FOR THE THRITY-NINETHIRTEEN WEEKS ENDED SEPTEMBER 24,APRIL 1, 2017 AND MARCH 26, 2016 AND SEPTEMBER 26, 2015

(UNAUDITED)

As used herein, unless the context otherwise requires, “Dorman”, the “Company”, “we”, “us”, or “our” refers to Dorman Products, Inc. and its subsidiaries. Our ticker symbol on the NASDAQ Global Select Market is “DORM”.

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. for interim financial information and in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). However, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of only normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the thirty-ninethirteen weeks ended September 24, 2016April 1, 2017 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2016.30, 2017. We may experience significant fluctuations from quarter to quarter in our results of operations due to the timing of orders placed by our customers. Generally, the second and third quarters have the highest level of net sales. The introduction of new products and product lines to customers may cause significant fluctuations from quarter to quarter. These financial statements should be read in conjunction with the consolidated financial statements and footnotes thereto included in our Annual Report on Form10-K for the fiscal year ended December 26, 2015.31, 2016.

On January 6, 2017, we acquired certain assets of Ingalls Engineering Company, Inc., a chassis and suspension business, primarily to expand our product portfolio. The purchase price was approximately $4.8 million, comprised of $3.1 million of cash and $1.7 million of estimated contingent payments. The contingent payment arrangement is based upon future net sales of the acquired business. In connection with this acquisition, we preliminarily recorded $2.7 million in goodwill and other intangible assets and $2.1 million of other net assets pending final valuation. All of the intangible assets resulting from the asset purchase are expected to be deductible for tax purposes. The financial results of the acquisition have been included in the Consolidated Financial Statements since the acquisition date.

We have entered into several customer sponsored programs administered by unrelated financial institutions that permit us to sell certain accounts receivable at discounted rates to the financial institutions. Transactions under these agreements were accounted for as sales of accounts receivable and were removed from our Consolidated Balance Sheet at the time of the sales transactions. Pursuant to these agreements, we sold $366.6$146.0 million and $391.9$135.2 million of accounts receivable during the thirty-ninethirteen weeks ended September 24,April 1, 2017 and March 26, 2016, and September 26, 2015, respectively. If receivables had not been sold, $337.3$370.6 million and $335.9$338.3 million of additional accounts receivable would have been outstanding at September 24, 2016April 1, 2017 and December 26, 2015,31, 2016, respectively, based on standard payment terms. Selling, general and administrative expenses for each of the thirty-ninethirteen weeks ended September 24,April 1, 2017 and March 26, 2016 and September 26, 2015 included $6.3$2.5 million and $5.4 million, respectively, in financing costs associated with these accounts receivable sales programs.

Inventories include the cost of material, freight, direct labor and overhead utilized in the processing of our products, and are stated at the lower of cost or market.net realizable value. Inventories were as follows:

Our 2008 Stock Option and Stock Incentive Plan (the “Plan”) was approved by our shareholders on May 20, 2009. Under the terms of the Plan, our Board of Directors may grant up to 2,000,000 shares of common stock in the form of shares of restricted stock, incentive stock options andnon-qualified stock options or combinations thereof to officers, directors, employees, consultants and advisors. Grants under the Plan must be made within ten years of the date the Plan was approved and stock options are exercisable upon the terms set forth in the grant agreement approved by the Board of Directors, but in no event more than ten years from the date of grant. Restricted stock vests in accordance with the terms set forth in each restricted stock agreement. At September 24, 2016, 1,532,856April 1, 2017, 1,406,394 shares were available for grant under the Plan.

