Amendment Description	Trecora Resources (the “Company”) is filing this Amendment No. 1 on Form 10-Q/A (“Amendment No. 1”) in order to correct its share of earnings of Al Masane Al Kobra Mining Co. (“AMAK”), a Saudi Arabian closed joint stock company in which the Company has an investment accounted for by the equity method. Restatement of Consolidated Financial Statements The unaudited consolidated statements of income for the three and six months ended June 30, 2016, have been restated to properly reflect the Company’s equity in earnings of AMAK for that three and six month period, the unaudited consolidated balance sheet as of June 30, 2016, has been restated to reflect the effect of correcting the error on the balance of the investment in AMAK, and the unaudited consolidated statements of stockholders’ equity and cash flows and the notes to the unaudited consolidated financial statements have been restated to make the associated changes required by the adjustments described above. For a discussion of the equity in earnings of AMAK and the accounting errors identified, see “Part I, Item 2—Management’s Discussion and Analysis of Financial Condition and Results of Operations—AMAK Review and Restatement” and Note 3 of Notes to Consolidated Financial Statements (Unaudited) included in “Part I, Item 1—Financial Statements.” Management’s Discussion and Analysis of Financial Condition and Results of Operations In addition, changes necessitated by the restatement of the Company’s June 30, 2016, unaudited consolidated financial statements have been made in Part I, Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations. Disclosure Controls and Procedures and Internal Control Over Financial Reporting Management reassessed its evaluation of the effectiveness of disclosure controls and procedures and our internal control over financial reporting as of June 30, 2016, and as of September 30, 2016, and concluded that a deficiency in the design and operating effectiveness of our internal controls represents a material weakness in our internal control over financial reporting and, therefore, that we did not maintain effective disclosure controls and procedures or internal control over financial reporting as of June 30, 2016, and September 30, 2016. For a description of the material weakness identified by management and management’s plan to remediate the material weakness, see “Part I, Item 4 — Controls and Procedures.” Risk Factors An additional risk factor has been added in Part II, Item 1A – Risk Factors. Amended Reports We are concurrently filing an Amended Quarterly Report on Form 10-Q/A for the fiscal quarter ended September 30, 2016, that reflects the effects of the restatement in this Amended Quarterly Report on Form 10-Q/A as well as a restatement for an additional error relating to AMAK affecting the fiscal quarter ended September 30, 2016. Except as set forth above, no other material changes have been made from the originally filed Quarterly Report on Form 10-Q for the three and six months ended June 30, 2016, and except as set forth above this Amendment No. 1 speaks as of the date of the original filing of the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2016, and does not reflect events that may have occurred subsequent to the date of the original filing on Form 10-Q. This Amended Quarterly Report on Form 10-Q/A reflects amendments to the following items: • Part I, Item 1 — Financial Statements • Part I, Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of Operations • Part I, Item 4 — Controls and Procedures • Part II, Item 1A — Risk Factors • Part II, Item 6 — Exhibits The Company’s Chief Executive Officer and Chief Financial Officer are providing currently dated certifications in connection with this Amended Quarterly Report on Form 10-Q/A. See Exhibits 31.1, 31.2, 32.1 and 32.2.

