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

In October 2014 with the completion of the Acquisition, we began operatingWe 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’sSHR'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 17 to the Consolidated Financial Statements for more information.

United States Specialty PetrochemicalPetrochemicals Operations

SHR’sSHR'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 2016 of approximately 48% 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 2015hydrogen supply to the plant. We believe we have sufficient pentane capacity to maintain our share of approximately 84% based upon 7,000 barrels per day.  The Penhex Unit utilization ratemarket growth for 2014 was approximately 84% based upon 6,700 barrels per day.  Penhex Unit capacity is now configured in three independent process units.  The three unit configuration improves reliability by reducing the amount of total down time due to mechanical and other factors.

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.

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 26% for 2016, 27% for 2015, and 36% for 2014.  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 233,000285,000 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 5563 acres of which 2533 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’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’sSHR's facility to:to (1) a natural gas line, (2) SHR’sSHR'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 predominantly Fortune 500large 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.customer's 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 2016See additional discussion of concentration of revenue and 2015, salescorresponding receivables as disclosed in Note 3 to one customer exceeded 10% of our consolidated revenues.  Specifically, in 2016 sales to ExxonMobil and their affiliates represented 20.1% of revenues.  In 2015 sales to ExxonMobil and their affiliates also 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’sSHR'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 70, 70,78, 144, and 7580 barrels were recovered during 2016, 20152019, 2018, and 2014,2017, respectively. The recovered material had an economica value of approximately $3,200, $3,500,$4,100, $5,800, and $6,700$4,200 during 2016, 2015,2019, 2018, and 2014,2017, 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 approximately 310, 296,270, 280, and 271324 for the years ended December 31, 2016, 2015,2019, 2018, and 2014,2017, 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.

1A. Risk Factors.
Investment in AMAK

As of December 31, 2016,2019, we owned a 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’sAMAK'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”"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 (km2)("km2") of territory contiguous to AMAK’sAMAK's current 44 km2km2 mine. The new territory comprises the Guyan and Qatan exploration licenses covering 151 km2,km2, and within the Guyan exploration license, a 10 km2km2 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 1015 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. AMAK took advantage of this outage to improve the gold and silver recovery process through the installation of SART modifications.  This change allows improved precious metal recovery while also lowering chemical use, thereby reducing operating costs once processing resumes.  AMAK also upgraded and refurbished other parts of the facility during the outage; therefore it remains in relatively good condition.  The plant resumed operation in the fourth quarter of 2016 and is scheduled to be at full operating rates, during the second quarter of 2017.

metal recoveries and concentrate quality has continued to improve since.
AMAK shipped approximately 16,000, 51,000,65,000, 58,000, and 55,00028,000 metric tons of copper and zinc concentrate to outside smelters during 2016, 2015,2019, 2018, and 2014,2017, respectively. In addition, in 2014 AMAK initiated operation of its precious metal recovery circuit at the mill

and produced 4.1 kilogramsgold and silver doré intermittently through 2014 and 2015. The precious metals circuit was recommissioned in the fourth quarter of 2017 and produced commercial quantities of gold and 115.6 kilograms of silver.  In 2015, 46.2 kilograms of gold and 833.6 kilograms of silver were produced.  Since the facility was idle until December 2016, no gold or silver was producedbearing doré in 2016.

2018.
Saudi Industrial Development Fund (“SIDF”("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”"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. The SIDF reviewed the current AMAK strategy relatingSee Note 14 to the shutdown, modifications, and improvements and agreed that it was appropriate.Consolidated Financial Statements.image1a05.jpg

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, could adversely impact profitability

During 2016 sales toincluding 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 forthcould materially adversely affect our results 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 other producers of specialty petrochemicals, specialty waxes or other products that can be substituted for our products, which 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 Part I, Item I Business underour 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 positions that could make it increasingly difficult for us to compete in 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 our results of operations, financial condition and cash 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 across which we must allocate our available resources, while competing companies may specialize in only certain of our product lines. As a result, we may invest less in certain areas of our business than our competitors, and such competitors may have greater financial, technical and marketing resources available to them. Industry consolidation may also affect competition by creating larger, more homogeneous and stronger competitors in the caption “United States Specialty Petrochemical Operation”.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 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.
In order to be successful, we must attract, retain and motivate executives and other key employees including those in managerial, technical, safety, sales and marketing positions. We must also keep employees focused on our strategies and goals. The totalfailure to hire, or loss of, key employees in a competitive industry could have a significant adverse impact on our operations. In addition, an important component of our competitive performance is our ability to operate 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 improvements, safe operations, cost control and productivity enhancements. The extent to which we manage these factors will impact our performance relative to competition.
If the availability of our raw materials is limited, we may be unable to produce some of our products in quantities sufficient to meet customer demand or on favorable economic terms, which could have an adverse effect on our results of operations, financial condition 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.

If we are unable to access third-party transportation for our raw materials and finished products, we may not be able to fulfill our obligations to our customers in a timely manner, which could have a material adverse effect on our results of operations, financial condition and cash flows.
We 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. While 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 any other significant disruption in the availability of third-party transportation, we may not be able to obtain 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 obligations to our customers in a timely manner, which 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 volume customerand 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.

Finally, 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 permits 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 marketmeet 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 inherent in chemical manufacturing, storage, handling and transportation. These risks include, but are not limited to, fires, explosions, severe 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 competitive basismaterial adverse effect on our results of operations and generate a profit.financial condition.

Climate changeWhile we adapt our manufacturing and greenhouse gas restrictions

Duedistribution processes and controls to concern overminimize the inherent risk of our operations, to promote workplace safety and to minimize the potential for human error, we cannot completely eliminate the risk of climate change,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 results of operations and financial conditions. Our property, business interruption and casualty insurance may not fully insure us against all potential hazards incidental to our business.
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 industry is subject to extensive laws and evolving regulations related to the protection of the environment. These laws and 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: the discharge of countries have adopted, or are consideringpollutants into the adoption of, regulatory frameworks to reduceenvironment; emissions into the atmosphere (including greenhouse gas emissions. These include adoptionemissions); and restrictions, liabilities and obligations in connection with storage, transportation, treatment and disposal of caphazardous substances and trade regimes, carbon taxes, restrictive permitting, increased efficiency standards,waste. We are also subject to laws and incentivesregulations that require us to operate and maintain our facilities to the satisfaction of applicable regulatory authorities. In addition, failure to comply with these laws or mandates for renewable energy. These requirements could makeregulations, 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 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. Currentservices, or that we are subject to fines, penalties or other interruptions in our operations, our business, results of operations, financial condition and pending greenhouse gas regulationscash flows may also increasebe adversely affected.
If we are not able to continue the technological innovation and successful commercial introduction of new products, our compliance costs, such as for monitoringcustomers may turn to other producers to meet their requirements, which may adversely affect our results of 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, our customers may introduce new generations of their own products, adopt new or sequestering emissions.

Varying economic conditions could adversely impact demand fordifferent 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 metalsapplications 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 and metals correlateshave 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.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 changes 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 and metals.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 varied,been subject to fluctuation, 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.markets. Overall gross margins and profitability in any given period are dependent partially on the product, customer and geographic mix reflected in that period’speriod'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 could result in increased operating costs and reduced demand for our products.
The nature of our operations could make us subject to legislation or regulations affecting the emission of greenhouse gases. The U.S. Environmental Protection Agency has promulgated (and may in the future promulgate) regulations applicable to projects involving greenhouse gas emissions above a certain threshold, and the U.S. and certain states within the U.S. have enacted, or are 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 be made at the international level toward the adoption of international treaties or protocols that would address global greenhouse gas emissions. These limitations may include the adoption of cap and trade regimes, carbon taxes, restrictive permitting, increased efficiency standards and incentives or mandates for renewable energy. Any such 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 legislation, regulation, treaties or protocols may also increase our compliance costs, such as for monitoring or sequestering emissions.

