Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Principles of Consolidation
	The consolidated financial statements of CPSI include the accounts of TruBridge, a wholly-owned subsidiary of CPSI. All significant intercompany balances and transactions have been eliminated.
	Cash and Cash Equivalents
	Cash and cash equivalents can include time deposits and certificates of deposit with original maturities of three months or less that are highly liquid and readily convertible to a known amount of cash. These assets are stated at cost, which approximates market value, due to their short duration or liquid nature.
	Investments
	The Company accounts for investments in accordance with FASB Codification topic, Investments – Debt and Equity Securities. Accordingly, investments are classified as available-for-sale securities and are reported at fair value, with unrealized gains and losses excluded from earnings and reported in a separate component of stockholders’ equity. The Company’s management determines the appropriate classifications of investments in fixed maturity securities at the time of acquisition and re-evaluates the classifications at each balance sheet date. An average cost method is used for purposes of determining the cost of investments sold.
	Income Taxes
	We account for income taxes in accordance with FASB Codification topic – Income Taxes. Under this topic, deferred income taxes are determined utilizing the asset and liability approach. This method gives consideration to the future tax consequences associated with differences between financial accounting and tax bases of assets and liabilities. The effect on the deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We recognize interest and penalties accrued related to unrecognized tax benefits in the consolidated statements of income as a component of the provision for income taxes.
	We also make a provision for uncertain income tax positions in accordance with the Income Taxes Codification topic. These provisions require that a tax position taken in a tax return be recognized in the financial statements when it is more likely than not (i.e., a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon settlement. The topic also requires that changes in judgment that result in subsequent recognition, derecognition, or change in a measurement date of a tax position taken in a prior annual period (including any related interest and penalties) be recognized as a discrete item in the interim period in which the change occurs.
	Accounts Receivable and Allowance for Doubtful Accounts
	Trade accounts receivable are stated at the amount the Company expects to collect and do not bear interest. The Company establishes a general allowance for doubtful accounts based on collections history. In the case of a bankruptcy filing or other similar event indicating the collectability of specific customer accounts is no longer probable, a specific reserve for bad debt may be recorded to reduce the related receivable to the amount expected to be recovered.
	Financing Receivables
	Financing receivables are comprised of short-term payment plans and sales-type leases. Short-term payment plans are stated at the amount the Company expects to collect and do not bear interest. Sales-type leases are initially recorded at the present value of the related minimum lease payments, computed at the interest rate implicit in the lease, and are presented net of unearned income. Unearned income is amortized over the lease term to produce a constant periodic rate of return on the net investment in the lease (the interest method).
	An allowance for credit losses has been established for our financing receivables based on the historical level of customer defaults under such arrangements. In the case of a bankruptcy filing or other similar event indicating the collectability of specific customer accounts is no longer probable, a specific reserve may be recorded to reduce the related receivable to the amount expected to be recovered. Customer payments are considered past due if a scheduled payment is not received within contractually agreed upon terms, with amounts reclassified to accounts receivable when they become due. As a result, we evaluate the credit quality of our financing receivables on an ongoing basis utilizing an aging of receivables and write-offs, customer collection experience, the customer’s financial condition and known risk characteristics impacting the respective customer base, as well as existing economic conditions, to determine if any further allowance is necessary. Amounts are specifically charged off once all available means of collection have been exhausted.
	Inventories
	Inventories are stated at lower of cost or market using the average cost method. The Company’s inventories are comprised of computer equipment, forms and supplies. For cash flow presentation, inventory used by the Company and capitalized as property and equipment is shown as a change in inventory.
	Property and Equipment
	Property and equipment is recorded at cost, less accumulated depreciation. Additions and improvements to property and equipment that materially increase productive capacity or extend the life of an asset are capitalized. Maintenance, repairs and minor renewals are expensed as incurred. Upon retirement or other disposition of such assets, the related costs and accumulated depreciation are removed from the respective accounts and any resulting gain or loss is included in the results of operations.
	Depreciation expense is computed using the straight-line method over the asset’s useful life, which is generally 5 years for computer equipment, furniture, and fixtures and 30 years for buildings. Leasehold improvements are depreciated over the shorter of the asset’s useful life or the remaining lease term. The Company reviews for the possible impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Depreciation expense is reported in the consolidated statements of income as a component of support and maintenance costs and operating expenses.
	Deferred Revenue
	Deferred revenue represents amounts received from customers under licensing agreements and implementation fees for which the revenue recognition process has not been completed.
	Revenue Recognition
	The Company recognizes revenue in accordance with accounting principles generally accepted in the United States of America ("US GAAP"), principally those required by the Software topic and Revenue Recognition subtopic of the Codification and those prescribed by the Securities and Exchange Commission (the "SEC").
	The Company's revenue is generated from three sources:
	•	System Sales - the sale of information systems, which includes perpetual software licenses, conversion, installation and training services, hardware and peripherals;
	•	Support and Maintenance - the provision of system support services, which includes software application support, hardware maintenance, continuing education, "Software as a Service" (or "SaaS") services, and forms and supplies; and
	•	Business Management, Consulting and Managed IT Services - the provision of business management services, which includes electronic billing, statement processing, payroll processing, accounts receivable management, contract management and insurance services, as well as Internet service provider ("ISP") services and consulting and managed IT services (collectively, "other professional IT services").
	System Sales, Software Application Support and Hardware Maintenance
	The Company enters into contractual obligations to sell perpetual software licenses, conversion, installation and training services, hardware and software application support and hardware maintenance services. On average, the Company is able to complete a system installation in three to four weeks. The methods employed by the Company to recognize revenue, which are discussed by element below, achieve results materially consistent with the provisions of Accounting Standards Update ("ASU") 2009-13, Multiple-Deliverable Revenue Arrangements, due to the relatively short period during which there are multiple undelivered elements, the relatively small amount of non-software related elements in the system sale arrangements, and the limited number of contracts in-process at the end of each reporting period. The Company recognizes revenue on the elements noted above as follows:
	•	Perpetual software licenses and conversion, installation and training services – The selling price of perpetual software licenses and conversion, installation and training services is based on management’s best estimate of selling price. In determining management’s best estimate of selling price, we consider the following: (1) competitor pricing, (2) supply and demand of installation staff, (3) overall economic conditions, and (4) our pricing practices as they relate to discounts. With the exception of certain arrangements with extended payment terms that were entered into in 2012 and that are not comparable to our historical or current arrangements (see Note 10), the method of recognizing revenue for the perpetual license of the associated modules included in the arrangement, and the related conversion, installation and training services over the term the services are performed, is on a module by module basis as the related perpetual licenses are delivered and the respective conversion, installation and training for each specific module is completed, as this is representative of the pattern of provision of these services.
