The Company also owns a 33% interest in AMAK,Al Masane Al Kobra Mining Company ("AMAK"), a Saudi Arabian closed joint stock mining company, which is engaged in the commercial production of copper and zinc concentrates and silver and gold doré.  Finally,
On October 2, 2019, we announced that we had entered into a Share Sale and Purchase Agreement (as amended, the “Purchase Agreement”) pursuant to which we have agreed to sell our entire investment in AMAK. On January 16, 2020, the Purchase Agreement was amended to allow additional time for the parties to obtain certain required governmental approvals. The Amendment also provides that, if closing does not occur on or before March 31, 2020, and the Company determines in its sole discretion to further extend such date, then an amount equal to 50% of the approximately $3.5 million non-refundable deposit will be forfeited to the Company as liquidated damages and shall not be applied to the purchase price at closing. AMAK's historical financial results for the periods presented are reflected in our consolidated financial statements as discontinued operations. For further details, refer to Note 6 to the Consolidated Financial Statements.
The Company also has a 55% interest in PEVM,Pioche Ely Valley Mines, Inc. ("PEVM"), a Nevada mining corporation, which presently does not conduct any substantial business activity but owns undeveloped properties in the United States.

In November 2019, PEVM entered into a sales contract which, upon completion of due diligence, may lead to liquidation of substantially all of its remaining assets. Upon closing of the sale, PEVM will be dissolved. Any proceeds from the sale will primarily be used to repay outstanding indebtedness of PEVM owed to the Company.
Business Segments

We operate in two business segments; the manufacturing of various specialty petrochemicalpetrochemicals products and the manufacturing of specialty synthetic waxes.

Our specialty petrochemicalpetrochemicals products segment is conducted through SHR, a Texas corporation. SHR owns and operates a specialty petrochemicalpetrochemicals facility nearin Silsbee, Texas which produces high purity hydrocarbons and other petroleum based products including isopentane, normal pentane, isohexane and hexane. These products are used in the production of polyethylene, packaging, polypropylene, expandable polystyrene, poly-iso/urethane foams, crude oil from the Canadian tar sands, and in the catalyst support industry.   Our petrochemicalspecialty petrochemicals products are typically transported to customers by rail car, tank truck, iso-container, and by ship. SHR owns all of the capital stock of GSPL, a Texas corporation, which owns and operates pipelines that connect the SHR facility to a natural gas line, to SHR's truck and rail loading terminal and to a major petroleum products pipeline owned by an unaffiliated third party. SHR also provides custom processing services.

services at its Silsbee facility.
Our specialty synthetic waxwaxes segment is conducted through TC, a Texas corporation, located in Pasadena, Texas which produces specialty polyethylene and poly alpha olefin waxes and provides custom processing services. The specialty polyethylene waxes are used in markets from paints and inks to adhesives, coatings, and PVC lubricants. The highly specialized synthetic poly alpha olefin waxes are used in applications such as toner in printers and as additives for candles providing rigidity and retention of fragrances.candles. These waxes are sold in solid form as pastilles or, for large adhesive companies, in bulk liquid form.

See Note 1817 to the Consolidated Financial Statements for more information.

United States Specialty PetrochemicalPetrochemicals Operations

SHR's specialty petrochemicalpetrochemicals facility is located in Silsbee, Texas approximately 30 miles north of Beaumont and 90 miles east of Houston. The base SHR facility consists of eightfive operating units which, while interconnected, make distinct products through differing processes: (i) a Penhex Unit; (ii) a Reformer Unit; (iii) a Cyclo-pentane Unit; (iv) an Aromax® Unit;Advanced Reformer unit; and (v) an Aromatics Hydrogenation Unit; (vi) a White Oil Fractionation Unit; (vii) a Hydrocarbon Processing Demonstration Unit and (viii) a P-XyleneIsomerization Unit. All of these units are currently in operation.

In addition to the base plant, SHR operates three proprietary chemical production facilities for toll processing customers. The Penhex Unit currently has the permitted capacity to process approximately 11,00011,000 barrels per day of fresh feed with thefeed. The Reformer Unit, the Aromax® Unit,Advanced Reformer unit, and the Cyclo-Pentane Unit further processingprocess streams produced by the Penhex Unit.  The Aromatics Hydrogenation Unit has a capacity of approximately 400 barrels per day, and the White Oils Fractionation Unit has a capacity of approximately 3,000 barrels per day.  The Hydrocarbon Processing Demonstration Unit has a capacity of approximately 300 gallons per day.  The P-Xylene Unit has a capacity of approximately 20,000 pounds per year. 
The facility generally consists of equipment commonly found in most petrochemical facilities such as fractionation towers and hydrogen treaters, except the facility is adapted to produce specialized products that are high purity and very consistent with precise specifications that are utilized in the petrochemical industry as solvents, additives, blowing agents and cooling agents.  We produce eight distinct product streams and market several combinations of blends as needed in various customer applications.  We do not produce motor fuel products or any other commodity type products commonly sold directly to retail consumers or outlets.
DuringIn 2015, we constructed and started up D Train, a new Penhex production unit which is part of the Penhex Unit, D Train, which began production in the fourth quarter of 2015.at our Silsbee facility. The D Train expansion increased our capacity by approximately 6,000 barrels per day of fresh feed. Our present total capacity is 13,000 barrels per day of fresh feed; however, we are currently only permitted to process 11,000 barrels per day. Products from the Penhex Unit, Reformer Unit, Aromax® Unit, and Cyclo-pentane Unit are marketed directly to the customer by our marketing personnel.  The Penhex Unit hadDuring 2018, we constructed a utilization rate during 2017 of approximately 53% based upon 11,0004,000 barrels per day Advanced Reformer unit to increase our capability to upgrade by-products produced from the PenHex Unit and to provide security of capacity. The Penhex Unit had a utilization rate during 2016hydrogen supply to the plant. We believe we have sufficient pentane capacity to maintain our share of approximately 48% based upon 11,000 barrels per day of capacity.  The Penhex Unit had a utilization rate during 2015 of approximately 84% based upon 7,000 barrels per day.  Penhex Unit capacity is now configured in three independent process units.  The three unit configuration improves reliability by reducingmarket growth for the amount of total down time due to mechanical and other factors.  This configuration also allows us to use spare capacity for new product development.

foreseeable future.
The Advanced Reformer, Reformer and Aromax® UnitsIsomerization units are operated as needed to support the Penhex and Cyclo-pentane Units. Consequently, utilization rates of these units are driven by production from the Penhex Unit.
Operating utilization rates are affected by product demand, raw material composition, mechanical integrity, and unforeseen natural occurrences, such as weather events. The nature of the petrochemical process demands periodic shut-downs for de-cokingdecoking and other mechanical repairs.  A new 4000 barrel per day Aromax® unit is under construction and is expected to start-up in third quarter 2018.  This unit will provide security of hydrogen supply for Penhex and custom processing projects as well as, increasing value of our by-products.  On February 14, 2018, while commissioning the new Aromax® unit, it overheated and ignited a small fire. The response team quickly extinguished the fire without injury, and there was no environmental impact.  Despite the quick reaction of the team, there was some damage to all six heaters in the unit, and the damaged equipment will have to be replaced.  Insurance adjustors have been to the site, and while it is too early to have a firm estimate of repair costs, it is anticipated that the Company's insurers will cover any costs over the $1 million deductible.
The Company remains optimistic about the business benefits of the new Aromax® unit, which we believe will convert byproducts of pentane production into a significantly higher value byproduct stream through proven technology.

The Aromatics Hydrogenation Unit, White Oils Fractionation Unit, Hydrocarbon Processing Demonstration Unit and P-Xylene Unit are operated as independent and completely segregated processes.  These units are dedicated to the needs of three different toll processing customers.  The customers supply and maintain title to the feedstock, we process the feedstock into products based upon customer specifications, and the customers market the products.  Products may be sold directly from our storage tanks or transported to the customers' location for storage and marketing.  The units have a combined capacity of approximately 3,400 barrels per day. Together they realized a utilization rate of 21% for 2017, 26% for 2016, and 27% for 2015.  The units are operated in accordance with customer needs, and the contracts call for take or pay minimums of production.

In support of the petrochemicalspecialty petrochemicals operation, we own approximately 100 storage tanks with total capacity approaching 285,000 barrels, and 127 acres of land at the plant site, 92 acres of which are developed. We also own a truck and railroad loading terminal consisting of storage tanks, fournine rail spurs, and truck and tank car loading facilities on approximately 63 acres of which 33 acres are developed.

We obtain substantially all our feedstock requirements from a sole supplier. The agreement is primarily a logistics convenience.  Thearrangement whereby the supplier buys or contracts for feedstock material and utilizes their tank and pipeline connections to transport into our pipeline.  The supplier's revenue above feed cost is primarily related to the cost and operation of the tank, pipelines, and equipment. A contract was signed in August 2015 with a seven year term with subsequent one year renewals unless cancelledcanceled by either party with 180 days' notice.  In 2015, a pipeline connection to the supplier's dock was added to give alternative means of receiving feedstock.  Prior to this addition, all feedstock came from Mont Belvieu, Texas.

As a result of various expansion programs and the toll processing contracts, essentially all of the standing equipment at SHR is operational. We have various surplus equipment stored on-site which may be used in the future to assemble additional processing units as needs arise.

GSPL owns and operates three (3)two 8-inch diameter pipelines and five (5) 4-inch diameter pipelines, aggregating approximately 70 miles in length connecting SHR's facility to:to (1) a natural gas line, (2) SHR's truck and rail loading terminal and (3) a major petroleum products pipeline system owned by an unaffiliated third party. All pipelines are operated within Texas Railroad Commission and DOT regulations for maintenance and integrity.
We sell our products predominantly to large domestic and international companies. Products are marketed via personal contact and through continued long term relationships. Sales personnel visit customer facilities regularly and also attend various petrochemical conferences throughout the world. We also have a website withprovide information about our products and services.services through our website. We utilize eitherboth formula and non-formula based or spot pricing depending upon a customer's requirements.requirements and competitive situtations. Under formula pricing the price charged to the customer is primarily based on a formula which includes as a component the average cost of feedstock over the prior month. With this pricing mechanism, product prices move in conjunction with feedstock prices without the necessity of announced price changes.prices. However, because the formulas use an average feedstock price from the prior month, the movement of prices will trail the movement of costs, and formula prices may or may not reflect our actual feedstock cost for the month during which the product is actually sold. In addition, while formula pricing can reduce product margins during periods of increasing feedstock costs, during periods of decreasing feedstock costs formula pricing will follow feed costs down but will retain higher margins during the period by trailing the movement of costs by approximately 30 days. During 2017See additional discussion of concentration of revenue and 2016, salescorresponding receivables as disclosed in Note 3 to one customer exceeded 10% of our consolidated revenues.  Specifically, in 2017 sales to ExxonMobil and their affiliates represented 19.6% of revenues.  In 2016 sales to ExxonMobil and their affiliates represented 20.1% of revenues.  These sales represented multiple products sold to multiple facilities.the Consolidated Financial Statements.

Matters pertaining to the environment are discussed in Part I, Item 1A. Risk Factors;Factors, Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations;Operations and Notes 2 and 1514 to the Consolidated Financial Statements.

In 1993 during remediation of a small spill area, the Texas Commission on Environmental Quality (TCEQ)("TCEQ") required SHR to drill a well to check for groundwater contamination under the spill area. Two pools of hydrocarbons were discovered to be floating on the groundwater at a depth of approximately 25 feet. One pool is under the site of a former gas processing plant owned and operated by Sinclair, Arco and others before its purchase by SHR in 1981. Analysis of the material indicates it entered the ground prior to SHR's acquisition of the property. The other pool is under the original SHR facility and analysis indicates the material was deposited decades ago. Tests conducted have determined that the hydrocarbons are contained on the property and not migrating in any direction. The recovery process was initiated in June 1998 and approximately $53,000 was spent setting up the system. The recovery is proceeding as planned and is expected to continue for many years until the pools are reduced to acceptable levels. Expenses of recovery and periodic migration testing are being recorded as normal operating expenses. Expenses for future recovery are expected to stabilize and be less per annum than the initial set up cost, although there is no assurance of this effect.this. The light hydrocarbon recovered from the former gas plant site is compatible with our normal Penhex feedstock and is accumulated and transferred into the Penhex feedstock tank. The material recovered from under the original SHR site is accumulated and sold as a by-product. Approximately 80, 70,78, 144, and 7080 barrels were recovered during 2017, 20162019, 2018, and 2015,2017, respectively. The recovered material had an economica value of approximately $4,100, $5,800, and $4,200 $3,200,during 2019, 2018, and $3,500 during 2017, 2016, and 2015, respectively. Consulting engineers estimate that as much as 20,000 barrels of recoverable material may be available to us for use in our process or for sale.  At current market values this material, if fully recovered would be worth approximately $1.0 million. The final volume present and the ability to recover it are both highly speculative issues due to the area over which it is spread and the fragmented nature of the pockets of hydrocarbon. We have drilled additional wells periodically to further delineate the boundaries of the pools and to ensure that migration has not taken place. These tests confirmed that no migration of the hydrocarbon pools has occurred. The TCEQ has deemed the current action plan acceptable and reviews the plan on a semi-annual basis.

Personnel

The number of our regular, U.S. based employees was approximately270, 280, and 324 310, and 296 for the years ended December 31, 2017, 2016,2019, 2018, and 2015,2017, respectively. Of these employees, none are covered by collective bargaining agreements. Regular employees are defined as active executive, management, professional, technical and wage employees who work full time or part time for the Company and are covered by our benefit plans and programs. Our workforce has increaseddecreased primarily due to expansionscompletion of capital projects at both facilities.our facilities including a workforce downsizing at SHR in December 2018.

Competition

The petrochemical, specialty wax,petrochemicals, specialty waxes, and mining industries are highly competitive. There is competition within the industries and also with other industries in supplying the chemical and mineral needs of both industrial and individual consumers. We compete with other firms in the sale or purchase of needed goods and services and employ all methods of competition which are lawful and appropriate for such purposes. See further discussion under "Intense competition" in Part I, Item 1A.

Risk Factors.
Investment in AMAK

As of December 31, 2017,2019, we owned a 33.4%33% interest in AMAK.

Location, Access and Transportation.

The facility site is located in Najran province in southwestern Saudi Arabia. Najran, the capital of the province of the same name, is approximately 700 km southeast of Jeddah. The site is located 145 km northwest of Najran, midway between the outpost of Rihab and the district town of Sufah. A modern, paved highway extends from Najran through the town of Habuna passing by the project site and on to Sufah. Another modern, paved highway extends west from the town of Tirima aboutapproximately 30 km to the Asir provincial line, becomes a four-lane divided highway, and intersects with a highway leading to Khamis Mushait and Abha. A joining highway then extends down the western slope of the Sarawat
mountains to the coastal highway which follows the coast south to the Port of Jazan. The latter is the route AMAK's trucks carry concentrate to the port for export.

Conditions to Retain Title.

The Saudi government granted the Company a mining lease for the Al Masane area comprising approximately 44 square kilometers or approximately 10,870 acres on May 22, 1993 (the "Lease") under Royal Decree No. M/17. The Lease was assigned to AMAK in December 2008. The initial term of the Lease is thirty years beginning May 22, 1993, with AMAK having the option to renew or extend the term of the Lease for additional periods not to exceed twenty years. Under the Lease, AMAK is obligated to pay advance surface rental in the amount of 10,000 Saudi riyals (approximately $2,667 at the current exchange rate) per square kilometer per year (approximately $117,300 annually) during the term of the Lease. In addition, AMAK must pay income tax in accordance with the laws of Saudi Arabia and pay all infrastructure costs. The Lease gives the Saudi Arabian government priority to purchase any gold production from the project, as well as the right to purchase up to 10% of the annual production of other minerals on the same terms and conditions then available to other similar buyers and at current prices then prevailing in the free market. Furthermore, the Lease contains provisions requiring that preferences be given to Saudi Arabian suppliers and contractors and that AMAK employ Saudi Arabian citizens and provide training to Saudi Arabian personnel. In November 2015 AMAK received notification of final approval for additional licenses and leases. The approval includes an additional 151 square kilometers (km("km22") of territory contiguous to AMAK's current 44 km2 mine. The new territory comprises the Guyan and Qatan exploration licenses covering 151 km2, and within the Guyan exploration license, a 10 km2 mining lease, which has potential for significant gold recovery. Under the new leases, AMAK is required to pay surface rental of SR 110,000 (approximately $29,333) for a period of 20 years expiring in 2035.

Rock Formations and Mineralization.

Three mineralized zones, the Saadah, Al Houra and Moyeath, have been outlined by diamond drilling. The Saadah and Al Houra zones occur in a volcanic sequence that consists of two mafic-felsic sequences with interbedded exhalative cherts and metasedimentary rocks. The Moyeath zone was discovered after the completion of underground development in 1980. It is located along an angular unconformity with underlying felsic volcanics and shales. The principle sulphide minerals in all of the zones are pyrite, sphalerite, and chalcopyrite. The precious metals occur chiefly in tetrahedrite and as tellurides and electrum.

Description of Current Property Condition.

The AMAK facility includes an underground mine, ore-treatment plant and related infrastructures. The ore-treatment plant is comprised of primary crushing, ore storage, SAG milling and pebble crushing, secondary ball milling, pre-flotation, copper and zinc flotation, concentrate thickening, tailings filtration, cyanide leaching, reagent handling, tailings dam and utilities. Related infrastructure includes a 300 man capacity camp for single status accommodation for expatriates and Saudi Arabian employees, an on-site medical facility, a service building for 300 employees, on-site diesel generation of 15 megawatts, potable water supply primarily from an underground aquifer, sewage treatment plant and an assay laboratory. The facilities at the Port of Jazan are comprised of unloading facilities, concentrate storage and reclamation and ship loading facilities. The above-ground ore processing facility became fully operational during the second half of 2012. Late in the fourth quarter of 2015, AMAK temporarily closed the operation to preserve the assets in the ground while initiating steps to improve efficiencies and optimize operations. The plant resumed operation in the fourth quarter of 2016 and operating rates, metal recoveries and concentrate quality improved throughout 2017.

has continued to improve since.
AMAK shipped approximately 28,000, 16,000,65,000, 58,000, and 51,00028,000 metric tons of copper and zinc concentrate to outside smelters during 2017, 2016,2019, 2018, and 2015,2017, respectively. In 2014 AMAK initiated operation of its precious metal recovery circuit at the mill

and produced gold and silver doré intermittently through 2014 and 2015. The precious metals circuit was recommissioned in the fourth quarter of 2017 and is expected to productproduced commercial quantities of gold and silver bearing doré in 2018.

Saudi Industrial Development Fund ("SIDF") Loan and Guarantee

On October 24, 2010, we executed a limited guarantee in favor of the SIDF guaranteeing up to 41% of the SIDF loan to AMAK in the principal amount of 330,000,000 Saudi Riyals (US$88,000,000) (the "Loan"). As a condition of the Loan, SIDF required all shareholders of AMAK to execute personal or corporate guarantees totaling 162.55% of the overall Loan amount. As ownership percentages have changed over time, the loan guarantee allocation has
not changed. The other AMAK shareholders provided personal guarantees. We were the only AMAK shareholder providing a corporate guarantee. The loan was required in order for AMAK to fund construction of the underground and above-ground portions of its mining project in southwest Saudi Arabia and to provide working capital for commencement of operations. See Note 1514 to the Consolidated Financial Statements.

ItemITEM 1A.   Risk Factors.

Our financial and operating resultsWe are subject to a variety of risks inherent in the global petrochemical, specialty waxpetrochemicals, specialty waxes and mining businesses (due to our investment in AMAK). businesses. Many of these risk factors are not within our control and could adversely affect our business, our financial and operating results of operations or our financial condition.
Consummation of the sale of the Company's equity interest in AMAK is subject to a number of closing conditions, including receipt of certain governmental approvals, that may not be satisfied, and the closing of the sale may be delayed or the sale may not be completed as contemplated, or at all.
We discusshave entered into the Purchase Agreement with AMAK and certain other existing shareholders of AMAK (collectively, the “Purchasers”) pursuant to which we have agreed to sells our 33.3% equity interest in AMAK to the Purchasers. However, we cannot guarantee when, or whether the sale will be completed. The closing of the sale is subject to closing conditions, including the receipt of certain governmental approvals from the Saudi Arabian Deputy Ministry for Mineral Resources and the SIDF (with respect to release of our limited guarantee of the Loan (as described in Note 14 to the Consolidated Financial Statements)). If the closing conditions are not satisfied or waived (to the extent any such condition may be waived), in either a timely manner or at all, the closing of the sale may be delayed or may not be completed as contemplated, or at all, which could cause us not to realize some or all of these risksthe anticipated benefits of the transaction. In addition, the market price of our common stock may reflect an assumption that the pending sale will occur and on a timely basis, and the failure to do so may result in more detail belowa decline in no particular orderthe market price of priority.our common stock.

DependenceWe rely on a limited number of customers,

During 2017, sales to including one customer exceeded 10 percentthat represented more than 10% of SHR's revenues.  See the information regarding dependenceour consolidated revenue in 2019. A significant change in customer relationships or in customer demand for our products could materially adversely affect our results of operations, financial condition and cash flows.
We rely on a limited number of customers. Our largest customer, ExxonMobil and its affiliates, represented approximately 15.0% of our consolidated revenues in 2019. A significant reduction in sales to any of our key customers set forth in Part I, Item I Business under the caption "United States Specialty Petrochemical Operation". The total loss of a large volume customer could materially adversely affect our abilityresults of operations, financial condition and cash flows, and could result from our key customers further diversifying their product sourcing, experiencing financial difficulty or undergoing consolidation.
Our industry is highly competitive, and we may lose market share to marketother producers of specialty petrochemicals, specialty waxes or other products on a competitive basis and generate a profit.

Intense competition

The Company competes in the petrochemical industry. Accordingly, we are subject to intense competition among a large number of companies, both larger and smaller than us, many of which have financial capability, facilities, personnel and other resources greater than us. In the specialty products and solvents markets, the Company has one principal competitor in North America, Phillips 66.  Multiple competitors exist when searchingthat can be substituted for new business in other parts of the world.  We compete primarily on the basis of performance, price, quality, reliability, reputation, distribution, service, and account relationships. If our products, services, supportwhich may adversely affect our results of operations, financial condition and cash flows.
Our industry is highly competitive, and we face significant competition from both large international producers and from smaller regional competitors. Our competitors may improve their competitive position in our core markets by successfully introducing new products, improving their manufacturing processes or expanding their capacity or manufacturing facilities. Further, some of our competitors benefit from advantageous cost structure do not enablepositions that could make it increasingly difficult for us to compete successfully basedin certain markets. If we are unable to keep pace with our competitors' product and manufacturing process innovations, cost position or alternative value proposition, it could have a material adverse effect on anyour results of those criteria, our operations, resultsfinancial condition and prospects could be harmed.  The Company hascash flows.
In addition, we face increased competition from companies that may have greater financial resources and different cost structures, alternative values or strategic goals than us. We have a portfolio of businesses andacross which we must allocate our available resources, across these businesses while competing with companies thatmay specialize in one or moreonly certain of theseour product lines. As a result, we may invest less in certain areas of our businessesbusiness than our competitors, do, and thesesuch competitors may have greater financial, technical and marketing resources available to them than our businesses that compete against them. Industry consolidation may also affect competition by creating larger, more homogeneous and potentially stronger competitors in the markets in which we compete, and competitors also may affect our business by entering into exclusive arrangements with existing or potential customers or suppliers. We may have to continue to lower the prices of many of our products and services to stay competitive, while at the same time, trying to maintain or improve revenue and gross margin.

Loss of key employees, our inability to attract and retain new qualified employees or our inability to keep our employees

focused on our strategies and goals could have an adverse impact on our operations.

Changeskey employees in technology

Oura competitive industry could have a significant adverse impact on our operations. In addition, an important component of our competitive performance is our ability to maintain or enhanceoperate safely and efficiently, including our ability to manage expenses and minimize the production of low margin products on an on-going basis. This requires continuous management focus, including technological capabilities, developimprovements, safe operations, cost control and market products and applications that meet changing customer requirements, and successfully anticipate or respondproductivity enhancements. The extent to technological changes in a cost effective and timely mannerwhich we manage these factors will likely impact our future business success. We compete in a numberperformance relative to competition.
If the availability of areas including, but notour raw materials is limited, we may be unable to product quality, performance, and customer service.  Our inability to maintain a technological edge, innovate and improve our products could cause a decline in the demand and salesproduce some of our products and adversely impactin quantities sufficient to meet customer demand or on favorable economic terms, which could have an adverse effect on our results of operations, financial positioncondition and cash flows.
We use polyethylene waxes in our specialty waxes segment and use additional non-primary raw materials in the production of our products in the specialty petrochemicals segment and specialty waxes segment. Suppliers may not be able to meet our raw material requirements and we may not be able to obtain substitute supplies from alternative suppliers in sufficient quantities, on economic terms, or in a timely manner. A lack of timely availability of our raw materials in the quantities we require to produce our products could result in our inability to meet customer demand and could have a material adverse effect on our results of operations, financial condition and cash flows.
We are subject to numerous regulations that could require us to modify our current business practices and incur increased costs.
We are subject to numerous regulations, including customs and international trade laws, export control, data privacy, antitrust laws and zoning and occupancy laws that regulate manufacturers generally and/or govern the importation, promotion and sale of our products, the operation of our facilities and our relationship with our customers, suppliers and competitors. In addition, we face risk associated with trade protection laws, policies and measures and other regulatory requirements affecting trade and investment, including loss or modification of exemptions for taxes and tariffs, imposition of new tariffs and duties and import and export licensing requirements. If these laws or regulations were to change or were violated by our management, employees, suppliers, buying agents or trading companies, the costs of certain goods could increase, or we could experience delays in shipments of our goods, be subject to fines or penalties, or suffer reputational harm, which could reduce demand for our products and hurt our business and negatively impact our results of operations. In addition, changes in federal and state minimum wage laws and other laws relating to employee benefits could cause us to incur additional wage and benefits costs, which could negatively impact our profitability.
Legal requirements are frequently changed and subject to interpretation, and we are unable to predict the ultimate cost of compliance with these requirements or their effects on our operations. We may be required to make significant expenditures or modify our business practices to comply with existing or future laws and regulations, which may increase our costs and materially limit our ability to operate our business.
Increases in the costs of our raw materials could have an adverse effect on our financial condition and results of operations if those costs cannot be passed onto our customers.
Our results of operations are directly affected by the cost of raw materials. Since the cost of these primary raw materials comprise a significant amount of our total cost of goods sold, the selling prices for our products and therefore our total revenue is impacted by movements in these raw material costs, as well as the cost of other inputs. In the past we have experienced erratic and significant changes in the costs of these raw materials, the cost of which has generally correlated with changes in energy prices, supply and demand factors, and prices for natural gas and crude oil. Moreover, the price of raw materials may also be impacted by other external factors, including uncertainties associated with war, terrorist attacks, weather and natural disasters, health epidemics or pandemics, civil unrest, the effects of climate change or political instability, plant or production disruptions, strikes or other labor unrest, breakdown or degradation of transportation infrastructure used in the delivery of raw materials or changes in laws or regulations in any of the countries in which we have significant suppliers. In addition, product mix can have an impact on our overall unit selling prices, since we provide an extensive product offering and therefore experience a wide range of unit selling prices. Because of the significant portion of our cost of goods sold represented by these raw materials, our gross profit margins could be adversely affected by changes in the cost of these raw materials if we are unable to pass the increases on to our customers.
Due to volatile raw material prices, there can be no assurance that we can continue to recover raw material costs or retain customers in the future. For example, our logistics costs have increased substantially within the past three years, narrowing our profit margins. This may force us to increase our pricing, which could cause customers to consider competitors' products, some of which may be available at a lower cost. Significant loss of customers could result in a material adverse effect on our results of operations, financial condition and cash flows.

