Item 1A. Risk Factors

Exponent operates in a rapidly changing environment that involves a number of uncertainties, some of which are beyond our control and may have a material adverse effect on our financial condition and results of operations. These uncertainties include, but are not limited to, those mentioned elsewhere in this report and those set forth below.

The unpredictable and reactive nature of our business can create uneven performance in any given quarter or fiscal year.

Revenues are primarily derived from services provided in response to client requests or events that occur without notice, and engagements, generally billed as services are performed, are terminable or subject to postponement or delay at any time by clients. As a result, backlog at any particular time is small in relation to our quarterly or annual revenues and is not a reliable indicator of revenues for any future periods. Revenues and operating margins for any particular quarter are generally affected by staffing mix, resource requirements and timing and size of engagements.

Our financial results could suffer if our clients’ needs change more rapidly than we are able to secure the appropriate mix of trained, skilled and experienced personnel.

As our clients’ needs change, new technologies develop, and legal and regulatory processes change, we may be unable to timely hire or train personnel with the appropriate new set of skills and experience which could negatively impact our growth and profitability.

Failure to attract and retain key employees may adversely affect our business.

Exponent’s business involves the delivery of professional services and is labor-intensive. Our success depends in large part upon our ability to attract, retain and motivate highly qualified technical and managerial personnel. Qualified personnel are in great demand and are likely to remain a limited resource for the foreseeable future. We cannot provide any assurance that we can continue to attract sufficient numbers of highly qualified technical and managerial personnel and to retain existing employees. The loss of key managerial employees, business generators or any significant number of employees could have a material adverse impact on our business, including our ability to secure and complete engagements.

Competition could reduce our pricing and adversely affect our business.

The markets for our services are highly competitive. In addition, there are relatively low barriers to entry into our markets and we have faced, and expect to continue to face, additional competition from new entrants into our markets. Competitive pressure could reduce the market acceptance of our services and result in price reductions that could have a material adverse effect on our business, financial condition or results of operations.

The loss of a large client could adversely affect our business.

We currently derive a significant portion of our revenues from clients in the chemical, consumer electronics, energy, insurance, transportation and utilities industries and the government sector. The loss of any large client, organization or insurer could have a material adverse effect on our business, financial condition or results of operations.

Our clients may be unable to pay for our services.

If a client's financial difficulties become severe, the client may be unwilling or unable to pay our invoices in the ordinary course of business, which could adversely affect collections of both our accounts receivable and unbilled services. On occasion, some of our clients have entered bankruptcy, which has prevented us from collecting amounts owed to us. The bankruptcy of a client with substantial accounts receivable could have a material adverse effect on our financial condition and results of operations.

We hold substantial investments that could present liquidity risks.

Our cash equivalent and short-term investment portfolio as of December 29, 2017, consisted primarily of obligations of U.S. government agencies and the U.S. Treasury. We follow an established investment policy to monitor, manage and limit our exposure to interest rate and credit risk. The policy sets forth credit quality standards and limits our exposure to any one issuer, as well as our maximum exposure to various asset classes.

| 13 |

Investments in some financial instruments may pose risks arising from liquidity and credit concerns. As of December 29, 2017, we had no impairment charge associated with our investment portfolio relating to such adverse financial market conditions. Although we believe our current investment portfolio has a low risk of impairment, we cannot predict future market conditions or market liquidity and can provide no assurance that our investment portfolio will remain unimpaired.

Our business is dependent on our professional reputation.

The professional reputation of Exponent and its consultants is critical to our ability to successfully compete for new client engagements and attract or retain professionals. Proven or unproven allegations against us may damage our professional reputation. Any factors that damage our professional reputation could have a material adverse effect on our business.

Our business can be adversely impacted by deregulation or reduced regulatory enforcement.

Public concern over health, safety and preservation of the environment has resulted in the enactment of a broad range of environmental and/or other laws and regulations by local, state and federal lawmakers and agencies. These laws and the implementation of new regulations affect nearly every industry, as well as the agencies of federal, state and local governments charged with their enforcement. To the extent changes in such laws, regulations and enforcement or other factors significantly reduce the exposures of manufacturers, owners, service providers and others to liability, the demand for our services may be significantly reduced.

Tort reform can reduce demand for our services.

Several of our practices have a significant concentration in litigation support consulting services. To the extent tort reform reduces the exposure of manufacturers, owners, service providers and others to liability, the demand for our litigation support consulting services may be significantly reduced.

Our engagements may result in professional or other liability.

Our services typically involve difficult engineering and scientific assignments and carry risks of professional and other liability. Many of our engagements involve matters that could have a severe impact on a client's business, cause a client to lose significant amounts of money, or prevent a client from pursuing desirable business opportunities. Accordingly, if a client is dissatisfied with our performance, the client could threaten or bring litigation in order to recover damages or to contest its obligation to pay our fees. Litigation alleging that we performed negligently, disclosed client confidential information, lost or damaged evidence, infringed on patents, were forced to withdraw from a legal matter due to a conflict or otherwise breached our obligations to a client could expose us to significant liabilities to our clients or other third parties or tarnish our reputation.

Potential conflicts of interest may preclude us from accepting some engagements.

We provide litigation support consulting and other services primarily in connection with significant disputes, or other matters that are usually adversarial or that involve sensitive client information. The nature of our consulting services may preclude us from accepting engagements with other potential clients because of conflicts. Accordingly, the nature of our business limits the number of both potential clients and potential engagements.

We are subject to unpredictable risks of litigation.

Although we seek to avoid litigation whenever possible, from time to time we are party to various lawsuits and claims. Disputes may arise, for example, from employment issues, regulatory actions, business acquisitions and real estate and other commercial transactions. There can be no assurances that any lawsuits or claims will be immaterial in the future. Any material lawsuits or claims could adversely affect our business and reputation.

| 14 |

We may experience security breaches that could lead to the inability to protect confidential information.

Despite the implementation of security measures, our operating systems are vulnerable to electronic breaches of security. Such breaches could lead to disruptions of our operations and potential unauthorized disclosure of confidential information, which could result in legal claims or proceedings. While we have taken reasonable steps to prevent and mitigate the damage of a security breach by continuously improving our design and coordination of security controls across our business, those steps may not be effective and there can be no assurance that any such steps can be effective against all possible risks.

Impairment of goodwill may require us to record a significant charge to earnings.

On our balance sheet, we have $8,607,000 of goodwill subject to periodic evaluation for impairment. Failure to achieve sufficient levels of cash flow at reporting units, the loss of key employees, changes to the scope of operations of our business or a significant and sustained decline in our stock price could result in goodwill impairment charges. During times of financial market volatility, significant judgment is required to determine the underlying cause of the decline and whether stock price declines are short-term in nature or indicative of an event or change in circumstances.

Impairment of long-lived assets or restructuring activities may require us to record a significant charge to earnings.

Our long-lived assets, including our office, laboratory and warehouse space in Menlo Park, California and our test and engineering center in Phoenix, Arizona, are subject to periodic testing for impairment. Failure to achieve sufficient levels of cash flow at the asset group level could result in impairment of our long-lived assets. In addition, we have operating lease commitments for office, warehouse and laboratory space of $27,428,000 as of December 29, 2017. Changes in the business environment could lead to changes in the scope of operations of our business. These changes, including the closure of one or more offices, could result in restructuring and/or asset impairment charges.

Our international operations create special risks that could adversely affect our business.

In addition to our offices in the United States, we have physical offices in the United Kingdom, Germany, Switzerland, Hong Kong and China and conduct business in several other countries. We expect to continue to expand globally and our international revenues may account for an increasing portion of our revenues in the future. Our international operations carry special financial, business and legal risks, including cultural and language differences; employment laws and related factors that could result in lower utilization, higher staffing costs, and cyclical fluctuations of utilization and revenues; currency fluctuations that adversely affect our financial position and operating results; burdensome regulatory requirements and other barriers to conducting business; managing the risks associated with engagements with foreign officials and governmental agencies, including the risks arising from the United States Foreign Corrupt Practices Act and the United Kingdom Bribery Act of 2010; greater difficulties in managing and staffing foreign operations; successful entry and execution in new markets; restrictions on the repatriation of earnings; and potentially adverse tax consequences.

Inherent risks related to government contracts may adversely affect our business.

We work for various United States and foreign governmental entities and agencies. Government entities reserve the right to audit our contracts and conduct inquiries and investigations of our business practices with respect to government contracts. Findings from an audit may result in fees being refunded to the government or prospective adjustment to previously agreed upon rates that will affect future margins. If a government client discovers improper or illegal activities in the course of audits or investigations, we may become subject to various civil and criminal penalties and administrative sanctions, which may include termination of contracts, forfeiture of profits, suspension of payments, fines and suspensions or debarment from doing business with other agencies of the government. The inherent limitations of internal controls may not prevent or detect all improper or illegal activities, regardless of the adequacy of such controls. Government contracts, and the proceedings surrounding them, are often subject to more extensive scrutiny and publicity than other commercial contracts. Negative publicity related to our government contracts, regardless of whether it is accurate, may further damage our business by affecting our ability to compete for new contracts.

| 15 |

A decline in the U.S. Government budget, changes in budgetary priorities or timing of contract awards may adversely affect our business.

