The computation of basic and diluted net income per common share is as follows:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,
	2017		2016		2017		2016

Credit Agreement

On December 9, 2008, the Company and its wholly owned subsidiary, Corecomposites de Mexico, S. de R.L. de C.V., entered into a credit agreement, as amended from time to time (the "Credit Agreement"), with a lender to provide various financing facilities.

Under the Credit Agreement, amended with the eleventh amendment on June 21, 2016, the Company received certain loans, subject to the terms and conditions stated in the agreement, which included (1) a $12,000,000 Capex loan; (2) an $18,000,000 variable rate revolving line of credit with a commitment date extending through May 31, 2018; (3) a term loan in an original amount of $15,500,000 (the "Term Loan"); and (4) a Letter of Credit Commitment of up to $250,000, of which $175,000 has been issued. The Credit Agreement is secured by a guarantee of each U.S. subsidiary of the Company, and by a lien on substantially all of the present and future assets of the Company and its U.S. subsidiaries, except that only 65% of the stock issued by Corecomposites de Mexico, S. de R.L. de C.V. has been pledged.

On August 4, 2017, the Company and its wholly owned subsidiary, Corecomposites de Mexico, S. de R.L. de C.V., entered into a twelfth amendment (the "Twelfth Amendment") to the Credit Agreement. Pursuant to the terms of the Twelfth Amendment, the parties agreed to modify certain terms of the Credit Agreement. These modifications included amending the definition of Consolidated Fixed Charges to include only Capital Distributions made in an aggregate amount in excess of Two Million Dollars ($2,000,000) and amending the restricted payment covenant provisions.

Bank Covenants

The Company is required to meet certain financial covenants included in the Credit Agreement with respect to leverage ratios, fixed charge ratios, capital expenditures as well as other customary affirmative and negative covenants. As of September 30, 2017, the Company was in compliance with its financial covenants associated with the loans made under the Credit Agreement as described above.

8. Income Taxes

The Company’s consolidated balance sheets include a net non-current deferred tax liability of $992,000 at September 30, 2017 and December 31, 2016. The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more likely than not to realize deferred tax benefits through the generation of future taxable income.

Income tax expense for the nine months ended September 30, 2017 is estimated to be $2,262,000, or approximately 32% of income before income taxes. Income tax expense for the nine months ended September 30, 2016 was estimated to be $2,794,000, or approximately 34% of income before income taxes.

As of September 30, 2017 and December 31, 2016, the Company had no liability for unrecognized tax benefits. The Company does not anticipate that unrecognized tax benefits will significantly change within the next twelve months.

The Company files income tax returns in the U.S., Mexico and various state jurisdictions. The Company is no longer subject to U.S. federal and state income tax examinations by tax authorities for years prior to 2013, and is no longer subject to Mexican income tax examinations by Mexican authorities for years prior to 2012.

9. Share Based Compensation

The Company has a Long Term Equity Incentive Plan, as approved by the Company’s stockholders in May 2006 and as amended in May 2015 (the “2006 Plan”). The 2006 Plan allows for grants to directors and employees of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, performance shares, performance units and other incentive awards (“Stock Awards”) up to an aggregate of 3,000,000 awards, each representing a right to buy a share of Core Molding Technologies common stock. Stock Awards can be granted under the 2006 Plan through the earlier of December 31, 2025, or the date the maximum number of available awards under the 2006 Plan have been granted.

Restricted Stock

The Company grants shares of its common stock to certain directors, officers, and key managers in the form of unvested stock (“Restricted Stock”). These awards are recorded at the market value of Core Molding Technologies’ common stock on the date of issuance, net of estimated forfeitures, and amortized ratably as compensation expense over the applicable vesting period, which is typically three years. The Company has applied forfeiture rates, estimated based on historical experience, of 3.5%-6.5% to the restricted stock fair values. These estimated forfeiture rates are applied to grants based on their remaining vesting term and may be revised in subsequent periods if actual forfeitures differ from these estimates.

The following summarizes the status of Restricted Stock and changes during the nine months ended September 30, 2017:

	Number of Shares		Weighted Average Grant Date Fair Value
Unvested balance at December 31, 2016	158,261		$	14.55
Granted	84,643		19.17
Vested	(95,717	)	15.12
Forfeited	(6,092	)	17.93
Unvested balance at September 30, 2017	141,095		$	16.84

At September 30, 2017 and 2016, there was $1,871,000 and $1,580,000, respectively, of total unrecognized compensation expense related to Restricted Stock granted under the 2006 Plan. That cost is expected to be recognized over the weighted-average period of 1.6 years. Total compensation cost related to restricted stock grants for the three months ended September 30, 2017 and 2016 was $270,000 and $197,000, respectively, all of which was recorded to selling, general and administrative expense. Compensation cost related to restricted stock grants for the nine months ended September 30, 2017 and 2016 was $1,061,000 and $778,000, respectively, all of which was recorded to selling, general and administrative expense.

The Company does not receive a tax deduction for restricted stock until the restricted stock vests. The tax deduction for restricted stock is based on the fair market value as of the vesting date. Tax benefits received for vested restricted stock in excess of the fair market value as of the grant date were $136,000 for the nine months ended September 30, 2017. Tax expense due for the fair market value as of the grant date in excess of the vested restricted stock was $16,000 for the nine months ended September 30, 2016.