Climate change and greenhouse gas restrictions

DueIf we are unable to concern over the risk of climate change, a number of countries have adopted, or are considering the adoption of, regulatory frameworks to reduce greenhouse gas emissions. These include adoption of cap and trade regimes, carbon taxes, restrictive permitting, increased efficiency standards, and incentives or mandates for renewable energy. These requirements could make our products more expensive, lengthen project implementation times, and reduce demand for hydrocarbons, as well as shift hydrocarbon demand toward relatively lower-carbon sources such as natural gas. Current and pending greenhouse gas regulations may also increase our compliance costs, such as for monitoring or sequestering emissions.

Varying economic conditions

The demandaccess third-party transportation for our raw materials and finished products, and metals correlates closely with general economic growth rates.  The occurrence of recessions or other periods of low or negative growth will typicallywe may not be able to fulfill our obligations to our customers in a timely manner, which could have a directmaterial adverse impacteffect on our results.  Other factors that affect general economic conditions in the world or in a major region, such as changes in population growth rates or periods of civil unrest, also impact the demand for our products and metals.  Economic conditions that impair the functioning of financial markets and institutions also pose risks to us, including risks to the safety of our financial assets and to the ability of our partners and customers to fulfill their commitments to us.  In addition, the revenue and profitability of our operations have historically varied, which makes future financial results less predictable. Our revenue, gross margin and profit vary among our products, customer groups and geographic markets; and therefore, will likely be different in future periods than currently. Overall gross margins and profitability in any given period are dependent partially on the product, customer and geographic mix reflected in that period's net revenue. In addition, newer geographic markets may be relatively less profitable due to investments associated with entering those markets and local pricing pressures. Market trends, competitive pressures, increased raw material or shipping costs, regulatory impacts and other factors may result in reductions in revenue or pressure on gross margins of certain segments in a given period which may necessitate adjustments to our operations.

Transportation impediments

Although we try to anticipate problems with supplies of raw materials by planning ahead, any significant disruption could affect our ability to obtain raw materials at affordable costs which could adversely impact our results of operations, financial positioncondition and cash flows.

We maintain a number of owned trucks and trailers and leased railcars; however, we also rely upon transportation provided by third parties (including common carriers, rail companies and trans-ocean cargo companies) to receive raw materials used in the production of our products and to deliver finished products to our customers. Our accessWhile we attempt to offset the risks associated with third-party transportation issues, including by managing our supplies of raw materials, such mitigation efforts may not be successful. If we are unable to access third-party transportation at economically attractive rates, or at all, or if there is not guaranteed, andany other significant disruption in the availability of third-party transportation, we may not be unableable to transportobtain sufficient quantities of raw materials (on favorable terms, or at all) to match the pace of production and/or we may not be able to fulfill our productsobligations to our customers in a timely manner, in certain circumstances or at economically attractive rates. Disruptions in transportation are common.  Our inability to ship products in a timely and efficient mannerwhich could have a material adverse effect on our results of operations, financial condition and cash flows.
Failure to successfully consummate extraordinary transactions, including the integration of other businesses, assets, products or technologies, or realize the financial and strategic goals that were contemplated at the time of any such transaction may adversely affect our future business, results of operations and financial condition.
As part of our business strategy, we from time to time explore possible investments, acquisitions, strategic alliances, joint ventures, divestitures and outsourcing transactions (collectively, "extraordinary transactions") in order to further our business objectives. To pursue this strategy successfully, we must identify suitable candidates for, and successfully complete, extraordinary transactions, some of which may be large and complex, and manage post-closing issues such as the integration of acquired businesses or employees. The expense and effort incurred in exploring and consummating extraordinary transactions, the time it takes to integrate an acquisition or our failure to integrate businesses successfully, could result in additional and/or unexpected expenses and losses. We also may not be successful in negotiating the terms of any potential extraordinary transactions, conducting thorough due diligence, financing an extraordinary transaction or effectively integrating the acquired business, product or technology into our existing business and operations. Our due diligence may fail to identify all of the problems, liabilities or other shortcomings or challenges of an acquired business, product or technology. Moreover, we may incur significant expenses whether or not a contemplated extraordinary transaction is ultimately consummated.
Additionally, in connection with any extraordinary transaction we consummate, we many not fully realize all of the anticipated synergies and other benefits we expect to achieve (on our expected timeframe, or at all), and we may incur unanticipated expenses, write-downs, impairment charges or unforeseen liabilities that could negatively affect our business, financial condition and results of operations, disrupt relationships with current and new employees, customers and vendors, incur significant debt or have to delay or not proceed with announced transactions. Further, managing extraordinary transactions requires varying levels of management and employee resources, which may divert our attention from other business operations. We may also face additional challenges and costs after the consummation of the transaction, including those related to integrating or restructuring our operations, information management and other technology systems, while carrying on our ongoing business.
Adverse results of legal proceedings could materially adversely affect us.
We are subject to and may in the future be subject to a variety of legal proceedings and claims that arise out of the ordinary conduct of our business, including legal proceedings brought in non-U.S. jurisdictions. Results of legal proceedings cannot be predicted with certainty. Irrespective of its merits, litigation may be both lengthy and disruptive to our operations and may cause significant expenditure and diversion of management attention. We may be faced with significant monetary damages or injunctive relief against us that could have an adverse impact on our business and results of operations should we fail to prevail in certain matters.
Maintenance, expansion and refurbishment of our facilities and the development and implementation of new manufacturing processes involve significant risks which may adversely affect our business, results of operations, financial condition and cash flows.
Our facilities require periodic maintenance, upgrading, expansion, refurbishment or improvement. Any unexpected operational or mechanical failure, including failure associated with breakdowns and forced outages, could reduce our facilities' production capacity below expected levels which would reduce our revenues and profitability. Unanticipated expenditures associated with maintaining, upgrading, expanding, refurbishing or improving our facilities may also reduce profitability.
If we make any major modifications to our facilities, such modifications likely would result in substantial additional capital expenditures and may prolong the time necessary to bring the facility on line. We may also choose to refurbish or upgrade our facilities based on our assessment that such activity will provide adequate financial returns. However, such activities require time for development before commencement of commercial operations, and key assumptions underpinning a decision to make such an investment may prove incorrect, including assumptions regarding construction costs, demand growth and timing which could have a material adverse effect on our business, results of operations, financial condition and cash flows.

Chemical plantFinally, we may not be successful or efficient in developing or implementing new production processes. Innovation in production processes involves significant expense and carries inherent risks, including difficulties in designing and developing new process technologies, development and production timing delays, lower than anticipated manufacturing yields, and product defects. Disruptions in the production process can also result from errors, defects in materials, delays in obtaining or revising operating riskspermits and licenses, returns of product from customers, interruption in our supply of materials or resources and disruptions at our facilities due to accidents, maintenance issues, or unsafe working conditions, all of which could affect the timing of production ramps and yields. Production issues can lead to increased costs and may affect our ability to meet product demand, which could adversely impact our business, results of operations, financial condition and cash flows.

There are certain hazards and risks inherent in our operations that could adversely affect those operations and results of operations and financial condition.
As a manufacturer and distributor of diversified chemical products, our business is subject to operating risks common toinherent in chemical manufacturing, storage, handling and transportation. These risks include, but are not limited to, fires, explosions, inclementsevere weather and natural disasters, mechanical failure, unscheduled downtime, loss of raw materials or our products, transportation interruptions, remediation, chemical spills, terrorist acts or war, discharges or releases of toxic or hazardous substances or gases. These hazards can cause personal injury and loss of life, severe damage to, or destruction of, property and equipment and environmental contamination. In addition, our suppliers are also subject to similar risks that may adversely impact our production capabilities. A significant limitation on our ability to manufacture products due to disruption of manufacturing
operations or related infrastructure could have a material adverse effect on our financial condition and results of operations.operations and financial condition.
Hazardous material liability and risk

Our manufacturing and distribution of chemical products involves the controlled use of hazardous materials. Our operations, therefore, are subject to various associated risks, including chemical spills, discharges or releases of toxic or hazardous substances or gases, fires, mechanical failure, storage facility leaks and similar events. Our suppliers are subject to similar risks that may adversely impact the availability of raw materials. While we adapt our manufacturing and distribution processes and controls to minimize the environmental control standardsinherent risk of regulatory authorities,our operations, to promote workplace safety and to minimize the potential for human error, we cannot completely eliminate the risk of accidental contamination or injury from hazardous or regulated materials, including injury of our employees, individuals who handle our products or goods treated with our products, or others who claim to have been exposed to our products, nor can we completely eliminate the unanticipated interruption or suspension of operations at our facilities due to such events. We may be held liable for significant damages or fines in the event of contamination or injury, and such assessed damages or fines could have a material adverse effect on our financial performance and results of operations.operations and financial conditions. Our property, business interruption and casualty insurance may not fully insure us against all potential hazards incidental to our business.

Environmental regulation

We expect to continue to incur capital expenditures and operating costs as a result of our compliance with existing and future environmental laws and regulations.
Our industries areindustry is subject to extensive environmental regulation pursuantlaws and evolving regulations related to a varietythe protection of federalthe environment. These laws and state regulations.  Such environmental legislation imposes,regulations have tended to become more stringent over time, continue to increase in both number and complexity and affect our operations with respect to, among other things,things: the discharge of pollutants into the environment; emissions into the atmosphere (including greenhouse gas emissions); and restrictions, liabilities and obligations in connection with storage, transportation, treatment and disposal of hazardous substances and waste. LegislationWe are also requiressubject to laws and regulations that require us to operate and maintain our facilities to the satisfaction of applicable regulatory authorities. Costs to comply with these regulations are significant to our business.  FailureIn addition, failure to comply with these laws or regulations, or failure to obtain required permits from applicable regulatory authorities, may expose us to fines, penalties or interruptions in operations. To the extent these capital expenditures or operating costs are not ultimately reflected in the prices of our products and services, or that we are subject to fines, penalties or other interruptions in our operations, that couldour business, results of operations, financial condition and cash flows may be materialadversely affected.
If we are not able to continue the technological innovation and successful commercial introduction of new products, our customers may turn to other producers to meet their requirements, which may adversely affect our results of operations.operations, financial condition and cash flows.
Our industry and the markets into which we sell our products experience periodic technological change and ongoing product improvements. In addition, some of the finished goods our customers produce,may introduce new generations of their own products, adopt new or different risk profiles, or require new technological and increased performance specifications that would require us to develop customized products. Our future growth and profitability will depend on our ability to maintain or enhance technological capabilities, develop and market products and applications that meet changing customer requirements and successfully anticipate or respond to technological changes in a cost effective and timely manner. Our inability to maintain a technological edge, innovate and improve our products could cause a decline in the demand and sales of our products and adversely affect our results of operations, financial condition and cash flows.
Conditions in the global economy may adversely affect our results of operations, financial condition and cash flows.
The demand for our products have historically correlated closely with general economic growth rates. The occurrence of recessions or other periods of low or negative growth will typically have a direct adverse impact on our results of operations, financial condition and cash flows. Other factors that affect general economic conditions in the world or in a major region, such

as expandable polystyrene (EPS), arechanges in population growth rates or periods of civil unrest, weather and national disasters or health epidemics and pandemics also impact the demand for our products. Economic conditions that impair the functioning of financial markets and financial institutions also pose risks to us, including risks to the safety of our financial assets and to the ability of our partners and customers to fulfill their commitments to us.
In addition, the revenue and profitability of our operations have historically been subject to increasing scrutinyfluctuation, which makes future financial results less predictable. Our revenue, gross margin and profit vary among our products, customer groups and geographic markets. Overall gross margins and profitability in any given period are dependent partially on the product, customer and geographic mix reflected in that period's net revenue. In addition, newer geographic markets may be relatively less profitable due to investments associated with entering those markets and local pricing pressures. Market trends, competitive pressures, increased raw material or shipping costs, regulatory impacts and other factors may result in reductions in revenue or pressure on gross margins of certain segments in a given period which may necessitate adjustments to our operations.
The adoption of climate change legislation or regulation which could lead to a reductionresult in increased operating costs and reduced demand for our products.

Safety, business controls, environmental and cyber risk management

Our results depend upon management's ability to minimize the inherent risksThe nature of our operations to control effectively our business activities and to minimize the potential for human error.  We apply rigorous management systems and continuous focus to workplace safety and to avoid spills or other adverse environmental events.  Substantial liabilities and other adverse impacts could result if our systems and controls do not function as intended.  Business risks also include the risk of cyber security breaches.  If our systems for protecting against cyber security risks prove to be insufficient, we could be adversely affected by having our business systems compromised, our proprietary information altered, lost or stolen, or our business operations disrupted.

The use of a new enterprise resource planning system could cause a financial statement error not to be detected

During 2017 we implemented a new enterprise resource planning ("ERP") system at SHR to replace a previous system.  This was a complex process, and the new system resulted in changes to our internal controls over financial reporting, including disclosure controls and procedures.  The ongoing improvements being made to the new ERP system could adversely affect the effectiveness of our internal controls over financial reporting.

Borrowing ability and indebtedness

In 2014 we entered into an Amended and Restated Credit Agreement ("ARC").  This agreement contains restrictive clauses which may limit our activities, and operational and financial flexibility. We may not be able to borrow under the ARC if an event of default under the terms of the facility occurs.  The ARC contains a number of restrictions that limit our ability, among other things, andmake us subject to certain limited exceptions, to incur additional indebtedness, pledge our assets as security, guarantee obligationslegislation or regulations affecting the emission of third parties, make investments, undergo a merger or consolidation, dispose of assets or materially change our line of business.
In addition, the ARC requires us to meet certain financial ratios, including fixed charge coverage, total leverage ratio, and asset coverage.  These non-GAAP measures of liquidity are defined in the ARC. Our ability to meet these financial covenants depends upon the future successful operating performance of the business. If we fail to comply with financial covenants, we would be in default under the ARC and the maturity of our outstanding debt could be accelerated unless
we were able to obtain waivers from our lenders. If we were found to be in default under the ARC, it could adversely impact our results of operations, financial position and cash flows.

Regulatory and litigation

Even in countries with well-developed legal systems where we do business, we remain exposed to changes in law that could adversely affect our results, such as increases in taxes, price controls, changes in environmental regulations or other laws that increase our cost of compliance, and government actions to cancel contracts or renegotiate items unilaterally.  We may also be adversely affected by the outcome of litigation or other legal proceedings, especially in countries such as the United States in which very large and unpredictable punitive damage awards may occur.  AMAK's mining and exploration leases are subject to the risk of termination if AMAK does not comply with its contractual obligations.  Further, our investment in AMAK is subject to the risk of expropriation or nationalization. If a dispute arises, we may have to submit to the jurisdiction of a foreign court or panel or may have to enforce the judgment of a foreign court or panel in that foreign jurisdiction.  Because of our substantial international investment, our business is affected by changes in foreign laws and regulations (or interpretation of existing laws and regulations) affecting our industries, and foreign taxation. We will be directly affected by the adoption of rules and regulationsgreenhouse gases. The U.S. Environmental Protection Agency has promulgated (and the interpretations of such rules and regulations) regarding the exploration and development of mineral properties for economic, environmental and other policy reasons. We may be required to make significant capital expenditures to comply with non-U.S. governmental laws and regulations.  It is also possible that these laws and regulations may in the future add significantlypromulgate) regulations applicable to our operating costsprojects involving greenhouse gas emissions above a certain threshold, and the U.S. and certain states within the U.S. have enacted, or may significantly limit our business activities. Additionally, our abilityare considering, limitations on greenhouse gas emissions. Jurisdictions outside the U.S. are also addressing greenhouse gases by legislation or regulation. In addition, efforts have been made and continue to compete inbe made at the international marketlevel toward the adoption of international treaties or protocols that would address global greenhouse gas emissions. These limitations may be adversely affected by non-U.S. governmental regulations favoringinclude the adoption of cap and trade regimes, carbon taxes, restrictive permitting, increased efficiency standards and incentives or requiring the awarding of leases, concessionsmandates for renewable energy. Any such requirements could make our products more expensive, lengthen project implementation times and other contractsreduce demand for hydrocarbons, as well as shift hydrocarbon demand toward relatively lower-carbon sources. Such legislation, regulation, treaties or exploration licensesprotocols may also increase our compliance costs, such as for monitoring or sequestering emissions.
We are exposed to local contractors or requiring foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction.  We are not currently aware of any specific situations of this nature, but there are always opportunities for this type of difficulty to arisebusiness risks in the international business environment.

Loss of key personnel and management effectiveness

In order to be successful, we must attract, retain and motivate executives and other key employees including those in managerial, technical, sales, and marketing positions. We must also keep employees focused on our strategies and goals. The failure to hire, or loss of, key employeesdifferent countries, which could have a significant adverse impact on operations.  An important component of our competitive performance is our ability to operate efficiently including our ability to manage expenses and minimize the production of low margin products on an on-going basis.  This requires continuous management focus including technological improvements, cost control and productivity enhancements.  The extent to which we manage these factors will impact our performance relative to competition.

Risk associated with extraordinary transactions

As part of our business strategy, we sometimes engage in discussions with third parties regarding possible investments, acquisitions, strategic alliances, joint ventures, divestitures and outsourcing transactions ("extraordinary transactions") and enter into agreements relating to such extraordinary transactions in order to further our business objectives.  In order to pursue this strategy successfully, we must identify suitable candidates for and successfully complete extraordinary transactions, some of which may be large and complex, and manage post-closing issues such as the integration of acquired companies or employees. Integration and other risks of extraordinary transactions can be more pronounced for larger and more complicated transactions, or if multiple transactions are pursued simultaneously. If we fail to identify and complete successfully extraordinary transactions that further our strategic objectives, we may be required to expend resources to develop products and technology internally, we may be at a competitive disadvantage or we may be adversely affected by negative market perceptions, any of which may have a material adverse effect on our revenue, gross margin and profitability. Integration issues are complex, time-consuming and expensive and, without proper planning and implementation, could significantly disrupt our business. The challenges involved in integration include:

Combining product offerings and entering into new markets in which we are not experienced;

Convincing customers and distributors that the transaction will not diminish client service standards or business focus, preventing customers and distributors from deferring purchasing decisions or switching to other suppliers (which could result in our incurring additional obligations in order to address customer uncertainty), and coordinating sales, marketing and distribution efforts;

Minimizing the diversion of management attention from ongoing business concerns;

Persuading employees that business cultures are compatible, maintaining employee morale and retaining key employees, engaging with employee works councils representing an acquired company's non-U.S. employees, integrating employees into the Company, correctly estimating employee benefit costs and implementing restructuring programs;

Coordinating and combining administrative, manufacturing, and other operations, subsidiaries, facilities and relationships with third parties in accordance with local laws and other obligations while maintaining adequate standards, controls and procedures;

Achieving savings from supply chain integration; and

Managing integration issues shortly after or pending the completion of other independent transactions.

We periodically evaluate and enter into significant extraordinary transactions on an ongoing basis. We may not fully realize all of the anticipated benefits of any extraordinary transaction, and the timeframe for achieving benefits of an extraordinary transaction may depend partially upon the actions of employees, suppliers or other third parties. In addition, the pricing and other terms of our contracts for extraordinary transactions require us to make estimates and assumptions at the time we enter into these contracts, and, during the course of our due diligence, we may not identify all of the factors necessary to estimate our costs accurately. Any increased or unexpected costs, unanticipated delays or failure to achieve contractual obligations could make these agreements less profitable or unprofitable. Managing extraordinary transactions requires varying levels of management resources, which may divert our attention from other business operations. These extraordinary transactions also have resulted and in the future may result in significant costs and expenses and charges to earnings. Moreover, we have incurred and will incur additional depreciation and amortization expense over the useful lives of certain assets acquired in connection with extraordinary transactions, and, to the extent that the value of goodwill or intangible assets with indefinite lives acquired in connection with an extraordinary transaction becomes impaired, we may be required to incur additional material charges relating to the impairment of those assets. In order to complete an acquisition, we may issue common stock, potentially creating dilution for existing stockholders, or borrow, affecting our financial condition and potentially our credit ratings. Any prior or future downgrades in our credit rating associated with an acquisition could adversely affect our ability to borrow and result in more restrictive borrowing terms. In addition, our effective tax rate on an ongoing basis is uncertain, and extraordinary transactions could impact our effective tax rate. We also may experience risks relating to the challenges and costsresults of closing an extraordinary transaction and the risk that an announced extraordinary transaction may not close. As a result, any completed, pending or future transactions may contribute to financial results that differ from the investment community's expectations in a given quarter.

Guaranteeing performance by others

From time to time, we may be required or determine it is advisable to guarantee performance of loan agreements by others in which we maintain a financial interest. In such instances, if the primary obligor is unable to perform its obligations, we might be forced to perform the primary obligor's obligations which could negatively impact our financial interests.

International market challenges

operations.
Although we do not have production operations and assets outside of the US,U.S., we do have a global portfolio of customers and thus we are subject to a variety of international market risks including, but not limited to, to:
ongoing instability or changes in a country's or region's economic or political conditions, including inflation, recession, interest rate fluctuations, civil unrest and actual or anticipated military or political conflicts (including the potential impact of continued hostilities and conflict in Yemen on the operations of AMAK);

Additional tax liabilities

We are subject to income taxes and state taxes in the United States.  Significant judgment is required in determining our provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different to that which is reflected in our consolidated financial
statements. Should any tax authority take issue with our estimates, our results of operations, financial position, and cash flows could be adversely affected.

Public Law No. 115-97 known as the U.S. Tax Cuts and Jobs Act ("TCJA") was enacted on December 22, 2017, and introduces significant changes to U.S. income tax law.  Accounting Standards Codification 740, Accounting for Income Taxes, requires companies to recognize the effects of tax law changes in the period of enactment. Effective in 2018, the TCJA made a number changes, such as reducing the U.S. statutory tax rate from 35.0%regulatory or legal environment;
differing technology standards or customer requirements;
import, export or other business licensing requirements or requirements relating to 21.0%, creating new taxes on certainmaking foreign sourced earnings and certain related-party payments,direct investments, which are referred to as the global intangible low taxed income tax and the base erosion tax, respectively, establishing a dividends received deduction for dividends paid by foreign subsidiaries to the U.S., the elimination or limitation of certain deductions, and imposing a mandatory tax on previously unrepatriated earnings accumulated offshore.  Due to the timing of the new tax law provided in the TCJA and the substantial changes it brings, the Staff of the Securities and Exchange Commission issued Staff Accounting Bulletin No. 118, which provides registrants with a measurement period to report the impact of the new US tax law. As a result, the recorded and estimated impacts of the TCJA may change in future periods, which may adverselycould affect our estimates, our results of operations, financial position and cash flows.

