Business Segments

In October 2014 with the completion of the Acquisition, we began operating
Business Segments
We operate in two business segments; the manufacturing of various specialty petrochemical products and the manufacturing of specialty synthetic waxes.

Our specialty petrochemical products segment is conducted through SHR, a Texas corporation. SHR owns and operates a specialty petrochemical facility near Silsbee, Texas which produces high purity hydrocarbons and other petroleum based products including isopentane, normal pentane, isohexane and hexane which may behexane. 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 specialty petrochemical products are typically transported to customers by rail car, tank truck, iso-container, and on occasion 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.
Our specialty synthetic wax 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 Petrochemical Operations

SHR’sSHR's specialty petrochemical facility is located in Silsbee, Texas approximately 30 miles north of Beaumont and 90 miles east of Houston. The facility consists of eight 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; (v) an Aromatics
1

Hydrogenation Unit; (vi) a White Oil Fractionation Unit; (vii) a Hydrocarbon Processing Demonstration UnitUnit; and (viii) a P-Xylene Unit. All of these units are currently in operation.

The Penhex Unit including the new D-train unit, currently has the permitted capacity to process approximately 11,000 barrels per day of fresh feed with the Reformingfeed. 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 capacitywas taken out of approximately 400 barrels per day,service and decommissioned in 2018 with the start up of the new Advanced Reformer unit. 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.

We believe we are positioned to benefit from capital investments that we have recently completed. We now have sufficient pentane capacity to maintain our share of market growth for the foreseeable future. We believe that the Advanced Reformer unit will contribute to increased revenue and gross margin over time and as we improve reliability. While petrochemical prices are volatile on a short-term basis, and volumes depend on the demand of our customers' products and overall customer efficiency, our investment decisions are based on our long-term business strategy and outlook.
During 2015, we constructed a new unit which is part of the Penhex Unit, D-train,D Train, which began production in the fourth quarter providing additionalof 2015. The D Train expansion increased our capacity ofby approximately 4,0006,000 barrels per day.  Going forwardday of fresh feed. Our present total capacity utilization will be based uponis 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 4,000 barrels per day Advanced Reformer unit to increase our capability to upgrade byproducts produced from the PenHex Unit and to provide security of hydrogen supply to the plant.
Products from the Penhex Unit, Reformer Unit, Aromax® Unit,Advanced Reformer unit, and Cyclo-pentane Unit are marketed directly to the customer by our marketing personnel. The Penhex Unit had a utilization rate during 20152018 of approximately 84%56% based upon 7,00011,000 barrels per day.day of capacity. The Penhex Unit had a utilization rate for 2014 and 2013 wasduring 2017 of approximately 84% and 70%, respectively,53% based upon 6,70011,000 barrels per day of capacity. The Penhex Unit had a utilization rate during 2016 of approximately 48% based upon 11,000 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.

This configuration also allows us to use spare capacity for new product development. The Advanced Reformer and Aromax® UnitsReformer 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-coking and other mechanical repairs.

In February 2018, while attempting to commission the new Advanced Reformer unit, the unit overheated and ignited a fire. There was damage to all six heaters in the unit, and the damaged equipment had to be replaced. The Aromatics Hydrogenationtotal repair cost was approximately $3.5 million. Our insurers covered costs over our $1 million deductible. On July 9, 2018, we announced the safe and successful start up of the Advanced Reformer unit. In mid-September 2018 the Silsbee facility suffered a power outage causing a shutdown of the plant, including the Advanced Reformer unit. In October 2018, after extensive engineering review and consultations with the technology licensor of the Unit White Oils Fractionationit was determined that the unit's catalyst required replacement. We completed the catalyst replacement and successfully restarted the Unit Hydrocarbon Processing Demonstration Unit and P-Xylene Unit are operated as independent and completely segregated processes.  These units are dedicatedin December 2018. The cost of the catalyst replacement was approximately $3 million. During the time the Advanced Reformer unit was not operation due to the needscatalyst replacement work, we incurred losses as a result of three different toll processing customers.  The customers supply and maintain title tosales of byproducts at prices well below 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 capacitycost of approximately 3,400 barrels per day. Together they realized a utilization rate of 27% for 2015, 36% for 2014, and 42% for 2013.  The units are operated in accordance with customer needs, and the contracts call for take or pay minimums of production.feedstock.

In support of the specialty petrochemical 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 our feedstock requirements from a sole supplier.  The agreement is primarily a logistics convenience.  The supplier buys or contracts for material only with SHR’s approval 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 cancelled by either party with 180 days’ notice.  In 2015 a pipeline connection to the supplier’s dock was added to give alternative means of receiving feedstock.  Prior to this addition, all feedstock came from Mont Belvieu, Texas.

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

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 an internet presence.a website with information about our products and services. We have adopted a strategy of moving our larger volume customers toutilize both formula and non-formula based pricing to reduce the effect of feedstock cost volatility.depending upon a customer's requirements. 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. We believe that the use of formula pricing helps reduce volatilityDuring 2018 and increase predictability of product margins.  However, we continue to investigate alternative product pricing methods.  During 2015 and 2014,2017, sales to one customer and two customers, respectively exceeded 10% of our consolidated revenues. Specifically, in 2015During 2018 and 2017, sales to ExxonMobil and their affiliates represented 20.1%were 17% and 20% of revenues.  In 2014 sales to ExxonMobil and their affiliates represented 23.2% oftotal revenues, and sales to Tricon Energy represented 10.5%.  In both cases theserespectively. These sales represented multiple products sold to multiple facilities.  We believe that we should be able to place volumes lost to one particular customer with another customer without significantly impacting our operation.

United States Mineral Interests

Our only mineral interest in the United States is our 55% ownership interest in an inactive corporation, PEVM. PEVM’sPEVM's properties include 48 patented and 5 unpatented claims totaling approximately 1,500 acres. All of the claims are located in Lincoln County, NV.

At this time, neither we nor PEVM have plans to develop the mining assets near Pioche, NV. Periodically proposals are received from outside parties who are interested in developing or using certain assets. We do not anticipate making any significant domestic mining capital expenditures.

Environmental

General. Our operations are subjectMatters pertaining to stringent and complex federal, state, local and foreign laws and regulations relating to release of hazardous substances or wastes into the environment or otherwise relating to protectionare discussed in Part I, Item 1A. Risk Factors, Part II, Item 7. Management's Discussion and Analysis of the environment. As with the industry generally, compliance with existingFinancial Condition and anticipated environmental lawsResults of Operations and
3

regulations increases our overall costs of doing business, including costs of planning, constructing, Notes 2 and operating plants, pipelines, and other facilities. Included in our construction and operation costs are capital cost items necessary to maintain or upgrade equipment and facilities. Similar costs are likely upon changes in laws or regulations and upon any future acquisition of operating assets.

Any failure to comply with applicable environmental laws and regulations, including those relating to equipment failures and obtaining required governmental approvals, may result in the assessment of administrative, civil or criminal penalties, imposition of investigatory or remedial activities and, in less common circumstances, issuance of
injunctions or construction bans or delays. We believe that we currently hold all material governmental approvals required to operate our major facilities. As part of the regular overall evaluation of our operations, we have implemented procedures to review and update governmental approvals as necessary. We believe that our operations and facilities are in substantial compliance with applicable environmental laws and regulations and that the cost of compliance with such laws and regulations currently in effect will not have a material adverse effect on our operating results or financial condition.

The clear trend in environmental regulation is to place more restrictions and limitations on activities that may affect the environment, and thus there can be no assurance as14 to the amount or timing of future expenditures for environmental compliance or remediation, and actual future expenditures may be different from the amounts we currently anticipate. Moreover, risks of process upsets, accidental releases, or spills are associated with our possible future operations, and we cannot assure you that we will not incur significant costs and liabilities, including those relating to claims for damage to property and persons as a result of any such upsets, releases, or spills. In the event of future increases in environmental costs, we may be unable to pass on those cost increases to customers. A discharge of hazardous substances or wastes into the environment could, to the extent losses related to the event are not insured, subject us to substantial expense, including both the cost to comply with applicable laws and regulations and to pay fines or penalties that may be assessed and the cost related to claims made by neighboring landowners and other third parties for personal injury or damage to natural resources or property. We will attempt to anticipate future regulatory requirements that might be imposed and plan accordingly to comply with changing environmental laws and regulations and to minimize costs with respect to more stringent future laws and regulations of more rigorous enforcement of existing laws and regulations.Consolidated Financial Statements.

Hazardous Substance and Waste. To a large extent, the environmental laws and regulations affecting our operations relate to the release of hazardous substances or solid wastes into soils, groundwater and surface water, and include measures to prevent and control pollution. These laws and regulations generally regulate the generation, storage, treatment, transportation and disposal of solid and hazardous wastes, and may require investigatory and corrective actions at facilities where such waste may have been released or disposed. For instance, the Comprehensive Environmental Response, Compensation and Liability Act, or CERCLA, also known as the “Superfund” law, and comparable state laws, impose liability without regard to fault or the legality of the original conduct, on certain classes of persons that contributed to a release of “hazardous substance” into the environment. Potentially liable persons include the owner or operator of the site where a release occurred and companies that disposed or arranged for the disposal of the hazardous substances found at the site. Under CERCLA, these persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources, and for the costs of certain health studies. CERCLA also authorizes the EPA and, in some cases, third parties to take actions in response to threats to the public health or the environment and to seek to recover from the potentially responsible classes of persons the costs they incur. We have not received any notification that we may be potentially responsible for cleanup costs under CERCLA or any analogous federal or state laws, except as expressly provided herein.

We also generate, and may in the future generate, both hazardous and nonhazardous solid wastes that are subject to requirements of the federal Resource Conservation and Recovery Act, or RCRA, and/or comparable state statutes. From time to time, the Environmental Protection Agency, or EPA, and state regulatory agencies have considered the adoption of stricter disposal standards for nonhazardous wastes, including crude oil and natural gas wastes. Moreover, it is possible that some wastes generated by us that are currently classified as nonhazardous may in the future be designated as “hazardous wastes,” resulting in the wastes being subject to more rigorous and costly management and disposal requirements.

Air Emissions. Our current and future operations are subject to the federal Clean Air Act and comparable state laws and regulations. These laws and regulations regulate emissions of air pollutants from various industrial sources, including our facilities, and impose various monitoring and reporting requirements. Pursuant to these laws and
4

regulations, we may be required to obtain environmental agency pre-approval for the construction or modification of certain projects or facilities expected to produce air emissions or result in an increase in existing air emissions, obtain and comply with the terms of air permits, which include various emission and operational limitations, or use specific emission control technologies to limit emissions. We will likely be required to incur certain capital expenditures in the future for air pollution control equipment in connection with maintaining or obtaining governmental approvals addressing air-emission related issues. Failure to comply with applicable air statutes or regulations may lead to the assessment of administrative, civil or criminal penalties, and may result in the limitation or cessation of construction or operation of certain air emission sources.

Climate Change. In response to concerns suggesting that emissions of certain gases, commonly referred to as “greenhouse gases” (including carbon dioxide and methane), may be contributing to warming of the Earth’s atmosphere, the U.S. Congress is actively considering legislation to reduce such emissions. In addition, at least one-third of the states, either individually or through multi-state regional initiatives, have already taken legal measures intended to reduce greenhouse gas emissions, primarily through the planned development of greenhouse gas emission inventories and/or greenhouse gas cap and trade programs. In addition, EPA is taking steps that would result in the regulation of greenhouse gases as pollutants under the federal Clean Air Act. Furthermore, in September 2009 the EPA finalized regulations that require monitoring and reporting of greenhouse gas emissions on an annual basis including extensive greenhouse gas monitoring and reporting requirements beginning in 2010. Although the greenhouse gas reporting rule does not control greenhouse gas emission levels from any facilities, it will still cause us to incur monitoring and reporting costs for emissions that are subject to the rule. Some of our facilities include source categories that are subject to the greenhouse gas reporting requirements included in the final rule. In December 2009 the EPA also issued findings that greenhouse gases in the atmosphere endanger public health and welfare and emissions from mobile sources cause or contribute to greenhouse gases in the atmosphere. The endangerment findings will not immediately affect our operations, but standards eventually promulgated pursuant to these findings could affect our operations and ability to obtain air permits for new or modified facilities. Legislation and regulations relating to control or reporting of greenhouse gas emissions are also in various stages of discussions or implementation in about one-third of the states. Lawsuits have been filed seeking to force the federal government to regulate greenhouse gases emissions under the Clean Air Act and to require individual companies to reduce greenhouse gas emissions from their operations. These and other lawsuits may result in decisions by state and federal courts and agencies that could impact our operations and ability to obtain certifications and permits to construct future projects.

Passage of climate change legislation or other federal or state legislative or regulatory initiatives that regulate or restrict emissions of greenhouse gases in areas in which we conduct business could adversely affect the demand for the products we store, transport, and process, and depending on the particular program adopted, could increase the costs of our operations including costs to operate and maintain our facilities, install new emission controls on our facilities, acquire allowances to authorize our greenhouse gas emissions, pay any taxes related to our greenhouse gas emissions and/or administer and manage a greenhouse gas emissions program. We may be unable to recover any such lost revenues or increase costs in the rates we charge customers, and any such recovery may depend on events beyond our control. Reductions in our revenues or increases in our expenses as a result of climate control initiatives could have adverse effects on our business, financial position, results of operations and prospects.