We are exposed to local business risks in different countries, which could have a material adverse effect on our financial condition and results of operations.
Our industriesAlthough we do not have production operations and assets outside of the U.S., we do have a global portfolio of customers and thus we are subject to extensive environmental regulation pursuant to a variety of federalinternational market risks including, but not limited 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 state regulations.  Such environmental legislation imposes, among other things, restrictions, liabilities and obligations in connection with storage, transportation, treatment and disposal of hazardous substances and waste.  Legislation also requires 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.  Failure to comply with these lawsactual or failure to obtain permits may expose us to fines, penaltiesanticipated military or interruptions in operations that could be material to our results of operations.  In addition, some of the finished goods our customers produce, such as expandable polystyrene (EPS), are subject to increasing scrutiny and regulation, which could lead to a reduction in demand for our products.

Safety, business controls, environmental and cyber risk management

Our results depend upon management’s ability to minimize the inherent risks of our operations, to control effectively our business activities and to minimizepolitical conflicts (including the potential for human error.  We apply rigorous management systemsimpact of continued hostilities and continuous focus to workplace safetyconflict in Yemen on the operations of AMAK);
longer accounts receivable cycles and to avoid spillsfinancial instability or credit risk among customers and distributors;
trade regulations and procedures and actions affecting production, pricing and marketing of products, including domestic and foreign customs and tariffs 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 alsotrade barriers;
 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 implementation of a new enterprise resource planning system could cause a financial statement error not to be detected

We are in the process of implementing a new enterprise resource planning (“ERP”) system to replace our current system.  This is a complex process, and the new system will result in changes to our internal controls over financial reporting, including disclosure controls and procedures.  The possibility exists that the migration to the new ERP system could adversely affect the effectiveness of our internal controls over financial reporting.

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 regulations (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 significantly to our operating costs or may significantly limit our business activities. Additionally, our ability to compete in the international market may be adversely affected by non-U.S. governmental regulations favoring or requiring the awarding of leases, concessions and other contracts or exploration licenses to local contractors or requiring foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction.  We are not currently awarelocal jurisdiction;
local labor conditions and regulations and the geographical dispersion of any specific situations of this nature, but there are always opportunities for this type of difficulty to arisethe workforce;
changes in the internationalregulatory or legal environment;
differing technology standards or customer requirements;
import, export or other 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,licensing requirements or loss of, key employees 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 agreementsrequirements 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 ofmaking foreign direct investments, 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 borrowobtain favorable terms for labor and resultraw 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 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 costsother countries by agents or other third-party representatives;
risk of closing an extraordinary transaction andnationalization of private enterprises by foreign governments (including the risk that an announced extraordinary transactionAMAK's mining and exploration leases may not close. As a result, any completed, pendingbe terminated by the Saudi Ministry of Petroleum and Minerals);
foreign currency exchange restrictions and fluctuations;
the outbreak of global or future transactions may contribute to financial results that differ from the investment community’s expectationsregional health epidemics or pandemics;

difficulties associated with repatriating cash generated or held abroad in a given quarter.tax-efficient manner and changes in tax laws; and

Guaranteeing performance by others including third partiesfluctuations in freight costs and 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.

Economic and political instability; terrorist acts; war and other political unrest

The conflict 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."

•     Difficulties associated with repatriating cash generated or held abroad in a tax-efficient manner and changes in tax laws;our business and manage our operations. 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.

Our ability to make payments on and increaseto refinance our costsindebtedness, and expenses. Our operations could beto fund working capital needs and planned capital expenditures, will depend on our ability to generate cash in the future.

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.

Dependence on AMAK management

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 rely upon AMAK’sfrom time to time are subject to contingent liabilities. If any contingent liabilities become actual liabilities, our financial condition may be adversely affected.
We are subject to various contingent liabilities that may affect our liquidity and our ability to meet our obligations, including our limited corporate guarantee to SIDF in connection with AMAK's Loan to fund mining operations. To the extent any of our current or future contingent liabilities become actual liabilities, it may have an adverse effect on our financial condition.
We do 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’sAMAK'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.

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’sAMAK's operating margins and expansion plans

plans.
Cost pressures may continue to occur across the resources industry. As the prices for AMAK’sAMAK'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’sAMAK'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’sAMAK'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.

An impairment of goodwill could negatively impact 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 linecommodities, variation in production costs or businessdifferent recovery rates could result in an impairment.  Accordingly, any determination requiringAMAK's estimated reserves being revised in the write-offfuture.

United States Specialty PetrochemicalPetrochemicals Facility

SHR owns and operates aSHR's specialty petrochemicalpetrochemicals facility nearis located in Silsbee, Texas which is approximately 30 miles north of Beaumont Texas, 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;Reformer Unit; (iii) a Cyclo-pentane Unit; (iv) an Aromax® Unit;Advanced Reformer unit; and (v) an Aromatics Hydrogenation Unit; (vi)Isomerization Unit. 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 11,000 barrels per day of fresh feed. The Reformer Unit, the Advanced Reformer unit, and the Cyclo-Pentane Unit further process streams produced by the Penhex Unit.
In 2015, we constructed and started up D Train, a White Oil Fractionation Unit; (vii)new Penhex production unit 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. During 2018, we constructed a Hydrocarbon Processing Demonstration4,000 barrels per day Advanced Reformer unit to increase our capability to upgrade by-products produced from the PenHex Unit and (viii)to provide security of hydrogen supply to the plant.
In support of the specialty 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 P-Xylene Unit.  Alltruck and railroad loading terminal consisting of these unitsstorage tanks, nine rail spurs, and truck and tank car loading facilities on approximately 63 acres of which 33 acres are currently in operation.

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’sSHR's facility to:to (1) a natural gas line, (2) SHR’sSHR'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.

United States Specialty Polyethylene WaxWaxes Facility

TC owns and operates a specialty synthetic waxwaxes facility from its 27.5 acre plant site located in Pasadena, Texas. After the recent acquisition of the adjacent BASF facility ("B Plant") in 2016 the plant now contains several stainless steel reactors ranging in size from 3,300 to 16,000 gallons with overhead condensing systems, two 4,000 gallon glass line reactors; 5reactors, five Sandvik forming belts with pastillating capabilities, five high vacuum wiped film evaporators varying in size from 12 to 20 m2, steel batch column with 10,000 gallon still pot and 20 theoretical stages of structured packing. TheThis plant also now has the ability to crystallize and recover solids from the crystallization process.  There are also three fully equipped, laboratories onsite.on-site laboratories. With a base product offering of polyethylene waxes, TC is well suited to manage high molecular weight materials that must be managed in the molten state. TC offers pastillating for waxes, polymers and resins, flaking capabilities, as well as solids packaging servicesservices..

In 2017, TC expanded its processing capabilities with the start-up of the hydrogenation/distillation unit. This approximately $29 million investment provides TC with state-of-the-art distillation and high-pressure hydrogenation capabilities. During 2019, TC continued to experience issues with the reliable operation of this unit in accordance with its design specifications. Toward the end of 2019 we completed a number of design corrections and other modifications including changes to operating procedures and operator training in order to improve the unit's operational reliability.
Investment in AMAK

As of December 31, 2016,2019, 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. AMAK took advantage of this outage to improve the gold and silver recovery process through the installation of SART
modifications.  This change allows improved precious metal recovery while also lowering chemical use, thereby reducing operating costs once processing resumes.  The facility resumed operation in the fourth quarter of 2016 and is scheduled to be at full operating rates, during the second quarter of 2017.

metal recoveries and concentrate quality continued to improve steadily since.
AMAK shipped approximately 16,000, 51,000,65,000, 58,000, and 55,00028,000 metric tons of copper and zinc concentrate to outside smelters during 2016, 20152019, 2018 and 2014,2017, respectively. In addition, in 2014 AMAK initiated operation of its precious metal recovery circuit at the mill and produced 4.1 kilogramsgold and silver doré intermittently through 2014 and 2015. The precious metals circuit was recommissioned in fourth quarter of 2017 and produced commercial quantities of gold and 115.6 kilograms of silver.  In 2015, 46.2 kilograms of gold and 833.6 kilograms of silver were produced.  Since the facility was idle until December 2016, no gold or silver was producedbearing doré in 2016.2018.

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.

