Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note A — Basis of Presentation and Summary of Significant Accounting Policies The unaudited financial statements herein have been prepared by the Company pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The accompanying interim financial statements have been prepared under the presumption that users of the interim financial information have either read or have access to the audited financial statements for the latest fiscal year ended March 31, 2016. Accordingly, note disclosures which would substantially duplicate the disclosures contained in the March 31, 2016 audited financial statements have been omitted from these interim financial statements. The Company evaluated all subsequent events or transactions through the date of filing this report. During the period subsequent to the quarter ended September 30, 2016, the Company repurchased 61,880 shares of common stock for $2,197,000 at an average of $35.51 per share of common stock. These shares of common stock were repurchased under the Company’s ongoing share repurchase program described in Note C. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the three and six months ended September 30, 2016 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2017. For further information, refer to the consolidated financial statements and notes for the fiscal year ended March 31, 2016 included in the Company's Annual Report on Form 10-K filed with the SEC on June 10, 2016. Basis of Presentation: The consolidated financial statements include the accounts of CorVel and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates: The preparation of financial statements in compliance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the accompanying financial statements. Actual results could differ from those estimates. Significant estimates include the values assigned to intangible assets, capitalized software development, the allowance for doubtful accounts, accruals for income taxes, share-based payments related to performance-based awards, loss contingencies, estimated claims for claims administration revenue recognition, estimates used in stock option valuations, and accruals for self-insurance reserves. Cash and Cash Equivalents: Cash and cash equivalents consist of short-term, highly-liquid, investment-grade, interest-bearing securities with maturities of 90 days or less when purchased. Customer deposits represent cash that is expected to be returned or applied towards payment within one year through our provider reimbursement services. Fair Value of Financial Instruments: The Company applies Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures,” which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements with respect to fair value measurements of (a) nonfinancial assets and liabilities that are recognized or disclosed at fair value in the Company’s Consolidated Financial Statements on a recurring basis (at least annually) and (b) all financial assets and liabilities. ASC 820 prioritizes the inputs used in measuring fair value into the following hierarchy: Level 1- Quoted market prices in active markets for identical assets or liabilities; Level 2- Observable inputs other than those included in Level 1 (for example, quoted prices for similar assets in active markets or quoted prices for identical assets in inactive markets); and Level 3- Unobservable inputs reflecting management’s own assumptions about the inputs used in estimating the value of the asset. The carrying amount of the Company’s financial instruments (i.e. cash equivalents, accounts receivable, accounts payable) are all Level 1 and approximate their fair values at March 31, 2016 and September 30, 2016. The Company has no Level 2 or Level 3 financial instruments. Note A — Basis of Presentation and Summary of Significant Accounting Policies (continued) Investment in Private Equity: The Company has made an investment of $2,250,000 into a private equity limited partnership (the “partnership”) that invests in start-up companies primarily in the data analytics industry. The Company accounts for the investment on the cost method and will periodically review the investment for possible impairment. There was no impairment on the investment for the year ended March 31, 2016 and for the six months ended September 30, 2016. The investment is recorded in other assets on the accompanying consolidated balance sheets. Management has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment, and in accordance with ASC 825-10-50-16 through 50-19, it is not practicable to estimate the fair value of the investment due to the fact the investment is in a diversified portfolio of companies whose shares are not traded on the open market. Goodwill: The Company accounts for its business combinations in accordance with the FASB ASC 805-10 through ASC 805-50, “Business Combinations,” which requires that the purchase method of accounting be applied to all business combinations and addresses the criteria for initial recognition of intangible assets and goodwill. In accordance with FASB ASC 350-10 through ASC 350-30, goodwill and other intangible assets with indefinite lives are not amortized but are tested for impairment annually, or more frequently if circumstances indicate the possibility of impairment. If the carrying value of goodwill or an intangible asset exceeds its fair value, an impairment loss shall be recognized. Revenue Recognition: The Company recognizes revenue when there is persuasive evidence of an arrangement, the services have been provided to the customer, the sales price is fixed or determinable, and collectability is reasonably assured. For the Company’s services, as the Company’s professional staff performs work, they are contractually permitted to bill for fees earned in fraction of an hour increments worked or by units of production. The Company recognizes revenue as the time is worked or as units of production are completed, which is when the revenue is earned and realized. Labor costs are recognized as the costs are incurred. The Company derives its revenue from the sale of