Page 7 of 21

We grant restricted stock to certain employees and members of our Board of Directors. The value of restricted stock issued is based on the fair value of our common stock on the grant date. Vesting of restricted stock is conditional based on continued employment or service for a specified period and, in certain circumstances, the attainment of financial goals. We retain the restricted stock, and any dividends paid thereon, until the vesting conditions have been met. For awards with a service condition only, compensation cost related to the stock is recognized on a straight-line basis over the vesting period. For awards that have a service condition and require the attainment of financial goals, compensation cost related to the stock is calculated based upon the probable outcome of the performance conditions and is recognized over the vesting period if it is probable that the financial goals will be attained.performance period. Compensation cost related to restricted stock was $1.6$0.6 million and $0.7$0.4 million for the thirty-ninethirteen weeks ended September 24,April 1, 2017 and March 26, 2016, and September 26, 2015, respectively. The compensation costs were classified as selling, general and administrative expense in the Consolidated Statements of Income. No cost was capitalized during the thirty-nine weeks ended September 24, 2016 or the thirty-nine weeks ended September 26, 2015.

The following table summarizes our restricted stock activity for the thirty-ninethirteen weeks ended September 24, 2016:April 1, 2017:

As of September 24, 2016,April 1, 2017, there was approximately $4.5$7.8 million of unrecognized compensation cost related to nonvested restricted stock, which is expected to be recognized over a weighted-average period of 2.9approximately 2.8 years.

Cash flows resulting from tax deductions in excess of the tax effect of compensation cost recognized in the financial statements are classified as financingoperating cash flows. In accordance with ASUNo. 2016-09 (see Note 11), the excess tax benefit generated from restricted shares which vested in the thirteen weeks ended April 1, 2017 was $0.2 million and was credited to income tax expense. The excess tax benefit generated from restricted shares which vested was $0.2 million and $0.3 million in the thirty-ninethirteen weeks ended September 24,March 26, 2016 and September 26, 2015, respectively,was $0.1 million and was credited to additionalpaid-in capital.

We grant stock options to certain employees and members of the Board of Directors. We expense the grant-date fair value of stock options. Compensation cost is recognized on a straight-line basis over the vesting period for which related services are performed. The compensation cost charged against income for the thirty-ninethirteen weeks ended September 24,April 1, 2017 and March 26, 2016 and September 26, 2015 was less than $0.1 million in each period. The compensation costs were classified as selling, general and administrative expense in the Consolidated Statements of Income. No cost was capitalized during the thirty-ninethirteen weeks ended September 24, 2016 or the thirty-nine weeks ended SeptemberApril 1, 2017 and March 26, 2015. We included a forfeiture assumption of 5.4% in the calculation of expense in each of the thirty-nine weeks ended September 24, 2016 and September 26, 2015.2016.

We use the Black-Scholes option valuation model to estimate the fair value of stock options granted. Expected volatility and expected dividend yield are based on the actual historical experience of our common stock. The expected life represents the period of time that options granted are expected to be outstanding and was calculated using historical option exercise data. The risk-free rate was based on a U.S. Treasury security with terms equal to the expected time of exercise as of the grant date. During the thirty-ninethirteen weeks ended September 24,April 1, 2017 and March 26, 2016, we granted 61,084 stock options. There were no55,508 and 46,684 stock options, granted in the thirty-nine weeks ended September 26, 2015.respectively.

The following table summarizes our stock option activity for the thirty-ninethirteen weeks ended September 24, 2016:April 1, 2017:

No stockThere were 32,000 options were exercised during the thirty-ninethirteen weeks ended September 24, 2016.April 1, 2017. As of September 24, 2016,April 1, 2017, there was $0.5$1.2 million of unrecognized compensation cost related tonon-vested stock options, which is expected to be recognized over a weighted-average period of 3.53.6 years.

The cash received from stock option exercises was less than $0.1 million in the thirteen weeks ended April 1, 2017. There was no cash received orgenerated from stock option exercises in the thirteen weeks ended March 26, 2016.

In accordance with ASUNo. 2016-09 (see Note 11), the excess tax benefit generated from stock options exercises in the thirteen weeks ended April 1, 2017 was $0.6 million and was credited to income tax expense. There was no excess tax benefit generated from stock option exercises in the thirty-ninethirteen weeks ended September 24, 2016 or SeptemberMarch 26, 2015.2016.