Our operating results could be adversely affected by spending caps or changes in the budgetary priorities of the U.S. Government, as well as delays in program starts or the award of contracts or task orders under contracts. Current U.S. Government spending levels may not be sustained and future spending and program authorizations may not increase or may decrease or shift to programs in areas in which we do not provide services or are less likely to be awarded contracts. Such changes in spending authorizations and budgetary priorities may occur as a result of the rapid growth of the federal budget deficit, increasing political pressure and legislation. The U.S. Government also conducts periodic reviews of strategies and priorities, which may shift budgetary priorities, reduce overall U.S. Government spending or delay contract or task order awards. In addition, changes to the U.S. Government acquisition system and contracting models could affect whether and how we pursue certain opportunities and the terms under which we are able to do so. A significant decline in overall U.S. Government spending, the substantial reduction or elimination of particular programs or significant delays in contract or task order awards could adversely affect our business.

Governments may terminate, cancel, modify or curtail our contracts at any time prior to their completion.

Under our government contracts, the client generally has the right not to exercise options to extend or expand our contracts and may otherwise terminate, cancel, modify or curtail our contracts at its convenience. Any decision by the client not to exercise contract options or to terminate, cancel, modify or curtail our programs or contracts would adversely affect our revenues, revenue growth and profitability.

We could incur significant liabilities and suffer negative publicity if people or properties are harmed by the products and systems we sell or the services we offer.

We design, develop, manufacture, sell, service and maintain various products and systems. In some instances, we also train operators of such products and systems. Many of these products and systems utilize software algorithms that are probabilistic in nature and subject to significant technical limitations. There are many factors, some of which are beyond our control, which could result in the failure of our products or systems. The failure of our products or systems could lead to injury, death, or extensive property damage and may lead to product liability, professional liability, or other claims against us. Further, if our products or systems fail, or are perceived to have failed, the negative publicity from such incident could have a material adverse effect on our business.

Changes in, or interpretations of, accounting principles could have a significant impact on our financial position and results of operations.

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These principles are subject to interpretation by the SEC and various bodies formed to interpret and create appropriate accounting principles. A change in these principles can have a significant effect on our reported results and may even retroactively affect previously reported transactions. Additionally, the adoption of new or revised accounting principles may require that we make significant changes to our systems, processes and controls.

Our business can be adversely affected by downturns in the overall economy.

The markets that we serve are cyclical and subject to general economic conditions. The direction and relative strength of the global economy continues to be uncertain. If economic growth in the United States, where we primarily operate, slows, our clients may consolidate or go out of business and thus demand for our services could be reduced significantly.

Our quarterly results may vary.

Variations in our revenues and operating results occur from time to time, as a result of a number of factors, such as the significance of client engagements commenced and completed during a quarter, the timing of engagements, the number of working days in a quarter, employee hiring and utilization rates, and integration of companies acquired. Because a high percentage of our expenses, particularly personnel and facilities related expenses, are relatively fixed in advance of any particular quarter, a variation in the timing of the initiation or the completion of our client assignments can cause significant variations in operating results from quarter to quarter.

| 16 |

The market price of our common stock may be volatile.

Many factors could cause the market price of our common stock to rise and fall. These include the risk factors listed above and below; changes in estimates of our performance or recommendations by securities analysts; future sales of shares of common stock in the public market; market conditions in the industry and economy as a whole; acquisitions or strategic alliances involving us or our competitors; restatement of financial results; and changes in accounting principles or methods. In addition, the stock market often experiences significant price fluctuations. These fluctuations are often unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the market price of our common stock. When the market price of a company's stock drops significantly, shareholders often institute securities class action litigation against that company. Any litigation against us could cause us to incur substantial costs, divert the time and attention of our management and other resources, or otherwise harm our business.

There can be no assurance that we will continue to declare cash dividends or repurchase our shares at all or in any particular amounts.

Our Board of Directors has declared quarterly dividends since March 2013. Our intent to continue to pay quarterly dividends and to repurchase our shares is subject to capital availability and, in the case of dividends, periodic determinations by our Board of Directors that cash dividends are in the best interest of our stockholders and are in compliance with all laws and agreements applicable to the declaration and payment of cash dividends by us. Future dividends and share repurchases may also be affected by, among other factors: our views on potential future capital requirements for investments, including acquisitions; legal risks; stock repurchase programs; changes in federal and state income tax laws or corporate laws; contractual restrictions; and changes to our business model. Our dividend payments and share repurchases may change from time to time, and we cannot provide assurance that we will continue to declare dividends or repurchase shares at all or in any particular amounts. A reduction or suspension in our dividend payments or share repurchase activity could have a negative effect on our stock price.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

Our Silicon Valley office facilities consist of a 153,738 square foot building, with office and laboratory space located on a 6.3-acre tract of land we own in Menlo Park, California and an adjacent 27,000 square feet of warehouse storage space on a 1.1-acre tract of land that we also own.

Our Test and Engineering Center (TEC) occupies 147 acres in Phoenix, Arizona. We lease this land from the state of Arizona under a 30-year lease agreement that expires in January 2028 and have options to renew for two fifteen-year periods. We constructed an indoor test facility as well as an engineering and test preparation building at the TEC.

In addition, we lease office, warehouse and laboratory space in 18 other locations in 13 states and the District of Columbia, as well as in Germany, China, Hong Kong, Switzerland and the United Kingdom. Leases for these offices, warehouse and laboratory facilities have terms generally ranging between one and ten years. Aggregate lease expense in fiscal 2017 for all leased properties was $6,712,000.

Item 3. Legal Proceedings

Exponent is not engaged in any material legal proceedings.

Item 4. Mine Safety Disclosures

We paid $21.6 million, $18.6 million and $15.5 million of dividends during fiscal 2017, 2016 and 2015, respectively. Total dividends paid per share were $0.84, $0.72 and $0.60 during fiscal 2017, 2016 and 2015, respectively. On February 1, 2018, our Board of Directors announced a quarterly cash dividend of $0.26 per share of the Company’s common stock, payable March 23, 2018, to stockholders of record as of March 2, 2018. We anticipate paying quarterly dividends each year in March, June, September and December, subject to declaration by our Board of Directors. See Part II, “Item 7: Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources.”

CRITICAL ACCOUNTING ESTIMATES

In preparing our consolidated financial statements, we make assumptions, judgments and estimates that can have a significant impact on our revenue, operating income and net income, as well as on the value of certain assets and liabilities on our consolidated balance sheet. We base our assumptions, judgments and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. On a regular basis we evaluate our assumptions, judgments and estimates and make changes accordingly. We believe that the assumptions, judgments and estimates involved in accounting for revenue recognition and estimating the allowance for contract losses and doubtful accounts have the greatest potential impact on our consolidated financial statements, so we consider these to be our critical accounting policies. We discuss below the assumptions, judgments and estimates associated with these policies. Historically, our assumptions, judgments and estimates relative to our critical accounting policies have not differed materially from actual results. For further information on our critical accounting policies, see “Note 1: Summary of Significant Accounting Policies” of our Notes to Consolidated Financial Statements.

| 20 |

Revenue recognition. We derive our revenues primarily from professional fees earned on consulting engagements, fees earned for the use of our equipment and facilities, as well as reimbursements for outside direct expenses associated with the services that are billed to our clients.

Substantially all of our engagements are service contracts performed under time and material or fixed-price billing arrangements. For time and material and fixed-price service projects, revenue is generally recognized as the services are performed. For substantially all of our fixed-price service engagements, we recognize revenue based on the relationship of incurred labor hours at standard rates to our estimate of the total labor hours at standard rates we expect to incur over the term of the contract. Our estimate of total labor hours we expect to incur over the term of the contract is based on the nature of the project and our past experience on similar projects. We believe this methodology achieves a reliable measure of the revenue from the consulting services we provide to our customers under fixed-price contracts.

Management judgments and estimates must be made and used in connection with the revenues recognized in any accounting period. These judgments and estimates include an assessment of the estimate as to the total effort required to complete fixed-price projects. If we made different judgments or utilized different estimates, the amount and timing of our revenue for any period could be materially different.

All contracts are subject to review by management, which requires a positive assessment of the collectability of contract amounts. If, during the course of the contract, we determine that collection of revenue is not reasonably assured, we do not recognize the revenue until its collection becomes reasonably assured, which in those situations would generally be upon receipt of cash. We assess collectability based on a number of factors, including past transaction history with the client, as well as the credit-worthiness of the client. Losses on fixed-price contracts are recognized during the period in which the loss first becomes evident. Contract losses are determined to be the amount by which the estimated total costs of the contract exceeds the total fixed price of the contract.

Estimating the allowance for contract losses and doubtful accounts. We make estimates of our ability to collect accounts receivable and our unbilled but recognized work-in-process. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us or for disputes with customers that affect our ability to fully collect our accounts receivable and unbilled work-in-process, we record a specific allowance to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers we recognize allowances for contract losses and doubtful accounts taking into consideration factors such as historical write-offs, customer concentration, customer credit-worthiness, current economic conditions, and aging of amounts due.