Risk associated with activist shareholders

While we seek to actively engage with our shareholders and consider their views on business and strategy, we could be subject to actions or proposals from our shareholders that do not align with our business strategies or the interests of our other shareholders. Responding to these shareholders could be costly and time-consuming, disrupt our business and operations, and divert the attention of our senior management. Furthermore, uncertainties associated with such activities could negatively impact our ability to execute our strategic plan, retain customerobtain favorable terms for labor and skilled personnelraw materials or lead to penalties or restrictions;
data privacy regulations;
risk of non-compliance with the U.S. Foreign Corrupt Practices Act or similar anti-bribery legislation in other countries by agents or other third-party representatives;
risk of nationalization of private enterprises by foreign governments (including the risk that AMAK's mining and affect long-term growth. In addition, such activitiesexploration leases may cause our stock price to fluctuate based on temporarybe terminated by the Saudi Ministry of Petroleum and Minerals);
foreign currency exchange restrictions and fluctuations;

Economicdifficulties associated with repatriating cash generated or held abroad in a tax-efficient manner and political instability; terrorist acts; warchanges in tax laws; and other political unrest

The conflictfluctuations in freight costs and hostilities in Yemen could disrupt or interfere with the operations of AMAK whose corporate offices and mining assets are located in Najran province of Saudi Arabia.  In addition, the potential for additional future terrorist acts and other recent events, including ISIS terrorist related activities and civil unrestdisruptions in the Middle East, have caused uncertainty in the world's financial marketstransportation and have significantly increased global political, economicshipping infrastructure at important geographic points of exit and social instability, including in Saudi Arabia, a country in which we have a substantial investment.  It is possible that further acts of terrorism may be directed against the United States domestically or abroad,entry for our products and such acts of terrorism could be directed against our investment in those locations.  shipments.
Such economic and political uncertainties may materially and adversely affect our business, financial condition or results of operations in ways that cannot be predicted at this time. Although it is impossible to predict the occurrences or consequences of any such events, they could result in a decrease in demand for our products, make it difficult or impossible to deliver products to our customers or to receive componentsraw materials from our suppliers and create delays and inefficiencies in our supply chain and result in the need to impose employee travel restrictions.chain. We are also predominantly uninsured for losses and interruptions caused by terrorist acts, conflicts and wars. Our
Domestic or international natural disasters or other severe weather events, health epidemics or pandemics or terrorist attacks may disrupt our operations or those of our customers or suppliers, decrease demand for our products or otherwise have an adverse impact on our business.
Chemical related assets, and U.S. corporations such as ours, may be at a greater risk of future revenue, gross margin, expensesterrorist attacks (including both physical attacks and cyber–attacks) than other possible targets in the U.S. Moreover, extraordinary events such as natural disasters, other severe weather events or global or local health epidemics or pandemics could result in significant damage to our facilities and/or disruption of our operations and may negatively affect local economies, including those of our customers or suppliers. The occurrence of such events cannot be predicted, although their occurrence can be expected to continue to adversely impact the economy in general and our specific markets.
The resulting damage from a natural disaster, other severe weather events or terrorist attack could include loss of life, property damage or site closure. Several of our facilities are located in regions where natural disasters and other severe weather events have previously disrupted, and may in the future disrupt, our ability to manufacture and deliver products from certain facilities. Any damage resulting in stoppage or reduction of our facilities’ production capacity could reduce our revenues and any unanticipated capital expenditures to repair such damage (to the extent not covered by our insurance policies) may reduce profitability. Any, or a combination, of these factors could also adversely impact our results of operations, financial condition and cash flows.
In addition, global or local heath epidemics and pandemics may result in disruption of our operations or those of our customers or suppliers. For example, the COVID-19 (commonly referred to as the coronavirus) outbreak originating in China at the beginning of 2020 has resulted in closures, quarantines, travel restrictions and extended shutdown of certain businesses in regions in which we operate and could also substantially interfere with general commercial activity related to our supply chain and customer base. This could have a material adverse effect on our results of operations, financial condition and cash flows. At this point, the extent of the impact on our results as a result of the coronavirus outbreak is uncertain.
Increased information systems security threats and more sophisticated and targeted computer crime could pose a risk to our systems, networks, products and services.
Increased information systems security threats and more sophisticated, targeted computer crime pose a risk to the security of our systems and networks and the confidentiality, availability, and integrity of our data, operations, and communications. While we attempt to mitigate these risks by employing a number of measures, including security measures, employee training, comprehensive monitoring of our networks and systems, and maintenance of backup and protective systems, if these measures prove inadequate, we could be adversely affected by, among other things, loss or damage of intellectual property, proprietary and confidential information, and communications or customer data, having our business operations interrupted and increased costs to prevent, respond to, or mitigate these cyber security threats. Any significant disruption or slowdown of our systems could cause customers to cancel orders or standard business processes to become inefficient or ineffective, which could adversely affect our results of operations, financial condition and cash flows.
Changes in tax laws or exposure to additional income tax liabilities could affect our future profitability.
Factors that could materially affect our future effective tax rates include but are not limited to:
changes in tax laws or the regulatory environment;
changes in accounting and tax standards or practices;
changes in the composition of operating income by tax jurisdiction; and
our operating results before taxes.
We are subject to income taxes and state taxes in the U.S. Significant judgment is required in determining our provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our tax estimates are reasonable, the final determination of tax audits and any

related litigation could be materially different to that which is reflected in our consolidated financial statements. Should any tax authority take issue with our estimates, our results of operations, financial condition and cash flows could be adversely affected.
On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law making significant changes to the Internal Revenue Code. In particular, sweeping changes were made to the U.S. taxation of foreign operations. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a quasi–territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings. The Company completed its analysis of the impact of the Tax Act and has finalized all estimates previously considered provisional under Staff Accounting Bulletin 118 in the fourth quarter of 2018. The changes in tax law under the Tax Act are complex and regulations governing the implementation continue to be issued. While the Company believes it has correctly accounted for the impact of the Tax Act, guidance continues to be issued and may differ from our interpretation based on existing facts and circumstances.
We are subject to examination by federal and state tax authorities. While we regularly assess the likelihood of favorable or unfavorable outcomes resulting from examinations by the IRS and other tax authorities to determine the adequacy of our provision for income taxes, there can be no assurance that the actual outcome resulting from these examinations will not materially adversely affect our financial condition and operating results.
AMAK is also subject to various taxes in Saudi Arabia. While AMAK currently benefits from certain tax credits that reduce its overall tax liability, there can be no assurance that relevant tax authorities will continue to maintain such credits. In addition, there can be no assurances that future changes in tax law in Saudi Arabia will not result in increased tax liability to AMAK. A material increase in tax liability could have an adverse effect on AMAK's results of operations and financial condition, which may in turn have an adverse effect on our investment in AMAK.
Implementation of changes to our enterprise resource planning ("ERP") system may adversely affect our business and results of operations or the effectiveness of internal controls over financial reporting.
During 2017, we implemented a new ERP system at our specialty petrochemicals facility in order to better manage our business, and we continue to implement additional improvements to the system. ERP implementations are complex and time-consuming projects that involve substantial expenditures on system software and implementation activities over a significant period of time. If we do not effectively implement changes to ERP system, or if the system does not operate as intended, it could adversely affect our financial reporting systems and our ability to produce financial reports, the effectiveness of internal controls over financial reporting (including our disclosure controls and procedures), and our business and results of operations.
Certain activist stockholders actions could cause us to incur expense and hinder execution of our strategy.
While we seek to actively engage with our stockholders and consider their views on business and strategy, we could be subject to actions or proposals from our stockholders that do not align with our business strategies or the interests of our other stockholders. Responding to these stockholders could be costly and time-consuming, disrupt our business and operations and divert the attention of our management. Furthermore, uncertainties associated with such activities could negatively impact our ability to execute our strategic plan, retain customers and skilled employees and affect long-term growth. In addition, such activities may cause our stock price to fluctuate based on temporary or speculative market perceptions that do not necessarily reflect our business operations.
The covenants in the instruments that govern our outstanding indebtedness may limit our operating and financial flexibility.
The covenants in the instruments that govern our outstanding indebtedness limit our ability to, among other things:
incur indebtedness and liens;
make loans and investments;
prepay, redeem or repurchase debt;
engage in acquisitions, consolidations, asset dispositions, sale-leaseback transactions and affiliate transactions;
change our business;
amend some of our debt agreements; and
grant negative pledges to other creditors.
In addition, the ARC Agreement (as defined herein) also could suffer duehas financial covenants that require TOCCO to maintain a varietymaximum Consolidated Leverage Ratio and minimum Consolidated Fixed Charge Coverage Ratio (each as defined in the ARC Agreement). See Part II, Item 7. Management's Discussion and Analysis of international factors, including:Financial Condition and Results of Operations under the heading "Liquidity and Capital Resources."

Upon the occurrence of an event of default under any of the agreements governing our indebtedness, the lenders could elect to declare all amounts outstanding to be due and payable and exercise other remedies as set forth in the agreements. Further, an event of default or acceleration of indebtedness under one instrument may constitute an event of default under another instrument. If any of our indebtedness were to be accelerated, there can be no assurance that our assets would be sufficient to repay this indebtedness in full, which could have a material adverse effect on our ability to continue to operate as a going concern.
Our substantial indebtedness could limit cash flow available for our operations and could adversely affect our ability to service debt or obtain additional financing if necessary.
As of December 31, 2019, we had $3 million in borrowings outstanding under our revolving credit facility (the "Revolving Facility") and $80.9 million in borrowings outstanding under our term loan facility (the "Term Loan Facility" and, together with the Revolving Facility, the "Credit Facilities"). Pursuant to the terms of the amended and restated credit agreement (as amended to the date hereof, the "ARC Agreement") governing the Credit Facilities, we also have the option, at any time, to request an increase to the commitment under the Revolving Facility and/or the Term Loan Facility by an additional amount of up to $50.0 million in the aggregate, subject to lenders acceptance of the increased commitment and other conditions.
Although the agreements governing our existing indebtedness contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of important exceptions, and additional indebtedness that we may incur from time to time to finance projects or for other reasons in compliance with these restrictions could be substantial. If we incur significant additional indebtedness, the related risks that we face could increase.
Our current, or any future, indebtedness could:
limit our flexibility in planning for, or reacting to, changes in the markets in which we compete;
place us at a competitive disadvantage relative to our competitors with less indebtedness;
limit our ability to reinvest in our business;
render us more vulnerable to general adverse economic, regulatory and industry conditions; and

require us to dedicate a substantial portion of our cash flow to service our indebtedness.
•     Fluctuations in freight costsOur ability to meet our cash requirements, including our debt service obligations, is dependent upon our ability to maintain our operating performance, which will be subject to general economic and disruptions in the transportationcompetitive conditions and shipping infrastructure at important geographic pointsto financial, business and other factors, many of exitwhich are beyond our control. We cannot provide assurance that our business will generate sufficient cash flow from operations to fund our cash requirements and entry fordebt service obligations.
To service our productscurrent, and shipments.any future, indebtedness, we will require a significant amount of cash, which may adversely affect our future results.

Business disruption

If our business does not generate sufficient cash flow from operations or manmade disastersif future borrowings are not available to us in an amount sufficient to enable us to pay our indebtedness, or business interruptions, for someto fund our other liquidity needs, we may need to refinance all or a portion of our indebtedness (or otherwise seek amendment or relief from the terms of our indebtedness), on or before the maturity thereof, sell assets, reduce or delay capital investments or seek to raise additional capital, any of which could have a material adverse effect on our operations. We might not generate sufficient cash flow to repay indebtedness as currently anticipated. In addition, we may not be self-insured. The occurrence ofable to effect any of these actions, if necessary, on commercially reasonable terms or at all. Our ability to restructure or refinance our indebtedness, will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of our indebtedness could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business disruptions could harmoperations. The terms of existing or future debt instruments may limit or prevent us from taking any of these actions. Our inability to generate sufficient cash flow to satisfy our revenuedebt service obligations, or to refinance or restructure our obligations on commercially reasonable terms or at all, would have a material adverse effect on our business, results of operations and financial conditionconditions.
Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Borrowings under the Credit Facilities are, and additional borrowings in the future may be, at variable rates of interest that expose us to interest rate risk. If interest rates increase, our costsdebt service obligations on the variable rate indebtedness will increase even though the amount borrowed will remain the same, and expenses.our net income and cash flows, including cash available for servicing our indebtedness, will correspondingly decrease. We may in the future enter into, interest rate swaps for our variable rate debt whereby we exchange floating for fixed rate interest payments in order to reduce exposure to interest rate volatility. However, any interest rate swaps into which we enter may not fully mitigate our interest rate risk.

We from time to time are subject to contingent liabilities. If any contingent liabilities become actual liabilities, our financial condition may be adversely affected.
Excess products

An important component ofWe are subject to various contingent liabilities that may affect our competitive performance isliquidity and our ability to minimizemeet our obligations, including our limited corporate guarantee to SIDF in connection with AMAK's Loan to fund mining operations. To the production of low margin products on an on-going basis.  Although the hydrocarbon constituents comprising the petrochemical feedstock we use may vary somewhat over time, they tend to fall into relatively narrow percentage bands as compared to overall feedstock composition.  By nature of the fractionation process that we utilize, if we make one product, we make them all; therefore, when we receive a significant order for a particular finished product, additional products may be manufactured necessitating sales into secondary, lower margin markets.  We continue to investigate options to maintain or improve margins.  We are in the process of constructing an advanced reformer unit with a capacity of 4,000 barrels per day which will allow us to upgrade the valueextent any of our byproducts in order to maximize margins.  The unit is expected to start up during the third quarter of 2018.

An impairment of goodwill could negatively impactcurrent or future contingent liabilities become actual liabilities, it may have an adverse effect on our financial results

At least annually, we assess goodwill for impairment.  If an initial qualitative assessment identifies that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, additional quantitative testing is performed. We may also elect to skip the qualitative testing and proceed directly to quantitative testing.  If the quantitative testing indicates that goodwill is impaired, the carrying value of goodwill is written down to fair value with a charge against earnings.  Since we utilize a discounted cash flow methodology to calculate the fair value of our operating units, continued weak demand for a specific product line or business could result in an impairment charge.  Accordingly, any determination requiring the write-off of a significant portion of goodwill could negatively impact our results of operations.

Dependence on AMAK management

We rely upondo not control the activities of AMAK and are dependent on AMAK's management and Board to employ various respected engineering and financial advisors to assist in the development and evaluationboard of the mining projects in Saudi Arabia.  Notwithstanding the utilization of any outside consultants, our risk will continue to and will ultimately depend upon AMAK's ability to use consultants and experienced personnel to manage the operation in Saudi Arabia.

Inability to control AMAK activities

directors.
Although we believe that we have significant influence over the operating and financial policies of AMAK, we do not control AMAK's activities. The extent to which we are able to influence specific operating and financial decisions depends on our ability to persuade other AMAK board members and management regarding these policies. Our ability to persuade them may be adversely affected by cultural differences, differing accounting and management practices and differing governmental laws and regulations,regulations. In addition, we rely upon AMAK's management and board of directors to direct the fact that theoperations of AMAK, mining project is halfway around the world from our main base of operationsincluding employing various engineering and financial advisors to assist in the United States.

Further, as described above under "Item 1: Business",development and evaluation of the Company was required to execute and deliver a limited corporate guarantee to SIDFmining projects in connection with AMAK's Loan from SIDF to fund mining operations.  IfSaudi Arabia. We also rely on management of AMAK
were to default on its payment obligations under the Loan, the Company may be required to make payments to SIDF under the limited corporate guarantee.

Inability to recoup investment in AMAK

We will only recover our investment in AMAK through the receipt of dividends from AMAK or the sale of part or all of our interest in AMAK. There is a risk that we will be unable to recover our investment in AMAK if AMAK is not profitable, or if AMAK's Board of Directors chooses not to declare dividends even if AMAK is profitable.  With respect to the sale of part or all of our interest in AMAK, under Saudi Arabian law, AMAK must sell a portion of its equity to the public once AMAK has been profitable for two years. While the proceeds of such a sale might allow us to recover our investment in AMAK, there is no assurance that AMAK will achieve the profitability required for such a public sale, or that the market conditions for any such public sale will be favorable enough to allow us to recover our investment.

AMAK's inability to provide timely financial information

In the event that AMAK is unable to provide timely, accurate financial information to us,required for inclusion with our ability to file reports filed with the Securities and Exchange Commission within required deadlines couldSEC.
There can be affected and our standing on the New York Stock Exchange and in the investment community could suffer.

Cancellation of the current mining leases held by AMAK

In the eventno assurance that the Saudi Ministry of Petroleum and Minerals cancels the current leases, AMAK shareholders including us could lose their investment or be forced to sell for a loss.

AMAK could suffer sustained operational difficulties

Operating difficulties are many and various, ranging from unexpected geological variations that could result in significant ground or containment failure to breakdown of key capital equipment.  Reliable roads, rail networks, ports, power generation and transmission, and water supplies are required to access and conduct AMAK's operations.  AMAK transports all of its products first by truck and then by sea.  Limitations or interruptions in transport infrastructure could impede its ability to deliver products.  Although going forward, operations will be owner-managed, availability of sufficiently skilled operators, engineers, geologists and maintenance technicians in Saudi Arabia can from time to time be severely limited.

AMAK may have fewer mineral reserves than its estimates indicate

AMAK's reserves estimations may change substantially if new information subsequently becomes available.  Fluctuations in the price of commodities, variation in production costs or different recovery rates may ultimately result in AMAK's estimated reserves being revised.  If such a revision were to indicate a substantial reduction in proven or probable reserves at one or more of AMAK's projects, it could negatively affect our investment in AMAK.

AMAK will not be negatively impacted by the decisions made by AMAK's management and board of directors regarding AMAK's activities, including with respect to the selection and use of consultants and experienced personnel to manage the operation in Saudi Arabia.
Cost pressures could negatively impact AMAK's operating margins and expansion plans

plans.
Cost pressures may continue to occur across the resources industry. As the prices for AMAK's products are determined by the global commodity markets in which it operates, AMAK does not generally have the ability to offset these cost pressures through corresponding price increases, which can adversely affect its operating margins or require changes in operations, including, but not limited to, temporary planned shutdowns. Notwithstanding AMAK's efforts to reduce costs, and a number of key cost inputs being commodity price-linked, the inability to reduce costs and a timing lag may adversely impact AMAK's operating margins for an extended period.

We may be unable to recover our investment in AMAK, which could adversely affect our results of operations and financial condition.
We will only recover our investment in AMAK through the receipt of distributions or future share repurchases from AMAK or the sale of part or all of our interest in AMAK. If AMAK does not continue to be profitable, our ability to recover our investment will be adversely affected. Moreover, if AMAK continues to be profitable, there can be no assurance that the board of directors of AMAK will determine that it is in the best interests of AMAK and its shareholders to make distributions to its shareholders or to initiate additional share repurchases. In addition, we understand that AMAK is required to sell a portion of its equity to the public once AMAK has been profitable for two years. While the proceeds of such a sale might allow us to recover our investment in AMAK, there is no assurance that the market conditions for any such public sale will be favorable enough to allow us to recover our investment or that some or all of our shares in AMAK will be include in any such sale. To the extent we are unable to recover our investments in AMAK, our results of operations and financial condition may be adversely affected.
AMAK may have fewer mineral reserves than its estimates indicate.
Fluctuations in the price of commodities, variation in production costs or different recovery rates could result in AMAK's estimated reserves being revised in the future. If such a revision were to indicate a substantial reduction in proven or probable reserves at one or more of AMAK's projects, it could adversely affect our investment in AMAK.

Investment in AMAK

As of December 31, 2017,2019, we owned a 33% interest in AMAK.

Prior to December 2008, we held a thirty (30) yearthirty-year mining lease (which commenced on May 22, 1993) covering an approximate 44 square kilometer area in Najran Province in southwestern Saudi Arabia. The lease carried an option to renew or extend the term of the lease for additional periods not to exceedexceeding twenty (20) years. The lease and other related assets located in Saudi Arabia were contributed to AMAK in December 2008. The above-ground ore processing facility became fully operational during the second half of 2012.   Late in the fourth quarter of 2015 AMAK temporarily closed the operation to preserve the assets in the ground while initiating steps to improve efficiencies and optimize operations. The facility resumed operation in the fourth quarter of 2016 and operating rates, metal recoveries and concentrate quality improvedcontinued to improve steadily throughout 2017.

since.
AMAK shipped approximately 28,000, 16,000,65,000, 58,000, and 51,00028,000 metric tons of copper and zinc concentrate to outside smelters during 2017, 20162019, 2018 and 2015,2017, respectively. In 2014 AMAK initiated operation of its precious metal recovery circuit at the mill and produced gold and silver doré intermittently through 2014 and 2015. The precious metals circuit was recommissioned in fourth quarter of 2017 and is expected to produceproduced commercial quantities of gold and silver bearing doré in 2018.

The facility includes an underground mine, ore-treatment plant and related infrastructures. The ore-treatment plant is comprised of primary crushing, ore storage, SAG milling and pebble crushing, secondary ball milling, pre-flotation, copper and zinc flotation, concentrate thickening, tailings filtration, cyanide leaching, reagent handling, tailings dam and utilities. Related infrastructure includes a 300 men400 man capacity camp for single status accommodation for expatriates and Saudi employees, an on-site medical facility, a service building for 300 employees, on-site diesel generation of 10 megawatts, potable water supply, sewage treatment plant and an assay laboratory. The facilities at the Port of Jazan are comprised of unloading facilities, concentrate storage and reclamation and ship loading facilities.

Three mineralized zones, the Saadah, Al Houra and Moyeath, were outlined by initial diamond drilling. Based onMineable Reserves were estimated from Al Masane Mineral Resource Model developed by the original 1994 WGM feasibility studyAMAK Geology team as updated in 1996, 2005 and 2009 theof December 31, 2019. The following tables set forth a summary of the diluted recoverable, proven and probable mineralized materials of AMAK in the Al Masane area along with the estimated average grades of these mineralized materials as adjusted to reflect production that began in July 2012:January 2020:

For purposes of calculating proven and probable mineralized materials, a dilution of 5%23.54% at zero grade on the Saadah zone, and 15% at zero grade on the Al Houra and Moyeath zones was assumed. AThe mining method used at the project is predominantly long-hole open stoping (LHOS) with backfill, using a 96% mine recovery of 80% was used forfactor and a stope dilution factor incorporated in the Saadah zonereserve mine plan (as applied to the Mineral Resource model prior to consideration as Mineral Reserves) between 7% and 88% for22% as per geotechnical recommendations (based on the Al Houra and Moyeath zones.stope location). Mining dilution is the amount of wall-rock adjacent to the ore body that is included in the ore extraction process. Base case cutoffs used were 5.0% zinc1.01% copper equivalent. Ore reserves were estimated using metal prices of USD $0.85$1.13 per pound for zinc, $2.50$2.95 per pound for copper, $800$1,300 per ounce for gold and $12.0$18.00 per ounce for silver.silver, respectively.

Our rights to obtain additional mining licenses to other adjoining areas were also transferred to AMAK in December 2008 as part of our initial capital contribution. AMAK received formal approval in November 2015 of an additional 151 square kilometerskm2 or 37,313 acres of territory relatively close to the current mine. The new territory comprises the Guyan and Qatan exploration licenses covering 151 square kilometerskm2 and within the Guyan exploration license, a 10 square kilometerskm2 or 2,471 acre mining lease which has potential for significant gold recovery. Some exploration holes were drilled in both Guyan and Qatan up to 40 years ago, but no reserves were attributed to these areas. Exploration activities were restarted in both of these areas during 2016, and SRK Consulting prepared a JORC

Joint Ore Reserves Committee ("JORC") compliant report in May 2017August 2019 showing approximately 99,000(cut-off above 0.80 Au g/tonne) 191,900 ounces at the JebelJabal Guyan zone excluding other nearby prospects. The diamond drilling program continues at both the JebelJabal Guyan and Al Aqiq zones, testing depth and extension of mineralization with confirmed mineralization intersected at an additional 50100 meters depth beneath the Guyan zone.  A JORC compliant reserve update is currently being studied by Mining One (Australia).

Proven mineralized materials are those mineral deposits for which quantity is computed from dimensions revealed in outcrops, trenches, workings or drill holes, and grade is computed from results of detailed sampling. For ore deposits to be proven, the sites for inspection, sampling and measurement must be spaced so closely and the geologic character must be so well defined that the size, shape, depth and mineral content of reserves are well established. Probable mineralized materials are those for which quantity and grade are computed from information similar to that used for proven mineralized materials, but the sites for inspection, sampling and measurement are farther apart or are otherwise less adequately spaced. However, the degree of assurance, although lower than that for proven mineralized materials, must be high enough to assume continuity between points of observation.

The metallurgical studies conducted on the ore samples taken from the zones indicatedPlant performance thus far in 2020 indicates that 84.7%81% of the copper and 78.0%75% of the zinc could beis being recovered in the copper and zinc concentrates. Overall, gold and silver recovery from the ore was estimated to be 77.3%51.9% and 81.3%44.1%, respectively, partly into copper concentrate and partly as bullion through cyanide processing of zinc concentrates and mine tailings. Further studies recommended by consultants mayThe plant is continually conducting process optimizations to improve those recoveries and thus the potential profitability of the project; however, there can be no assurances of this effect.

Mineable (recoverable) reserves include:
·21%24% sidewall dilution in the stope production
·0.13Mt0.06Mt surface stockpiles

Mineable (recoverable) reserves exclude:
·Mining of any mineralization less than mineable width of 1.0m
·Sill Pillar (which was previously included). Technically, it is not mineable with current underground infrastructure and backfilling practices, so this pillar (0.6Mt) was excluded from Reserves
·All ofAny low grade (CuEq<1.01%) material (0.4Mt) which has to mined out and stored separately
Compared to 2019 MRE, the Moyeath orebody since it is categorized as Inferred

The updated reserves reflect a major1.32M tonnes increase to the MRE, as of August 2017. This increase is attributableJanuary 2020, due to a more realistic COG (cut-off grade)additional drilling at Saadah, Al Houra and additional geological data gathered since August 2017.Moyeath orebodies. The updated MRE (January 2018) also isdepth of the three orebodies are not tested yet and underground drilling will continue in line with2020 and the WGM (2009) Mineral Resources Estimate.coming years to extend the orebody at depth.

Access and all mine services already exist at the Moyeath orebody already exist. A new Decline from surface will intersect the top of the orebody within the next few weeks. Development ore mining on 1348 Level was completed in early

2019, and development mining on 1366 Level began in early 2020. During 2020, AMAK recently started core drilling here.estimates that approximately 100,000 tonnes will be mined out from Moyeath orebody. A drilling program of 8,000 meters (8 months) has been completed at Moyeath. MineMoyeath, which upgraded 1.86M tonnes (proven+probable) class. This will be included in the mine design and other modifying factors are planned to convertincorporated into the Moyeath orebody into Probable Reserves (mineable). Together with upgrading other orebodies (Saadah and Al Houra), the mine life could easily extend to +12 years.Life of Mine schedule. AMAK believes that Moyeath is the most attractive opportunity for an extended life and higher zinc metal recovery through the lifeLife of mine.

The metallurgical recoveries are assumed as 83% for copper and 72% for zinc after 2019. Both are on the conservative side given that historical recoveries were around 84% for copper and 76% for zinc. Currently a more sophisticated reagent suite is being tested at the plant to increase the recoveries another 1-2 % for both copper and zinc circuits: however, there can be no assurances of this effect.

The(1)Non-GAAP financial impact of Hurricane Harveymeasure. See the information under the heading "Non-GAAP Financial Measures" below for additional information about this measures and a reconciliation to our company was significant.  Harvey made landfall on the Texas Gulf Coast on August 25, 2017, and affected operations at both SHR and TC.  We estimate the total negative impact to 2017 EBITDA was approximately $1.5 million to $1.8 million.  This includes expenses related to generator rentals, overtime labor, and maintenance and repairs of approximately $0.7 million.  This estimate also includes lost sales due to outages at customer and supplier facilities.  Neither of our facilities suffered any significant damage.

Non-GAAP Financial Measures

We include in this Annual Report on Form 10-K the non-GAAP financial measures of EBITDA from continuing operations and Adjusted EBITDA and Adjusted Net Incomefrom continuing operations and provide reconciliations from our most directly comparable GAAP financial measuresmeasure to those measures.

We believe these financial measures provide users of our financial statements with supplemental information that may be useful in evaluating our operating performance. We also believe that such non–GAAP measures, when read in conjunction with our operating results presented under GAAP, can be used to better assess our performance from period to period and relative to performance of other companies in our industry, without regard to financing methods, historical cost basis or capital structure. These measures are not measures of financial performance or liquidity under GAAP and should be considered in addition to, and not as a substitute for, analysis of our results under GAAP.
EBITDA from continuing operations and Adjusted EBITDA from continuing operations: We define EBITDA from continuing operations as net income (loss) from continuing operations plus interest expense (benefit) including derivative gains and losses, income taxes, depreciation and amortization. We define Adjusted EBITDA from continuing operations as EBITDA from continuing operations plus share-basedshare–based compensation, plus restructuring and severance expenses, plus losses on extinguishment of debt, plus or minus equity in AMAK's earnings and losses, plus impairment losses, plus or minus gains from equity issuances,or losses on disposal of assets, and plus or minus gains or losses on acquisitions.  We define Adjusted Net Income as net income plus or minus tax effected equity in AMAK's earnings and losses or gains from equity issuances, plus or minus tax effected gains or losses on acquisitions, and plus or minus significant tax code
changes.  These measures are not measures of financial performance or liquidity under U.S. GAAP and should be considered in addition to, not as a substitute for, net income, nor as an indicator of cash flows reported in accordance with U.S. GAAP. These measures are used as supplemental financial measures by management and external users of our financial statements such as investors, banks, research analysts and others.  We believe that these non-GAAP measures are useful as they exclude transactions not related to our core cash operating activities.

