1. Organization and Description of Business | |
        BioTelemetry, Inc. (the "Company," "BioTelemetry," "we" or "us"), a Delaware corporation, was formerly known as CardioNet, Inc. CardioNet, Inc. was reorganized under a holding company structure with the new name BioTelemetry, Inc. effective July 31, 2013. On August 1, 2013, the Company continued trading on NASDAQ under the symbol "BEAT". | |
        BioTelemetry, Inc. provides cardiac monitoring services, cardiac monitoring device manufacturing, and centralized cardiac core laboratory services. Since the Company became focused on cardiac monitoring in 1999, the Company has developed a proprietary integrated patient management platform that incorporates a wireless data transmission network, Food and Drug Administration ("FDA") cleared algorithms and medical devices, and 24-hour digital monitoring service centers. | |
        The Company operates under three segments: patient services, product and research services. The patient services segment is focused on the diagnosis and monitoring of cardiac arrhythmias, or heart rhythm disorders. The Company provides cardiologists and electrophysiologists who prefer to use a single source of cardiac monitoring services with a full spectrum of solutions, ranging from the differentiated Mobile Cardiac Outpatient TelemetryTM ("MCOT™") service to wEvent, event, Holter, Pacemaker and International normalized ratio ("INR") monitoring. INR monitoring is a measurement of blood coagulation in the circulatory system and is prescribed for patients on long term anticoagulation therapy. The product business segment focuses on the development, manufacturing, testing and marketing of medical devices to medical companies, clinics and hospitals. The research services segment is engaged in central core laboratory services providing cardiac monitoring, scientific consulting and data management services for drug and medical device trials. | |
        In August 2012, the Company completed the acquisition of Cardiocore Lab, Inc. ("Cardiocore"). Cardiocore is a central core laboratory that provides cardiac monitoring services for drug and medical treatment trials. Cardiocore's primary customers are pharmaceutical companies and contract research organizations. The acquisition gave the Company access to industry expertise, an established operating structure and a substantial footprint in the core lab industry. Cardiocore is included in the Company's research services segment. | |
        In February 2012, the Company completed the acquisition of ECG Scanning & Medical Services, Inc. ("ECG Scanning"). Similar to the Company's core patient services business, ECG Scanning was engaged in providing cardiac monitoring services to general practitioners, internal medicine specialists, cardiologists and hospital cardiac care departments. The acquisition gave the Company access to established customer relationships and provided cost synergies. ECG Scanning is included in the Company's patient services segment. | |
        On December 21, 2010, the Company completed the acquisition of Biotel Inc. ("Biotel"), and its wholly owned subsidiaries, Braemar, Inc. ("Braemar") and Agility Centralized Research Services, Inc. ("Agility"). Braemar develops, manufactures, and markets cardiac monitoring devices to healthcare companies, clinics and hospitals. Agility is a central core laboratory that provides cardiac monitoring service to medical device companies who are seeking FDA approval of their products. This acquisition provided access to an established customer base and diversified the Company's revenue by adding manufacturing and core laboratory services to its portfolio. Braemar is included in the Company's product segment, whereas Agility was repositioned during 2012 into the Company's research services segment. | |

