(11)	Retirement and Other Benefit Plans

Roper maintains eleven defined contribution retirement plans under the provisions of Section 401(k) of the IRC covering substantially all U.S. employees not subject to collective bargaining agreements. Roper partially matches employee contributions. Costs related to these plans were $16.4 million, $15.2 million and $14.0 million for 2012, 2011 and 2010, respectively.

Roper also maintains various defined benefit retirement plans covering employees of non-U.S. and certain U.S. subsidiaries and a plan that supplements certain employees for the contribution ceiling applicable to the Section 401(k) plans. The costs and accumulated benefit obligations associated with each of these plans were not material.

Contingencies [Abstract]

Contingencies [Text Block]

(13)	Contingencies

Roper, in the ordinary course of business, is the subject of, or a party to, various pending or threatened legal actions, including product liability and employment practices. It is vigorously contesting all lawsuits that, in general, are based upon claims of the kind that have been customary over the past several years. After analyzing the Company's contingent liabilities on a gross basis and, based upon past experience with resolution of its product liability and employment practices claims and the limits of the primary, excess, and umbrella liability insurance coverages that are available with respect to pending claims, management believes that adequate provision has been made to cover any potential liability not covered by insurance, and that the ultimate liability, if any, arising from these actions should not have a material adverse effect on the consolidated financial position, results of operations or cash flows of Roper.

Over recent years there has been a significant increase in certain U.S. states in asbestos-related litigation claims against numerous industrial companies. Roper or its subsidiaries have been named defendants in some such cases. No significant resources have been required by Roper to respond to these cases and Roper believes it has valid defenses to such claims and, if required, intends to defend them vigorously. Given the state of these claims it is not possible to determine the potential liability, if any.

Roper's rent expense was $26.8 million, $29.7 million and $29.1 million for 2012, 2011 and 2010, respectively. Roper's future minimum property lease commitments are as follows (in millions):

2013	$	23.4
2014		17.4
2015		14.3
2016		12.5
2017		7.4
Thereafter		3.0
Total	$	78.0

A summary of the Company's warranty accrual activity is presented below (in thousands):

	2012			2011			2010
Balance, beginning of year	$	8,147		$	7,038		$	7,341

Summary of Accounting Policies [Abstract]

Summary of Accounting Policies [Text Block]

(1)	Summary of Accounting Policies

Basis of Presentation - These financial statements present consolidated information for Roper Industries, Inc. and its subsidiaries ("Roper" or the "Company"). All significant intercompany accounts and transactions have been eliminated.

Nature of the Business - Roper is a diversified growth company that designs, manufactures and distributes energy systems and controls, medical and scientific imaging products and software, industrial technology products and radio frequency products, services and application software. Roper markets these products and services to a broad range of markets, including radio frequency applications, medical, water, energy, research, education, software-as-a-service ("SaaS")-based information networks, security and other niche markets.

Accounts Receivable - Accounts receivable were stated net of an allowance for doubtful accounts and sales allowances of $16.0 million and $10.6 million at December 31, 2012 and 2011, respectively. Outstanding accounts receivable balances are reviewed periodically, and allowances are provided at such time that management believes it is probable that an account receivable is uncollectible. The returns and other sales credit allowance is an estimate of customer returns, exchanges, discounts or other forms of anticipated concessions and is treated as a reduction in revenue.

Cash and Cash Equivalents - Roper considers highly liquid financial instruments with remaining maturities at acquisition of three months or less to be cash equivalents. Roper had no cash equivalents at December 31, 2012 and $136 million at December 31, 2011.

Contingencies - Management continually assesses the probability of any adverse judgments or outcomes to its potential contingencies. Disclosure of the contingency is made if there is at least a reasonable possibility that a loss or an additional loss may have been incurred. In the assessment of contingencies as of December 31, 2012, management concluded that no accrual was necessary and that there were no matters for which there was a reasonable possibility of a material loss.

Earnings per Share - Basic earnings per share were calculated using net earnings and the weighted-average number of shares of common stock outstanding during the respective year. Diluted earnings per share were calculated using net earnings and the weighted-average number of shares of common stock and potential common stock outstanding during the respective year. Potentially dilutive common stock consisted of stock options and the premium over the conversion price on Roper's senior subordinated convertible notes based upon the trading price of the Company's common stock. The effects of potential common stock were determined using the treasury stock method (in thousands):

	Years ended December 31,
	2012	2011	2010
Basic weighted-average shares outstanding	97,702	95,959	94,242
Effect of potential common stock:
Common stock awards	1,040	1,213	1,009
Senior subordinated convertible notes	816	1,214	1,402
Diluted weighted-average shares outstanding	99,558	98,386	96,653

As of and for the years ended December 31, 2012, 2011 and 2010, there were 547,591, 760,000 and 1,143,350 outstanding stock options, respectively, that were not included in the determination of diluted earnings per share because doing so would have been antidilutive.

Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Foreign Currency Translation and Transactions - Assets and liabilities of subsidiaries whose functional currency is not the U.S. dollar were translated at the exchange rate in effect at the balance sheet date, and revenues and expenses were translated at average exchange rates for the period in which those entities were included in Roper's financial results. Translation adjustments are reflected as a component of other comprehensive income. Foreign currency transaction gains and losses are recorded in the income statement as other income/(expense). The gain or loss included in pre-tax income was a net loss of $2.8 million for the year ended December 31, 2012, a net gain of $6.9 million for the year ended December 31, 2011 and a net loss of $0.9 million for the year ended December 31, 2010.

Goodwill and Other Intangibles - Roper accounts for goodwill in a purchase business combination as the excess of the cost over the fair value of net assets acquired. Business combinations can also result in other intangible assets being recognized. Amortization of intangible assets, if applicable, occurs over their estimated useful lives. Goodwill, which is not amortized, is tested for impairment on an annual basis (or an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value) using a two-step process. The first step of the process utilizes both an income approach (discounted cash flows) and a market approach consisting of a comparable public company earnings multiples methodology to estimate the fair value of a reporting unit. To determine the reasonableness of the estimated fair values, the Company reviews the assumptions to ensure that neither the income approach nor the market approach provides significantly different valuations. If the estimated fair value exceeds the carrying value, no further work is required and no impairment loss is recognized. If the carrying value exceeds the estimated fair value, the goodwill of the reporting unit is potentially impaired and then the second step would be completed in order to measure the impairment loss by calculating the implied fair value of goodwill by deducting the fair value of all tangible and intangible net assets (including unrecognized intangible assets) of the reporting unit from the fair value of the reporting unit. If the implied fair value of goodwill is less than the carrying value of goodwill, a non-cash impairment loss would be recognized.

Key assumptions used in the income and market methodologies are updated when the analysis is performed for each reporting unit. Various assumptions are utilized including forecasted operating results, strategic plans, economic projections, anticipated future cash flows, the weighted-average cost of capital, comparable transactions, market data and earnings multiples. The assumptions that have the most significant effect on the fair value calculations are the anticipated future cash flows, discount rates, and the earnings multiples. While the Company uses reasonable and timely information to prepare its cash flow and discount rate assumptions, actual future cash flows or market conditions could differ significantly resulting in future impairment charges related to recorded goodwill balances.

Total goodwill includes 27 reporting units with individual amounts ranging from zero to $992 million. The Company concluded that the fair value of each of its reporting units was significantly in excess of its carrying value, with no impairment indicated as of December 31, 2012. However, negative industry or economic trends, disruptions to its business, actual results significantly below expected results, unexpected significant changes or planned changes in the use of the assets, divestitures and market capitalization declines may have a negative effect on the fair value of Roper's reporting units.

The following events or circumstances would be considered to determine whether interim testing of goodwill would be required:

·	a significant adverse change in legal factors or in the business climate;

·	an adverse action or assessment by a regulator;

·	unanticipated competition;

·	a loss of key personnel;

·	a more-likely-than-not expectation that a reporting unit or a significant portion of a reporting unit will be sold or otherwise disposed of;

·	the testing for recoverability under the Impairment or Disposal of Long-Lived Assets of a significant asset group within a reporting unit; and

·	recognition of a goodwill impairment loss in the financial statements of a subsidiary that is a component of a reporting unit.

Business combinations can also result in other intangible assets being recognized. Amortization of intangible assets, if applicable, occurs over their estimated useful lives. Trade names are determined to have an indefinite useful economic life and are not amortized, but separately tested for impairment during the fourth quarter of the fiscal year or on an interim basis if an event occurs that indicates the fair value is more likely than not below the carrying value. Roper conducts these reviews for all of its reporting units using the relief-from-royalty method, which management believes to be an acceptable methodology due to its common use by valuations specialists in determining the fair value of intangible assets. This methodology assumes that, in lieu of ownership, a third party would be willing to pay a royalty in order to exploit the related benefits of these assets. The fair value of each trade name is determined by applying a royalty rate to a projection of net sales discounted using a risk adjusted rate of capital. Each royalty rate is determined based on the profitability of the reporting unit to which it relates and observed market royalty rates. Sales growth rates are determined after considering current and future economic conditions, recent sales trends, discussions with customers, planned timing of new product launches or other variables.

The assessment of fair value for impairment purposes requires significant judgments to be made by management. Although forecasts are based on assumptions that are considered reasonable by management and consistent with the plans and estimates management is using to operate the underlying businesses, there is significant judgment in determining the expected results attributable to the reporting units. Changes in estimates or the application of alternative assumptions could produce significantly different results. No impairment resulted from the annual reviews performed in 2012.

