Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements For assets and liabilities measured at fair value, such amounts are based on an expected exit price representing the amount that would be received from the sale of an asset or paid to transfer a liability in a transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs used in valuation techniques are assigned a hierarchical level. The following methods were used to estimate the fair value of each class of financial instruments for which it is practical to estimate that value:
• | Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
• | Level 2: Observable inputs that reflect quoted prices for identical assets or liabilities in markets that are not active, quoted prices for similar assets or liabilities in active markets, inputs other than quoted prices that are observable for the assets or liabilities, or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
• | Level 3: Unobservable inputs reflecting our own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.
Assets Measured at Fair Value on a Recurring Basis Cash equivalents. Cash equivalents consist of money market funds that are classified as Level 1, and have an original maturity of three months or less, and therefore the carrying amount is a reasonable estimate of fair value due to the short duration to maturity. There have been no transfers between fair value measurement levels during 2014 and 2013. The following table summarizes our assets measured at fair value on a recurring basis using Level 1 inputs within the fair value hierarchy:
| December 31, 2014 |  | December 31, 2013
| (In thousands)
Cash | $ | 61,311 |  |  | $ | 38,823 |
Cash equivalents | 64,577 |  |  | 65,708 |
Total cash and cash equivalents | $ | 125,888 |  |  | $ | 104,531 |
Net investment in sales-type leases. The carrying amount of our sales-type lease receivables is a reasonable estimate of fair value as the unearned interest income is immaterial. Assets and liabilities measured and recorded at fair value on a nonrecurring basis See Note 2, Business Combinations, for the fair value of intangible assets acquired that were calculated using an income approach valuation technique based on Level 3 unobservable inputs.

- 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. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 21 -URI http://asc.fasb.org/extlink&oid=35750535&loc=d3e13537-108611 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 10 -URI http://asc.fasb.org/extlink&oid=35750535&loc=d3e13433-108611 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 28 -URI http://asc.fasb.org/extlink&oid=6957238&loc=d3e14064-108612 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 820 -SubTopic 10 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=36462937&loc=d3e19207-110258 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 30 -URI http://asc.fasb.org/extlink&oid=6957238&loc=d3e14172-108612 Reference 6: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 16 -URI http://asc.fasb.org/extlink&oid=35750535&loc=d3e13504-108611 + Details