The mining method used at the project is predominantly long-hole open stoping (LHOS) with backfill, using a 96% mine recovery factor and a stope dilution factor incorporated in the reserve mine plan (as applied to the Mineral Resource model prior to consideration as Mineral Reserves) between 7% and 22% as per geotechnical recommendations (based on the 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 1.01% copper equivalent. Ore reserves were estimated using metal prices of USD $1.13 per pound for zinc, $2.95 per pound for copper, $1,300 per ounce for gold and $18.00 per ounce for 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. Although someSome exploration holes were drilled in both Guyan and Qatan up to 40 years ago, but no reserves are attributablewere attributed to these areas. Exploration activities were restarted in both of these areas during 2016, and results are being evaluated.SRK prepared a

For purposesJoint Ore Reserves Committee ("JORC") compliant report in August 2019 showing approximately (cut-off above 0.80 Au g/tonne) 191,900 ounces at the Jabal Guyan zone excluding other nearby prospects. The diamond drilling program continues at both the Jabal Guyan and Al Aqiq zones, testing depth and extension of calculating proven and probable mineralized materials, a dilution of 5%mineralization with confirmed mineralization intersected at zero grade onan additional 100 meters depth beneath the Saadah zone and 15% at zero grade on the Al Houra and Moyeath zones was assumed. A mining recovery of 80% was used for the Saadah zone and 88% for the Al Houra and Moyeath zones.  Mining dilution is the amount of wallrack adjacent to the ore body that is included in the ore extraction process.  Base case cutoffs used were 5.0% zinc equivalent.  Ore reserves were estimated using metal prices of USD $0.85 per pound for zinc, $2.50 per pound for copper, $800 per ounce for gold and $12.0 per ounce for silver.  Resource estimates are exclusive of reserve estimates.

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 87.7%81% of the copper and 82.6%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 assurancesproject.
AMAK contracted SRK Consulting for a reserve update in 2017, and SRK reported JORC compliant reserves in August 2017. The latest resource estimation has been been updated by AMAK resource geologists in January 2020 based on total of 682 holes and 94,708 meters.

Ore reserves were estimated using metal prices of USD $1.13 per pound for zinc, $2.95 per pound for copper, $1,300 per ounce for gold and $18.00 per ounce for silver.
Mineable (recoverable) reserves include:
24% sidewall dilution in the stope production
0.06Mt 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 effect.pillar (0.6Mt) was excluded from Reserves
Any low grade (CuEq<1.01%) material (0.4Mt) which has to mined out and stored separately
Compared to 2019 MRE, the updated reserves reflect a 1.32M tonnes increase to the MRE, as of January 2020, due to additional drilling at Saadah, Al Houra and Moyeath orebodies. The depth of the three orebodies are not tested yet and underground drilling will continue in 2020 and the coming years to extend the orebody at depth.
Underground access and services to the approximate centre of 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

In the 1994 feasibility study the geologists2019, and engineers stateddevelopment mining on 1366 Level began in early 2020. During 2020, AMAK estimates that there is potential to find more reserves within the Lease area, as the ore zones are all openapproximately 100,000 tonnes will be mined out from Moyeath orebody. A drilling program of 8,000 meters (8 months) has been completed at depth. Further diamond drilling is required to quantify the additional mineralization associated with these zones. An extensive underground and surface diamond drilling exploration program commenced in late 2016.  A significant feature of the Al Masane ore zones is that they tend to have a much greater vertical plunge than strike length; relatively small surface exposures such as the Moyeath, zone maywhich upgraded 1.86M tonnes (proven+probable) class. This will be developed into sizeable ore tonnages by thorough and systematic exploration. Similarly, systematic prospecting of the small surface indicators of mineralizationincluded in the area could yield significant tonnagesmine design and incorporated into the Life of new ore.  Updates toMine schedule. AMAK believes that Moyeath is the feasibility study were completed in 1996, 2005most attractive opportunity for an extended life and July 2009.

An updated reserve study or audit has not been performed overhigher zinc metal recovery through the last three years.  AMAK has contracted with SRK Consulting to provide an update on reserves which is scheduled to be completed during the second quarterLife of 2017.

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’sAMAK'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, and plus or minus tax effected gains or losses on acquisitions.  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 (loss), 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 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.

Certain reclassifications have been madeour 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 Statements of Income for the years ended December 31, 2015, and 2014, in ordersame commitment to conform with the presentation of the year ended December 31, 2016.  These reclassifications had no effectexcellence to our commercial activities where we focus on the previously reported net incomevalue 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 those periods.

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’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 declined during 2016,SHR's specialty petrochemicals sales decreased in 2019 compared to 2018. Product sales revenue decreased 9.9% driven by volume decline of 5.4% and lower 2019 product prices compared to 2018 primarily due to reduced volumes at four significant customers.  Welower 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 20162019 feedstock costs were approximately 20% lower than 2018 reflecting lower crude oil prices. 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 continued the decline which began in the fourth quarter of 2014; however, prices began rising in the third quarter of 2016.  During 2016 average feedstock price fell $0.10 per gallon from 2015’s average but the 2016 year end price was approximately $.03 per gallon higher than 2015 year end.  Typically, when prices start climbing,falling, we experience lowerhigher margins since almost 60% of our selling prices are onas formula pricing which follows market prices calculated upon the prior month.lags feedstock costs. During 2016most of 2019 prime products margins declined as a result of greaterwere assisted due to falling feedstock costs and reduced competitive pricing pressure on someprime products sales that are based on non-formula pricing. Our by-product margins improved significantly compared to 2018 as SHR benefited from a full year of ourreliable operation of the Advanced Reformer unit which upgrades by-products to higher value products.  In addition, financial penalties that
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 incurred dueexpect the remaining proceeds to feedstock purchases below minimum amounts as prescribed by our agreement with suppliers impacted margins.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”("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 nearly 40%
Restructuring and Severance Impact
During 2018, the Company incurred restructuring and severance expenses of $2.3 million which were included in 2016 from 2015 growingGeneral and Administrative Expenses. These expenses were primarily attributable to almost 34the termination of 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 pounds.

Gross Revenue

2015-2016

RevenuesGross revenue for the Specialty Petrochemicals segment decreased from 20152018 to 20162019 by approximately 16.6%10.2% due to a decrease in specialty petrochemicals sales volume of 12.1% and a decrease in average selling price of 7.2% partially offset by an increaseprices. Decline in processing fees of 51.1%.

2014-2015

Revenues decreased from 2014 to 2015 by 23.3% primarily due to a decrease in the average selling price per gallon of 27.1% and a decreasewas primarily attributable to lower feedstock costs in processing fees of 13.7%.2019 which impacts pricing for our formula customers.

PetrochemicalSpecialty Petrochemicals Product Sales

2015-2016

PetrochemicalSpecialty petrochemicals product sales revenue decreased 18.4%9.9% from 20152018 to 20162019 due to a decrease in total sales volume of 12.1%5.4% and a decrease in average selling price of 7.2%4.8%. Much of the decline in sales volume was due to lower by-product sales in 2019 compared to 2018. In 2019, as result of more reliable operation of the Advanced Reformer unit, we processed more by products through the unit resulting in much higher margin upgraded product. The operation of the Advanced Reformer unit results in some volumetric yield loss leading to lower volumes.
Our average selling price decreased primarily because aof lower feedstock costs. A large portion of our prime products sales are contracted with pricing formulas which are tied to prior month Natural Gas Liquid (NGL)Gasoline prices which is our primary feedstock. Our average selling prices for our non-formula priced customers also declined approximately 10.5% primarily due to competitive pressure on pricing.  Average delivered feedstock price for 20162019 was 7.4%20.0% lower than 2015.  We also saw a significant2018 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 margin on byproduct salesprime products. Additionally, although margins for our by-products increased from 20152018 due to 2016.  reliable operation of the Advanced Reformer unit, prices for by-products in 2019 were approximately 7.6% lower than in 2018 due to lower prices for the components in our by-products stream. This also contributed to lower overall selling price.

Prime product sales volume (total petrochemicalspecialty petrochemicals product sales volume less byproductby-product sales volume) decreased 8.8%1.9% or approximately 1.3 million gallons. Excluding sales to the volatile Canadian oil sands market, prime product sales volume growth was approximately 4.4% from 20152018 to 2016 primarily due2019. Sales to lower demand in North America.  Margins on our petrochemical products were also negatively impactedthe Canadian oil sands market continues to be volatile driven by financial penalties that we incurred due to feedstock purchases below minimum amounts as prescribedcontinued manufacturing efficiencies at customer sites and by our agreement with suppliers.