Basic earnings per share is calculated by dividing our net income by the weighted average number of common shares outstanding during the period, excluding nonvested restricted stock which is considered to be contingently issuable. To calculate diluted earnings per share, common share equivalents are added to the weighted average number of common shares outstanding. Common share equivalents are calculated using the treasury stock method and are computed based on outstanding stock-based awards. Stock-based awards of approximately 16,00037,464 shares and 7,00073,000 shares were excluded from the calculation of diluted earnings per share as of September 24,April 1, 2017 and March 26, 2016, and September 26, 2015, respectively, as their effect would have been anti-dilutive.

The following table sets forth the computation of basic earnings per share and diluted earnings per share:

We periodically repurchase, at the then current market price, and cancel common stock issued to the Dorman Products, Inc. 401(k) Retirement Plan and Trust (the “401(k) Plan”). Shares are generally purchased from the 401(k) Plan when participants sell units as permitted by the 401(k) Plan or elect to leave the 401(k) Plan upon retirement, termination or other reasons. For the thirty-ninethirteen weeks ended September 24, 2016,April 1, 2017, we repurchased and cancelled 31,6903,830 shares of common stock for $1.7$0.3 million at an average price of $54.85$75.45 per share. During the fifty-twofifty-three weeks ended December 26, 2015,31, 2016, we repurchased and cancelled 33,43038,970 shares of common stock for $1.46$2.2 million at an average price of $48.14$56.66 per share.

Page 8 of 20

Our Board of Directors authorized a share repurchase program of up to $150$250 million through December 31, 2016.2018. Under this program, share repurchases may be made from time to time depending on market conditions, share price, share availability and other factors at our discretion. The share repurchase program does not obligate us to acquire any specific number of shares. For the thirty-ninethirteen weeks ended September 24, 2016,April 1, 2017, we repurchased and cancelled 329,666138,900 shares of common stock for $16.1$11.0 million at an average price of $48.81$79.43 per share under this program. For the fifty-twofifty-three weeks ended December 26, 2015,31, 2016, we repurchased and cancelled 747,700430,866 shares of common stock for $35.7$22.5 million at an average price of $47.77$52.15 per share under this program. As of September 24, 2016, we have $57.8 million remaining under this program to repurchase shares.

We have anon-cancelable operating lease for our primary operating facility with a partnership in which Steven L. Berman, our Executive Chairman, and his family members, are partners. Based upon the terms of the lease, payments will be $1.6 million in fiscal 20162017 and were $1.6 million in fiscal 2015.2016. The lease with the partnership expires December 31, 2017.2022. In the opinion of our Audit Committee, the terms and rates of this lease are no less favorable than those which could have been obtained from an unaffiliated party when the lease was renewed in fiscal 2012.2016.

We are a partner in a joint venture with one of our suppliers and own minority interests in three other suppliers. Each of these investments is accounted for according to the equity method. This includes a minority interest in two other suppliers, including Powertrain Industries, Inc. (“PTI”) whom we acquired a 40%33% minority equity interest in a supplier, which we purchased on July 19, 2016January 27, 2017 for $6.2$10.0 million. PTI is a leading manufacturer of driveshafts and driveline related products and is headquartered in Garden Grove, CA with four driveshaft manufacturing facilities located regionally throughout the United States. At any time, we can elect to purchase all of remaining capital stock of PTI. Also, between July 2019 and July 2021, the majority shareholders may require us to purchase all of the remaining capital stock of PTI. In either case, the purchase price of the shares will be determined using an earnings multiple specified in the PTI purchase agreement.

At September 24, 2016,April 1, 2017, we had $1.9$4.1 million of net unrecognized tax benefits, $1.4$2.8 million of which would affect our effective tax rate if recognized. We recognize interest and penalties related to uncertain tax positions in income tax expense. As of September 24, 2016,April 1, 2017, we had approximately $0.2 million of accrued interest related to uncertain tax positions.