Roper evaluates whether there has been an impairment of identifiable intangible assets with definite useful economic lives, or of the remaining life of such assets, when certain indicators of impairment are present. In the event that facts and circumstances indicate that the cost or remaining period of amortization of any asset may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future gross, undiscounted cash flows associated with the asset would be compared to the asset's carrying amount to determine if a write-down to fair value or a revision in the remaining amortization period is required.

Impairment of Long-Lived Assets - The Company determines whether there has been an impairment of long-lived assets, excluding goodwill and identifiable intangible assets that are determined to have indefinite useful economic lives, when certain indicators of impairment are present. In the event that facts and circumstances indicate that the cost or life of any long-lived assets may be impaired, an evaluation of recoverability would be performed. If an evaluation is required, the estimated future gross, undiscounted cash flows associated with the asset would be compared to the asset's carrying amount to determine if a write-down to fair value or revision to remaining life is required. Future adverse changes in market conditions or poor operating results of underlying long-lived assets could result in losses or an inability to recover the carrying value of the long-lived assets that may not be reflected in the assets' current carrying value, thereby possibly requiring an impairment charge or acceleration of depreciation or amortization expense in the future.

Income Taxes - Roper is a U.S.-based multinational company and the calculation of its worldwide provision for income taxes requires analysis of many factors, including income tax systems that vary from country to country, and the United States' treatment of non-U.S. earnings. The Company provides U.S. income taxes for unremitted earnings of foreign subsidiaries that are not considered permanently reinvested overseas. As of December 31, 2012, the approximate amount of earnings of foreign subsidiaries that the Company considers permanently reinvested and for which deferred taxes have not been provided was approximately $1.05 billion. Because of the availability of U.S. foreign tax credits, it is not practicable to determine the U.S. federal income tax liability that would be payable if such earnings were not reinvested indefinitely.

Although it is the Company's intention to permanently reinvest these earnings indefinitely there are certain events that would cause these earnings to become taxable. These events include, but are not limited to, changes in U.S. tax laws, dividends paid between foreign subsidiaries in the absence of Section 954(c)(6) of the Internal Revenue Code ("IRC"), foreign subsidiary guarantees of U.S. parent debt and the liquidation of foreign subsidiaries or actual distributions by foreign subsidiaries into a U.S. affiliate.

Certain assets and liabilities have different bases for financial reporting and income tax purposes. Deferred income taxes have been provided for these differences at the tax rates expected to be paid.

Interest Rate Risk - The Company manages interest rate risk by maintaining a combination of fixed- and variable-rate debt, which may include interest rate swaps to convert fixed-rate debt to variable-rate debt, or to convert variable-rate debt to fixed-rate debt. Interest rate swaps are recorded at fair value in the balance sheet as an asset or liability, and the changes in fair values of both the swap and the hedged item are recorded as interest expense in current earnings.

Inventories - Inventories are valued at the lower of cost or market. Cost is determined using the first-in, first-out method. The Company writes down its inventory for estimated obsolescence or excess inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions.

Other Comprehensive Income - Comprehensive income includes net earnings and all other non-owner sources of changes in a company's net assets.

Product Warranties - The Company sells certain of its products to customers with a product warranty that allows customers to return a defective product during a specified warranty period following the purchase in exchange for a replacement product, repair at no cost to the customer or the issuance of a credit to the customer. The Company accrues its estimated exposure to warranty claims based upon current and historical product sales data, warranty costs incurred and any other related information known to the Company.

Property, Plant and Equipment and Depreciation and Amortization - Property, plant and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided for using principally the straight-line method over the estimated useful lives of the assets as follows:

Buildings	20-30 years
Machinery	8-12 years
Other equipment	3-5 years

Recently Released Accounting Pronouncements - In July 2012, the Financial Accounting Standards Board ("FASB") issued an amendment to accounting rules related to the testing of indefinite-lived intangibles. The new accounting rules permit an entity to first assess qualitative factors to determine if it is more likely than not that an indefinite-lived asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test prescribed under current accounting rules. The guidance is effective for annual and interim tests performed for fiscal years beginning after September 15, 2012. The Company does not expect these rules to have a material effect on its results of operations, financial position or cash flows.

In May 2011, the FASB issued an amendment to accounting and disclosures related to fair value measurement. This amendment results in common principles and requirements for measuring fair value and for disclosing information about fair value measurements in accordance with GAAP and International Financial Reporting Standards. Roper adopted this guidance on January 1, 2012. The guidance did not have a material impact on the Company's results of operations, financial position or cash flows.

In June 2011, the FASB issued an amendment to the disclosure of comprehensive income. This amendment requires the presentation of total comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Roper adopted this guidance on January 1, 2012. The guidance did not have an impact on the Company's results of operations, financial position or cash flows as it is disclosure only in nature.