During the nine months ended September 30, 2017 and 2016, employees surrendered 19,533 and 10,590 shares, respectively, of the Company's common stock to satisfy income tax withholding obligations in connection with the vesting of restricted stock.

10. Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in a transaction between market participants as of the measurement date. Fair value is measured using the fair value hierarchy and related valuation methodologies as defined in the authoritative literature. This guidance provides a fair value framework that requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment.

12

The three levels are defined as follows:

Level 1 - Quoted prices in active markets for identical assets and liabilities.

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets.

Level 3 - Significant unobservable inputs reflecting management's own assumptions about the inputs used in pricing the asset or liability.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, debt and foreign currency derivatives. Cash and cash equivalents, accounts receivable and accounts payable carrying values as of September 30, 2017 and December 31, 2016 approximate fair value due to the short-term maturities of these financial instruments. The carrying amounts of long-term debt and the revolving line of credit approximate fair value as of September 30, 2017 and December 31, 2016 due to the short term nature of the underlying variable rate LIBOR agreements. The Company had Level 2 fair value measurements at September 30, 2017 and December 31, 2016 relating to the Company’s foreign currency derivatives.

Derivative and hedging activities

The Company conducts business in Mexico and pays certain expenses in Mexican Pesos. The Company is exposed to foreign currency exchange risk between the U.S. dollar and the Mexican Peso, which could impact the Company’s operating income and cash flows. To mitigate risk associated with foreign currency exchange, the Company enters into forward contracts to exchange a fixed amount of U.S. dollars for a fixed amount of Mexican Pesos, which will be used to fund future Peso cash flows. At inception, all forward contracts are formally documented as cash flow hedges and are measured at fair value each reporting period. Derivatives are formally assessed both at inception and at least quarterly thereafter, to ensure that derivatives used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged item. If it is determined that a derivative ceases to be a highly effective hedge, or if the anticipated transaction is no longer probable of occurring, hedge accounting is discontinued, and any future mark-to-market adjustments are recognized in earnings. The effective portion of gain or loss is reported in other comprehensive income and the ineffective portion is reported in earnings. The impacts of these contracts were largely offset by gains and losses resulting from the impact of changes in exchange rates on transactions denominated in the Mexican Peso. As of September 30, 2017, the Company had no ineffective portion related to the cash flow hedges.

The effect of post-retirement benefit items reclassified from Accumulated Other Comprehensive Income is included in total cost of sales on the Consolidated Statements of Income. These Accumulated Other Comprehensive Income components are included in the computation of net periodic benefit cost (see Note 6 "Post Retirement Benefits" for additional details). The tax effect of post-retirement benefit items reclassified from Accumulated Other Comprehensive Income is included in income tax expense on the Consolidated Statements of Income.

12. Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. ASC Topic 606 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASC Topic 606 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The effective date for ASC Topic 606, as updated by ASU No. 2015-14 in August 2015, has been delayed until the first quarter of fiscal year 2018. ASU 2014-09 will affect the timing of certain revenue related transactions primarily resulting from the earlier recognition of the Company's tooling sales and costs. Upon adoption of ASU 2014-09 tooling sales and costs will be recorded over time on a percentage of completion methodology instead of completed contract methodology. We are nearing a decision on implementation on a retrospective basis (full or with practical expedient) or through a cumulative adjustment to equity. We continue to assess the overall impact the adoption of ASU 2014-09 will have on our consolidated financial statements, and anticipate testing our new controls and processes designed to comply with ASU 2014-09 throughout 2017 to permit adoption by January 1, 2018.

15

In January 2017, FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new standard eliminates step 2, which required companies to determine the implied fair value of the reporting unit's goodwill, of the goodwill impairment test. Under this new guidance, companies will perform their annual goodwill impairment test by comparing the reporting unit's carrying value, including goodwill, to the fair value. An impairment charge would be recorded if the carrying value exceeds the reporting unit's fair value. The ASU is effective for public companies for annual periods, and interim periods within those annual periods, beginning after December 15, 2020 and early adoption is permitted. The Company will adopt this standard update as required and does not expect the adoption of this ASU to have a material impact on our consolidated financial statements.

In March 2017, FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). The amendments in this update require that an employer disaggregate the service cost component from the other components of net periodic cost (benefit) and report that component in the same line item as other compensation costs arising from services rendered by employees during the period. The other components of net periodic cost (benefit) are required to be presented in the statement of operations separately from the service cost component and outside of operating earnings. The amendment also allows for the service cost component of net periodic cost (benefit) to be eligible for capitalization when applicable. The guidance will be effective for the Company on January 1, 2018 and interim periods within that reporting period; early adoption permitted. The guidance on the income statement presentation of the components of net periodic cost (benefit) must be applied retrospectively, while the guidance limiting the capitalization of net periodic cost (benefit) in assets to the service cost component must be applied prospectively. The Company will adopt this standard update as required and does not expect the adoption of this ASU to have a material impact on our consolidated financial statements. Upon adoption, the Company plans to update the presentation of net periodic cost (benefit) accordingly, noting all components of the Company's net periodic cost (benefit) will be presented outside of operating earnings, as the plan is not active.The estimated impact of adoption of this update will be a reclassification of all components of net periodic benefit from operating earnings to other income in the amount of $49,000 and $18,000 for the years ended December 31, 2017 and December 31, 2016, respectively.