2. Summary of Significant Accounting Policies | |||||||||||
Principles of Consolidation | |||||||||||
        The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. | |||||||||||
Use of Estimates | |||||||||||
        The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results may differ from those estimates. | |||||||||||
Fair Value of Financial Instruments | |||||||||||
        The Company's financial instruments consist mainly of cash and cash equivalents, accounts receivable, other current assets, accounts payable, deferred revenue and other current liabilities. The carrying value of these financial instruments approximates their fair value because of their short-term nature. The fair value of financial instruments is defined as the amount at which the instrument could be exchanged in a current transaction between willing parties. | |||||||||||
Cash and Cash Equivalents | |||||||||||
        Cash and cash equivalents are held in U.S. financial institutions or in custodial accounts with U.S. financial institutions. Cash equivalents are defined as liquid investments and money market funds with maturity from date of purchase of 90 days or less that are readily convertible into cash and have insignificant interest rate risk. | |||||||||||
Accounts Receivable and Allowance for Doubtful Accounts | |||||||||||
        Accounts receivable related to the patient services segment are recorded at the time revenue is recognized, net of contractual allowances, and are presented on the balance sheet net of allowance for doubtful accounts. The ultimate collection of accounts receivable may not be known for several months after services have been provided and billed. The Company records bad debt expense based on the aging of receivables using historical company specific data. The percentages and amounts used to record bad debt expense and the allowance for doubtful accounts are supported by various methods and analyses, including current and historical cash collections, and the aging of specific receivables. Because of continuing changes in the health care industry and third party reimbursement, it is possible that the Company's estimates of collectability could change, which could have a material impact on the Company's operations and cash flows. | |||||||||||
        Accounts receivable related to the product and research services segments are recorded at the time revenue is recognized, or when the services or products are billable, net of discounts. The Company estimates allowance for doubtful accounts on a specific account basis, and considers several factors in its analysis including customer specific information and aging of the account. | |||||||||||
        The Company writes off receivables when the likelihood for collection is remote and when the Company believes collection efforts have been fully exhausted and it does not intend to devote additional resources in attempting to collect. The Company performs write-offs on a monthly basis. In the patient services segment, the Company wrote off $7,919 and $14,184 of receivables for the years ended December 31, 2013 and 2012, respectively. The impact was a reduction of gross receivables and a reduction in the allowance for doubtful accounts. Additionally, the Company recorded bad debt expense of $7,787, $11,912 and $12,080 for the years ended December 31, 2013, 2012 and 2011, respectively. Based on collection experience, unfavorable adjustments of $1,480 and $6,343 were made to accounts receivable in 2013 and 2012, respectively, related to prior years accounts receivable. There were no write-offs in the product and research services segments. | |||||||||||
Concentrations of Credit Risk | |||||||||||
        Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents with high quality financial institutions to mitigate this risk. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company records an allowance for doubtful accounts in accordance with the procedures described above. Past-due amounts are written off against the allowance for doubtful accounts when collections are believed to be unlikely and all collection efforts have ceased. | |||||||||||
        At December 31, 2013, 2012 and 2011, one customer, Medicare, accounted for 18%, 20% and 19%, respectively, of the Company's net accounts receivable. | |||||||||||
Inventory | |||||||||||
        Inventory is valued at the lower of cost (using first-in, first-out cost method) or market (net realizable value or replacement cost). Company management periodically reviews inventory for specific future usage, and estimates of impairment of individual inventory items are recorded to reduce inventory to the lower of cost or market. | |||||||||||
Property and Equipment | |||||||||||
        Property and equipment is recorded at cost. Depreciation is recorded over the estimated useful life of each class of depreciable assets, and is computed using the straight-line method. Leasehold improvements are amortized over the shorter of the estimated asset life or term of the lease. Repairs and maintenance costs are charged to expense as incurred. | |||||||||||
Impairment of Long-Lived Assets | |||||||||||
        The Company periodically evaluates the recoverability of the carrying value of its long-lived assets based on the criteria established in Accounting Standards Codification (ASC) 360, Property, Plant & Equipment. The Company considers historical performance and anticipated future results in its evaluation of potential impairment. Accordingly, when indicators of impairment are present, the Company evaluates the carrying value of these assets in relation to the operating performance of the business and the undiscounted cash flows expected to result from the use of these assets. Impairment losses are recognized when the sum of the expected future cash flows is less than the assets' carrying value. | |||||||||||
Goodwill and Acquired Intangible Assets | |||||||||||
        Goodwill is the excess of purchase price of an acquired business over the amounts assigned to assets acquired and liabilities assumed in a business combination. In accordance with ASC 350, Intangibles—Goodwill and Other, goodwill is reviewed for impairment annually, or when events arise that could indicate that impairment exists. The provisions of ASC 350 require that the Company perform a two-step impairment test. In the first step, the Company compares the fair value of its reporting units to the carrying value of the reporting units. If the carrying value of the net assets assigned to the reporting units exceeds the fair value of the reporting units, then the second step of the impairment test is performed in order to determine the implied fair value of the reporting units' goodwill. If the carrying value of the reporting units' goodwill exceeds its implied fair value, an impairment loss equal to the difference is recorded. | |||||||||||
        For the purpose of performing its goodwill impairment analysis in 2013, the Company considers its business to be comprised of three reporting units, patient services, product and research services. The Company calculates the fair value of the reporting units utilizing the income and market approaches. The income approach is based on a discounted cash flow methodology that includes assumptions for, among other things, forecasted income, cash flow, growth rates, income tax rates, expected tax benefits and long-term discount rates, all of which require significant judgment. The market approach utilizes the Company's market data. There are inherent uncertainties related to these factors and the judgment applied in the analysis. The Company believes that the combination of an income and a market approach provides a reasonable basis to estimate the fair value of its reporting units. | |||||||||||
Revenue Recognition | |||||||||||
        The Company recognizes approximately 78% of its total revenue from patient monitoring services in its patient services segment, derived from its MCOT™, wEvent, event, Holter, Pacemaker and INR services. The Company receives a significant portion of its revenue from third party commercial payors and governmental entities. It also receives reimbursement directly from patients through co-pay, deductibles and self-pay arrangements. | |||||||||||
        Revenue from the Medicare program is based on reimbursement rates set by CMS. Revenue from contracted commercial payors is recorded at the negotiated contractual rate. Revenue from non-contracted commercial payors is recorded at net realizable value based on historical payment patterns. Adjustments to the estimated net realizable value, based on final settlement with the third party payors, are recorded upon settlement. If the Company does not have consistent historical information regarding collectability from a given payor, revenue is recognized when cash is received. Unearned amounts are appropriately deferred until service is performed. For the years ended December 31, 2013, 2012 and 2011, revenue from Medicare as a percentage of total Company revenue was 35%, 37% and 33%, respectively. | |||||||||||
        Revenue received from the sale of products, product repair and supplies is recognized when shipped, or as service is completed. Unearned amounts are appropriately deferred until service is performed. | |||||||||||
        Research services revenue includes revenue for research and core laboratory services. The Company's research services revenues are provided on a fee for service basis, and revenue is recognized as the related services are performed. We also provide consulting services on a time and materials basis and recognize revenues as we perform the services. Our site support revenue, consisting of equipment rentals and sales along with related supplies and logistics management, are recognized at the time of sale or over the rental period. Under a typical contract, customers pay us a portion of our fee for these services upon contract execution as an upfront deposit, some of which is typically nonrefundable upon contract termination. Unearned revenues are deferred, and then recognized as the services are performed. | |||||||||||
        For arrangements with multiple deliverables, the revenue is allocated to each element (both delivered and undelivered items) based on their relative selling prices or management's best estimate of their selling prices, when vendor-specific or third-party evidence is unavailable. | |||||||||||
        We record reimbursements received for out-of-pocket expenses, including freight, incurred as revenue in the accompanying consolidated statements of operations. Revenue generally is recognized net of any taxes collected from customers and subsequently remitted to government authorities. | |||||||||||
Advertising Costs | |||||||||||
        Advertising costs are charged to expense as incurred. For the years ended December 31, 2013, 2012 and 2011, the Company incurred advertising costs of $223, $174 and $218, respectively. | |||||||||||
Research and Development Costs | |||||||||||
        Research and development costs are charged to expense as incurred. | |||||||||||
Net Loss | |||||||||||
        The Company computes net loss per share in accordance with ASC 260, Earnings Per Share. Basic net loss per share is computed by dividing net loss per share available to common shareholders by the weighted average number of common shares outstanding for the period, and excludes the effects of any potentially dilutive securities. Diluted earnings per share, if presented, would include the dilution that would occur upon the exercise or conversion of all potentially dilutive securities into common stock using the treasury stock or if converted methods, as applicable. | |||||||||||