Our principal business activities are the manufacturing of various specialty hydrocarbons and synthetic waxes and the provision of custom processing services. Unless the context requires otherwise, references to “we,” “us,” “our,” and the “Company” are intended to mean Trecora Resources and its subsidiaries. This document includes the following abbreviations: (1) TREC – Trecora Resources (2) TOCCO – Texas Oil & Chemical Co. II, Inc. – Wholly owned subsidiary of TREC and parent of SHR and TC (3) SHR – South Hampton Resources, Inc. – Petrochemical segment and parent of GSPL (4) GSPL – Gulf State Pipe Line Co, Inc. – Pipeline support for the petrochemical segment (5) TC – Trecora Chemical, Inc. – Specialty wax segment (6) AMAK – Al Masane Al Kobra Mining Company – Mining equity investment – 35% ownership (7) PEVM – Pioche Ely Valley Mines, Inc. – Inactive mine - 55% ownership Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, these unaudited financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and, therefore, should be read in conjunction with the financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The unaudited condensed financial statements included in this document have been prepared on the same basis as the annual condensed financial statements and in management’s opinion reflect all adjustments, including normal recurring adjustments, necessary to present fairly the Company’s financial position, results of operations and cash flows for the interim periods presented. We have made estimates and judgments affecting the amounts reported in this document. The actual results that we experience may differ materially from our estimates. In the opinion of management, the disclosures included in these financial statements are adequate to make the information presented not misleading. Operating results for the three and six months ended June 30, 2016, are not necessarily indicative of results for the year ending December 31, 2016. We currently operate in two segments, specialty petrochemical products and specialty synthetic waxes. All revenue originates from United States’ sources, and all long-lived assets owned are located in the United States. In addition the Company owns a 35% interest in AMAK, a Saudi Arabian closed joint stock company which owns, operates and is developing mining assets in Saudi Arabia. We account for our investment under the equity method of accounting. See Note 17 and 20. Certain reclassifications have been made to the Statements of Income for the three and six months ended June 30, 2015, in order to conform to the three and six months ended June 30, 2016, presentation. These reclassifications had no effect on net income for the three and six months ended June 30, 2015, as previously reported. Certain reclassifications have been made to the Consolidated Balance Sheets for the year ended December 31, 2015, related to our adoption of ASU 2015-03 and ASU 2015-15 as noted below in Note 2.

RECENT ACCOUNTING PRONOUNCEMENTS [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	2. RECENT ACCOUNTING PRONOUNCEMENTS In May 2014 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers . Revenue Recognition Revenue from Contracts with Customers efore annual periods beginning after December 15, 2016. In April 2015 the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. 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. In November 2015 the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes 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. In February 2016 the FASB issued ASU No. 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). The ASU is effective for fiscal years beginning after December 15, 2018, 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. In March 2016 the FASB issued ASU No. 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting , which will reduce complexity in accounting standards related to share-based payment transactions, including, among others, (1) accounting for income taxes, (2) classification of excess tax benefits on the statement of cash flow, (3) forfeitures, and (4) statutory tax withholding requirements. The ASU is effective for annual reporting periods beginning on or after December 15, 2016, and interim periods within those annual periods.

RESTATEMENT OF FINANCIAL STATEMENTS [Abstract]
RESTATEMENT OF FINANCIAL STATEMENTS	3. RESTATEMENT OF UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS The accompanying unaudited consolidated financial statements as of and for the three and six months ended June 30, 2016, have been restated to properly reflect our equity in the earnings of AMAK for that three and six month period. In the originally issued unaudited financial statements as of and for the three and six months ended June 30, 2016, we recorded our share of the earnings of AMAK based upon the interim statements as received from AMAK. AMAK had originally recorded a gain of approximately $9.2 million during the three months ended June 30, 2016, as recognition of spare part inventory that was acquired as part of the settlement with its former operator. It has now been determined the accounting for this transaction was incorrect. There was no gain from the assumption of spare parts. However, there was an additional gain on the settlement with the former operator of approximately $1.2 million. Accordingly, we have restated our unaudited consolidated financial statements as of and for the three and six months ended June 30, 2016, to correctly reflect this change to AMAK's financial statements in our equity in earnings from AMAK. The effects of the restatement are as follows: June 30, 2016 (unaudited) As Reported As Restated (thousands of dollars) Consolidated Balance Sheets Investment in AMAK $ 54,865 $ 52,047 Total Assets 279,652 276,834 Deferred Income Taxes 23,856 22,870 Total Liabilities 116,673 115,687 Retained Earnings 108,326 106,494 Total Trecora Resources Stockholders’ Equity 162,690 160,858 Total Equity 162,979 161,147 Total Liabilities and Equity 279,652 276,834 Three Months Ended June 30, 2016 Six Months Ended June 30, 2016 (unaudited) As Reported As Restated As Reported As Restated (thousands of dollars) Consolidated Statements of Income Equity in earnings (loss) of AMAK $ 1,801 $ (1,017 ) $ 7,168 $ 4,350 Total other income (expense) 12,866 10,048 17,592 14,774 Income before income taxes 18,762 15,944 29,633 26,815 Income tax expense 6,678 5,692 10,325 9,339 Net income attributable to Trecora Resources 12,084 10,252 19,308 17,476 Basic earnings per common share (dollars) $ 0.49 $ 0.42 $ 0.79 $ 0.72 Diluted earnings per common share (dollars) $ 0.48 $ 0.41 $ 0.77 $ 0.70 June 30, 2016 (unaudited) As Reported As Restated (thousands of dollars) Consolidated Statement of Stockholders’ Equity Net Income $ 19,308 $ 17,476 Retained Earnings 108,326 106,494 Total 162,690 160,858 Total Equity 162,979 161,147 Consolidated Statements of Cash Flows Operating Activities Net income $ 19,308 $ 17,476 Deferred income taxes 7,462 6,476 Equity in (earnings) loss of AMAK (7,168 ) (4,350 )