In September 2011, the FASB issued new accounting rules related to testing goodwill for impairment. The new accounting rules permit an entity to first assess qualitative factors to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform the two-step goodwill impairment test prescribed under current accounting rules. Otherwise, the two-step goodwill impairment test is not required. Roper adopted this guidance on January 1, 2012. The guidance did not have a material effect on its results of operations, financial position or cash flows.

Research and Development - Research and development ("R&D") costs include salaries and benefits, rents, supplies, and other costs related to products under development. Research and development costs are expensed in the period incurred and totaled $125.9 million, $121.7 million and $102.4 million for the years ended December 31, 2012, 2011 and 2010, respectively.

Revenue Recognition - The Company recognizes revenue when all of the following criteria are met:

·	persuasive evidence of an arrangement exists;

·	delivery has occurred or services have been rendered;

·	the seller's price to the buyer is fixed or determinable; and

·	collectibility is reasonably assured.

In addition, the Company recognizes revenue from the sale of product when title and risk of loss pass to the customer, which is generally when product is shipped. The Company recognizes revenue from services when such services are rendered or, if applicable, upon customer acceptance. Revenues under certain relatively long-term and relatively large-value construction projects are recognized under the percentage-of-completion method using the ratio of costs incurred to total estimated costs as the measure of performance. The Company recognized revenues of $145.5 million, $151.5 million and $131.0 million for the years ended December 31, 2012, 2011 and 2010, respectively, using this method. Estimated losses on any projects are recognized as soon as such losses become known.

Capitalized Software - The Company accounts for capitalized software under applicable accounting guidance which, among other provisions, requires capitalization of certain internal-use software costs once certain criteria are met. Overhead, general and administrative and training costs are not capitalized. Capitalized software was $10.9 million and $14.1 million at December 31, 2012 and 2011, respectively.

Stock-Based Compensation - The Company recognizes expense for the grant date fair value of its employee stock option awards on a straight-line basis over the employee's requisite service period (generally the vesting period of the award). The fair value of its option awards is estimated using the Black-Scholes option valuation model and recognizes the expense of all share-based awards. The Company presents the cash flows resulting from the tax benefits arising from tax deductions in excess of the compensation cost recognized for stock award exercises (excess tax benefits) as financing cash flows.

2012 Acquisitions – During the year ended December 31, 2012, Roper completed six business combinations. The results of operations of the acquired companies have been included in Roper's consolidated results since the date of each acquisition.

The largest of the 2012 acquisitions was Sunquest Information Systems, Inc. ("Sunquest"), a leading provider of diagnostic and laboratory software solutions to healthcare providers. Roper acquired 100% of the shares of Sunquest on August 22, 2012, in a $1.416 billion all-cash transaction. The Company acquired Sunquest in order to complement and expand its medical platform. Sunquest is reported in the Medical & Scientific Imaging segment.

The Company expensed transaction costs of $6.5 million related to the acquisition as corporate general and administrative expenses, as incurred.

The following table (in thousands) summarizes the fair values of the assets acquired and liabilities assumed at the date of acquisition. The allocation of the purchase price is considered preliminary pending final intangible asset valuations and tax adjustments.

Concentration of Risk

12 Months Ended

Dec. 31, 2012

Concentration of Risk [Abstract]

Concentration of Risk [Text Block]

(15)	Concentration of Risk

Financial instruments which potentially subject the Company to credit risk consist primarily of cash, cash equivalents and trade receivables.

The Company maintains cash and cash equivalents with various major financial institutions. Cash equivalents include investments in commercial paper of companies with high credit ratings, investments in money market securities and securities backed by the U.S. Government. At times such amounts may exceed the F.D.I.C. limits. The Company limits the amount of credit exposure with any one financial institution and believes that no significant concentration of credit risk exists with respect to cash investments.

Trade receivables subject the Company to the potential for credit risk with customers. To reduce credit risk, the Company performs ongoing evaluations of its customers' financial condition.

- Definition

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.

At December 31, 2012, Roper has approximately $34.3 million of U.S. federal net operating loss carryforwards. If not utilized, these carryforwards will expire in years 2023 through 2032. The net operating loss carryforward increased between 2011 and 2012 primarily because of losses incurred by a U.S. entity that is not a member of the Company's consolidated tax group and whose losses are therefore not available for offset against the taxable income of other members of the group. Also, due to a recent acquisition, the consolidated group has acquired a net operating loss subject to an IRC Section 382 limitation; however, the Company expects to utilize the entire net operating loss prior to expiration. The majority of the state net operating loss carryforward is related to Florida and, if not utilized, will expire in years 2027 through 2030. The Company has smaller net operating losses in various other states. Additionally, Roper has foreign tax credit carryforwards and R&D credit carryforwards. Roper has not recognized a valuation allowance on these attributes since management has determined that it is more likely than not that the results of future operations will generate sufficient taxable income to realize these deferred tax assets.