The following table presents a reconciliation of net income (loss), our most directly comparable GAAP financial performance measure for each of the periods presented, to EBITDA from continuing operations and Adjusted EBITDA and Adjusted Net Income.from continuing operations.

Overview

Overview
The following discussion and analysis of our financial results, as well as the accompanying unaudited consolidated financial statements and related notes to consolidated financial statements to which they refer, are the responsibility of the management of the Company.our management. Our accounting and financial reporting fairly reflect our business model involvingwhich is based on the manufacturing and marketing of petrochemicalspecialty petrochemicals products and specialty waxes.  Our business model involves the manufacture and sale of tangible productswaxes and providing custom processingmanufacturing services.
Our consistentpreferred supplier position in the specialty petrochemicals market is derived from the combination of our reputation as a reliable supplier established over many years, the very high purity of our products, and a focused approach to providing high purity products and quality servicescustomer service. In specialty waxes, we are able to deliver to our customers has helpeda performance and price point that is unique to sustain our current position asmarket; while the diversity of our custom processing assets and capabilities offers solutions to our customers that we believe are uncommon along the U.S. Gulf Coast.
Enabling our success in these businesses is a preferred suppliercommitment to operational excellence which establishes a culture that prioritizes the safety of various petrochemical products.

our employees and communities in which we operate, the integrity of our assets and regulatory compliance. This commitment drives a change to an emphasis on forward-looking, leading-indicators of our results and proactive steps to continuously improve our performance. We bring the same commitment to excellence to our commercial activities where we focus on the value proposition to our customers while understanding opportunities to maximize our value capture through service and product differentiation, supply chain and operating cost efficiencies and diversified supply options. We believe over time our focus on execution, meeting the needs of our customers and the prudent control of our costs will create value for our stockholders.
Business Environment and Risk Assessment

We believe we are well-positioned to participate in the US chemical industry growth driven by new investments to grow the Company.and overall economic growth. While petrochemical prices are volatile on a short-term basis and depend on the demand of our customers' products, our investment decisions are based on our long-term business outlook using a disciplined approach in selecting and pursuing the most attractive investment opportunities.

PetrochemicalSpecialty Petrochemicals Operations

SHR's worldwide petrochemical demand increased during 2017specialty petrochemicals sales decreased in 2019 compared to 2016.   Petrochemical product2018. Product sales revenue increased 17.5%decreased 9.9% driven by volume decline of 5.4% and lower 2019 product prices compared to 2018 primarily by petrochemical volume growth of 9.1%.  Wedue to lower feedstock costs. During 2019 SHR continued to emphasize operational excellence and our competitive advantages achieved through our high quality products and outstanding customer service and responsiveness.

We also made major strides in improving plant reliability and safety.
During 20172019 feedstock pricescosts were about 15% higherapproximately 20% lower than 20162018 reflecting higherlower crude oil prices. During 2017, average feedstock price rose by $0.17 per gallon from 2016.  Fourth quarter 2017 feedstock prices were 7.2% or $0.09 per gallon higher compared to the fourth quarter of 2016.  About 60%Approximately 68% of our prime products are sold under formula pricing whereby feedstock costs are passed along to the customer typically with a one month lag. Thus, when feedstock prices start rising,falling, we experience lowerhigher margins as formula pricing lags feedstock costs. During 2017most of 2019 prime products margins declined as a result of greaterwere assisted due to falling feedstock costs and reduced competitive pricing pressure on prime products sales that are based on spot pricing not formula-basednon-formula pricing. Our by-product margins improved significantly compared to 2018 as SHR benefited from a full year of reliable operation of the Advanced Reformer unit which upgrades by-products to higher value products.
On October 29, 2019, a severe weather event at the Silsbee plant caused significant damage to one of the feedstock storage tanks. The damaged tank leaked hydrocarbon product into the tank containment area. Spill cleanup was completed promptly and the tank has been taken out of service. The total cost of the cleanup and lost product was approximately $2 million and will be substantially covered by insurance. Some insurance proceeds were received in December 2019 and we expect the remaining proceeds to be received in 2020.

Specialty WaxWaxes Operations

Sales revenues for our specialty waxes business decreased approximately 9.1% in 2019 from 2018 as we had lower wax product revenues and lower custom processing revenues. The decline in revenues was primarily due to operational issues at our Pasadena, Texas facility as well as wax feed supply constraints from our suppliers.
Most specialty wax markets are mature. Key applications for our specialty polyethylene waxes are in hot melt adhesives ("HMA"), plastic processing, PVC lubricants and inks, paints and coatings, where they act as surface or rheology modifiers. The HMA market is expected to grow at a higher rate than GDP growth due to growth in the developing markets and increases in packaging requirements due to changes in consumer purchasing (shift to home deliveries via the internet) in developed economies. Road marking paints are also expected to grow at rates exceeding GDP growth based upon an expectation that there will be infrastructure investment in the U. S.U.S. The PVC market is expected to grow at GDP rates; however, we expect to get more traction out of our products within this market with acceptance of our new PVC grade waxes. The global wax market is being impacted bybenefiting from the reduction of paraffin wax availability from large refiners as they move toward more hydrocracking and hydroisomerization to produce group III lube oils and distillate. Our wax sales volume increased 4%
Restructuring and Severance Impact
During 2018, the Company incurred restructuring and severance expenses of $2.3 million which were included in 2017 from 2016 while revenues increased 17%.




certain executives during 2018 as part of the restructuring of executive management and the reduction in the workforce at our Silsbee, Texas facility in December 2018. These expenses related to severance, stock compensation for continued vesting of time-vested shares issued under the Company's long-term incentive plan, and certain employee benefits including medical insurance and vacation. As of December 31, 2018, approximately $1.1 million had been incurred, and an additional liability of $1.2 million was accrued related to future benefits. As of December 31, 2019, there is less than $0.1 million remaining for accrued restructuring related liabilities.

Pursuant to the Fourth Amendment, total borrowings under the Term Loan Facility were increased to $87.5 million under a single combined term loan, which comprised new term loan borrowings together with approximately $60.4 million of previously outstanding term loans under the Term Loan Facility. The $60.4 million of previously outstanding term loans included the remaining outstanding balances on the Acquisition loan and the multiple advance term loan facility described above. Proceeds of the new borrowings under the Term Loan Facility were used to repay a portion of the outstanding borrowings under the Revolving Facility and pay fees and expenses of the transaction. As of December 31, 2019, we had $3 million in borrowings outstanding under the Revolving Facility and $80.9 million in borrowings outstanding under the Term Loan Facility. In addition, we had approximately $50 million of available borrowings under our Revolving Facility at December 31, 2019. However, TOCCO’s ability to make additional borrowings under the Revolving Credit Facility at December 31, 2019 was limited by, and in the future may be limited by our obligation to maintain compliance with the covenants contained in the ARC with terms which increased the MaximumAgreement (including maintenance of a maximum Consolidated Leverage Ratio financial covenant of 3.25x to 4.00x at March 31, 2017, and 4.25x at June 30, 2017, before stepping down to 3.75x at September 30, 2017, 3.50x at December 31, 2017, and reverting to the original financial covenant of 3.25x at March 31, 2018.

Gross Revenue

2016-2017

Revenues increasedGross revenue for the Specialty Petrochemicals segment decreased from 20162018 to 20172019 by approximately 15.6% due to an increase in sales volume of 9.1% and an increase in average selling price of 7.7% partially offset by a decrease in processing fees of 21.7%.

2015-2016

Revenues decreased from 2015 to 2016 by approximately 16.6%10.2% due to a decrease in specialty petrochemicals sales volume and a decrease in average selling prices. Decline in selling price was primarily attributable to lower feedstock costs in 2019 which impacts pricing for our formula customers.

The operation of 7.7%.  the Advanced Reformer unit results in some volumetric yield loss leading to lower volumes.
Our average selling price increased partlydecreased primarily because aof lower feedstock costs.

Average delivered feedstock price for 20172019 was 17.8% higher20.0% lower than 2016.2018 as Natural Gasoline prices fell with crude oil prices. The decrease in average selling price was also due to lower non-formula pricing for our prime products.

Petrochemical product sales decreased 18.4% from 2015 to 2016 due to a decrease in total sales volume of 12.1% and a decrease in average selling price of 7.2%.  Our average selling price decreased because a large portion of our sales are contracted with pricing formulas which are tied to prior month Natural Gas Liquid (NGL) prices which is our primary feedstock.  Our average selling prices for our non-formula priced customers alsoProcessing fee declined approximately 10.5%19.5% from 2018 to 2019 primarily due to competitive pressure on pricing.  Average delivered feedstock price for 2016 was 7.4% lower than 2015.  We also saw a significant decrease in our margin on byproduct sales from 2015 to 2016.  Prime product sales volume (total petrochemical product sales volume less byproduct sales volume) decreased 8.8% from 2015 to 2016 primarily due to lower demand in North America.  Margins on our petrochemical products were also negatively impacted by financial penalties that we incurred due to feedstock purchases below minimum amounts as prescribed by our agreement with suppliers.

Foreign sales volume accounted for approximately 22.7%the termination of volume and 26.3% of revenue for petrochemical product sales during 2016 as compared to 25.2% of volume and 27.9% of revenue during 2015.

Processing Fees

2016-2017

Processing fees decreased 21.7% from 2016 to 2017 primarily due to a reduction in fees associated with a customer who reimbursed us for installation expenses plus a markup.  We were successfulcontract in negotiating a contract extension with onethe fourth quarter of our processing customers whose contract was set to expire at the end of 2017.

2015-2016

Processing fees increased 51.1% from 2015 to 2016 primarily due to fees associated with a customer who reimbursed us for installation expenses plus a markup.

Cost of Sales increased 15.8%decreased 17.5% from 20162018 to 2017 primarily2019 due to lower raw material costs, lower operating expense and the increasedecrease in sales volume and higher raw material costs.volume. Our average delivered feedstock cost per gallon increased 17.8% over 2016 and volume processed increased 10.0%decreased approximately 20%. We useOur feedstock is natural gasoline. The market price for natural gasoline as feedstock whichdeclined 19% from 2018 to 2019 mostly tracking the decline in crude oil price. The price of natural gasoline is highly correlated with the price of crude oil. Natural gasoline is the heavier liquid component remaining after ethane, propane and butanes are
removed from liquids produced by natural gas wells. The material is a commodity product in the oil/petrochemical markets and generally is readily available.  The price of natural gasoline is correlated with the price of crude oil with an R-squared value of approximately 90%.  We expect our advanced reformer unit (Aromax® II) which is expected to start-up in the third quarter of 2018, will enable us to convert the less desirable components in our feed into higher value products, thereby allowing us to sell our byproducts at higher prices than are currently realized.

2015-2016

Cost of Sales decreased 11.7% from 2015 to 2016 primarily due to the decrease in sales volume.  Our average delivered feedstock cost per gallon decreased 7.4% over 2015 while volume processed decreased 10.9%.

Total Operating Expense(includes but is not limited to natural gas, operating labor, depreciation, and transportation)

2016-2017

Total Operating Expense increased 0.3%decreased 1.2% from 20162018 to 2017.  Natural gas,2019 or approximately $0.9 million. The key drivers for the decrease were operating labor and transportation are the largest individual expenses in this category; however, not all of these increased.

Natural gas expense increased 48.8% from 2016 to 2017 due tocosts, offset by an increase in the average per unit cost and volume consumed.  The average price per MMBTU for 2017 was $3.24 whereas, for 2016 the average per unit cost was $2.61.  Volume consumed increased to approximately 1,509,000 MMBTU from about 1,294,000 MMBTU.

Labor costs declined 3.0% from 2016 to 2017 despite a 3.8% increase in headcount from year end 2016 to year end 2017.  Approximately 19.9% of ourdepreciation. Operating labor costs were capitalized in 2017 due to the construction of the advanced reformer unit; whereas, in 2016 approximately 12.0% was capitalized.

Transportation costs were higher by 4.7%lower primarily due to the increasereorganization and workforce reduction at our Silsbee, Texas facility at the end of 2018 which reduced the workforce by approximately 20%. Transportation costs decreased primarily due to lower sales volume. Depreciation increased due to the commissioning of the Advanced Reformer unit in sales volume.

Natural gas expense decreased 21.2%approximately 15% from 20152018 to 20162019 due to a decrease in the average per unit cost and volume consumed. Consumption was lower than in 2018 primarily due to lower sales volume and efficiencies related to the Advanced Reformer unit. The average price per MMBTU for 20162019 was $2.61 whereas, for 2015 the average per unit cost was $2.94.  Volumedown approximately 12.5% from 2018 while volume consumed decreased to approximately 1,294,0001,633,000 MMBTU from about 1,402,000approximately 1,684,000 MMBTU.

Gross Margin
LaborGross margin increased from 10.4% of gross revenue in 2018 to 17.7% of gross revenue in 2019. This represents an increase of approximately 70%. The increase in gross margin was driven by an increase in margins for both prime products and by-products. Prime product margins benefited from lower feedstock costs while significant greater reliability of the Advanced Reformer unit contributed to an increase in by-product margins. Additionally, operating expenses declined 0.2% from 2015approximately 1.2% or nearly a million dollars thus also helping to 2016.  Profit sharing distributions were lower and employee headcount decreased approximately 2.7% from year end 2015increase gross margin in 2019 compared to year end 2016.

Transportation costs were lower by 2.8% primarily due to the decrease in sales volume.

The decline due to increasesdecreases in material cost, labor, freight, equipment maintenance, and natural gas utilities.  Material cost increased 51.2% primarilyutilities was partially offset by higher wax material costs. Labor decreased approximately 2.7% due to materialdecreased overtime. Maintenance costs associated with the on-purpose PEat our Pasadena facility decreased significantly compared to 2018. In 2018 we incurred maintenance expense to refurbish and repair a variety of equipment at B Plant. We benefited from more reliable B plant operation in 2019.
Gross Margin
Gross Margin for 2019 was (3.3)% of gross revenue compared to 5.1% of gross revenue in 2018. Gross margin was impacted by a 7.8% decline in wax sales we distributed into Latin America forvolume and a third party.  Labor increased approximately 22.4% due to increased overtime and the addition10.3% decline in processing revenues. This was only partially offset by a 1.5% decline in cost of personnel to operate the new hydrogenation/distillation unit when it came online in 2017.  Freight increased approximately 112.5% due tosales where lower operating expenses approximated the increase in shipments and a change in our shipping terms.  We now ship most products with destination terms.  Equipment maintenance increased 54.0% primarily due to the addition of B Plant and the introduction of new custom processing projects.  Natural gas utilities increased 71.6% due to an increase in the per unit cost and in volume consumed because of B Plant and the new hydrogenation/distillation unit.

2015-2016

Cost of Sales increased 34.9% from 2015 to 2016 due to increases in labor, freight, utilities and storage partially driven by the increased on-purpose polyethylene wax distributed in Latin America.  Labor increased approximately 16.3% due to increased overtime and addition of personnel to produce more product in B Plant and ensure we have personnel trained to operate the new hydrogenation/distillation project when it starts up in early 2017.  Freight increased approximately 79.1% due to the increase in shipments and a change in our shipping terms.  Utilities increased approximately 85.4% due to expenses associated with B plant.  Storage fees increased approximately 168.9% due to the increase in inventory which is stored offsite in third-party warehouses.  We were able to find an alternative storage location that is expected to reduce our storage fees in 2017.

Impairment of Goodwill and Certain Intangibles
We evaluated our goodwill for impairment during the fourth quarter of 2019 in connection with our annual review. As part of our review, in the fourth quarter we assessed 2019 operating performance and its impact on the operating cash flows of our Specialty Wax reporting unit. We completed our annual impairment test of goodwill in accordance with ASC 350-20 Goodwill. We concluded based on this analysis that the estimates of fair value of our Specialty Wax reporting unit was lower than its book value, including goodwill. As a result, we recorded a non-cash impairment charge of $21.8 million in the fourth quarter of 2019, representing all of the the goodwill previously allocated to this reporting unit. In connection with the additionimpairment analysis discussed above, we determined the indefinite-lived intangible assets were also impaired as of B Plant.

Depreciation and amortization increased 17.4%4% from 20162018 to 2017 primarily due to the addition of B Plant and the hydrogenation/distillation project coming online in 2017.

2015-2016

Depreciation and amortization decreased 14.1% from 2015 to 2016 primarily due to some of the assets which were near end of life at purchase becoming fully depreciated.  Most of the capital expenditures during 2016 were being recorded to construction in progress for which depreciation will begin when complete.

2015-2016

General corporate expenses decreased from 2015 to 2016 primarily due to a decrease in officer compensation because targets were not met; therefore, no executive bonuses were awarded.  This decrease of approximately $0.9 million was partially offset by increases in directors' fees, post-retirement benefits, and accounting and audit fees.  Directors' fees increased approximately $.03 million because of the addition of two directors and a restricted stock grant to directors.  Post-retirement benefits increased approximately $0.2 million due to an agreement with the former CEO to provide health benefits.  Accounting and audit fees increased approximately $0.1 million due to costs associated with our investmentInvestment in AMAK the retention of a new internal audit firm, and costs associated with B Plant valuation.

Equity in Losses of AMAK increased 188.1%9.4% from 20162018 to 20172019 due to a number of reasons as discussed below.

The mine operated on an improving basis throughout 2017 while operations were closed for almost all of 2016.  However, in 2017 because the mine was not operating at full capacity but was working toward that goal, costs increased.  Also, 2016 was positively affected by the settlementShipments decreased 32% from certain liabilities.  Metal prices were strong in 2017 with zinc prices hitting a ten year high during the year.   There were no unusual items in 2017.

Shipments increased 77% from 20162018 to 20172019 as indicated in the table below. AMAK volumes in dry metric tons (dmt) for 20172019 and 20162018 were as follows:

2015-2016

Equity in Losses of AMAK decreased from 2015 to 2016 primarily due to a settlement which was reached with the former operator of the AMAK mining facility.  During 2016 AMAK reached the settlement which included a reduction in previously accrued operating expenses of approximately $17.4 million.  We also recognized a gain on our investment in AMAK stemming from the July 2016 issuance of additional shares to Arab Mining Co.  The settlement, along with the gain, more than offset AMAK's 2016 operating losses (please see Note 11 to the consolidated financial statements for the impact on our statements).

In November 2015 the decision was made to temporarily close the mine and to terminate the contract with the operator.  This allowed AMAK to preserve asset value while the mill and underground assets were refurbished and equipment upgrades were installed.  Additionally in November 2015, AMAK received formal approval for new licenses that included an additional 151 square kilometers (km2) of territory close to AMAK's prior 44 km2 mine.  The additional territory comprised the Guyan and Qatan exploration licenses covering 151 km2, and within the Guyan exploration license, a 10 km2 mining lease which has potential for significant gold recovery.

Renovation and refurbishment work was completed and the mine began zinc and copper production in December 2016.  In addition, processing of the gold-bearing waste dumps from historical mining at the Guyan mining license area was initiated and limited amounts of gold produced.  An extensive exploration program for the rest of Guyan mining lease was initiated with some encouraging results: a JORC compliant Mineral Resource Estimate was completed in May 2017, with an additional 8,000 meters of drilling in the area expected in 2018.  A systematic program of infill drilling and exploration to extend the overall life of the copper and zinc mine begun in 2016 has resulted in updated Mineral Resource Estimates.  Drilling will continue to further enhance resources.

Since the mine was not operating during 2016, there were only two shipments of zinc during the first quarter of 2016 from inventory that was on hand at the end of 2015.  Approximately 16,000 dry metric tons were shipped.

The majority of our operating lease obligations are for railcars as discussed in Note 159 of the Notes to Consolidated Financial Statements. Purchase obligations are primarily related to commitments for our capital construction projects. The anticipated source of funds for payments due within three years that relate to contractual obligations is from a combination of continuing operations supplemented with borrowings under our credit facility.



Impact of Inflation

Our results of operations and financial condition are presented based on historical cost. While it is difficult to accurately measure the impact of inflation, we do not believe the overall effects of inflation, if any, on our results of operations and financial condition have been material.

New Accounting Standards Adopted in 2019

In May 2014February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 supersedes the revenue recognition requirements of FASB Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition and most industry-specific guidance throughout the Accounting Standards Codification, resulting in the creation of FASB ASC Topic 606, Revenue from Contracts with Customers. ASU 2014-09 requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. This ASU provides alternative methods of retrospective adoption and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company completed its assessment of the impact of the adoption of ASU 2014-09 across all revenue streams.  This included reviewing current accounting policies and practices to identify potential differences that would result from applying the requirements under the new standard.  We completed contract reviews and validated results of applying the new revenue guidance.  We adopted ASU 2014-09 on January 1, 2018, using the modified retrospective approach which will be fully presented in our Quarterly Report on Form 10-Q for the three months ended March 31, 2018.  Based on the completed analysis, we determined that the adjustment will not have a material impact on the consolidated financial statements.

In November 2015 the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The new standard eliminates the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The amendments are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company implemented ASU 2015-17 by classifying all of it deferred tax assets (liabilities) as noncurrent on the December 31, 2017 Balance Sheet, see Note 17.

In February 2016 the FASB issued ASU No. 2016-02, Leases (Topic 842),as amended by ASU 2017-13, 2018-01, 2018-10, 2018-11, and 2019-01, in order to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months)assets and lease liabilities on the balance sheet for those leases classified as a lease liabilityoperating leases under prior GAAP and a right-of-use asset (as defined).disclosing key information about leasing arrangements. The ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with earlier application permitted.   Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively usingrequires that a cumulative effect adjustment in the year of adoption.  The Company has several lease agreements for which the amendments will require the Company tolessee should recognize a lease liability to make lease payments (the lease liability) and a right-of-use asset which will representrepresenting its right to use the underlying asset for the lease term.term on the balance sheet. The Company is currently reviewingadopted ASC 842 in the amendmentsfirst quarter of 2019 utilizing the modified retrospective transition approach. The Company has elected (1) the package of practical expedients, which permits it not to ensure it is fully compliant byreassess under the new standard its prior conclusions about lease identification, lease classification, and initial direct costs for any existing leases as of the adoption date, and does not expect to early adopt.

In addition, the Company is anticipating electing an accounting policyelected the practical expedients related to (1) certain classes of underlying asset to not recognizeseparate non-lease components from lease components and (2) the short-term lease recognition exemption for all leases that qualify. The adoption of ASC 842 on January 1, 2019 resulted in the recognition of right-of-use assets of approximately $17.0 million and lease liabilities for operating leases of approximately $17.0 million on its Consolidated Balance Sheets, with a termno material impact to retained earnings or Consolidated Statements of twelve months or less. The Company is currently inOperations. See Note 9 to the processConsolidated Financial Statements for further information regarding the impact of fully evaluating the amendments and will subsequently implement new processes.  In addition, the Company will change its current accounting policies to comply with the amendments with such changes as mentioned above.

In March 2016 the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which will reduce complexity in accounting standards related to share-based payment transactions, including, among others, (1) accounting for income taxes, (2) classificationadoption of excess tax benefitsASC 842 on the statement of cash flow, (3) forfeitures, and (4) statutory tax withholding requirements.  The ASU is effective for annual reporting periods beginning on or after December 15, 2016, and interim periods within those annual periods.  The Company implemented the amendments as of January 1, 2017. The stock based compensation plan has not historically generated material amounts of excess tax benefits or deficiencies and, therefore, there is no material change

 in the Company's financial position or results of operation, as a result of adopting this Update. For additional information on the stock-based compensation plan, see Note 16.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350). The amendments in ASU 2017-04 simplify the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, under these amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss should not exceed the total amount of goodwill allocated to that reporting unit. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2019. Early adoption iswas permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The Company has goodwill from prior business combination and performs an annual impairment test or more frequently if changes or circumstances occur that would more-likely-than-not reduceelected to early adopt this ASU on January 1, 2019. See Note 10 to the fair valueConsolidated Financial Statements for a discussion of the reporting unit below its carrying value. During the year ended December 31, 2017, the Company performed its impairment assessment and determined the fair valueresults of the aggregated reporting units exceed the carrying value, such that the Company's goodwill was not considered impaired. Although the Company cannot anticipate futureour goodwill impairment assessments, based on the most recent assessment, it is unlikely that an impairment amount would need to be calculated and, therefore, the Company does not anticipate a material impact from these amendments to the Company's financial position and results of operations. The current accounting policies and processes are not anticipated to change, except for the elimination of the Step 2 analysis.testing.
In FebruaryJune 2018, the FASB issued ASU No. 2018-02, 2018-07, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive IncomeImprovements to Nonemployee Share-Based Payment Accounting. ASU 2018-02 was2018-07 simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-

based payments to employees, with certain exceptions. The Company adopted this ASU on January 1, 2019 and it did not have a material effect on the Company’s consolidated financial statements.
Recent Accounting Pronouncements
In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to address the income tax accounting treatmentDisclosure Requirements for Fair Value Measurement, which is designed to improve the effectiveness of disclosures by removing, modifying and adding disclosures related to fair value measurements. ASU No. 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, and the ASU allows for early adoption in any interim period after issuance of the stranded tax effectsupdate. The adoption of this ASU is not expected to have a significant impact on the Company’s consolidated financial statements.
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), to require the measurement of expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable forecasts and applies to all financial assets, including trade receivables. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. ASU No. 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within other comprehensive income due tothose fiscal years, and the prohibition of backward tracing due to an income tax rate change that was initially recorded in other comprehensive income due to the enactmentASU allows for early adoption as of the Tax Cuts and Jobs Act (TCJA) on December 22, 2017, which changed the Company's income tax rate from 35% to 21%. The amendments to the ASU changed US GAAP wherebybeginning of an entity may elect to reclassify the stranded tax effect from accumulated other comprehensive income to retained earnings. The amendments of the ASU may be adopted in totalinterim or in part using a full retrospective or modified retrospective method. The amendments of the ASU are effective for periodsannual reporting period beginning after December 15, 2018. EarlyThe Company is currently assessing the impact this ASU will have on its consolidated financial statements.
In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The amendments in this update simplify the accounting for income taxes by removing certain exceptions and clarifying certain requirements regarding franchise taxes, goodwill, consolidated tax expenses, and annual effective tax rate calculations. The ASU is effective for fiscal years beginning after December 15, 2020, and early adoption is permitted. The Company is currently assessing the effectimpact of this ASU 2018-02will have on its consolidated financial statements.