Foreign sales volume accounted for approximately 22.7%23.3% of specialty petrochemicals sales volume and approximately 23.4% of revenue for specialty petrochemicals product sales during 2019 as compared to approximately 25.5% of volume and 26.3%approximately 27.6% of revenue for petrochemicalspecialty petrochemicals product sales during 2016 as compared to 25.2% of2018. The decrease in foreign sales volume and 27.9% of revenue during 2015.

2014-2015

Petrochemical product sales revenue decreased 23.5% from 2014 to 2015was due to a decreaselower demand in the average selling priceCanadian oils sands market. Excluding oil sands, foreign sales volumes in 2019 grew by approximately 8% from 2018.
Processing Fees
Processing fee declined approximately 19.5% from 2018 to 2019 primarily due to the termination of 27.1%.  We saw a significant decline in raw material prices beginningcustomer contract in the fourth quarter of 2014 which continued throughout 2015.  Since our selling prices are based on raw material prices, they declined as well.  Deferred sales volume remained steady from 2014 to 2015; however, deferred sales revenue declined 19.8% due to the decrease in the average selling price.  Prime product sales volume increased 3.1% from 2014 to 2015.

Foreign sales volume accounted for approximately 25.2% of volume and 27.9% of revenue for petrochemical product sales during 2015 as compared to 27.7% of volume and 30.8% of revenue during 2014.

Processing Fees

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.  We were successful in negotiating a contract extension with one of our processing customers whose contract was set to expire in 2016.

2014-2015

Processing fees decreased 13.7% from 2014 to 2015 due to lower run rates being required by our customers.



2018.
Cost of Sales(includes but is not limited to raw materials, total operating expense, natural gas, operating labor and transportation)

2015-2016

Cost of Sales decreased 11.7%17.5% from 20152018 to 2016 primarily2019 due to lower raw material costs, lower operating expense and the decrease in sales volume. Our average delivered feedstock cost per gallon decreased 7.4% over 2015 while volume processed decreased 10.9%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 which is due online in the fourth quarter of 2017, to 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.

2014-2015

Cost of Sales decreased 31.3% from 2014 to 2015 due primarily to a 46.9% decrease in the average cost per gallon of feedstock.  This was offset slightly by higher raw material volumes being processed in order to support the 5.0% increase in sales volume.

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

2015-2016

Total Operating Expense increased 3.3%decreased 1.2% from 20152018 to 2016.  Natural gas,2019 or approximately $0.9 million. The key drivers for the decrease were operating labor depreciation and transportation arecosts, offset by an increase in depreciation. Operating labor costs were lower primarily due to the largest individual expensesreorganization 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 this category; however, not all of these increased.

the third quarter 2018.
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
Labor costs declined 0.2%Gross margin increased from 201510.4% of gross revenue in 2018 to 2016.  Profit sharing distributions were lower and employee headcount decreased17.7% of gross revenue in 2019. This represents an increase of approximately 2.7% from year end 2015 to year end 2016.

Depreciation expense increased 29.9% from 2015 to 2016 primarily due to D Train coming online, and depreciation being recorded on it for a full year.  Higher depreciation expense accounted for approximately 70.1% of the70%. The increase in operating expense.

Transportation costs were lowergross margin was driven by 2.8% primarily due to the decrease in sales volume.

2014-2015

Total Operating Expense increased 3.9% from 2014 to 2015.  Natural gas, labor and transportation are the largest individual expenses in this category; however, not all of these increased.

The cost of natural gas purchased decreased 34.1% from 2014 to 2015 due to a decrease in the average per unit cost and lower volume used.  The average price per MMBTU for 2015 was $2.94 whereas, for 2014 the average per unit cost was $4.49.  Volume consumed decreased to approximately 1,402,000 MMBTU from about 1,417,000 MMBTU.

Operating labor costs were higher by 11.4% mainly due to a cost of living adjustment made at mid-year 2015, additional profit sharing distributions based upon profitability, and an increase in our employee countmargins for the petrochemical segment.  Employee count increased approximately 9.5%both prime products and by-products. Prime product margins benefited from year end 2014 to year end 2015 to support the D Train expansion and in preparation for constructionlower feedstock costs while significant greater reliability of the new reformer unit.

Depreciation expense increased 10.3% from 2014 to 2015 primarily due to D Train coming online in the fourth quarter of 2015.

Transportation costs were higher by 7.2% primarily dueAdvanced Reformer unit contributed to an increase in rail freight which includes car rental.  The number of carsby-product margins. Additionally, operating expenses declined approximately 1.2% or nearly a million dollars thus also helping to increase gross margin in our rail fleet was significant during 2015 in support of our oil sands customer.  As we approached year end, we began trading some of the smaller railcars which were on lease for larger railcars which are more acceptable2019 compared to our customers.  These costs are typically recovered through our selling price.  Higher transportation costs accounted for 82.0% of the increase in operating expense.

2018.
General and Administrative Expense

2015-2016

General and Administrative costs remained stable from 2015 to 2016 with less than a 1% increase.

2014-2015

General and Administrative costs decreased 6.7% from 20142018 to 2015 due primarily to management expenses being recorded at the corporate level instead of at the petrochemical level and a decrease in consulting fees.  During 2014 consulting fees were higher than normal due to costs associated with the Acquisition.

Depreciation

2015-2016

As mentioned above, depreciation expense increased 29.9% from 2015 to 20162019 primarily due to D Train coming online,the absence of restructuring and depreciation being recorded on it for a full year.severance costs incurred in 2018.

2014-2015

Depreciation
Depreciation expense increased 10.3%18.2% or approximately $1.6 million from 20142018 to 20152019 primarily due to D Train coming online during the fourthstart-up of the Advanced Reformer unit in the third quarter of 2015.2018 and the resulting increase of our depreciable base effective for the full year of 2019.

Capital Expenditures

2015-2016

Capital expenditures decreased 5.8%in 2019 declined 69% or approximately $15.5 million from 20152018 primarily due to 2016.the completion of the Advanced Reformer unit. See discussion under “Capital"Capital Resources and Requirements”Requirements" below for more detail.

Product Sales

Product sales revenue increased 31.0%decreased 9.1% and product sales volume increased 39.7%decreased 7.8% from 20152018 to 2016.2019 primarily due to lower PE wax sales. Planned maintenance turnaround at our Pasadena facility in the first quarter of 2019 along with outages at multiple feed suppliers limited our specialty wax production and sales. Polyethylene wax sales saw volume increasesdecreases of approximately 53.8%; however, due to competitive situations, a soft market,11.7% and to minimize finished product inventories, revenue from thesepolyethylene wax decreased approximately 8.0% both as a result of lower sales only increased 12.1%.  In striving to work down wax inventories, we continue to increasevolume and a lower value sales volumes of our low quality wax (which requires significantly less processing and carries a positive gross margin).  As we gain additional approvals of our new, higher quality wax products, we will substitute the low qualitymix. Average wax sales with theseprice was approximately 2.3% higher value products.  We continuein 2019 compared to make good progress in our target markets.   We shipped several orders of our new HMA product as well as, had independent laboratory results showing that our new product performs as well as the leading product in metallocene based HMA applications (in some parameters our product performed better).  Our new powdered PVC lubricant wax has been trialed successfully, and a commercial trial is expected in the first quarter 2017 of molten wax. Other wax based product sales increased2018.
Processing Fees
Processing fees decreased 10.3% from 20152018 to 20162019 primarily due to on-purpose PE wax saleslower revenues from the hydrogenation/distillation unit which has continued to be hampered by operational and reliability issues. In 2019 we distributedimplemented a number of design modifications and changes to operating procedures in Latin America for a third party at lower margins.

TableImpairment of ContentsGoodwill and Certain Intangibles
30We 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 impairment analysis discussed above, we determined the indefinite-lived intangible assets were also impaired as of December 31, 2019. We recorded a non-cash impairment charge of $2.4 million in the fourth quarter of 2019.