network solutions and patient management services. Network solutions and patient management services may be sold individually or combined. When a sale combines multiple elements, the Company accounts for multiple element arrangements in accordance with the guidance included in ASC 605-25. The multiple-deliverable arrangements consist of bundled managed care services, which includes various units of accounting such as network solutions, and patient management which includes claims administration. Such elements are considered separate units of accounting due to each element having value to the customer on a stand-alone basis. The selling price for each unit of accounting is determined using contract price and management estimates. When the Company’s customers purchase several products, the pricing of the products sold is generally the same as if the products were sold on an individual basis. Revenue is recognized as the work is performed in accordance with the Company’s customer contracts. Based upon the nature of the Company’s products, bundled managed care elements are generally delivered in the same accounting period. The Company recognizes revenue for patient management claims administration services over the life of the customer contract. The Company estimates, based upon prior experience in managing claims, the deferral amount from when the claim is received to when the customer contract expires. Recent Accounting Pronouncements: On May 28, 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606, . This standard provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB approved a one-year delay of the effective date of this new revenue recognition standard. The guidance will now be effective for our fiscal year beginning April 1, 2018. We are currently evaluating the accounting, transition, and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption. On November 20, 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes Note A — Basis of Presentation and Summary of Significant Accounting Policies (continued) In January 2016, the FASB issued ASU 2016-01 regarding Subtopic 825-10, Financials Instruments — Overall: Recognition and Measurements of Financial Assets and Financial Liabilities In February 2016, the FASB issued ASU No. 2016-02, Leases In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows , which reduces diversity in practice in how certain transactions are classified in the of cash flows. The new guidance is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements. Accounts Receivable: The majority of the Company’s accounts receivable is due from companies in the property and casualty insurance industries, self-insured employers, and government entities. Accounts receivable are generally due within 30 days and are stated as amounts due from customers net of an allowance for doubtful accounts. Those accounts outstanding longer than the contractual payment terms are considered past due. The Company determines its allowance by considering a number of factors, including the length of time trade accounts receivable are past due, the Company’s previous loss history, the customer’s current ability to pay its obligation to the Company and the condition of the general economy and the industry as a whole. No one customer accounted for 10% or more of accounts receivable at either March 31, 2016 or September 30, 2016. No one customer accounted for 10% or more of revenue during the three and six months ended September 30, 2015 and 2016. Property and Equipment: Additions to property and equipment are recorded at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the related assets, which range from two to seven years or the life of the lease. The Company accounts for internally developed software costs in accordance with FASB ASC 350-40, “Accounting for the Costs of Computer Software Developed or Obtained for Internal Use”, which allows for the capitalization of software developed for internal use. These costs are included in computer software in property and equipment and are amortized over a period of five years. Long-Lived Assets: The carrying amount of all long-lived assets is evaluated periodically to determine if adjustment to the depreciation and amortization period or to the unamortized balance is warranted. Such evaluation is based principally on the expected utilization of the long-lived assets and the projected, undiscounted cash flows of the operations in which the long-lived assets are deployed. Note A — Basis of Presentation and Summary of Significant Accounting Policies (continued) Income Taxes: The Company provides for income taxes in accordance with provisions specified in ASC 740, “Accounting for Income Taxes”. Accordingly, deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities. These differences will result in taxable or deductible amounts in the future, based on tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which temporary differences become deductible. In making an assessment regarding the probability of realizing a benefit from these deductible differences, management considers the Company’s current and past performance, the market environment in which the Company operates, tax-planning strategies and the length of carry-forward periods for loss carry-forwards, if any. Valuation allowances are established when necessary to reduce deferred tax assets to amounts that are more likely than not to be realized. Further, the Company provides for income tax issues not yet resolved with federal, state and local tax authorities. Earnings Per Share: Earnings per common share-basic is based on the weighted average number of common shares outstanding during the period. Earnings per common share-diluted is based on the weighted average number of common shares and common share equivalents outstanding during the period. In calculating earnings per share, earnings are the same for the basic and diluted calculations. Weighted average shares outstanding decreased in the September 2016 quarter compared to the same quarter of the prior year primarily due to repurchases of shares under the Company’s share repurchase program.