	•	Hardware – We recognize revenue for hardware upon shipment. The selling price of hardware is based on management’s best estimate of selling price, which consists of cost plus a targeted margin.
	•	Software application support and hardware maintenance – We have established vendor-specific objective evidence ("VSOE") of the fair value of our software application support and hardware maintenance services by reference to the price our customers are required to pay for the services when sold separately via renewals. Support and maintenance revenue is recognized on a straight-line basis over the term of the maintenance contract, which is generally three to five years.
	SaaS, ISP and Other Professional IT Services
	The Company accounts for SaaS arrangements in accordance with the requirements of the Hosting Arrangement section under the Software topic and Revenue Recognition subtopic of the Codification. The Codification states that the software elements of SaaS services should not be accounted for as a hosting arrangement "if the customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty and it is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software." Each SaaS contract entered into by the Company includes a system purchase and buyout clause, and this clause specifies the total amount of the system buyout. In addition, a clause is included in the contract which states that should the system be bought out by the customer, the customer would be required to enter into a general support agreement (for post-contract support services) for the remainder of the original SaaS term. Accordingly, the Company has concluded that SaaS customers do not have the right to take possession of the system without significant penalty (i.e., the purchase price of the system), resulting in the determination that these contracts are service contracts for which revenue is recognized when the services are performed.
	The Company will occasionally provide ISP and other professional IT services. Depending on the nature of the services provided, these services may be considered software elements or non-software elements. The selling price of services considered to be software elements is based on VSOE of the fair value of the services by reference to the price our customers are required to pay for the services when sold separately. The selling price of services considered to be non-software elements is based on third-party evidence of selling price of similar services. Revenue from these elements are recognized as the services are performed.
	Business Management Services
	Business management services consist of electronic billing, statement processing, payroll processing, accounts receivable management, contract management and insurance services. While business management service arrangements are contracts separate from the system sale and support and maintenance contracts, these contracts are often executed within a short time frame of each other. The amount of the total arrangement allocated to these services is based on VSOE of fair value by reference to the rate at which our customers renew as well as the rate at which the services are sold to customers when the business management services agreement is not executed within a short time frame of the system sale and support and maintenance contracts. If VSOE of fair value does not exist for these services, we allocate arrangement consideration based on third-party evidence ("TPE") of selling price or, if neither VSOE nor TPE is available, estimated selling price. Because the pricing is transaction based (per unit pricing), customers are billed and revenue recognized as services are performed based on transaction levels.
	Stock-Based Compensation
	The Company accounts for stock-based compensation according to the provisions of FASB Codification topic, Compensation – Stock Compensation, which establishes accounting for stock-based awards exchanged for employee services. Accordingly, stock-based compensation cost is measured at the grant date based on the fair value of the award, and is recognized as an expense over the employee’s or non-employee director’s requisite service period.
	Research and Development Costs
	Research and development costs are expensed as incurred. Research and development costs totaled approximately $2,866,000, $2,761,000 and $2,757,000 for the years ended December 31, 2014, 2013 and 2012, respectively. Research and development costs are included in costs of support and maintenance in the accompanying consolidated statements of income.
	Advertising
	Advertising costs are expensed as incurred. Advertising expense was approximately $93,000, $97,000 and $132,000 for the years ended December 31, 2014, 2013 and 2012, respectively, and is recorded in sales and marketing expenses in the accompanying consolidated statements of income.
	Shipping and Handling Costs
	Shipping and handling costs are expensed as incurred and included in general and administrative expenses and costs of business management, consulting and managed IT services. Shipping and handling costs totaled approximately $571,000, $491,000 and $617,000 for the years ended December 31, 2014, 2013 and 2012, respectively.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the financial statements, and the reported revenues and expenses during the reporting periods. Actual results could differ from those estimates.
	New Accounting Standards Adopted in 2014
	There were no new standards required to be adopted during the year ended December 31, 2014 that had or will have a material impact on our financial statements.
	New Accounting Standards Yet to be Adopted
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, to clarify the principles for recognizing revenue and to develop a common revenue standard for US GAAP and International Financial Reporting Standards. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes the most current revenue recognition guidance. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2016, which is effective for the Company as of the first quarter of our fiscal year ending December 31, 2017. The Company is currently evaluating the impact that the implementation of this standard will have on its financial statements.

	Our investment portfolio, including those securities in unrealized loss positions at December 31, 2014, is comprised almost entirely of investment-grade corporate and government debt securities and certificates of deposit with large financial institutions. The Company does not intend to sell the investments that are in an unrealized loss position, and it is not likely that the Company will be required to sell any investments before recovery of their amortized cost basis. As a result, the Company has determined that the unrealized losses are deemed to be temporary impairments as of December 31, 2014. The Company believes that the unrealized losses generally are caused by liquidity discounts and increases in risk premiums required by market participants rather than an adverse change in cash flows or a fundamental weakness in the credit quality of the issuer or underlying assets.

Earnings Per Share [Abstract]
Net Income Per Share	NET INCOME PER SHARE
	The Company presents basic and diluted earnings per share ("EPS") data for its common stock. Basic EPS is calculated by dividing the net income attributable to stockholders of the Company by the weighted average number of shares of common stock outstanding during the period. Diluted EPS is determined by adjusting the net income attributable to stockholders of the Company and the weighted average number of shares of common stock outstanding during the period for the effects of all dilutive potential common shares, including awards under stock-based compensation arrangements.
