement the Company's consolidated financial statements presented in accordance with GAAP, the following is a presentation of the Company's non-GAAP operating income, excluding special items (set forth in the above table), for the quarterly periods ended December 31, 2018, September 30, 2018, and December 31, 2017, and the twelve month periods ended December 31, 2018 and December 31, 2017 constituting a reconciliation to GAAP operating income set forth above.  The Company's management believe these non-GAAP measures provide meaningful supplemental information regarding its performance as inclusion of such special items are not indicative of ongoing operating results and thereby affect the comparability of results between periods.  The Company feels inclusion of these non-GAAP measures also provides consistency in its financial reporting and facilitates investors' understanding of historic operating trends.