Stock-Based Compensation | |||||||||||
        ASC 718, Compensation—Stock Compensation, addresses the accounting for share-based payment transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprise's equity instruments or that may be settled by the issuance of such equity instruments. ASC 718 requires that an entity measures the cost of equity-based service awards based on the grant-date fair value of the award and recognizes the cost of such awards over the period during which the employee is required to provide service in exchange for the award (the vesting period). ASC 718 requires that an entity measures the cost of liability-based service awards based on current fair value that is re-measured subsequently at each reporting date through the settlement date. The Company accounts for equity awards issued to non-employees in accordance with ASC 505-50, Equity-Based Payments to Non-Employees. | |||||||||||
Income Taxes | |||||||||||
        The Company accounts for income taxes under the liability method, as described in ASC 740, Income Taxes. Deferred income taxes are recognized for the tax consequences of temporary differences between the tax and financial statement reporting bases of assets and liabilities. A valuation allowance for net deferred tax assets is provided unless realizability is judged by the Company to be more likely than not. | |||||||||||
Segment Information | |||||||||||
        ASC 280, Segment Reporting, establishes standards for reporting information regarding operating segments in annual financial statements. Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision-maker, or decision-making group in making decisions on how to allocate resources and assess performance. | |||||||||||
        Effective in the third quarter 2012, with the acquisition of Cardiocore, the Company changed its reportable segments from two segments: patient services and product, to three segments: patient services, product and research services. The patient services business segment's principal focus is on the diagnosis and monitoring of cardiac arrhythmias or heart rhythm disorders, through its core Mobile Cardiac Outpatient TelemetryTM (MCOTTM), wEvent, event, Holter and Pacemaker services, as well as INR services in a healthcare setting. The Product business segment focuses on the development, manufacturing, testing and marketing of medical devices to medical companies, clinics and hospitals. The Research services segment includes the Company's operations that engage in central core laboratory services in a research environment, which includes certain equipment rental and product sales. In addition, the Company realigned the Product segment to exclude central core laboratory research operations previously reported in this segment and repositioned these operations into the Research services segment. Disclosures for the twelve months ended December 31, 2012 have been adjusted to reflect the change in reportable segments. | |||||||||||
Recent Accounting Pronouncements | |||||||||||
        In July 2012, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2012-02, Intangibles—Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. The new guidance allows an entity the option to first assess qualitative factors to determine whether the existence of events and circumstances indicate that it is more likely than not that the indefinite-lived intangible asset is impaired. If the qualitative assessment leads to the determination that is more likely than not that the indefinite-lived intangible asset is impaired, then the entity is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. The ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The amendment did not have a material impact on the Company's results of operations, cash flows, or financial position. | |||||||||||
        In February 2013, FASB issued ASU 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The new guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The ASU is effective prospectively for reporting periods beginning after December 15, 2012. The amendment did not have a material impact on the Company's results of operations, cash flows, or financial position. | |||||||||||
        In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The new guidance provides specific financial statement presentation requirements of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance states that an unrecognized tax benefit in those circumstances should be presented as a reduction to the deferred tax asset. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The Company does not expect the amendment to have a material impact on its results of operations, cash flows, or financial position. | |||||||||||

        On February 10, 2012, the Company entered into and closed on a definitive Stock Purchase Agreement (the "Stock Purchase Agreement") with ECG Scanning and Medical Services, Inc., an Ohio corporation ("ECG Scanning"). Upon the closing of the transaction, the Company acquired all of the issued and outstanding capital stock, and ECG Scanning became a wholly-owned subsidiary of the Company. ECG Scanning was a provider of cardiac monitoring services in the United States. The Company paid an aggregate cash purchase price of $5,800 at closing and up to an additional $600 in cash, with an estimated fair value of $570, upon the achievement of certain performance targets approximately one year from the date of purchase. At December 31, 2012 the estimated fair value of the earn out was $0. The reduction of the liability was recognized in the Statement of Operations and Comprehensive Income (Loss) in the Integration, restructuring, and other line. The acquisition has been included within the consolidated results of operations and financial condition from the date of the acquisition. The acquisition gave the Company access to established customer relationships, and entry into additional regions and geographic locations. | ||||||||

        At December 31, 2013 and 2012, the Company performed its required annual impairment test of goodwill. Based on this impairment test, the Company determined that none of the reporting unit's goodwill was impaired. | ||||||||||||||
        At December 31, 2011, the Company performed its required annual impairment test of goodwill. Based on this impairment test, the Company determined that its Product reporting unit's goodwill was not impaired. However, as a result of the impairment test, the Company determined that impairment may exist in the patient services reporting unit. Therefore, the Company performed Step 2 of the goodwill impairment analysis on its patient services reporting unit. | ||||||||||||||
        The Step 2 analysis was performed by allocating the fair value of the patient services reporting unit to the identifiable assets, including unrecorded intangible assets and liabilities. This allocation is performed as if the reporting unit had been acquired in a business combination, and assumes the purchase price was equivalent to the fair value determined in Step 1 of the goodwill impairment test. The residual fair value of the reporting unit after allocation is the implied fair value of goodwill. This value is then compared to the carrying value of the reporting unit's goodwill. If the implied fair value of goodwill is less than the carrying value, impairment exists and a charge is recorded in the amount of the difference. As a result of the Company's analysis, an impairment charge of $45,999 was recorded for the year ended December 31, 2011 related to the patient services reporting unit. | ||||||||||||||