Depreciation and Amortization

Depreciation and amortization decreased 14.1%increased 4% from 20152018 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.

General and Administrative Expenses

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 investment in AMAK, the retention of a new internal audit firm, and costs associated with B Plant valuation.

2014-2015

General corporate expenses increased from 20142018 to 20152019 primarily due to increasesincrease in officerexecutive compensation which were re-classed from the petrochemical company, directors’ fees and accounting fees offset by decreases in consulting fees and investor relations expenses.  Directors’ fees increased approximately $0.2 million because of the addition of one director and reassessment of directors’ compensation during 2015.  Accounting fees increased due to costs associated with the Acquisition.  Consulting fees decreased $0.5 million due to the hiring of consultants for the Acquisition during 2014 and investor relations fees decreased $0.1 million due to a change in our investor relations firm.accrual.

Equity in Earnings (Losses) of AMAK/Gain on Equity Issuance of AMAK

2015-2016

Equity in Earnings of AMAK increased 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 investmentInvestment in AMAK stemming from the July 2016 issuance of additional shares to Arab Mining Co.  The settlement and 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).

- Discontinued Operations
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 has begun and the gold extraction is in process.  An extensive exploration program for the rest of Guyan mining lease has been completed.  Results are encouraging and are currently being evaluated.  A systematic program of infill drilling exploration to extend the overall life of the copper and zinc mine has been initiated with detailed results expected in the second quarter of 2017.

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.

AMAK is self-operating the mine and has signed a manpower agreement with a third party that will provide greater technical know-how and required management skills in combination with expected cost savings.

Equity in Losses of AMAK increased 396.7%9.4% from 20142018 to 20152019 due to a number of reasons as discussed below.

AMAK’s performance, like the rest of the mining sector, was severely impacted by the continued fall in metal demand and prices (average spot prices for zinc and copper in fourth quarter 2015 were down approximately 13% and 7%, respectively, compared to third quarter 2015).  The mine also suffered significant raw material outages and operating inefficiencies.

Capital Resources and Requirements

2015-2016

Capital expenditures increased 29.6%decreased 60% from 20152018 to 2016.2019. The majority of the decrease was due to completion of the Advanced Reformer unit. During 20162019 we expended $15.5approximately $2.4 million on upgrades to the hydrogenation/distillation project, $3.9pipeline for GSPL, approximately $0.7 million to purchase and upgrade the BASF facility, $11.6Advanced Reformer unit, $0.5 million related to begin construction on our advanced reformer unit, $1.9 million for tank farm improvements, $1.2 million for high purity hexane production, $0.8 million for cooling tower construction, $0.6 million for transport trucks,a new truck entrance, and $0.5 million for loading rack expansion capabilities, and $4.5 million on various facility improvements and equipment.



2014-2015

Capital expenditures increased 74.1% from 2014 to 2015.  During 2015 we expended $13.3 million on the D Train expansion, $1.8 million on tank farm improvements, $0.6 million on spare equipment, $2.8 on pipeline upgrades, $1.5 million on transportation equipment, $2.2 million on the Oligomerization project (costs fully paid by the customer), $2.1 million on the hydrogenation project, $1.3 million on a wax stripping column, and $5.6 million on various plant improvements and equipment.

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. Early adoption would be permitted but not before annual periods beginning after December 15, 2016. 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 2017 to ensure it is fully compliant with these amendments at the date of adoption.

In April 2015 the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The amendments in this ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU 2015-03. In August 2015 the FASB issued ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting. ASU 2015-15 was issued to address presentation or subsequent measurement of debt issuance costs
related to line-of-credit arrangements that were not found ASU 2015-03.   Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. These standards are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, and should be applied retrospectively. The Company adopted ASU 2015-03 and ASU 2015-15 during 2016.  At December 31, 2016, and 2015, related net loan fees of approximately $0.7 million and $1.0 million, respectively, have been netted against long term debt.

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 will implement ASU 2015-17 by classifying all of it deferred tax assets (liabilities) as noncurrent on its March 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. As permitted by(2) the amendments,hindsight practical expedient when determining lease term and assessing impairment of right-of-use assets. 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 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. For additionalConsolidated Financial Statements for further information on the Company’s leases, see Note 15.

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) classification of excess tax benefits 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 will adopt the amendments as of January 1, 2017, and the Company is currently evaluating the full impact of these amendments. The stock based compensation plan has not historically generated material amounts of excess tax benefits or deficiencies; therefore, the Company does not anticipate a material change in its financial position or results of operation as a result of adopting this Update. The Company is currently implementing the new processes and does not anticipate significant changes. For additional information on the stock-based compensation plan, see Note 16.

In January 2017 the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections Topic 250) and Investments —Equity Method and Joint Ventures (Topic 323). The amendments in the Update relate to SEC paragraphs pursuant to Staff Announcements at the September 22, 2016, and November 17, 2016, EITF meetings related to disclosure ofregarding the impact of recently issued accounting standards. The SEC staff view that a registrant should evaluatethe adoption of ASC updates that have not yet been adopted to determine the appropriate financial disclosures about the potential material effects of the updates842 on the Company's consolidated financial statements when adopted. If a registrant does not know or cannot reasonably estimate the impact of an update, then in addition to making a statement to that effect, the registrant should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact. The staff expects the additional qualitative disclosures to include a description of the effect of the accounting policies expected to be applied compared to current accounting policies. Also, the registrant should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed. The amendments specifically addressed recent ASC amendments to Topic 326, Financial Instruments - Credit Losses, statements.Topic 842, Leases, and Topic 606, Revenue from Contracts with Customers, although, the amendments apply to any subsequent amendments to guidance in the ASC. The Company adopted the amendments in this Update during the
fourth quarter of 2016 and appropriate disclosures have been included in this Note for each recently issued accounting standard.

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’sunit'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 current year, 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 ontesting.
In June 2018, the most recent assessment,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 is unlikely that an impairment amount would need to be calculated; therefore,with 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.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 the Disclosure 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 update. 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 those fiscal years, and the ASU allows for early adoption as of the beginning of an interim or annual reporting period beginning after December 15, 2018. The 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 impact of this ASU will have on its 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 last-in,first-in, first-out method (LIFO)("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
The 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, 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 recognized. 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 2017 the Company recognized revenue according to FASB ASC Topic 605 ("ASC 605"), "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, 2016.

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’sAMAK'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’sAMAK'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’sAMAK's debt is considered an off balance sheet arrangement. Please see further discussion under “Investmentthe heading "Investment in AMAK”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. There are no uncertain income tax positions taken or expected to be taken at January 1, 2007 (adoption date), and at December 31, 2016. See Note 17 to the Notes16 to the Consolidated Financial Statements.

NewOn December 22, 2017, Public Law No. 115-97, also known as, the Tax Cuts and Jobs Act ("TCJA") was enacted. The TCJA included a number of changes to existing U.S. tax laws that impacted the Company, most notably a reduction of the U.S. federal corporate income tax rate from a maximum of 35% to a flat 21% for tax years effective January 1, 2018. The TCJA also implemented a territorial tax system, provided for a one-time deemed repatriation tax on unrepatriated foreign earnings, eliminated the alternative minimum tax ("AMT"), making AMT credit carryforwards refundable, and regulationspermits the acceleration of depreciation for certain assets placed into service after September 27, 2017. In addition the TJCA created 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 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. After 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 could not be determined as wellof December 31, 2019.
The changes to existing U.S. tax laws as new interpretationsa 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 lawsbasis. Deferred tax assets and regulation,liabilities are being proposed or promulgated.  The impactmeasured using enacted tax rates expected to apply to taxable income in the years in which may increase or decreasethose 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 cannot be estimated at this time.

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 in the consolidated statements of income. At December 31, 2016, we had no financial commodity agreements in place.