We file income tax returns in the United States, China, India and Mexico. All years before 2013 are closed for federal tax purposes. We are currently under examination by one state tax authority for years 2011-2012. Tax years before 2011 are closed for the remaining states in which we file. We filed tax returns in Sweden through 2012 and all years prior to 2009 are closed. It is reasonably possible that audit settlements, the conclusion of current examinations or the expiration of the statute of limitations could impact the Company’s unrecognized tax benefits.

The carrying value of financial instruments such as cash, accounts receivable, accounts payable, and other current assets and liabilities approximate their fair value based on the short-term nature of these instruments.

In May 2014, the FASB issued ASUNo. 2014-09,Revenue from Contracts with Customers,which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. As originally issued, the new standard would have been effective for annual periods beginning after December 15, 2016. The FASB has amended the standard to be effective for annual periods beginning after December 15, 2017. The standard permits the use of either the retrospective or cumulative effect transition method.

In July 2015, the FASB issued ASUNo. 2015-11, Inventory:Simplifying the Measurement of Inventory, which changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. The amendments in this guidance do not apply to inventory that is measured usinglast-in,first-out (LIFO) or the retail inventory method. The amendments apply to all other inventory, which includes inventory that is measured usingfirst-in,first-out or average cost. Within the scope of this new guidance, an entity should measure inventory at the lower of cost and net realizable value; where, net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal,

In January 2016, the FASB issued ASUNo. 2016-01,Financial Instruments – Overall, which relates to the recognition and measurement of financial assets and liabilities. The new guidance makes targeted improvements to GAAP impacting equity investments (other than those accounted for under the equity method or consolidated), financial liabilities accounted for under the fair value election, and presentation and disclosure requirements for financial instruments, among other changes. The new guidance is effective for annual periods beginning after December 15, 2017, with early adoption prohibited other than for certain provisions.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Cautionary Statement Regarding Forward Looking Statements

Certain statements in this document constitute “forward-looking statements” within the meaning of the Federal Private Securities Litigation Reform Act of 1995. While forward-looking statements sometimes are presented with numerical specificity, they are based on various assumptions made by management regarding future circumstances over many of which the Company has little or no control. Forward-looking statements may be identified by words including “anticipate,” “believe,” “estimate,” “expect,” and similar expressions. The Company cautions readers that forward-looking statements, including, without limitation, those relating to future business prospects, revenues, working capital, liquidity, and income, are subject to certain risks and uncertainties that would cause actual results to differ materially from those indicated in the forward-looking statements. Factors that could cause actual results to differ from forward-looking statements include but are not limited to competition in the automotive aftermarket industry, unfavorable economic conditions, loss of key vendors, loss of third-party transportation providers, claims of intellectual property infringement, quality problems, delay in the development and design of new products, space limitations on our customers’ shelves, concentration of the Company’s sales and accounts receivable among a small number of customers, the impact of consolidation in the automotive aftermarket industry, foreign currency fluctuations, timing and amount of customers’ orders of Company’s products, unfavorable results of legal proceedings, dependence on the Company’s management team, disruption from events beyond the Company’s control, risks associated with conflict minerals, risks associated with cyber-attacks, the imposition of new taxes or duties, the termination or modification of accounts receivable sales agreements, and other risks and factors identified from time to time in the reports the Company files with the SEC. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. For additional information concerning factors that could cause actual results to differ materially from the information contained in this report, reference is made to the information in “Part I, Item 1A.1A Risk Factors”Factors,” in the Company’s Annual Report onForm 10-K for the fiscal year ended December 26, 2015.31, 2016. You should not place an undue reliance on forward-looking statements. Such statements speak only as to the date on which they are made, and we undertake no obligation to update publicly or revise any forward-looking statement, regardless of future developments or the availability of new information.

Introduction

The following discussion and analysis, as well as other sections in this Quarterly Report on Form10-Q, should be read in conjunction with the unaudited consolidated financial statements and footnotes thereto of Dorman Products, Inc. and its subsidiaries included in “Item 1. Financial Statements” of this Quarterly Report on Form10-Q and with Management’s Discussion and Analysis of Financial Condition and Results of Operations and the audited consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form10-K for the fiscal year ended December 26, 2015.31, 2016.