In August 2017, FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new standard provides changes to designation, measurement, recognition and presentation of hedging instruments. The ASU is effective for public companies for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 and early adoption is permitted. The Company will adopt this standard update as required and does not expect the adoption of this ASU to have a material impact on our consolidated financial statements.

Except as required by law, Core Molding Technologies, Inc. undertakes no obligation to update these forward looking statements.

Core Molding Technologies believes that the following factors, among others, could affect its future performance and cause actual results to differ materially from those expressed or implied by forward-looking statements made in this report: business conditions in the plastics, transportation, marine and commercial product industries (including slowdown in demand for truck production); federal and state regulations (including engine emission regulations); general economic, social, regulatory (including foreign trade policy) and political environments in the countries in which Core Molding Technologies operates; safety and security conditions in Mexico; dependence upon certain major customers as the primary source of Core Molding Technologies’ sales revenues; efforts of Core Molding Technologies to expand its customer base; the ability to develop new and innovative products and to diversify markets, materials and processes and increase operational enhancements; the actions of competitors, customers, and suppliers; failure of Core Molding Technologies’ suppliers to perform their obligations; the availability of raw materials; inflationary pressures; new technologies; regulatory matters; labor relations; the loss or inability of Core Molding Technologies to attract and retain key personnel; the Company's ability to successfully identify, evaluate and manage potential acquisitions and to benefit from and properly integrate any completed acquisitions; federal, state and local environmental laws and regulations; the availability of capital; the ability of Core Molding Technologies to provide on-time delivery to customers, which may require additional shipping expenses to ensure on-time delivery or otherwise result in late fees; risk of cancellation or rescheduling of orders; management’s decision to pursue new products or businesses which involve additional costs, risks or capital expenditures; inadequate insurance coverage to protect against potential hazards; equipment and machinery failure; product liability and warranty claims; and other risks identified from time to time in Core Molding Technologies’ other public documents on file with the Securities and Exchange Commission, including those described in Item 1A of the 2016 Annual Report on Form 10-K.

Description of the Company

Core Molding Technologies is a manufacturer of sheet molding compound ("SMC") and molder of fiberglass reinforced plastics. The Company specializes in large-format moldings and offers a wide range of fiberglass processes, including compression molding of SMC, glass mat thermoplastics, bulk molding compounds and direct long-fiber thermoplastics (D-LFT); spray-up, hand-lay-up, and resin transfer molding ("RTM"). Additionally, the Company offers reaction injection molding, utilizing dicyclopentadiene technology. Core Molding Technologies serves a wide variety of markets, including medium and heavy-duty truck, marine, automotive, agriculture, construction and other commercial products. Product sales to heavy and medium-duty truck markets accounted for 68% and 69% of the Company’s sales for the nine months ended September 30, 2017 and 2016, respectively. The demand for Core Molding Technologies’ products is primarily affected by economic conditions in the United States, Canada, and Mexico. Core Molding Technologies’ manufacturing operations have a significant fixed cost component. Accordingly, during periods of changing demand, the profitability of Core Molding Technologies’ operations may change proportionately more than revenues from operations.

In 1996, Core Molding Technologies acquired substantially all of the assets and assumed certain liabilities of Columbus Plastics, a wholly owned operating unit of Navistar’s truck manufacturing division since its formation in late 1980. Columbus Plastics, located in Columbus, Ohio, was a compounder and compression molder of SMC. In 1998, Core Molding Technologies began operations at its second facility in Gaffney, South Carolina, and in 2001, the Company established a manufacturing presence in Mexico by acquiring certain assets of Airshield Corporation. As a result of this acquisition, Core Molding Technologies expanded its fiberglass molding capabilities to include the spray up, hand-lay-up open mold processes and RTM closed molding. In 2004, the Company acquired substantially all the operating assets of Keystone Restyling Products, Inc., a privately held manufacturer and distributor of fiberglass reinforced products for the automotive-aftermarket industry. In 2005, Core Molding Technologies acquired certain assets of the Cincinnati Fiberglass Division of Diversified Glass, Inc., a Batavia, Ohio-based, privately held manufacturer and distributor of fiberglass reinforced plastic components supplied primarily to the heavy-duty truck market. In

2009, the Company completed construction of a production facility in Matamoros, Mexico that replaced its leased facility. Most recently in 2015, the Company acquired substantially all of the assets of CPI Binani, Inc. ("CPI"), a wholly-owned subsidiary of Binani Industries Limited, located in Winona, Minnesota, which expanded the Company's process capabilities to include D-LFT and diversified its customer base.

Overview

For the nine months ended September 30, 2017, the Company recorded net income of $4,704,000, or $0.61 per basic and diluted share, compared with net income of $5,379,000, or $0.71 per basic and $0.70 per diluted share for the nine months ended September 30, 2016. Product sales for the nine months ended September 30, 2017 decreased approximately 2% to $110,723,000 as compared to $113,159,000 for the same period in 2016, primarily due to decreased demand from heavy duty truck and automotive customers, partially offset by increased demand from customers in the marine market.

Looking forward, the Company expects the fourth quarter 2017 product sales to be higher than fourth quarter 2016 and full year 2017 product revenue to be flat compared to full year 2016.  Current industry analyst forecasts for North American Class 8 truck production show a 15% increase in 2018 compared to 2017.  Based on industry analyst expectations and customer forecasts, the Company expects 2018 total product revenues to be higher than 2017. 