EXECUTIVE SUMMARY

Revenues for 2017 increased 10% and revenues before reimbursements also increased 10% as compared to the prior year. The increase in revenues before reimbursements was due to an increase in billable hours and an increase in billing rates. We continue to see demand for our proactive services in the areas of design and regulatory consulting, specifically related to consumer electronics. We also continue to see demand for our reactive services in construction disputes, medical device litigations, consumer product and automobile recalls, and product liability claims.

During 2017, we had strong growth in our chemical regulation & food safety, construction consulting, human factors, mechanical engineering, and polymer science & materials chemistry practices. We have been engaged to perform human factors assessments by appliance manufacturers, consumer electronics companies, medical device firms, and video game developers, including work in augmented reality. During the year, we worked on a large human factors assessment for a client in the consumer products industry, driving increases in both revenue and profitability. This project represented approximately 6% of our revenues before reimbursements for 2017 and leveraged staff across many of our practices and offices.

During the year, we increased our international construction disputes work with current mining, gas terminal and power plant projects. We also experienced growth from lithium-ion battery consulting for clients in the consumer products, transportation, medical device, and utility industries. Our interdisciplinary team of chemists, electrical engineers, materials scientists and mechanical engineers has guided clients with respect to the performance, reliability, and safety of new products, as well as with respect to recalls and litigation matters involving existing products with lithium-ion batteries.

Net income decreased to $41,305,000 during 2017 as compared to $47,480,000 during 2016. Diluted earnings per share decreased to $1.53 for 2017 as compared to $1.75 for 2016. The decrease in net income and diluted earnings per share was due to the impact of the new tax legislation. During the fourth quarter of 2017, we recorded a tax expense of $16,507,000 related to the new tax legislation signed into law during the fourth quarter of 2017. We have domestic deferred tax assets primarily associated with our deferred compensation plan and stock-based compensation program, which were previously valued at the federal corporate income tax rate of 35%. Our deferred tax assets were re-measured at the lower enacted corporate tax rate of 21% which contributed $15,137,000 to the increase in income tax associated with the new tax legislation. We also have foreign earnings that were subject to the mandatory repatriation tax. The total mandatory repatriation tax, net of the benefit of our foreign tax credits, contributed $1,370,000 to the increase in income tax expense associated with the tax legislation.

Income before income taxes increased 19% to $82,509,000 during 2017 as compared to $69,122,000 during 2016. We were able to improve pre-tax income by effectively managing headcount to align our resources with demand and benefited from a large human factors assessment for a client in the consumer products industry, which resulted in improved utilization and increased leverage of our cost structure.

We remain focused on selectively adding top talent and developing the skills necessary to expand upon our market position, providing clients with in-depth scientific research and analysis to determine what happened and how to prevent failures or exposures in the future. We also remain focused on capitalizing on emerging growth areas, managing other operating expenses, generating cash from operations, maintaining a strong balance sheet and undertaking activities such as share repurchases and dividends to enhance shareholder value.

OVERVIEW OF THE YEAR ENDED DECEMBER 29, 2017

Our revenues consist of professional fees earned on consulting engagements, fees for use of our equipment and facilities, and reimbursements for outside direct expenses associated with the services performed that are billed to our clients.

We operate on a 52-53 week fiscal year with each year ending on the Friday closest to December 31st. The fiscal years ended December 29, 2017, December 30, 2016 and January 1, 2016 included 52 weeks of activity. Fiscal 2018 will end on Friday, December 28, 2018.

During 2017, billable hours increased 9% to 1,218,000 as compared to 1,118,000 during 2016. Our utilization increased to 75% for 2017 as compared to 70% for 2016. Technical full-time equivalent employees increased 3% to 784 during 2017 as compared to 764 during 2016 due to our recruiting and retention efforts. We continue to selectively hire key talent to expand our capabilities.

FISCAL YEARS ENDED DECEMBER 29, 2017, AND DECEMBER 30, 2016

Revenues

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2017 |  |  | 2016 |  |  | Change |
Engineering and Other Scientific |  | $ | 277,603 |  |  | $ | 248,297 |  |  |  | 11.8 | %
Percentage of total revenues |  |  | 79.8 | % |  |  | 78.8 | % |  |  |  |
Environmental and Health |  |  | 70,196 |  |  |  | 66,779 |  |  |  | 5.1 | %
Percentage of total revenues |  |  | 20.2 | % |  |  | 21.2 | % |  |  |  |
Total revenues |  | $ | 347,799 |  |  | $ | 315,076 |  |  |  | 10.4 | %

The increase in revenues for our Engineering and Other Scientific segment was due to an increase in billable hours and an increase in billing rates. During 2017, billable hours for this segment increased by 9.9% to 941,000 as compared to 856,000 during 2016. The increase was due to demand for services in our construction consulting, human factors, mechanical engineering, and polymer science & materials chemistry practices. Reactive services continued to grow as our engineers and scientists were engaged to address construction disputes, medical device litigations, and consumer product and automobile recalls. Proactive services expanded, as we performed human factors assessments for consumer products and design consulting for consumer electronics. Utilization increased to 77% for 2017 as compared to 73% for 2016. Technical full-time equivalents increased 4.8% to 591 for 2017 from 564 for 2016 due to our recruiting and retention efforts.

The increase in revenues from our Environmental and Health segment was due to an increase in billable hours. During 2017, billable hours for this segment increased by 5.7% to 277,000 as compared to 262,000 during 2016. Utilization increased to 69% for 2017 as compared to 63% for 2016. During the year, the chemical regulation and food safety practice grew its proactive services to meet demand, as society remains concerned about chemicals affecting the global ecosystem and human health. Our environmental health scientists provided reactive services performing human health and environmental assessments. This segment’s contribution to the large ongoing human factors assessment also contributed to the increase in billable hours and utilization. Technical full-time equivalents decreased 3.5% to 193 during 2017 as compared to 200 for 2016 due to our efforts to align resources with anticipated demand.

| 23 |

Revenues are primarily derived from services provided in response to client requests or events that occur without notice and engagements are generally terminable or subject to postponement or delay at any time by our clients. As a result, backlog at any particular time is small in relation to our quarterly or annual revenues and is not a reliable indicator of revenues for any future periods.

Compensation and Related Expenses

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2017 |  |  | 2016 |  |  | Change |
Compensation and related expenses |  | $ | 210,289 |  |  | $ | 193,397 |  |  |  | 8.7 | %
Percentage of total revenues |  |  | 60.5 | % |  |  | 61.4 | % |  |  |  |

The increase in compensation and related expenses during 2017 was due to an increase in bonus expense, an increase in payroll expense, an increase in fringe benefits, and a change in the value of assets associated with our deferred compensation plan. During 2017, bonus expense increased by $7,718,000 due to a corresponding increase in income before income taxes, before bonus expense, and before stock-based compensation. During 2017, payroll and fringe benefits increased $4,769,000 and $991,000, respectively, due to the increase in technical full-time equivalent employees and our annual salary increase. During 2017, deferred compensation expense increased $2,686,000 with a corresponding increase to other income as compared with the prior year due to the change in value of assets associated with our deferred compensation plan. This increase consisted of an increase in the value of the plan assets of $6,547,000 during 2017 as compared to an increase in the value of the plan assets of $3,861,000 during 2016. We expect our compensation expense, excluding the change in value of deferred compensation plan assets, to increase as we selectively add new talent and adjust compensation to market conditions.

Other Operating Expenses

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2017 |  |  | 2016 |  |  | Change |
Other operating Expenses |  | $ | 29,544 |  |  | $ | 28,397 |  |  |  | 4.0 | %
Percentage of total revenues |  |  | 8.5 | % |  |  | 9.0 | % |  |  |  |

Other operating expenses include facilities-related costs, technical materials, computer-related expenses and depreciation and amortization of property, equipment and leasehold improvements. The increase in other operating expenses was primarily due to an increase in occupancy expense of $416,000, an increase in computer expense of $270,000, an increase in technical materials of $183,000, and several individually insignificant increases, which were associated with the increase in technical full-time equivalent employees and investments in our corporate infrastructure. We expect other operating expense to grow as we selectively add new talent and make investments in our corporate infrastructure.

Reimbursable Expenses

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2017 |  |  | 2016 |  |  | Change |
Reimbursable expenses |  | $ | 18,135 |  |  | $ | 15,879 |  |  |  | 14.2 | %
Percentage of total revenues |  |  | 5.2 | % |  |  | 5.0 | % |  |  |  |

The increase in reimbursable expenses was primarily due to an increase in travel related costs associated with our large human factors assessment project. The amount of reimbursable expenses will vary from year to year depending on the nature of our projects.