The Company provides income taxes for unremitted earnings of foreign subsidiaries that are not considered permanently reinvested overseas. As of December 31, 2012, the approximate amount of earnings of foreign subsidiaries that the Company considers permanently reinvested and for which deferred taxes have not been provided was approximately $1.05 billion. Because of the availability of U.S. foreign tax credits, it is not practicable to determine the U.S. federal income tax liability that would be payable if such earnings were not reinvested indefinitely.

Although it is the Company's intention to permanently reinvest these earnings indefinitely there are certain events that would cause these earnings to become taxable. These events include, but are not limited to, change in U.S. tax laws, dividends paid between foreign subsidiaries in the absence of Section 954(c)(6) of the IRC, foreign subsidiary guarantees of U.S. parent debt and the liquidation of foreign subsidiaries or actual distributions by foreign subsidiaries into a U.S. affiliate.

The Company recognizes in the consolidated financial statements only those tax positions determined to be "more likely than not" of being sustained upon examination based on the technical merits of the positions. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in thousands):

	2012			2011			2010
Beginning balance	$	19,556		$	24,765		$	22,922
Additions for tax positions of prior periods		1,371			470			203
Additions for tax positions of the current period		1,541			2,572			3,169
Additions due to acquisitions		9,116			-			3,546
Reductions for tax positions of prior periods		(197	)		(558	)		(565	)
Reductions for tax positions of the current period
Settlements with taxing authorities					(4,043	)		-
Lapse of applicable statute of limitations		(6,522	)		(3,650	)		(4,510	)
Ending balance	$	24,865		$	19,556		$	24,765

The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $21.6 million. Interest and penalties related to unrecognized tax benefits are classified as a component of income tax expense and totaled $1.5 million in 2012. Accrued interest and penalties were $5.0 million at December 31, 2012 and $3.5 million at December 31, 2011. During the next twelve months, the unrecognized tax benefits are expected to decrease by a net $0.6 million, due mainly to a lapse in the applicable statute of limitations.

The Company and its subsidiaries are subject to U.S. federal income tax as well as income tax of multiple state, city and foreign jurisdictions. The Company's federal income tax returns for 2009 through the current period remain subject to examination and the relevant state, city and foreign statutes vary. There are no current tax examinations in progress where the Company expects the assessment of any significant additional tax in excess of amounts reserved.

Long-Term Debt

12 Months Ended

Dec. 31, 2012

Long-Term Debt [Abstract]

Long-Term Debt [Text Block]

(9)	Long-Term Debt

On July 27, 2012, Roper entered into a new $1.5 billion unsecured credit facility (the "2012 Facility") with JPMorgan Chase Bank, N.A., as administrative agent, and a syndicate of lenders, which replaced its existing unsecured credit facility dated as of July 7, 2008 (the "2008 Facility"). The 2012 Facility is composed of a five year $1.5 billion revolving credit facility. Roper may also, subject to compliance with specified conditions, request term loans or additional revolving credit commitments in an aggregate amount not to exceed $350 million. At December 31, 2012, there were $100 million of outstanding borrowings under the 2012 Facility. Roper recorded a $1.0 million non-cash debt extinguishment charge in the third quarter of 2012 related to the early termination of the 2008 Facility. This charge reflects the unamortized fees associated with the 2008 Facility and was reported as other expense.

On November 21, 2012, Roper completed a public offering of $400 million aggregate principal amount of 1.850% senior unsecured notes due November 15, 2017 and $500 million aggregate principal amount of 3.125% senior unsecured notes due November 15, 2022. The notes bear interest at a fixed rate of 1.850% and 3.125% per year, respectively, payable semi-annually in arrears on May 15 and November 15 of each year, beginning May 15, 2013.

Roper may redeem some or all of the notes at any time or from time to time, at 100% of their principal amount plus a make-whole premium based on a spread to U.S. Treasury securities as described in the indenture relating to the notes.

The notes are unsecured senior obligations of the Company and rank senior in right of payment with all of its existing and future unsecured and unsubordinated indebtedness and rank equally in right of payment with all of its existing and future unsecured senior indebtedness. The notes are effectively subordinated to any of Roper's existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness. The notes are not guaranteed by any of Roper's subsidiaries and are effectively subordinated to all existing and future indebtedness and other liabilities of its subsidiaries.

In September 2009, the Company completed a public offering of $500 million aggregate principal amount of 6.25% senior unsecured notes due September 2019. The notes bear interest at a fixed rate of 6.25% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning March 1, 2010.

Roper may redeem some of all of these notes at any time or from time to time, at 100% of their principal amount, plus a make-whole premium based on a spread to U.S. Treasury securities.