Results of Operations

Three Months Ended September 30, 2017, as Compared to Three Months Ended September 30, 2016

Net sales for the three months ended September 30, 2017 and 2016 totaled $38,494,000 and $41,336,000, respectively. Included in total sales were tooling project sales of $901,000 and $7,520,000 for the three months ended September 30, 2017 and 2016, respectively. Tooling project sales result primarily from customer approval and acceptance of molds and assembly equipment specific to their products as well as other non-production services. These sales are sporadic in nature and fluctuate in regard to scope and related revenue on a period-to-period basis. Product sales, excluding tooling project sales, were 11%higher for the three months ended September 30, 2017, as compared to the same period a year ago. This increase in sales is primarily the result of higher demand from customers in both the heavy duty truck and marine markets, partially offset by a decrease in demand from customers in the automotive market.

Sales to Navistar totaled $11,331,000 for the three months ended September 30, 2017, compared to $10,045,000 for the three months ended September 30, 2016.

ended September 30, 2017 as compared to the same period of the prior year, due primarily to a change in demand from customers in the automotive market.

Gross margin was approximately 15.0% of sales for the three months ended September 30, 2017, compared with 13.5% for the three months ended September 30, 2016. The gross margin increase, as a percent of sales, was due to a favorable net change in production costs and product mix of 4.1% and favorable foreign exchange rate effect of 0.1%, partially offset by unfavorable net changes in selling price and material costs of 1.5% and lower fixed cost leverage of 1.2% related to the decrease in sales.

Selling, general and administrative expense (“SG&A”) was $4,358,000 for the three months ended September 30, 2017, compared to $3,924,000 for the three months ended September 30, 2016. The increase in SG&A expense primarily resulted from higher professional and outside service expenses of $321,000.

Interest expense totaled $62,000 for the three months ended September 30, 2017, compared to interest expense of $67,000 for the three months ended September 30, 2016. The decrease in interest expense was primarily due to a lower average outstanding debt balance during the three months ended September 30, 2017, when compared to the same period in 2016.

Income tax expense for the three months ended September 30, 2017 and 2016 was approximately 36% and 35% of total income before income taxes. The Company recorded net income for the three months ended September 30, 2017 of $855,000, or $0.11 per basic and diluted share, compared with net income of $1,029,000, or $0.13 per basic and diluted share, for the three months ended September 30, 2016.

Comprehensive income totaled $703,000 for the three months ended September 30, 2017, compared to $1,013,000 for the same period in 2016. This decrease was primarily made up of a $174,000 decrease in net income.

Nine Months Ended September 30, 2017, as Compared to Nine Months Ended September 30, 2016

Net sales for the nine months ended September 30, 2017 and 2016 totaled $122,608,000 and $125,810,000, respectively. Included in total sales were tooling project sales of $11,885,000 and $12,651,000 for the nine months ended September 30, 2017 and 2016, respectively. Tooling project sales result primarily from customer approval and acceptance of molds and assembly equipment specific to their products as well as other non-production services. These sales are sporadic in nature and fluctuate in regard to scope and related revenue on a period-to-period basis. Product sales, excluding tooling project sales, were approximately 2%lower for the nine months ended September 30, 2017, as compared to the same period a year ago. This decrease in sales is primarily the result of lower net demand from customers in the heavy truck and automotive markets, partially offset by increased demand from customers in the marine market.

Sales to Navistar totaled $30,585,000 for the nine months ended September 30, 2017, compared to $32,470,000 for the nine months ended September 30, 2016. Included in total sales was $90,000 of tooling sales for the nine months ended September 30, 2017 compared to $1,166,000 for the same nine months in 2016. Product sales decreased3% for the nine months ended September 30, 2017 as compared to the same period in the prior year, due to a change in demand, partially offset by new business awards.

Sales to Volvo totaled $28,055,000 for the nine months ended September 30, 2017, compared to $29,266,000 for the nine months ended September 30, 2016. Included in total sales was $8,011,000 of tooling sales for the nine months ended September 30, 2017 compared to $5,801,000 for the same nine months in 2016. Product sales to Volvo decreased15% for the nine months ended September 30, 2017 as compared to the same period in the prior year, due to a change in demand.

Sales to PACCAR totaled $22,100,000 for the nine months ended September 30, 2017, compared to $21,888,000 for the nine months ended September 30, 2016. Included in total sales was $2,932,000 of tooling sales for the nine months ended September 30, 2017 compared to $3,454,000 for the same nine months in 2016. Product sales to PACCAR increased4% for the nine months ended September 30, 2017 as compared to the same period in the prior year, due to new business awards, partially offset by a change in demand.

Sales to Yamaha totaled $11,847,000 for the nine months ended September 30, 2017, compared to $11,658,000 for the nine months ended September 30, 2016. Product sales to Yamaha increased2% for the nine months ended September 30, 2017 as compared to the same period in the prior year, due to a change in demand.

Sales to BRP totaled $10,967,000 for the nine months ended September 30, 2017, compared to $9,427,000 for the nine months ended September 30, 2016. Included in total sales was $514,000 of tooling sales for the nine months ended September 30, 2017 compared to $1,624,000 for the same nine months in 2016. Product sales to BRP increased34% for the nine months ended September 30, 2017 as compared to the same period in the prior year, due to new business awards and a change in demand.