	The Company's unvested restricted stock awards (see Note 8) are considered participating securities under FASB Codification topic, Earnings Per Share, because they entitle holders to non-forfeitable rights to dividends until the awards vest or are forfeited. When a company has a security that qualifies as a "participating security," the Codification requires the use of the two-class method when computing basic EPS. The two-class method is an earnings allocation formula that determines EPS for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. In determining the amount of net income to allocate to common stockholders, income is allocated to both common stock and participating securities based on their respective weighted average shares outstanding for the period, with net income attributable to common stockholders ultimately equaling net income less net income attributable to participating securities. Diluted EPS for the Company's common stock is computed using the more dilutive of the two-class method or the treasury stock method.
	The following is a calculation of the basic and diluted EPS for the Company's common stock, including a reconciliation between net income and net income attributable to common stockholders:

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES
	The Company accounts for income taxes in accordance with the FASB’s Codification topic, Income Taxes. These provisions require a company to determine whether it is more likely than not that a tax position will be sustained upon examination based on the technical merits of the position. If the more-likely-than-not threshold is met, a company must measure the tax position to determine the amount to recognize in the financial statements.
	We applied these provisions to all tax positions for which the statute of limitations remained open. A reconciliation of the beginning and ending amount of unrecognized tax benefit, included as a component of "Income taxes payable" or "Prepaid income taxes" (as determined by the status of the Company's overall federal and state income tax position at the respective balance sheet dates) within the Consolidated Balance Sheets, is as follows:
		2014			2013
	Beginning balance	$	1,317,977		$	744,705
	Additions based on tax positions related to the current year	112,492			62,800
	Additions for tax positions of prior years	25,402			580,099
	Reductions for tax positions of prior years	—			(69,627		)
	Ending balance	$	1,455,871		$	1,317,977
	The total amount of unrecognized tax benefits, if recognized, that would affect the effective tax rate is $1,455,871.
	The Company classifies interest and penalties arising from the underpayment of income taxes in the consolidated statements of income under provision for income taxes. As of December 31, 2014, we had recorded $143,997 of accrued interest related to uncertain tax positions. The federal returns for the tax years 2004 through 2009 are currently under examination by the Internal Revenue Service, primarily in relation to research credits claimed on those returns, as amended, by the Company. The federal returns for tax years 2010 through 2013 remain open to examination, and the tax years 2006 through 2013 remain open to examination by certain other taxing jurisdictions to which the Company is subject.
	It is reasonably possible that the amount of unrecognized tax benefits, inclusive of related interest, will change in the next twelve months. At December 31, 2014, there is no estimated increase or decrease in the amount of unrecognized tax benefits.
	Deferred income taxes arise from the temporary differences in the recognition of income and expenses for tax purposes. A valuation allowance is established when the Company believes that it is more likely than not that some portion of its deferred tax assets will not be realized. Deferred tax assets and liabilities are comprised of the following at December 31, 2014 and 2013:
		2014			2013
	Deferred tax assets:
	Accounts receivable and financing receivables	$	879,094		$	971,132

	The difference between income taxes at the U.S. federal statutory income tax rate of 35% and those reported in the consolidated statements of income for the years ended December 31, 2014, 2013 and 2012 are as follows:

	Our effective tax rates for the years ended December 31, 2014, 2013 and 2012 were 33.81%, 35.43% and 28.63%, respectively. The significantly reduced effective tax rate for the year ended December 31, 2012 (when compared to both 2013 and 2014) is mostly due to provision-to-return adjustments recorded during 2012, primarily related to differences between the DPAD amount reported on the 2011 federal income tax return and amounts previously estimated, as well as the expected additional net federal tax benefit to be realized by the Company upon amending federal income tax returns for all open years for revised DPAD amounts.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Based Compensation	STOCK-BASED COMPENSATION
	The Company's stock-based compensation awards are in the form of restricted stock and performance share awards made pursuant to the Company's 2005 Restricted Stock Plan, 2012 Restricted Stock Plan for Non-Employee Directors, and 2014 Incentive Plan (the "Plans"). Stock-based compensation cost is measured at the grant date based on the fair value of the award, and is recognized as an expense over the employee’s or non-employee director’s requisite service period. As of December 31, 2014, there were a total of 608,836 shares of common stock reserved under the Plans for issuance under future share-based payment arrangements.
	The following table details total stock-based compensation expense for the years ended December 31, 2014, 2013 and 2012, included in the consolidated statements of income:
		2014				2013			2012
	Costs of sales	$	1,648,311			$	601,377		$	459,996
	Operating expenses	2,523,863				1,097,751			804,783
	Pre-tax stock-based compensation expense	4,172,174				1,699,128			1,264,779
	Less: income tax effect	(1,627,148		)		(662,660		)	(493,264		)
	Net (after tax) stock-based compensation expense	2,545,026				1,036,468			771,515
	Cash flows resulting from excess or deficient tax benefits are required to be classified as a part of cash flows from financing activities. Excess tax benefits are realized tax benefits from tax deductions for the vested portion of restricted share awards that are in excess of the deferred tax asset attributable to stock compensation costs for such restricted share awards. Conversely, deficient tax benefits are realized tax benefits from tax deductions for the vested portion of restricted share awards that are less than the deferred tax asset attributable to stock compensation costs for such restricted share awards. As a result, excess (deficient) tax benefits of $26,755, $21,813 and $(96,934) have been classified as financing cash inflows (outflows) for the years ended December 31, 2014, 2013 and 2012, respectively. In addition to tax benefits related to the vested portion of restricted share awards, the Company also pays dividends on unvested restricted stock which resulted in excess tax benefits of $140,571, $74,939 and $98,163 for the years ended December 31, 2014, 2013 and 2012, respectively, which are classified as cash inflows from financing activities.
	Restricted Stock
	The Company grants restricted stock to executive officers, certain key employees and non-employee directors under the Plans with the fair value of the awards representing the fair value of the common stock on the date the restricted stock is granted. Shares of restricted stock generally vest in equal annual installments over the applicable vesting period, which ranges from one to five years. The Company records expenses for these grants on a straight-line basis over the applicable vesting periods.