2008 Equity Incentive Plan | ||||||||||||||||||||
        The Company's 2008 Equity Incentive Plan (the 2008 Option Plan) became effective on March 18, 2008. The Plan permits the Company's Board of Directors to grant incentive stock options to employees of the Company and non-qualified stock options, restricted stock, performance stock and other stock-based incentive awards to officers, directors, employees and consultants of the Company. On that date, the Company began granting options to purchase shares of common stock to employees, executives, directors and consultants. Under the terms of the 2008 Option Plan, all available shares in the 2003 Option Plan's share reserve automatically roll into the 2008 Option Plan. Any cancellations or forfeitures of granted options under the 2003 Option Plan also automatically roll into the 2008 Option Plan. Beginning on January 1, 2009, and each year thereafter, the number of options available to be granted under the plan will increase by the lesser of 4% of the total number of common shares outstanding or 1,500,000 shares. | ||||||||||||||||||||
        Options granted under the 2008 Option Plan have exercise prices not less than the fair market value at the date of grant and have an expiration date of no greater than ten years from the date of grant. There is no vesting schedule provided in the 2008 Option Plan, and vesting is determined by the Board of Directors on the date of grant. | ||||||||||||||||||||
2008 Non-employee Directors' Stock Option Plan | ||||||||||||||||||||
        As of October 23, 2008, the Company no longer granted options to purchase shares of common stock to non-employee directors under the Company's 2008 Non-employee Directors' Stock Option Plan (the 2008 Directors' Plan). The Company's 2008 Directors' Plan became effective March 18, 2008. Beginning on that date, all directors elected for the first time to the Board of Directors receive a fixed number of options. On the date of the annual meeting, and when directors are elected to a committee or a chair position of a committee, they will also receive a grant equal to a fixed number of options per the Directors' Plan. Options granted under the Directors' Plan have exercise prices not less than the fair market value at the date of grant, and have an expiration date of no greater than ten years from the date of grant. Initial and committee chair grants vest 33% on the first anniversary date of grant, and the balance vests ratably over 24 months. Annual grants vest ratably over 12 months from the date of grant. | ||||||||||||||||||||
2003 Equity Incentive Plan | ||||||||||||||||||||
        As of March 18, 2008, the Company no longer granted options to purchase shares of common stock to employees, executives, directors and consultants under the Company's 2003 Equity Incentive Plan (the 2003 Option Plan). Options granted under the 2003 Option Plan have exercise prices not less than the fair market value at date of grant for incentive stock options and not less than 85% of the fair market value at the date of grant for non-statutory options. The options generally expire ten years from the date of grant and generally vest 25% twelve months from the date of grant, and ratably over the next 36 months thereafter. | ||||||||||||||||||||
        The 2003 Option Plan allows for employees to early exercise options on the first anniversary date of employment, regardless of the vested status of granted options. If an employee terminates prior to fully vesting in options that have been early exercised, the Company repurchases the common stock associated with unvested options at the original exercise price. | ||||||||||||||||||||

        The Company's loss before income taxes for the years ended December 31, 2013, 2012 and 2011 was $3,303, $3,747 and $4,006 lower, respectively, as a result of stock- based compensation expense incurred. For the year ended December 31, 2013, the impact of stock-based compensation expense was $(0.13) on the basic and diluted earnings per share. The impact of stock-based compensation expense was $(0.15) and $(0.16) on the basic and diluted earnings per share for the years ended December 31, 2012 and 2011. Stock-based compensation expense was recorded in general and administrative expenses for the years ended 2013, 2012 and 2011. | ||||||||||||||||||||
        Total cash received from the exercise of stock options for the year ended December 31, 2013, 2012 and 2011 was $467, $4 and $11, respectively. The tax benefit was fully reserved for through a tax valuation allowance. | ||||||||||||||||||||
        The Company estimates the fair value of its share-based awards to employees and directors using the Black-Scholes option valuation model. The Black-Scholes option valuation model requires the use of certain subjective assumptions. The most significant of these assumptions are the estimates of the expected volatility of the market price of the Company's stock and the expected term of the award. We base our estimates of expected volatility on the historical volatility of our stock price. The expected term represents the period of time that stock-based awards granted are expected to be outstanding. Other assumptions used in the Black-Scholes option valuation model include the risk-free interest rate and expected dividend yield. The risk-free interest rate for periods pertaining to the contractual life of each option is based on the U.S. Treasury yield of a similar duration in effect at the time of grant. The Company has never paid, and does not expect to pay, dividends in the foreseeable future. | ||||||||||||||||||||
        The fair value of the Company's stock-based awards was estimated at the date of grant using the following weighted average assumptions: | ||||||||||||||||||||

        Based on the Company's historical experience of options that cancel before becoming fully vested, the Company has assumed an annualized forfeiture rate of 15% for all options. Under the true-up provision of ASC 718, the Company will record additional expense if the actual forfeiture rate is lower than estimated, and will record a recovery of prior expense if the actual forfeiture rate is higher than estimated. | ||||||||||||||||||||
        Total compensation cost of options granted but not yet vested at December 31, 2013, 2012 and 2011 were approximately $2,644, $3,433 and $3,615, respectively. At December 31, 2013, 2012 and 2011, the weighted average remaining periods over which the above amounts are expected to be recognized were 2.14 years, 2.34 years and 2.62 years, respectively. At December 31, 2013, 2,404,498 shares remained available for future grant under the Plan. | ||||||||||||||||||||