Clean Water Act. The Federal Water Pollution Control Act, also known as the Clean Water Act, and comparable state laws impose restrictions and strict controls regarding the discharge of pollutants, including natural gas liquid related wastes, into state waters or waters of the United States. Regulations promulgated pursuant to these laws require that entities that discharge into Federal and state waters obtain National Pollutant Discharge Elimination System, or NPDES, and/or state permits authorizing these discharges. The Clean Water Act and analogous state laws assess administrative, civil and criminal penalties for discharges of unauthorized pollutants into the water and impose substantial liability for the costs of removing spills from such waters. In addition, the Clean Water Act and analogous state laws require that individual permits or coverage under general permits be obtained by covered facilities for discharges of storm water runoff.

TCEQ.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
5

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. 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, 75,144, 80, and 7170 barrels were recovered during 2015, 20142018, 2017, and 2013,2016, respectively. The recovered material had an economica value of approximately $3,500, $6,700,$5,800, $4,200, and $7,000$3,200 during 2015, 20142018, 2017, and 2013,2016, 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 $0.9 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.

The Clean Air Act Amendments of 1990. The Clean Air Act Amendments of 1990 had a positive effect on our business as manufacturers search for ways to use more environmentally acceptable materials in their processes. There is a current trend among manufacturers toward the use of lighter and more recoverable C5 hydrocarbons (pentanes) which comprise a large part of our product line. We believe our ability to manufacture high quality solvents in the C5 hydrocarbon market will provide a basis for growth over the coming years.   Also, as the use of C6 hydrocarbons (hexanes) is phased out in parts of the industry, several manufacturers of such hydrocarbons have opted to no longer market those products.  As the number of producers has consolidated, we have increased our market share at higher sales prices from customers who still require C6 hydrocarbons in their business.

Personnel

The number of our regular, U.S. Basedbased employees was approximately 296, 271,280, 324, and 166310 for the years ended December 31, 2015, 20142018, 2017, and 2013,2016, 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. The significant increase during 2014 wasOur workforce has decreased primarily due to the Acquisition and D-train construction personnel needs.completion of capital projects at our facilities including a workforce downsizing at SHR in December 2018.

Competition

The specialty petrochemical, specialty wax, 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, 2015,2018, we owned a 35%33.4% 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 about 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; and since the facility was constructed new at that time, it remains in relatively good condition.  Total cost to date is approximately USD $320 million.  AMAK plans to spend approximately $10 million on plant refurbishment and upgrades during 2016 with little beyond this since any new reserves will be processed at the same facility.

AMAK commenced commercial operation in July 2012. AMAK shipped approximately 51,000, 55,000 and 72,000 metric tons of copper and zinc concentrate to outside smelters during 2015, 2014 and 2013, respectively.  In addition, in 2014 AMAK initiated operation of its precious metal recovery circuit at the mill and produced 4.1 kilograms of gold and 115.6 kilograms of silver.  In 2015, 46.2 kilograms of gold and 833.6 kilograms of silver were produced.

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 to the point of being profitable even at current, low commodity prices.  AMAK is taking advantage of this outage to improve the gold and silver recovery process through the installation of SART modifications.  This change will allow improved precious metal recovery while also lowering chemical use, thereby reducing operating costs once processing resumes.  Precious metal recovery can continue even during the shutdown depending on labor availability.operations. The facility is expected to resumeplant resumed operation in the fourth quarter of 2016.2016 and operating rates, metal recoveries and concentrate quality has continued to improve throughout 2017 and 2018.
AMAK shipped approximately 58,000, 28,000, and 16,000 metric tons of copper and zinc concentrate to outside smelters during 2018, 2017, and 2016, respectively. In 2014 AMAK initiated operation of its precious metal recovery circuit at the mill and produced gold and silver doré intermittently through 2014 and 2015. The precious metals circuit was recommissioned in the fourth quarter of 2017 and produced commercial quantities of gold and silver bearing doré in 2018.

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

On October 24, 2010, we executed a limited guarantee in favor of the SIDF guarantyingguaranteeing 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.image1a04.jpg

Item 1A.   Risk Factors.

Our financial and operating resultsWe are subject to a variety of risks inherent in the global specialty petrochemical, specialty wax 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.  We discuss some of these risks in more detail below in no particular order of priority.

DependenceWe rely on a limited number of customers, including one customer that represented more than 10% of our consolidated revenue in 2018. A significant change in customer relationships or in customer demand for our products could materially adversely impact profitabilityaffect our results of operations, financial position and cash flows.

During 2015 sales to one customer exceeded 10 percent of SHR’s revenues.  See the information regarding dependenceWe rely on a limited number of customers. Our largest customer, ExxonMobil and its affiliates, represented approximately 17.0% of our consolidated revenues in 2018. A significant reduction in sales to any of our other key customers set forthcould materially adversely affect our results of operations, financial position 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 position 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 large volume customercompetitive 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.


We do not control the activities of AMAK and are dependent on AMAK's management and board of directors.

Although we believe that we have influence over the operating and financial policies of AMAK, we do not control AMAK's activities. The extent to which we are able to influence specific operating and financial decisions depends on our ability to persuade other AMAK board members and management regarding these policies. Our ability to persuade them may be adversely affected by cultural differences, differing accounting and management practices and differing governmental laws and regulations. In addition, we rely upon AMAK's management and board of directors to direct the operations of AMAK, including employing various engineering and financial advisors to assist in the development and evaluation of the mining projects in Saudi Arabia. We also rely on management of AMAK to provide timely, accurate financial information required for inclusion with our reports filed with the SEC.

There can be no assurance that our investment in 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.

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 meet product demand, which could adversely impact our business, results of operations, financial condition and cash flows.

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 also has financial covenants that require TOCCO to maintain a maximum 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 Financial Condition and Results of Operations-Liquidity and Capital Resources-Credit Agreement.

A failure by us or our subsidiaries to comply with the covenants and restrictions contained in the agreements governing our indebtedness could result in an event of default under such indebtedness, which could adversely affect our ability to market products on a competitive basisrespond to changes in our business and generate a profit.manage our operations. Upon the occurrence of an event of default under any of the agreements

Climate changegoverning our indebtedness, the lenders could elect to declare all amounts outstanding to be due and greenhouse gas restrictionspayable 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.

DueOur substantial indebtedness could limit cash flow available for our operations and could adversely affect our ability to concern overservice debt or obtain additional financing if necessary.

As of December 31, 2018, we had $18 million in borrowings outstanding under our revolving credit facility (the "Revolving Facility") and $84.5 million in borrowings outstanding under our term loan facility (the "Term Loan Facility" and, together with the riskRevolving Facility, the "Credit Facilities"). Pursuant to the terms of climate change,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 countries have adopted,important exceptions, and additional indebtedness that we may incur from time to time to finance projects or are consideringfor other reasons in compliance with these restrictions could be substantial. If we incur significant additional indebtedness, the adoption of, regulatory frameworks to reduce greenhouse gas emissions. These include adoption of cap and trade regimes, carbon taxes, restrictive permitting, increased efficiency standards, and incentives or mandates for renewable energy. These requirementsrelated risks that we face could make our products more expensive, lengthen project implementation times, and reduce demand for hydrocarbons, as well as shift hydrocarbon demand toward relatively lower-carbon sources such as natural gas. Current and pending greenhouse gas regulations may also increase our compliance costs, such as for monitoring or sequestering emissions.increase.

VaryingOur 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.

Our 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 competitive conditions couldand to financial, business and other factors, many of which are beyond our control. We cannot provide assurance that our business will generate sufficient cash flow from operations to fund our cash requirements and debt service obligations.

Conditions in the global economy may adversely impact demand for productsaffect our results of operations, financial condition and metalscash 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, 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
9

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.

Environmental regulationTo service our current, and any future, indebtedness, we will require a significant amount of cash, which may adversely affect our future results.

Our industriesability to generate cash depends on many factors beyond our control, and any failure to meet our debt service obligations

could harm our business, results of operations and financial condition. Our ability to make payments on and to refinance our indebtedness, and to fund working capital needs and planned capital expenditures, will depend on our ability to generate cash in the future. This, to a certain extent, is subject to general economic, financial, competitive, business, legislative, regulatory and other factors that are beyond our control.

If our business does not generate sufficient cash flow from operations or if future borrowings are not available to us in an amount sufficient to enable us to pay our indebtedness, or to 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 able 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 operations. 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 debt 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 conditions.

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 material adverse effect on our results of operations and financial condition.

While we adapt our manufacturing and distribution processes and controls to minimize 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 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.

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. 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 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 synthetic wax segment and use additional non-primary raw materials in the production of our products in the specialty petrochemical segment and synthetic wax 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.

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.

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 environmental regulation pursuantlaws and regulations related to a varietythe protection of federalthe environment. These laws and state regulations.  Such environmental legislation imposes,regulations continue to increase in both number and complexity and affect our operations with respect to, among other things,things: the discharge of pollutants into the environment; emissions into the atmosphere (including greenhouse gas emissions); and restrictions, liabilities and obligations in connection with storage, transportation, treatment and disposal of hazardous substances and waste. LegislationWe are also requiressubject to laws and regulations that require us to operate and maintain our facilities to the satisfaction of applicable regulatory authorities. Costs to comply with these regulations are significant to our business.  FailureIn addition, failure to comply with these laws or regulations, or failure to obtain required permits from applicable regulatory authorities, may expose us to fines, penalties or interruptions in operations. To the extent these capital expenditures or operating costs are not ultimately reflected in the prices of our products and services, or that we are subject to fines, penalties or other interruptions in our operations, our business, results of operations, financial position and cash flows may be adversely affected.

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.

If we are not able to continue the technological innovation and successful commercial introduction of new products, our customers may turn to other producers to meet their requirements, which may adversely affect our results of operations, financial position 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 different risk profiles, or require new technological and increased performance specifications that would require us to develop customized products. Our future growth and profitability will depend on our ability to maintain or enhance technological capabilities, develop and market products and applications that meet changing customer requirements and successfully anticipate or respond to technological changes in a cost effective and timely manner. Our inability to maintain a technological edge, innovate and improve our products could cause a decline in the demand and sales of our products and adversely affect our results of operations, financial position 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 materialsubject 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, some of the finished goodschanges 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 customers produce, such as expandable polystyrene (EPS),profitability.

Legal requirements are frequently changed and subject to increasing scrutinyinterpretation, and regulation, which could leadwe are unable to a reduction in demand for our products.

Safety, business controls, environmental and cyber risk management

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

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 ourultimate cost of compliance and government actions to cancel contractswith these requirements 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,their effects on 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.operations. We may be required to make significant capital expenditures or modify our business practices to comply with non-U.S. governmental laws and regulations.  It is also possible that theseexisting or future laws and regulations, which may in the future add significantly toincrease our operating costs or may significantlyand materially 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 aware of any specific situations of this nature, but there are always opportunities for this type of difficulty to arise in the international business environment.

Loss of key personnel and management effectiveness

In order to be successful, we must attract, retain and motivate executives and other key employees including those in managerial, technical, sales, and marketing positions. We must also keep employees focused on our strategies and goals. The failure to hire, or loss of, key employees could have a significant adverse impact on operations.  An important component of our competitive performance is our ability to operate efficientlyour business.

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 ability to manage expensesfuture business, results of operations 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 transactionsfinancial condition.

As part of our business strategy, we sometimes engage in discussions with third parties regardingfrom time to time explore possible investments, acquisitions, strategic alliances, joint ventures, divestitures and outsourcing transactions (“extraordinary transactions”(collectively, "extraordinary transactions") and enter into agreements relating to such extraordinary transactions in order to further our business objectives. In order toTo pursue this strategy successfully, we must identify suitable candidates for, and successfully complete, extraordinary transactions, some of which may be large and complex, and manage post-closing issues such as the integration of acquired companiesbusinesses or employees. IntegrationThe expense and other risks ofeffort incurred in exploring and consummating extraordinary transactions, canthe 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 more pronounced for largersuccessful 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 more complicated transactions, or if multiple transactions are pursued simultaneously. If weoperations. Our due diligence may fail to identify and complete successfully extraordinary transactions that further our strategic objectives,all of the problems, liabilities or other shortcomings or challenges of an acquired business, product or technology. Moreover, we may be required to expend resources to develop products and technology internally, we may be atincur significant expenses whether or not 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:contemplated extraordinary transaction is ultimately consummated.

Combining product offerings and entering into new marketsAdditionally, in whichconnection with any extraordinary transaction 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 mayconsummate, we many 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 pricingsynergies and other terms ofbenefits we expect to achieve (on our contracts for extraordinary transactions require us to make estimatesexpected timeframe, or at all), and assumptions at the time we enter into these contracts, and, during the course of our due diligence, 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 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. Managingproceed with announced transactions. Further, managing extraordinary transactions requires varying levels of management and employee resources, which may divert our attention from other business operations. These extraordinary transactions also have resulted

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 result in significantinclude 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, and expenses and charges to earnings. Moreover, we have incurred and will incur additional depreciation and amortization expense over the useful livessuch as for monitoring or sequestering emissions.