The notes are unsecured senior obligations of the Company and rank equally in right of payment with all of Roper's existing and future unsecured and unsubordinated indebtedness. The notes are effectively subordinated to any of its existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness. The notes are not guaranteed by any of Roper's subsidiaries and are effectively subordinated to all existing and future indebtedness and other liabilities of Roper's subsidiaries.

On August 6, 2008, Roper issued $500 million aggregate principal amount of 6.625% senior notes due August 15, 2013. The notes bear interest at a fixed rate of 6.625% per year, payable semi-annually in arrears on February 15 and August 15 of each year, beginning February 15, 2009. The interest payable on the notes is subject to adjustment if either Moody's Investors Service or Standard & Poor's Ratings Services downgrades the rating assigned to the notes.

The notes are unsecured senior obligations of the Company and rank equally in right of payment with all of the Company's existing and future unsecured and unsubordinated indebtedness. The notes are effectively subordinated to any of the Company's existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness. The notes are not guaranteed by any of the Company's subsidiaries and are effectively subordinated to all existing and future indebtedness and other liabilities of the Company's subsidiaries.

Other debt includes $12 million of senior subordinated convertible notes due 2034.

Total debt at December 31 consisted of the following (in thousands):

	2012		2011
$1.50 billion revolving credit facility	$	100,000	$	-
2013 Notes*		505,087		511,652
2017 Notes		400,000		-
2019 Notes		500,000		500,000
2022 Notes		500,000		-
Senior Subordinated Convertible Notes		11,594		67,250
Other		5,441		6,114
Total debt		2,022,122		1,085,016
Less current portion		519,015		69,906
Long-term debt	$	1,503,107	$	1,015,110

*Shown net of fair value swap adjustment of $5,087 at December 31, 2012 and $11,652 at December 31, 2011.

The 2012 Facility and Roper's $1.9 billion senior notes and senior subordinated convertible notes provide substantially all of Roper's daily external financing requirements. The interest rate on the borrowings under the 2012 Facility is calculated based upon various recognized indices plus a margin as defined in the credit agreement. At December 31, 2012, Roper's debt consisted of $1.9 billion of senior notes, $100 million of outstanding revolver borrowings and $12 million in senior subordinated convertible notes. In addition, the Company had $5.4 million of other debt in the form of capital leases, several smaller facilities that allow for borrowings or the issuance of letters of credit in foreign locations to support Roper's non-U.S. businesses and $43 million of outstanding letters of credit at December 31, 2012.

In December 2003, the Company issued through a public offering $230 million of 3.75% subordinated convertible notes due in 2034 at an original issue discount of 60.498% (the "Convertible Notes"). The Convertible Notes are subordinated in right of payment and collateral to all of Roper's existing and future senior debt. Cash interest on the notes was paid semi-annually until January 15, 2009, after which interest is recognized at the effective rate of 3.75% and represents accrual of original issue discount, and only contingent cash interest may be paid. Contingent cash interest may be paid during any six month period if the average trading price of a note for a five trading day measurement period preceding the applicable six month period equals 120% or more of the sum of the issue price, accrued original issue discount and accrued cash interest, if any, for such note. The contingent cash interest payable per note in respect of any six month period will equal the annual rate of 0.25%. In accordance with this criterion, contingent interest has been paid for each six month period since January 15, 2009. Holders receive cash up to the value of the accreted principal amount of the notes converted and, at the Company's option, any remainder of the conversion value may be paid in cash or shares of common stock. Holders may require Roper to purchase all or a portion of their notes on January 15, 2014 at a price of $475.66 per note, on January 15, 2019 at a price of $572.76 per note, on January 15, 2024 at a price of $689.68 per note, and on January 15, 2029 at a price of $830.47 per note, in each case plus accrued cash interest, if any, and accrued contingent cash interest, if any. The Company may only pay the purchase price of such notes in cash and not in common stock. In addition, if Roper experiences a change in control, each holder may require Roper to purchase for cash all or a portion of such holder's notes at a price equal to the sum of the issue price plus accrued original issue discount for non-tax purposes, accrued cash interest, if any, and accrued contingent cash interest, if any, to the date of purchase.

The Convertible Notes are classified as short-term debt as the notes became convertible on October 1, 2005 based upon the Company's common stock trading above the trigger price for at least 20 trading days during the 30 consecutive trading-day periods ending on September 30, 2005.

At December 31, 2012, the conversion price on the outstanding notes was $457.66. If converted at December 31, 2012, the value would have exceeded the $12 million principal amount of the notes by $23 million and could have resulted in the issuance of 211,962 shares of the Company's common stock.