Option Acceleration | ||||||||||||||||||||
        On December 1, 2009, the Company accelerated the vesting of certain employees' unvested options that were deeply out-of-the-money. The acceleration was done because the Company believed that there was no longer a compensation incentive tied to Company performance, given the exercise price of the options that were accelerated. Consistent with ASC 718, the Company will continue to expense the accelerated options over the remaining service period. The Company does not have a static policy threshold to use for determining whether an option is deeply out-of-the-money. Rather, the Company believes that the determination should be made in light of current market conditions, probability of stock price recovery within the remaining service period, and historical volatility of the Company's stock price. For the purposes of this option acceleration, the Company determined that options that were out-of-the-money by 30% or more were deeply out-of-the-money. As a result of the option acceleration, approximately 309,000 previously unvested shares became fully vested on December 1, 2009. The Company incurred an expense associated with the options that were accelerated in the amount of $137, $578 and $984 for the years ended December 31, 2013, 2012 and 2011, respectively, which have been recorded in the General and administrative line of the consolidated statement of operations and comprehensive income (loss). The weighted average exercise price of the accelerated options is $19.87, and the remaining service period has elapsed. | ||||||||||||||||||||
Employee Stock Purchase Plan | ||||||||||||||||||||
        In July 2008, the Company made available an employee stock purchase plan in which substantially all of the Company's full-time employees became eligible to participate effective March 18, 2008. Under the plan, employees may contribute through payroll deductions up to 15% of their compensation toward the purchase of the Company's common stock, or $21, whichever is lower. The price per share is equal to the lower of 85% of the fair market price on the first day of the offering period, or 85% of the fair market price on the day of purchase. Proceeds received from the issuance of shares are credited to stockholders' equity in the period that the shares are issued. In 2013, 243,185 shares were purchased in accordance with the Employee Stock Purchase Plan (ESPP). Net proceeds to the Company from the issuance of shares of common stock under the ESPP for the year ended December 31, 2013 were $487. In January 2013, the number of shares available for grant was increased by 252,154, per the ESPP plan documents. At December 31, 2013, approximately 517,456 shares remain available for purchase under the ESPP. For the years ended December 31, 2013, 2012 and 2011, the Company incurred ESPP expenses of $211, $182 and $201, respectively. | ||||||||||||||||||||

        The Company has deferred income tax assets totaling $53,584 at December 31, 2013, consisting primarily of federal and state net operating loss and credit carryforwards. Due to uncertainty regarding the ultimate realization of these net operating loss and credit carryforwards and other deferred income tax assets, we have established a full valuation allowance on our deferred tax assets and will recognize the benefits only as reassessment indicates the benefits are realizable. The determination of the required valuation allowance against net deferred tax assets was made without taking into account the deferred tax liabilities created from the book and tax differences on indefinite-lived assets. | |||||||||||
        The Company's income tax expense for 2013 of $215 primarily relates to state taxes based on gross receipts or modified gross receipts calculations properly included as income taxes. | |||||||||||
        The Company performed an analysis to determine the extent to which it can use its net operating loss carryforwards in future periods, subject to certain limitations imposed by the Internal Revenue Code. The Company concluded that because of the Company's limited history of reporting a net profit, it cannot predict that the benefits of the net operating loss carryfowards will be realized in future periods, and therefore the Company continues to provide a full valuation allowance for deferred tax assets. The Company will perform a similar analysis during 2014 to reassess the estimated future realizability of net operating loss carryforwards. | |||||||||||
        Deferred taxes result from temporary differences between the carrying amounts of assets and liabilities used for financial reporting purposes and the amounts used for income tax purposes.

        At December 31, 2013, the Company had federal net operating loss carryforwards of approximately $96,588, to offset future federal taxable income expiring in various years through 2030. At December 31, 2013, the Company had state net operating loss carryforwards of $54,243, which expire in various years starting in 2014. | |||||||||||
        The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences are deductible. The timing and manner in which the Company can utilize its net operating loss carryforward and future income tax deductions in any year may be limited by provisions of the Internal Revenue Code regarding the change in ownership of corporations. Such limitation may have an impact on the ultimate realization of the Company's carryforwards and future tax deductions. Section 382 of the Internal Revenue Code ("Section 382") imposes limitations on a corporation's ability to utilize net operating losses if it experiences an "ownership change." In general terms, an ownership change may result from transactions increasing the ownership of certain stockholders in the stock of a corporation by more than 50 percentage points over a three-year period. Any unused annual limitation may be carried over to later years, and the amount of the limitation may under certain circumstances be increased by the built-in gains in assets held by the Company at the time of the change that are recognized in the five-year period after the change. Currently, the Company's loss carryforwards are limited under Section 382. | |||||||||||

Interest on borrowings under the Credit Agreement is based on the London Interbank Offered Rate ("LIBOR") plus a margin of 4.75%. An unused line fee of 0.50% per annum is payable on any unused line balance, determined as the total loan commitment of $15,000 minus the average daily balance of the sum of the revolving loan borrowings outstanding during the preceding month. Furthermore, if the Company terminates the agreement at any point prior to the loan expiration date, the Company will incur a loan termination fee of 1.00% of the loan commitment due immediately preceding the termination. The Credit Agreement is secured by the Company's personal property, inventory and other assets and expires in August 2016.