INVENTORIES Inventories include the following: June 30, 2016 December 31, 2015 (thousands of dollars) Raw material $ 2,957 $ 2,905 Work in process 18 56 Finished products 17,089 12,843 Total inventory $ 20,064 $ 15,804 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 LIFO value exceeds the FIFO value). In the latter case, in order to ensure that inventory is reported at the lower of cost or market and in accordance with ASC 330-10, we do not increase the stated value of our inventory to the LIFO value. At June 30, 2016, and December 31, 2015, LIFO value of petrochemical inventory exceeded FIFO; therefore, in accordance with the above policy, no LIFO reserve was recorded. Inventory serves as collateral for our amended and restated credit agreement. See Note 10. Inventory included petrochemical products in transit valued at approximately $2.2 million and $2.7 million at June 30, 2016, and December 31, 2015, respectively.

ACQUISITION OF BASF FACILITY [Abstract]
ACQUISITION OF BASF FACILITY	7. ACQUISITION OF BASF FACILITY On May 2, 2016, we purchased the idle BASF facility adjacent to our TC facility in exchange for $2.0 million in cash, transaction costs of approximately $11,000 plus an earnout provision calculated through calendar year 2020 based upon revenue generated by the facility but limited to $1.8 million. The cash payment was funded by working capital. The purchased facility includes production equipment similar to TC’s plus equipment that broadens TC's capabilities and potential markets. The 6.5-acre site also includes substantial storage capacity, several rail and truck loading sites and utility tie-ins to TC. The facility began operations in June 2016 in a limited capacity. We have accounted for the purchase in accordance with the acquisition method of accounting under Financial Accounting Standards Board Accounting Standards Codification Topic 805 “Business Combinations” (“ASC 805”). In accordance with ASC 805, we used our best estimates and assumptions to assign fair value to the tangible assets and liabilities acquired at the acquisition date. These estimates are provisional and may be adjusted in future filings. The assets and liabilities acquired have been included in our consolidated balance sheets and our consolidated statements of income since the date of acquisition. We recorded an $11.5 million bargain purchase gain on the transaction as calculated in the table below (in thousands). Cash paid $ 2,011 Estimated earnout liability 733 Purchase Price $ 2,744 Fixed assets at FMV Land 980 Site improvements 30 Buildings 1,350 Production equipment 11,933 14,293 Bargain purchase gain $ 11,549 The business acquired has been idle for the periods presented thus proforma financial presentation would be identical to our consolidated results. We began operating the new facility in June 2016.