Consolidated Financial Statements.
Critical Accounting Policies

Our consolidated financial statements are based on the selection and application of significant accounting policies. The preparation of consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of net sales, expenses and allocated charges during the reported period. Actual results could differ from those estimates. However, we are not currently aware of any reasonably likely events or circumstances that would result in materially different results.

We believe the following accounting policies and estimates are critical to understanding the financial reporting risks present currently. These matters, and the judgments and uncertainties affecting them, are essential to understanding our reported results. See Note 2 to the Notes to the Consolidated Financial Statements for further information.

Discontinued Operations
Assets that are sold or classified as held for sale are classified as discontinued operations provided that the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results (e.g., a disposal of a major geographical area, a major line of business, a major equity method investment or other major parts of an entity).
Inventories

Finished products and feedstock are recorded at the lower of cost, determined on the first-in, first-out method (FIFO)("FIFO"); or market for SHR. For TC, inventory is recorded at the lower of cost or market as follows: (1) raw material cost is calculated using the weighted-average cost method and (2) product inventory cost is calculated using the specific cost method. See Note 8 to the Notes5 to the Consolidated Financial Statements for more information.

Revenue recognition
BeginningThe Company adopted FASB Accounting Standards Codification ("ASC") Topic 606 ("ASC 606"), Revenue from Contracts with Customers, and its amendmentswith a date of the initial application of January 1, 2017, due2018. As a result, the Company has changed its accounting policy for revenue recognition as detailed below. ASC 606 outlines a single comprehensive model for an entity to expansionuse in accounting for revenue arising from all contracts with customers, except where revenues are in scope of our plant assetsanother accounting standard. ASC 606 superseded the revenue recognition requirements in ASC Topic 605, "Revenue Recognition", and most industry specific guidance. ASC Topic 606 sets forth a five-step model for determining when and how revenue is recognized. Under the model, an entity is required to recognize revenue to depict the transfer of goods or services to a customer at SHRan amount reflecting the consideration it expects to receive in exchange for those goods and TC, we began inventorying spare partsservices. ASC 606 also requires certain additional revenue-related disclosures.
The Company applied the modified retrospective approach under ASC 606 which allows for the repair and maintenancecumulative effect of our plant, pipeline and equipment.adopting the new guidance on the date of initial application. Use of the modified retrospective approach means the Company's


comparative periods prior to initial application are not restated. The initial application was applied to all contracts at the date of the initial application.   The Company has determined that the adjustments using the modified retrospective approach did not have a material impact on the date of the initial application along with the disclosure of the effect on prior periods.
Accounting Policy
TableBeginning on January 1, 2018, revenue is measured based on a consideration specified in a contract with a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. In evaluating when a customer has control of Contentsthe asset we primarily consider whether the transfer of legal title and physical delivery has occurred, whether the customer has significant risks and rewards of ownership, and whether the customer has accepted delivery and a right to payment exists. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of product sales and processing. The Company does not offer material rights of return or service-type warranties.
39For 2017 the Company recognized revenue according to FASB ASC Topic 605 ("ASC 605"), "

Revenue recognition

Revenue is recorded whenRecognition", when: (1) the customer acceptsaccepted delivery of the product and title hashad been transferred or when the service iswas performed and we havethe Company had no significant obligations remaining to be performed; (2) a final understanding as to specific nature and terms of the agreed upon transaction hashad occurred; (3) price iswas fixed and determinable; and (4) collection iswas assured. For our productProduct sales generally met these criteria, are generally met, and revenue iswas recognized, when the product iswas delivered or title iswas transferred to the customer. Sales arerevenue was presented net of discounts, allowances, and sales taxes. Freight costs billed to customers arewere recorded as a component of revenue.  For our custom processing we recognize revenue when the service has been provided to the customer. Revenues received in advance of future sales of products or prior to the performance of services arewere presented as deferred revenues. Shipping and handling costs were classified as cost of product sales and processing and were expensed as incurred.
Nature of goods and services
The following is a description of principal activities – separated by reportable segments – from which the Company generates its revenue. For more detailed information about reportable segments, disaggregation of revenues, and contract balance disclosures, see Note 17.
Specialty Petrochemicals Segment
The Specialty Petrochemicals segment of the Company produces eight high purity hydrocarbons and other petroleum based products including isopentane, normal pentane, isohexane and hexane. These products are used in the production of polyethylene, packaging, polypropylene, expandable polystyrene, poly-iso/urethane foams, crude oil from the Canadian tar sands, and in the catalyst support industry. SHR's Specialty Petrochemicals products are typically transported to customers by rail car, tank truck, iso-container and ship.
Product Sales - The Company sells individual (distinct) products to its customers on a stand-alone basis (point-of-sale) without any further integration. There is no significant modification of any one or more products sold to fulfill another promised product or service within any of the Company's product sale transactions. The amount of consideration received for product sales is stated within the executed invoice with the customer. Payment is typically due and collected 30 to 60 days subsequent to point of sale.
Processing Fees - The Company's services consist of processing customer supplied feedstocks into custom products including, if requested, services for forming, packaging, and arranging shipping. Pursuant to tolling agreements the customer retains title to the feedstocks and processed products. The performance obligation in each tolling agreement transaction is the processing of customer provided feedstocks into custom products and is satisfied over time.   The amount of consideration received for product sales is stated within the executed invoice with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.
Specialty Waxes Segment
The Specialty Waxes segment of the Company manufactures and sells specialty polyethylene and poly alpha olefin waxes and also provides custom processing services for customers.
Product Sales - The Company sells individual (distinct) products to its customers on a stand-alone basis (point-of-sale) without any further integration. There is no significant modification of any one or more products sold to fulfill another promised product or service within any of the Company's product sale transactions. The amount of consideration received for product sales is stated within the executed invoice with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.

Processing Fees - The Company's promised services consist of processing customer supplied feedstocks into custom products including, if requested, services for forming, packaging, and arranging shipping. Pursuant to tolling agreements and purchase order arrangements, the customer typically retains title to the feedstocks and processed products. The performance obligation in each tolling agreement transaction and purchase order arrangement is the processing of customer provided feedstocks into custom products and is satisfied over time.   The amount of consideration received for product sales is stated within the executed invoice with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.
Long-lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable from estimated future undiscounted cash flows. If the estimated future undiscounted cash flows are less than the carrying value of the assets, we calculate the amount of impairment if the carrying value of the long-lived assets exceeds the fair value of the assets. Our long-lived assets include our petrochemicalspecialty petrochemicals facility and our specialty synthetic waxwaxes facility.

Our petrochemicalspecialty petrochemicals facility and specialty synthetic waxwaxes facility are currently our revenue generating assets. The facilities were in full operation at December 31, 2017.

2019.
Goodwill and other intangible assets

Goodwill and indefinite-lived intangible assets are tested for impairment at least annually; however, these tests are performed more frequently when events or changes in circumstances indicate that the asset may be impaired. Impairment exists when carrying value exceeds fair value.

Definite-lived intangible assets are being amortized using discounted estimated future cash flows over the term of the related agreements. We continually evaluate the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they will be removed from the consolidated balance sheets.

See Note 10 to the Notes to the Consolidated Financial Statements for additional information.

Investment in AMAK

(Held-for-Sale)
We account for our investment in AMAK using the equity method of accounting under which we record in income our share of AMAK's income or loss for each period. The amount recorded is also adjusted to reflect the amortization of certain differences between the basis in our investment in AMAK and our share of the net assets of AMAK as reflected in AMAK's financial statements. Any proceeds received from or payments made to AMAK are recorded as decreases or increases in the balance of our investment. See Note 11 to the Notes6 to the Consolidated Financial Statements.

We assess our investment in AMAK for impairment when events are identified, or there are changes in circumstances that may have an adverse effect on the fair value of the investment.  We consider recoverable ore reserves and the amount and timing of the cash flows to be generated by the production of those reserves, as well as, recent equity transactions within AMAK.  Factors which may affect carrying value include, but are not limited to, mineral prices, capital cost estimates, equity transactions, the estimated operating costs of any mines and related processing, ore grade and related metallurgical characteristics, the design of any mines and the timing of any mineral production. There are no assurances that we will not be required to take a material write-down of any of our mineral properties.

Environmental Liabilities

Our operations are subject to the rules and regulations of the TCEQ which inspects the facilities at various times for possible violations relating to air, water and industrial solid waste requirements. As noted in Item 1. Business,, evidence of groundwater contamination was discovered at SHR in 1993. The recovery process, initiated in 1998, is proceeding as planned and is expected to continue for many years. See Note 15 to the Notes14 to the Consolidated Financial Statements.

Share-Based Compensation

We expense the cost of director and employee services received in exchange for an award of equity instruments based on the grant date fair value of such instruments. For options we use the Black-Sholes model to calculate the fair value of the equity instrument on the grant date. See Note 16 to the Notes15 to the Consolidated Financial Statements.

Off Balance Sheet Arrangements

Off balance sheet arrangements as defined by the SEC means any transaction, agreement or other contractual arrangement to which an entity unconsolidated with the registrant is a party, under which the registrant has (i) obligations under certain guarantees or contracts, (ii) retained or contingent interest in assets transferred to an unconsolidated entity or similar arrangements, (iii) obligations under certain derivative arrangements, and (iv) obligations arising out of a material variable interest in an unconsolidated entity. Our guarantee for AMAK's debt is considered an off balance sheet arrangement. Please see further discussion under the heading "Investment in AMAK" in Item 1. Business.

Income Taxes

In determining our income tax provision, we assess the likelihood our deferred tax assets will be recovered through future taxable income. Based on this assessment, a valuation allowance against all or a portion of our deferred tax asset that will, more likely than not, be realized. If these estimates, assumptions, or actual results of operations change in the future, we may reverse the valuation allowance against deferred tax assets. Income tax liabilities are determined based on judgment and estimates assuming it is more likely than not that the position will be sustained upon examination by a taxing authority. See Note 17 to the Notes16 to the Consolidated Financial Statements.

On December 22, 2017, Public Law No. 115-97, also known as, the Tax Cuts and Jobs Act (TCJA)("TCJA") was enacted. The TCJA includesincluded a number of changes to existing U.S. tax laws that impactimpacted the Company, most notably a reduction of the U.S. federal corporate income tax rate from a maximum of 35 percent35% to a flat 21 percent21% for tax years effective January 1, 2018. The TCJA also implementsimplemented a territorial tax system, providesprovided for a one-time deemed repatriation tax on unrepatriated foreign earnings, eliminateseliminated the alternative minimum tax (AMT)("AMT"), makesmaking AMT credit carryforwards refundable, and permits the acceleration of depreciation for certain assets placed into service after September 27, 2017. In addition the TJCA createscreated prospective changes beginning in 2018, including repeal of the domestic manufacturing deduction, acceleration of tax revenue recognition, capitalization of research and development expenditures, additional limitations on executive compensation and limitations on the deductibility of interest.

The Company has elected to recognize the income tax effects of the TCJA in its financial statements in accordance with Staff Accounting Bulletin 118 (SAB 118), which provides guidance for the application of ASC Topic 740 Income Taxes, in the reporting period in which the TCJA was signed into law. Under SAB 118 when a Company does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the TCJA it will recognize provisional amounts if a reasonable estimate can be made. IfAfter the analysis, the Company did not identify any items for which the income tax effects of the TCJA have not been completed and a reasonable estimate cannotcould not be made then no impact is recognized for the effectdetermined as of the TCJA. SAB 118 permits an up to one year measurement period to finalize the measurement of the impact of the TCJA.

December 31, 2019.
The changes to existing U.S. tax laws as a result of the TCJA, which will have the most significant impact on the Company's federal income taxes are as follows:

Reduction of the U.S. Corporate Income Tax Rate - The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the TCJA, the Company revalued its ending net deferred tax liabilities at December 31, 2017. The reduction in the corporate income tax rate resulted in the Company recording $10.3 million benefit from deferred taxes.taxes in the year ending December 31, 2017.

Acceleration of Depreciation - The Company recognized a provisional reduction to net deferred tax assets attributable to the accelerated depreciation for certain assets placed into service after September 27, 2017. This provisional adjustment resulted in an increase in income tax receivable of approximately $961,000.

Derivative Instruments

We periodically use financial commodity agreements to hedge the cost of natural gasoline, the primary source of feedstock, and natural gas used as fuel to operate our plant to manage risks generally associated with price volatility.  The commodity agreements are recorded in our consolidated balance sheets as either an asset or liability measured at fair value. Our commodity agreements are not designated as hedges; therefore, all changes in estimated fair value are recognized in cost of petrochemical product sales and processing$961,000 in the consolidated statements of income. Atyear ending December 31, 2017, we had no financial commodity agreements in place.2017.

On March 21, 2008, SHR entered into a pay-fixed, receive-variable interest rate swap agreement with Bank of America related to the $10.0 million term loan secured by plant, pipeline and equipment. The effective date of the interest rate swap agreement was August 15, 2008, and was terminated on December 15, 2017.  We received credit for payments of variable rate interest made on the term loan at the loan's variable rates, which are based upon the London InterBank Offered Rate (LIBOR), and paid Bank of America an interest rate of 5.83% less the credit on the interest rate swap.  We had originally designated the interest rate swap as a cash flow hedge under ASC Topic 815 (see Note 22); however, due to the new debt agreements associated with the Acquisition in 2014, we believed that the hedge was no longer entirely effective.  Due to the time required to make the determination and the immateriality of the hedge, we began treating the interest rate swap as ineffective as of October 1, 2014.  The fair value of the derivative liability associated with the interest rate swap at December 31, 2017, and 2016 totaled $0.0 million and $0.1 million, respectively.

We assessed the fair value of the interest rate swap using a present value model that includes quoted LIBOR rates and the nonperformance risk of the Company and Bank of America based on the Credit Default Swap Market (Level 2 of fair value hierarchy).  See Notes 5 and 22 to the Notes to the Consolidated Financial Statements.

ItemITEM 7A. Quantitative and Qualitative Disclosures about Market Risk.

The market risk inherent in our financial instruments represents the potential loss resulting from adverse changes in interest rates, foreign currency rates and commodity prices. Our exposure to interest rate changes results from our variable rate debt instruments which are vulnerable to changes in short term United States prime interest rates. At December 31, 2017, 20162019, 2018 and 2015,2017, we had approximately $99.6$83.9 million, $84.0$103.3 million and $82.3$99.6 million, respectively, in variable rate debt outstanding, excluding deferred financing costs. A hypothetical 10% change in interest rates underlying these borrowings would result in annual changes in our earnings and cash flows of approximately $405,000, $275,000$383,000, $433,000 and $199,000$405,000 at December 31, 2019, 2018 and 2017, 2016 and 2015, respectively.

We do not view exchange rates exposure as significant and have not acquired or issued any foreign currency derivative financial instruments.

We purchase all of our raw materials, consisting of feedstock and natural gas, on the open market. The cost of these materials is a function of spotnon-formula market oil and gas prices. As a result, our revenues and gross margins could be affected by changes in the price and availability of feedstock and natural gas. As market conditions dictate, from time to time we engage in various hedging techniques including financial swap and option agreements. We do not use such financial instruments for trading purposes and are not a party to any leveraged derivatives. Our policy on such hedges is to buy positions as opportunities present themselves in the market and to hold such positions until maturity, thereby offsetting the physical purchase and price of the materials.

At the end of 2017,2019, market risk for 20182020 was estimated as a hypothetical 10% increase in the cost of natural gas and feedstock over the market price prevailing on December 31, 2017.2019. Assuming that 20182020 total petrochemicalspecialty petrochemicals product sales volumes stay at the same rate as 2017,2019, the 10% market risk increase will result in an increase in the cost of natural gas and feedstock of approximately $13.7$12.5 million in fiscal 2018.2020.

ItemITEM 9A. Controls and Procedures.

(a)Disclosure Controls and Procedures.

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e)) under the Securities Exchange Act of 1934, as amended ("Exchange Act") that are designed to provide reasonable assurance that the information that we are required to disclose in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and such information is accumulated and communicated to our management, including our Chief Executive Office and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. It should be noted that because of inherent limitations, our disclosure controls and procedures, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objective of the disclosure controls and procedures are met.
As required by paragraph (b) of Rules 13a-15 and 15d-15 under the Exchange Act, our Chief Executive Officer, and Chief Financial Officer have evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded, as of the end of the period covered by this report, that our disclosure controls and procedures were effective at a reasonable assurance level to ensure that the information that we are required to disclose in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure because of the material weakness in our internal control over financial reporting described below.below.

(b)Management's Annual Report on Internal Control over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process that is designed under the supervision of our Chief Executive Officer and Chief Financial Officer, and effected by our Board of Directors, management and other personnel, to provide assurance regarding financial reporting and the preparation of the financial statements for external purposes in accordance with accounting principles generally accepted in the United States. Our internal control of financial reporting includes those policies and procedures that:
·Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;
·Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States, and that receipts and expenditures recorded by us are being made only in accordance with authorizations of our management and Board of Directors; and
·Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.
Internal control over financial reporting has inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material misstatements will not be prevented or detected on a timely basis by internal control over financial reporting. However, these inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce, though not eliminate, this risk. 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 and procedures may deteriorate.

Management has conducted its evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2017,2019, based upon the framework in Internal Control – Integrated Framework (2013) by the Committee of Sponsoring Organizations of the Treadway Commission.  Management's assessment included an evaluation of the design of our internal control over financial reporting and testing the operating effectiveness of our internal control over financial reporting.  Management reviewed the results of the assessment with the Audit Committee of the Board of Directors.  Based on

its assessment and review with the Audit Committee, management concluded that our internal control over financial reporting was effective as of December 31, 2017.2019.
(c)Attestation Report of the Registered Public Accounting Firm.

BKM Sowan Horan, LLP, an independent registered public accounting firm, has audited the consolidated financial statements included in this Annual Report on Form 10-K and, as part of their audit, has issued their report, included herein, on the effectiveness of our internal control over financial reporting.

(d) Remediation of Material Weakness in Internal Control Over Financial Reporting.

During the year ended December 31, 2016, management identified certain errors in the accounting for our investment in AMAK.  To remediate the material weakness, during 2017, we designed and implemented a comprehensive remediation plan to remediate the material weakness and generally strengthen our internal control over financial reporting.  During the fourth quarter of 2017, we successfully completed the testing necessary to conclude that the controls were operating effectively and have concluded that the material weakness has been remediated.

(e) Changes in Internal Control over Financial Reporting.

There have been no changes in our internal control over financial reporting during the fourth quarter of 20172019 that have materially affected, or are reasonable likely to materially affect, our internal control over financial reporting. From time to time, we make changes to our internal control over financial reporting that are intended to enhance its effectiveness and which do not have a material effect on our overall internal control over financial reporting.

To the Board of Directors and
Stockholders
of Trecora Resources

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Trecora Resources and Subsidiaries (the Company) as of December 31, 20172019 and 2016,2018, and the related consolidated statements of income, comprehensive income, stockholders'operations, stockholders’ equity and cash flows for each of the years in the three-yearthree–year period ended December 31, 20172019 and the related notes and schedules listed in the index at Item 15(a) (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20172019 and 2016,2018, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017,2019, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company'sCompany’s internal control over financial reporting as of December 31, 2017,2019, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 12, 2018,13, 2020, expressed an unqualified opinion.

Basis for Opinion

These financial statements are the responsibility of the Company'sCompany’s management. Our responsibility is to express an opinion on the Company'sCompany’s financial statements based on our audits. We are a public accounting firm registered with the 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 PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

NOTE 1 - BUSINESS AND OPERATIONS OF THE COMPANY

Trecora Resources formerly Arabian American Development Company, (the "Company") was organized as a Delaware corporation in 1967. The Company's principal business activities are the manufacturing of various specialty petrochemicalpetrochemicals products, specialty waxes and providing custom processing services.  The Company owns 33% of a Saudi Arabian joint stock company, Al Masane Al Kobra Mining Company ("AMAK") (see Note 11) and approximately 55% of the capital stock of a Nevada mining company, Pioche Ely Valley Mines, Inc. ("PEVM"), which does not conduct any substantial business activity but owns undeveloped properties in the United States.

The Company's petrochemicalspecialty petrochemicals operations are primarily conducted through a wholly-owned subsidiary, Texas Oil and Chemical Co. II, Inc. ("TOCCO"). TOCCO owns all of the capital stock of South Hampton Resources, Inc. ("SHR") and Trecora Chemical, Inc. ("TC"). SHR owns all of the capital stock of Gulf State Pipe Line Company, Inc. ("GSPL"). SHR owns and operates a specialty petrochemicalpetrochemicals product facility nearin Silsbee, Texas which manufactures high purity hydrocarbons used primarily in polyethylene, packaging, polypropylene, expandable polystyrene, poly-iso/urethane foams, Canadian tar sands, and in the catalyst support industry. TC owns and operates a facility located in Pasadena, Texas which manufactures specialty waxes and provides custom processing services. These specialty waxes are used in the production of coatings, hot melt adhesives and lubricants. GSPL owns and operates pipelines that connect the SHR facility to a natural gas line, to SHR's truck and rail loading terminal and to a major petroleum pipeline owned by an unaffiliated third party.

The Company owns 33% of a Saudi Arabian joint stock company, Al Masane Al Kobra Mining Company ("AMAK") (see Note 10) and approximately 55% of the capital stock of a Nevada mining company, Pioche Ely Valley Mines, Inc. ("PEVM"), which does not conduct any substantial business activity but owns undeveloped properties in the United States.
On October 2, 2019, we announced that we had entered into a Share Sale and Purchase Agreement (as amended, the “Purchase Agreement”) pursuant to which we have agreed to sell our entire investment in AMAK. The share sale is expected to close on or before March 31, 2020, subject to receipt of certain governmental approvals and other customary closing conditions. AMAK's historical financial results for the periods presented are reflected in our consolidated financial statements as discontinued operations. For further details, refer to Note 6 to the Consolidated Financial Statements.
We attribute revenues to countries based upon the origination of the transaction. All of our revenues for the years ended December 31, 2017, 2016,2019, 2018, and 2015,2017, originated in the United States. In addition, all of our long-lived assets are in the United States.

For convenience in this report, the terms "Company", "our", "us" or "we" may be used to refer to Trecora Resources and its subsidiaries.

Certain reclassifications have been made to the Consolidated Balance Sheet for the year ended December 31, 2016, related to our adoption of Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") 2015-17 as noted below and in Note 2.

The impact of the adoption ASU 2015-17 on the Company's previously issued December 31, 2016, balance sheet is as follows:

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation– The consolidated financial statements include the balance sheets, statements of income,operations, stockholders' equity, and cash flows of the Company, TOCCO, TC, SHR, GSPL and PEVM. Other entities which are not controlled but over which the Company has the ability to exercise significant influence such as AMAK, are accounted for using the equity method of accounting. All intercompany profits, transactions and balances have been eliminated.

Cash, Cash Equivalents and Short-Term Investments - Our principal banking and short-term investing activities are with local and national financial institutions. Short-term investments with an original maturity of three months or less are classified as cash equivalents.

Inventories - Finished products and feedstock are recorded at the lower of cost, determined on the last-in, first-out method (LIFO) at December 31, 2016, and first-in, first-out method (FIFO) at December 31, 2017;, or market for SHR. For TC, inventory is recorded at the lower of cost or market as follows: (1) raw material cost is calculated using the weighted-average cost method and (2) product inventory cost is calculated using the specific cost method.

Trade Receivables and Allowance for Doubtful Accounts – We evaluate the collectability of our trade receivables and adequacy of the allowance for doubtful accounts based upon historical experience and any specific customer financial difficulties of which we become aware. For the year ended December 31, 2016,2019, we decreased the balance by $23,000 due to collections of previously allowed for receivables. For the year ended December 31, 2018, we increased the balance by $90,000$152,000 due to an increase in sales in countries where there isconcerns regarding collectability for a greater risk of default and limited recourse should this occur.specific customer. For the yearsyear ended December 31, 2017, and 2015, the allowance balance was not increased.adjusted. We track customer balances and past due amounts to determine if customers may be having financial difficulties. This, along with historical experience and a working knowledge of each customer, helps determine accounts that should be written off. During 2016 we wrote off one account for approximately $93,000.  No amounts were written off in 20172019, 2018 or 2015.2017.
Discontinued Operations – Assets that are sold or classified as held for sale are classified as discontinued operations provided that the disposal represents a strategic shift that has (or will have) a major effect on our operations and financial results (e.g., a disposal of a major geographical area, a major line of business, a major equity method investment or other major parts of an entity).

Notes Receivable – We periodically make changes in or expand our custom processing units at the request of the customer. The cost to make these changes is shared by the customer. Upon completion of a project a non-interest note receivable is recorded with an imputed interest rate. Interest rate used onThere were no notes receivable outstanding notes duringas of December 31, 2017, and 2016, was 4%.2019 or 2018. The unearned interest iswas reflected as a discount against the note balance. The Company evaluates the collectability of notes based upon a working knowledge of the customer. The notes are receivable from custom processing customers with whom we maintain a close relationship.  Thus, all amounts due under the notes receivable are considered collectible, and no allowance was recorded at December 31, 2017 and 2016.

Plant, Pipeline and Equipment - Plant, pipeline and equipment are stated at cost. Depreciation is provided over the estimated service lives using the straight-line method. Gains and losses from disposition are included in operations in the period incurred. Maintenance and repairs are expensed as incurred. Major renewals and improvements are capitalized.

Interest costs incurred to finance expenditures during construction phase are capitalized as part of the historical cost of constructing the assets. Construction commences with the development of the design and ends when the assets are ready for use. Capitalized interest costs are included in plant, pipeline and equipment and are depreciated over the service life of the related assets.

Labor costs incurred to self-construct assets are capitalized as part of the historical cost the assets. Construction commences with the development of the design and ends when the assets are ready for use. Capitalized labor costs are included in plant, pipeline and equipment and are depreciated over the service life of the related assets.

Platinum catalyst is included in plant, pipeline and equipment at cost. Amortization of the catalyst is based upon cost less estimated salvage value of the catalyst using the straight line method over the estimated useful life (see Note 9)8).

Goodwill and Other Intangible Assets – Goodwill represents the future economic benefits arising from other assets acquired in the acquisition of TC that are not individually identified and separately recognized. Goodwill and indefinite-lived intangible assets are tested for impairment at least annually; however, these tests are performed more frequently when events or changes in circumstances indicate that the asset may be impaired. Impairment exists when carrying value exceeds fair value. Estimates of fair value are based on appraisals, market prices for comparable assets, or internal estimates of future net cash flows.

Definite-lived intangible assets consist of customer relationships, licenses, permits and developed technology that were acquired as part of the Acquisitionacquisition of TC. The majority of these assets are being amortized using discounted estimated future cash flows over the term of the related agreements. Intangible assets associated with customer
relationships are being amortized using the discounted estimated future cash flows method based upon assumed rates of annual customer attrition. We continually evaluate the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they will be removed from the consolidated balance sheets.