Adverse results 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 acquisitionlegal proceedings could materially adversely affect our ability to borrow and result in more restrictive borrowing terms. In addition, our effective tax rate on an ongoing basis is uncertain, and extraordinary transactions could impact our effective tax rate. We also may experience risks relating to the challenges and costs of closing an extraordinary transaction and the risk that an announced extraordinary transaction may not close.

As a result, any completed, pending or future transactions may contribute to financial results that differ from the investment community’s expectations in a given quarter.us.

Guaranteeing performance by others including third partiesWe are subject to 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 ISIL terrorist related activities and civil unrest in the Middle East, have caused uncertainty in the world’s financial markets and have significantly increased global political, economic and social instability, including in Saudi Arabia, a country in which we have a substantial investment.  It is possible that further acts of terrorism mayfuture be directed against the United States domestically or abroad, and such acts of terrorism could be directed against our investment in those locations.  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 components from our suppliers, create delays and inefficiencies in our supply chain and result in the need to impose employee travel restrictions. We are predominantly uninsured for losses and interruptions caused by terrorist acts, conflicts and wars. Our future revenue, gross margin, expenses and financial condition also could suffer duesubject to a variety of international factors, including:

•     Ongoing instability or changeslegal proceedings and claims that arise out of the ordinary conduct of our business, including legal proceedings brought in a country’s or region’s economic or political conditions, including inflation, recession, interest rate fluctuations and actual or anticipated military or political conflicts;

•     Longer accounts receivable cycles and financial instability among customers;

•     Trade regulations and procedures and actions affecting production, pricing and marketingnon-U.S. jurisdictions. Results of products;

•     Local labor conditions and regulations;

•     Geographically dispersed workforce;

•     Changes in the regulatory or legal environment;

•     Differing technology standards or customer requirements;

•     Import, export or other business licensing requirements or requirements relating to making foreign direct investments, which could affect our ability to obtain favorable terms for labor and raw materials or lead to penalties or restrictions;

•     Difficulties associatedproceedings cannot be predicted with repatriating cash generated or held abroad in a tax-efficient manner and changes in tax laws; and

•     Fluctuations in freight costs and disruptions in the transportation and shipping infrastructure at important geographic pointscertainty. Irrespective of exit and entry for our products and shipments.

Business disruption

Business disruptions could harm our future revenue and financial condition and increase our costs and expenses. Our operations could be subject to earthquakes, power shortages, telecommunications failures, water shortages, tsunamis, floods, hurricanes, typhoons, fires, extreme weather conditions, medical epidemics and other natural or manmade
12

disasters or business interruptions, for some of which weits merits, litigation may be self-insured. The occurrenceboth lengthy and disruptive to our operations and may cause significant expenditure and diversion of any of these business disruptionsmanagement attention. We may be faced with significant monetary damages or injunctive relief against us that could harm our revenue and financial condition and increase our costs and expenses.

Dependence on AMAK management

We rely upon AMAK’s management and Board to employ various respected engineering and financial advisors to assist in the development and evaluation 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

Although we believe that we have significant influence over the operating and financial policies of AMAK, we do not control AMAK’s activities.  The extent to which we are able to influence specific operating and financial decisions dependsan adverse impact on our ability to persuade other AMAK board membersbusiness and management regarding these policies.  Our ability to persuade them may be adversely affected by cultural differences, differing accounting and management practices, differing governmental laws and regulations, and the fact that the AMAK mining project is halfway around the world from our main baseresults of operations should we fail to prevail in the United States.

Inability to recoup investment in AMAK

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

Cancellation of the current mining leases held by AMAK

In the event 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.

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.certain matters.

Cost pressures could negatively impact AMAK’sAMAK's operating margins and expansion plansplans.

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.

13

Excess products

As noted previously, an important component of our competitive performance is our ability to minimize the production of low margin products on an on-going basis.  Although the hydrocarbon constituents comprising the petrochemical feedstock we use may vary somewhat over time, they tend to fall into relatively narrow percentage bands as compared to overall feedstock composition.  By nature of the fractionation process that we utilize, if we make one product, we make them all; therefore, when we receive a significant order for a particular finished product, additional products may be manufactured necessitating sales into secondary, lower margin markets.  We continue to investigate options to maintain or improve margins.

An impairment of goodwill could negatively impact our financial results of operations.

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

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 debt service obligations on the variable rate indebtedness will increase even though the amount borrowed will remain the same, and 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 are exposed to local business risks in different countries, which could have a material adverse effect on our financial condition and results of operations.

Although 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 a variety of international 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 actual or anticipated military or political conflicts (including the potential impact of continued hostilities and conflict in Yemen on the operations of AMAK);
longer accounts receivable cycles and financial 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 trade barriers;
regulations favoring local contractors or requiring foreign contractors to employ citizens of, or purchase supplies from, a local jurisdiction;
local labor conditions and regulations and the geographical dispersion of the workforce;
changes in the regulatory or legal environment;
differing technology standards or customer requirements;
import, export or other business licensing requirements or requirements relating to making foreign direct investments, which could affect our ability to obtain favorable terms for labor and raw materials or lead to penalties or restrictions;
data privacy regulations;
risk of non-compliance with the U.S. Foreign Corrupt Practices Act or similar anti-bribery legislation in other countries by agents or other third-party representatives;

risk of nationalization of private enterprises by foreign governments (including the risk that AMAK's mining and exploration leases may be terminated by the Saudi Ministry of Petroleum and Minerals);
foreign currency exchange restrictions and fluctuations;
difficulties associated with repatriating cash generated or held abroad in a tax-efficient manner and changes in tax laws; and
fluctuations in freight costs and disruptions in the transportation and shipping infrastructure at important geographic points of exit and entry for our products and 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 raw materials from our suppliers and create delays and inefficiencies in our supply chain. We are also predominantly uninsured for losses and interruptions caused by terrorist acts, conflicts and wars.

We may have additional tax liabilities, which may adversely affect our financial position.

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 position and cash flows could be adversely affected.

The U.S. Tax Cuts and Jobs Act ("TCJA") was enacted on December 22, 2017, and introduces significant changes to U.S. income tax law. Accounting Standards Codification 740, Accounting for Income Taxes, requires companies to recognize the effects of tax law changes in the period of enactment. Effective in 2018, the TCJA made a number changes, such as reducing the U.S. statutory tax rate from 35% to 21%, creating new taxes on certain foreign sourced earnings and certain related-party payments, which are referred to as the global intangible low taxed income tax and the base erosion tax, respectively, establishing a dividends received deduction for dividends paid by foreign subsidiaries to the U.S., the elimination or limitation of certain deductions, and imposing a mandatory tax on previously unrepatriated earnings accumulated offshore. Due to the timing of the new tax law provided in the TCJA and the substantial changes it brings, the Staff of the SEC issued Staff Accounting Bulletin No. 118, which provides registrants with a measurement period to report the impact of the new US tax law. As a result, the recorded and estimated impacts of the TCJA may change in future periods, which may adversely affect our estimates, our results of operations, financial position and cash flows.

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.

We from 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 may be unable to recover our investment in AMAK, which could adversely affect our results of operations and financial condition.

We will only recover our investment in AMAK through the receipt of distributions or future share repurchases from AMAK or the sale of part or all of our interest in AMAK. If AMAK does not continue to be profitable, our ability to recover our investment will be adversely affected. Moreover, if AMAK continues to be profitable, there can be no assurance that the board of directors of AMAK will determine that it is in the best interests of AMAK and its shareholders to make distributions to its shareholders or to initiate additional share repurchases. In addition, we understand that AMAK is required to sell a portion of its equity to the public once AMAK has been profitable for two years. While the proceeds of such a sale might allow us to recover our investment in AMAK, there is no assurance that the market conditions for any such public sale will be favorable enough to allow us to recover our investment or that some or all of our shares in AMAK will be include in any such sale. To the extent we are unable to recover our investments in AMAK, our results of operations and financial condition may be adversely affected.


AMAK may have fewer mineral reserves than its estimates indicate.

Fluctuations in the price of commodities, variation in production costs or different recovery rates could result in AMAK's estimated reserves being revised in the future. If such a revision were to indicate a substantial reduction in proven or probable reserves at one or more of AMAK's projects, it could adversely affect our investment in AMAK.

Domestic or international terrorist attacks may disrupt our operations or otherwise have an adverse impact on our business.

It is possible that further acts of terrorism may be directed against the U.S. domestically or abroad, and such acts of terrorism could be directed against our investment in those locations. Moreover, chemical related assets, and U.S. corporations such as ours, may be at a greater risk of future terrorist attacks than other possible targets. The resulting damage from such an event could include loss of life, property damage or site closure. Any, or a combination, of these factors could adversely impact our results of operations, financial position and cash flows.

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 position and cash flows.

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 petrochemical 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.

TC offers pastillating for waxes, polymers and resins, flaking capabilities, as well as solids packaging services.
Investment in AMAK

As of December 31, 2015,2018, we owned a 35%33% interest in AMAK.

Prior to December 2008, we held a thirty (30) 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 exceed twenty (20) years. The lease and other related assets located in Saudi Arabia were contributed to AMAK in December 2008. The above-ground ore processing facility became fully operational during the second half of 2012.   Late in the fourth quarter of 2015 AMAK temporarily closed the operation to preserve the assets in the ground while initiating steps to improve efficiencies and optimize operations. The facility resumed operation in the fourth quarter of 2016 and operating rates, metal recoveries and concentrate quality continued to improve steadily throughout 2017 and 2018.

14

AMAK shipped approximately 58,000, 28,000, and 51,000 metric tons of copper and zinc concentrate to outside smelters during 2018, 2017 and 2016, respectively. In 2014 AMAK initiated operation of its precious metal recovery circuit at the mill and produced gold and silver doré intermittently through 2014 and 2015. The precious metals circuit was recommissioned in fourth quarter of 2017 and produced commercial quantities of gold and silver bearing doré in 2018.
The facility includes an underground mine, ore-treatment plant and related infrastructures. The ore-treatment plant is comprised of primary crushing, ore storage, SAG milling and pebble crushing, secondary ball milling, pre-flotation, copper and zinc flotation, concentrate thickening, tailings filtration, cyanide leaching, reagent handling, tailings dam and utilities. Related infrastructure includes a 300 men 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.

Metal price assumptions follow U. S. Securities and Exchange CommissionSEC guidance not to exceed a three year trailing average. The following chart illustrates the change in metal prices from the previous three year average to current levels:

For purposes of calculating proven and probable mineralized materials, a dilution of 5% at zero grade on 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 wallrackwall-rock adjacent to
15

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
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 km2 or 37,313 acres of territory relatively close to the current mine. The new territory comprises the Guyan and Qatan exploration licenses covering 151 km2 and within the Guyan exploration license, a 10 km2 or 2,471 acre mining lease which has potential for significant gold recovery. Some exploration holes were drilled in both Guyan and Qatan up to 40 years ago, but no reserves were attributed to these areas. Exploration activities were restarted in both of these areas during 2016, and SRK Consulting prepared a JORC compliant report in May 2017 showing approximately 99,000 ounces at the Jebel Guyan zone excluding other nearby prospects. The diamond drilling program continues at both the Jebel Guyan and Al Aqiq zones, testing depth and extension of mineralization with confirmed mineralization intersected at an additional 50 meters depth the Guyan zone. A JORC compliant 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 indicated that 87.7%84.7% of the copper and 82.6%78.0% of the zinc could be recovered in copper and zinc concentrates. Overall, gold and silver recovery from the ore was estimated to be 77.3% and 81.3%, respectively, partly into copper concentrate and partly as bullion through cyanide processing of zinc concentrates and mine tailings. Further studies recommended by consultants may improve those recoveries and thus the potential profitability of the project; however, there can be no assurances of this effect.

AMAK contracted with SRK Consulting for a reserves update in 2017 and SRK reported JORC compliant reserves in August 2017. The SRK reserves estimate has since been updated by AMAK resource geologist (Qualified Person - QP as defined in JORC Code) in January 2018 and February 2019 with additional drill-hole data (85 holes and 8,970 meters in 2017 and 91 holes and 9,134 meters in 2018) and more comprehensive geological information from actual mining fronts.

The updated reserves reflect a 1.5M tonnes increase to find more reserves within the Lease area, asMRE of January 2018, due to additional drilling at Moyeath and Saadah orebodies. The depth of three orebodies are not tested yet and underground drilling will continue in 2019 and coming years to extend the ore zones are all openorebody at depth. Further diamond
Access and all mine services already exist at the Moyeath orebody and AMAK recently started ore mining in the last quarter of 2018. In 2019, AMAK estimates that approximately 50,000 tonnes will be mined out from Moyeath orebody. A drilling program of 8,000 meters (8 months) has been completed at Moyeath, which upgraded 0.8M tonnes of inferred class to indicated class, which eventually mine designed and included in the life of mine schedule. AMAK believes that the Moyeath orebody is required to quantifyhigh grade for zinc and average grade as a copper. AMAK believes that Moyeath is the additional mineralization associatedmost attractive opportunity for an extended life and higher zinc metal recovery through the life of mine.
The metallurgical recoveries are assumed as 83% for copper and 75% for zinc after 2019. Actual metal recoveries in 2018 increased throughout the year so that these recovery assumptions are realistic and in line with these zones. A significant featureactual performance 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 may be developed into sizeable ore tonnages by thorough and systematic exploration. Similarly, systematic prospecting of the small surface indicators of mineralization in the area could yield significant tonnages of new ore.  Updates to the feasibility study were completed in 1996, 2005 and July 2009.