LIABILITIES AND LONG-TERM DEBT [Abstract]
LIABILITIES AND LONG-TERM DEBT	10. LIABILITIES AND LONG-TERM DEBT On October 1, 2014, we entered into an Amended and Restated Credit Agreement (“ARC”) with the lenders which from time to time are parties to the ARC and Bank of America, N.A., as Administrative Agent for the Lenders, and Merrill Lynch, Pierce, Fenner & Smith Incorporated as Lead Arranger. Under the ARC, we may borrow, repay and re-borrow revolving loans from time to time during the period ending September 30, 2019, up to but not exceeding $40.0 million. All outstanding loans under the revolving loans must be repaid on October 1, 2019. As of June 30, 2016, and December 31, 2015, there was a long-term amount of $1.0 million outstanding. The interest rate on the loan varies according to several options. Interest on the loan is paid monthly and a commitment fee of 0.37% is due quarterly on the unused portion of the loan. At June 30, 2016, approximately $39.0 million was available to be drawn; however, in order to maintain compliance with our covenants, approximately $23.5 million may be drawn. Under the ARC, we also borrowed $70.0 million in a single advance term loan (the “Acquisition Loan”) to partially finance the acquisition of TC. Interest on the Acquisition Loan is payable quarterly using a ten year commercial style amortization. Principal is also payable on the last business day of each March, June, September and December in an amount equal to $1,750,000, provided that the final installment on the September 30, 2019, maturity date shall be in an amount equal to the then outstanding unpaid principal balance of the Acquisition Loan. At June 30, 2016, there was a short-term amount of $7.0 million and a long-term amount of $50.8 million outstanding. At December 31, 2015, there was a short-term amount of $7.0 million and a long-term amount of $54.3 million outstanding. Under the ARC, we also had the right to borrow $25.0 million in a multiple advance loan (“Term Loans”). Borrowing availability under the Term Loans ended on December 31, 2015. The Term Loans converted from a multiple advance loan to a “mini-perm” loan once certain obligations were fulfilled 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. Interest on the Term Loans is paid monthly. At June 30, 2016, there was a short-term amount of $1.3 million and a long-term amount of $18.0 million outstanding. At December 31, 2015, there was a short-term amount of $1.3 million and a long-term amount of $18.7 million outstanding. Debt issuance costs of approximately $0.9 million and $1.2 million for the periods ended June 30, 2016 and December 31, 2015, have been netted against outstanding loan balances per ASU 2015-03 and ASU 2015-15. The interest rate on all of the above loans varies according to several options as defined in the ARC. At June 30, 2016, and December 31, 2015, the rate was 2.71% and 2.42%, respectively. We were in compliance with all covenants at June 30, 2016.

FAIR VALUE MEASUREMENTS [Abstract]
FAIR VALUE MEASUREMENTS	11. FAIR VALUE MEASUREMENTS The following items are measured at fair value on a recurring basis subject to disclosure requirements of ASC Topic 820 at June 30, 2016, and December 31, 2015: Assets and Liabilities Measured at Fair Value on a Recurring Basis Fair Value Measurements Using June 30, 2016 Level 1 Level 2 Level 3 (thousands of dollars) Liabilities: Interest rate swap $ 122 - $ 122 - Fair Value Measurements Using December 31, 2015 Level 1 Level 2 Level 3 (thousands of dollars) Liabilities: Interest rate swap $ 177 - $ 177 - The carrying value of cash and cash equivalents, trade receivables, 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 reflects 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, accounts payable, accrued liabilities, other liabilities and variable rate long term debt. The fair value of the derivative instruments are described below. 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 plant). 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 June 30, 2016, and December 31, 2015, no commodity financial instruments were outstanding. For additional information see Note 12. Interest Rate Swap In March 2008 we entered into an interest rate swap agreement with Bank of America related to a $10.0 million term loan secured by plant, pipeline and equipment. The interest rate swap was designed to minimize the effect of changes in the London InterBank Offered Rate (“LIBOR”) rate. We had designated the interest rate swap as a cash flow hedge under ASC Topic 815, Derivatives and Hedging; however, due to the ARC, we felt 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 it as ineffective as of October 1, 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). We have consistently applied valuation techniques in all periods presented and believe we have obtained the most accurate information available for the types of derivative contracts we hold. See discussion of our derivative instruments in Note 12.