General and Administrative Expenses

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2017 |  |  | 2016 |  |  | Change |
General and administrative expenses |  | $ | 17,780 |  |  | $ | 15,492 |  |  |  | 14.8 | %
Percentage of total revenues |  |  | 5.1 | % |  |  | 4.9 | % |  |  |  |

The increase in general and administrative expenses during 2017 was primarily due to an increase in travel and meals of $1,173,000, an increase in contributions of $250,000, an increase in marketing and promotion of $200,000 and an increase in legal expense of $194,000. The increase in travel and meals was due to a firm-wide managers’ meeting which occurs every other year. The increase in marketing and promotion was due to several initiatives associated with the firm’s 50th anniversary. We expect general and administrative expenses to increase as we selectively add new talent, expand our business development efforts, and pursue staff development initiatives.

| 24 |

Other Income

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2017 |  |  | 2016 |  |  | Change |
Other income |  | $ | 10,458 |  |  | $ | 7,211 |  |  |  | 45.0 | %
Percentage of total revenues |  |  | 3.0 | % |  |  | 2.3 | % |  |  |  |

Other income consists primarily of interest income earned on available cash, cash equivalents and short-term investments, changes in the value of assets associated with our deferred compensation plan and rental income from leasing excess space in our Silicon Valley facility. The increase in other income was primarily due to the change in value of assets associated with our deferred compensation plan. During 2017, other income increased $2,686,000 with a corresponding increase to deferred compensation expense as compared to 2016. This change consisted of an increase in the value of the plan assets of $6,547,000 during 2017 as compared to an increase in the value of the plan assets of $3,861,000 during 2016. The increase in other income during 2017 was also due to an increase in interest income of $611,000 due to higher interest rates for our cash equivalents and short-term investments.

Income Taxes

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2017 |  |  | 2016 |  |  | Change |
Income taxes |  | $ | 41,204 |  |  | $ | 21,642 |  |  |  | 90.4 | %
Percentage of total revenues |  |  | 11.8 | % |  |  | 6.9 | % |  |  |  |
Effective tax rate |  |  | 49.9 | % |  |  | 31.3 | % |  |  |  |

The increase in income tax expense was due to an increase in pre-tax income and the impact of the new tax legislation signed into law during the fourth quarter of 2017, partially offset by an increase in the excess tax benefit associated with share-based payment awards. During 2017, we recorded a tax expense of $16,507,000 related to the new tax legislation. We have significant domestic deferred tax assets primarily associated with our deferred compensation plan and stock-based compensation program, which were previously valued at the federal corporate income tax rate of 35%. Our deferred tax assets were re-measured at the lower enacted corporate tax rate of 21%, which contributed $15,137,000 to the increase in income tax associated with the new tax legislation. We also have foreign earnings that were subject to the mandatory repatriation tax. The total mandatory repatriation tax, net of the benefit of our foreign tax credits, contributed $1,370,000 to the increase in income tax expense associated with the tax legislation.

The excess tax benefit associated with share-based payment awards increased to $6,528,000 during 2017 as compared to $4,827,000 during 2016. Excluding the impact of the new tax legislation and the excess tax benefit, the effective tax rate would have been 37.8% for 2017 as compared to 38.3% for 2016.

We expect our effective income tax rate to decrease to approximately 22% to 23% for the fiscal year ended December 28, 2018 as a result of the tax legislation.

Total revenues |  | $ | 315,076 |  |  | $ | 312,832 |  |  |  | 0.7 | %

The increase in revenues for our Engineering and Other Scientific segment was due to an increase in billable hours and an increase in billing rates. During 2016, billable hours for this segment increased by 2.5% to 856,000 as compared to 835,000 during 2015. The increase was due to demand for services in our materials & corrosion engineering, polymer science & materials chemistry, biomedical engineering, and human factors practices. The materials & corrosion engineering practice experienced growth from the utilities industry in failure analyses of systems and proactive services in asset integrity management. The polymer science & materials chemistry practice experienced growth in battery consulting services. The biomedical engineering practice realized growth in design consulting and product liability claims support. The human factors practice realized growth in user study services for the consumer products industry. This growth was partially offset by shifts in market conditions, such as reduced spending in the oil and gas industry and a slowdown in intellectual property litigation. Utilization decreased to 73% for 2016 as compared to 75% for 2015. Technical full-time equivalents increased 5.0% to 564 for 2016 from 537 for 2015 due to our recruiting and retention efforts.

| 25 |

The decrease in revenues from our Environmental and Health segment was due to a decrease in billable hours. During 2016, billable hours for this segment decreased by 9.7% to 262,000 as compared to 290,000 during 2015. Utilization decreased to 63% for 2016 as compared to 65% for 2015. The decrease in billable hours and utilization was due to completion of a major project during the third quarter of 2015 and lower revenues from the oil and gas and industrial chemicals industries. Technical full-time equivalents decreased 6.5% to 200 during 2016 as compared to 214 for 2015 due to our efforts to align resources with anticipated demand.

Percentage of total revenues |  |  | 61.4 | % |  |  | 59.0 | % |  |  |  |

The increase in compensation and related expenses during 2016 was due to an increase in payroll and a change in the value of assets associated with our deferred compensation plan. During 2016 payroll increased $4,730,000 due to the increase in technical full-time equivalent employees and our annual salary increase. During 2016, deferred compensation expense increased $4,186,000 with a corresponding increase to other income as compared with the prior year due to the change in value of assets associated with our deferred compensation plan. This increase consisted of an increase in the value of the plan assets of $3,861,000 during 2016 as compared to a decrease in the value of the plan assets of $325,000 during 2015.

Other Operating Expenses

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2016 |  |  | 2015 |  |  | Change |
Other operating Expenses |  | $ | 28,397 |  |  | $ | 26,975 |  |  |  | 5.3 | %
Percentage of total revenues |  |  | 9.0 | % |  |  | 8.6 | % |  |  |  |

Other operating expenses include facilities-related costs, technical materials, computer-related expenses and depreciation and amortization of property, equipment and leasehold improvements. The increase in other operating expenses was primarily due to an increase in depreciation expense of $652,000, an increase in occupancy expense of $344,000, an increase in computer expense of $250,000, and several individually insignificant increases, which were associated with the increase in technical full-time equivalent employees and investments in our corporate infrastructure.

Reimbursable Expenses

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2016 |  |  | 2015 |  |  | Change |
Reimbursable expenses |  | $ | 15,879 |  |  | $ | 17,127 |  |  |  | (7.3 | )%
Percentage of total revenues |  |  | 5.0 | % |  |  | 5.5 | % |  |  |  |

The decrease in reimbursable expenses was primarily due to a decrease in project-related costs in our materials & corrosion engineering, polymer science & materials chemistry, and mechanical engineering practices within our Engineering and Other Scientific segment. The amount of reimbursable expenses will vary from year to year depending on the nature of our projects.

General and Administrative Expenses

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2016 |  |  | 2015 |  |  | Change |
General and administrative expenses |  | $ | 15,492 |  |  | $ | 15,295 |  |  |  | 1.3 | %
Percentage of total revenues |  |  | 4.9 | % |  |  | 4.9 | % |  |  |  |

The increase in general and administrative expenses during 2016 was primarily due to an increase in travel and meals and bad debt partially offset by a decrease in outside consulting.

Other Income

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2016 |  |  | 2015 |  |  | Change |
Other income |  | $ | 7,211 |  |  | $ | 2,200 |  |  |  | 227.8 | %
Percentage of total revenues |  |  | 2.3 | % |  |  | 0.7 | % |  |  |  |

| 26 |

Other income consists primarily of interest income earned on available cash, cash equivalents and short-term investments, changes in the value of assets associated with our deferred compensation plan and rental income from leasing excess space in our Silicon Valley facility. The increase in other income was primarily due to the change in value of assets associated with our deferred compensation plan. During 2016, other income increased $4,186,000 with a corresponding increase to deferred compensation expense as compared to 2015. This change consisted of an increase in the value of the plan assets of $3,861,000 during 2016 as compared to a decrease in the value of the plan assets of $325,000 during 2015. The increase in other income during 2016 was also due to an increase in interest income of $476,000 and an increase in rental income of $420,000.

Income Taxes

|  | Fiscal Years |  |  | Percent |
(In thousands except percentages) |  | 2016 |  |  | 2015 |  |  | Change |
Income taxes |  | $ | 21,642 |  |  | $ | 27,534 |  |  |  | (21.4 | )%
Percentage of total revenues |  |  | 6.9 | % |  |  | 8.8 | % |  |  |  |
Effective tax rate |  |  | 31.3 | % |  |  | 38.7 | % |  |  |  |

The decrease in income taxes and the decrease in our effective tax rate were primarily due to the early adoption of ASU No. 2016-09, on a prospective basis, during the first quarter of 2016. Under ASU No. 2016-09, excess tax benefits are recorded as an income tax benefit in the consolidated statement of income. Prior to the adoption of ASU No. 2016-09, excess tax benefits were recognized in additional paid-in capital. The tax benefit realized during 2016 was $4,827,000. Excluding the excess tax benefit, the effective tax rate would have been 38.3% for 2016.

LIQUIDITY AND CAPITAL RESOURCES

|  | Fiscal Years |
(In thousands) |  | 2017 |  |  | 2016 |  |  | 2015 |
Net cash provided by (used in): |  |  |  |  |  |  |  |  |  |  |  |
Operating activities |  | $ | 67,838 |  |  | $ | 66,946 |  |  | $ | 60,489 |
Investing activities |  | $ | (17,722 | ) |  | $ | (27,443 | ) |  | $ | (27,035 | )
Financing activities |  | $ | (41,261 | ) |  | $ | (49,166 | ) |  | $ | (36,916 | )

We financed our business in 2017 through available cash and cash flows from operating activities. We invest our excess cash in cash equivalents and short-term investments. As of December 29, 2017, our cash, cash equivalents and short-term investments were $196,398,000 compared to $173,722,000 at December 30, 2016. We believe our existing balances of cash, cash equivalents and short-term investments will be sufficient to satisfy our working capital needs, capital expenditures, outstanding commitments, stock repurchases, dividends and other liquidity requirements over at least the next 12 months.