An updated reserve study or audit has not been performed over the last three years.  AMAK is however, preparing a policy regarding updating reserve studies and audits in 2016.process plant.

Outside of the facilities that we own, SHR has a leased corporate and sales office in Sugar Land, Texas.

Item 3. Legal Proceedings.
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 March 21, 2011, Mr. El Khalidi filed suit against the Companyon our business, prospects, financial condition or results of operations. We may become involved in Texas alleging breach of contract and other claims.  The 88th Judicial District Court of Hardin County, Texas dismissed all claims and counterclaims for want of prosecution in this matter on July 24, 2013.  The Ninth Court of Appeals subsequently affirmed the dismissal for want of prosecution and the Supreme Court of Texas denied Mr. El Khalidi’s petition for review.  On May 1, 2014, Mr. El Khalidi refiled his lawsuit against the Company for breach of contract and defamationmaterial legal proceedings in the 356th Judicial District Court of Hardin County, Texas.  The case was transferred to the 88th Judicial District Court of Hardin County, Texas where it is currently pending.  On April 6, 2015, Mr. El-Khalidi nonsuited his defamation claim.  We believe that the remaining claims are unsubstantiated and plan to vigorously defend the case.  Liabilities of approximately $1.0 million remain recorded, and the options will continue to accrue in accordance with their own terms until all matters are resolved.future.

On September 14, 2010, SHR received notice of a lawsuit filed in the 58th Judicial District Court of Jefferson County, Texas which was subsequently transferred to the 11th Judicial District Court of Harris County, Texas.  The suit alleges that the plaintiff became ill from exposure to asbestos.  There are approximately 44 defendants named in the suit.  On December 15, 2015, plaintiff agreed to settle all claims against SHR for a de minimis amount.

On April 30, 2015, TC and TREC received notice of a lawsuit filed in the 152nd Judicial District Court of Harris County, Texas.  The suit alleges that the plaintiff, an independent contractor employee, was injured while working on a product line at TC.  We have placed our insurers on notice and plan to vigorously defend the case. 

On or about August 3, 2015, SHR received notice of a lawsuit filed in the 14th Judicial District Court of Calcasieu Parish, Louisiana.  The suit alleges that the plaintiff became ill from exposure to benzene.  SHR placed its insurers on notice.  Its insurers retained a law firm based in Louisiana to defend SHR.

Non-GAAP Financial Measures

We include in this Annual Report the non-GAAP financial measures of EBITDA, Adjusted EBITDA, and Adjusted EBITDANet Income (Loss) 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 and Adjusted EBITDA: We define EBITDA as net income (loss) plus interest expense (benefit) including derivative gains and losses, income taxes, depreciation and amortization. We define Adjusted EBITDA as EBITDA 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 or gains from equity issuances.  Both of these measures are not measures of financial performanceissuances, and plus or liquidity under U.S. GAAP and should be considered in addition to, notminus gains or losses on acquisitions.

Adjusted Net Income (Loss): We define Adjusted Net Income (Loss) as a substitute for, net income (loss), nor as an indicator of cash flows reported plus or minus tax effected equity in accordance with U.S. GAAP. These measures are used as supplemental financial measure by managementAMAK's earnings and external users of our financial statements such as investors, banks, research analystslosses, minus tax effected restructuring and others.  We believe that these non-GAAP measures are useful as they exclude transactions not related to our core cash operating activities.

severance expenses, and adjustments for tax law changes in 2017.
The following table presents a reconciliation of net income to EBITDA and Adjusted EBITDA(loss), our most directly comparable GAAP financial performance measure for each of the periods presented.presented, to EBITDA, Adjusted EBITDA, and Adjusted Net Income.

Overview
The following discussion and analysis of our financial results, as well as the accompanying consolidated financial statements and related notes to consolidated financial statements to which they refer, are the responsibility of the management of the Company. Our accounting and financial reporting fairly reflect our business model involving the manufacturing and marketing of specialty petrochemical products and specialty waxes. Our business model involves the manufacture and sale of tangible products and providing custom processing services. Our consistent approach to providing high purity products and quality services to our customers has helped to sustain our current position as a preferred supplier of various specialty petrochemical products.

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.

Specialty Petrochemical Operations

WorldwideSHR's worldwide specialty petrochemical demand improvedincreased during 2015, and we benefitted from2018 compared to 2017. Product sales revenue increased 19.3% driven primarily by volume growth of 7.6%. Overall product prices also increased compared to 2017 primarily due to higher feedstock costs in 2018 compared to 2017. We continued operational excellence andto emphasize our competitive advantages achieved through our business mix and focus on producing high quality products and outstanding customer service.

service and responsiveness. We are also focused on improving operations and plant reliability.
During 20152018 feedstock prices continued the decline which beganwere about 24%, or $0.28 per gallon, higher than 2017 reflecting higher crude oil prices. After steadily increasing for most of 2018 feedstock prices declined sharply in the fourth quarter of 2014.  Average price fell $0.46 per gallon from end of year 2014 to end of year 2015.  Typically, during falling prices we experience better margins since almost2018. About 60% of our selling pricesprime products are onsold under formula pricing which follows marketwhereby feedstock costs are passed along to the customer typically with a one month lag. Thus, when feedstock prices calculated uponstart rising, we experience lower margins as formula pricing lags feedstock costs. During most of 2018 prime products margins were pressured due to rising feedstock costs and as a result of greater competitive pricing pressure on prime products sales that are based on non-formula pricing. Our byproduct margins were under pressure in the prior month.

fourth quarter due to the Advanced Reformer outage as we sold byproducts at prices below the cost of feedstock.
Specialty Wax Operations

Most wax markets are mature. Key applications for polyolefinour 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 developed economies due to new infrastructure build-outs.  New construction and upgrades to the existing water network should encourage theU.S.   The PVC market to grow at GDP growth rates. Global demand for polyethylene and polypropylene waxes, our target market is expected to grow to around 2 billion pounds globally by 2020. Weat GDP rates; however, we expect to penetrate a larger percentageget more traction of our products within this market with acceptance of our new PVC grade waxes. The global wax market is benefiting 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 approximately 5% in 2018 from 2017 while revenues increased approximately 13%.

Restructuring and Severance Impact
During 2018, the Company incurred restructuring and severance expenses of $2.3 million which are included in General and Administrative Expenses. These expenses are primarily attributable to the termination of certain executives during 2018 as part of the market withrestructuring of executive management and to the reduction in the workforce at our enhanced quality product by giving customersSilsbee, Texas facility in December 2018. These expenses relate to severance, stock compensation for continued vesting of time-vested shares issued under the Company's long-term incentive plan, and certain employee benefits including medical insurance and vacation. As of December 31, 2018, approximately $1.1 million had been incurred, and an alternativeadditional liability of $1.2 million was accrued related to synthetic Fischer-Tropsch waxes.future benefits.

Hurricane Harvey Impact

The financial impact of Hurricane Harvey to our company was significant. Harvey made landfall on the Texas Gulf Coast on August 25, 2017, and affected operations at both SHR and TC. We estimated the total negative impact to 2017 EBITDA ranged from approximately $1.5 million to $1.8 million. This included expenses related to generator rentals, overtime labor, and maintenance and repairs of approximately $0.7 million. This estimate also included lost sales due to outages at customer and supplier facilities. Neither of our facilities suffered any significant damage.

Cash provided by financing activities during fiscal 2014 was approximately $66.6 million versus cash used of $2.4 million during the corresponding period of 2013.  During 2014 we entered into an amended and restated loan agreement with the bank as discussed in Note 12 for the Acquisition, financing for the D-train expansion and a working capital line.  We also made principal payments of $9.2 million on our term debt and $11.5 million on our line of credit.projects.

Credit Agreement

OnIn October 1, 2014, TOCCO, SHR, GSPL and TC (SHR, GSPL and TC collectively the “Guarantors”) entered into an Amendedamended and Restated Credit Agreement (“ARCrestated credit agreement (as amended to the date hereof, the “ARC Agreement”), which originally provided (i) a revolving credit facility (which we refer to herein as the “Revolving Facility”) with revolving commitments of $40.0 million and (ii) term loan borrowings consisting of (A) a $70.0 million single advance term loan incurred to partially finance the lendersacquisition of TC (which we refer to as the “acquisition loan”) and (B) a $25.0 multiple advance term loan facility for which from timeborrowing availability ended on December 31, 2015 (which we collectively refer to time are partiesherein as the “Term Loan Facility” and, together with the Revolving Facility, the “Credit Facilities”).

Only July 31, 2018, TOCCO and the Guarantors entered into a Fourth Amendment to the ARC Agreement (collectively,(the “Fourth Amendment”) pursuant to which the “Lenders”) and Bank of America, N.A., a national banking association, as Administrative Agent forrevolving commitments under the Lenders, and Merrill Lynch, Pierce, Fenner & Smith Incorporated as Lead Arranger.

Pursuant to the terms and conditions ofFourth Amendment, total borrowings under the ARC Agreement, TOCCO may (a) borrow, repay and re-borrow revolving loans (collectively, the “Revolving Loans”) from timeTerm Loan Facility were increased to time during the period ending September 30, 2019, up to but not exceeding at any one time outstanding $40.0$87.5 million (the “Revolving Loan Commitment”) and (b) request up to $5.0under a single combined term loan, which comprised new term loan borrowings together with approximately $60.4 million of letters of credit and $5.0 million of swingline loans.  Each of the issuance of letters of credit and the advance of swingline loans shall be considered usage of the Revolving Loan Commitment.  Allpreviously outstanding term loans under the Revolving Loans must be repaidTerm Loan Facility. The $60.4 million of previously outstanding term loans included the remaining outstanding balances on October 1, 2019.  Asthe Acquisition loan and the multiple advance term loan facility described above. Proceeds of December 31, 2015, TOCCO hadthe new borrowings under the Term Loan Facility were used to repay a portion of the outstanding borrowings under the Revolving Loans aggregating $1.0 million.

As of December 31, 2015, TOCCO2018, we had $18 million in borrowings outstanding under the Revolving Facility and $84.5 million in borrowings outstanding under the Term Loan Facility. In addition, we had the ability to borrow an additional approximately $18 million under our Revolving Facility at December 31, 2018. TOCCO’s ability to make additional borrowings under the Acquisition Term Loan aggregating $61.3 million.

UnderRevolving Credit Facility at December 31, 2018 was limited by, and in the future may continue to be limited by, our obligation to maintain compliance with the covenants contained in the ARC Agreement TOCCO also has(including maintenance of a maximum Consolidated Leverage Ratio and minimum Consolidated Fixed Charge Coverage Ratio (each as defined in the right to borrow $25.0 million in a multiple advance loan (the “Term Loans,” together with the Revolving Loans and Acquisition Term Loan, collectively the “Loans”ARC Agreement)).  Borrowing availability under the Term Loans ended on December 31, 2015.  The Term Loans convert from a multiple advance loan to a “mini-perm” loan once TOCCO has fulfilled certain obligations such as certification that construction of D-Train was completed in a good and workmanlike manner, receipt of applicable permits and releases from governmental authorities, and receipt of releases of liens from the contractor and each subcontractor and supplier.  The Loans also include a $40,000,000 uncommitted increase option (the “Accordion Option”).  As of December 31, 2015, TOCCO had borrowed funds under this agreement aggregating $20.0 million.

Gross Revenue

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 decrease in processing fees of 13.7%.

2013-2014

2017-2018
Revenues increased from 20132017 to 20142018 by approximately 20.4% primarily18.7% due to an increase in specialty petrochemical sales volume and an increase in average selling prices.
2016-2017
Revenues increased from 2016 to 2017 by approximately 15.6% due to an increase in sales volume of 23.4%9.1% and an increase in processing fees of 20.4%.

Petrochemical Product Sales

2014-2015

Petrochemical product sales revenue decreased 23.5% from 2014 to 2015 due to a decrease in the average selling price of 27.1%.  We saw7.7% partially offset by a significant decline in raw material prices beginning in the fourth quarter of 2014 which continued
25

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.  Foreign sales volume accounted for approximately 25.2%processing fees of volume and 27.9% of revenue for21.7%.
Specialty Petrochemical Product Sales
2017-2018
Specialty petrochemical product sales during 2015 as comparedincreased 19.3% from 2017 to 27.7% of volume and 30.8% of revenue during 2014.