Stock-Based Compensation and Stock Options	Note B — Stock-Based Compensation and Stock Options Under the Company’s Restated Omnibus Incentive Plan (formerly the Restated 1988 Executive Stock Option Plan) (“the Plan”) as in effect at September 30, 2016, options exercisable for up to 19,365,000 shares of the Company’s common stock may be granted over the life of the Plan to key employees, non-employee directors, and consultants at exercise prices not less than the fair market value of the stock at the date of grant. Options granted under the Plan are non-statutory stock options and generally vest 25% one year from date of grant and the remaining 75% vesting ratably each month for the next 36 months. The options granted to employees and the board of directors expire at the end of five years and ten years from date of grant, respectively. The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model with the assumptions included in the table below. The Company uses historical data among other factors to estimate the expected volatility, the expected option life, and the expected forfeiture rate. The risk-free rate is based on the interest rate paid on a U.S. Treasury issue with a term similar to the estimated life of the option. Based upon the historical experience of options cancellations, the Company has estimated an annualized forfeiture rate of 12.28% and 13.16% for the three months ended September 30, 2015 and 2016, respectively. Forfeiture rates will be adjusted over the requisite service period when actual forfeitures differ, or are expected to differ, from the estimate. The following assumptions were used to estimate the fair value of options granted during the three months ended September 30, 2015 and 2016 using the Black-Scholes option-pricing model: Three Months Ended September 30, 2015 2016 Risk-free interest rate 1.61% 1.03 Expected volatility 44% 42% Expected dividend yield 0.00% 0.00% Expected forfeiture rate 12.28% 13.16% Expected weighted average life of option in years 4.4 years 4.4 years All options granted in the six months ended September 30, 2015 and 2016 were granted with an exercise price equal to the fair value of the Company’s common stock on the grant date and are non-statutory stock options. For the three months ended September 30, 2015 and 2016, the Company recorded share-based compensation expense of $488,000 and $612,000, respectively. For the six months ended September 30, 2015 and 2016, the Company recorded share-based compensation expense of $1,104,000 and $1,128,000, respectively. The table below shows the amounts recognized in the consolidated financial statements for stock compensation expense for time-based options and performance-based options during the three and six months ended September 30, 2015 and 2016, respectively.

Included in the above-noted stock option grants and stock compensation expense are performance-based stock options under which vesting occurs only upon the Company achieving certain revenue or earnings per shares targets on a calendar year basis as determined by the Company’s Board of Directors. These options were valued in the same manner as the time-vesting options. However, the Company only recognizes stock compensation to the extent that the probable targets are determined to be achieved which allow the performance options to vest. The Company recognized ($63,000) and ($31,000) of stock compensation expense for the three months ended September 30, 2015 and 2016, respectively, for performance-based stock options.

In November 2015, the Company’s Board of Directors approved a 1,000,000 share expansion to its existing stock repurchase plan, increasing the total number of shares of the Company’s common stock approved for repurchase over the life of the program to 35,000,000 shares of the Company’s common stock from the previous limit of 34,000,000 shares of the Company’s common stock. Since the commencement of the share repurchase program, the Company has spent $396 million to repurchase 33,988,013 shares of its common stock, equal to 63% of the outstanding common stock had there been no repurchases. The average price of these repurchases was $11.65 per share. These repurchases were funded primarily from the net earnings of the Company, along with the proceeds from the exercise of common stock options. During the three and six months ended September 30, 2016, the Company repurchased 63,594 shares of the Company’s common stock for $2.6 million at an average price of $40.12 per share of common stock and 101,754 shares of the Company’s common stock for $4.2 million at an average price of $41.27 per share of common stock, respectively. The Company had 19,552,218 shares of common stock outstanding as of September 30, 2016, net of the 33,988,013 shares in treasury. During the period subsequent to the quarter ended September 30, 2016, the Company repurchased 61,880 shares of common stock for $2,197,000 at an average price of $35.51 per share of common stock.