	A summary of restricted stock activity under the Plans during the years ended December 31, 2014, 2013 and 2012 is as follows:
		Shares			Weighted-Average
					Grant-Date
					Fair Value
	Nonvested stock outstanding at January 1, 2012	100,346			$	60.79

	Forfeited	—			—
	Nonvested stock outstanding at December 31, 2014	160,216			$	59.14
	As of December 31, 2014, there was $7,267,059 of total unrecognized compensation cost related to non-vested restricted stock arrangements granted under the Plans, which is expected to be recognized over a weighted-average period of 2.25 years.
	Performance Share Awards
	In 2014, the Company began to grant performance share awards to executive officers and certain key employees under the 2014 Incentive Plan. The number of shares of common stock earned and issuable under the award is determined at the end of each performance period, based on the Company's achievement of performance goals predetermined by the Compensation Committee of the Board of Directors at the time of grant. If certain levels of the performance criteria are met, the award results in the issuance of shares of restricted stock corresponding to such level, which shares are then subject to time-based vesting pursuant to which the shares of restricted stock vest in equal annual installments over the applicable vesting period, which is generally three years for restricted stock issued pursuant to performance share awards.
	In the event that the Company's financial performance meets the predetermined target for the performance criteria, the Company will issue each award recipient the number of restricted shares equal to the target award specified in the individual's underlying performance share award agreement. In the event the financial results of the Company exceed the predetermined target, additional shares up to the maximum award may be issued. In the event the financial results of the Company fall below the predetermined target, a reduced number of shares may be issued. If the financial results of the Company fall below the threshold performance level, no shares will be issued.
	The recipients of performance share awards do not receive dividends or possess voting rights during the performance period and, accordingly, the fair value of the performance share awards is the quoted market value of the Company stock on the grant date less the present value of the expected dividends not received during the relevant period. Expense is recognized using the accelerated attribution (graded vesting) method over the period beginning on the date the Company determines that it is probable that the performance criteria will be achieved and ending on the last day of the vesting period for the restricted stock issued in satisfaction of such awards. In the event the Company determines it is no longer probable that the minimum performance level will be achieved, all previously recognized compensation expense related to the applicable awards is reversed in the period such a determination is made.
	A summary of performance share award activity under the 2014 Incentive Plan for the year ended December 31, 2014 is as follows, based on the target award amounts set forth in the performance share award agreements:
		Shares			Weighted-Average
					Grant-Date

	Granted	46,541			60.28
	Performance share awards converted to restricted stock	—			—
	Performance share awards outstanding at December 31, 2014	46,541			$	60.28
	As of December 31, 2014, there was $2,108,759 of total unrecognized compensation cost related to performance share awards granted under the Plans, which is expected to be recognized over a weighted-average period of 2.25 years.

Risks and Uncertainties [Abstract]
Concentration of Credit Risk	CONCENTRATION OF CREDIT RISK
	Financial instruments, which potentially subject the Company to concentration of credit risk, consist principally of temporary cash investments and trade receivables. The Company places its temporary cash investments with credit-worthy, high-quality financial institutions.
	The Company’s customer base is concentrated in the healthcare industry. Customers are located throughout the United States. The Company requires no collateral or other security to support customer accounts receivable. An allowance for doubtful accounts has been established for potential credit losses based on historical collection experience.
	The Company maintains its cash and cash equivalents in bank deposit accounts, which, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk on cash and cash equivalents.

Receivables [Abstract]
Financing Receivables	FINANCING RECEIVABLES
	Short-Term Payment Plans
	The Company has sold information and patient care systems to certain healthcare providers under Second Generation Meaningful Use Installment Plans (see below) with maximum contractual terms of three years and expected terms of less than one year and other arrangements requiring fixed monthly payments over terms ranging from 3 to 12 months ("Fixed Periodic Payment Plans"). These receivables, collectively referred to as short-term payment plans and included in the current portion of financing receivables, were comprised of the following on December 31, 2014 and 2013:
		2014			2013
	Second Generation Meaningful Use Installment Plans, gross	$	15,554,900		$	23,901,435
	Fixed Periodic Payment Plans, gross	2,239,817			1,416,335
	Short-term payment plans, gross	$	17,794,717		$	25,317,770
	Less: allowance for losses	(889,736		)	(1,265,889		)
	Less: unearned income	—			—
	Short-term payment plans, net	$	16,904,981		$	24,051,881
	The significant decrease in amounts due under short-term payment plans from December 31, 2013 to December 31, 2014 is due to those factors described under the caption "Second Generation Meaningful Use Installment Plans" below.
	Sales-Type Leases
	Additionally, the Company leases its information and patient care systems to certain healthcare providers under sales-type leases expiring in various years through 2017. These receivables typically have terms from two to five years, bear interest at various rates, and are usually collateralized by a security interest in the underlying assets. Since the Company has a history of successfully collecting amounts due under the original payment terms of these extended payment arrangements without making any concessions to its customers, the Company satisfies the requirement for revenue recognition. The Company’s history with these types of extended payment term arrangements supports management’s assertion that revenues are fixed and determinable and collection is probable.
	The components of these lease receivables were as follows on December 31:
		2014			2013
	Sales-type leases, gross	$	2,152,218		$	2,081,512

	Net lease receivables	$	2,088,271
	Credit Quality of Financing Receivables and Allowance for Credit Losses
	The following table is a roll-forward of the allowance for financing credit losses for the years ended December 31, 2014 and 2013:
		Beginning			Provision			Charge-offs			Recoveries		Ending
		Balance											Balance
	31-Dec-14	$	1,365,190		$	(349,280	)	$	(14,724	)	$	—	$	1,001,186
	31-Dec-13	$	662,315		$	1,309,160		$	(606,285	)	$	—	$	1,365,190
	The Company’s financing receivables are comprised of a single portfolio segment, as the balances are all derived from short-term payment plan arrangements and sales-type leasing arrangements within our target market of rural and community hospitals. The Company evaluates the credit quality of its financing receivables based on a combination of factors, including, but not limited to, customer collection experience, economic conditions, the customer’s financial condition, and known risk characteristics impacting the respective customer base of rural and community hospitals, the most notable of which relate to enacted and potential changes in Medicare and Medicaid reimbursement rates as rural and community hospitals typically generate a significant portion of their revenues and related cash flows from beneficiaries of these programs. In addition to specific account identification, the Company utilizes historical collection experience to establish the allowance for credit losses. Financing receivables are written off only after the Company has exhausted all collection efforts. The Company has been successful in collecting its financing receivables and considers the credit quality of such arrangements to be good, especially as the underlying assets act as collateral for the receivables.