2013-2014

Petrochemical product sales increased 20.4% from 2013 to 20142018 due to an increase in total sales volume of 23.4% while7.6% and an increase in average selling price of 10.9%. Our average selling price increased partly because of higher feedstock costs. A large portion of our prime products sales are contracted with pricing formulas which are tied to prior month Natural Gasoline prices which is our primary feedstock. Average delivered feedstock price for 2018 was 21.1% higher than 2017 as Natural Gasoline prices rose with crude oil prices for most of the year but then declined slightly by 2.5%.  We saw a significant declinesharply in raw materialthe fourth quarter. The increase in average selling prices was also due to higher non-formula pricing for our prime products. Additionally, prices for byproducts in 2018 were about 24% higher than in 2017 due to higher prices for the components in our byproducts stream. This also contributed to higher overall selling prices. Byproduct prices fell significantly during the fourth quarter due to the Advanced Reformer outage and inability to upgrade byproducts. Additionally, in the fourth quarter byproduct prices fell faster than feedstock prices resulting in negative margins.
Prime product sales volume (total specialty petrochemical product sales volume less byproduct sales volume) increased 8.5% from 2017 to 2018 as demand was greater in all of 2014 which caused our end-use markets and especially in the Canadian oil sands market. Sales to the Canadian oil sands market continues to be volatile. We believe the volatility in demand is primarily based on continued manufacturing efficiencies at customer sites and by the crude oil pricing environment. Margins on our specialty petrochemical products continued to be negatively impacted by shortfall fees that we incurred due to feedstock purchases below minimum amounts as prescribed by our agreement with suppliers. However the amount of the penalties in 2018 were significantly less than 2017.
Foreign sales volume accounted for approximately 25.5% of volume and 27.6% of revenue for specialty petrochemical product sales during 2018 as compared to 20.4% of volume and 23.3% of revenue during 2017. The increase in foreign sales volume was

due to higher demand in the Canadian oils sands market. Excluding oil sands, foreign sales volumes in 2018 grew by 22% from 2017.
2016-2017
Specialty petrochemical product sales increased 17.5% from 2016 to 2017 due to an increase in total sales volume of 9.1% and an increase in average selling price of 7.7%. Our average selling price increased partly because a large portion of our sales are contracted with pricing formulas which are tied to prior month Natural Gasoline prices which is our primary feedstock. Average delivered feedstock price for the year2017 was 17.8% higher than 2016. Additionally, prices for byproducts were about 17% higher than in 2016 which also contributed to decline.  Deferredhigher overall selling prices. Prime product sales volume (total specialty petrochemical product sales volume less byproduct sales volume) increased 12.6%9.5% from the end of 20132016 to 2014 which delayed recognition until 2015.

Processing

2014-2015

Processing revenues decreased 13.7% from 2014 to 20152017 primarily due to lower run rates being required byhigher demand across many of our customers.

2013-2014

Processing revenues increased 20.4%end-use markets. Sales to the Canadian oil sands market were down from 2013 to 20142016 due to the continued benefit from renegotiated contacts.downturn in that market. Margins on our specialty petrochemical products continued to be negatively impacted by shortfall fees that we incurred due to feedstock purchases below minimum amounts as prescribed by our agreement with suppliers. The amount of the penalties in 2017 was approximately the same as in 2016.
We remain dedicatedForeign sales volume accounted for approximately 20.4% of volume and 23.3% of revenue for specialty petrochemical product sales during 2017 as compared to maintaining a certain level22.7% of toll processing businessvolume and 26.3% of revenue during 2016. The decline in foreign sales volume was due to lower demand in the facility and continueCanadian oils sands market. Excluding oil sands, foreign sales volumes in 2017 grew by 8.1% from 2016.
Processing Fees
2017-2018
Processing fee were approximately flat from 2017 to pursue opportunities.2018.
2016-2017
Processing fees decreased 21.7% from 2016 to 2017 primarily due to a reduction in fees associated with a customer who reimbursed us for installation expenses plus a markup. We were successful in negotiating a contract extension with one of our processing customers whose contract was set to expire at the end of 2017.

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

2014-2015

2017-2018
Cost of Sales decreased 31.6%increased 32.3% from 20142017 to 20152018 due primarily to a 46.9% decrease in the average cost per gallon of raw material.  This was offset slightly by higher raw material volumes being processed in order to supportcosts, higher operating expense and the 5.0% increase in sales volume. Our raw material composition fluctuated during the year.average delivered feedstock cost per gallon increased approximately 21% over 2017 and volume processed increased about 8%. We use natural gasoline as our feedstock which is the heavier liquid remaining after butaneethane, propane and propanebutanes 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. WeThe price of natural gasoline is well correlated with the price of crude oil. With the start up and stable operation of our Advanced Reformer unit we continue to investigate alternative feedstock sources which containconvert the lower percentages of less desirablevalue components in an effortour feed into higher value products, thereby allowing us to reducesell our byproducts at higher prices than would be realized without the amount of byproduct sold into secondary markets at lower margins, thereby increasing overall profitability.Advanced Reformer unit.

2013-2014

2016-2017
Cost of Sales increased 18.6%15.8% from 20132016 to 20142017 primarily due in part to a 19.4% increase in volumes processed to support the increase in sales volume slightly offset by a 4.4% decrease in theand higher raw material costs. Our average delivered feedstock cost per gallon of raw material.increased 17.8% over 2016 and volume processed increased 10.0%. We use natural gasoline as feedstock which is the heavier liquid 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.

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

2014-2015

2017-2018
Total Operating Expense increased 3.9%24.4% from 20142017 to 2015.2018 resulting in a $14.4 million increase 2017. The key drivers for the increase were transportation costs, operating labor and depreciation. Transportation costs increased due to higher sales volume, higher rail freight rates and other logistics costs. Operating labor costs were higher due to higher maintenance and contract labor costs primarily associated with the start-up of the Advanced Reformer unit, maintenance and repair costs associated with a toll processing unit and other maintenance activities. Approximately 12.8% of our labor costs were capitalized in 2018 primarily due to the construction of the Advanced Reformer unit; whereas, in 2017 approximately 28% was capitalized.

We implemented a reorganization and workforce reduction at our Silsbee, Texas facility which reduced the workforce by about 20% at the end of 2018. We expect to realize approximately $2.5 million in annual cost savings as a result of this action. We took a charge of approximately $0.4 million for severance related to this action.
Natural gas expense increased 14.9% from 2017 to 2018 due to an increase in the average per unit cost and volume consumed. Consumption was greater than in 2017 both due to higher sales volume and inefficiencies related to the start-up and operation issues with the Advanced Reformer unit. The average price per MMBTU for 2018 was up about 3.8% from 2017 while volume consumed increased to approximately 1,684,000 MMBTU from about 1,509,000 MMBTU.
2016-2017
Total Operating Expense increased 0.3% from 2016 to 2017. 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 12.5% mainly due to a cost of living adjustment that was given mid-year 2015, additional profit sharing distributions based upon profitability, and an increase in our employee count for the petrochemical segment.  Employee count increased approximately 9.5% from year end 2014 to year end 2015 as support for the D-train expansion and in preparation for construction of the new reformer unit.

Transportation costs were higher by 7.2% primarily due to an increase in rail freight which includes car rental.  The number of cars in our rail fleet remained 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 acceptable 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.

2013-2014

Total Operating Expense increased 18.4% from 2013 to 2014.  Natural gas labor and transportation are the largest individual expenses in this category.

The cost of natural gas purchasedexpense increased 22.3%48.8% from 20132016 to 20142017 due to an increase in the average per unit cost and additional volume used.consumed. The average price per MMBTU for 20142017 was $4.49$3.24 whereas, for 20132016 the average per unit cost was $3.89.$2.61.

Product Sales
2017-2018
Product sales revenue increased 13.4% and product sales volume increased 5.3% from 2017 to 2018 primarily due to higher on-purpose PE wax sales which benefited from continued growth in growth in our high value waxes. Polyethylene wax sales saw volume increases of 3.5% and revenue from polyethylene wax increased approximately 15.4% both as a result of greater sales volume and a higher value sales mix. Average wax sales price was approximately 9% higher in 2018 compared to 2017.
2016-2017
Product sales revenue increased 17.2% and product sales volume increased 4.4% from 2016 to 2017 primarily due to on-purpose PE wax sales which we were distributing in Latin America for a third party as well as, significant growth in our high value waxes. Polyethylene wax sales saw volume increases of 1.3% and revenue increases of 12.8%. 
Processing Fees

Cost of Sales
2017-2018
Cost of Sales increased 5.7% from 2017 to 2018 due to increases in labor, maintenance, utilities and depreciation which were partially offset by lower wax material costs.   Labor increased approximately due to increased overtime and the addition of personnel to support the new hydrogenation/distillation unit which came on line in 2017 as well as to support other custom processing projects. Maintenance costs increased primarily as a result of the start-up of hydrogenation/distillation and the related operating issues in 2018. Utility costs increased mainly due to greater consumption.
2016-2017
Cost of Sales increased 30.5% from 2016 to 2017 due to increases in material cost, labor, freight, equipment maintenance, and natural gas utilities. Material cost increased primarily due to material costs associated with the on-purpose PE wax sales we distributed into Latin America for a third party. Labor increased due to increased overtime and the addition of personnel to operate the new hydrogenation/distillation unit when it came online in 2017. Freight increased due to the increase in shipments and a change in our shipping terms. We now ship most products with destination terms. Equipment maintenance increased primarily due to the addition of B Plant and the introduction of new custom processing projects. Natural gas utilities increased due to an increase in the per unit cost and in volume consumed because of B Plant and the new hydrogenation/distillation unit.

2014-2015

2017-2018
Equity in Losses of AMAK increased 396.7%decreased 78.9% from 20142017 to 20152018 due to a number of reasons as discussed below.

AMAK’s performance, like the rest of the mining sector,The mine was severely impacted by the continued fallfully operational in metal demand and prices (average spot prices for zinc and copper in fourth quarter 2015 were down approximately 13% and 7%, respectively,2018 as compared to third quarter 2015).  Theoperating on an improving basis throughout 2017. In 2017 costs were increased as the mine also suffered from significant raw material outages andwas not operating inefficiencies.

at full capacity. Metal prices remained strong in 2018.
Shipments decreased 7.4%increased 105% from 20142017 to 20152018 as indicated in the table below.  There was one shipment of zinc in the first quarter, one shipment of copper in the second quarter, one shipment of copper and two shipments of zinc in the third quarter and one shipment of copper (to two customers) in the fourth quarter. AMAK volumes in dry metric tons (dmt) for 20152018 and 20142017 were as follows:

   Zinc  24,547   29,326   (4,779)
   50,925   55,017   (4,092)

In November 2015 the decision was made to temporarily close the mine and to terminate the contract with the operator.  This allows AMAK to preserve asset value while the mill and underground assets are returned to their original condition and equipment upgrades are installed.

Renovation work began at the AMAK facility in December 2015 with zinc and copper production expected to resume in the fourth quarter of 2016.  During the renovation, AMAK’s focus remains on improving recoveries overall and upgrading the precious metals circuit through the installation of SART modifications which should lower chemical use; thereby, reducing operating costs once processing resumes.  In addition, processing of the gold-bearing waste dumps from historical mining at the newly acquired Guyan mining license area are also scheduled to begin in the fourth quarter of 2016.  An exploration program for the rest of Guyan mining lease will commence shortly, along with a systematic program of infill drilling to extend the overall life of the copper and zinc mine.

The renovation work at AMAK is proceeding on schedule and installation of new equipment is expected to finish early in the fourth quarter of 2016.  We believe that AMAK has sufficient capital to complete the planned improvements.  AMAK will self-operate the mine after start-up and has signed a manpower agreement with a Turkish company that will provide greater technical know-how and required management skills in combination with significant cost savings.

The mine operated on an improving basis throughout 2017 while operations were closed for almost all of 2016. However, in AMAK’s results of operations for 2013 also included2017 because the mine was not operating at full capacity but was working toward that goal, costs increased. Also, 2016 was positively affected by the settlement from certain liabilities. Metal prices were strong in 2017 with zinc prices hitting a gain fromten year high during the additional equity issuance by AMAK of $4.0 million.  There was no such gain in 2014.

Shipments decreased by 26.0% from 2013 to 2014 as indicated in the table below.year.   There were no shipmentsunusual items in the first quarter of 2014 due to logistics delays and the rebuilding of warehouse stocks.  Shipments in the second quarter of 2014, while up in number (4), were limited by volume shipped.  Shipments in the third and fourth quarters were also limited by volume shipped.  AMAK volumes in dry metric tons (dmt) for 2014 and 2013 were as follows:

Capital Resources and Requirements
2017-2018
Capital expenditures decreased 58% from 2017 to 2018. The majority of the decrease was due to completion of the Advanced Reformer unit. During 2018 we expended approximately $14.9 million to complete the Advanced Reformer unit which includes $1 million insurance deductible related to the February 2018 fire and $3 million for the catalyst replacement in December 2018, $1.3 million for a rail spur addition and $0.5 million for a truck loading rack.

2014-2015

2016-2017
Capital expenditures increased 74.1%27.4% from 20142016 to 2015.2017. The majority of the increase was due to the construction projects for the hydrogenation/distillation unit and the Advanced Reformer unit. During 20152017 we expended $13.3$10.8 million on the D-train expansion, $1.8hydrogenation/distillation project, $0.9 million on tank farm improvements, $0.6to upgrade B Plant, $32.5 million on spare equipment, $2.8 on pipelineto construct the Advanced Reformer unit, $1.9 million for railspur addition, $1.0 million for additional tankage and upgrades $1.5to existing tankage, $0.9 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,for transport trucks, and $5.6$3.7 million on various plant improvements and equipment.

2013-2014

Capital expenditures increased 104.8% from 2013 to 2014.  During 2014 we expended $6.8 million to begin construction on our D-train expansion, $2.4 million to purchase spare equipment for future use, $0.9 million for tank farm improvements, $1.9 million for various plant upgrades, $0.6 million for a new warehouse and building improvements, $0.5 million for loading rack expansion capabilities, and $.3 million for pipeline upgrades.