Weighted Average Shares and Net Income Per Share	Note D — Weighted Average Shares and Net Income Per Share Weighted average basic common shares decreased from 19,902,000 for the quarter ended September 30, 2015 to 19,581,000 for the quarter ended September 30, 2016. Weighted average diluted common and common equivalent shares decreased from 20,063,000 for the quarter ended September 30, 2015 to 19,733,000 for the quarter ended September 30, 2016. The net decrease in both of these weighted share calculations is due to the repurchase of common stock as noted above, offset by an increase in shares outstanding due to the exercise of stock options under the Company’s employee stock option plan. Net income per common and common equivalent shares was computed by dividing net income by the weighted average number of common and common stock equivalents outstanding during the quarter. The calculations of the basic and diluted weighted shares for the three and six months ended September 30, 2015 and 2016, are as follows: Three Months Ended September 30, 2016 2015 2016 Net Income $ 8,267,000 $ 6,952,000 Basic: Weighted average common shares outstanding 19,902,000 19,581,000 Net Income per share $ 0.42 $ 0.36 Diluted: Weighted average common shares outstanding 19,902,000 19,581,000 Treasury stock impact of stock options 161,000 152,000 Total common and common equivalent shares 20,063,000 19,733,000 Net Income per share $ 0.41 $ 0.35 Six Months Ended 2015 2016 Net Income $ 15,167,000 $ 14,443,000 Basic: Weighted average common shares outstanding 20,026,000 19,577,000 Net Income per share $ 0.76 $ 0.74 Diluted: Weighted average common shares outstanding 20,026,000 19,577,000 Treasury stock impact of stock options 173,000 166,000 Total common and common equivalent shares 20,199,000 19,743,000 Net Income per share $ 0.75 $ 0.73

Text Block [Abstract]
Shareholder Rights Plan	Note E — Shareholder Rights Plan During fiscal year 1997, the Company’s Board of Directors approved the adoption of a Shareholder Rights Plan. The Shareholder Rights Plan provides for a dividend distribution to CorVel stockholders of one preferred stock purchase right for each outstanding share of CorVel’s common stock under certain circumstances. In November 2008, the Company’s Board of Directors approved an amendment to the Shareholder Rights Plan to extend the expiration date of the rights to February 10, 2022. The rights are designed to assure that all shareholders receive fair and equal treatment in the event of any proposed takeover of the Company and to encourage a potential acquirer to negotiate with the Company’s Board of Directors prior to attempting a takeover. The rights have an exercise price of $118 per right, subject to subsequent adjustment. The rights trade with the Company’s common stock and will not be exercisable until the occurrence of certain takeover-related events. Note E — Shareholder Rights Plan (continued) Generally, the Shareholder Rights Plan provides that if a person or group acquires 15% or more of the Company’s common stock without the approval of the Board, subject to certain exceptions, the holders of the rights, other than the acquiring person or group, would, under certain circumstances, have the right to purchase additional shares of the Company’s common stock having a market value equal to two times the then-current exercise price of the right. In addition, if the Company is thereafter merged into another entity, or if 50% or more of the Company’s consolidated assets or earning power are sold, then the right will entitle its holder to buy common shares of the acquiring entity having a market value equal to two times the then-current exercise price of the right. The Company’s Board of Directors may exchange or redeem the rights under certain conditions.