DERIVATIVE INSTRUMENTS [Abstract]
DERIVATIVE INSTRUMENTS	12. DERIVATIVE INSTRUMENTS Commodity Financial Contracts Hydrocarbon based manufacturers, such as the Company, are significantly impacted by changes in feedstock and natural gas prices. Not considering derivative transactions, feedstock and natural gas used for the six months ended June 30, 2016, and 2015, represented approximately 61.2% and 69.2% of our petrochemical operating expenses, respectively. The significant percentage decrease of petrochemical operating expenses illustrates the impact that feedstock price changes have on our operations. During the first quarter of 2016, feedstock prices declined industry-wide but rebounded slightly in the second quarter of 2016. We endeavor to acquire feedstock and natural gas at the lowest possible cost. Our 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 or speculative purposes and hedging is limited by our risk management policy to a maximum of 40% of monthly feedstock requirements. Typically, financial contracts are not designated as hedges. As of June 30, 2016, we had no outstanding committed financial contracts. The following tables detail (in thousands) the impact the agreements had on the financial statements: Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 Unrealized gain (loss) $ - $ - $ - $ 180 Realized gain (loss) - - - (180 ) Net gain $ - $ - $ - $ - The realized and unrealized gains/(losses) are recorded in Cost of Sales and Processing for the periods ended June 30, 2016, and 2015. As a percentage of Cost of Sales and Processing, realized and unrealized gains/(losses) accounted for 0% for the three and six months ended June 30, 2016, and 2015. Interest Rate Swap In March 2008, we entered into a pay-fixed, receive-variable interest rate swap agreement with Bank of America related to a $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 $2.25 million and $2.75 million at June 30, 2016, and December 31, 2015, respectively. 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 table shows (in thousands) the impact the agreement had on the financial statements: June 30, 2016 December 31, 2015 Fair value of interest rate swap - liability $ 122 $ 177 Due to the ARC discussed in Note 10, we believe that the hedge is no longer entirely effective; therefore, we began treating the interest rate swap as ineffective at that point. The changes in fair value are now recorded in the Statement of Income. For the three months ended June 30, 2016, an unrealized loss of approximately $8,000 and a realized loss of approximately $33,000 were recorded. For the six months ended June 30, 2016, an unrealized loss of approximately $14,000 and a realized loss of approximately $70,000 were recorded. For the three months ended June 30, 2015, an unrealized loss of approximately $1,000 and a realized loss of approximately $49,000 were recorded. For the six months ended June 30, 2015, an unrealized gain of approximately $9,000 and a realized loss of approximately $101,000 were recorded.

Restricted Stock Awards On May 17, 2016, we awarded approximately 28,000 shares of restricted stock to a director at a grant date price of $10.68. The restricted stock award vests over 4 years in 25% increments. Director’s compensation recognized during the three and six months ended June 30, 2016, was approximately $13,000. On March 1, 2016, we awarded approximately 135,000 shares of restricted stock to officers at a grant date price of $9.39. One-half of the restricted stock vests ratably over 3 years. The other half vests at the end of the three years based upon the performance metrics of return on invested capital and earnings per share growth. The number of shares actually granted will be adjusted based upon relative performance to our peers. Compensation expense recognized during the three and six months ended June 30, 2016, was approximately $106,000 and $141,000. On January 29, 2016, we awarded 35,333 shares of restricted stock to a director at a grant date price of $10.52. The restricted stock award vests over 5 years in 20% increments with the first tranche issued on January 29, 2016. Director’s compensation recognized during the three and six months ended June 30, 2016, was approximately $19,000 and $105,000. Directors’ compensation of approximately $3,000 and $6,000 during the three months and $21,000 and $6,000 during the six months ended June 30, 2016, and 2015, respectively, was recognized related to restricted stock grants vesting through 2020. Employee compensation of approximately $108,000 and $108,000 during the three months and $215,000 and $179,000 during the six months ended June 30, 2016, and 2015, respectively, was recognized related to restricted stock with a 4 year vesting period which was awarded to officers. This restricted stock vests through 2019. Employee compensation of approximately $0 and $181,000 during the three and six months ended June 30, 2015, for fully vested restricted stock which was awarded to various employees. Restricted stock activity in the first six months of 2016 was as follows: Shares of Restricted Stock Weighted Average Grant Date Price per Share Outstanding at January 1, 2016 148,040 $ 14.14 Granted 198,354 9.77 Vested (42,575 ) 13.60 Outstanding at June 30, 2016 303,819 $ 11.37 Stock Option and Warrant Awards A summary of the status of our stock option awards and warrants is presented below: Number of Stock Options & Warrants Weighted Average Exercise Price per Share Weighted Average Remaining Contractual Life Outstanding at January 1, 2016 1,376,437 $ 7.68 Granted -- -- Exercised (8,000 ) 2.84 Expired -- -- Cancelled -- -- Forfeited -- -- Outstanding at June 30, 2016 1,368,437 $ 7.71 5.6 Exercisable at June 30, 2016 835,937 $ 7.49 5.6 The fair value of the options granted were calculated using the Black Scholes option valuation model with the assumptions as disclosed in prior quarterly and annual filings. Directors’ compensation of approximately $47,000 and $53,000 during the three months and $114,000 and $128,000 during the six months ended June 30, 2016, and 2015, respectively, was recognized related to options to purchase shares vesting through 2017.