CardioNet v. Mednet Litigation | |
        On May 8, 2012, CardioNet, Inc. filed suit against Mednet Healthcare Technologies, Inc., MedTel 24, Inc., RhythmWatch LLC, and AMI Cardiac Monitoring, Inc., in the United States District Court for the Eastern District of Pennsylvania (Civil Action No. 2:12-CV-2517-JS) for patent infringement related to the making, use, offering for sale, and sale of the Heartrak ECAT device and monitoring services. The suit asserted that the defendants are infringing CardioNet's U.S. Patent Nos. 7,212,850, 7,907,996, 6,569,095, 7,587,237 and 7,941,207. CardioNet sought an injunction against each defendant, as well as monetary damages. The defendants asserted counterclaims alleging the patents in suit are invalid and not infringed. | |
        This litigation concluded on January 31, 2014 when the Court entered a Consent Judgment declaring all five CardioNet patents valid and enforceable, and infringed by the defendants' making, using, offering to sell, or selling the Heartrak ECAT device and monitoring services. The Consent Judgment also declared that all defendants are permanently enjoined from further infringement and are required to turn over all existing inventory of the Heartrak ECAT system to CardioNet and Braemar. | |
        Simultaneously with the entry on of the consent judgment the Company, through its CardioNet subsidiary, entered into a definitive stock purchase agreement, to purchase all of the outstanding capital stock of Mednet and its affiliated entities for consideration of $5.5 million in cash and 96,649 shares of the Company's common stock. In addition, as a result of the acquisition, the Company, through CardioNet, assumed outstanding secured debt of the Mednet entities in the aggregate amount of approximately $10 million, including interest. | |
CardioNet v. ScottCare Litigation | |
        On May 8, 2012, CardioNet, Inc. filed suit against The ScottCare Corporation and Ambucor Health Solutions, Inc. in the United States District Court for the Eastern District of Pennsylvania (Civil Action No. 2:12-CV-2516-PBT) for patent infringement under the same five CardioNet patents, as mentioned above in the Mednet litigation, related to the making, use, sale, and offering for sale of the ScottCare TeleSentry Mobile Cardiac Telemetry device and monitoring services. CardioNet is seeking an injunction against each defendant, as well as monetary damages. The ScottCare Corporation has asserted counterclaims alleging the patents in suit are invalid and not infringed. | |
        On May 10, 2013, CardioNet, Inc. and Braemar Manufacturing, LLC filed an Amended Complaint identifying Braemar as the new owner of all right, title and interest to the patents-in-suit with CardioNet as the exclusive licensee of these patents. Fact discovery is scheduled to close on April 17, 2014, with trial scheduled for November 10, 2014. Consistent with the accounting for contingent liabilities, no accrual has been recorded in the financial statements. The Company is vigorously pursuing its claims and defending against the counterclaims. | |
CardioNet v. LifeWatch Litigation | |
        On June 12, 2012, CardioNet, Inc. settled the patent infringement action brought on September 25, 2009 by LifeWatch Services, Inc., and Card Guard Scientific Survival, Ltd. ("Lifewatch"), the licensee and owner, respectively, of U.S. Patent Nos. 7,542,878 B2 ("the '878 Patent") and 5,730,143 ("the '143 Patent"), collectively ("Licensed Patents") against the Company's wholly owned subsidiary, Braemar Inc. ("Braemar") and one of its customers, eCardio Diagnostics, LLC ("eCardio"), in Federal District Court for the Northern District of Illinois, File No. 09-CV-6001. In this matter, Lifewatch alleged that Braemar and eCardio had infringed the Licensed Patents. Pursuant to the terms of the settlement agreement, the Company paid Lifewatch a lump sum of $250 for a fully paid license, release, and covenant not to sue under the Licensed Patents for Braemar products. The covenant not to sue extends to Braemar's customers, including eCardio. | |

16. Civil Investigative Demand | |
        On August 25, 2011, the Company received a Civil Investigative Demand ("CID") issued by the U.S. Department of Justice, Western District of Washington. The CID states that it was issued in the course of an investigation under the federal false claims act and seeks documents for the period January 1, 2007 through the date of the CID. The CID indicates that the investigation concerns allegations that the Company may have used inappropriate diagnosis codes when submitting claims for payment to Medicare for its real-time, outpatient cardiac monitoring services. The Company is cooperating with the government's request and is in the process of providing information in response to the CID. The Company is unable to predict what action, if any, might be taken in the future by the Department of Justice or other governmental authorities as a result of this investigation or what impact, if any, the outcome of this matter might have on the Company's business, financial position or results of operations. The Company cannot reasonably estimate the range of loss, if any, that may result from this matter. Consistent with the accounting for contingent liabilities, no accrual has been recorded in the financial statements. | |

        On January 31, 2014, the Company, through its wholly-owned subsidiary CardioNet, acquired Mednet Healthcare Technologies, Inc., Heartcare Corporation of America, Inc., Universal Medical, Inc., and Universal Medical Laboratory, Inc. (together, the "Mednet entities") from Frank Movizzo ("Seller"), pursuant to the terms and conditions of a Stock Purchase Agreement among CardioNet, the Mednet entities and Mr. Movizzo (the "Purchase Agreement"). | |
        The Purchase Agreement was entered into following the entry of a consent judgment in connection with the Company's patent infringement action originally filed in the U.S. District Court for the Eastern District of Pennsylvania in May 2012 against the Mednet entities and other companies. The consent judgment declared that the Mednet entities infringed five patents owned by the Company and its subsidiary, Braemar Manufacturing, LLC, and that all five patents are valid. | |
        Pursuant to the terms of the Purchase Agreement, CardioNet purchased all of the outstanding capital stock of the Mednet entities from the Seller for consideration of $5.5 million in cash and 96,649 shares of the Company's common stock. In addition, as a result of the acquisition, the Company, through CardioNet, assumed outstanding secured debt of the Mednet entities in the aggregate amount of approximately $10 million, including interest. | |
        On February 21, 2014, the Company came to an agreement with the third party lenders to refinance this debt. The Loans bear interest at an annual rate of 3.25% until March 1, 2019, and thereafter will bear interest at an annual rate equal to the greater of (1) 3.25% or (2) the prime rate as published in the "Money Rates" section of The Wall Street Journal (or it successor) or the highest prime rate if more than one is published. Beginning April 1, 2014, the principal amount of the Loans will be repaid, on a monthly basis, in installments of $37,500, plus accrued interest, until April 1, 2019, when the principal amount of the Loans will be repaid, on a monthly basis, in installments of $75,000, plus accrued interest, until paid in full on or before March 1, 2024 (or such earlier date upon an acceleration of the Loans by Lenders upon an event of default or termination by the Borrowers). | |