Business Combinations and Related Business Acquisition Costs– Assets and liabilities associated with business acquisitions are recorded at fair value using the acquisition method of accounting. We allocate the purchase price of acquisitions based upon the fair value of each component which may be derived from various observable and unobservable inputs and assumptions. We may use third-party valuation specialists to assist us in this allocation. Initial purchase price allocations are preliminary and subject to revision within the measurement period, not to exceed one year from the date of acquisition. The fair value of property, plant and equipment and intangible assets are based upon the discounted cash flow method that involves inputs that are not observable in the market (Level 3). Goodwill assigned represents the amount of consideration transferred in excess of the fair value assigned to identifiable assets acquired and liabilities assumed.

Business acquisition costs are expensed as incurred and are reported as general and administrative expenses in the consolidated statements of income. We define these costs to include finder's fees, advisory, legal, accounting, valuation, and other professional consulting fees, as well as, travel associated with the evaluation and effort to acquire specific businesses.

Investment in AMAK – We account for our investment in AMAK using the equity method of accounting under which we record in income our share of AMAK's income or loss for each period. The amount recorded is also adjusted to reflect the amortization of certain differences between the basis in our investment in AMAK and our share of the net assets of AMAK as reflected in AMAK's financial statements (see Note 11)6).

Any proceeds received from or payments made to AMAK are recorded as decreases or increases in the balance of our investment.
We assess our investment in AMAK for impairment when events are identified, or there are changes in circumstances that may have an adverse effect on the fair value of the investment. WeIn making our assessment we consider operating results, recoverable ore reserves, changes in commodity prices, and the amount and timing of the cash flows to be generated by the production of those reserves, as well as, recent equity transactions within AMAK.

mineral prices.
Other Assets - Other assets include a license used in petrochemicalspecialty petrochemicals operations, spare parts inventory, insurance receivables and certain petrochemicalspecialty petrochemicals assets. Beginning January 1, 2017, due to the expansion of our plant assets at SHR and TC, we began inventorying spare parts for the repair and maintenance of our plant, pipeline and equipment. Spare parts are accounted for on the first-in, first-out method (FIFO).using FIFO.

Long-Lived Assets Impairment - Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable based on the undiscounted net cash flows to be generated from the asset's use. The amount of the impairment loss to be recorded is calculated by the excess of the asset's carrying value over its fair value. Fair value is generally determined using a discounted cash flow analysis although other factors including the state of the economy are considered.

Revenue Recognition The Company adopted Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 606 ("ASC 606"), Revenue from Contracts with Customers, and its amendmentswith a date of the initial application of January 1, 2018. As a result, the Company has changed its accounting policy for revenue recognition as detailed below. ASC 606 outlines a single comprehensive model for an entity to use in accounting for revenue arising from all contracts with customers, except where revenues are in scope of another accounting standard. ASC 606 superseded the revenue recognition requirements in ASC Topic 605, "Revenue Recognition", and most industry specific guidance. ASC Topic 606 sets forth a five-step model for determining when and how revenue is recordedrecognized. Under the model, an entity is required to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods and services. ASC 606 also requires certain additional revenue-related disclosures.
The Company applied the modified retrospective approach under ASC 606 which allows for the cumulative effect of adopting the new guidance on the date of initial application. Use of the modified retrospective approach means the Company's comparative periods prior to initial application are not restated. The initial application was applied to all contracts at the date of the initial application.   The Company has determined that the adjustments using the modified retrospective approach did not have a material impact on the date of the initial application along with the disclosure of the effect on prior periods.

Accounting Policy

Beginning on January 1, 2018, revenue is measured based on a consideration specified in a contract with a customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. In evaluating when a customer has control of the asset we primarily consider whether the transfer of legal title and physical delivery has occurred, whether the customer has significant risks and rewards of ownership, and whether the customer has accepted delivery and a right to payment exists. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of product sales and processing. The Company does not offer material rights of return or service-type warranties.
For the year ended December 31, 2017 the Company recognized revenue according to FASB ASC Topic 605 ("ASC 605"), "Revenue Recognition", when: (1) the customer acceptsaccepted delivery of the product and title hashad been transferred or when the service iswas performed and we havethe Company had no significant obligations remaining to be performed; (2) a final understanding as to specific nature and terms of the agreed upon transaction hashad occurred; (3) price iswas fixed and determinable; and (4) collection iswas assured. For our productProduct sales generally met these criteria, are generally met, and revenue iswas recognized, when the product iswas delivered or title iswas transferred to the customer. Sales arerevenue was presented net of discounts, allowances, and sales taxes. Freight costs billed to customers arewere recorded as a component of revenue. For our custom processing we recognize revenue when the service has been provided to the customer.

Revenues received in advance of future sales of products or prior to the performance of services arewere presented as deferred revenues. Shipping and handling costs were classified as cost of product sales and processing and were expensed as incurred.
Nature of goods and services

The following is a description of principal activities – separated by reportable segments – from which the Company generates its revenue. For more detailed information about reportable segments, disaggregation of revenues, and contract balance disclosures, see Note 17.

Specialty Petrochemicals segment
The specialty petrochemicals segment of the Company produces eight high purity hydrocarbons and other petroleum based products including isopentane, normal pentane, isohexane and hexane. These products are used in the production of polyethylene, packaging, polypropylene, expandable polystyrene, poly-iso/urethane foams, crude oil from the Canadian tar sands, and in the catalyst support industry. SHR's specialty petrochemicals products are typically transported to customers by rail car, tank truck, iso-container and ship.
Product Sales – The Company sells individual (distinct) products to its customers on a stand-alone basis (point-of-sale) without any further integration. There is no significant modification of any one or more products sold to fulfill another

promised product or service within any of the Company's product sale transactions. The amount of consideration received for product sales is stated within the executed invoice with the customer. Payment is typically due and collected 30 to 60 days subsequent to point of sale.
Processing Fees – The Company's services consist of processing customer supplied feedstocks into custom products including, if requested, services for forming, packaging, and arranging shipping. Pursuant to Tolling Agreements the customer retains title to the feedstocks and processed products. The performance obligation in each Tolling Agreement transaction is the processing of customer provided feedstocks into custom products and is satisfied over time.   The amount of consideration received for product sales is stated within the executed invoice with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.
Specialty Waxes segment
The specialty waxes segment of the Company manufactures and sells specialty polyethylene and poly alpha olefin waxes and also provides custom processing services for customers.
Product Sales – The Company sells individual (distinct) products to its customers on a stand-alone basis (point-of-sale) without any further integration. There is no significant modification of any one or more products sold to fulfill another promised product or service within any of the Company's product sale transactions. The amount of consideration received for product sales is stated within the executed invoice with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.
Processing Fees – The Company's promised services consist of processing customer supplied feedstocks into custom products including, if requested, services for forming, packaging, and arranging shipping. Pursuant to Tolling Agreements and Purchase Order Arrangements, the customer typically retains title to the feedstocks and processed products. The performance obligation in each Tolling Agreement transaction and Purchase Order Arrangement is the processing of customer provided feedstocks into custom products and is satisfied over time. The amount of consideration received for product sales is stated within the executed invoice with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.
Shipping and Handling Costs - Shipping and handling costs are classified as cost of product sales and processing and are expensed as incurred.

Retirement Plan– We offer employees the benefit of participating in a 401(k) plan. We match 100% up to 6% of pay with vesting occurring over 2 years. For years ended December 31, 2017, 2016,2019, 2018, and 2015,2017, matching contributions of approximately $1,412,000, $1,195,000,$1,321,000, $1,502,000, and $1,116,000,$1,412,000, respectively, were made on behalf of employees.

Environmental Liabilities - Remediation costs are accrued based on estimates of known environmental remediation exposure. Ongoing environmental compliance costs, including maintenance and monitoring costs, are expensed as incurred.

Other Liabilities – We periodically make changes in or expand our custom processing units at the request of the customer. The cost to make these changes is shared by the customer. Upon completion of a project a note receivable and a deferred liability are recorded to recover the project costs which are then capitalized. At times instead of a note receivable being established, the customer pays an upfront cost. The amortization of other liabilities is recorded as a reduction to depreciation expense over the life of the contract with the customer. As of December 31 of each year, depreciation expense was offset and reduced by approximately $0.8 million, for 2017, $1.0$0.8 million, and $0.8 million, for 2016,2019, 2018, and $1.0 million for 2015.

2017, respectively.
Net Income Per Share - We compute basic income per common share based on the weighted-average number of common shares outstanding. Diluted income per common share is computed based on the weighted-average number of common shares outstanding plus the number of additional common shares that would have been outstanding if potential dilutive common shares, consisting of stock options, unvested restricted stock units, and shares which could be issued upon conversion of debt, had been issued (see Note 19)18).

Foreign Currency - The functional currency for the Company and each of the Company's subsidiaries is the US dollar (USD). Transaction gains or losses as a result of transactions denominated and settled in currencies other than the USD are reflected in the statements of income as foreign exchange transaction gains or losses. We do not employ any practices to minimize foreign currency risks. The functional and reporting currency of AMAK is the Saudi Riyal (SR). In June 1986 the SR was officially pegged to the USD at a fixed exchange rate of 1 USD to 3.75 SR; therefore, we translate SR into our reporting currency of the USD for income statement and balance sheet purposes using the fixed exchange rate. As of December 31, 2017, 20162019, 2018 and 2015,2017, foreign currency translation adjustments were not significant.

Management Estimates - The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts 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 during the reporting periods. Significant estimates

include allowance for doubtful accounts receivable and inventory obsolescence; assessment of impairment of our long-lived assets, goodwill, intangible assets and investments, financial contracts, litigation liabilities, post-retirement benefit obligations, guarantee obligations, environmental liabilities, income taxes and deferred tax valuation allowances. Actual results could differ from these estimates.

Share-Based Compensation – We recognize share-based compensation of stock options granted based upon the fair value of options on the grant date using the Black-Scholes pricing model (see Note 16)15). Share-based compensation expense recognized during the period is based on the fair value of the portion of share-based payments awards that is ultimately expected to vest. Share-based compensation expense recognized in the consolidated statements of incomeoperations for the years ended December 31, 2017, 2016,2019, 2018, and 20152017 includes compensation expense based on the estimated grant date fair value for awards that are ultimately expected to vest, and accordingly has been reduced for estimated forfeitures. Estimated forfeitures at the time of grant are revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Guarantees –We may enter into agreements which contain features that meet the definition of a guarantee under FASB ASC 460 "Guarantees" (see Note 15)14). These arrangements create two types of obligations:

a)We have a non-contingent and immediate obligation to stand ready to make payments if certain future triggering events occur. For certain guarantees, a liability is recognized for the stand ready obligation at the inception of the guarantee; and

b)We have an obligation to make future payments if those certain future triggering events do occur. A liability for the payment under the guarantee is recognized when 1) it becomes probable that one or more future events will occur, triggering the requirement to make payments under the guarantee and 2) when the payment can be reasonably estimated.
Fair Value – The carrying value of cash and cash equivalents, trade receivables, taxes receivable, accounts payable, accrued liabilities, and other liabilities approximate fair value due to the immediate or short-term maturity of these financial instruments. The fair value of variable rate long term debt and notes payable reflect recent market transactions and approximate carrying value. We used other observable inputs that would qualify as Level 2 inputs to make our assessment of the approximate fair value of our cash and cash equivalents, trade receivables, taxes receivable, accounts payable, accrued liabilities, other liabilities, notes payable and variable rate long term debt. The fair value of the derivative instruments are described below.

We measure fair value by ASC Topic 820 Fair Value. ASC Topic 820 defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC Topic 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard amends numerous accounting pronouncements but does not require any new fair value measurements of reported balances. ASC Topic 820 emphasizes that fair value, among other things, is based on exit price versus entry price, should include assumptions about risk such as nonperformance risk in liability fair values, and is a market-based measurement, not an entity-specific measurement. When considering the assumptions that market participants would use in pricing the asset or liability, ASC Topic 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity's own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). The fair value hierarchy prioritizes inputs used to measure fair value into three broad levels.
In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.
Derivatives – We record derivative instruments as either an asset or liability measured at fair value. Changes in the derivative instrument's fair value are recognized currently in earnings unless specific hedge accounting criteria are met. Special accounting for qualifying hedges allows a derivative instrument's gains and losses to offset related results on the hedged item in the income statement, to the extent effective, and requires that a company must formally document, designate and assess the effectiveness of transactions that receive hedge accounting.

Income Taxes – Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company maintains a valuation

allowance for a deferred tax asset when it is deemed to be more likely than not that some or all of the deferred tax asset will not be realized.

Our estimate of the potential outcome of any uncertain tax issues is subject to management's assessment of relevant risks, facts, and circumstances existing at that time. We use a more likely than not threshold for financial statement recognition and measurement of tax position taken or expected to be taken in a tax return. To the extent that our assessment of such tax position changes, the change in estimate is recorded in the period in which the determination is made. We report tax-related interest and penalties as a component of income tax expense.

On December 22, 2017, Public Law No. 115-97 known as the Tax Cuts and Jobs Act (TCJA) was enacted. The TCJA includesincluded a number of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. federal corporate income tax rate from a maximum of 35 percent to a flat 21 percent for tax years effective January 1, 2018. The TCJA also implements a territorial tax system, provides for a one-time deemed repatriation tax on unrepatriated foreign earnings, eliminates the alternative minimum tax (AMT), makes AMT credit carryforwards refundable, and permits the acceleration of depreciation for certain assets placed into service after September 27, 2017. In addition the TJCA createscreated prospective changes beginning in 2018, including repeal of the domestic manufacturing deduction, acceleration of tax revenue recognition, capitalization of research and development expenditures, additional limitations on executive compensation and limitations on the deductibility of interest.

The Company has electedReclassifications – Certain reclassifications have been made to recognizeprior year balances to conform with the income tax effects of the TCJA in its financial statements in accordance with Staff Accounting Bulletin 118 (SAB 118), which provides guidance for the application of ASC Topic 740 Income Taxes, in the reporting period in which the TCJA was signed into law. Under SAB 118 when a Company does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the TCJA it will recognize provisional amounts if a reasonable estimate can be made. If a reasonable estimate cannot be made then no impact is recognized for the effect of the TCJA. SAB 118 permits an up to onecurrent year measurement period to finalize the measurement of the impact of the TCJA.

In May 2014 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 supersedes the revenue

recognition requirements of FASB Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition and most industry-specific guidance throughout the Accounting Standards Codification, resulting in the creation of FASB ASC Topic 606, Revenue from Contracts with Customers. ASU 2014-09 requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. This ASU provides alternative methods of retrospective adoption and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company completed its assessment of the impact of the adoption of ASU 2014-09 across all revenue streams.  This included reviewing current accounting policies and practices to identify potential differences that would result from applying the requirements under the new standard.  We completed contract reviews and validated results of applying the new revenue guidance.  We adopted ASU 2014-09 on January 1, 2018, using the modified retrospective approach which will be fully presented in our Quarterly Report on Form 10-Q for the three months ended March 31, 2018.  Based on the completed analysis, we determined that the adjustment will not have a material impact on the consolidated financial statements.

In November 2015 the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The new standard eliminates the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The amendments are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company implemented ASU 2015-17 by classifying all of it deferred tax assets (liabilities) as noncurrent on the December 31, 2017, and 2016 Balance Sheet, see Note 17.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), to increase. This update increased transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months)assets and lease liabilities on the balance sheet as a lease liability and a right-of-use asset (as defined). The ASU isdisclosing key information about leasing arrangements. This update was effective for fiscal yearsannual and interim reporting periods beginning after December 15, 2018, including interim periods within those fiscal years, with earlier applicationyears. Early adoption was permitted. Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption.  The Company has several lease agreements for which the amendments will require the Company to recognize a lease liability to make lease payments and a right-of-use asset which will represent its right to use the underlying asset for the lease term. The Company is currently reviewing the amendments to ensure it is fully compliant by the adoption date and does not expect to early adopt. As permitted by the amendments, the Company is anticipating electing an accounting policy to not recognize lease assets and lease liabilities for leases with a term of twelve months or less. The Company is currently in the process of fully evaluating the amendments and will subsequently implement new processes. In addition, the Company will change its current accounting policies to comply with the amendments with such changes as mentioned above.

In March 2016July 2018, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718):2018-11, Targeted Improvements to Employee Share-Based Payment AccountingASC 842, Leases.  ASU 2018-11 provided entities with an alternative modified transition method to elect not to recast the comparative periods presented when adopting ASC 842. The new standard provided a number of optional practical expedients in transition. The Company elected: (1) the ‘package of practical expedients’, which will reduce complexity inpermitted it not to reassess under the new standard its prior conclusions about lease identification, lease classification, and initial direct costs and (2) the use-of-hindsight. In addition, the new standard provided practical expedients for an entity’s ongoing accounting standards relatedthat the Company made, such as the (1) the election for certain classes of underlying asset to share-based payment transactions, including, among others, (1) accountingnot separate non-lease components from lease components and (2) the election for income taxes, (2) classification of excess tax benefits on the statement of cash flow, (3) forfeitures, and (4) statutory tax withholding requirements.  The ASU is effectiveshort-term lease recognition exemption for annual reporting periods beginning on or after December 15, 2016, and interim periods within those annual periods.all leases that qualify. The Company implemented the amendmentsadopted ASU 842 as of January 1, 2017.2019, using the alternative modified transition method.
In June 2018, the FASB issued ASU No. 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. ASU 2018-07 simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. The stock based compensation plan hasCompany adopted this ASU on January 1, 2019 and it did not historically generatedhave a material amounts of excess tax benefits or deficiencies and, therefore, there is no material change in the Company's financial position or results of operation, as a result of adopting this Update. For additional informationeffect on the stock-based compensation plan, see Note 16.Company’s consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350). The amendments in ASU 2017-04 simplifyamendment simplifies the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, under these amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss should not exceed the total amount of goodwill allocated to that reporting unit. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.The amendments2017. The amendment also eliminateeliminates the requirements for any reporting unit with a zero or negative carrying amount
to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The Company has goodwill from prior business combination and performs an annual impairment test or more frequently if changes or circumstances occur that would more-likely-than-not reduce the fair valueelected to early adopt this ASU on January 1, 2019. See Note 10 for a discussion of the reporting unit below its carrying value. During the year ended December 31, 2017, the Company performed its impairment assessment and determined the fair valueresults of the aggregated reporting units exceed the carrying value, such that the Company's goodwill was not considered impaired. Although the Company cannot anticipate futureour goodwill impairment assessments, based on the most recent assessment, it is unlikely that an impairment amount would need to be calculated and, therefore, the Company does not anticipate a material impact from these amendments to the Company's financial position and results of operations. The current accounting policies and processes are not anticipated to change, except for the elimination of the Step 2 analysis.testing.

NOTE 3 – ACQUISITION OF B PLANT

On May 2, 2016, we purchased the idle BASF facility adjacent to our TC facility in exchange for $2.0 million in cash, transaction costs of approximately $11,000 plus an earnout provision calculated through calendar year 2020 based upon revenue generated by the facility but limited to $1.8 million.  The cash payment was funded by working capital. The purchased facility includes production equipment similar to TC's plus equipment that broadens TC's capabilities and potential markets.  The 6.5-acre site also includes substantial storage capacity, several rail and truck loading sites and utility tie-ins to TC.  We refer to the facility as "B Plant".

We have accounted for the purchase in accordance with the acquisition method of accounting under Financial Accounting Standards Board Accounting Standards Codification Topic 805 "Business Combinations" ("ASC 805").  In accordance with ASC 805, we used our best estimates and assumptions to assign fair value to the tangible assets and liabilities acquired at the acquisition date.

The assets and liabilities acquired have been included in our consolidated balance sheets and our consolidated statements of income since the date of acquisition.

We recorded an $11.5 million bargain purchase gain on the transaction as calculated in the table below (in thousands).

Cash paid $2,011

The business acquired had been idle for the periods presented thus proforma financial presentation would be identical to our consolidated results.  We began operating the new facility in June 2016.

NOTE 43 - CONCENTRATIONS OF REVENUES AND CREDIT RISK

We sell our products and services to companies in the chemical, plastics, and petroleum industries. We perform periodic credit evaluations of our customers and generally do not require collateral from our customers. For the yearyears ended December 31, 2019, 2018, and 2017, one customer accounted for 19.6%15.0%, 13.5%, and 16.8%, respectively, of petrochemical product revenue.  For the year ended December 31, 2016, one customer accounted for 20.1% of petrochemical product revenue.  For the year ended December 31, 2015, one customer accounted for 20.1% of petrochemical productconsolidated revenue. The associated accounts receivable balances for those customersthis customer, ExxonMobil and their affiliates, were approximately $5.8$4.9 million and $11.0 million at December 31, 2017,2019 and $5.1 million at December 31, 2016.2018, respectively. The carrying amount of accounts receivable approximates fair value at December 31, 2017,2019 and 2016.

2018.
Accounts receivable serves as collateral for our amended and restated loan agreement with a domestic bank (see Note 13).

We market our products in many foreign jurisdictions. For the years ended December 31, 2017, 20162019, 2018, and 2015, petrochemical product sales2017, revenue in foreign jurisdictions accounted for approximately 20.8%21.9%, 23.5%25.5%, and 26.0%22.0% of total product salesconsolidated revenue, respectively.

SHR utilizes one major supplier for itsto purchase all our feedstock supply. The feedstock is a commodity product commonly available from other suppliers if needed. The percentage of feedstock purchased from the supplier during 2017, 2016, and 2015 was 100% 99.4% and 100%, respectively.  At December 31, 2017,2019, and 2016,2018, we owed the supplier approximately $8.5$4.5 million and $3.7$4.7 million, respectively, for feedstock purchases.

We hold our cash with various financial institutions that are insured by the Federal Deposit Insurance Corporation up to $250,000. At times during the year, cash balances may exceed this limit. We have not experienced any losses in such accounts and do not believe we are exposed to any significant risk of loss related to cash.

The carrying valueNOTE 6 - INVESTMENT IN AMAK AND DISCONTINUED OPERATIONS
At December 31, 2019 and 2018, the Company had a non-controlling equity interest of cash33.3% and cash equivalents, trade receivables, taxes receivable, accounts payable, accrued liabilities,33.4% in AMAK of approximately $32.9 million and other liabilities approximate fair value due to$38.7 million, respectively. This investment is accounted for under the immediateequity method. There are no events or short-term maturity of these financial instruments. The fair value of variable rate long term debt and notes payable reflect recent market transactions and approximate carrying value.  We used other observable inputschanges in circumstances that would qualify as Level 2 inputs to make our assessment ofmay have an adverse effect on the approximate fair value of our cashinvestment in AMAK at December 31, 2019 and cash equivalents, trade receivables,2018.
The Company committed to a plan to sell our investment in AMAK during the third quarter of 2019. Management engaged in an active program to market the investment which resulted in an agreement with certain AMAK stockholders in September 2019. Pursuant to a Share Sale and Purchase Agreement (the "Purchase Agreement") that was effective as of October 2, 2019, the Company has agreed to sell its entire 33.3% equity interest in AMAK, to AMAK and certain other existing stockholders of AMAK (collectively, the "Purchasers") for an aggregate gross purchase price (before taxes receivable, accountsand transaction expenses) of SAR 264.7 million (or approximately US$70 million), which will be payable accrued liabilities, other liabilities, notes payable and variable rate long term debt.in US Dollars. The fair valuePurchasers advanced 5% of the derivative instruments are described below.

We measure fair value by ASC Topic 820 Fair Value.  ASC Topic 820 defines fair value, establishespurchase price (or approximately $3.5 million) in the form of a framework for measuring fair value, and expands disclosures about fair value measurements.  ASC Topic 820 appliesnon-refundable deposit, which was a condition to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard amends numerous accounting pronouncements but does not require any new fair value measurements of reported balances. ASC Topic 820 emphasizes that fair value, among other things, is based on exit price versus entry price, should include assumptions about risk such as nonperformance risk in liability fair values, and is a market-based measurement, not an entity-specific measurement. When considering the assumptions that market participants would use in pricing the asset or liability, ASC Topic 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independenteffectiveness of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity's own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). The fair value hierarchy prioritizes inputs used to measure fair value into three broad levels.




Level 1 inputsLevel 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access.
Level 2 inputsLevel 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.  Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals.
Level 3 inputsLevel 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity's own assumptions, as there is little, if any, related market activity.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Commodity Financial Instruments

We periodically enter into financial instruments to hedge the cost of natural gasoline (the primary feedstock) and natural gas (used as fuel to operate the plants).  We use financial swaps on feedstock and options on natural gas to limit the effect of significant fluctuations in price on operating results.

We assess the fair value of the financial swaps on feedstock using quoted prices in active markets for identical assets or liabilities (Level 1 of fair value hierarchy).  At December 31, 2017, and 2016, we had no derivative contracts outstanding.  For additional information see Note 22.

Interest Rate Swaps

In March 2008 we entered into an interest rate swap agreement with Bank of America related to the $10.0 million term loan secured by plant, pipeline and equipment.  The interest rate swap was designed to minimize the effect of changes in the LIBOR rate.  We had designated the interest rate swapPurchase Agreement. These advances were recorded as a cash flow hedge under ASC Topic 815 (see Note 22); however, due to the new debt agreements associated with the Acquisition, we believed that the hedge was no longer entirely effective.  reduction in our investment in AMAK.
The agreement terminated in December 2017.

We assessed the fair value of the interest rate swap using a present value model that includes quoted LIBOR ratesPurchase Agreement contained various representations, warranties and the nonperformance riskindemnity obligations of the Company and Bankthe Purchasers, including the release of the Company's guarantee as described in Note 14. On January 16, 2020, the Company and the Purchasers entered into a letter agreement (the “Amendment”) providing certain amendments to the Purchase Agreement. Pursuant to the Amendment, the Long Stop Date (as defined in the Purchase Agreement) for completion of the Share Sale has been extended to March 31, 2020 to allow additional time for the parties to obtain certain required governmental approvals. Under the Purchase Agreement, the Company has certain termination rights if closing of the Share Sale does not occur on or before the Long Stop Date. The Amendment also provides that, if closing of the Share Sale does not occur on or before the extended Long Stop Date, and the Company determines in its sole discretion to further extend such date, then an amount equal to 50% of the approximately $3.5 million non-refundable deposit made by the Purchasers under the Purchase Agreement will be forfeited to the Company as liquidated damages and shall not be applied to the purchase price at closing of the Share Sale.
As all the required criteria for held-for-sale classification was met in third quarter of 2019, the investment in AMAK is classified as held-for-sale in the Consolidated Balance Sheets and reflected as discontinued operations in the Consolidated Statements of Operations for all periods presented. The assets held-for-sale are disclosed by the Company in the Corporate segment. The Company expects to have no continuing involvement with the discontinued operations after the closing date.  The gain (loss) from discontinued operations, net of tax, include our portion of the equity in earnings (losses) in AMAK as well as other administrative expenses incurred in Saudi Arabia and transaction costs.