Debt Disclosure [Abstract]
Line of Credit	Note G — Line of Credit In September 2016, the Company renewed a line of credit agreement. The line is with a financial institution to provide a revolving credit facility with borrowing capacity of up to $10 million. Borrowings under this agreement, as amended, bear interest, at the Company’s option, at a fixed LIBOR-based rate plus 1.50% or at a fluctuating rate determined by the financial institution to be 1.0% above the daily one-month LIBOR rate. The loan covenants require the Company to maintain the current assets to liabilities ratio of at least 1.25:1, debt to tangible net worth not greater than 1.25:1 and have positive net income. The Company is in compliance with all the covenants. There were no outstanding revolving loans as of September 30, 2016, but letters of credit in the aggregate amount of $4.5 million have been issued separate from the line of credit and therefore do not reduce the amount of borrowings available under the revolving credit facility. The renewed credit agreement expires in September 2017.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Sep. 30, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The consolidated financial statements include the accounts of CorVel and its subsidiaries. Significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates: The preparation of financial statements in compliance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the accompanying financial statements. Actual results could differ from those estimates. Significant estimates include the values assigned to intangible assets, capitalized software development, the allowance for doubtful accounts, accruals for income taxes, share-based payments related to performance-based awards, loss contingencies, estimated claims for claims administration revenue recognition, estimates used in stock option valuations, and accruals for self-insurance reserves.
Cash and Cash Equivalents	Cash and Cash Equivalents: Cash and cash equivalents consist of short-term, highly-liquid, investment-grade, interest-bearing securities with maturities of 90 days or less when purchased. Customer deposits represent cash that is expected to be returned or applied towards payment within one year through our provider reimbursement services.
Fair Value of Financial Instruments	Fair Value of Financial Instruments: The Company applies Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures,” which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements with respect to fair value measurements of (a) nonfinancial assets and liabilities that are recognized or disclosed at fair value in the Company’s Consolidated Financial Statements on a recurring basis (at least annually) and (b) all financial assets and liabilities. ASC 820 prioritizes the inputs used in measuring fair value into the following hierarchy: Level 1- Quoted market prices in active markets for identical assets or liabilities; Level 2- Observable inputs other than those included in Level 1 (for example, quoted prices for similar assets in active markets or quoted prices for identical assets in inactive markets); and Level 3- Unobservable inputs reflecting management’s own assumptions about the inputs used in estimating the value of the asset. The carrying amount of the Company’s financial instruments (i.e. cash equivalents, accounts receivable, accounts payable) are all Level 1 and approximate their fair values at March 31, 2016 and September 30, 2016. The Company has no Level 2 or Level 3 financial instruments.
Investment in Private Equity	Investment in Private Equity: The Company has made an investment of $ 2,250,000 into a private equity limited partnership (the “partnership”) that invests in start-up companies primarily in the data analytics industry. The Company accounts for the investment on the cost method and will periodically review the investment for possible impairment. There was no impairment on the investment for the year ended March 31, 2016 and for the six months ended September 30, 2016. The investment is recorded in other assets on the accompanying consolidated balance sheets. Management has not identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment, and in accordance with ASC 825-10-50-16 through 50-19, it is not practicable to estimate the fair value of the investment due to the fact the investment is in a diversified portfolio of companies whose shares are not traded on the open market.
Goodwill	Goodwill: The Company accounts for its business combinations in accordance with the FASB ASC 805-10 through ASC 805-50, “Business Combinations,” which requires that the purchase method of accounting be applied to all business combinations and addresses the criteria for initial recognition of intangible assets and goodwill. In accordance with FASB ASC 350-10 through ASC 350-30, goodwill and other intangible assets with indefinite lives are not amortized but are tested for impairment annually, or more frequently if circumstances indicate the possibility of impairment. If the carrying value of goodwill or an intangible asset exceeds its fair value, an impairment loss shall be recognized.