The 2012 Facility contains affirmative and negative covenants which, among other things, limit Roper's ability to incur new debt, prepay subordinated debt, make certain investments and acquisitions, sell assets and grant liens, make restricted payments (including the payment of dividends on our common stock) and capital expenditures, or change its line of business. Roper is also subject to financial covenants which require the Company to limit its consolidated total leverage ratio and to maintain a consolidated interest coverage ratio. The most restrictive covenant is the consolidated total leverage ratio which is limited to 3.5.

The Company was in compliance with its debt covenants throughout the years ended December 31, 2012 and 2011.

Future maturities of long-term debt during each of the next five years ending December 31 and thereafter were as follows (in thousands):

2013	$	519,015
2014		1,404
2015		975
2016		533
2017		500,195
Thereafter		1,000,000
	$	2,022,122

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Fair Value

12 Months Ended

Dec. 31, 2012

Fair Value [Abstract]

Fair Value of Financial Instruments

(10)	Fair Value

Roper's debt at December 31, 2012 included $1.9 billion of fixed-rate senior notes with the following fair values (in millions):

$500 million senior notes due 2013	$	518
$400 million senior notes due 2017		399
$500 million senior notes due 2019		605
$500 million senior notes due 2022		509

The fair values of the senior notes are based on the trading prices of the notes, which the Company has determined to be Level 2 in the FASB fair value hierarchy. Short-term debt included $12 million of fixed-rate convertible notes which were at fair value due to the short-term nature of the notes. Most of Roper's other borrowings at December 31, 2012 were at various interest rates that adjust relatively frequently under its credit facility. The fair value for each of these borrowings at December 31, 2012 was estimated to be the face value of these borrowings.

In October 2009, Roper entered into interest rate swap agreements with an aggregate notional amount of $500 million. The swaps are designated as fair value hedges and effectively changed the Company's $500 million senior notes due 2013 with a fixed interest rate of 6.625% to a variable-rate obligation at a weighted-average spread of 4.377% plus LIBOR. The Company has determined the swaps to be Level 2 in the FASB fair value hierarchy. To account for the fair value hedge, the swap is recorded at fair value in the balance sheet as an asset or liability, and the changes in fair values of both the interest rate swap and the hedged senior notes due 2013 are recorded as interest expense. The fair value of the swap was an asset balance of $5.8 million and $11.6 million at December 31, 2012 and 2011, respectively. The corresponding change in the fair value of the notes being hedged was an increase of $5.1 million and $11.7 million at December 31, 2012 and 2011, respectively. The impact on earnings was immaterial in the years ended December 31, 2012, 2011 and 2010.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Stock-Based Compensation

12 Months Ended

Dec. 31, 2012

Stock-Based Compensation [Abstract]

Stock-Based Compensation [Text Block]

(12)	Stock-Based Compensation

The Roper Industries, Inc. Amended and Restated 2006 Incentive Plan ("2006 Plan") is a stock-based compensation plan used to grant incentive stock options, nonqualified stock options, restricted stock, stock appreciation rights or equivalent instruments to the Company's employees, officers, directors and consultants. The 2006 Plan replaced the Amended and Restated 2000 Incentive Plan ("2000 Plan"), and no additional grants will be made from the 2000 Plan. The number of shares reserved for issuance under the 2006 Plan is 14,000,000, plus the 17,000 remaining shares that were available to grant under the 2000 Plan at June 28, 2006, plus any shares underlying outstanding awards under the 2000 Plan that terminate or expire unexercised, or are cancelled, forfeited or lapse for any reason subsequent to June 28, 2006. At December 31, 2012, 6,941,775 shares were available to grant.

Under the Roper Industries, Inc., Employee Stock Purchase Plan ("ESPP"), all employees in the U.S. and Canada are eligible to designate up to 10% of eligible earnings to purchase Roper's common stock at a 5% discount to the average closing price of its common stock at the beginning and end of a quarterly offering period. The common stock sold to the employees may be either treasury stock, stock purchased on the open market, or newly issued shares.

Stock based compensation expense for the years ended December 31, 2012, 2011 and 2010 was as follows (in millions):

	2012		2011		2010
Stock based compensation	$	40.8	$	31.7	$	25.2
Tax benefit recognized in net income		14.3		11.1		8.8
Windfall tax benefit, net		30.8		12.7		7.3

Stock Options – Stock options are typically granted at prices not less than 100% of market value of the underlying stock at the date of grant. Stock options typically vest over a period of up to three to five years from the grant date and generally expire seven to ten years after the grant date. The Company recorded $14.8 million, $12.2 million, and $9.0 million of compensation expense relating to outstanding options during 2012, 2011 and 2010, respectively, as a component of corporate and certain segment general and administrative expenses.