Capital expenditures typically average $7.0 million per year for facility improvements.  At December 31, 2015,2018, there was $39.0approximately $18 million available on the Company’sCompany's line of credit. We believe that operating cash flows along with credit availability will be sufficient to finance our 20162019 operations and capital expenditures.

The majority of our operating lease obligations are for railcars as discussed in Note 14 of the Notes to Consolidated Financial Statements. Purchase obligations are primarily related to commitments for our capital construction projects. The anticipated source of funds for payments due within three years that relate to contractual obligations is from a combination of continuing operations supplemented with borrowings under our credit facility.

New Accounting Standards

In May 2014 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, 2014-9, Revenue from Contracts with Customers ("ASU 2014-09"2014-9"). ASU 2014-092014-9 supersedes the revenue recognition requirements of FASB Accounting Standards Codification ("ASC") Topic 605, Revenue Recognitionand most industry-specific guidance throughout the Accounting Standards Codification, resulting in the creation of FASB ASC Topic 606, Revenue from Contracts with Customers. ASU 2014-092014-9 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 currently assessingcompleted its assessment of the potential impact of adopting thisthe adoption of ASU on its consolidated financial statements2014-9 across all revenue streams. This included reviewing current accounting policies and related disclosures.practices to identify potential differences that would result from applying the requirements under the new standard. We completed contract reviews and validated results of applying the new revenue guidance (Note 2). See Revenue Recognition policy note.

In June 2014 the FASB issued ASU No. 2014-12, Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The new standard requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 and can be applied either prospectively or retrospectively to all awards outstanding as of the beginning of the earliest annual period presented as an adjustment to opening retained earnings. Early adoption is permitted. The Company is currently assessing the potential impact of adopting this ASU on its consolidated financial statements and related disclosures.

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.  Early adoption is permitted. The Company is currently assessing the potential impact of adopting ASU 2015-03 and ASU 2015-15 on its consolidated financial statements and related disclosures.

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 is currently assessing the potential impact of adopting this ASU on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02,, Leases (Topic 842). The ASU was issued to This update will increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This update is effective for annual and interim reporting periods beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. In July 2018, the FASB issued ASU affectsNo. 2018-11, Targeted Improvements to ASC 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 provides a number of optional practical expedients in transition. The Company expects to elect: (1) the ‘package of practical expedients’, which permits 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 provides practical expedients for an entity’s ongoing accounting that the Company anticipates making, such as the (1) the election for certain classes of underlying asset to not separate non-lease components from lease components and (2) the election for short-term lease recognition

exemption for all leases that qualify. The Company will adopt ASU 842 as of January 1, 2019, using the alternative modified transition method. In preparation of adopting ASC 842, the Company is implementing additional internal controls to enable future preparation of financial information in accordance with ASC 842. The Company has also substantially completed its evaluation of the impact on the Company’s lease portfolio. The Company believes the largest impact will be on the consolidated balance sheets for the accounting of facilities-related leases, which represents a majority of its operating leases it has entered into as a lessee. These leases will be recognized under the new standard as right of use assets (“ROU”) operating lease liabilities. The Company will also be required to provide expanded disclosures for its leasing arrangements. As of December 31, 2018, the Company had approximately $18.1 million of undiscounted future minimum operating lease commitments that are not recognized on its consolidated balance sheets as determined under the current standard. For a lessee, the results of operations are not expected to significantly change after adoption of the new standard.  While substantially complete, the Company is still in the process of finalizing its evaluation of the effect of ASU 842 on the Company’s financial statements and disclosures, including the determination of the Company’s incremental borrowing rate for each of the operating leases to estimate the interest rate we would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease payments. The Company will finalize its accounting assessment and quantitative impact of the adoption during the first quarter of fiscal year 2019.
In January 2017 the FASB issued ASU No. 2017-4, Intangibles – Goodwill and Other (Topic 350). The amendments in ASU 2017-4 simplify the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, under these amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss should not exceed the total amount of goodwill allocated to that reporting unit. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2019. Early adoption is 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 enters intowould more-likely-than-not reduce the fair value of the reporting unit below its carrying value. During the year ended December 31, 2018, the Company performed its impairment assessment and determined the fair value of the aggregated 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 and, therefore, the Company does not anticipate a lease,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.
In February 2018 the FASB issued ASU No. 2018-2, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-2 was issued to address the income tax accounting treatment of the stranded tax effects within other comprehensive income due to the prohibition of backward tracing due to an income tax rate change that was initially recorded in other comprehensive income due to the enactment of the Tax Cuts and Jobs Act (TCJA) on December 22, 2017, which changed the Company's income tax rate from 35% to 21%. The amendments to the ASU changed US GAAP whereby an entity may elect to reclassify the stranded tax effect from accumulated other comprehensive income to retained earnings. The amendments of the ASU may be adopted in total or in part using a full retrospective or modified retrospective method. The amendments of the ASU are effective for periods beginning after December 15, 2018. The Company believes there will be no material impact to the consolidated financial statements as a result of this update.
In June 2018, the FASB issued ASU No. 2018–07, Improvements to Nonemployee Share–Based Payment Accounting. ASU 2018–07 simplifies the accounting for share–based payments to nonemployees by aligning it with some specified scope exemptions. The guidance in this Update supersedes FASB ASC 840, Leases.the accounting for share–based payments to employees, with certain exceptions. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within thosethat fiscal years.year. The Company is currently assessing the impacteffect of adopting this ASU 2018–02 on its consolidated financial statements and related disclosures.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.

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 7 to the Notes to the Consolidated Financial Statements for more information.

Beginning January 1, 2017, due to 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.
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 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 petrochemical segment
The specialty petrochemical 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 petrochemical 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 Wax segment
The specialty wax 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 specialty petrochemical facility and our specialty synthetic wax facility.

Our specialty petrochemical facility and specialty synthetic wax facility are currently our revenue generating assets. The facilities were in full operation at December 31, 2015.

2018.
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.
32

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 9 to the Notes to the Consolidated Financial Statements for additional information.

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. Any proceeds received from or payments made to AMAK are recorded as decreases or increases in the balance of our investment. See Note 10 to the Notes 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 1514 to the Notes 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 1615 to the Notes 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 “Investment"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, 2015. See Note 1716 to the Notes to the Consolidated Financial Statements.

On 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 permits 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.
Derivative InstrumentsThe 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 of December 31, 2018.

The changes to existing U.S. tax laws as a result of the TCJA, which will have the most significant impact on the Company's federal income taxes are as follows:
We use financial commodity agreements to hedgeReduction of the costU.S. Corporate Income Tax Rate - The Company uses the asset and liability method of natural gasoline, the primary source of feedstock,accounting for income taxes. Under this method, deferred tax assets 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
33

commodity agreements are not designated as hedges; therefore, all changes in estimated fair valueliabilities are recognized in costfor the future tax consequences attributable to differences between the financial statement carrying amounts of petrochemical product salesexisting assets and processingliabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the consolidated statements of income.

On March 21, 2008, SHR entered intoyears in which those temporary differences are expected to reverse. As 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 dateresult of the interestreduction in the U.S. corporate income tax rate swap agreement was August 15, 2008, and terminates on December 15, 2017.  The notional amount offrom 35% to 21% under the interest rate swap was $2.75 millionTCJA, the Company revalued its ending net deferred tax liabilities at December 31, 2015.  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, 2015, and 2014 totaled $0.2 million and $0.4 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.

Item 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, 2015, 20142018, 2017 and 2013,2016, we had approximately $82.3$103.3 million, $80.5$99.6 million and $13.2$84.0 million, respectively, in variable rate debt outstanding.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 $199,000, $215,000$433,000, $405,000 and $30,000$275,000 at December 31, 2015, 20142018, 2017 and 2013,2016, 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 2015,2018, market risk for 20162019 was estimated as a hypothetical 10% increase in the cost of natural gas and feedstock over the market price prevailing on December 31, 2015.2018. Assuming that 20162019 total specialty petrochemical product sales volumes stay at the same rate as 2015,2018, the 10% market risk increase will result in an increase in the cost of natural gas and feedstock of approximately $10.6$11.9 million in fiscal 2016.2019.

Item 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 .disclosure. It should be noted that because of inherent limitations, our disclosure controls and procedures, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objective of the disclosure controls and procedures are met.

As required by paragraph (b) of Rules 13a-15 and 15d-15 under the Exchange Act, our Chief Executive Officer, and Chief Financial Officer have evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded, as of the end of the period covered by this report, that our disclosure controls and procedures were effective at a reasonable assurance level to ensure that the information that we are required to disclose in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure.disclosure because of the material weakness in our internal control over financial reporting described below.

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

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is a process that is designed under the supervision of our Chief Executive Officer and Chief Financial Officer, and effected by our Board of Directors, management and other personnel, to provide assurance regarding the 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 that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States, and that receipts and expenditures recorded by us are being made only in accordance with authorizations of our management and Board of Directors; and
Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.
Internal control over financial reporting has inherent limitations. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of its inherentsuch 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 mayprocess.

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.Reporting. Our responsibility is to express an opinion on the Company’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.

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 andor procedures may deteriorate.

In our opinion, Trecora Resources maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the COSO criteria.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Trecora Resources as of December 31, 2015 and 2014 and the related consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2015, and our report dated March 11, 2016 expressed an unqualified opinion.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation– The consolidated financial statements include the balance sheets, statements of income, comprehensive income, stockholders’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.

Accounts ReceivableTrade Receivables and Allowance for Doubtful Accounts – We evaluate the collectability of our accounts receivabletrade 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 yearsyear ended December 31, 2015, 2014, and 2013,2018, we increased the balance by $152,000 due to concerns regarding collectability for a specific customer. For the year ended December 31, 2017, the allowance balance was not increased. In 2016, we increased the balance by $90,000 due to an increase in sales in countries where there is a greater risk of default and limited recourse should this occur. 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. No amounts were written off in 2015, 20142018 or 2013.2017. During 2016 we wrote off one account for approximately $93,000.

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
F-10

note receivable is recorded with an imputed interest rate. InterestThere were no notes receivable outstanding as of December 31, 2018. The interest rate used on outstanding notes during December 31, 2015,2018 and 2014,2017 was 4%. 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, 20152018 and 2014.

Mineral Exploration and Development Costs - All costs related to the acquisition, exploration, and development of mineral deposits are capitalized until such time as (1) the Company commences commercial exploitation of the related mineral deposits at which time the costs will be amortized, (2) the related project is abandoned and the capitalized costs are charged to operations, or (3) when any or all deferred costs are permanently impaired.  At December 31, 2015, and 2014, our only remaining mining assets were held by PEVM, and we do not foresee them reaching the commercial exploitation stage.  No indirect overhead or general and administrative costs have been allocated to this project.2017, respectively.

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 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,
F-11

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 AMAKsAMAK's financial statements (see Note 10). 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. We consider recoverable ore reserves, changes in commodity prices, and the amount and timing of the cash flows to be generated by the production of those reserves, as well as, recent equity transactions within AMAK.

Other Assets - Other assets include a license used in specialty petrochemical operations, notes receivable, loan origination fees,spare parts inventory and certain specialty petrochemical assets. Beginning January 1, 2017, due to the expansion of our plant assets at SHR and TC, we began inventorying spare parts for the repair and maintenance of our plant, pipeline and equipment. Spare parts are accounted for on the first-in, first-out method (FIFO).

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 petrochemical segment
The specialty petrochemical 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 petrochemical 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 Wax segment

The specialty wax 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 72 years. For years ended December 31, 2015, 2014,2018, 2017, and 2013,2016, matching contributions of approximately $1,116,000, $641,000,$1,502,000, $1,412,000, and $554,000,$1,195,000, 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 $0.8 million, $0.8 million, and $1.0 million, for 2015, $1.6 million for 2014,2018, 2017, and $1.3 million for 2013.2016, respectively.

F-12

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

Foreign Currency - The functional currency for the Company and each of the Company’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, 2015, 20142018, 2017 and 2013,2016, 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;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, 2015, 2014,2018, 2017, and 20132016 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
F-13

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 allowance is recorded if there is uncertainty as to the realization offor a deferred tax assets.

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 material adjustment
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 rate from a maximum of 35 percent to a flat 21 percent 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), made AMT credit carryforwards refundable, and permitted 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 has elected to recognize the income tax effects of the TCJA in its financial statements in accordance with Staff Accounting Bulletin 118 (SAB 118), which provides guidance for the application of ASC Topic 740 Income Taxes, in the liabilityreporting 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 unrecognizedcertain income tax benefits.  Aseffects of December 31, 2015, and 2014,the TCJA it will recognize provisional amounts if a reasonable estimate can be made. If a reasonable estimate cannot be made then no interest or penalties relatedimpact is recognized for the effect of the TCJA. SAB 118 permits an up to uncertain tax positions hadone year measurement period to finalize the measurement of the impact of the TCJA.
Reclassifications – Certain reclassifications have been accrued.made to prior year balances to conform with the current year presentation.

