Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | 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 31 st 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. 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; ⋅ 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. Fiscal Years (In thousands) 2017 2016 2015 Gross revenues $ 373,840 $ 322,293 $ 320,404 Less: Subcontractor fees 26,041 7,217 7,572 Revenues 347,799 315,076 312,832 Reimbursements: Out-of-pocket reimbursements 7,693 5,474 5,967 Other outside direct expenses 10,442 10,405 11,160 18,135 15,879 17,127 Revenues before reimbursements $ 329,664 $ 299,197 $ 295,705 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. 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 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 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. 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. 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 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. 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. 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. Deferred revenues represent amounts billed to clients in advance of services provided. 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. 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 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. 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. 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. Revenue from Contracts with Customers 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. 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.

Fair Value Measurements | 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 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 21 15,137,000 1,370,000 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 6,396,000 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.

Stock-Based Compensation | 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 1,495,437 The ESPP allows for officers and employees to purchase common stock through payroll deductions of up to 15 95 600,000 223,429 61.33 51.97 43.88 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 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 6,341,000 The Company recorded stock-based compensation expense associated with the unvested restricted stock unit awards of $ 7,075,000 6,583,000 6,066,000 The total fair value of restricted stock unit awards vested during fiscal years 2017, 2016 and 2015 was $ 21.3 18.5 18.6 59.00 48.29 43.76 (1) Weighted-average Number Weighted-average remaining Aggregate of awards grant date contractual intrinsic value outstanding fair value term (years) (in thousands) (2) 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.

As reported by the NASDAQ Global Select Market, the market value as of December 29, 2017 was $ 71.10 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 $ 749,000 569,000 552,000 (1) Weighted-average Number Weighted-average remaining Aggregate of shares exercise contractual intrinsic value outstanding price term (years) (in thousands) Balance as of December 30, 2016 319,000 $ 31.58 Options granted 56,000 58.10 Options forfeited and expired - - Options exercised (35,000) 23.38 Balance as of December 29, 2017 340,000 $ 36.79 6.23 $ 11,665 Exercisable at December 29, 2017 204,750 $ 27.55 4.88 $ 8,917 (1) The total intrinsic value of options exercised during fiscal years 2017, 2016 and 2015 was $ 1,461,000 999,000 5,524,000 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.

Retirement Plans | 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. |

Deferred Compensation Arrangements [Abstract] | |
Deferred Compensation Plans | 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. |

Accounting Policies [Abstract] | |
Basis of Presentation | 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 31 st |
Use of Estimates | 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 | 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; ⋅ 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. Fiscal Years (In thousands) 2017 2016 2015 Gross revenues $ 373,840 $ 322,293 $ 320,404 Less: Subcontractor fees 26,041 7,217 7,572 Revenues 347,799 315,076 312,832 Reimbursements: Out-of-pocket reimbursements 7,693 5,474 5,967 Other outside direct expenses 10,442 10,405 11,160 18,135 15,879 17,127 Revenues before reimbursements $ 329,664 $ 299,197 $ 295,705 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 | 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 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 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. 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 Doubtful Accounts and Contract Losses | 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 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 | 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 | 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. |
Deferred Revenues | Deferred Revenues Deferred revenues represent amounts billed to clients in advance of services provided. |
Income Taxes | 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 | 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 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 | 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. 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 | Recent Accounting Pronouncements Not Yet Effective Revenue from Contracts with Customers 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. 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 |

[2] | 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. |