	Customer payments are considered past due if a scheduled payment is not received within contractually agreed upon terms. To facilitate customer collection and credit monitoring efforts, financing receivable amounts are invoiced and reclassified to trade accounts receivable when they become due, with all invoiced amounts placed on nonaccrual status. As a result, all past due amounts related to the Company’s financing receivables are included in trade accounts receivable in the accompanying consolidated balance sheets. The following is an analysis of the age of financing receivables amounts (excluding short-term payment plans) that have been reclassified to trade accounts receivable and were past due as of December 31, 2014 and December 31, 2013:
		1 to 90 Days			91 to 180 Days			181 + Days			Total
		Past Due			Past Due			Past Due			Past Due
	31-Dec-14	$	161,160		$	16,978		$	10,072		$	188,210
	31-Dec-13	$	511,792		$	85,738		$	57,429		$	654,959
	From time to time, the Company may agree to alternative payment terms outside of the terms of the original financing receivable agreement due to customer difficulties in achieving the original terms. In general, such alternative payment arrangements do not result in a re-aging of the related receivables. Rather, payments pursuant to any alternative payment arrangements are applied to the already outstanding invoices beginning with the oldest outstanding invoices as the payments are received.
	Because amounts are reclassified to trade accounts receivable when they become due, there are no past due amounts included within the financing receivables or the financing receivables, current portion, net amounts in the accompanying consolidated balance sheets.
	The Company utilizes an aging of trade accounts receivable as the primary credit quality indicator for its financing receivables, which is facilitated by the reclassification of customer payment amounts to trade accounts receivable when they become due. The table below categorizes customer financing receivable balances (excluding short term payment plans), none of which are considered past due, based on the age of the oldest payment outstanding that has been reclassified to trade accounts receivable:
		31-Dec-14			31-Dec-13
	Customer balances with amounts reclassified to trade accounts receivable that are:
	1 to 90 Days Past Due	$	361,303		$	1,322,823
	91 to 180 Days Past Due	349,721			368,424
	181+ Days Past Due	27,500			37,537
	Total customer balances with past due amounts reclassified to trade accounts receivable	$	738,524		$	1,728,784
	Total customer balances with no past due amounts reclassified to trade accounts receivable	1,349,747			257,229
	Total financing receivables with contractual maturities of one year or less	17,794,717			25,317,770
	Less allowance for losses	(1,001,186		)	(1,365,190		)
	Total financing receivables	$	18,881,802		$	25,938,593
	First Generation Meaningful Use Installment Plans
	During 2012, the Company entered into multiple customer license agreements with payment terms requiring the customer to remit to the Company incentive payments (not to exceed the remaining balance of the contract price) received under the American Recovery and Reinvestment Act of 2009 (the "ARRA") for adoption of qualifying electronic health records ("EHRs"), with only nominal payment amounts required until the customer’s receipt of such incentive payments ("First Generation Meaningful Use Installment Plans"). If no such incentive payments are received by the customer or if such payments are not sufficient to pay the remaining balance under the arrangement, payments continue at contracted nominal amounts until the balance of the contract price is paid in full. Because of the significant difference in the underlying economics of these arrangements compared to our historical financing receivables, management determined that these arrangements were not comparable to historical arrangements. In accordance with the Software topic and Revenue Recognition subtopic of the Codification, the Company recognizes revenue related to these arrangements as the amounts become due. Anticipated future cash flows from these First Generation Meaningful Use Installment Plans are excluded from the Company’s financing receivables and deferred revenue in the accompanying consolidated balance sheets. Direct, incremental costs in the amount of $40,170, included as a component of prepaid expenses and other in the accompanying consolidated balance sheets, have been capitalized as of December 31, 2014 related to these arrangements.
	Second Generation Meaningful Use Installment Plans
	Beginning in the fourth quarter of 2012, we ceased offering First Generation Meaningful Use Installment Plans to our customers, opting instead for license agreements with payment terms that provide us with greater visibility into and control over the customer’s meaningful use attestation process and significantly reducing the maximum timeframe over which customers must satisfy their full payment obligations in purchasing our system (“Second Generation Meaningful Use Installment Plans”). As the overall payment period durations of the Second Generation Meaningful Use Installment Plans are consistent with that of our historical system sale financing arrangements, revenues under the Second Generation Meaningful Use Installment Plans are recognized upon installation of our EHR solution. Although these arrangements provide for a maximum payment term of three years, management has determined the expected term for these arrangements to be less than one year due to (a) historical collection patterns of required EHR incentive payment amounts and (b) the estimated significance of those amounts, the receipt of which is expected to result in minimal or no remaining balance for the related arrangements. As a result, all related amounts are included as a component of financing receivables, current portion, net in the accompanying consolidated balance sheets and as a component of short-term payment plans within this Note 10.
	Second Generation Meaningful Use Installment Plans comprised nearly all of our new system installations during the year ended December 31, 2013, compared to approximately one-third of our new system installations during the year ended December 31, 2014. This decreased utilization of Second Generation Meaningful Use Installment Plans, coupled with payments received under such arrangements during the year ended December 31, 2014, has resulted in the overall significant decrease in our financing receivables balance related to short-term payment plans from December 31, 2013 to December 31, 2014.