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 terminates on December 15, 2017.  The notional amount of the interest rate swap was $1.75 million at December 31, 2016.  We receive credit for payments2017. The reduction in the corporate income tax rate resulted in the Company recording $10.3 million benefit from deferred taxes in the year ending December 31, 2017.
Acceleration 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 pay 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 asDepreciation - The Company recognized a cash flow hedge under ASC Topic 815 (see Note 22); however, duereduction to net deferred tax assets attributable to the new debt agreements associated with the Acquisitionaccelerated depreciation for certain assets placed into service after September 27, 2017. This adjustment resulted 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, and the unrealized loss associated with the swapan increase in income tax receivable of approximately $378,000 was recognized$961,000 in the consolidated statement of income.  The fair value of the derivative liability associated with the interest rate swap atyear ending December 31, 2016, and 2015 totaled $0.1 million and $0.2 million, respectively.2017.

We assess 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, 2016, 20152019, 2018 and 2014,2017, we had approximately $84.0$83.9 million, $82.3$103.3 million and $80.5$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 $275,000, $199,000$383,000, $433,000 and $215,000$405,000 at December 31, 2016, 20152019, 2018 and 2014,2017, 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 2016,2019, market risk for 20172020 was estimated as a hypothetical 10% increase in the cost of natural gas and feedstock over the market price prevailing on December 31, 2016.2019. Assuming that 20172020 total petrochemicalspecialty petrochemicals product sales volumes stay at the same rate as 2016,2019, the 10% market risk increase will result in an increase in the cost of natural gas and feedstock of approximately $9.8$12.5 million in fiscal 2017.2020.

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’sSEC'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 not 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’sManagement'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.
·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, 2016,2019, based upon the framework in Internal Control – Integrated Framework (2013) by the Committee of Sponsoring Organizations of the Treadway Commission.  Management’sManagement'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 has determinedconcluded that our internal control over financial reporting was not effective as of December 31, 2016, because of the material weakness described below.2019.
We determined that we did not maintain effective internal control over the accounting for our investment in AMAK. Specifically, controls were not appropriately designed, adequately documented and operating effectively related to the accounting by us for: (1) our equity in earnings of AMAK; and (2) changes in our ownership percentage in AMAK as the result of the sale and issuance of shares of AMAK to other investors.  As a result of this material weakness, we restated our financial statements for the three months ended June 30, 2016 and September 30, 2016, respectively. This control deficiency did not result in any material adjustments to our consolidated financial statements for the year ended December 31, 2016.
A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement our annual or interim financial statements will not be prevented or detected on a timely basis. We have taken steps and plan to take additional measures to remediate the above identified material weakness. Specifically, we are strengthening our controls and procedures regarding our accounting for our investment in AMAK to ensure a complete review of AMAK’s activities are reviewed and considered in the accounting for our investment in AMAK, including all necessary adjustments, related to our investment in AMAK, including, but no limited to, the recognition of its share of AMAK’s earnings and the recognition of changes in our ownership percentage. Additional controls are being implemented to mitigate the associated risks and to support the completeness and accuracy of our financial reporting.
Despite this material weakness, we have concluded that the financial statements included in this report fairly present in all material respects our financial condition, results of operations and cash flows for the periods presented.

(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) Changes in Internal Control over Financial Reporting.

There have been no changes in our internal control over financial reporting during the fourth quarter of 20162019 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.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’sCompany’s internal control over financial reporting based on our audit. 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 audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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

A material weakness is a control deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment.

Management’s failure to apply the appropriate level of review and oversight to the accounting for significant, infrequently occurring transactions such as unusual gains and the additional equity issuance by AMAK, resulted in undetected material adjustments to the Company’s equity investment in the second and third quarter of 2016. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2016 consolidated financial statements, and this report does not affect our report dated March 16, 2017, on those financial statements.

In our opinion, because of the effect of the material weakness described above on the achievement of the objectives of the control criteria, Trecora Resources has not maintained effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets and the related statements of income, comprehensive income, stockholders’ equity, and cash flows of Trecora Resources, and our report dated March 16, 2017, expressed an unqualified opinion.

(“PEVM”), which does not conduct any substantial business activity but owns undeveloped properties in the United States.

The Company’s petrochemicalCompany's specialty petrochemicals operations are primarily conducted through a wholly-owned subsidiary, Texas Oil and Chemical Co. II, Inc. (“TOCCO”("TOCCO"). TOCCO owns all of the capital stock of South Hampton Resources, Inc. (“SHR”("SHR") and Trecora Chemical, Inc. (“TC”("TC"). SHR owns all of the capital stock of Gulf State Pipe Line Company, Inc. (“GSPL”("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’sSHR'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.

On October 1, 2014, TOCCO,2, 2019, we announced that we had entered into a Texas corporation, acquired (“Acquisition”Share Sale and Purchase Agreement (as amended, the “Purchase Agreement”) 100%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.

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, 2016, 2015,2019, 2018, and 2014,2017, originated in the United States. In addition, all of our long-lived assets are in the United States.

Certain reclassifications have been made to the Statements of Income for the years ended December 31, 2015, and 2014, in order to conform with the presentation of the year ended December 31, 2016.  These reclassifications had no effect on the previously reported net income for the years ended December 31, 2015, and 2014.

In addition, certain reclassifications have been made to the Consolidated Balance Sheets for the year ended December 31, 2015, related to our adoption of FASB ASU 2015-03, Interest – Imputation of interest (Subtopic 835-30) and FASB ASU 2015-15, Imputation of interest (Subtopic 835-30) as noted below in Note 13.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation– The consolidated financial statements include the balance sheets, statements of income, comprehensive income, stockholders’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-in, first-out method (LIFO);(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.

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, 2015, and 2014,2017, 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 20152019, 2018 or 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 2014.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, 2016, and 2015, 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, 2016 and 2015.

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 Acquisition.acquisition 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’sfinder'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’sAMAK'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’sAMAK'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, 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.

changes in mineral prices.
Other Assets - Other assets include a license used in petrochemicalspecialty petrochemicals operations, notes receivable,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 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’sasset'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)401(k) plan. We match 100% up to 6% of pay with vesting occurring over 2 years. For years ended December 31, 2016, 2015,2019, 2018, and 2014,2017, matching contributions of approximately $1,195,000, $1,116,000,$1,321,000, $1,502,000, and $641,000,$1,412,000, respectively, were made on behalf of employees.  The significant increase in 2015 was primarily due to the incorporation of TC.

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 $1.0$0.8 million, $0.8 million, and $0.8 million, for 2016, $1.0 million for 2015,2019, 2018, and $1.6 million for 2014.

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, non-vestedunvested 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’sCompany'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, 2016, 20152019, 2018 and 2014,2017, 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, 2016, 2015,2019, 2018, and 20142017 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”"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’sinstrument's fair value are recognized currently in earnings unless specific hedge accounting criteria are met. Special accounting for qualifying hedges allows a derivative instrument’sinstrument'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. AThe Company maintains a valuation

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’smanagement'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.  We recognized no adjustment for unrecognized
On December 22, 2017, Public Law No. 115-97 known as the Tax Cuts and Jobs Act (TCJA) was enacted. The TCJA included 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 benefits.  Asrate from a maximum of December 31, 2016,35 percent to a flat 21 percent for tax years effective January 1, 2018. In addition the TJCA created prospective changes beginning in 2018, including repeal of the domestic manufacturing deduction, acceleration of tax revenue recognition, capitalization of research and 2015, no interest or penalties relateddevelopment expenditures, additional limitations on executive compensation and limitations on the deductibility of interest.
Reclassifications – Certain reclassifications have been made to uncertain tax positions had been accrued.

prior year balances to conform with the current year presentation.
Subsequent Events – The Company has evaluated subsequent events through March 16, 2017,13, 2020, the date that the consolidated financial statements were approved by management. See Notes 6 and 16.

New 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, resultingAdopted 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. Early adoption would be permitted but not before annual periods beginning after December 15, 2016. 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 2017 to ensure it is fully compliant with these amendments at the date of adoption.

In April 2015 the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The amendments in this ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this ASU 2015-03. In August 2015 the FASB issued ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting. ASU 2015-15 was issued to address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements that were not found ASU 2015-03.   Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. These standards are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, and should be applied retrospectively. The Company adopted ASU 2015-03 and ASU 2015-15 during 2016.  At December 31, 2016, and 2015, related net loan fees of approximately $0.7 million and $1.0 million, respectively, have been netted against long term debt.