Changes in Ownership and Other Transactions
In the first quarter of 2018, we completed an exchange of shares with certain stockholders whereby such stockholders traded 65,000 common shares of TREC in exchange for 24,489 shares of our AMAK stock. The 65,000 shares were accounted for as treasury stock. This transaction reduced our ownership percentage from 33.44% to33.41%.
In connection with the 2018 AMAK share repurchase program, we received gross proceeds of approximately $1.3 million in the first quarter of 2019. Upon completion of the share repurchase program the Company's ownership percentage in AMAK did not change from 33.44%.
In the second quarter of 2019, certain stockholders of AMAK transferred a recurring basis atportion of their shares to the CEO of AMAK as a one-time retention and performance bonus. The Company transferred 100,000 shares and the transaction reduced our ownership percentage from 33.4% to 33.3%.
At December 31, 2016:2019 and 2018, the Company had a receivable from AMAK of approximately $30,000 and $30,000, respectively, relating to unreimbursed travel and Board expenses which is included in prepaid and other assets.

The Company reviews all options to extend, terminate, or purchase its right-of-use assets at the inception of the lease and accounts for these options when they are reasonably certain of being exercised.

Prepaid expenses and other assets at December 31
Leases with an initial term of 12 months or less are summarizednot recorded on the consolidated balance sheets. Lease expense for these leases is recognized on a straight-line basis over the lease term.
The components of lease expense were as follows:

  2017  2016 
  (thousands of dollars) 
Prepaid license $1,919  $1,919 
Prepaid catalyst  779   187 
Prepaid insurance  -   797 
Spare parts  954   - 
Other prepaid expenses and assets  772   608 
   Total $4,424  $3,511 

Beginning January 1, 2017, due to the expansion of our plant assets at SHR and TC, we began inventorying spare parts for the repair and maintenance of our plant, pipeline and equipment.

NOTE 8 – INVENTORIES

Inventories include the following at December 31:

  2017  2016 
  (thousands of dollars) 
       
Raw material $3,703  $3,627 
Work in process  27   12 
Finished products  14,720   14,232 
         
Total inventory $18,450  $17,871 

Inventory serves as collateral for our amended and restated loan agreement with a domestic bank (see Note 13).

Effective January 1, 2017, we changed the inventory basis of SHR to FIFO.  We believe that the use of FIFO more accurately reflects current inventory valuation.  The drop in crude oil prices over the last several years has caused LIFO value of inventory to be above the FIFO value for each period presented.  There was no LIFO reserve in any of the periods in this filing; therefore, no change is reflected in our current statements for the retrospective application.

Prior to this change, the difference between the calculated value of inventory under the FIFO and LIFO bases generated either a recorded LIFO reserve (i.e., where FIFO value exceeds the LIFO value) or an unrecorded negative LIFO reserve (i.e., where LIFO value exceeds the FIFO value).  In the latter case, in order to ensure that inventory was reported at the lower of cost or market and in accordance with ASC 330-10, we did not increase the stated value of our inventory to the LIFO value.  At December 31, 2016, LIFO value of petrochemical inventory exceeded FIFO; therefore, in accordance with the above policy, no LIFO reserve was recorded.

NOTE 10 – GOODWILL AND INTANGIBLE ASSETS, NET

Goodwill

We performedAs discussed further in Note 2 to the Consolidated Financial Statements, during 2019 we adopted new accounting guidance and removed the second step of the goodwill impairment test. Under step two, an impairment analysis onentity was required to determine the fair value of individual assets and liabilities of a reporting unit (including unrecognized assets and liabilities) using the procedure for determining fair values in a business combination. As a result, goodwill impairment is now measured at the amount by which a reporting unit’s carrying amount exceeds its fair value, with any impairment charge limited to the carrying amount of goodwill.
Goodwill was nil and $21.8 million at December 31, 2017,2019 and 2016,December 31, 2018, respectively. Goodwill for these periods reflects accumulated impairment losses of $21.8 million and determinednil, respectively.
We evaluated our goodwill for impairment during the fourth quarter of 2019 in connection with our annual review. As part of our review, in the fourth quarter we assessed 2019 operating performance and its impact on the operating cash flows of our Specialty Wax reporting unit. We completed our annual impairment test of goodwill in accordance with ASC 350-20 Goodwill. We concluded based on this analysis that nothe estimates of fair value of our Specialty Wax reporting unit was lower than its book value, including goodwill. As a result, we recorded a non-cash impairment existed.charge of $21.8 million in the fourth quarter of 2019, representing all of the the goodwill previously allocated to this reporting unit.

NOTE 11 - INVESTMENTMINERAL PROPERTIES IN AL MASANE AL KOBRA MINING COMPANY ("AMAK")THE UNITED STATES
The principal assets of PEVM are an undivided interest in 48 patented and 5 unpatented mining claims totaling approximately 1,500 acres in southeast Nevada. The properties held by PEVM have not been commercially operated for approximately 35 years. In November 2019, PEVM entered into a sales contract which, upon completion of due diligence,

We have concluded that we have significant influence over the operating and financial policiesmay lead to liquidation of AMAK and, accordingly, should account for our investment in AMAK using the equity method.  Assubstantially all of December 31, 2017, and 2016, we had a non-controlling equity interest of approximately $45.1 million and $49.4 million, respectively.

We have received and attached to this Form 10-K the financial statements of AMAK prepared in accordance with generally accepted accounting principles in the United States of America as of December 31, 2017, and 2016, and for eachits remaining assets. Upon closing of the three years ended December 31, 2017.  These financial statements have been prepared insale, PEVM will be dissolved. Any proceeds from the functional currencysale will primarily be used to repay outstanding indebtedness of AMAK which is the Saudi Riyal (SR).  In June 1986 the SR was officially peggedPEVM owed to the U.S. Dollar (USD) at a fixed exchange rate of 1 USD to 3.75 SR.Company.

The summarized results of operation and financial position for AMAK are as follows:

The equity in the income or loss of AMAK reflected on the consolidated statements of income for the years ended December 31, 2017, 2016, and 2015, is comprised of the following:

Equity in loss of AMAK $(4,261) $(1,479) $(5,325)

In 2016 the difference between our effective share of income (loss) from our investment and our actual ownership percentage is attributable to the change in our ownership percentage during the third quarter of 2016.

A gain of approximately $16.2 million for the difference between our initial investment in AMAK and our share of AMAK's initial assets recorded at fair value was not recognized in 2008.  This basis difference is being amortized over the life of AMAK's mine which is estimated to be twelve years beginning with its commencement of production in July 2012 as an adjustment to our equity in AMAK's income or loss.

In July 2016 AMAK issued four million shares to provide additional funds for ongoing exploration work and mine start-up activities.  Arab Mining Co. ("Armico") purchased 3.75 million shares at SR 20 per share (USD$5.33 per share) and the remaining 250,000 shares are for future use as employee incentives.  We did not participate in the
offering, thereby reducing our ownership percentage in AMAK to 33.44% from 35.25%.  As a result of the equity issuance, our share of the net assets of AMAK increased approximately $3.2 million which we recognized as a gain (with a corresponding increase in our investment) in accordance with ASC 323-10-40-1.

The following table shows AMAK shareholders and percentages owned at December 31, 2017:

NamePercentage Owned
Various Saudi shareholders46.73%
Trecora Resources33.44%
Armico19.83%
Total100.00%

At December 31, 2017, we had a receivable from AMAK of approximately $121,000 relating to unreimbursed travel and Board expenses which is included in prepaid and other assets.

We assess our investment in AMAK for impairment when events are identified, or there are changes in circumstances that may have an adverse effect on the fair value or recoverability of the investment.  We consider recoverable ore reserves and the amount and timing of the cash flows to be generated by the production of those reserves, as well as, recent equity transactions within AMAK.  No impairment charges were recorded in 2017, 2016, or 2015.

NOTE 12 - MINERAL PROPERTIES IN THE UNITED STATES– ACCRUED LIABILITIES

The principal assets of PEVM are an undivided interest in 48 patented and 5 unpatented mining claims totaling approximately 1,500 acres, and a 300 ton-per-day mill located on the aforementioned properties in the PEVM Mining District in southeast Nevada.  In August 2001 seventy five unpatented claims were abandoned since they were deemed to have no future value to PEVM.  The properties held by PEVM have not been commercially operated for approximately 35 years.

(A) OnIn October 1, 2014, TOCCO, SHR, GSPL and TC (SHR, GSPL and TC collectively the "Guarantors"“Guarantors”) entered into an Amendedamended and Restated Credit Agreement ("ARC Agreement"restated credit agreement (as amended to the date hereof, the “ARC Agreement”), which originally provided (i) a revolving credit facility (the “Revolving Facility”) with revolving commitments of $40.0 million and (ii) term loan borrowings consisting of (A) a $70.0 million single advance term loan incurred to partially finance the lendersacquisition of TC (which we refer to as the “Acquisition loan”) and (B) a $25.0 multiple advance term loan facility for which from time to time are partiesborrowing availability ended on December 31, 2015 (collectively, the “Term Loan Facility” and, together with the Revolving Facility, the “Credit Facilities”).
On July 31, 2018, TOCCO and the Guarantors entered into a Fourth Amendment to the ARC Agreement (collectively,(the “Fourth Amendment”) pursuant to which the
       "Lenders") and Bank of America, N.A., a national banking association, as Administrative Agent for revolving commitments under the Lenders, and Merrill Lynch, Pierce, Fenner & Smith Incorporated as Lead Arranger.

On March 28, 2017, we entered into a Second AmendmentRevolving Facility were increased to $75.0 million. Pursuant to the Fourth Amendment, total borrowings under the Term Loan Facility were increased to $87.5 million under a single combined term loan, which comprised new term loan borrowings together with approximately $60.4 million of previously outstanding term loans under the Term Loan Facility. The $60.4 million of previously outstanding term loans included the remaining outstanding balances on the Acquisition loan and the multiple advance term loan facility described above. Proceeds of the new borrowings under the Term Loan Facility were used to repay a portion of the outstanding borrowings under the Revolving Facility and pay fees and expenses of the transaction. As of December 31, 2019, we had $3 million in borrowings outstanding under the Revolving Facility and $80.9 million in borrowings outstanding under the Term Loan Facility. In addition, we had approximately $50 million of available borrowings under our Revolving Facility at December 31, 2019. However, TOCCO’s ability to make additional borrowings under the Revolving Credit Facility at December 31, 2019 was limited by, and in the future may be limited by our obligation to maintain compliance with the covenants contained in the ARC with terms which increased the MaximumAgreement (including maintenance of a maximum Consolidated Leverage Ratio financial covenant of 3.25x to 4.00x at March 31, 2017, and 4.25x at June 30, 2017, before stepping down to 3.75x at September 30, 2017, 3.50x at December 31, 2017, and reverting to the original financial covenant of 3.25x at March 31, 2018.

NOTE 14 – ACCRUED LIABILITIES- COMMITMENTS AND CONTINGENCIES

Guarantees
Accrued liabilitiesOn October 24, 2010, we executed a limited guarantee in favor of the Saudi Industrial Development Fund ("SIDF") whereby we agreed to guaranty up to 41% of the SIDF loan to AMAK in the principal amount of 330.0 million Saudi Riyals (US$88.0 million) (the "Loan"). The term of the loan was originally through June 2019. As a condition of the Loan, SIDF required all stockholders of AMAK to execute personal or corporate guarantees; as a result, the Company's guarantee is for approximately 135.3 million Saudi Riyals (US$36.1 million). The loan was necessary to continue construction of the AMAK facilities and provide working capital needs. We received no consideration in connection with extending the guarantee and did so to maintain and enhance the value of our investment. On July 8, 2018, the Loan was amended to adjust the repayment schedule and extend the repayment terms through April 2024. The total amount outstanding on the Loan at December 31, are summarized as follows:2019 was 275.0 million Saudi Riyals (US$73.3 million). See additional discussion including the release of the guarantee in connection with the AMAK sale in Note 6.

Litigation
The Company is periodically named in legal actions arising from normal business activities. We evaluate the merits of these actions and, if we determine that an unfavorable outcome is probable and can be reasonably estimated, we will establish the necessary reserves. We are not currently involved in legal proceedings that could reasonably be expected to have a material adverse effect on our business, prospects, financial condition or results of operations. We may become involved in material legal proceedings in the future.
Supplier Agreements
In accordance with our supplier agreements, on a recurring monthly basis, the Company commits to purchasing a determined volume of feedstock in anticipation of upcoming requirements. Feedstock purchases are invoiced and recorded when they are delivered. As of December 31, 2019 and 2018, the value of the remaining undelivered feedstock approximated $3.5 million and $3.9 million, respectively.
From time to time, we may incur shortfall fees due to feedstock purchases being below the minimum amounts as prescribed by our agreements with our suppliers. The shortfall fee expenses were not significant for the years ended December 31, 2019, 2018, and 2017.
Environmental Remediation
Amounts charged to expense for various activities related to environmental monitoring, compliance, and improvements were approximately $868,000 in 2019, $745,000 in 2018 and $593,000 in 2017.
NOTE 15 - COMMITMENTS AND CONTINGENCIES

Guarantees

On October 24, 2010, we executed a limited guarantee in favor of the Saudi Industrial Development Fund ("SIDF") whereby we agreed to guaranty up to 41% of the SIDF loan to AMAK in the principal amount of 330.0 million Saudi Riyals (US$88.0 million) (the "Loan"). The term of the loan is currently through June 2022.  As a condition of the Loan, SIDF required all shareholders of AMAK to execute personal or corporate guarantees; as a result, the Company's guarantee is for approximately 135.3 million Saudi Riyals (US$36.1 million). The loan was necessary to continue construction of the AMAK facilities and provide working capital needs.  Our current assessment is that the probability of contingent performance is remote based on our analysis of the contingent portion of the guarantee which included but was not limited to the following:  (1) the SIDF has historically not called guarantees, (2) the value of the assets exceeds the amount of the loan (3) the other shareholders have indicated that they would prioritize their personal guarantees ahead of the corporate guarantee, and (4) according to Saudi Arabian legal counsel, assets outside of Saudi Arabia are protected from the Saudi Court System.  We received no consideration in connection with extending the guarantee and did so to maintain and enhance the value of our investment.  Our non-contingent and immediate obligation to stand ready to make payments if the events of default under the guarantee occur was not material to the financial statements.  The total amount outstanding to the SIDF at December 31, 2017, and 2016 was 305.0 million and 310.0 million Saudi Riyals (US$81.3 million and $82.7 million), respectively.

During 2017, AMAK did not make certain scheduled payments on their loan. AMAK obtained a waiver from SIDF regarding the missed payments and is currently working with SIDF to renegotiate the terms and repayment schedule of the loan agreement.  We do not believe that these events will result in any performance under our guarantee.

Operating Lease Commitments

We have operating leases for the rental of approximately 335 railcars for shipping purposes with expiration dates through 2026.  Invoices are received and paid on a monthly basis.  The total amount of the commitment is approximately $17.8 million over the next 9 years.

We also have an operating lease for our office space in Sugar Land, TX.  The expiration date for this lease is January 2018.  The total amount of the commitment is less than $10,000.  We are in the process of negotiating a new lease for the same space.  In addition, we are required to make periodic payments for property taxes, utilities and common area operating expenses.

In addition, we have operating leases for other equipment such as forklifts and copiers with varying expiration dates through 2020.  The total amount of the commitment is less than $50,000.

Future minimum property and equipment lease payments under the non-cancelable operating leases at December 31, 2017, are as follows:

Year Ending December 31,
   
  (thousands of dollars) 
2018 $3,393 
2019  3,341 
2020  3,250 
2021  3,120 
2022  1,498 
Thereafter  3,177 
Total $17,779 

Rental expense for these operating leases for the years ended December 31, 2017, 2016, and 2015 was $4.4 million, $4.2 million and $4.2 million, respectively.

We may become involved in material legal proceedings in the future.

On September 25, 2011, we awarded 10 year options to Director Joseph Palm for 80,000 shares with an exercise price equal to the closing price of the stock on September 23, 2011, (the latest closing date available) which was $3.52.  These options vest over 4.67 years with the first 20,000 vesting on May 19, 2013, and subsequent 20,000 share lots vesting each anniversary of that date subsequent until entirely vested.  Compensation expense recognized for 2017, 2016 and 2015 was approximately $0, $27,000, and $65,000, respectively.

On May 2, 2011, we awarded 10 year options to Director John Townsend for 100,000 shares.  These options have an exercise price equal to the closing price of the stock on May 2, 2011, which was $4.09 and vest in 20% increments over a 5 year period.  Compensation expense recognized during 2017, 2016, and 2015 in connection with this award was approximately $0, $27,000 and $80,000, respectively.

On January 12, 2011, we awarded 10 year options to key employees for 391,000 shares.  These options have an exercise price equal to the closing price of the stock on January 12, 2011, which was $4.86 and vest in 25% increments over a 4 year period.  Compensation expense recognized during 2017, 2016, and 2015 in connection with this award was approximately $0, $0 and $40,000, respectively.

The fair value of the 2011 options granted was calculated using the Black-Scholes option valuation model with the following range of assumptions:

Expected volatility96% to 413%
Expected dividendsNone
Expected term (in years)5-10
Risk free interest rate1.26% to 3.34%

A summary of all 2010 issuances is as follows:

In February 2010 we awarded 500,000 options to non-employee directors for their service during 2010 subject to attendance and service requirements.  These options vest over a 5 year period.  The exercise price of these options is $2.82 based upon the closing price on February 23, 2010.  Directors' fee expense recognized during 2017, 2016 and 2015 in connection with this award was approximately $0, $0 and $9,000, respectively.

The fair value of the 2010 options granted was calculated using the Black-Scholes option valuation model with the following range of assumptions:

A summary of unvested 2009 issuances is as follows:

On July 2009 we awarded two stock options to Mr. Hatem El Khalidi and his wife, Ingrid El Khalidi, tied to the performance of AMAK as follows: (1) an option to purchase 200,000 shares of the Company's common stock with an exercise price of $3.40 per share, equal to the closing sale price of such a share as reported on the public market on July 2, 2009, provided that said option may not be exercised until such time as the first shipment of ore from the Al Masane mining project is transported for commercial sale by AMAK, and further that said option shall terminate and be immediately forfeited if not exercised on or before June 30, 2012; and (2) an option to purchase 200,000 shares of the Company's common stock with an exercise price equal to the closing sale price of such a share as reported on the Nasdaq Stock Market on July 2, 2009, provided that said option may not be exercised until such time as the Company receives its first cash dividend distribution from AMAK, and further that said option shall terminate and be immediately forfeited if not exercised on or before June 30, 2019.  Compensation expense of approximately $0, $49,000 and $97,000 was recognized during the years ended December 31, 2017, 2016, and 2015, respectively,
related to the options awarded to Mr. El Khalidi. Approximately $413,000 was reversed during 2012 due to the performance condition associated with 200,000 shares in options not being met as required by the terms of the award by June 30, 2012.  Previously, on May 9, 2010, the Board of Directors determined that Mr. El Khalidi forfeited all options and other retirement benefits when he made various demands against the Company and other AMAK Saudi shareholders which would benefit him personally and were not in the best interests of the Company and its shareholders.  As discussed in Note 15 we are currently in litigation with Mr. El Khalidi and in connection therewith, we are currently reviewing our legal right to withdraw the options and benefits.  However, as of December 31, 2017, the options vesting upon a cash dividend distribution from AMAK continue to be shown as outstanding.

The aggregate intrinsic value of options was calculated as the difference between the exercise price of the underlying awards and the quoted price of our common stock. At December 31, 2017,2019, options and warrants to purchase approximately 1.30.1 million shares of common stock were in-the-money.

Since no options were granted, the weighted average grant-date fair value per share of options granted during the years 2019, 2018, and 2017 2016,was nil. During 2019, 2018, and 2015 was $0.  During 2017 2016, and 2015 the aggregate intrinsic value of options and warrants exercised was approximately $164,000, $237,000$141,000, $2,630,000 and $2,300,000$164,000 respectively, determined as of the date of option exercise.

The Company received approximately $25,000, $11,000nil, $912,000 and $123,000$25,000 in cash from the exercise of options during 2019, 2018 and 2017, 2016respectively. Of the 85,000 stock options and 2015, respectively.  Some ofwarrants exercised, the options were exercised via a net transaction.Company only issued approximately 11,000 shares due to cashless transactions. The tax benefit realized from the exercise was insignificant.

As of December 31, 2017,2019, there was no unrecognized compensation costs related to non-vested share-based compensation.
Post-retirement compensation of approximately $680,000 during the year ended December 31, 2018 was reversed related to options awarded to a former CEO and board member in July 2009. On May 9, 2010, the Board of Directors determined that he had forfeited these options and other retirement benefits when he made various demands against the Company and other AMAK shareholders which would benefit him personally and were not in the best interests of the Company and its shareholders. The Company was successful in litigating its right to withdraw the options and benefits and as such, these options and benefits were reversed during the second quarter of 2018. 
Restricted Stock and Restricted Stock Unit Awards
Generally, restricted stock and restricted stock unit awards are granted annually to officers and directors of the Company under the provisions of the Plan. Restricted stock units are also granted ad hoc to attract or retain key personnel, and the terms and conditions under which these restricted stock units vest vary by award. The fair market value of restricted stock units granted is equal to the Company’s closing stock price on the date of grant. Restricted stock units granted generally vest ratably over periods ranging from 2.5 to 5 years. Certain awards also include vesting provisions based on performance metrics. Upon vesting, the restricted stock units are settled by issuing one share of Company common stock per unit.
A summary of the status of the Company's restricted stock units activity is as follows:

The Company has recognizedOn December 22, 2017, the provisional tax impacts relatedTax Cuts and Jobs Act of 2017 ("TCJA") was signed into law making significant changes to the acceleration of depreciation and included these amounts in its consolidated financial statements for the year ended December 31, 2017.Internal Revenue Code. The ultimate impact may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued, and actions the Company may take as a result of the TCJA. The Company did not identify items for which the income tax effects of the TCJA have not been completed and a reasonable estimate could not be determined as of December 31, 2017.

The changes to existing U.S. tax laws as a result of the TCJA, which will havehad the most significant impact on the Company's federal income taxes are as follows:

Reduction of the U.S. Corporate Income Tax Rate - The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured
using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the TCJA, the Company revalued its ending net deferred tax liabilities at December 31, 2017.

Acceleration of Depreciation - The Company recognized a provisional reduction to net deferred tax assets attributable to the accelerated depreciation for certain assets placed into service after September 27, 2017. ThisThe provisional adjustment resulted in an increase inestimate was finalized including consideration of TCJA on long term construction projects.
The Company elected to recognize the income tax receivableeffects of approximately $961,000.the TCJA in its financial statements in accordance with Staff Accounting Bulletin 118 (SAB 118), which provides guidance for the application of ASC Topic 740 Income Taxes, in the reporting period in which the TCJA was signed into law. During the fourth quarter of 2018, we completed our accounting for the Tax Act based on the current regulatory guidance available at the end of the SAB 118 measurement period and recorded no material net adjustments to our provisional estimate.

Tax effects of temporary differences that give rise to significant portions of federal and state deferred tax assets and deferred tax liabilities were as follows:

In connection with the proceeds received from AMAK in connection with its share repurchase program (See Note 6), the Company accrued a deferred tax asset (foreign tax credit) and the corresponding liability for the Saudi Arabian tax which was settled during 2019.
We provided a valuation allowance in 20172019 and 20162018 against certain deferred tax assets because of uncertainties regarding their realization. As of December 31, 2019 and 2018, we have federal income tax net operating losses ("NOLs") carryforwards of $56.6 million and $43.2 million, respectively. The changeNOLs were created after the enactment of TCJA and therefore do not expire but may offset only 80% of taxable income in valuation allowance for 2017 of $150 was due to the re-measuring of the valuation allowance due to the TCJA.  There was no change in the valuation allowance for 2016.

In 2018, we completed an exchange of shares with certain shareholders whereby such shareholders traded 65,000 common shares of TREC in exchange for 24,489 shares of our AMAK stock.  The 65,000 shares were accounted for as treasury stock.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors rescinded its original commodity trading resolution from 1992and
Shareholders of Al Masane Al Kobra Mining Company
Najran, Kingdom of Saudi Arabia

Opinion on the Financial Statements
We have audited the accompanying balance sheets of Al Masane Al Kobra Mining Company (the Company) as of December 31, 2019 and replaced it with a new resolution.  The 2009 resolution allows2018, and the related statements of operations, changes in shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2019, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion
These financial statements are the responsibility of the Company���s management. Our responsibility is to establishexpress an opinion on the Company’s financial statements based on our audits. We are a commodity futures accountpublic 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 PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of maximizing our resources and reducing risk as pertaining to our purchases of natural gas and feedstock for operational purposes by employing a four step process. This process, in summary, includes, (1) education of employees who are responsible for carrying outexpressing an opinion on the policy, (2) adoption of a derivatives policy by the Board explaining the objectives for use of derivatives including accepted risk limits, (3) implementation of a comprehensive derivative strategy designed to clarify the specific circumstances under which we will use derivatives, and (4) establishment and maintenance of a set of internal controls to ensure that alleffectiveness of the derivatives transactions taking place are authorizedCompany’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the 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 regarding the amounts and disclosures in accord with the policiesfinancial statements. Our audits also included evaluating the accounting principles used and strategies that have been enacted.  On August 31, 2009, the Company adopted a formal risksignificant estimates made by management, policy which incorporates the above process, as well as established a "hedge committee" for derivative oversight.

We endeavor to acquire feedstock and natural gas atevaluating the lowest possible cost.  The primary feedstock (natural gasoline) is traded over the counter and not on organized futures exchanges.  Financially settled instruments (fixed price swaps) are the principal vehicle used to give some predictability to feed prices. We do not purchase or hold any derivative financial instruments for trading purposes.

Interest Rate SwapsWe have served as the Company’s auditor since 2013.