These options vest through 2018. Post-retirement compensation of approximately $24,000 and $49,000 was recognized during the three months and six months ended June 30, 2016, and 2015, related to options awarded to Mr. Hatem El Khalidi in July 2009. On May 9, 2010, the Board of Directors determined that Mr. El Khalidi forfeited these options and other retirement benefits when he made various demands against the Company and other AMAK Saudi shareholders which would benefit him personally and were not in the best interests of the Company and its shareholders. The Company is litigating its right to withdraw the options and benefits and as such, these options and benefits continue to be shown as outstanding. See further discussion in Note 19.

Tax returns for the years 2011 through 2014 remain open for examination in various tax jurisdictions in which we operate. As of June 30, 2016, and December 31, 2015, we recognized no material adjustments in connection with uncertain tax positions. The effective tax rate varies from the federal statutory rate of 35% primarily as a result of state tax expense and stock option based compensation offset by the manufacturing deduction.

INVESTMENT IN AMAK [Abstract]
INVESTMENT IN AMAK	17. INVESTMENT IN AMAK As of June 30, 2016, and December 31, 2015, the Company had a non-controlling equity interest (35%) in AMAK of approximately $52.0 million and $47.7 million, respectively. This investment is accounted for under the equity method. There were no events or changes in circumstances that may have an adverse effect on the fair value of our investment in AMAK at June 30, 2016. AMAK’s financial statements were prepared in the functional currency of AMAK which is the Saudi Riyal (SR). In June 1986 the SR was officially pegged to the U. S.

COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	19. COMMITMENTS AND CONTINGENCIES Guarantees On October 24, 2010, we executed a limited Guarantee in favor of the Saudi Industrial Development Fund (“SIDF”) whereby we agreed to guaranty up to 41% of the SIDF loan to AMAK in the principal amount of 330.0 million Saudi Riyals (US$88.0 million) (the “Loan”). The term of the loan is through June 2019. As a condition of the Loan, SIDF required all shareholders of AMAK to execute personal or corporate Guarantees; as a result, our guarantee is for approximately 135.33 million Saudi Riyals (US$36.1 million). The loan was necessary to continue construction of the AMAK facilities and provide working capital needs. We received no consideration in connection with extending the guarantee and did so to maintain and enhance the value of its investment. The total amount outstanding to the SIDF at June 30, 2016, was 310.0 million Saudi Riyals (US$82.7 million). Litigation On March 21, 2011, Mr. El Khalidi filed suit against the Company 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 defamation 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. 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. On or about March 18, 2016, SHR received notice of a lawsuit filed in the 172 nd Environmental Remediation Amounts charged to expense for various activities related to environmental monitoring, compliance, and improvements were approximately $154,000 and $192,000 for the three months and $301,000 and $329,000 for the six months ended June 30, 2016, and 2015, respectively.