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 will implement ASU 2015-17 by classifying all of it deferred tax assets (liabilities) as noncurrent on its March 31, 2017, Balance Sheet, see Note 17.

2019
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. For additional information on the Company’s leases, see Note 15.

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 will adopt the amendmentsadopted ASU 842 as of January 1, 2017, and2019, using the Company is currently evaluating the full impact of these amendments. The stock based compensation plan has not historically generated material amounts of excess tax benefits or deficiencies; therefore, the Company does not anticipate a material change in its financial position or results of operation as a result of adopting this Update. The Company is currently implementing the new processes and does not anticipate significant changes. For additional information on the stock-based compensation plan, see Note 16.alternative modified transition method.

In January 2017June 2018, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections2018-07, Topic 250) and Investments —Equity Method and Joint Ventures (Topic 323)Improvements to Nonemployee Share-Based Payment Accounting. The amendments in the Update relate to SEC paragraphs pursuant to Staff Announcements at the September 22, 2016, and November 17, 2016, EITF meetings related to disclosure of the impact of recently issued accounting standards. The SEC staff view that a registrant should evaluate ASC updates that have not yet been adopted to determine the appropriate financial disclosures about the potential material effects of the updates on the financial statements when adopted. If a registrant does not know or cannot reasonably estimate the impact of an update, then in addition to making a statement to that effect, the registrant should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact. The staff expects the additional qualitative disclosures to include a description of the effect ofASU 2018-07 simplifies the accounting policies expectedfor share-based payments to be applied comparednonemployees by aligning it with the accounting for share-based payments to current accounting policies. Also, the registrant should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed. The amendments specifically addressed recent ASC amendments to Topic 326, Financial Instruments - Credit Losses, Topic 842, Leases, and Topic 606, Revenue from Contractsemployees, with Customers, although, the amendments apply to any subsequent amendments to guidance in the ASC.certain exceptions. The Company adopted this ASU on January 1, 2019 and it did not have a material effect on the amendments in this Update during the fourth quarter of 2016 and appropriate disclosures have been included in this Note for each recently issued accounting standard.

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’sunit'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 amendmentsamendment 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 haselected to early adopt this ASU on January 1, 2019. See Note 10 for a discussion of the results of our goodwill from a prior business combinationimpairment testing.
Recent Accounting Pronouncements
In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which is designed to improve the effectiveness of disclosures by removing, modifying and performs an annual impairment test or more frequently if changes or circumstances occur that would more-likely-than-not reduce theadding 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 update. 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 unit below its carrying value. Duringdate 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 current year,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 those fiscal years, and the Company performed its impairment assessment and determined the fair valueASU allows for early adoption as of the aggregatedbeginning of an interim or annual reporting units exceed the carrying value, such that the Company’s goodwill was not considered impaired. Although the Company cannot anticipate future goodwill impairment assessments, based on the most recent assessment, it is unlikely that an impairment amount would need to be calculated; therefore, theperiod beginning after December 15, 2018. The Company does not anticipateexpect the adoption of this ASU to have a materialsignificant impact from theseon 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 toin this update simplify the Company’saccounting 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 impact of this ASU will have on its consolidated 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.

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).

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, 2016,2019, 2018, and 2017, one customer accounted for 20.1%15.0%, 13.5%, and 16.8%, respectively, of petrochemical product revenue.  For the year ended December 31, 2015, one customer accounted for 20.1% of petrochemical product revenue.  For the year ended December 31, 2014, two customers accounted for 23.2% and 10.5% of totalconsolidated revenue. The associated accounts receivable balances for those customersthis customer, ExxonMobil and their affiliates, were approximately $5.1$4.9 million and $11.0 million at December 31, 2016, $7.6 million at December 31, 2015,2019 and $9.5 million and $1.6 million as of December 31, 2014.2018, respectively. The carrying amount of accounts receivable approximates fair value at December 31, 2016.

2019 and 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, 2016, 20152019, 2018, and 2014, petrochemical product sales2017, revenue in foreign jurisdictions accounted for approximately 23.5%21.9%, 26.0%25.5%, and 30.5%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 2016, 2015, and 2014 was 99.4% 100% and 100%, respectively.  At December 31, 2016,2019, and 2015,2018, we owed the supplier approximately $3.7$4.5 million and $2.5$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 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 measuredinvestment in AMAK 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.







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, 2016,2019 and 2015, we had no derivative contracts outstanding.  For additional information see Note 22.2018.

Interest Rate Swaps

In March 2008 we entered intoThe Company committed to a plan to sell our investment in AMAK during the third quarter of 2019. Management engaged in an interest rate swapactive program to market the investment which resulted in an agreement with Bank of America relatedcertain AMAK stockholders in September 2019. Pursuant to the $10.0 million term loan secured by plant, pipelinea Share Sale and equipment.  The interest rate swapPurchase Agreement (the "Purchase Agreement") that was designed to minimize the effect of changes in the LIBOR rate.  We had 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, we believe that the hedge is 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 ineffectiveeffective as of October 1, 2014,2, 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 unrealized loss associated with"Purchasers") for an aggregate gross purchase price (before taxes and transaction expenses) of SAR 264.7 million (or approximately US$70 million), which will be payable in US Dollars. The Purchasers advanced 5% of the swap ofpurchase price (or approximately $378,000 was recognized$3.5 million) in the Statementform of Income fora non-refundable deposit, which was a condition to the year ended December 31, 2014.

We assess the fair valueeffectiveness of the interest rate swap usingPurchase Agreement. These advances were recorded as a present value model that includes quoted LIBOR ratesreduction in our investment in AMAK.
The Purchase 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.

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.

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, 20162019 and 2015:2018, 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 difference between the calculated value of inventory under the FIFO and LIFO bases generates either a recorded LIFO reserve (i.e., where FIFO value exceeds the LIFO value) or an unrecorded negative LIFO reserve (i.e., where the LIFO value exceeds the FIFO value).  In the latter case, in order to ensure that inventory is reported at the lower of cost or market and in accordance with ASC 330-10, we do not increase the stated value of our inventory to the LIFO value.
At December 31, 2016 and 2015, the LIFO value of 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, 2016,2019 and 2015,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.

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, 2016, and 2015, we had a non-controlling equity interest of approximately $49.4 million and $47.7 million, respectively.

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:

Equity in loss of AMAK $(1,479) $(5,325) $(1,072)

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.

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, 2016:

NamePercentage Owned
Various Saudi shareholders46.73%
Trecora Resources33.44%
Armico19.51%
Treasury0.32%
Total100.00%

At December 31, 2016, we had a receivable from AMAK of approximately $14,000 relating to unreimbursed travel expenses.

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 2016, 2015, or 2014.

In addition, we had approximately $31.0$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 available tolimited by, and in the future may be drawn.  However, in orderlimited by our obligation to maintain compliance with ourthe covenants we could have only drawn approximately $29.5 million.

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:

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.

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 through June 2019.  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, 2016, and 2015 was 310.0 million Saudi Riyals (US$82.7 million).

On July 17, 2016, we, along with some existing shareholders of AMAK, executed a document in favor of the Chairman of AMAK agreeing to provide a stock bonus to him upon successful completion of financial and operational goals.  We will contribute 250,000 shares of our AMAK stock and other shareholders will also contribute 250,000 shares for the award upon his success in reaching the goals by the end of 2017.

Operating Lease Commitments

We have operating leases for the rental of over 340 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 $21.2 million over the next 10 years.

We also have an operating lease for our office space in Sugar Land, TX.  The expiration date for this lease is 2018.  The total amount of the commitment is approximately $0.1 million.  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 approximately $0.1 million.

Future minimum property and equipment lease payments under the non-cancelable operating leases at December 31, 2016, are as follows:

Year Ending December 31, Long-Term Debt 
  (thousands of dollars) 
2017 $3,595

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.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 ("TCJA") was signed into law making significant changes to the Internal Revenue Code. The changes as a result of the TCJA, which had 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. The provisional estimate was finalized including consideration of TCJA on long term construction projects.
The Company 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. 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:

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 establishedevaluating the overall presentation of the financial statements. We believe that our audits provide a “hedge committee”reasonable basis for derivative oversight.our opinion.