18

Sales to other customers for the nine months ended September 30, 2017 totaled $19,054,000, compared to $21,101,000 for the nine months ended September 30, 2016. Included in total sales was $338,000 of tooling sales for the nine months ended September 30, 2017 compared to $606,000 for the same nine months in 2016. Product sales to other customers decreased9% for the nine months ended September 30, 2017 as compared to the same period in the prior year. The decrease primarily relates to a change in demand from customers in the automotive market.

Gross margin was approximately 16.0% of sales for the nine months ended September 30, 2017, compared with 16.5% for the nine months ended September 30, 2016. The gross margin decline, as a percent of sales, was due to unfavorable net changes in selling price and material costs of 1.1% and lower fixed cost leverage of 0.2% related to a decrease in sales, partially offset by a favorable foreign exchange rate effect of 0.5% and a favorable net change in production costs and product mix of 0.3%.

Selling, general and administrative expense (“SG&A”) was $12,450,000 for the nine months ended September 30, 2017, compared to $12,361,000 for the nine months ended September 30, 2016. The increase in SG&A expense primarily resulted from higher labor and benefit expenses of $466,000 and higher professional and outside services of $148,000, partially offset by lower profit sharing expense of $461,000.

Interest expense totaled $191,000 for the nine months ended September 30, 2017, compared to interest expense of $233,000 for the nine months ended September 30, 2016. The decrease in interest expense was primarily due to a lower average outstanding debt balance in 2016.

Income tax expense for the nine months ended September 30, 2017 and 2016 was approximately 32% and 34% of total income before income taxes. During the nine months ended September 30, 2017 the Company received a tax benefit of $136,000 due to the fair market value of the vested restricted stock being in excess of the fair market value as of the grant date.

The Company recorded net income for the nine months ended September 30, 2017 of $4,704,000, or $0.61 per basic and diluted share, compared with net income of $5,379,000, or $0.71 per basic and $0.70 per diluted share, for the nine months ended September 30, 2016.

Comprehensive income totaled $4,956,000 for the nine months ended September 30, 2017, compared to $5,247,000 over the same period in 2016. The decrease resulted from a $675,000 decrease in net income, partially offset by a net gain related to net unrealized foreign currency hedges of $434,000.

Liquidity and Capital Resources

The Company’s primary sources of funds have been cash generated from operating activities and borrowings from third parties. Primary cash requirements are for operating expenses, increases in working capital, capital expenditures, repayment of long-term debt, dividend payments and business acquisitions. The Company from time to time will enter into foreign exchange contracts to mitigate risk of foreign exchange movements. As of September 30, 2017, the Company had outstanding foreign exchange contracts with notional amounts totaling $5,038,000, compared to $6,502,000 outstanding as of December 31, 2016.

Cash provided by operating activities for the nine months ended September 30, 2017 totaled $4,529,000. Net income of $4,704,000 positively impacted operating cash flows. Non-cash deductions of depreciation and amortization included in net income amounted to $4,814,000. Changes in working capital decreased cash provided by operating activities by $5,790,000, which primarily related to increases in accounts receivable, inventory, and prepaid and other assets, partially offset by an increase in accounts payable.

Cash used in investing activities for the nine months ended September 30, 2017 was $2,259,000, which relates to purchases of property, plant and equipment. The Company anticipates spending up to $3,000,000 during the remainder of 2017 on property, plant and equipment purchases for all of the Company's operations. At September 30, 2017, purchase commitments for capital expenditures in progress were $880,000. The Company anticipates using cash from operations to finance this capital investment.

Cash used in financing activities for the nine months ended September 30, 2017 totaled $3,015,000, which primarily consisted of scheduled repayments of principal on the Company's outstanding Term Loan of $2,250,000 and dividend payments of $393,000.

At September 30, 2017, the Company had $27,540,000 in cash on hand, and an available balance on the revolving line of credit of $18,000,000.

19

The Company is required to meet certain financial covenants included in the Credit Agreement with respect to leverage ratios, fixed charge ratios, capital expenditures as well as other customary affirmative and negative covenants. As of September 30, 2017, the Company was in compliance with its financial covenants.

Management regularly evaluates the Company’s ability to effectively meet its debt covenants. Based on the Company’s forecasts, which are based on industry analysts’ estimates of heavy and medium-duty truck production volumes, as well as other assumptions, management believes that the Company will be able to maintain compliance with its financial covenants for the next 12 months. Management believes that cash flow from operating activities and available borrowings under the Credit Agreement will be sufficient to meet the Company’s liquidity needs for the next 12 months. If a material adverse change in the financial position of Core Molding Technologies should occur, or if actual sales or expenses are substantially different than what has been forecasted, Core Molding Technologies’ liquidity and ability to obtain further financing to fund future operating and capital requirements could be negatively impacted.

Recent Accounting Pronouncements

For information on the impact of recently issued accounting pronouncements, see Note 12 "Recent Accounting Pronouncements," to the consolidated financial statements included herein.

Off-Balance Sheet Arrangements

The Company did not have any off-balance sheet arrangements as of September 30, 2017 or December 31, 2016.

The Company did not have or experience any  material changes outside the ordinary course of business as to contractual obligations, including long-term debt obligations, capital lease obligations, operating lease obligations, purchase obligations or other long-term liabilities reflected on the Company’s balance sheet under GAAP, as of September 30, 2017 or December 31, 2016.