Principles of Consolidation | ' | ||||||||||
Principles of Consolidation | |||||||||||
        The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. | |||||||||||
Use of Estimates | ' | ||||||||||
Use of Estimates | |||||||||||
        The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires that management make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results may differ from those estimates. | |||||||||||
Fair Value of Financial Instruments | ' | ||||||||||
Fair Value of Financial Instruments | |||||||||||
        The Company's financial instruments consist mainly of cash and cash equivalents, accounts receivable, other current assets, accounts payable, deferred revenue and other current liabilities. The carrying value of these financial instruments approximates their fair value because of their short-term nature. The fair value of financial instruments is defined as the amount at which the instrument could be exchanged in a current transaction between willing parties. | |||||||||||
Cash and Cash Equivalents | ' | ||||||||||
Cash and Cash Equivalents | |||||||||||
        Cash and cash equivalents are held in U.S. financial institutions or in custodial accounts with U.S. financial institutions. Cash equivalents are defined as liquid investments and money market funds with maturity from date of purchase of 90 days or less that are readily convertible into cash and have insignificant interest rate risk. | |||||||||||
Accounts Receivable and Allowance for Doubtful Accounts | ' | ||||||||||
Accounts Receivable and Allowance for Doubtful Accounts | |||||||||||
        Accounts receivable related to the patient services segment are recorded at the time revenue is recognized, net of contractual allowances, and are presented on the balance sheet net of allowance for doubtful accounts. The ultimate collection of accounts receivable may not be known for several months after services have been provided and billed. The Company records bad debt expense based on the aging of receivables using historical company specific data. The percentages and amounts used to record bad debt expense and the allowance for doubtful accounts are supported by various methods and analyses, including current and historical cash collections, and the aging of specific receivables. Because of continuing changes in the health care industry and third party reimbursement, it is possible that the Company's estimates of collectability could change, which could have a material impact on the Company's operations and cash flows. | |||||||||||
        Accounts receivable related to the product and research services segments are recorded at the time revenue is recognized, or when the services or products are billable, net of discounts. The Company estimates allowance for doubtful accounts on a specific account basis, and considers several factors in its analysis including customer specific information and aging of the account. | |||||||||||
        The Company writes off receivables when the likelihood for collection is remote and when the Company believes collection efforts have been fully exhausted and it does not intend to devote additional resources in attempting to collect. The Company performs write-offs on a monthly basis. In the patient services segment, the Company wrote off $7,919 and $14,184 of receivables for the years ended December 31, 2013 and 2012, respectively. The impact was a reduction of gross receivables and a reduction in the allowance for doubtful accounts. Additionally, the Company recorded bad debt expense of $7,787, $11,912 and $12,080 for the years ended December 31, 2013, 2012 and 2011, respectively. Based on collection experience, unfavorable adjustments of $1,480 and $6,343 were made to accounts receivable in 2013 and 2012, respectively, related to prior years accounts receivable. There were no write-offs in the product and research services segments. | |||||||||||
Concentrations of Credit Risk | ' | ||||||||||
Concentrations of Credit Risk | |||||||||||
        Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable. The Company maintains its cash and cash equivalents with high quality financial institutions to mitigate this risk. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company records an allowance for doubtful accounts in accordance with the procedures described above. Past-due amounts are written off against the allowance for doubtful accounts when collections are believed to be unlikely and all collection efforts have ceased. | |||||||||||
        At December 31, 2013, 2012 and 2011, one customer, Medicare, accounted for 18%, 20% and 19%, respectively, of the Company's net accounts receivable. | |||||||||||
Inventory | ' | ||||||||||
Inventory | |||||||||||
        Inventory is valued at the lower of cost (using first-in, first-out cost method) or market (net realizable value or replacement cost). Company management periodically reviews inventory for specific future usage, and estimates of impairment of individual inventory items are recorded to reduce inventory to the lower of cost or market. | |||||||||||
Property and Equipment | ' | ||||||||||
Property and Equipment | |||||||||||
        Property and equipment is recorded at cost. Depreciation is recorded over the estimated useful life of each class of depreciable assets, and is computed using the straight-line method. Leasehold improvements are amortized over the shorter of the estimated asset life or term of the lease. Repairs and maintenance costs are charged to expense as incurred. | |||||||||||
Impairment of Long-Lived Assets | ' | ||||||||||
Impairment of Long-Lived Assets | |||||||||||
        The Company periodically evaluates the recoverability of the carrying value of its long-lived assets based on the criteria established in Accounting Standards Codification (ASC) 360, Property, Plant & Equipment. The Company considers historical performance and anticipated future results in its evaluation of potential impairment. Accordingly, when indicators of impairment are present, the Company evaluates the carrying value of these assets in relation to the operating performance of the business and the undiscounted cash flows expected to result from the use of these assets. Impairment losses are recognized when the sum of the expected future cash flows is less than the assets' carrying value. | |||||||||||
Goodwill and Acquired Intangible Assets | ' | ||||||||||
Goodwill and Acquired Intangible Assets | |||||||||||
        Goodwill is the excess of purchase price of an acquired business over the amounts assigned to assets acquired and liabilities assumed in a business combination. In accordance with ASC 350, Intangibles—Goodwill and Other, goodwill is reviewed for impairment annually, or when events arise that could indicate that impairment exists. The provisions of ASC 350 require that the Company perform a two-step impairment test. In the first step, the Company compares the fair value of its reporting units to the carrying value of the reporting units. If the carrying value of the net assets assigned to the reporting units exceeds the fair value of the reporting units, then the second step of the impairment test is performed in order to determine the implied fair value of the reporting units' goodwill. If the carrying value of the reporting units' goodwill exceeds its implied fair value, an impairment loss equal to the difference is recorded. | |||||||||||
        For the purpose of performing its goodwill impairment analysis in 2013, the Company considers its business to be comprised of three reporting units, patient services, product and research services. The Company calculates the fair value of the reporting units utilizing the income and market approaches. The income approach is based on a discounted cash flow methodology that includes assumptions for, among other things, forecasted income, cash flow, growth rates, income tax rates, expected tax benefits and long-term discount rates, all of which require significant judgment. The market approach utilizes the Company's market data. There are inherent uncertainties related to these factors and the judgment applied in the analysis. The Company believes that the combination of an income and a market approach provides a reasonable basis to estimate the fair value of its reporting units. | |||||||||||
Revenue Recognition | ' | ||||||||||
Revenue Recognition | |||||||||||
        The Company recognizes approximately 78% of its total revenue from patient monitoring services in its patient services segment, derived from its MCOT™, wEvent, event, Holter, Pacemaker and INR services. The Company receives a significant portion of its revenue from third party commercial payors and governmental entities. It also receives reimbursement directly from patients through co-pay, deductibles and self-pay arrangements. | |||||||||||
        Revenue from the Medicare program is based on reimbursement rates set by CMS. Revenue from contracted commercial payors is recorded at the negotiated contractual rate. Revenue from non-contracted commercial payors is recorded at net realizable value based on historical payment patterns. Adjustments to the estimated net realizable value, based on final settlement with the third party payors, are recorded upon settlement. If the Company does not have consistent historical information regarding collectability from a given payor, revenue is recognized when cash is received. Unearned amounts are appropriately deferred until service is performed. For the years ended December 31, 2013, 2012 and 2011, revenue from Medicare as a percentage of total Company revenue was 35%, 37% and 33%, respectively. | |||||||||||
        Revenue received from the sale of products, product repair and supplies is recognized when shipped, or as service is completed. Unearned amounts are appropriately deferred until service is performed. | |||||||||||
        Research services revenue includes revenue for research and core laboratory services. The Company's research services revenues are provided on a fee for service basis, and revenue is recognized as the related services are performed. We also provide consulting services on a time and materials basis and recognize revenues as we perform the services. Our site support revenue, consisting of equipment rentals and sales along with related supplies and logistics management, are recognized at the time of sale or over the rental period. Under a typical contract, customers pay us a portion of our fee for these services upon contract execution as an upfront deposit, some of which is typically nonrefundable upon contract termination. Unearned revenues are deferred, and then recognized as the services are performed. | |||||||||||
        For arrangements with multiple deliverables, the revenue is allocated to each element (both delivered and undelivered items) based on their relative selling prices or management's best estimate of their selling prices, when vendor-specific or third-party evidence is unavailable. | |||||||||||
        We record reimbursements received for out-of-pocket expenses, including freight, incurred as revenue in the accompanying consolidated statements of operations. Revenue generally is recognized net of any taxes collected from customers and subsequently remitted to government authorities. | |||||||||||
Advertising Costs | ' | ||||||||||
Advertising Costs | |||||||||||
        Advertising costs are charged to expense as incurred. For the years ended December 31, 2013, 2012 and 2011, the Company incurred advertising costs of $223, $174 and $218, respectively. | |||||||||||