The Company estimates the fair value of its option awards using the Black-Scholes option valuation model that uses the assumptions noted in the following table. The stock volatility for each grant is measured using the weighted-average of historical daily price changes of the Company's common stock over the most recent period equal to the expected life of the grant. The expected term of options granted is derived from historical data to estimate option exercises and employee terminations, and represents the period of time that options granted are expected to be outstanding. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The weighted-average fair value of options granted in 2012, 2011 and 2010 were calculated using the following weighted-average assumptions:

	2012		2011		2010
Weighted-average fair value ($)		30.25		24.45		17.00
Risk-free interest rate (%)		0.77		1.91		2.32
Average expected option life (years)		5.24		5.34		5.38
Expected volatility (%)		36.51		35.27		34.55
Expected dividend yield (%)		0.58		0.60		0.72

The following table summarizes the Company's activities with respect to its stock option plans for the year ended December 31, 2012:

	Number of shares			Weighted-average exercise price per share		Weighted-average contractual term		Aggregate intrinsic value

Business Segments [Abstract]

Business Segments [Text Block]

(14)	Segment and Geographic Area Information

Roper's operations are reported in four segments around common customers, markets, sales channels, technologies and common cost opportunities. The segments are: Industrial Technology, Energy Systems and Controls, Medical & Scientific Imaging, and RF Technology. Products included within the Industrial Technology segment are water and fluid handling pumps, flow measurement and metering equipment, industrial valves and controls, and equipment and consumables for materials analysis and industrial leak testing. The Energy Systems and Controls segment's products include control systems, equipment and consumables for fluid properties testing, vibration sensors and other non-destructive inspection and measurement products and services. The Medical and Scientific Imaging segment offers medical products and software, high performance digital imaging products and software and handheld and vehicle mounted computers. The RF Technology segment includes products and systems related to comprehensive toll and traffic systems and processing, security and access control, campus card systems, software-as-a-service applications in the freight matching and food industries and utility metering and remote monitoring applications. Roper's management structure and internal reporting are aligned consistently with these four segments.

There were no material transactions between Roper's business segments during 2012, 2011 and 2010. Sales between geographic areas are primarily of finished products and are accounted for at prices intended to represent third-party prices. Operating profit by business segment and by geographic area is defined as net sales less operating costs and expenses. These costs and expenses do not include unallocated corporate administrative expenses. Items below income from operations on Roper's statement of earnings are not allocated to business segments.

Identifiable assets are those assets used primarily in the operations of each business segment or geographic area. Corporate assets are principally comprised of cash and cash equivalents, deferred tax assets, recoverable insurance claims, deferred compensation assets, unamortized deferred financing costs and property and equipment.

Selected financial information by business segment for 2012, 2011 and 2010 follows (in thousands):

Tabular disclosure of liabilities, including [financial] instruments measured at fair value that are classified in stockholders' equity, if any, by class that are measured at fair value on a recurring and/or nonrecurring basis. The disclosures contemplated herein include the fair value measurements at the reporting date by the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3). Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.

Goodwill impairment method	The first step of the process utilizes both an income approach (discounted cash flows) and a market approach consisting of a comparable public company earnings multiples methodology to estimate the fair value of a reporting unit. To determine the reasonableness of the estimated fair values, the Company reviews the assumptions to ensure that neither the income approach nor the market approach provides significantly different valuations. If the estimated fair value exceeds the carrying value, no further work is required and no impairment loss is recognized. If the carrying value exceeds the estimated fair value, the goodwill of the reporting unit is potentially impaired and then the second step would be completed in order to measure the impairment loss by calculating the implied fair value of goodwill by deducting the fair value of all tangible and intangible net assets (including unrecognized intangible assets) of the reporting unit from the fair value of the reporting unit

New Accounting Pronouncement or Change in Accounting Principle, Description	In July 2012, the Financial Accounting Standards Board ("FASB") issued an amendment to accounting rules related to the testing of indefinite-lived intangibles. The new accounting rules permit an entity to first assess qualitative factors to determine if it is more likely than not that an indefinite-lived asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test prescribed under current accounting rules. The guidance is effective for annual and interim tests performed for fiscal years beginning after September 15, 2012. The Company does not expect these rules to have a material effect on its results of operations, financial position or cash flows.

This amendment requires the presentation of total comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. Roper adopted this guidance on January 1, 2012. The guidance did not have an impact on the Company's results of operations, financial position or cash flows as it is disclosure only in nature.

New Accounting Pronouncement or Change in Accounting Principle, Name	new accounting rules related to testing goodwill for impairment
New Accounting Pronouncement or Change in Accounting Principle, Description	In September 2011, the FASB issued new accounting rules related to testing goodwill for impairment. The new accounting rules permit an entity to first assess qualitative factors to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, it is necessary to perform the two-step goodwill impairment test prescribed under current accounting rules. Otherwise, the two-step goodwill impairment test is not required. Roper adopted this guidance on January 1, 2012. The guidance did not have a material effect on its results of operations, financial position or cash flows.