Critical Accounting Policies and Estimates

Management’s Discussion and Analysis of Financial Condition and Results of Operations discuss the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the 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 period. On an on-going basis, management evaluates its estimates and judgments. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Management believes the following critical accounting policies, among others, affect its more significant judgments and estimates used in the preparation of its consolidated financial statements.

Accounts receivable allowances: Management maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of the Company’s customers was to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company has determined that no allowance for doubtful accounts was needed at September 30, 2017 and at December 31, 2016, respectively. Management also records estimates for chargebacks for customer returns and deductions, discounts offered to customers, and price adjustments. Should customer chargebacks fluctuate from the estimated amounts, additional allowances may be required. The Company reduced accounts receivable for chargebacks by $390,000 at September 30, 2017 and $309,000 at December 31, 2016.

Inventories: Inventories, which include material, labor and manufacturing overhead, are valued at the lower of cost or market. The inventories are accounted for using the first-in, first-out (FIFO) method of determining inventory costs. Inventory quantities on-hand are regularly reviewed, and where necessary, provisions for excess and obsolete inventory are recorded based on historical and anticipated usage. The Company has recorded an allowance for slow moving and obsolete inventory of $629,000 at September 30, 2017 and $770,000 at December 31, 2016.

Derivative instruments: Derivative instruments are utilized to manage exposure to fluctuations in the United States dollar to Mexican peso exchange rate. All derivative instruments are formally documented as cash flow hedges and are recorded at fair value at each reporting period. Gains and losses related to currency forward contracts are deferred and recorded as a component of Accumulated Other Comprehensive Income in the Consolidated Statement of Stockholders' Equity and then subsequently r

20

ecognized in the Consolidated Statement of Income when the hedged item affects net income. Any ineffective portion of the change in fair value of a hedge is recognized in income immediately. For additional information on derivative instruments, see Note 10.

Long-Lived Assets: Long-lived assets consist primarily of property, plant and equipment and definite-lived intangibles. The recoverability of long-lived assets is evaluated by an analysis of operating results and consideration of other significant events or changes in the business environment. The Company evaluates whether impairment exists for property, plant and equipment on the basis of undiscounted expected future cash flows from operations before interest. There was no impairment of the Company's long-lived assets for the nine months ended September 30, 2017 or September 30, 2016.

Goodwill and Other Intangibles: The Company has recorded $2,403,000 of goodwill as a result of two acquisitions. In 2001, the Company acquired certain assets of Airshield Corporation, and as a result, recorded goodwill in the amount of $1,097,000. The Company also acquired substantially all of the assets of CPI on March 20, 2015, which resulted in approximately $1,306,000 of goodwill.

The Company evaluates goodwill annually on December 31st to determine whether impairment exists, or at interim periods if an indicator of possible impairment exists. The Company evaluates goodwill for impairment utilizing the one-step qualitative assessment. The Company considers relevant events and circumstances that affect the fair value or carrying amount of the Company. Such events and circumstances could include macroeconomic conditions, industry and market conditions, cost factors, overall financial performance, entity specific events and capital markets pricing. The Company places more weight on the events and circumstances that most affect the Company's fair value or carrying amount. These factors are all considered by management in reaching its conclusion about whether to perform the first step of the impairment test.

If the Company's fair value is determined to be more likely than not impaired based on the one-step qualitative approach, a quantitative valuation to estimate the fair value of the Company is performed. Fair value measurements are based on a projected discounted cash flow valuation model, in accordance with ASC 350, “Intangibles-Goodwill and Other.”

There was no impairment of the Company's goodwill for the year ended December 31, 2016, and no indicators of impairment for the nine months ended September 30, 2017.

Self-Insurance: The Company is self-insured with respect to its medical, dental and vision claims for all employees except employees working in Mexico. The Company is also self-insured with respect to its Columbus and Batavia, Ohio workers’ compensation claims, all of which are subject to stop-loss insurance thresholds. The Company has recorded an estimated liability for self-insured medical and dental claims incurred but not reported and worker’s compensation claims incurred but not reported at September 30, 2017 and December 31, 2016 of $1,208,000 and $1,139,000, respectively.

Post-retirement benefits: Management records an accrual for post-retirement costs associated with the health care plan sponsored by Core Molding Technologies. Should actual results differ from the assumptions used to determine the reserves, additional provisions may be required. In particular, increases in future healthcare costs above the assumptions could have an adverse effect on Core Molding Technologies’ operations. The effect of a change in healthcare costs is described in Note 12 of the Notes to Consolidated Financial Statements contained in the Company's 2016 Annual Report to Shareholders on Form 10-K. Core Molding Technologies had a liability for post retirement healthcare benefits based on actuarially computed estimates of $8,638,000 at September 30, 2017 and $8,667,000 at December 31, 2016.