Overview

We believe we are a leading supplier of replacement parts and fasteners for passenger cars, light trucks and heavy duty trucks in the automotive aftermarket. We distribute and market approximately 150,000155,000 different stock keeping units (“SKU’s”) of automotive replacement parts many of which we design and engineer. These SKU’s are sold under our various brand names, under our customers’ private label brands or in bulk. We believe we are the dominanta leading aftermarket supplier of original equipment “dealer exclusive” items. Original equipment “dealer exclusive” parts are those parts which were traditionally available to consumers only from original equipment manufacturers or salvage yards. These parts include, among other parts, intake manifolds, exhaust manifolds, window regulators, radiator fan assemblies, tire pressure monitor sensors, complex electronics devicesmodules and exhaust gas recirculation (EGR) coolers.

We generate virtually all of our revenues from customers in the North American automotive aftermarket, primarily in the United States. Our products are sold primarily through automotive aftermarket retailers (such as Advance Auto Parts, Inc., AutoZone, Inc. and O’Reilly Auto Parts)Automotive, Inc.), national, regional and local warehouse distributors (such as Genuine Parts CoCo. - NAPA), specialty markets and salvage yards. We also distribute automotive replacement parts outside the United States, with sales primarily into Canada, Mexico, Europe, Mexico, the Middle East, Asia and Canada.Australia.

The automotive aftermarket has benefited from some of the factors affecting the general economy, including the impact of recessions, unemployment, and fluctuating gas prices. We believe vehicle owners have become more likely to keep their current vehicles longer and perform necessary repairs and maintenance in order to keep those vehicles well maintained as a result of these factors. According to data published by Polk, a division of IHS Automotive, the average age of vehicles was 11.6 years as of JanuaryNovember 2016, which is an increase from 11.5 years as of JanuaryJuly 2015 despite increasing new car sales. The number of miles driven is another important statistic that impacts our business. According to the United States Department of Transportation, the number of

Page 11 of 20

miles driven has increased each year since 2011 with miles driven having increased 3.5%3% as of November 2015December 2016 as compared to

Page 12 of 21

November 2014. December 2015. Generally, as vehicles are driven more miles, the more likely it is that parts will fail. We believe that the combination of the vehicle age increase and number of miles driven has contributed toaccounted for a portion of our sales growth.

The overall automotive aftermarket in which we compete has benefited from the conditions mentioned above. However, our customer base has been consolidating for a number of years. As a result, our customers regularly seek more favorable pricing and product return provisions, and extended payment terms when negotiating with us. We attempt to avoid or minimize these concessions as much as possible, but we have granted pricing concessions, extended customer payment terms and allowed a higher level of product returns in certain cases. These concessions impact our profit levels and may require additional capital to finance the business. We expect our customers to continue to exert pressure on our margins as the customer base continues to consolidate.

New product development is a critical success factor for us and is our primary vehicle for growth. We have made incremental investments to increase our new product development efforts each year since 2003 in an effort to grow our business and strengthen our relationships with our customers. The investments are primarily in the form of increased product development resources, increased customer andend-user awareness programs and customer service improvements. These investments have enabled us to provide an expanding array of new product offerings and grow revenues at levels that exceed market growth rates.

Our complex electronics program capitalizes on the growing number of electronic components being utilized on today’s Original Equipment platforms. Current production models contain an average of approximately thirty five electronic modules, with somehigh-end luxury vehicles containing over one hundred modules. Our complex electronics products are designed and developed in house and extensively tested to ensure consistent performance.

In 2012, we introduced a new line of products to be marketed for the medium and heavy duty truck aftermarket. We believe that this market provides many of the same opportunities for growth that the automotive aftermarket has provided us over the past several years. Our focus here is on formerly “dealer only” parts similar to the automotive side of the business. We launched the initial program with a limited offering, but have made additional investments in new product development efforts to expand our product offering. We currently have approximately 875960 SKU’s in our medium and heavy duty product line.