Generally, our net cash provided by operating activities is used to fund our day-to-day operating activities. First quarter operating cash requirements are generally higher due to payment of our annual bonuses accrued during the prior year. Our largest source of operating cash flows is cash collections from our clients. Our primary uses of cash from operating activities are for employee-related expenditures, leased facilities, taxes, and general operating expenses including marketing and travel.

Net cash provided by operating activities was $67.8 million for 2017 as compared to $66.9 million and $60.5 million in 2016 and 2015, respectively. The increase in net cash provided by operating activities during 2016 as compared to 2015 was primarily due to the early adoption of ASU No. 2016-09. Under ASU No. 2016-09, the excess tax benefit of $4,827,000 for 2016 was classified as an operating activity in the statement of cash flows. The excess tax benefit of $6,396,000 for 2015 was classified as a financing activity.

During 2017, 2016 and 2015, net cash used in investing activities was primarily related to the purchase and sale or maturity of short-term investments. During 2016 we completed the purchase of a 1.1 acre parcel of land with 27,000 square feet of warehouse storage space in Menlo Park, California adjacent to our owned office and lab facilities. We had leased this warehouse storage space for the past 25 years. The total purchase price was $8,250,000.

The decrease in net cash used in financing activities during 2017, as compared to 2016, was due to a decrease in repurchases of our common stock partially offset by an increase in our quarterly dividend payments. The increase in net cash used in financing activities during 2016, as compared to fiscal 2015, was primarily due to the early adoption of ASU No. 2016-09. Under ASU No. 2016-09, the excess tax benefit of $4,827,000 for 2016 was classified as an operating activity in the statement of cash flows. The excess tax benefit of $6,396,000 for 2015 was classified as a financing activity. The increase in net cash used in financing activities during fiscal 2016 was also due to an increase in our quarterly dividend payments.

| 27 |

We expect to continue our investing activities, including capital expenditures. Furthermore, cash reserves may be used to repurchase common stock under our stock repurchase programs, pay dividends, procure facilities and equipment or strategically acquire professional service firms that are complementary to our business.

The following schedule summarizes our principal contractual commitments as of December 29, 2017 (in thousands):

|  | Operating |  |  |  |  |  |  |
Fiscal |  | Lease |  |  | Purchase |  |  |  |
year |  | commitments |  |  | Obligations |  |  | Total |
2018 |  | $ | 8,442 |  |  | $ | 1,696 |  |  | $ | 10,138 |
2019 |  |  | 7,115 |  |  |  | - |  |  |  | 7,115 |

Thereafter |  |  | 4,005 |  |  |  | - |  |  |  | 4,005 |
|  | $ | 29,951 |  |  | $ | 1,696 |  |  | $ | 31,647 |

The above table does not reflect unrecognized tax benefits of $1,790,000, the timing of which is uncertain. Refer to “Note 6: Income Taxes” of the Notes to Consolidated Financial Statements for additional discussion on unrecognized tax benefits.

During April 2017, we entered into two agreements to purchase a total of 2.9 acres of land in Natick, Massachusetts on which we intend to build office and laboratory facilities. The total purchase price is $5,200,000. The purchase agreements are contingent on several items including feasibility studies, environmental assessments, and government approvals. If we determine that the property is unsuitable for the planned project, we can terminate the agreements to purchase the land at our sole discretion.

We maintain nonqualified deferred compensation plans for the benefit of a select group of highly compensated employees. Vested amounts due under the plans of $52,776,000 were recorded as a long-term liability on our consolidated balance sheet at December 29, 2017. Vested amounts due under the plans of $6,274,000 were recorded as a current liability on our consolidated balance sheet at December 29, 2017. Company assets that are earmarked to pay benefits under the plans are held in a rabbi trust and are subject to the claims of our creditors. As of December 29, 2017, invested amounts under the plans of $48,676,000 were recorded as a long-term asset on our consolidated balance sheet. As of December 29, 2017, invested amounts under the plans of $4,674,000 were recorded as a current asset on our consolidated balance sheet.

As permitted under Delaware law, we have agreements whereby we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was serving, at our request in such capacity. The indemnification period covers all pertinent events and occurrences during the officer’s or director’s lifetime. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have director and officer insurance coverage that reduces our exposure and enables us to recover a portion of any future amounts paid. We believe the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

Off-Balance Sheet Arrangements

As part of our ongoing business, we do not engage in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities.

Non-GAAP Financial Measures

Regulation G, conditions for use of Non-Generally Accepted Accounting Principles (“Non-GAAP”) financial measures, and other SEC regulations define and prescribe the conditions for use of certain Non-GAAP financial information. Generally, a Non-GAAP financial measure is a numerical measure of a company's performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. We closely monitor two financial measures, EBITDA and EBITDAS, which meet the definition of Non-GAAP financial measures. We define EBITDA as net income before income taxes, interest income, depreciation and amortization. We define EBITDAS as EBITDA before stock-based compensation. We regard EBITDA and EBITDAS as useful measures of operating performance and cash flow to complement operating income, net income and other GAAP financial performance measures. Additionally, management believes that EBITDA and EBITDAS provide meaningful comparisons of past, present and future operating results. These measures are used to evaluate our financial results, develop budgets and determine employee compensation. These measures, however, should be considered in addition to, and not as a substitute or superior to, operating income, cash flows, or other measures of financial performance prepared in accordance with GAAP. A reconciliation of the Non-GAAP measures to the nearest comparable GAAP measure is set forth below.

The following table shows EBITDA as a percentage of revenues before reimbursements for fiscal years 2017, 2016 and 2015:

|  | Fiscal Years |
(in thousands, except percentages) |  | 2017 |  |  | 2016 |  |  | 2015 |
Revenues before reimbursements |  | $ | 329,664 |  |  | $ | 299,197 |  |  | $ | 295,705 |
EBITDA |  | $ | 87,500 |  |  | $ | 74,570 |  |  | $ | 76,405 |
EBITDA as a % of revenues before reimbursements |  |  | 26.5 | % |  |  | 24.9 | % |  |  | 25.8 | %

The increase in EBITDA as a percentage of revenues before reimbursements for 2017 as compared to 2016 was primarily due to an increase in utilization. Utilization for 2017 was 75% as compared to 70% for the same period last year. The increase in utilization was due to strong demand for both our proactive and reactive services and the impact of the large human factors assessments we performed for a client in the consumer products industry.

The decrease in EBITDA as a percentage of revenues before reimbursements for 2016 as compared to 2015 was due to a decrease in utilization. Utilization for 2016 was 70% as compared to 72% during 2015. The decrease in utilization was due to the completion of a major project during the third quarter of 2015 and lower revenues from the oil and gas and industrial chemicals industries.

Item 7A. Quantitative and Qualitative Disclosure About Market Risk

Exponent is exposed to interest rate risk associated with our balances of cash, cash equivalents and short-term investments. We manage our interest rate risk by maintaining an investment portfolio primarily consisting of debt instruments with high credit quality and relatively short average effective maturities in accordance with the Company’s investment policy. The maximum effective maturity of any issue in our portfolio of cash equivalents and short-term investments is 3 years and the maximum average effective maturity of the portfolio cannot exceed 12 months.

If interest rates were to instantaneously increase or decrease by 100 basis points, the change in the fair value of our portfolio of cash equivalents and short-term investments would not have a material impact on our financial statements. We do not use derivative financial instruments in our investment portfolio. Notwithstanding our efforts to manage interest rate risk, there can be no assurances that we will be adequately protected against the risks associated with interest rate fluctuations.

We have foreign currency risk related to our revenues and expenses denominated in currencies other than the U.S. dollar, primarily the British Pound, the Euro, and the Chinese Yuan. Accordingly, changes in exchange rates may negatively affect the revenues and net income of our foreign subsidiaries as expressed in U.S. dollars.

At December 29, 2017, we had net assets of approximately $11.4 million with a functional currency of the British Pound, net assets of approximately $4.6 million with a functional currency of the Euro, and net assets of approximately $5.0 million with a functional currency of the Chinese Yuan associated with our operations in the United Kingdom, Germany, and China, respectively.

We also have foreign currency risk related to foreign currency transactions and monetary assets and liabilities denominated in currencies that are not the functional currency. We have experienced and will continue to experience fluctuations in our net income as a result of gains (losses) on these foreign currency transactions and the re-measurement of monetary assets and liabilities. At December 29, 2017, we had net assets denominated in the non-functional currency of approximately $3.5 million.

We do not use foreign exchange contracts to hedge any foreign currency exposures. To date, the impacts of foreign currency exchange rate changes on our consolidated revenues and consolidated net income have not been material. However, our continued international expansion increases our exposure to exchange rate fluctuations and as a result such fluctuations could have a significant impact on our future results of operations.

None.