Revenue Recognition: Revenue from product sales is recognized at the time products are shipped and title transfers. Allowances for returned products and other credits are estimated and recorded as revenue is recognized. Tooling revenue is recognized when the customer approves the tool and accepts ownership. Progress billings and expenses are shown net as an asset or liability on the Company’s Consolidated Balance Sheet. Tooling in progress can fluctuate significantly from period to period and is dependent upon the stage of tooling projects and the related billing and expense payment timetable for individual projects and therefore does not necessarily reflect projected income or loss from tooling projects. At September 30, 2017, the Company had a net liability related to tooling in progress of $1,184,000, which represented approximately $7,338,000 of progress tooling billings and $7,015,000 of progress tooling expenses. At December 31, 2016, the Company had a net liability related to tooling in progress of $1,084,000, which represented approximately $11,052,000 of progress tooling billings and $9,968,000 of progress tooling expenses.

Income taxes: The Company’s consolidated balance sheets include a net non-current deferred tax liability of $992,000 at September 30, 2017 and December 31, 2016. The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more likely than not to realize deferred tax benefits through the generation of future taxable

21

income. For more information, refer to Note 11 of the Notes to Consolidated Financial Statements contained in the Company's 2016 Annual Report to Shareholders on Form 10-K.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Core Molding Technologies’ primary market risk results from changes in the price of commodities used in its manufacturing operations. Core Molding Technologies is also exposed to fluctuations in interest rates and foreign currency fluctuations associated with the Mexican Peso. Core Molding Technologies does not hold any material market risk sensitive instruments for trading purposes. The Company may use derivative financial instruments to hedge exposure to fluctuations in foreign exchange rates and interest rates.

Core Molding Technologies has the following three items that are sensitive to market risks: (1) Revolving Line of Credit and Term Loan under the Credit Agreement, which bears a variable interest rate; (2) foreign currency purchases in which the Company purchases Mexican pesos with United States dollars to meet certain obligations that arise due to operations at the facility located in Mexico; and (3) raw material purchases in which Core Molding Technologies purchases various resins and fiberglass for use in production. The prices and availability of these materials are affected by the prices of crude oil and natural gas as well as processing capacity versus demand.

Assuming a hypothetical 10% increase in commodity prices, Core Molding Technologies would be impacted by an increase in raw material costs, which would have an adverse effect on operating margins.

Assuming a hypothetical 10% decrease in the United States dollar to Mexican Peso exchange rate, the Company would be impacted by an increase in operating costs, which would have an adverse effect on operating margins.

Assuming a hypothetical 10% change in short-term interest rates, interest paid on the Term Loan would have been impacted, as the interest rate on these loans is based upon LIBOR. It would not, however, have a material effect on earnings before tax.

Item 4. Controls and Procedures

As of the end of the period covered by this report, the Company has carried out an evaluation, under the supervision and with the participation of its management, including its Chief Executive Officer and its Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act). Based upon this evaluation, the Company’s management, including its Chief Executive Officer and its Chief Financial Officer, concluded that the Company’s disclosure controls and procedures were (i) effective to ensure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act was accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure, and (ii) effective to ensure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms.

There were no changes in internal control over financial reporting (as such term is defined in Exchange Act Rule 13a-15(f)) that occurred in the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Share-based Compensation [Abstract]

Stock Based Compensation

Share Based Compensation

The Company has a Long Term Equity Incentive Plan, as approved by the Company’s stockholders in May 2006 and as amended in May 2015 (the “2006 Plan”). The 2006 Plan allows for grants to directors and employees of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, performance shares, performance units and other incentive awards (“Stock Awards”) up to an aggregate of 3,000,000 awards, each representing a right to buy a share of Core Molding Technologies common stock. Stock Awards can be granted under the 2006 Plan through the earlier of December 31, 2025, or the date the maximum number of available awards under the 2006 Plan have been granted.

Restricted Stock

The Company grants shares of its common stock to certain directors, officers, and key managers in the form of unvested stock (“Restricted Stock”). These awards are recorded at the market value of Core Molding Technologies’ common stock on the date of issuance, net of estimated forfeitures, and amortized ratably as compensation expense over the applicable vesting period, which is typically three years. The Company has applied forfeiture rates, estimated based on historical experience, of 3.5%-6.5% to the restricted stock fair values. These estimated forfeiture rates are applied to grants based on their remaining vesting term and may be revised in subsequent periods if actual forfeitures differ from these estimates.

The following summarizes the status of Restricted Stock and changes during the nine months ended September 30, 2017:

	Number of Shares		Weighted Average Grant Date Fair Value
Unvested balance at December 31, 2016	158,261		$	14.55
Granted	84,643		19.17
Vested	(95,717	)	15.12
Forfeited	(6,092	)	17.93
Unvested balance at September 30, 2017	141,095		$	16.84

At September 30, 2017 and 2016, there was $1,871,000 and $1,580,000, respectively, of total unrecognized compensation expense related to Restricted Stock granted under the 2006 Plan. That cost is expected to be recognized over the weighted-average period of 1.6 years. Total compensation cost related to restricted stock grants for the three months ended September 30, 2017 and 2016 was $270,000 and $197,000, respectively, all of which was recorded to selling, general and administrative expense. Compensation cost related to restricted stock grants for the nine months ended September 30, 2017 and 2016 was $1,061,000 and $778,000, respectively, all of which was recorded to selling, general and administrative expense.

The Company does not receive a tax deduction for restricted stock until the restricted stock vests. The tax deduction for restricted stock is based on the fair market value as of the vesting date. Tax benefits received for vested restricted stock in excess of the fair market value as of the grant date were $136,000 for the nine months ended September 30, 2017. Tax expense due for the fair market value as of the grant date in excess of the vested restricted stock was $16,000 for the nine months ended September 30, 2016.