We may experience significant fluctuations from quarter to quarter in our results of operations due to the timing of orders placed by our customers. Generally, the second and third quarters have the highest level of net sales.

Net sales for the thirteen weeks ended September 26, 2015 included a significant benefit from stocking orders from one of our major retail customers.

Gross profit margin was 39.1% of net sales for the thirteen weeks ended September 24, 2016 and 38.3% of net sales for the thirteen weeks ended September 26, 2015. The improvement in gross profit margin was due to a favorable sales mix and lower provisions for excess inventory during the thirteen weeks ended September 24, 2016 compared to the thirteen weeks ended September 26, 2015.

Selling, general and administrative expenses were $41.5 million for the thirteen weeks ended September 24, 2016 compared to $39.6 million for the thirteen weeks ended September 26, 2015. The increase during the thirteen weeks ended September 24, 2016 was primarily due to increased investments in new product development and $0.7 million in increased incentive compensation expenses compared to the thirteen weeks ended September 26, 2015.

Our effective tax rate was 35.8% for the thirteen weeks ended September 24, 2016 and 36.7% for the thirteen weeks ended September 26, 2015. The effective income tax rate decreased primarily due to lower provisions for state income taxes and increased benefits for research and development tax credits.

Net sales increased 5% to $630.5 million for the thirty-nine weeks ended September 24, 2016 from $598.1 million for the thirty-nine weeks ended September 26, 2015.2016. The increase in net sales is primarily due to overall strongincreased demand for our products, including our new products.

Liquidity and Capital Resources

Historically, our primary sources of liquidity have been our invested cash and the cash flowsflow we generate from our operations, including accounts receivable sales programs provided by our customers. Cash and cash equivalents at September 24, 2016April 1, 2017 increased to $95.1$156.3 million from $78.7$149.1 million at December 26, 2015.31, 2016. Working capital was $429.3$453.6 million at September 24, 2016April 1, 2017 compared to $380.1$447.8 million at December 26, 2015.31, 2016. Shareholders’ equity was $579.2$620.0 million at September 24, 2016April 1, 2017 and $518.0$601.6 million at December 26, 2015.31, 2016. Based on our current operating plan, we believe that our sources of available capital are adequate to meet our ongoing cash needs for at least the next twelve months. However, our liquidity could be negatively affected by extending payment terms to customers, a decrease in demand for our products, or other factors.

Over the past several years we have continued to extend payment terms to certain customers as a result of customer requests and market demands. These extended terms have resulted in increased accounts receivable levels and significant uses of cash flows. We participate in accounts receivable sales programs with several customers which allow us to sell our accounts receivable to financial institutions to offset the negative cash flow impact of these payment terms extensions. During the thirty-ninethirteen weeks ended September 24,April 1, 2017 and March 26, 2016, and September 26, 2015, we sold approximately $366.6$146.0 million and $391.9$135.2 million, respectively, under these programs. We had the ability to sell significantly more accounts receivable under these programs if the needs of the business warranted. We expect continued pressure to extend our payment terms for the foreseeable future. Further extensions of customer payment terms will result in additional uses of cash flow or increased costs associated with the sales of accounts receivable.

We have a $30.0 million revolving credit facility which expires in June 2017. Borrowings under the facility are on an unsecured basis with interest at rates ranging from LIBOR plus 65 basis points to LIBOR plus 250 basis points based upon the achievement of certain benchmarks related to the ratio of funded debt to EBITDA, as defined by our credit agreement. The interest rate at September 24, 2016April 1, 2017 was LIBOR plus 65 basis points (1.18%(1.63%). There were no borrowings under the facility as of September 24, 2016.April 1, 2017. As of September 24, 2016,April 1, 2017, we had two outstanding letters of credit for approximately $1.0$0.8 million in the aggregate which were issued to secure ordinary course of business transactions. Net of these letters of credit, we had approximately $29.0$29.2 million available under the facility at September 24, 2016.April 1, 2017. The credit agreement also contains covenants, the most restrictive of which pertain to net worth and the ratio of debt to EBITDA. As of September 24, 2016,April 1, 2017, we were in compliance with all financial covenants contained in the revolving credit facility.