Item 9A. Controls and Procedures

KPMG LLP, an independent registered public accounting firm, has audited the internal control over financial reporting of Exponent, Inc., as stated in their report which is included in Part IV, Item 15 of this Form 10-K.

| (a) | Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13(a)-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this annual report.

| (b) | Management’s Report on Internal Control Over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Our internal control over financial reporting is designed to provide reasonable assurance, but not absolute assurance, regarding the reliability of financial reporting and the preparation of financial statements in accordance with U.S. generally accepted accounting principles. There are inherent limitations to the effectiveness of any system of internal control over financial reporting. These limitations include the possibility of human error, the circumvention or overriding of the system and reasonable resource constraints. Because of its inherent limitations, our internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control - Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective at the reasonable assurance level as of December 29, 2017.

| (c) | Changes in Internal Control Over Financial Reporting.

There have not been any changes in the Company’s internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act, during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Exponent, Inc.:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Exponent, Inc. and subsidiaries (the Company) as of December 29, 2017 and December 30, 2016, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 29, 2017, and the related notes and financial statement schedule II (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of December 29, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 29, 2017 and December 30, 2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 29, 2017, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 29, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Change in Accounting Principle

The Company changed its method of accounting for excess tax benefits and tax deficiencies related to stock-based compensation as well as forfeitures of share-based awards as of January 2, 2016 due to the adoption of Accounting Standards Update 2016-09, Improvements to Employee Share-Based Payment Accounting.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control over Financial Reporting, appearing under Item 9A(b). Our responsibility is to express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

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

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

Notes to Consolidated Financial Statements

Note 1: Summary of Significant Accounting Policies

Basis of Presentation

Exponent, Inc. together with its subsidiaries (collectively referred to as the “Company”) is a science and engineering consulting firm that provides solutions to complex problems. The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.

The Company operates on a 52-53 week fiscal year with each year ending on the Friday closest to December 31st. Fiscal periods 2017, 2016 and 2015 included 52 weeks of activity and ended on December 29, 2017, December 30, 2016 and January 1, 2016, respectively. Fiscal period 2018 will end on December 28, 2018.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Estimates are used for, but not limited to, revenue recognition, allowance for contract losses and doubtful accounts, stock-based compensation, income taxes, goodwill, and investments. Actual results could differ from those estimates.

Revenue Recognition

The Company derives its revenues primarily from professional fees earned on consulting engagements, fees earned for the use of its equipment and facilities, and reimbursements for outside direct expenses associated with the services that are billed to its clients. Any taxes assessed on revenues relating to services provided to its clients are recorded on a net basis.

The Company reports service revenues net of subcontractor fees. The Company has determined that it is not the primary obligor with respect to these subcontractors because:

| · | its clients are directly involved in the subcontractor selection process;

| · | the subcontractor is responsible for fulfilling the scope of work; and

| · | the Company passes through the costs of subcontractor agreements with only a minimal fixed percentage mark-up to compensate it for processing the transactions.

Reimbursements, including those related to travel and other out-of-pocket expenses, and other similar third party costs such as the cost of materials, are included in revenues, and an equivalent amount of reimbursable expenses are included in operating expenses. Any mark-up on reimbursable expenses is included in revenues.

Substantially all of the Company’s engagements are performed under time and material or fixed-price billing arrangements. On time and material and fixed-price projects, revenue is generally recognized as the services are performed. For substantially all of the Company’s fixed-price engagements, it recognizes revenue based on the relationship of incurred labor hours at standard rates to its estimate of the total labor hours at standard rates it expects to incur over the term of the contract. The Company believes this methodology achieves a reliable measure of the revenue from the consulting services it provides to its customers under fixed-price contracts given the nature of the consulting services the Company provides and the following additional considerations:

| · | the Company considers labor hours at standard rates and expenses to be incurred when pricing its contracts;

| · | the Company generally does not incur set up costs on its contracts;

| 42 |

| · | the Company does not believe that there are reliable milestones to measure progress toward completion;

| · | if the contract is terminated early, the customer is required to pay the Company for time at standard rates plus materials incurred to date;

| · | the Company does not recognize revenue for award fees or bonuses until specific contractual criteria are met;

| · | the Company does not include revenue for unpriced change orders until the customer agrees with the changes;

| · | historically the Company has not had significant accounts receivable write-offs or cost overruns; and

| · | its contracts are typically progress billed on a monthly basis.

Gross revenues and reimbursements for fiscal years 2017, 2016 and 2015, respectively, were:

Management judgments and estimates must be made in connection with the revenues recognized in any accounting period. These judgments and estimates include an estimate as to the total effort required to complete fixed-price projects. If the Company made different judgments or utilized different estimates, the amount and timing of its revenue for any period could be materially different.

All consulting contracts are subject to review by management, which requires a positive assessment of the collectability of contract amounts. If, during the course of the contract, the Company determines that collection of revenue is not reasonably assured, it does not recognize the revenue until its collection becomes reasonably assured, which in those situations would generally be upon receipt of cash. The Company assesses collectability based on a number of factors, including past transaction history with the client, as well as the credit-worthiness of the client. Losses on fixed-price contracts are recognized during the period in which the loss first becomes evident. Contract losses are determined to be the amount by which the estimated total costs of the contract exceeds the total fixed price of the contract.

Foreign Currency Translation

The Company translates the assets and liabilities of foreign subsidiaries, whose functional currency is the local currency, at exchange rates in effect at the balance sheet date. Revenues and expenses are translated at the average rates of exchange prevailing during the year. The adjustment resulting from translating the financial statements of such foreign subsidiaries is included in accumulated other comprehensive income, which is reflected as a separate component of stockholders’ equity.

Cash Equivalents

Cash equivalents consist of highly liquid investments such as money market mutual funds, commercial paper and debt securities with original remaining maturities of three months or less from the date of purchase.

Short-term Investments

Short-term investments consist of debt securities classified as available-for-sale and are carried at their fair value as of the balance sheet date. Short-term investments generally mature between three months and three years from the purchase date. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent investments readily available for current operations.

The amortized cost of securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in interest income. Realized gains or losses are determined on the specific identification method and are reflected in other income. Net unrealized gains and losses are recorded directly in accumulated other comprehensive income except for unrealized losses that are deemed to be other-than-temporary, which are reflected in net income.

| 43 |

Investments are reviewed on a regular basis to evaluate whether or not any security has experienced an other-than temporary decline in fair value. When assessing investments for other-than-temporary declines in fair value, the Company considers the significance of the decline in value as a percentage of the original cost, how long the market value of the investment has been less than its original cost, any news that has been released specific to the investee, and the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of the investment’s cost basis.

Allowances for Contract Losses and Doubtful Accounts

The Company maintains allowances for estimated losses resulting from the inability of customers to meet their financial obligations or for disputes that affect the Company’s ability to fully collect amounts due. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations or aware of a dispute with a specific customer, a specific allowance is recorded to reduce the net recognized receivable to the amount the Company reasonably believes will be collected. For all other customers the Company recognizes allowances for doubtful accounts based upon historical write-offs, customer concentration, customer credit-worthiness, current economic conditions, aging of amounts due and changes in customer payment terms.

Property, Equipment and Leasehold Improvements

Property, equipment and leasehold improvements are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are recognized using the straight-line method. Buildings are depreciated over their estimated useful lives ranging from thirty to forty years. Equipment is depreciated over its estimated useful life, which generally ranges from two to seven years. Leasehold improvements are amortized over the shorter of their estimated useful lives, generally seven years, or the term of the related lease.

Impairment of Long-Lived Assets

The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to future undiscounted cash flows to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company has not recognized impairment losses on any long-lived assets in fiscal years 2017, 2016 or 2015.

Goodwill

The Company assesses the impairment of goodwill annually and whenever events or changes in circumstances indicate that the carrying amount may be impaired. The Company’s annual goodwill impairment review is completed during the fourth quarter of each year. The Company evaluates goodwill for each reporting unit for impairment by assessing qualitative factors to determine whether it is necessary to perform the two-step goodwill impairment test. The Company considers events and circumstances, including but not limited to, macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, changes in management or key personnel, changes in strategy, changes in customers, a change in the composition or carrying amount of a reporting unit’s net assets and changes in the price of its common stock. If, after assessing the totality of events or circumstances, the Company determines that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then the two-step goodwill impairment test is not performed.

If the two-step goodwill test is performed, the Company determines the existence of impairment by assessing the fair value of the applicable reporting unit, including goodwill, using expected future cash flows to be generated by the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of the goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation. The residual fair value after this allocation is the implied value of the reporting unit goodwill.

The Company completed its annual assessment for all reporting units with goodwill for fiscal 2017 and determined, after assessing the totality of the qualitative factors, that it is more likely than not that the fair value of each reporting unit is greater than its respective carrying amount. Accordingly there was no indication of impairment of goodwill for any of the Company’s reporting units and the two-step goodwill impairment test was not performed. The Company did not recognize any goodwill impairment losses in fiscal years 2017, 2016 or 2015.

| 44 |

Deferred Revenues

Deferred revenues represent amounts billed to clients in advance of services provided.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis and the financial reporting basis of assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates and laws in effect when the differences are expected to reverse. The effect on deferred tax assets and liabilities from changes in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. An uncertain tax position is recognized if it is determined that it is more likely than not to be sustained upon examination. The tax position is measured as the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. The Company’s policy is to recognize interest and penalties related to unrecognized tax benefits as income tax expense. Accrued interest and penalties are insignificant at December 29, 2017 and December 30, 2016.