Subsequent Events – The Company has evaluated subsequent events through March 15, 2019, the date that the consolidated financial statements were approved by management.
New Accounting Pronouncements

In May 2014 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, 2014-9, Revenue from Contracts with Customers ("ASU 2014-09"2014-9"). ASU 2014-092014-9 supersedes the revenue recognition requirements of FASB Accounting Standards Codification ("ASC") Topic 605, Revenue Recognitionand most industry-specific guidance throughout the Accounting Standards Codification, resulting in the creation of FASB ASC Topic 606, Revenue from Contracts with Customers. ASU 2014-092014-9 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.TheThe Company is currently assessingcompleted its assessment of the potential impact of adopting thisthe adoption of ASU on its consolidated financial statements2014-9 across all revenue streams. This included reviewing current accounting policies and related disclosures.

In June 2014practices to identify potential differences that would result from applying the FASB issued ASU No. 2014-12, Compensation – Stock Compensation (Topic 718): Accounting for Share-Based Payments Whenrequirements under the Termsnew standard. We completed contract reviews and validated results of an Award Provide That a Performance Target Could Be Achieved afterapplying the Requisite Service Period. The new standard requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 and can be applied either prospectively or retrospectively to all awards outstanding as of the beginning of the earliest annual period presented as an adjustment to opening retained earnings. Early adoption is permitted. The Company is currently assessing the potential impact of adopting this ASU on its consolidated financial statements and related disclosures.

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 measurementrevenue 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(Note 2). 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, andSee Revenue Recognition policy note.

should be applied retrospectively.  Early adoption is permitted. The Company is currently assessing the potential impact of adopting ASU 2015-03 and ASU 2015-15 on its consolidated financial statements and related disclosures.

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 is currently assessing the potential impact of adopting this ASU on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard was issued to This update will increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. This update is effective for annual and interim reporting periods beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. In July 2018, the FASB issued ASU No. 2018-11, Targeted Improvements to ASC 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 affectsprovides a number of optional practical expedients in transition. The Company expects to elect: (1) the ‘package of practical expedients’, which permits 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 provides practical expedients for an entity’s ongoing accounting that the Company anticipates making, such as the (1) the election for certain classes of underlying asset to not separate non-lease components from lease components and (2) the election for short-term lease recognition exemption for all leases that qualify. The Company will adopt ASU 842 as of January 1, 2019, using the alternative modified transition method. In preparation of adopting ASC 842, the Company is implementing additional internal controls to enable future preparation of financial information in accordance with ASC 842. The Company has also substantially completed its evaluation of the impact on the Company’s lease portfolio. The Company believes the largest impact will be on the consolidated balance sheets for the accounting of rail cars, equipment and office leases, which represents a majority of its operating leases it has entered into as a lessee. These leases will be recognized under the new standard as right of use assets (“ROU”) operating lease liabilities. The Company will also be required to provide expanded disclosures for its leasing arrangements. As of December 31, 2018, the Company had approximately $18.1 million of undiscounted future minimum operating lease commitments that are not recognized on its consolidated balance sheets as determined under the current standard. For a lessee, the results of operations are not expected to significantly change after adoption of the new standard.  While substantially complete, the Company is still in the process of finalizing its evaluation of the effect of ASU 842 on the Company’s financial statements and disclosures, including the determination of the Company’s incremental borrowing rate for each of the operating leases to estimate the interest rate we would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease payments. The Company will finalize its accounting assessment and quantitative impact of the adoption during the first quarter of fiscal year 2019.
In January 2017 the FASB issued ASU No. 2017-4, Intangibles – Goodwill and Other (Topic 350). The amendments in ASU 2017-4 simplify the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, under these amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss should not exceed the total amount of goodwill allocated to that reporting

unit. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December 15, 2019. Early adoption is 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 enters intowould more-likely-than-not reduce the fair value of the reporting unit below its carrying value. During the year ended December 31, 2018, the Company performed its impairment assessment and determined the fair value of the aggregated 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 and, therefore, the Company does not anticipate a lease,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.
In February 2018 the FASB issued ASU No. 2018-2, Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. ASU 2018-2 was issued to address the income tax accounting treatment of the stranded tax effects within other comprehensive income due to the prohibition of backward tracing due to an income tax rate change that was initially recorded in other comprehensive income due to the enactment of the Tax Cuts and Jobs Act (TCJA) on December 22, 2017, which changed the Company's income tax rate from 35% to 21%. The amendments to the ASU changed US GAAP whereby an entity may elect to reclassify the stranded tax effect from accumulated other comprehensive income to retained earnings. The amendments of the ASU may be adopted in total or in part using a full retrospective or modified retrospective method. The amendments of the ASU are effective for periods beginning after December 15, 2018. The Company believes there will be no material impact to the consolidated financial statements as a result of this update.
In June 2018, the FASB issued ASU No. 2018–07, Improvements to Nonemployee Share–Based Payment Accounting. ASU 2018–07 simplifies the accounting for share–based payments to nonemployees by aligning it with some specified scope exemptions. The guidance in this Update supersedes FASB ASC 840, Leases.the accounting for share–based payments to employees, with certain exceptions. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within thosethat fiscal years.year. The Company is currently assessing the impacteffect of adopting this ASU 2018–02 on its consolidated financial statements and related disclosures.statements.

NOTE 3 – ACQUISITION OF TRECORA CHEMICAL, INC. (formerly SSI Chusei, Inc.)

B PLANT
On October 1, 2014,May 2, 2016, we acquired 100% ofpurchased the Class A common stock of SSI Chusei, Inc. (“SSI”), a Texas corporationidle BASF facility adjacent to our TC facility in exchange for a$2.0 million in cash, paymenttransaction costs of $74.8 million whichapproximately $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 (i) $4,702,000 from TREC’s existing cash balancesworking capital. The purchased facility includes production equipment similar to TC's plus equipment that broadens TC's capabilities and (ii) $70,000,000 frompotential 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 proceeds of a senior secured financing.    On November 15, 2014, SSI’s name was officially changed to Trecora Chemical, Inc.

TC is a leading manufacturer of specialty synthetic waxes and custom processing services located in Pasadena, Texas.  We believe the Acquisition increases our product diversification, expands our footprint in the industry, and provides geographic diversity.  TC makes up the specialty synthetic wax segment of our business.

facility as "B Plant".
We have accounted for the Acquisitionpurchase in accordance with the acquisition method of accounting under Financial Accounting Standards Board Accounting Standards Codification Topic 805 “Business Combinations” (“"Business Combinations" ("ASC 805”805"). In accordance with ASC 805, we used our best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumedacquired at the Acquisition Date. Goodwill as of the Acquisition Date was measured as the excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired.

acquisition date.
The assets and certain liabilities acquired from TC on October 1, 2014, have been included in our consolidated balance sheets and our consolidated statements of income since the date of acquisition.  The sales and operating loss of TC that are included in the consolidated statements of income for the year ended December 31, 2014, was $5.3 million and $1.1 million, respectively.  In connection with the Acquisition, we incurred acquisition costs of $1.0 million which are reflected in general and administrative expenses in the consolidated statements of income.  The financial results of TC’s business are reported as a separate business segment.

NOTE 4 - 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 year ended December 31, 2015,2018, one customer accounted for 20.1%17.0% of totalconsolidated product revenue. For the year ended December 31, 2014, two customers2017, one customer accounted for 23.2% and 10.5%19.6% of totalconsolidated product revenue. For the year ended December 31, 2013, two customers2016, one customer accounted for 16.5% and 16.2%20.1% of totalconsolidated product sales.revenue. The associated accounts receivable balances for those customers were approximately $7.6$11.0 million at December 31, 2015,2018, and $9.5$5.8 million and $1.6 million as ofat December 31, 2014.2017. The carrying amount of accounts receivable approximates fair value at December 31, 2015.

2018, and 2017.
Accounts receivable serves as collateral for our amended and restated loan agreement (see Note 12).

We market our products in many foreign jurisdictions. For the years ended December 31, 2015, 20142018, 2017 and 2013,2016, specialty petrochemical product sales revenue in foreign jurisdictions accounted for approximately 27.9%35.4%, 30.5%20.8%, and 26.2%,23.5% of total product sales revenue, respectively.

SHR utilizes one major supplier for its feedstock supply. The feedstock is a commodity product commonly available from other suppliers if needed. The percentage of feedstock purchased from the supplier during 2015, 2014,2018, 2017, and 20132016 was 100%, 100%100.0% and 99%, respectively. At December 31, 2015,2018, and 2014,2017, we owed the supplier approximately $2.5$4.7 million and $1.0$8.5 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 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 valueexpansion of our cashplant assets at SHR and cash equivalents, trade receivables,  taxes receivable, accounts payable, accrued liabilities, accrued liabilities in Saudi Arabia, other liabilitiesTC, we began inventorying spare parts for the repair and variable rate long term debt.  The fair valuemaintenance 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.

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.

F-17

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, 2015, we had no derivative contracts outstanding.  At December 31, 2014, we had derivative contracts with settlement dates through January 2015.  For additional information see Note 22.

Interest Rate Swaps

In March 2008 we entered into an interest rate swap agreement with Bank of America related to the $10.0 million term loan secured byour plant, pipeline and equipment. The interest rate swap was designedPrepaid catalyst has been reclassified into Plant, Pipeline & Equipment to minimizeconform to current year reporting.

Inventory serves as collateral for our amended and restated loan agreement with a cash flow hedge under ASC Topic 815domestic bank (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 determination12).
Inventory included products in transit valued at approximately $4.1 million 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 for the year ended December 31, 2014.

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).

The following items are measured at fair value on a recurring basis$3.7 million at December 31, 20152018, and 2014:2017, respectively.

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 inventoryCatalyst amortization relating to the LIFO value.
At December 31, 2015platinum catalyst which is included in cost of sales was approximately $59,000, $25,000 and 2014, the LIFO value of inventory exceeded FIFO; therefore, in accordance with the above policy, no LIFO reserve was recorded.

In 2016 the difference between our effective share of income (loss) from our investment and our actual ownership percentage is attributable to the change in our ownership percentage during the third quarter of 2016.
A gain of approximately $16.2 million for the difference between our initial investment in AMAK and our share of AMAK’sAMAK's initial assets recorded at fair value was not recognized in 2008. This basis difference is being amortized over the life of AMAK’s 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’sAMAK's income or loss.

In December 2012 the Board of Directors ofJuly 2016 AMAK authorized the issuance of additional shares of AMAK in an amount equal to ten percent of the then outstandingissued four million shares to raiseprovide additional funds for working capital requirementsongoing exploration work and retirement of construction debt.  In January 2013 we entered into an agreement with AMAK to purchase an additional 937,500mine start-up activities. Arab Mining Co. ("Armico") purchased 3.75 million shares of AMAK at 30 Saudi Riyals (USD $8.00)SR 20 per share (USD 5.33 per share) and the remaining 250,000 shares are for a total of USD $7.5 million.  Due to the continued improvementfuture use as employee incentives. We did not participate in the operations of AMAK and a desire to prevent a substantial dilution of its investment, we elected to purchase these additional shares.  As a result of this purchase and upon completion of the raise on May 27, 2013,offering, thereby reducing our ownership percentage in AMAK became approximately 35%.  All existing AMAK shareholders had the opportunity to buy into the issue and all shares were placed within that group.33.44% from 35.25%. As a result of the equity raise in 2013, the Company’sissuance, our share of the net assets of AMAK increased approximately $4.0$3.2 million which the Companywe recognized as a gain (with a corresponding increase in itsour investment) in accordance with ASC 323-10-40-1.
In 2018, we completed an exchange of shares with certain shareholders whereby such shareholders traded 65,000 common shares of TREC in exchange for 24,489 shares of our AMAK stock.  The 65,000 shares were accounted for as treasury stock.  This transaction reduced our ownership percentage from 33.44% to 33.41%.

The following table shows AMAK shareholders and percentages owned at December 31, 2018:
NamePercentage Owned
Various Saudi shareholders46.73%
Trecora Resources33.41%
Armico19.86%
Total100.00%
As previously announced, AMAK initiated a share repurchase program from its existing shareholders in December 2018. We participated in this share repurchase and received approximately $5.3 million in proceeds from AMAK. We had previously reported, based on information available at the time, that AMAK was repurchasing 10% of its outstanding shares from its existing shareholders on a pro-rata basis. We have since learned that, while a redemption of up to 10% of AMAK's 82 million outstanding shares had been approved by the shareholders, the repurchase program approved by AMAK's board of directors and initiated in December 2018 was with respect to 2.5 million shares. AMAK expects to complete the share repurchase program in 2019, at which point all shares repurchased from AMAK shareholders will be registered as treasury shares. Upon completion of the share repurchase program, the Company does not believe its ownership percentage in AMAK will change from 33.4%.
At December 31, 2018 and 2017, we had a receivable from AMAK of approximately $54,000 and $121,000, respectively, relating to unreimbursed travel and Board expenses which is included in prepaid and other assets.
We assess our investment in AMAK for impairment when events are identified, or there are changes in circumstances that may have an adverse effect on the fair value or recoverability of the investment. We consider recoverable ore reserves and the amount and timing of the cash flows to be generated by the production of those reserves, as well as, recent equity transactions within AMAK. No impairment charges were recorded in 2015, 2014,2018, 2017, or 2013.2016.