Foreign Currency Fluctuations

In fiscal 2015,2016, approximately 71%77% of our products were purchased from vendors in a variety of foreign countries. The products generally are purchased through purchase orders with the purchase price specified in U.S. Dollars. Accordingly, we generally do not have exposure to fluctuations in the relationship between the U.S. Dollar and various foreign currencies between the time of execution of the purchase order and payment for the product. To the extent that the U.S. Dollar changes in value relative to foreign currencies in the future, the price of the product for new purchase orders may change in equivalent U.S. Dollars.

The largest portion of our overseas purchases comes from China. During the thirty-nine weeks ended September 24, 2016, theThe Chinese Yuan decreased in value relative to the U.S. Dollar by approximately 3.2%. Duringexchange rate has fluctuated over the fifty-two weeks ended December 26, 2015, the Chinese Yuan decreased in value relative to the U.S. Dollar by approximately 5.4%.past several years. Any future changes in the value of the Chinese Yuan relative to the U.S. Dollar may result in a change in the cost of products that we purchase from China.

Impact of Inflation

The overall impact of inflation has not resulted in a significant change in labor costs or the cost of general services utilized. The cost of many commodities that are used in our products has fluctuated over time resulting in increases and decreases in the cost of our products. In addition, we have periodically experienced increased transportation costs as a result of higher fuel prices. We will attempt to offset cost increases by passing along selling price increases to customers, using alternative suppliers and by sourcing purchases from other countries. However there can be no assurance that we will be successful in these efforts.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our market risk is the potential loss arising from adverse changes in interest rates. Substantially all of our available credit and our accounts receivable sale programs bear interest at rates tied to LIBOR. Under the terms of our revolving credit facility and customer-sponsored programs to sell accounts receivable, a change in either the lender’s base rate, LIBOR or discount rates under our accounts receivable sale programs would affect the rate at which we could access funds thereunder. A one percentage point increase in LIBOR or the discount rates under the accounts receivable sales programs would increase our interest expense on our variable rate debt, if any, and our financing costs associated with our sales of accounts receivable by approximately $3.7 million annually. This estimate assumes that our variable rate debt balance and the level of sales of accounts receivable remains constant for an annual period and the interest rate change occurs at the beginning of the period. The hypothetical changes and assumptions may be different from what actually occurs in the future.

We have not historically and do not intend to use derivative financial instruments for trading or to speculate on changes in interest rates or commodity prices. We are not exposed to any significant market risks, foreign currency exchange risk or interest rate risk from the use of derivative instruments.

Item 4. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosures.

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, conducted an evaluation, as of the end of the period covered by this report, of the effectiveness of our disclosure controls and procedures, as such term is defined in Exchange Act Rule13a-15(e). Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures, as defined in Rule13a-15(e), were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, also conducted an evaluation of our internal control over financial reporting to determine whether any changes occurred during the quarter ended September 24, 2016April 1, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Based on that evaluation, there was no such change during the quarter ended September 24, 2016.April 1, 2017.

Limitations on the Effectiveness of Controls

Control systems, no matter how well conceived and operated, are designed to provide a reasonable, but not an absolute, level of assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. The Company conducts periodic evaluations of its internal controls to enhance, where necessary, its procedures and controls.

PART II. OTHER INFORMATION

We are a party to or otherwise involved in legal proceedings that arise in the ordinary course of business, such as various claims and legal actions involving contracts, competitive practices, intellectual property infringement, product liability claims and other matters arising out of the conduct of our business. In the opinion of management, none of the actions, individually or in the aggregate, would likely have a material financial impact on the Company and we believe the range of reasonably possible losses from current matters is immaterial.

Item 1A. Risk Factors

You should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form10-K for the year ended December 26, 2015,31, 2016, which could materially affect our business, financial condition or future results. The risks described in our Annual Report on Form10-K are not the only risks we face.