Benefit Plans	BENEFIT PLANS
	In January 1994, the Company adopted the CPSI 401(k) Retirement Plan that covers all eligible employees of the Company who have completed one year of service. The plan allows eligible employees to contribute up to 60% of their pre-tax earnings up to the statutory limit prescribed by the Internal Revenue Service. The Company matches a discretionary amount determined by the Board of Directors. The Company contributed approximately $2,183,000, $2,020,000 and $1,749,000 to the plan for the years ended December 31, 2014, 2013 and 2012, respectively.
	The Company provides certain health and medical benefits to eligible employees, their spouses and dependents pursuant to a benefit plan funded by the Company. Each participating employee contributes to the Company’s costs associated with such benefit plan. The Company’s obligation to fund this benefit plan and pay for these benefits is limited through the Company’s purchase of an insurance policy from a third-party insurer. The amount established as a reserve is intended to recognize the Company’s estimated obligations with respect to its payment of claims and claims incurred but not yet reported under the benefit plan. Management believes that the recorded liability for medical self-insurance at December 31, 2014 and 2013 is adequate to cover the losses and claims incurred, but these reserves are based on estimates and the amount ultimately paid may be more or less than such estimates.

Fair Value Disclosures [Abstract]
Fair Value	FAIR VALUE
	FASB Codification topic, Fair Value Measurements and Disclosures, establishes a framework for measuring fair value and expands financial statement disclosures about fair value measurements. Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The Codification topic does not require any new fair value measurements, but rather applies to all other accounting pronouncements that require or permit fair value measurements. The Codification topic requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:
	Level 1: Quoted market prices in active markets for identical assets or liabilities.
	Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.
	Level 3: Unobservable inputs that are not corroborated by market data.
	The fair values of the Company’s available-for-sale securities are based on matrix pricing for the periods ended December 31, 2014 and 2013, which uses observable market-based inputs (such as benchmark yields) in addition to quoted prices in active markets to derive fair values. As a result, these inputs are classified as Level 2 within the fair value hierarchy. We generally apply fair value techniques on a non-recurring basis associated with (1) valuing potential impairment loss related to financing receivables accounted for pursuant to Codification topic, Leases, and (2) valuing potential impairment loss related to long-lived assets accounted for pursuant to Codification topic, Property, Plant and Equipment, when events or circumstances indicate a possible impairment.
	The following table summarizes the carrying amounts and fair values of certain assets and liabilities at December 31, 2014 and December 31, 2013:

	Declaration of Dividends
	On January 29, 2015, the Company announced a dividend for the first quarter of 2015 in the amount of $0.64 per share. The dividend was paid on February 27, 2015 to stockholders of record as of the close of business on February 12, 2015.
	Issuance of Restricted Stock
	On February 5, 2015, the Compensation Committee of the Board of Directors (the "Committee") approved the grant of a total of 6,750 shares of restricted stock, effective February 5, 2015, to certain of the non-employee directors of the Company under the Company’s 2012 Restricted Stock Plan for Non-Employee Directors. The grant date fair value was $51.85 per share. Under the terms of the restricted stock award agreements with the non-employee directors, the shares of restricted stock are scheduled to vest on the first anniversary of the date of grant, assuming that the recipient of the grant continues to serve as a director of the Company on the vesting date. Compensation expense for this grant will be recognized on a straight-line basis over one year.
	Additionally, on February 5, 2015, the Committee approved the grant of a total of 54,100 shares of restricted stock, effective February 5, 2015, to executive officers and certain key employees under the 2014 Incentive Plan. The grant date fair value was $51.85 per share. Under the terms of the restricted stock award agreements with the executive officers and certain key employees, the shares of restricted stock are scheduled to vest in three equal annual installments commencing on the first anniversary of the grant date, assuming that the recipient of the award continues to serve as an employee of the Company on each applicable vesting date. Compensation expense for this grant will be recognized on a straight-line basis over three years.
	Finally, on February 5, 2015, the Committee approved the grant of a total of 45,843 shares of restricted stock, effective February 5, 2015, to executive officers and certain key employees related to performance share awards issued during 2014 under the 2014 Incentive Plan as a result of the achievement of performance goals predetermined by the Committee. Achievement of these performance goals during 2014 resulted in a grant of restricted stock equal to 98.5% of the total target award amount of 46,541 shares. The grant date fair value of the performance share awards was $60.28 per share. Under the terms of the restricted stock award agreements with the executive officers and certain key employees, the shares of restricted stock are scheduled to vest in three equal annual installments commencing on the first anniversary of the Vesting Determination Date, defined by the Committee as February 5, 2015. Compensation expense for this grant is being recognized using the accelerated attribution (graded vesting) method over the period beginning on May 15, 2014, the date the Company determined that it was probable that the performance criteria would be achieved, and ending on the last day of the vesting period for the restricted stock issued in satisfaction of the performance share awards.
	Issuance of Performance Share Awards
	On February 5, 2015, the Committee approved the grant of performance share awards to executive offices and certain key employees with a total target award of 52,364 shares of common stock. The number of shares of common stock earned and issuable under the award will be determined at the end of the performance period, based on the Company's achievement of performance goals predetermined by the Committee at the time of grant. If certain levels of the performance criteria are met, the award results in the issuance of shares of restricted stock corresponding to such level, which shares are then subject to time-based vesting pursuant to which the shares of restricted stock vest in equal annual installments over the applicable vesting period, which is generally three years for restricted stock issued pursuant to performance share awards.
	In the event that the Company's financial performance meets the predetermined target for the performance criteria, the Company will issue each award recipient the number of restricted shares equal to the target award specified in the individual's underlying performance share award agreement. In the event the financial results of the Company exceed the predetermined target, additional shares up to the maximum award of 78,549 shares may be issued. In the event the financial results of the Company fall below the predetermined target, a reduced number of shares may be issued. If the financial results of the Company fall below the threshold performance level, no shares will be issued.