NOTE 1514 - COMMITMENTS AND CONTINGENCIES

Guarantees
Guarantees

On October 24, 2010, we executed a limited guarantee in favor of the Saudi Industrial Development Fund (“SIDF”("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”"Loan"). The term of the loan is currently through June 2019.2022. As a condition of the Loan, SIDF required all shareholders of AMAK to execute personal or corporate guarantees; as a result, the Company’sCompany'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 wasis 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

The Company has recognized the provisional tax impacts related to the acceleration of depreciation and included these amounts in its consolidated financial statements for the year ended December 31, 2018. After the analysis, the Company did not identify items for which the income tax effects of the TCJA have not been completed and a reasonable estimate could not be determined as of December 31, 2018.
The changes to existing U.S. tax laws as a result of the TCJA, which will have the most significant impact on the Company's federal income taxes are as follows:
Reduction of the U.S. Corporate Income Tax Rate - The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the TCJA, the Company revalued its ending net deferred tax liabilities at December 31, 2017.
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.

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:

NOTE 2120 – RELATED PARTY TRANSACTIONS

Consulting fees of approximately $25,000, $52,000$28,000, $27,000 and $98,000$33,000 were incurred during 2015, 2014,2018, 2017, and 2013,2016, respectively from IHS Global FZ LLC of which Company Director Gary K.

NOTE 21 – RESTRUCTURING AND SEVERENCE EXPENSES
During 2018, the Company incurred restructuring and severance expenses of approximately $2.3 million related to changes in feedstockexecutive management and natural gas prices.  Not considering derivative transactions, feedstockthe completion of projects in our specialty petrochemical segment. These expenses relate to severance, stock compensation for continued vesting of time-vested shares issued under the Company's long-term incentive plans, and natural gas used for the years endedcertain employee benefits including medical insurance and vacation. As of December 31, 2015, 2014,2018, approximately $1.2 million remains unpaid and 2013, represented approximately 69.3%, 78.0% and 80.6% of SHR’s operating expenses, respectively.is included in accrued liabilities.

On February 26, 2009, the Board of Directors rescinded its original commodity trading resolution from 1992 and replaced it with a new resolution.  The 2009 resolution allows the Company to establish a commodity futures account 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 out 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 all of the derivatives transactions taking place are authorized and in accord with the policies and strategies that have been enacted.  On August 31, 2009, the Company adopted a formal risk management policy which incorporates the above process, as well as, established a “hedge committee” for derivative oversight.

We endeavor to acquire feedstock and natural gas at 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 Swaps

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 $2.75 million at December 31, 2015.  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.

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

Due to the new debt agreements associated with the Acquisition, we 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.

NOTE 23-22- POST-RETIREMENT OBLIGATIONS

In January 2008, an amended retirement agreement replacing the February 2007 agreement, was entered into with Mr. 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 $911,000 based upon an annuity single premium value contract was outstanding at December 31, 2015, and was included in post-retirement benefits.  Mr. El Khalidi retired effective June 30, 2009.  As of December 31, 2015, no payments have been made pursuant to this agreement.

F-36

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, 2015, and was included in post-retirement benefits.

OnKhalidi; however, on May 9, 2010, the Board of Directors terminated the retirement agreement options, retirement bonus, and any outstanding directors’ fees due to actions of Mr. El Khalidi; however, due to the litigation discussed inKhalidi. See Note 15, all14. All amounts remain outstandingwhich had not met termination dates remained recorded until a resolution iswas achieved. The matter was resolved on May 25, 2018 and as of June 30, 2018, post-retirement obligations of approximately $1.0 million for Mr. El Khalidi have been reversed. As of December 31, 2017, approximately $1.0 million remained outstanding and was included in post-retirement benefits.


F-37


In July 2015 and June 2018, we entered into retirement agreements with our former CEO, Nicholas Carter, and our former VP of Accounting & Compliance, Connie Cook. Mr. Carter's agreement provides continued welfare benefits for him and his wife for life at the same cost sharing basis as regular employees. Ms. Cook's agreement provides continued welfare benefits for her and her husband until eligible for Medicare. Approximately $377,000 and $249,000 was outstanding at December 31, 2018, and 2017, respectively, and included in post-retirement benefits. For the period ended December 31, 2018, and 2017, approximately $18,000 and $16,000, respectively had been paid.

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.

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. We expect to resume operations in the fourth quarter of 2016. In February 2016, we entered into a new operating and rehabilitation contract under more favorable terms.

Note 1 – Organization and Business – (Continued)

DuringOur focus during the renovation our focus remainsfocused 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 may beginFebruary 2016, we entered into a new operating and rehabilitation contract with a different vendor under more favorable terms.

We resumed operations in the secondfirst quarter of 2016. An additional exploration program2017 and generated enough ore for the resttwo shipments in 2017. In 2018, we resumed our schedule of the Guyan mining lease will commence shortly.4 shipments a year.


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:

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 6, 2016, the date on which the financial statements were available to be issued.

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, 2015, 2014,2018, 2017, and 2013,2016, we sold our concentrates and doré pursuant to a sales contract with one customer. No amounts have been written off for the years ended December 31, 2015, 2014,2018, 2017, and 2013.2016. In addition, we determined that an allowance for doubtful accounts was not necessary at December 31, 20152018 and 2014.

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

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.

- 11 -


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.

WeBased on our evaluation, we recorded no impairment losses during the years ended December 31, 2015, 20142018, 2017 and 2013.2016.

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.

Pre-export Advances
- 12 -


Note 2 - SummaryAt times we receive advances on a pre-export basis against a portion of Significant Accounting Policies - (Continued)

Deferred finance costs
Deferred finance costsour inventory on hand prior to shipment. These advances bear interest at 2.5% and are primarily comprised ofrepaid from the Saudi Industrial Development Fund (SIDF) loan origination charges which are amortized over the period of the related loan which approximates the interest method. Deferred finance costs are shown net of accumulated amortization of SR13,399,433 and SR11,251,789proceeds from final concentrate sales. We did not have an outstanding advance liability at December 31, 20152018 and 2014, respectively. Amortization expense of deferred finance costs was approximately SR2,148,000, SR2,622,000, and SR3,166,000 for the years ended December 31, 2015, 2014, and 2013, respectively.2017.

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, 2015, 2014,2018, 2017, and 2013.2016.

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, 2015, we had no outstanding capital lease obligations.

Operating lease expense amounted to approximately SR696,000, SR867,000,SR1,619,000, SR1,454,000 and SR456,000SR442,000 for the years ended December 31, 2015, 20142018, 2017 and 2013,2016, 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.


- 13 -

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

Asset retirement obligations and costs
We record the fair value of our estimated asset retirement obligations (AROs) associated with tangible long-lived assets in the period in which the obligation is incurred. AROs associated with long-lived assets are those for which there is a legal obligation to settle under various laws, statues, or regulations. These obligations, which are initially estimated based on discounted cash flow estimates, are accreted to full value over time through charges to cost of revenues. In addition, asset retirement costs (ARCs) are capitalized as part of the related asset’s carrying value and are depreciated (primarily on a unit-of-production basis) over the asset’s respective useful life. 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 DirectorateGeneral Authority of Zakat and Income Tax (DZIT)(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 and income tax returns for the years from 20092010 to 20142017 are currently under review with DZIT.

Reclassifications
Certain reclassifications have been made to the prior periods to conform with current year presentation.

Revenue recognition
We sell our products pursuant to sales contracts entered into with a customer who acts as an intermediary and resells our products to end users. Revenue is recognized when title and risk of loss pass to the customer and when collectability is reasonably assured. The passing of title and risk of loss to the customer is based on terms of the sales contract, generally upon shipment or delivery of product.

Sales are recorded based on a provisional sales price or a final sales price calculated in accordance with the terms specified in the relevant sales contract. Under the long-established structure of sales agreements prevalent in the industry, the copper and zinc contained in concentrate is generally “provisionally”provisionally priced at the time of shipment. The provisional price received at the time of shipment is later adjusted to a “final”final price based on quoted monthly average spot prices on the London Metal Exchange (LME) for a specified future month. We record revenues at the time of shipment (when title and risk of loss pass) based on then-current LME prices, and we account for any changes between the sales price recorded at the time of shipment and subsequent changes in the LME prices through the date of final pricing as gains or losses from a derivative embedded in the sales contract (a futures contract initiated at the date of shipment and settled upon the determination of the “final price”)final price) which is bifurcated and separately accounted for at fair value. See Note 17.16.

Revenues from concentrate sales are recorded net of treatment and refining charges. These allowances are a negotiated term of each contract. Treatment and refining charges represent payments or price adjustments to smelters and refiners and are either fixed, or in certain cases, vary with the price of metals (referred to as price participation).

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

Management estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The most significant areas requiring the use of management estimates include mineral reserve estimation; useful asset lives for depreciation and amortization; zakat and income taxes; environmental obligations; reclamation and closure costs; estimates of recoverable materials in mill stockpiles; fair value of embedded derivatives; end-of-service indemnities; and

asset impairment, including estimates used to derive future cash flows associated with those assets. Actual results could differ from these estimates.

Recent accounting pronouncements
In May 2014 the Financial Accounting Standards Board (FASB)("FASB") issued Accounting Standards Update (ASU)("ASU") 2014-09, Revenue from Contracts with Customers (ASU 2014-09)("ASU 2014-09"). ASU 2014-09 supersedes the revenue recognition requirements of FASB Accounting Standards Codification (ASC)("ASC") Topic 605, Revenue Recognition and most industry-specific guidance throughout the ASC,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. ThisFor nonpublic companies this ASU provides alternative methods of retrospective adoption and is effective for fiscal years and interim periods within those years, beginning after December 15, 2017. Early adoption would be permitted but not before annual periods beginning after December 15, 2016.The Company is currently assessing the potential impact of adopting this ASU on its financial statements and related disclosures.

In April 2015 the FASB issued ASU 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 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

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

Recent accounting pronouncements – continued
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.2018. Early adoption is permitted. The Company is currently assessingevaluating the potential impact of adoptingthese amendments, although it does not expect the amendments to have a significant impact to the Company’s financial position or results of operation.

In February 2016 the FASB issued ASU 2015-03No. 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 2015-15 onis effective for fiscal years beginning after December 15, 2019, 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. 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 reviewing the amendments to ensure it is fully compliant by the adoption date and 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 and related disclosures.for matters requiring recognition or disclosure in the financial statements. The accompanying financial statements consider events through March 6, 2019, 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 twothree consecutive years of net losses however, the Company resumed full operations and had a negative marginoperating income and cash provided from operations during the year ended December 31, 2018. In addition, we expect to update our mineral resources and life of mine in 2015. Our losses were largely attributable to2019 with the depressed commodity prices as well as certain operating inefficiencies from our operating contract with CGM. In response to these factors, we took certain steps to protectexpectation that the Company and the shareholders. We renegotiated our debt repayment arrangement with SIDF and postponed any repayments until 2017. We cancelled the operating contract with CGM and suspended operations until the fourth quarterlife of 2016. In February 2016, we entered into a new operating and rehabilitation contract under more favorable terms. During our shutdown we plan to renovate our facilities to improve recoveries and reduce costs and explore options to possibly self-operate the facilities which is expected to improve profitability.mine will be extended another two years. We believe that our continued operations and the cash on hand, liquidationadjusted repayment terms of our remaining inventories, and the processing of the Guyan gold dumps will fund our operations until the facilities are back online in late 2016. The final length of the shutdown period ultimately depends on the cash available and the completion of the renovation work planned.  The mill may resume operations at any time after the new operators are in place and any remaining renovations may be completed while operating if necessary. Warehouse financing is readily available once operations resume, and no capital call on existing shareholders is anticipated.

We believe that the items discussed aboveoutstanding debt 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 included 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).


Note 9 – Pre-export Advance PaymentsThe MOU’s were binding agreements between the Company, CGM and Nesma. All of CGM’s spare parts on site related to the Contracts reverted to and became 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 SR34,477,500. The spare parts were recorded at SR4,500,000 and were included in property and equipment, net on the balance sheets. Under the MoU’s, CGM and Nesma did not receive any further payments from the Company as full settlement against the deterioration of property, plant and equipment which exceeded normal wear and tear and any other breach of contracts. In recognition of certain financial losses incurred by the Company, CGM and NESMA forfeited 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 were no outstanding or unresolved claims and all parties have fulfilled their obligations in connection with the Contracts.

During 2015 and 2014, 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 had an outstanding advance liability of approximately SR9,151,000 and SR3,823,000 at December 31, 2015 and 2014.

Note 15 - Fair Value Measurement
- 25 -


Note 17 Embedded DerivativesFair 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).

As described
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 Noteor out of Levels 1, 2, under “Revenue Recognition,”or 3 in 2018 or 2017. The embedded derivatives in our concentrateprovisional sales contracts provide for provisional pricing based on the LME price at the time of shipment as specified in the contract.  Sales contracts with a provisional sales price contain an embedded derivative (i.e., the price settlement mechanism that is settled after the time of delivery) that is required to be bifurcated from the host contract. The host contract is the sale of the metals contained in the concentrates at the then-current LME price as defined in the contract. Mark-to-market price fluctuations recorded through the settlement date are reflected in revenues for sales contracts. Our embedded derivatives at December 31, 2015, were not significant to the financial statements.considered Level 2 measurements.