Fair Value of Financial Instruments

Financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable, other assets and accounts payable. Cash, cash equivalents and short-term investments are recorded at fair value. The carrying amount of the Company’s accounts receivable, other assets and accounts payable approximates their fair values due to their short maturities.

Stock-Based Compensation

Stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite service period of the entire award. The Company accounts for forfeitures of share-based awards when they occur.

Net Income Per Share

Basic per share amounts are computed using the weighted-average number of common shares outstanding during the period. Dilutive per share amounts are computed using the weighted-average number of common shares outstanding and potentially dilutive securities, using the treasury stock method if their effect would be dilutive.

The following schedule reconciles the denominators of the Company’s calculation for basic and diluted net income per share:

|  | Fiscal Years |
(In thousands) |  | 2017 |  |  | 2016 |  |  | 2015 |
Shares used in basic per share computation |  |  | 26,362 |  |  |  | 26,488 |  |  |  | 26,606 |
Effect of dilutive common stock options outstanding |  |  | 145 |  |  |  | 124 |  |  |  | 135 |
Effect of unvested restricted stock units outstanding |  |  | 479 |  |  |  | 554 |  |  |  | 557 |
Shares used in diluted per share computation |  |  | 26,986 |  |  |  | 27,166 |  |  |  | 27,298 |

There were no equity awards excluded from the diluted per share calculation for fiscal years 2017, 2016 and 2015.

Recent Accounting Pronouncements Not Yet Effective. On May 28, 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 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. generally accepted accounting principles (“GAAP”) when it becomes effective. The new standard is effective for the Company on the first day of fiscal 2018 (December 30, 2017). The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application.

The impact of adopting the new standard is not expected to be material because the analysis of the Company’s contracts under the new revenue recognition standard supports the recognition of revenue over time, which is consistent with the Company’s current revenue recognition model.

| 45 |

Substantially all of the Company’s engagements are performed under time and material or fixed-price arrangements. For time and materials contracts the Company anticipates utilizing the practical expedient under the ASU which states, if an entity has a right to consideration from a customer in an amount that corresponds directly with the value of the entity’s performance completed to date (for example, a service contract in which an entity bills a fixed amount for each hour or service provided), the entity may recognize revenue in the amount to which the entity has a right to invoice. Application of the practical expedient to time and material contracts is consistent with the Company’s current revenue recognition policy.

For fixed price contracts the Company will recognize revenue over time under the ASU because of the continuous transfer of control to the customer. The customer typically controls the work in process as evidenced either by contractual termination clauses or by the Company’s rights to payment for work performed to date to deliver services that do not have an alternative use to the Company. Input methods are an acceptable method of measuring progress towards completing under the ASU. This is consistent with the Company’s current policy of measuring progress towards completion based on the relationship of incurred labor hours at standard rates to its estimate of the total labor hours at standard rates it expects to incur over the term of the contract. The Company believes this methodology achieves a reliable measure of the revenue from the consulting services it provides to its customers under fixed price contracts.

The Company anticipates adopting the standard using the modified retrospective method. The Company is currently evaluating the required disclosures under the new standard.

On February 25, 2016, the FASB issued ASU No. 2016-02, Leases, which requires lessees to recognize most leases on their balance sheet. The new standard will be effective for the Company on the first day of fiscal 2019 (December 29, 2018). Early adoption is permitted. The standard requires use of the modified retrospective transition method, with elective relief, which requires application of the guidance for all periods presented. The Company is evaluating the effect that ASU No. 2016-02 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting. The standard will require the Company to record a right of use asset and a lease liability that will materially gross up its balance sheet.

Note 3: Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including available-for-sale fixed income securities, trading fixed income and equity securities held in its deferred compensation plan and the liability associated with its deferred compensation plan. There have been no transfers between fair value measurement levels during fiscal years 2017, 2016 and 2015. Any transfers between fair value measurement levels would be recorded on the actual date of the event or change in circumstances that caused the transfer. The fair value of these certain financial assets and liabilities was determined using the following inputs at December 29, 2017 (in thousands):

At December 29, 2017 and December 30, 2016, the Company did not have any assets or liabilities valued using significant unobservable inputs.

The following financial instruments are not measured at fair value on the Company's consolidated balance sheet at December 29, 2017, but require disclosure of their fair values: accounts receivable, other assets and accounts payable. The estimated fair value of such instruments at December 29, 2017 approximates their carrying value as reported on the consolidated balance sheet.

There were no other-than-temporary impairments or credit losses related to available-for-sale securities during fiscal years 2017, 2016 and 2015.

Management believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize the net deferred tax assets.

The Tax Cuts and Jobs Act (Tax Legislation) was enacted on December 22, 2017 and lowers U.S. corporate income tax rates as of January 1, 2018, implements a territorial tax system and imposes a repatriation tax on deemed repatriated earnings of foreign subsidiaries. The estimated impact of the Tax Legislation to the Company was an increase in income tax expense of $16,507,000 during 2017. The Company’s deferred tax assets were re-measured at the lower enacted corporate tax rate of 21% which contributed $15,137,000 to the estimated increase in income tax expense associated with the Tax Legislation. The Company also has foreign earnings that were subject to the mandatory repatriation tax. The total mandatory repatriation tax, net of the benefit of the Company’s foreign tax credits, contributed $1,370,000 to the estimated increase in income tax expense associated with the Tax Legislation. The mandatory repatriation tax may be elected to be paid over a period of eight years. The Company intends to make this election.

The Tax Legislation also includes a provision to tax global intangible low-taxed income (“GILTI”) of foreign subsidiaries. The company will be subject to the GILTI provisions effective December 30, 2017 and is in the process of analyzing the effects, including how to account for the GILTI provision from an accounting policy standpoint.

Due to the change in U.S. federal tax law, the Company has decided not to indefinitely reinvest any of its unremitted foreign earnings as of December 29, 2017. Deferred U.S. state and foreign withholding taxes related to these undistributed foreign earnings are not expected to be material but are subject to further legislative action from the states regarding conformity with the Tax Legislation.

The Company is entitled to a deduction for federal and state tax purposes with respect to employees’ stock award activity. The net deduction in taxes otherwise payable arising from that deduction has been recorded as an income tax benefit for fiscal year 2017 and 2016. The net deduction in taxes otherwise payable arising from that deduction was credited to additional paid-in capital for fiscal year 2015. For fiscal years 2017, 2016 and 2015, the net deduction in tax payable arising from employees’ stock award activity was $6,528,000, $4,827,000 and $6,396,000, respectively.

The Company and its subsidiaries file income tax returns in the United States federal jurisdiction, California and various other state and foreign jurisdictions. The Company is no longer subject to United States federal income tax examination for years prior to 2014. The Company is no longer subject to California franchise tax examinations for years prior to 2013. With few exceptions, the Company is no longer subject to state and local or non-United States income tax examination by tax authorities for years prior to 2013.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

Balance at January 1, 2016 |  | $ | 1,878,000 |
Additions based on tax positions related to the current year |  |  | 502,000 |
Additions for tax positions of prior years |  |  | 6,000 |
Reductions due to lapse of statute of limitations |  |  | (430,000 | )
Settlements |  |  | - |
Balance at December 30, 2016 |  | $ | 1,956,000 |
Additions based on tax positions related to the current year |  |  | 597,000 |
Additions for tax positions of prior years |  |  | 11,000 |
Reductions due to lapse of statute of limitations |  |  | (338,000 | )
Reductions for tax positions of prior years |  |  | (437,000 | )
Settlements |  |  | - |
Balance at December 29, 2017 |  | $ | 1,789,000 |

Unrecognized tax benefits are included in other liabilities in the accompanying balance sheet. To the extent these unrecognized tax benefits are ultimately recognized, they will impact the effective tax rate by $1,459,000 in a future period. There are no uncertain tax positions whose resolution in the next 12 months is expected to materially affect operating results.

Note 8: Stock-Based Compensation

On May 29, 2008, the Company’s stockholders approved the 2008 Equity Incentive Plan and the 2008 Employee Stock Purchase Plan (“ESPP”). The 2008 Equity Incentive Plan and ESPP were previously adopted by the Company’s Board of Directors on April 8, 2008, subject to stockholder approval.

The 2008 Equity Incentive Plan allows for the award of stock options, stock awards (including stock units, stock grants and stock appreciation rights or other similar equity awards) and cash awards to officers, employees, consultants and non-employee members of the Board of Directors. The total number of shares reserved for issuance under the 2008 Equity Incentive Plan was 5,928,150 shares of common stock, subject to adjustment resulting from a stock split or the payment of a stock dividend or any other increase or decrease in the number of issued shares of the Company’s stock effected without receipt of consideration by the Company. As of December 29, 2017, 1,495,437 shares were available for grant under the 2008 Equity Incentive Plan.

The ESPP allows for officers and employees to purchase common stock through payroll deductions of up to 15% of a participant’s eligible compensation. Shares of common stock are purchased under the ESPP at 95% of the fair market value of the Company’s common stock on each purchase date. Subject to adjustment resulting from a stock split or the payment of a stock dividend or any other increase or decrease in the number of issued shares of the Company’s stock effected without receipt of consideration by the Company, the total number of shares reserved for issuance under the ESPP was 600,000 shares of common stock. As of December 29, 2017, 223,429 shares were available for grant. Weighted average purchase prices for shares sold under the ESPP plan in fiscal 2017, 2016 and 2015 were $61.33, $51.97 and $43.88, respectively.