Revenue Recognition	Revenue Recognition: The Company recognizes revenue when there is persuasive evidence of an arrangement, the services have been provided to the customer, the sales price is fixed or determinable, and collectability is reasonably assured. For the Company’s services, as the Company’s professional staff performs work, they are contractually permitted to bill for fees earned in fraction of an hour increments worked or by units of production. The Company recognizes revenue as the time is worked or as units of production are completed, which is when the revenue is earned and realized. Labor costs are recognized as the costs are incurred. The Company derives its revenue from the sale of network solutions and patient management services. Network solutions and patient management services may be sold individually or combined. When a sale combines multiple elements, the Company accounts for multiple element arrangements in accordance with the guidance included in ASC 605-25. The multiple-deliverable arrangements consist of bundled managed care services, which includes various units of accounting such as network solutions, and patient management which includes claims administration. Such elements are considered separate units of accounting due to each element having value to the customer on a stand-alone basis. The selling price for each unit of accounting is determined using contract price and management estimates. When the Company’s customers purchase several products, the pricing of the products sold is generally the same as if the products were sold on an individual basis. Revenue is recognized as the work is performed in accordance with the Company’s customer contracts. Based upon the nature of the Company’s products, bundled managed care elements are generally delivered in the same accounting period. The Company recognizes revenue for patient management claims administration services over the life of the customer contract. The Company estimates, based upon prior experience in managing claims, the deferral amount from when the claim is received to when the customer contract expires.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: On May 28, 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606, . This standard provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB approved a one-year delay of the effective date of this new revenue recognition standard. The guidance will now be effective for our fiscal year beginning April 1, 2018. We are currently evaluating the accounting, transition, and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption. On November 20, 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes In January 2016, the FASB issued ASU 2016-01 regarding Subtopic 825-10, Financials Instruments — Overall: Recognition and Measurements of Financial Assets and Financial Liabilities In February 2016, the FASB issued ASU No. 2016-02, Leases In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows , which reduces diversity in practice in how certain transactions are classified in the of cash flows. The new guidance is effective for annual reporting periods beginning after December 15, 2017, with early adoption permitted. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements.
Accounts Receivable	Accounts Receivable: The majority of the Company’s accounts receivable is due from companies in the property and casualty insurance industries, self-insured employers, and government entities. Accounts receivable are generally due within 30 days and are stated as amounts due from customers net of an allowance for doubtful accounts. Those accounts outstanding longer than the contractual payment terms are considered past due. The Company determines its allowance by considering a number of factors, including the length of time trade accounts receivable are past due, the Company’s previous loss history, the customer’s current ability to pay its obligation to the Company and the condition of the general economy and the industry as a whole. No one customer accounted for 10% or more of accounts receivable at either March 31, 2016 or September 30, 2016. No one customer accounted for 10% or more of revenue during the three and six months ended September 30, 2015 and 2016.
Property and Equipment	Property and Equipment: Additions to property and equipment are recorded at cost. Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the related assets, which range from two to seven years or the life of the lease. The Company accounts for internally developed software costs in accordance with FASB ASC 350-40, “Accounting for the Costs of Computer Software Developed or Obtained for Internal Use”, which allows for the capitalization of software developed for internal use. These costs are included in computer software in property and equipment and are amortized over a period of five years.
Long-Lived Assets	Long-Lived Assets: The carrying amount of all long-lived assets is evaluated periodically to determine if adjustment to the depreciation and amortization period or to the unamortized balance is warranted. Such evaluation is based principally on the expected utilization of the long-lived assets and the projected, undiscounted cash flows of the operations in which the long-lived assets are deployed.
Income Taxes	Income Taxes: The Company provides for income taxes in accordance with provisions specified in ASC 740, “Accounting for Income Taxes”. Accordingly, deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities. These differences will result in taxable or deductible amounts in the future, based on tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which temporary differences become deductible. In making an assessment regarding the probability of realizing a benefit from these deductible differences, management considers the Company’s current and past performance, the market environment in which the Company operates, tax-planning strategies and the length of carry-forward periods for loss carry-forwards, if any. Valuation allowances are established when necessary to reduce deferred tax assets to amounts that are more likely than not to be realized. Further, the Company provides for income tax issues not yet resolved with federal, state and local tax authorities.
Earnings Per Share	Earnings Per Share: Earnings per common share-basic is based on the weighted average number of common shares outstanding during the period. Earnings per common share-diluted is based on the weighted average number of common shares and common share equivalents outstanding during the period. In calculating earnings per share, earnings are the same for the basic and diluted calculations. Weighted average shares outstanding decreased in the September 2016 quarter compared to the same quarter of the prior year primarily due to repurchases of shares under the Company’s share repurchase program.