	The grant date fair value of the performance share awards was $49.29 per share. Expense will be recognized using the accelerated attribution (graded vesting) method over the period beginning on the date the Company determines that it is probable that the performance criteria will be achieved and ending on the last day of the vesting period for the restricted stock issued in satisfaction of such awards. In the event the Company determines it is no longer probable that the minimum performance level will be achieved, all previously recognized compensation expense related to the applicable awards will be reversed in the period such a determination is made.

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation
	The consolidated financial statements of CPSI include the accounts of TruBridge, a wholly-owned subsidiary of CPSI. All significant intercompany balances and transactions have been eliminated.
Cash and Cash Equivalents	Cash and Cash Equivalents
	Cash and cash equivalents can include time deposits and certificates of deposit with original maturities of three months or less that are highly liquid and readily convertible to a known amount of cash. These assets are stated at cost, which approximates market value, due to their short duration or liquid nature.
Investments	Investments
	The Company accounts for investments in accordance with FASB Codification topic, Investments – Debt and Equity Securities. Accordingly, investments are classified as available-for-sale securities and are reported at fair value, with unrealized gains and losses excluded from earnings and reported in a separate component of stockholders’ equity. The Company’s management determines the appropriate classifications of investments in fixed maturity securities at the time of acquisition and re-evaluates the classifications at each balance sheet date. An average cost method is used for purposes of determining the cost of investments sold.
Income Taxes	Income Taxes
	We account for income taxes in accordance with FASB Codification topic – Income Taxes. Under this topic, deferred income taxes are determined utilizing the asset and liability approach. This method gives consideration to the future tax consequences associated with differences between financial accounting and tax bases of assets and liabilities. The effect on the deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We recognize interest and penalties accrued related to unrecognized tax benefits in the consolidated statements of income as a component of the provision for income taxes.
	We also make a provision for uncertain income tax positions in accordance with the Income Taxes Codification topic. These provisions require that a tax position taken in a tax return be recognized in the financial statements when it is more likely than not (i.e., a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon settlement. The topic also requires that changes in judgment that result in subsequent recognition, derecognition, or change in a measurement date of a tax position taken in a prior annual period (including any related interest and penalties) be recognized as a discrete item in the interim period in which the change occurs.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts
	Trade accounts receivable are stated at the amount the Company expects to collect and do not bear interest. The Company establishes a general allowance for doubtful accounts based on collections history. In the case of a bankruptcy filing or other similar event indicating the collectability of specific customer accounts is no longer probable, a specific reserve for bad debt may be recorded to reduce the related receivable to the amount expected to be recovered.
Financing Receivables	Financing Receivables
	Financing receivables are comprised of short-term payment plans and sales-type leases. Short-term payment plans are stated at the amount the Company expects to collect and do not bear interest. Sales-type leases are initially recorded at the present value of the related minimum lease payments, computed at the interest rate implicit in the lease, and are presented net of unearned income. Unearned income is amortized over the lease term to produce a constant periodic rate of return on the net investment in the lease (the interest method).
	An allowance for credit losses has been established for our financing receivables based on the historical level of customer defaults under such arrangements. In the case of a bankruptcy filing or other similar event indicating the collectability of specific customer accounts is no longer probable, a specific reserve may be recorded to reduce the related receivable to the amount expected to be recovered. Customer payments are considered past due if a scheduled payment is not received within contractually agreed upon terms, with amounts reclassified to accounts receivable when they become due. As a result, we evaluate the credit quality of our financing receivables on an ongoing basis utilizing an aging of receivables and write-offs, customer collection experience, the customer’s financial condition and known risk characteristics impacting the respective customer base, as well as existing economic conditions, to determine if any further allowance is necessary. Amounts are specifically charged off once all available means of collection have been exhausted.
Inventories	Inventories
	Inventories are stated at lower of cost or market using the average cost method. The Company’s inventories are comprised of computer equipment, forms and supplies. For cash flow presentation, inventory used by the Company and capitalized as property and equipment is shown as a change in inventory.
Property and Equipment	Property and Equipment
	Property and equipment is recorded at cost, less accumulated depreciation. Additions and improvements to property and equipment that materially increase productive capacity or extend the life of an asset are capitalized. Maintenance, repairs and minor renewals are expensed as incurred. Upon retirement or other disposition of such assets, the related costs and accumulated depreciation are removed from the respective accounts and any resulting gain or loss is included in the results of operations.
	Depreciation expense is computed using the straight-line method over the asset’s useful life, which is generally 5 years for computer equipment, furniture, and fixtures and 30 years for buildings. Leasehold improvements are depreciated over the shorter of the asset’s useful life or the remaining lease term. The Company reviews for the possible impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Depreciation expense is reported in the consolidated statements of income as a component of support and maintenance costs and operating expenses.
Deferred Revenue	Deferred Revenue
	Deferred revenue represents amounts received from customers under licensing agreements and implementation fees for which the revenue recognition process has not been completed.
Multiple-Deliverable Revenue Arrangements	Revenue Recognition
	The Company recognizes revenue in accordance with accounting principles generally accepted in the United States of America ("US GAAP"), principally those required by the Software topic and Revenue Recognition subtopic of the Codification and those prescribed by the Securities and Exchange Commission (the "SEC").
	The Company's revenue is generated from three sources:
	•	System Sales - the sale of information systems, which includes perpetual software licenses, conversion, installation and training services, hardware and peripherals;
	•	Support and Maintenance - the provision of system support services, which includes software application support, hardware maintenance, continuing education, "Software as a Service" (or "SaaS") services, and forms and supplies; and
	•	Business Management, Consulting and Managed IT Services - the provision of business management services, which includes electronic billing, statement processing, payroll processing, accounts receivable management, contract management and insurance services, as well as Internet service provider ("ISP") services and consulting and managed IT services (collectively, "other professional IT services").