On Riyadh, Kingdom of Saudi Arabia
March 21, 2008, SHR entered into a pay-fixed, receive-variable interest rate swap agreement with Bank of America related to the $10.0 million (later increased to $14 million) term loan secured by plant, pipeline and equipment. The effective date of the interest rate swap agreement was August 15, 2008, and terminated on December 15, 2017.  We received credit for payments of variable rate interest made on the term loan at the loan's variable rates, which are based upon the London InterBank Offered Rate (LIBOR), and paid Bank of America an interest rate of 5.83% less the credit on the interest rate swap.  We originally designated the transaction as a cash flow hedge according to ASC Topic 815, Derivatives and Hedging.  Beginning on August 15, 2008, the derivative instrument was reported at fair value with any changes in fair value reported within other comprehensive income (loss) in the Company's Statement of Stockholders' Equity.  We entered into the interest rate swap to minimize the effect of changes in the LIBOR rate.11, 2019

The following tables detail (in thousands) the impact the agreement had on the financial statements:

Due to the new debt agreements associated with the Acquisition, we believed that the hedge was no longer entirely effective.  Due to the time required to make the determination and the immateriality of the hedge, we began treating the interest rate swap as ineffective as of October 1, 2014.

NOTE 23- POST-RETIREMENT OBLIGATIONSNote 1 – Organization and Business

Organization
In January 2008 an amended retirement agreement, replacing the February 2007 agreement, was entered into with Hatem El Khalidi. The amended agreement provided $6,000 per month in benefits to Mr. El Khalidi upon his retirement for the remainder of his life. Additionally, upon his death $4,000 per month would be paid to his surviving spouse for the remainder of her life. A health insurance benefit was also to be provided.  An additional $382,000 was accrued in January 2008 for the increase in benefits. A liability of approximately $922,000 and $918,000 based upon an annuity single premium value contract was outstanding at December 31, 2017, and 2016, respectively, and was included in post-retirement benefits.  Mr. El Khalidi retired effective June 30, 2009.  As of December 31, 2017, no payments have been made pursuant to this agreement.

In June 2009 the Company's Board of Directors awarded Mr. El Khalidi a retirement bonus in the amount of $31,500 for 42 years of service.  While there is no written policy regarding retirement bonus compensation, the Company has historically awarded all employees (regardless of job position) a retirement bonus equal to $750 for each year of service.  Since Mr. El Khalidi was employed by the Company for 42 years, the Board of Directors voted to award him a $31,500 retirement bonus, consistent with that provided to all other retired employees. This amount was outstanding at December 31, 2017, and 2016, and was included in post-retirement benefits.

On May 9, 2010, the Board of Directors terminated the retirement agreement, options, retirement bonus, and any outstanding directors' fees due to Mr. El Khalidi; however, due to the litigation discussed in Note 15, all amounts remain outstanding until a resolution is achieved.

In July 2015 we entered into a retirement agreement with former CEO, Nicholas Carter which provides continued welfare benefits for Mr. Carter and his wife for life at the same cost sharing basis as regular employees.  Approximately $249,000 and $265,000 was outstanding at December 31, 2017, and 2016, respectively, and included in post-retirement benefits.  For the period ended December 31, 2017, and 2016, approximately $16,000 and $12,000, respectively had been paid.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Opinion on the Financial Statements
We have audited the accompanying balance sheets of Al Masane Al Kobra Mining Company (the Company) asis a Saudi Arabian closed joint stock company approved by the Minister of December 31, 2017Commerce and 2016,Industry Decree Number 247/Q dated 9/10/1428 (October 21, 2007) and registered in Jeddah under Commercial Registration No. 4030175345 on 7/1/1429 (January 16, 2008). During 2015, the head office was moved from Jeddah to Najran. Accordingly, Najran Commercial Registration No. 5950017523 dated 03/11/1431H (October 11, 2010) was modified to be the main Commercial Registration. Unless the context requires otherwise, references to “we”, “us”, “our”, “AMAK”, and the related statements“Company” are intended to mean Al Masane Al Kobra Mining Company. All amounts are expressed in Saudi Riyals (SR) unless otherwise noted.
During 2009, the authorized capital of operations, comprehensive income, changes in shareholders' equity, and cash flows forthe Company was 450,000,000 consisting of 45 million shares of 10 each of which 50% were issued for cash. The remaining 50% were issued for the yearscontribution of mining rights and assets from Trecora Resources (Trecora) subject to Trecora’s liability for a loan in the three-yearamount of 41,250,000 due to the Ministry of Finance and National Economy. The mining rights in Al Masane mine were originally granted by Royal Decree Number M/17 effective 1/12/1413 (May 22, 1993) for a period of thirty years, with a right of renewal for a further period of twenty years to Trecora. The mining rights granted Trecora the right of exploitation in Al Masane mine located in Najran, Saudi Arabia, with an area of 44 square kilometers for a surface rental of 10,000 per square kilometer per year, i.e. 440,000 per year. As per the Ministry of Petroleum and Mineral Resources resolution dated 13/9/1429 (13/9/2008) and the ministry subsequent letter dated 2/1/1430 (30/12/2008), the aforementioned rights were transferred to us.
During 2011, the Company increased its authorized share capital by SR50,000,000 to SR500,000,000 and issued 5,000,000 shares of 10 each at a price of SR28 each resulting in a share premium of SR90,000,000. The entire 5,000,000 shares were issued for cash to Arab Mining Company (ARMICO) headquartered in Amman, Jordan.

During 2018 the Company increased its authorized share capital by SR40,000,000 to SR820,000,000 and issued 4,000,000 shares of 10 each by transferring from share premium accounts.
During the Company’s Extraordinary General Assembly Meeting in October of 2018, the shareholders approved to repurchase up to 2,500,000 shares from the shareholders at a price of SR30 each and to register these shares as treasury shares. In December 2018, the Board unanimously approved this proposal and authorized the CEO to proceed with the repurchase. The Company advanced certain shareholders their portion of these proceeds in 2018. During the first quarter of 2019, the Company finalized the transaction and repurchased 2,490,445 shares for approximately SR74,713,000.
On October 2, 2019, the Company and certain shareholders of the Company (collectively, the “Purchasers”) entered into a Share Sale and Purchase Agreement (“Purchase Agreement”) with Trecora to purchase their entire equity interest in the Company for an aggregate gross purchase price of approximately SR264,700,000. The Purchase Agreement contains various representations, warranties and indemnity obligations of the Purchasers and Trecora. Initially, the Purchase Agreement required the transaction to close by November 25, 2019. On January 16, 2020, the Purchasers and Trecora entered into an amendment to extend the close date to March 31, 2020 to allow additional time for the parties to obtain certain required governmental approvals. As required by the Purchase Agreement, the Purchasers advanced 5% of the purchase price to Trecora. The Company’s share of the advance was approximately, SR2,855,000 and is included in advances to shareholders in the accompanying balance sheet for the year ended December 31, 2017, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our 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 PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the 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 regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.2019.

During 2015, the head office was moved from Jeddah to Najran. Accordingly, Najran Commercial Registration No. 5950017523 dated 03/11/1431H (October 11, 2010) was modified to be the main Commercial Registration. Unless the context requires otherwise, references to "we", "us", "our", "AMAK", and the "Company" are intended to mean Al Masane Al Kobra Mining Company. All amounts are expressed in Saudi Riyals (SR) unless otherwise noted.

During 2009 the authorized capital of the Company was 450,000,000 consisting of 45 million shares of 10 each of which 50% were issued for cash. The remaining 50% were issued for the contribution of mining rights and assets from Trecora Resources (Trecora) subject to Trecora's liability for a loan in the amount of 41,250,000 due to the Ministry of Finance and National Economy. The mining rights in Al Masane mine were originally granted by Royal Decree Number M/17 effective 1/12/1413 (May 22, 1993) for a period of thirty years, with a right of renewal for a further period of twenty years to Trecora. The mining rights granted Trecora the right of exploitation in Al Masane mine located in Najran, Saudi Arabia, with an area of 44 square kilometers for a surface rental of 10,000 per square kilometer per year, i.e. 440,000 per year.  As  per  the  Ministry  of  Petroleum  and  Mineral  Resources  resolution  dated 13/9/1429   (13/9/2008)   and   the   ministry   subsequent   letter   dated   2/1/1430   (30/12/2008),   the aforementioned rights were transferred to us.

During 2011 the Company increased its authorized share capital by SR50,000,000 to SR500,000,000 and issued 5,000,000 shares of 10 each at a price of SR28 each resulting in a share premium of SR90,000,000. The entire 5,000,000 shares were issued for cash to Arab Mining Company (ARMICO) headquartered in Amman, Jordan.

During 2013 the Company increased its authorized share capital by SR50,000,000 to SR550,000,000 and issued 5,000,000 shares of 10 each at a price of SR30 each resulting in a share premium of SR100,000,000. The shares were issued for cash to existing shareholders.

During 2015 the Company increased its authorized share capital by SR190,000,000 to SR 740,000,000 and issued 19,000,000 shares of 10 each by transferring from share premium accounts.

During 2016 the Company increased its authorized share capital by SR40,000,000 to SR 780,000,000 and issued 4,000,000 shares of 10 each at a price of SR20 each resulting in a share premium of SR35,092,840.

During 2017 the Company increased share premium by SR2,453,580 for share that were previously issued.

Except for Trecora and ARMICO, all other shareholders are Saudi nationals or companies wholly owned by Saudi nationals. Our share capital is owned by the shareholders as follows:

Business and operations
Our principal activity is to produce zinc and copper concentrates and silver and gold doré as per the license Number 993/2 dated 16/7/1428 (July 31, 2007) issued by Saudi Arabian General Investment Authority (SAGIA). We commenced our commercial production on July 1, 2012. During 2015, we received a new mining lease for an area near our current mining area for the Guyan ancient mine.

On 16/11/1428 (November 26, 2007), while the Company was in the registration process, the Company signed a contract with China National Geological and Mining Corporation (CGM) for underground mine rehabilitation, pre-production activity, and on-going mine development/production and with Nesma & Partners Contracting Company Limited (Nesma) for engineering, procurement, construction, commissioning and hand over of the concentrator surface works and the related infrastructure facilities. The handover of these facilities was finalized on November 28, 2011. In late 2014, we renegotiated a more favorable plant operations and maintenance contract with CGM. CGM ran our mining operations until November 2015, at which time the Board of Directors cancelled the CGM and Nesma contract and temporarily suspended operations of the Company.  See Note 8.

Note 1 – Organization and Business – (Continued)

Business and operations - continued
This planned, temporary shutdown of the facility was due to the continued depressed commodity price environment as well as needs for renovation and maintenance. In February 2016, we entered into a new operating and rehabilitation contract with a different vendor under more favorable terms.  We resumed operations in the first quarter of 2017 and generated enough ore for two shipments in 2017 and have four scheduled shipments in 2018.

Our focus during the renovation focused on improving recoveries overall and upgrading the precious metals circuit through the installation of SART (sulfidization, acidification, recycling, and thickening) modifications which are expected to lower chemical use, thereby reducing operating costs. In addition, processing of certain gold-bearing waste dumps from historical mining at the newly acquired Guyan mining license area has begun and fold extraction is in process.  An extensive exploration program for the rest of Guyan mining lease has been completed.


Note 2 - Summary of Significant Accounting Policies

The accompanying financial statements have been prepared using U.S. generally accepted accounting principles. The following is a summary of our significant accounting policies:

Cash and cash equivalents
We consider all highly-liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Accounts receivable
We evaluate the collectability of our accounts receivable and the adequacy of the allowance for doubtful accounts based upon historical experience and any specific customer financial difficulties of which the Company becomes aware. During the years ended December 31, 2017, 2016,2019, 2018, and 2015,2017, we sold our concentrates and doré pursuant to a sales contractcontracts with primarily one customer. No amounts have been written off for the years ended December 31, 2017, 2016,2019, 2018, and 2015.2017. In addition, we determined that an allowance for doubtful accounts was not necessary at December 31, 20172019 and 2016.  Due to the shutdown of operations, we had no outstanding accounts receivable at December 31, 2016.

2018.
Inventories
The components of inventories include mill stockpiles, precious metal doré, chemicals, and mining supplies. Inventories are stated at the lower of weighted-average cost or market. Costs of mill stockpiles inventory include labor and benefits, supplies, energy, depreciation, depletion, amortization, and other necessary costs incurred with the extraction and processing of ore. Corporate general and administrative costs are not included in inventory costs.

Because it is generally impracticable to determine the minerals contained in mill stockpiles by physical count, reasonable estimation methods are employed. The quantity of material delivered to the mill stockpiles is based on surveyed volumes of mined material and daily production records. Expected mineral recovery rates from the mill stockpiles are determined by various metallurgical testing methods.

Property and equipment
Property and equipment is carried at cost less accumulated depreciation. Expenditures for replacements and improvements are capitalized. Costs related to periodic maintenance are expensed as incurred. Depletion of the mining assets is determined using the unit-of-production method based on total estimated proven and probable reserves. Depletion and amortization using the unit-of-production method is recorded upon extraction of the ore, at which time it is allocated to inventory cost and then included as a component of cost of goods sold. Other assets are depreciated on a straight-line basis over their estimated useful lives ranging from 3 to 20 years.

Borrowing costs that are directly attributable to the acquisition, construction or production of assets are capitalized as part of the cost of those assets. Assets under construction are capitalized in the construction in progress account. Upon completion, the cost of the related asset is transferred to the appropriate category of property and equipment.











Note 2 - Summary of Significant Accounting Policies - (Continued)

Development costs
Mineral exploration costs, as well as drilling and other costs incurred for the purpose of converting mineral resources to proven and probable reserves or identifying new mineral resources are charged to expense as incurred. Development costs are capitalized beginning after proven and probable reserves have been established. Development costs include costs incurred in mine pre-production activities undertaken to gain access to proven and probable reserves, including shafts, drifts, ramps, permanent excavations, infrastructure and removal of overburden. These costs are deferred net of the proceeds from the sale of any production during the development period and then amortized using an estimated unit-of-production method. If a mine is no longer considered economical, the accumulated costs are charged to the statement of operations in the year in which the determination is made.

Asset impairment
We review and evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the carrying amounts may not be recoverable. Long-lived assets are evaluated for impairment under the two-step model. When events or circumstance suggest impairment of long-lived assets, estimated undiscounted future net cash flows are calculated using future estimated commodity prices, proven and probable reserves, and estimated net proceeds from the disposition of assets on retirement, less operating, sustaining capital, and reclamation costs. If it is determined that an impairment exists, an impairment loss is measured as the amount by which the asset carrying value exceeds its fair value. Fair value is generally determined using valuation techniques such as estimated future cash flows. Because the cash flows used to assess recoverability of our long-lived assets and measure fair value of our mining operations require us to make several estimates and assumptions that are subject to risk and uncertainty, changes in these estimates and assumptions could result in the impairment of our long-lived asset values.

Based on our evaluation, we recorded no impairment losses during the years ended December 31, 2017, 20162019, 2018 and 2015.

2017.
End-of-service indemnities
Employee end-of-service benefits are accrued for the benefit of employees under the terms and conditions of Saudi Labor Law and Regulations and their employment contracts. End-of-service indemnities are provided for and accrued in the financial statements based on the respective employees' salaries and length of service.


Note 2 - Summary of Significant Accounting Policies - (Continued)

Pre-export Advances
At times we receive advances on a pre-export basis against a portion of our inventory on hand prior to shipment. These advances bear interest at 2.5% and are repaid from the proceeds from final concentrate sales. We did not have an outstanding advance liability at December 31, 2017 and 2016.

Foreign currency
Our functional currency is the Saudi Riyal (SR). In June 1986, the Saudi Riyal was officially pegged to the U.S. Dollar at a fixed exchange rate of 1 U.S. Dollar to 3.75 riyals. Foreign currency transactions are translated into Saudi Riyals at the rates of exchange prevailing at the time of the transactions. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are translated at the exchange rates prevailing at that date. Any gains and losses from settlement and translation of foreign currency transactions are included in the statement of operations. There were no material foreign-currency exchange gains or losses or translation adjustments during the years ended December 31, 2017, 2016,2019, 2018 and 2015.

2017.
Leasing arrangements
We periodically lease operating equipment, facilities, and office buildings. Rentals payable under operating leases are charged to the statements of operations on a straight-line basis over the term of the relevant lease. For any capital leases, the present value of future minimum lease payments at the inception of the lease is reflected as an asset and a liability in the balance sheet. Amounts due within one year are classified as short-term liabilities and the remaining balance as long-term liabilities. Finance charges are charged to the statement of operations. At December 31, 2017, we had no outstanding capital lease obligations.

Operating lease expense amounted to approximately SR1,454,000, SR442,000SR4,015,000, SR1,619,000 and SR696,000SR1,454,000 for the years ended December 31, 2019, 2018 and 2017, 2016 and 2015, respectively.

Environmental costs
Environmental costs are expensed or capitalized, depending upon their future economic benefits. Accruals for such expenditures are recorded when it is probable that obligations have been incurred and the costs can reasonably be estimated. Ongoing compliance costs are expensed as incurred.




Note 2 - Summary of Significant Accounting Policies - (Continued)

Asset retirement obligations and costs
We record the fair value of our estimated asset retirement obligations (AROs) associated with tangible long-lived assets in the period in which the obligation is incurred. AROs associated with long-lived assets are those for which there is a legal obligation to settle under various laws, statues, or regulations. These obligations, which are initially estimated based on discounted cash flow estimates, are accreted to full value over time through charges to cost of revenues. In addition, asset retirement costs (ARCs) are capitalized as part of the related asset'sasset’s carrying value and are depreciated (primarily on a unit-of-production basis) over the asset'sasset’s respective useful life.

Asset retirement obligations and costs - continued
Our AROs consist primarily of costs associated with mine reclamation and closure activities and are included in deferred mine closure costs on the accompanying balance sheets. At least annually, we review our ARO estimates for changes in the projected timing and changes in cost estimates and additional AROs incurred during the period.

Zakat and income tax
We are subject to the Regulations of the General Authority of Zakat and Tax (GAZT) in the Kingdom of Saudi Arabia. Under these regulations, Zakat is payable at 2.5% on the basis of the portion of our Zakat base attributable to our Saudi stockholders, and income tax is payable at 20% on the portion of our taxable income attributable to our non-Saudi stockholders. Zakat and income tax are provided on an accrual basis. Any difference in the estimate is recorded when the final assessment is approved, at which time the provision is cleared.

We account for deferred income taxes on non-Saudi owners utilizing an asset and liability method, whereby deferred tax assets and liabilities are recognized based on the tax effects of temporary differences between the financial statements and the income tax basis of assets and liabilities, as measured by the effective tax rate. When appropriate, we evaluate the need for a valuation allowance based on a more likely than not threshold to reduce deferred tax assets to estimated recoverable amounts.

We account for uncertain income tax positions using a threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. We report tax-related interest and penalties as a component of Zakat and income tax expense. We recognized no material adjustment for unrecognized income tax liabilities. Zakat
Revenue recognition
The Company adopted ASC 606, Revenues from Contracts with Customers, effective January 1, 2019, on a modified retrospective basis, applying the standards to all contracts that are not completed as such date. The Company’s revenues primary consists of sales of copper and income tax returns forzinc. Other than increased disclosures, the years from 2010 to 2016 are currently under review with GAZT.



Note 2 - Summary of Significant Accounting Policies - (Continued)

Reclassifications
Certain reclassifications have been made to the prior periods to conform with current year presentation.  In addition, certain reclassifications have been made to the Balance Sheets for the year ended December 31, 2016, related to our adoption of FASB ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes as noted below in Notes 2 and 9.

Revenue recognitionthe new guidance did not have an impact on the Company’s revenue recognition.
We sell our products pursuant to individual sales contracts entered into with a customer who acts as an intermediary and resells our products to end users. The Company considers each sales contract to be a single performance obligation, represented by the delivery of a series of distinct goods that are substantially the same, with the same pattern of transfer to the Company's customer. The Company concluded this as, based on the nature of its contracts, the customer receives the benefit of mineral sold as it is shipped per the terms of the commercial invoice at each delivery date. In addition, the Company considers that it has a right to consideration from its customers in an amount that corresponds directly to the value transferred to those customers that being the quantity of mineral delivered at the price per unit delivered. Accordingly, the Company recognizes revenue at the amount to which it has the right to invoice (the invoice practical expedient), as it believes that this method is a faithful depiction of the transfer of goods to its customers.
Revenue is recognized when or as the performance obligations are satisfied, when the Company transfers control of the goods and title and risk of loss passpasses to the customer. Control is transferred generally upon the completion of loading the material as the point of origin. This is the point which the customer and when collectability is reasonably assured. The passing ofobtains legal title and risk of loss to the customer is based on termsproduct as well as the ability to direct the use of and obtain substantially all the remaining benefits of ownership of the sales contract, generally upon shipment or delivery of product.

assets.
Sales are recorded based on a provisional sales price or a final sales price calculated in accordance with the terms specified in the relevant sales contract. Under the long-established structure of sales agreements prevalent in the industry, the copper and zinc contained in concentrate is generally "provisionally"“provisionally” priced at the time of shipment. The provisional price received at the time of shipment is later adjusted to a "final"“final” price based on quoted monthly average spot prices on the London Metal Exchange (LME) for a specified future month. We record revenues at the time of shipment (when title and risk of loss pass) based on then-current LME prices, and we account for any changes between the sales price recorded at the time of shipment and subsequent changes in the LME prices through the date of final pricing as gains or losses from a derivative embedded in the sales contract (a futures contract initiated at the date of shipment and settled upon the determination of the "final price"“final price”) which is bifurcated and separately accounted for at fair value. See Note 15.

The host contract is the sale of the metals contained in the concentrates at the then-current LME price as defined in the contract. Mark-to-market price fluctuations recorded through the settlement date are reflected in revenues for sales contracts. Our embedded derivatives at December 31, 2019 and 2018, were not significant to the financial statements.
Revenues from concentrate sales are recorded net of treatment and refining charges. These allowances are a negotiated term of each contract. Treatment and refining charges represent payments or price adjustments to smelters and refiners and are either fixed, or in certain cases, vary with the price of metals (referred to as price participation).





Note 2 - Summary of Significant Accounting Policies - (Continued)

Management estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure

of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The most significant areas requiring the use of management estimates include mineral reserve estimation; useful asset lives for depreciation and amortization; zakat and income taxes; environmental obligations; reclamation and closure costs; estimates of recoverable materials in mill stockpiles; fair value of embedded derivatives; end-of-service indemnities; and asset impairment, including estimates used to derive future cash flows associated with those assets. Actual results could differ from these estimates.

Recent accounting pronouncements
In May 2014 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"). ASU 2014-09 supersedes the revenue recognition requirements of FASB Accounting Standards Codification ("ASC") Topic 605, Revenue Recognition and most industry-specific guidance throughout the Accounting Standards Codification, resulting in the creation of FASB ASC Topic 606, Revenue from Contracts with Customers. ASU 2014-09 requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. For nonpublic companies this ASU provides alternative methods of retrospective adoption and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. Early adoption is permitted. The Company is in its preliminary stages of evaluating the impact of these amendments, although it does not expect the amendments to have a significant impact to the Company's financial position or results of operation. The amendments could potentially impact the accounting procedures and processes over the recognition of certain revenue sources. The Company is expecting to begin developing processes and procedures during 2018 to ensure it is fully compliant with these amendments at the date of adoption.

In November 2015 the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The new standard eliminates the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The Company adopted ASU 2015-17 by classifying its deferred tax assets (liabilities) as noncurrent at December 31, 2017 and 2016.

Note 2 - Summary of Significant Accounting Policies - (Continued)

Recent accounting pronouncements - continued
In February 2016 the FASB issued ASU No. 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). The ASU is effective for fiscal years beginning after December 15, 2019,2020, including interim periods within those fiscal years, with earlier application permitted.  Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption.  The Company has several lease agreements for which the amendments will require the Company to recognize a lease liability to make lease payments and a right-of-use asset which will represent its right to use the underlying asset for the lease term. The Company is currently reviewing the amendments to ensure it is fully compliant by the adoption date and does not expect to early adopt.

As permitted by the amendments, the Company is anticipating electing an accounting policy to not recognize lease assets and lease liabilities for leases with a term of twelve months or less. The Company is currently in the process of fully evaluatingreviewing the amendments to ensure it is fully compliant by the adoption date and will subsequently implement new processes.does not expect to early adopt. In addition, the Company will change its current accounting policies to comply with the amendments with such changes as mentioned above.

Subsequent events
We have evaluated events and transactions subsequent to the date of the financial statements for matters requiring recognition or disclosure in the financial statements. The accompanying financial statements consider events through March 12, 2018,11, 2020, the date on which the financial statements were available to be issued. See Note 10 – Long-term Debt.

Note 3 – Liquidity and Capital Resources

As shown in the financial statements, we have incurred three consecutive years of net losses. Our losses in 2015 were largely attributable to the depressed commodity prices as well as certain operating inefficiencies from the operating contracts with our former operator. In response to these factors, we took certain steps to protecthowever, the Company has operating income and generated cash from operations for the shareholders.  We cancelledlast two years. In addition, we have updated our mineral reserve estimates and extended the operating contracts in 2016 (see Note 8) and suspended operations untillife of the first quarter of 2017.  During our shutdown we renovated our facilities to improve recoveries and reduce costs and prepared to self-operate the facility with the assistance of a Turkish company. 

Note 3 – Liquidity and Capital Resources – (Continued)

During 2017, we strategically ramped up operations gradually through the second quarter.  We had two shipments of ore in 2017 as well as sales of gold and silver. We expect four shipments of ore in 2018. We also expect our operations to be positively impacted by the steady increase of copper and zinc prices which increased over 25% in 2017 compared to 2016.   As noted in Note 10, we did not make our scheduled debt repayments on our outstanding debt.  The Company received correspondence on March 4, 2018 which waived the event of default and deferred the missed payments to 2018. We are currently in negotiations with the SIDF to amend the terms and repayment schedule.

We believe that our continued operations and the itemsadditional debt financing discussed abovein Note 10 will provide us the necessary liquidity and capital resources.  There can be no assurances that our operating assumptions and objectives will be met or that our negotiations with the SIDF will be successful.

Note 15 - Fair Value Measurement

Fair value accounting guidance includes a hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 inputs) and the lowest priority to unobservable inputs (Level 3 inputs).

Level 1Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2Quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that are observable for the asset or liability, or inputs that are derived principally from or corroborated by observable market data by correlation or other means; and

Level 3Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

We did not have any significant transfers in or out of Levels 1, 2, or 3 in 20172019 or 2016.2018. The embedded derivatives in our provisional sales contracts are considered Level 2 measurements.

Note 16 Embedded Derivatives

As described in Note 2 under "Revenue Recognition," our concentrate sales contracts provide for provisional pricing based on the LME price at the time of shipment as specified in the contract.  Sales contracts with a provisional sales price contain an embedded derivative (i.e., the price settlement mechanism that is settled after the time of delivery) that is required to be bifurcated from the host contract. The host contract is the sale of the metals contained in the concentrates at the then-current LME price as defined in the contract. Mark-to-market price fluctuations recorded through the settlement date are reflected in revenues for sales contracts. Our embedded derivatives at December 31, 2017, were not significant to the financial statements.  We had no embedded derivatives at December 31, 2016.