Basic net loss per share is computed by dividing net loss per share available to common shareholders by the weighted average number of common shares outstanding for the period, and excludes the effects of any potentially dilutive securities. Diluted earnings per share, if presented, would include the dilution that would occur upon the exercise or conversion of all potentially dilutive securities into common stock using the treasury stock or if converted methods, as applicable. | |||||||||||

Stock-Based Compensation | ' | ||||||||||
Stock-Based Compensation | |||||||||||
        ASC 718, Compensation—Stock Compensation, addresses the accounting for share-based payment transactions in which an enterprise receives employee services in exchange for (a) equity instruments of the enterprise or (b) liabilities that are based on the fair value of the enterprise's equity instruments or that may be settled by the issuance of such equity instruments. ASC 718 requires that an entity measures the cost of equity-based service awards based on the grant-date fair value of the award and recognizes the cost of such awards over the period during which the employee is required to provide service in exchange for the award (the vesting period). ASC 718 requires that an entity measures the cost of liability-based service awards based on current fair value that is re-measured subsequently at each reporting date through the settlement date. The Company accounts for equity awards issued to non-employees in accordance with ASC 505-50, Equity-Based Payments to Non-Employees. | |||||||||||
Income Taxes | ' | ||||||||||
Income Taxes | |||||||||||
        The Company accounts for income taxes under the liability method, as described in ASC 740, Income Taxes. Deferred income taxes are recognized for the tax consequences of temporary differences between the tax and financial statement reporting bases of assets and liabilities. A valuation allowance for net deferred tax assets is provided unless realizability is judged by the Company to be more likely than not. | |||||||||||
Segment Information | ' | ||||||||||
Segment Information | |||||||||||
        ASC 280, Segment Reporting, establishes standards for reporting information regarding operating segments in annual financial statements. Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision-maker, or decision-making group in making decisions on how to allocate resources and assess performance. | |||||||||||
        Effective in the third quarter 2012, with the acquisition of Cardiocore, the Company changed its reportable segments from two segments: patient services and product, to three segments: patient services, product and research services. The patient services business segment's principal focus is on the diagnosis and monitoring of cardiac arrhythmias or heart rhythm disorders, through its core Mobile Cardiac Outpatient TelemetryTM (MCOTTM), wEvent, event, Holter and Pacemaker services, as well as INR services in a healthcare setting. The Product business segment focuses on the development, manufacturing, testing and marketing of medical devices to medical companies, clinics and hospitals. The Research services segment includes the Company's operations that engage in central core laboratory services in a research environment, which includes certain equipment rental and product sales. In addition, the Company realigned the Product segment to exclude central core laboratory research operations previously reported in this segment and repositioned these operations into the Research services segment. Disclosures for the twelve months ended December 31, 2012 have been adjusted to reflect the change in reportable segments. | |||||||||||

Recent Accounting Pronouncements | |||||||||||
        In July 2012, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2012-02, Intangibles—Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment. The new guidance allows an entity the option to first assess qualitative factors to determine whether the existence of events and circumstances indicate that it is more likely than not that the indefinite-lived intangible asset is impaired. If the qualitative assessment leads to the determination that is more likely than not that the indefinite-lived intangible asset is impaired, then the entity is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. The ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The amendment did not have a material impact on the Company's results of operations, cash flows, or financial position. | |||||||||||
        In February 2013, FASB issued ASU 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. The new guidance requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The ASU is effective prospectively for reporting periods beginning after December 15, 2012. The amendment did not have a material impact on the Company's results of operations, cash flows, or financial position. | |||||||||||
        In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. The new guidance provides specific financial statement presentation requirements of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance states that an unrecognized tax benefit in those circumstances should be presented as a reduction to the deferred tax asset. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The Company does not expect the amendment to have a material impact on its results of operations, cash flows, or financial position. | |||||||||||