Restricted Stock Units

The Company grants restricted stock units to employees and outside directors. These restricted stock unit grants are designed to attract and retain employees, and to better align employee interests with those of the Company’s stockholders. For a select group of employees, up to 40% of their annual bonus is settled with fully vested restricted stock unit awards. Under these fully vested restricted stock unit awards, the holder of each award has the right to receive one share of the Company’s common stock for each fully vested restricted stock unit four years from the date of grant. Each individual who received a fully vested restricted stock unit award is granted a matching number of unvested restricted stock unit awards. These unvested restricted stock unit awards cliff vest four years from the date of grant, at which time the holder of each award will have the right to receive one share of the Company’s common stock for each restricted stock unit award, provided the holder of each award has met certain employment conditions. In the case of retirement at 59 ½ years or older, all unvested restricted stock unit awards will continue to vest provided the holder of each award does all consulting work through the Company and does not become an employee for a past or present client, beneficial party or competitor of the Company.

All restricted stock units granted have dividend equivalent rights (“DER”), which entitle holders of restricted stock units to the same dividend value per share as holders of common stock. DER are subject to the same vesting and other terms and conditions as the corresponding unvested RSUs. DER are accumulated and paid when the underlying shares vest and are forfeited if the underlying shares are forfeited.

The value of these restricted stock unit awards is determined based on the market price of the Company’s common stock on the date of grant. The value of fully vested restricted stock unit awards issued is recorded as a reduction to accrued bonuses. The portion of bonus expense that the Company expects to settle with fully vested restricted stock unit awards is recorded as stock-based compensation during the period the bonus is earned. For fiscal years 2017, 2016 and 2015, the Company recorded stock-based compensation expense associated with accrued bonus awards of $8,331,000, $6,181,000 and $6,341,000, respectively.

The Company recorded stock-based compensation expense associated with the unvested restricted stock unit awards of $7,075,000, $6,583,000 and $6,066,000 during fiscal years 2017, 2016 and 2015, respectively. The total fair value of restricted stock unit awards vested during fiscal years 2017, 2016 and 2015 was $21.3 million, $18.5 million and $18.6 million, respectively. The weighted-average grant date fair values of restricted stock unit awards granted during fiscal years 2017, 2016 and 2015 were $59.00, $48.29 and $43.76, respectively.

The number of unvested restricted stock unit awards outstanding as of December 29, 2017 is as follows (1):

|  |  |  |  |  |  |  | Weighted-average |  |  |  |
|  | Number |  |  | Weighted-average |  |  | remaining |  |  | Aggregate |

Balance as of December 30, 2016 |  |  | 695,314 |  |  | $ | 37.82 |  |  |  |  |  |  |  |  |
Awards granted |  |  | 262,212 |  |  |  | 59.00 |  |  |  |  |  |  |  |  |
Awards vested |  |  | (359,174 | ) |  |  | 39.77 |  |  |  |  |  |  |  |  |
Awards forfeited |  |  | (5,760 | ) |  |  | 46.97 |  |  |  |  |  |  |  |  |
Balance as of December 29, 2017 |  |  | 592,592 |  |  | $ | 45.91 |  |  |  | 1.6 |  |  | $ | 42,133 |

| (1) | Does not include employee stock purchase plans or stock option plans.

| (2) | The intrinsic value is calculated as the market value as of the end of the fiscal period. As reported by the NASDAQ Global Select Market, the market value as of December 29, 2017 was $71.10.

| 54 |

Stock Options

The Company currently grants stock options under the 2008 Equity Incentive Plan. Options are granted for terms of ten years and generally vest ratably over a four-year period from the grant date. The Company grants options at exercise prices equal to the fair value of the Company’s common stock on the date of grant. All stock options have dividend equivalent rights (“DER”), which entitle holders of stock options to the same dividend value per share as holders of common stock. DER are subject to the same vesting terms as the corresponding stock options. DER are accumulated and paid in cash when the underlying stock options vest and are forfeited if the underlying stock options do not vest. During fiscal years 2017, 2016 and 2015, the Company recorded stock-based compensation expense of $749,000, $569,000 and $552,000, respectively, associated with stock options.

Option activity is as follows (1):

Exercisable at December 29, 2017 |  |  | 204,750 |  |  | $ | 27.55 |  |  |  | 4.88 |  |  | $ | 8,917 |

(1) Does not include restricted stock or employee stock purchase plans.

The total intrinsic value of options exercised during fiscal years 2017, 2016 and 2015 was $1,461,000, $999,000 and $5,524,000, respectively. The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of the fiscal year ended December 29, 2017, and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 29, 2017. This amount changes based on the fair-value of the Company’s stock.

The Company uses the Black-Scholes option-pricing model to determine the fair value of options granted. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include expected stock price volatility over the term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends.

The Company used historical exercise and post-vesting forfeiture and expiration data to estimate the expected term of options granted. The historical volatility of the Company’s common stock over a period of time equal to the expected term of the options granted was used to estimate expected volatility. The risk-free interest rate used in the option-pricing model was based on United States Treasury zero coupon issues with remaining terms similar to the expected term on the options. The dividend yield assumption considers the expectation of continued declaration of dividends, offset by option holders’ dividend equivalent rights. All share-based payment awards are recognized on a straight-line basis over the requisite service periods of the awards.

| 55 |

The assumptions used to value option grants for fiscal years 2017, 2016 and 2015 are as follows:

|  | Stock Option Plan |
|  | 2017 |  |  | 2016 |  |  | 2015 |
Expected term (in years) |  |  | 5.9 |  |  |  | 6.0 |  |  |  | 6.1 |
Risk-free interest rate |  |  | 2.11 | % |  |  | 1.28 | % |  |  | 1.69 | %
Volatility |  |  | 24 | % |  |  | 25 | % |  |  | 27 | %
Dividend yield |  |  | 0 | % |  |  | 0 | % |  |  | 0 | %

The weighted-average grant date fair value of options granted during fiscal years 2017, 2016 and 2015 were $16.18, $13.08 and $13.30, respectively.

The amount of stock-based compensation expense and the related income tax benefit recognized in the Company’s consolidated statements of income for fiscal years 2017, 2016 and 2015 is as follows:

|  | 2017 |  |  | 2016 |  |  | 2015 |
(In thousands) |  |  |  |  |  |  |  |  |  |  |  |
Compensation and related expenses: |  |  |  |  |  |  |  |  |  |  |  |

Income tax benefit |  | $ | 6,331 |  |  | $ | 5,214 |  |  | $ | 5,068 |

As of December 29, 2017, there was $7,570,000 of unrecognized compensation cost, expected to be recognized over a weighted average period of 2.4 years, related to unvested restricted stock unit awards and $790,000 of unrecognized compensation cost, expected to be recognized over a weighted average period of 2.7 years, related to unvested stock options.

Note 9: Retirement Plans

The Company provides a defined contribution retirement plan for its employees whereby the Company contributes to each eligible employee’s account 7% of the employee’s eligible base salary plus overtime. The employee does not need to make a contribution to the plan to be eligible for the Company’s 7% contribution. To be eligible under the plan, an employee must be at least 21 years of age and be either a full-time or part-time salaried employee. The 7% Company contribution will vest 20% per year for the first 5 years of employment and then immediately thereafter. The Company’s expenses related to this plan were $7,914,000, $7,761,000, and $7,317,000 in fiscal years 2017, 2016, and 2015, respectively.

Note 10: Deferred Compensation Plans

The Company maintains nonqualified deferred compensation plans for the benefit of a select group of highly compensated employees. Under these plans, participants may elect to defer up to 100% of their compensation. Company assets that are earmarked to pay benefits under the plans are held in a rabbi trust and are subject to the claims of the Company’s creditors. As of December 29, 2017 and December 30, 2016 the invested amounts under the plans totaled $53,350,000 and $48,267,000, respectively. These assets are classified as trading securities and are recorded at fair market value with changes recorded as adjustments to other income.

As of December 29, 2017 and December 30, 2016, vested amounts due under the plans totaled $59,050,000 and $53,617,000, respectively. Changes in the liability are recorded as adjustments to compensation expense. During fiscal years 2017, 2016 and 2015, the Company recognized compensation expense of $6,547,000, $3,861,000, and $(325,000), respectively, as a result of changes in the market value of the trust assets with the same amount being recorded as other income.

(1) The decrease in net income and diluted earnings per share during the fourth quarter of 2017 was due to the impact of the new tax legislation. During the fourth quarter of 2017, the Company recorded a tax expense of $16,507,000 related to the new tax legislation signed into law during the fourth quarter of 2017. The Company has domestic deferred tax assets primarily associated with its deferred compensation plan and stock-based compensation program, which were previously valued at the federal corporate income tax rate of 35%. The Company’s deferred tax assets were re-measured at the lower enacted corporate tax rate of 21% which contributed $15,137,000 to the increase in income tax associated with the new tax legislation. The Company also has foreign earnings that were subject to the mandatory repatriation tax. The total mandatory repatriation tax, net of the benefit of its foreign tax credits, contributed $1,370,000 to the increase in income tax expense associated with the tax legislation.