During the nine months ended September 30, 2017 and 2016, employees surrendered 19,533 and 10,590 shares, respectively, of the Company's common stock to satisfy income tax withholding obligations in connection with the vesting of restricted stock.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in a transaction between market participants as of the measurement date. Fair value is measured using the fair value hierarchy and related valuation methodologies as defined in the authoritative literature. This guidance provides a fair value framework that requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment.

The three levels are defined as follows:

Level 1 - Quoted prices in active markets for identical assets and liabilities.

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets.

Level 3 - Significant unobservable inputs reflecting management's own assumptions about the inputs used in pricing the asset or liability.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, debt and foreign currency derivatives. Cash and cash equivalents, accounts receivable and accounts payable carrying values as of September 30, 2017 and December 31, 2016 approximate fair value due to the short-term maturities of these financial instruments. The carrying amounts of long-term debt and the revolving line of credit approximate fair value as of September 30, 2017 and December 31, 2016 due to the short term nature of the underlying variable rate LIBOR agreements. The Company had Level 2 fair value measurements at September 30, 2017 and December 31, 2016 relating to the Company’s foreign currency derivatives.

Derivative and hedging activities

The Company conducts business in Mexico and pays certain expenses in Mexican Pesos. The Company is exposed to foreign currency exchange risk between the U.S. dollar and the Mexican Peso, which could impact the Company’s operating income and cash flows. To mitigate risk associated with foreign currency exchange, the Company enters into forward contracts to exchange a fixed amount of U.S. dollars for a fixed amount of Mexican Pesos, which will be used to fund future Peso cash flows. At inception, all forward contracts are formally documented as cash flow hedges and are measured at fair value each reporting period. Derivatives are formally assessed both at inception and at least quarterly thereafter, to ensure that derivatives used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged item. If it is determined that a derivative ceases to be a highly effective hedge, or if the anticipated transaction is no longer probable of occurring, hedge accounting is discontinued, and any future mark-to-market adjustments are recognized in earnings. The effective portion of gain or loss is reported in other comprehensive income and the ineffective portion is reported in earnings. The impacts of these contracts were largely offset by gains and losses resulting from the impact of changes in exchange rates on transactions denominated in the Mexican Peso. As of September 30, 2017, the Company had no ineffective portion related to the cash flow hedges.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. ASC Topic 606 is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASC Topic 606 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The effective date for ASC Topic 606, as updated by ASU No. 2015-14 in August 2015, has been delayed until the first quarter of fiscal year 2018. ASU 2014-09 will affect the timing of certain revenue related transactions primarily resulting from the earlier recognition of the Company's tooling sales and costs. Upon adoption of ASU 2014-09 tooling sales and costs will be recorded over time on a percentage of completion methodology instead of completed contract methodology. We are nearing a decision on implementation on a retrospective basis (full or with practical expedient) or through a cumulative adjustment to equity. We continue to assess the overall impact the adoption of ASU 2014-09 will have on our consolidated financial statements, and anticipate testing our new controls and processes designed to comply with ASU 2014-09 throughout 2017 to permit adoption by January 1, 2018.

In January 2017, FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new standard eliminates step 2, which required companies to determine the implied fair value of the reporting unit's goodwill, of the goodwill impairment test. Under this new guidance, companies will perform their annual goodwill impairment test by comparing the reporting unit's carrying value, including goodwill, to the fair value. An impairment charge would be recorded if the carrying value exceeds the reporting unit's fair value. The ASU is effective for public companies for annual periods, and interim periods within those annual periods, beginning after December 15, 2020 and early adoption is permitted. The Company will adopt this standard update as required and does not expect the adoption of this ASU to have a material impact on our consolidated financial statements.

In March 2017, FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost ("ASU 2017-07"). The amendments in this update require that an employer disaggregate the service cost component from the other components of net periodic cost (benefit) and report that component in the same line item as other compensation costs arising from services rendered by employees during the period. The other components of net periodic cost (benefit) are required to be presented in the statement of operations separately from the service cost component and outside of operating earnings. The amendment also allows for the service cost component of net periodic cost (benefit) to be eligible for capitalization when applicable. The guidance will be effective for the Company on January 1, 2018 and interim periods within that reporting period; early adoption permitted. The guidance on the income statement presentation of the components of net periodic cost (benefit) must be applied retrospectively, while the guidance limiting the capitalization of net periodic cost (benefit) in assets to the service cost component must be applied prospectively. The Company will adopt this standard update as required and does not expect the adoption of this ASU to have a material impact on our consolidated financial statements. Upon adoption, the Company plans to update the presentation of net periodic cost (benefit) accordingly, noting all components of the Company's net periodic cost (benefit) will be presented outside of operating earnings, as the plan is not active.The estimated impact of adoption of this update will be a reclassification of all components of net periodic benefit from operating earnings to other income in the amount of $49,000 and $18,000 for the years ended December 31, 2017 and December 31, 2016, respectively.

In August 2017, FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new standard provides changes to designation, measurement, recognition and presentation of hedging instruments. The ASU is effective for public companies for annual periods, and interim periods within those annual periods, beginning after December 15, 2018 and early adoption is permitted. The Company will adopt this standard update as required and does not expect the adoption of this ASU to have a material impact on our consolidated financial statements.