We endeavor to acquire feedstock and natural gas athave served as 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.
The following tables detail (in thousands) the impact the feedstock and natural gas instruments had on the financial statements:

Interest Rate SwapsRiyadh, Kingdom of Saudi Arabia
March 11, 2019

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 (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 terminates on December 15, 2017.  The notional amount of the interest rate swap was $1.75 million at December 31, 2016.  We receive 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 pay 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.

Due to the new debt agreements associated with the Acquisition, we believe that the hedge is 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, and the unrealized loss associated with the swap of approximately $378,000 was recognized in the Statement of Income.AL MASANE AL KOBRA MINING COMPANY

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 $918,000 based upon an annuity single premium value contract was outstanding at December 31, 2016, and was included in post-retirement benefits.  Mr. El Khalidi retired effective June 30, 2009.  As of December 31, 2016, 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, 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 $265,000 was outstanding at December 31, 2016, and included in post-retirement benefits.  For the period ended December 31, 2016, and 2015, approximately $12,000 and $6,000, respectively had been paid.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and
Shareholders of Al Masane Al Kobra Mining Company
Najran, Kingdom of Saudi Arabia

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, 2016Commerce and 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 of operations, changes in shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2016. The Company’s management is responsible for these financial statements. Our responsibility is“Company” are intended to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position ofmean 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 aswas 450,000,000 consisting of December 31, 201645 million shares of 10 each of which 50% were issued for cash. The remaining 50% were issued for the contribution of mining rights and 2015,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 resultsministry 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 operationsauthorized 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 cash flowsauthorized 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 SR780,000,000 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 2018, the Company increased share premium by SR2,453,580 for shares that were previously issued.
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 yearsCompany (collectively, the “Purchasers”) entered into a Share Sale and Purchase Agreement (“Purchase Agreement”) with Trecora to purchase their entire equity interest in the three-year periodCompany 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, 2016 in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 3 to the financial statements, management believes the cash generated from recommencing operations in 2017, increased efficiencies from our operational improvements and possible additional equity issuances from existing and new shareholders will provide any necessary liquidity and capital resources. In addition, As discussed in Note 8 to the financial statements, the Company recorded a gain of approximately SR65,345,000 from forgiveness of liabilities from their former mine operator China National Geological & Mining Corp. and subcontractor Nesma & Partners Contracting Co., Ltd.  Our opinion is not modified with respect to these matters.2019.

Notes to Financial Statements




Note 1 – Organization and Business

Organization
Al Masane Al Kobra Mining Company is a Saudi Arabian closed joint stock company approved by the Minister of Commerce and 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 “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.

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.  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 fourth quarter of 2016 and have four scheduled shipments of ore in 2017.

Note 1 – Organization and Business – (Continued)

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.  A systematic program of infill drilling exploration to extend the overall life of the copper and zinc mine has been initiated with detailed results expected in the second quarter of 2017.


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, 2016, 2015,2019, 2018, and 2014,2017, 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, 2016, 2015,2019, 2018, and 2014.2017. In addition, we determined that an allowance for doubtful accounts was not necessary at December 31, 20162019 and 2015.  Due to the shutdown of operations, we had no outstanding accounts receivable at December 31, 2016.



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

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, 2016, 20152019, 2018 and 2014.

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)

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, 2016, 2015,2019, 2018 and 2014.

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 linestraight-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, 2016, we had no outstanding capital lease obligations.

Operating lease expense amounted to approximately SR442,000, SR696,000,SR4,015,000, SR1,619,000 and SR867,000SR1,454,000 for the years ended December 31, 2016, 20152019, 2018 and 2014,2017, 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.

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’s carrying value and are depreciated (primarily on a unit-of-production basis) over the asset’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 2009 to 2014 are currently under review with GAZT.

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, 2015, related to our adoption of FASB ASU 2015-03, Interest – Imputation of interest (Subtopic 835-30) and FASB ASU 2015-15, Imputation of interest (Subtopic 835-30) as noted below in Notes 2 and 11.





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

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” priced at the time of shipment. The provisional price received at the time of shipment is later adjusted to a “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”) which is bifurcated and separately accounted for at fair value. See Note 18.

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).

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. 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. Early adoption would be permitted but not before annual periods beginning after December 15, 2016. 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 2017 to ensure it is fully compliant with these amendments at the date of adoption.

In April 2015 the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The amendments in this ASU 2015-03 require that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance  costs are not affected by the amendments in this ASU 2015-03. In August 2015 the FASB issued ASU No. 2015-15, Interest - Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting. ASU 2015-15 was issued to address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements that were not found ASU 2015-03.   Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. These standards are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, and should be applied retrospectively. The Company adopted ASU 2015-03 and ASU.
Note 2 - Summary of Significant Accounting Policies - (Continued)

2015-15 during 2016.  At December 31, 2016, and 2015, related net loan fees of approximately SR12,527,000 million and SR14,676,000, respectively, have been netted against long term debt.

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 will implement ASU 2015-17 by classifying its deferred tax assets (liabilities) as noncurrent on its March 31, 2017, Balance Sheet as applicable.

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, 2018,2020, 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 10, 2017,11, 2020, the date on which the financial statements were available to be issued.

Note 3 – Liquidity and Capital Resources

As shown in the financial statements, we have incurred three consecutive years of net losses however, the Company has operating income and had a negative margingenerated cash from operations in 2016 and 2015. Our losses were largely attributable tofor the depressed commodity prices as well as certain operating inefficiencies from the operating contracts in effect with our former operator.last two years. In response to these factors, we took certain steps to protect the Company and the shareholders. We renegotiated our debt repayment arrangement with SIDF and postponed any repayments until 2017. We cancelled the operating contracts (see Note 8) and suspended operations until the fourth quarter of 2016. In February 2016, we entered into a new operating and rehabilitation contract with a different provider under more favorable terms. During our shutdown we renovated our facilities to improve recoveries and reduce costs and will self-operate the facility with the assistance of a Turkish company which is expected to improve profitability.  Finally, we issued an additional 3,750,000 shares in July 2016 at a price of SR20 to ensure that adequate cash was available during the renovation.  The facility restarted in December 2016 andaddition, we have four planned shipmentsupdated our mineral reserve estimates and extended the life of ore in 2017.

the mine. 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.  If they are not met, we may experience liquidity problems.

On March 31, 2016, the Company entered into finalization and discharge memorandums of understanding (MOU’s) with their former mine operator CGM and subcontractor Nesma where certain contracts were cancelled.  These contracts include the EPC Surface Works Contract and Subcontract (CGM/NESMA) dated November 26, 2007, the Underground Mining Contract (CGM) dated June 29, 2010, the 1st Surface Works O&M Contract (CGM) dated July 3, 2011, and the 2nd Surface Works O&M Contract (CGM) dated November 3, 2014 (collectively, the Contracts).  The MOU’s are binding agreements between the Company, CGM and Nesma.  All of CGM’s spare parts on site related to the Contracts shall revert to and become the property of the Company.  CGM received payment of approximately SR4,500,000 and forfeited their rights to the spare parts that had an economic value of approximately SR34,477500.  The spare parts were recorded at SR4,500,000 and included in property and equipment, net on the balance sheets. Under the MoU’s, CGM and Nesma shall not receive any further payments from the Company as full settlement against the deterioration of property, plant and equipment which exceeds normal wear and tear and any other breach of contracts.    In recognition of certain financial losses incurred by the Company, CGM and NESMA agreed to forfeit the recovery of all remaining amounts due under the Contracts. The total amounts of liabilities recorded on the Company’s books as of March 31, 2016 were approximately SR65,345,000 which were written off to other income on the statement of operations for the year ended December 31, 2016.  There are no outstanding or unresolved claims and all parties have fulfilled their obligations in connection with the Contracts.

Note 9 – Pre-export Advance Payments

We received 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, 2016.  We had an outstanding advance liability of approximately SR9,151,000 at December 31, 2015.

Note 17 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. We had no embedded derivatives at December 31, 2016.  Our embedded derivatives at December 31, 2015, were not significant to the financial statements.


Note 1815 - 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 20162019 or 2015.2018. The embedded derivatives in our provisional sales contracts are considered Level 2 measurements.