	System Sales, Software Application Support and Hardware Maintenance
	The Company enters into contractual obligations to sell perpetual software licenses, conversion, installation and training services, hardware and software application support and hardware maintenance services. On average, the Company is able to complete a system installation in three to four weeks. The methods employed by the Company to recognize revenue, which are discussed by element below, achieve results materially consistent with the provisions of Accounting Standards Update ("ASU") 2009-13, Multiple-Deliverable Revenue Arrangements, due to the relatively short period during which there are multiple undelivered elements, the relatively small amount of non-software related elements in the system sale arrangements, and the limited number of contracts in-process at the end of each reporting period. The Company recognizes revenue on the elements noted above as follows:
	•	Perpetual software licenses and conversion, installation and training services – The selling price of perpetual software licenses and conversion, installation and training services is based on management’s best estimate of selling price. In determining management’s best estimate of selling price, we consider the following: (1) competitor pricing, (2) supply and demand of installation staff, (3) overall economic conditions, and (4) our pricing practices as they relate to discounts. With the exception of certain arrangements with extended payment terms that were entered into in 2012 and that are not comparable to our historical or current arrangements (see Note 10), the method of recognizing revenue for the perpetual license of the associated modules included in the arrangement, and the related conversion, installation and training services over the term the services are performed, is on a module by module basis as the related perpetual licenses are delivered and the respective conversion, installation and training for each specific module is completed, as this is representative of the pattern of provision of these services.
	•	Hardware – We recognize revenue for hardware upon shipment. The selling price of hardware is based on management’s best estimate of selling price, which consists of cost plus a targeted margin.
	•	Software application support and hardware maintenance – We have established vendor-specific objective evidence ("VSOE") of the fair value of our software application support and hardware maintenance services by reference to the price our customers are required to pay for the services when sold separately via renewals. Support and maintenance revenue is recognized on a straight-line basis over the term of the maintenance contract, which is generally three to five years.
	SaaS, ISP and Other Professional IT Services
	The Company accounts for SaaS arrangements in accordance with the requirements of the Hosting Arrangement section under the Software topic and Revenue Recognition subtopic of the Codification. The Codification states that the software elements of SaaS services should not be accounted for as a hosting arrangement "if the customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty and it is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software." Each SaaS contract entered into by the Company includes a system purchase and buyout clause, and this clause specifies the total amount of the system buyout. In addition, a clause is included in the contract which states that should the system be bought out by the customer, the customer would be required to enter into a general support agreement (for post-contract support services) for the remainder of the original SaaS term. Accordingly, the Company has concluded that SaaS customers do not have the right to take possession of the system without significant penalty (i.e., the purchase price of the system), resulting in the determination that these contracts are service contracts for which revenue is recognized when the services are performed.
	The Company will occasionally provide ISP and other professional IT services. Depending on the nature of the services provided, these services may be considered software elements or non-software elements. The selling price of services considered to be software elements is based on VSOE of the fair value of the services by reference to the price our customers are required to pay for the services when sold separately. The selling price of services considered to be non-software elements is based on third-party evidence of selling price of similar services. Revenue from these elements are recognized as the services are performed.
	Business Management Services
	Business management services consist of electronic billing, statement processing, payroll processing, accounts receivable management, contract management and insurance services. While business management service arrangements are contracts separate from the system sale and support and maintenance contracts, these contracts are often executed within a short time frame of each other. The amount of the total arrangement allocated to these services is based on VSOE of fair value by reference to the rate at which our customers renew as well as the rate at which the services are sold to customers when the business management services agreement is not executed within a short time frame of the system sale and support and maintenance contracts. If VSOE of fair value does not exist for these services, we allocate arrangement consideration based on third-party evidence ("TPE") of selling price or, if neither VSOE nor TPE is available, estimated selling price. Because the pricing is transaction based (per unit pricing), customers are billed and revenue recognized as services are performed based on transaction levels.
Stock-Based Compensation	Stock-Based Compensation
	The Company accounts for stock-based compensation according to the provisions of FASB Codification topic, Compensation – Stock Compensation, which establishes accounting for stock-based awards exchanged for employee services. Accordingly, stock-based compensation cost is measured at the grant date based on the fair value of the award, and is recognized as an expense over the employee’s or non-employee director’s requisite service period.
Research and Development Costs	Research and Development Costs
	Research and development costs are expensed as incurred.
	Research and development costs are included in costs of support and maintenance in the accompanying consolidated statements of income.
Advertising	Advertising
	Advertising costs are expensed as incurred.
Shipping and Handling Costs	Shipping and Handling Costs
	Shipping and handling costs are expensed as incurred and included in general and administrative expenses and costs of business management, consulting and managed IT services.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the financial statements, and the reported revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Accounting Standards Adopted in the Current Year	New Accounting Standards Adopted in 2014
	There were no new standards required to be adopted during the year ended December 31, 2014 that had or will have a material impact on our financial statements.
New Accounting Standards Yet to be Adopted	New Accounting Standards Yet to be Adopted
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, to clarify the principles for recognizing revenue and to develop a common revenue standard for US GAAP and International Financial Reporting Standards. The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes the most current revenue recognition guidance. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2016, which is effective for the Company as of the first quarter of our fiscal year ending December 31, 2017. The Company is currently evaluating the impact that the implementation of this standard will have on its financial statements.
Net Income Per Share	NET INCOME PER SHARE
	The Company presents basic and diluted earnings per share ("EPS") data for its common stock. Basic EPS is calculated by dividing the net income attributable to stockholders of the Company by the weighted average number of shares of common stock outstanding during the period. Diluted EPS is determined by adjusting the net income attributable to stockholders of the Company and the weighted average number of shares of common stock outstanding during the period for the effects of all dilutive potential common shares, including awards under stock-based compensation arrangements.
	The Company's unvested restricted stock awards (see Note 8) are considered participating securities under FASB Codification topic, Earnings Per Share, because they entitle holders to non-forfeitable rights to dividends until the awards vest or are forfeited. When a company has a security that qualifies as a "participating security," the Codification requires the use of the two-class method when computing basic EPS. The two-class method is an earnings allocation formula that determines EPS for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. In determining the amount of net income to allocate to common stockholders, income is allocated to both common stock and participating securities based on their respective weighted average shares outstanding for the period, with net income attributable to common stockholders ultimately equaling net income less net income attributable to participating securities. Diluted EPS for the Company's common stock is computed using the more dilutive of the two-class method or the treasury stock method.
