Principles of Consolidation

The consolidated financial statements include the accounts of the Company and all wholly owned organizations. All intercompany transactions and account balances have been eliminated in consolidation.

Segments

The Company operates in one business segment based on management's view of its business for purposes of evaluating performance and making operating decisions, representing the only reportable segment in accordance with Accounting Standard Codification ("ASC") 280, "Segment Reporting."

The Company utilizes shared services including but not limited to, human resources, payroll, finance, sales, pump repair and maintenance services, as well as certain shared assets and sales, general and administrative costs. The Company is in the process of transitioning more shared services and synergies since the acquisition of First Biomedical. The Company's approach is to make operational decisions and assess performance based on delivering products and services that together provide solutions to our customer base, utilizing functional management structure and shared services where possible. Based upon this business model, the chief operating decision maker only reviews consolidated financial information.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements, including the notes thereto. The Company considers critical accounting policies to be those that require more significant judgments and estimates in the preparation of its consolidated financial statements. These include the following: revenue recognition, which includes contractual adjustments, accounts receivable and allowance for doubtful accounts, sales return allowances, inventory reserves, income taxes and goodwill and other intangibles valuation. Management relies on historical experience and other assumptions believed to be reasonable in making its judgment and estimates. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company maintains its cash and cash equivalents primarily with two financial institutions and is fully insured with the Federal Deposit Insurance Corporation (FDIC) under the Temporary Liquidity Guarantee Program until December 31, 2012.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are reported at the estimated net realizable amounts from patients, third-party payors and other direct pay customers for goods provided and services rendered. The Company performs periodic analyses to assess the accounts receivable balances. It records an allowance for doubtful accounts based on the estimated collectability of the accounts such that the recorded amounts reflect estimated net realizable value. Upon determination that an account is uncollectible, the account is written-off and charged to the allowance.

Accounts receivable are reduced by an allowance for amounts that could become uncollectible in the future. The Company's estimate for its allowance for doubtful accounts is based upon management's assessment of historical and expected net collections by payer. Due to continuing changes in the health care industry and third-party reimbursement it is possible that management's estimates could change in the near term, which could have an impact on its financial position, results of operations, and cash flows.

Inventory

Our inventory consists of infusion pumps and related parts and supplies and is stated at the lower of cost, determined on a first in, first out basis, or market. The Company periodically performs an analysis of slow moving inventory and records a reserve based on estimated obsolete inventory.

Property and Equipment

Property and equipment is stated at acquired cost and depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to seven years. Rental equipment, consisting primarily of infusion pumps that the Company acquires from third-parties, is depreciated over five years. Information Technology (IT) software and hardware are depreciated over three years. Leasehold improvements are amortized using the straight-line method over the life of the asset or the remaining term of the lease, whichever is shorter. Maintenance and minor repairs are charged to operations as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is recorded in the current period.

Long-Lived Assets

The Company accounts for the impairment and disposition of long-lived assets in accordance with ASC 360, "Property, Plant and Equipment." This standard addresses financial accounting and reporting for the impairment of long-lived assets and for the disposal of long-lived assets. In accordance with this standard, long-lived assets to be held are reviewed for events or changes in circumstances, which indicate that their carrying value may not be recoverable. If an impairment indicator exists, the Company assesses the asset or asset group for recoverability. Recoverability of these assets is determined based upon the expected undiscounted future net cash flows from the operations to which the assets relate, utilizing management's best estimates, appropriate assumptions and projections at the time. If the carrying value is determined not to be recoverable from future operating cash flows, the asset is deemed impaired and an impairment loss would be recognized to the extent the carrying value exceeded the estimated fair market value of the asset. The Company reviews the carrying value of long-lived assets if there is an indicator of impairment. As described below, the Company performed an impairment analysis on all of its assets and determined that there was no impairment of property, plant and equipment as of June 30, 2011.

Goodwill Valuation

Goodwill arising from business combinations represents the excess of the purchase price over the estimated fair value of the net assets of the businesses acquired.

In accordance with the provisions of ASC 350, "Intangibles — Goodwill and Other," goodwill is tested annually for impairment or more frequently if circumstances indicate the possibility of impairment. Significant judgments required to estimate fair value include estimating future cash flows, and determining appropriate discount rates, growth rates and other assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value which could trigger impairment. The Company performed the annual impairment test at October 31, 2010, and determined there was no impairment of goodwill.

As of June 30, 2011, the Company determined that there may be market conditions relating to the stock price, elimination of warrants, and business forecasts to conclude that the carrying value of our single reporting unit exceeds the fair market value, and therefore could indicate impairment of goodwill. As a result of the triggering events, the Company performed an impairment test of goodwill as of June 30, 2011 and concluded that impairment of goodwill exists. For more information, refer to the "Goodwill and Intangible Assets" discussion included in Note 5.

Intangible Assets

Intangible assets consist of trade names, physician and customer relationships, non-compete agreements, and software. The trade names, physician and customer relationships and non-compete agreements arose from the acquisitions of InfuSystem and First Biomedical. The Company amortizes the value assigned to the physician and customer relationships on a straight-line basis over the period of expected benefit, which is 15 years. The acquired physician and customer relationship base represents a valuable asset of InfuSystem due to the expectation of future business opportunities to be leveraged from the existing relationship with each physician and customer. InfuSystem has long-standing relationships with numerous oncology clinics, physicians, home care and home infusion providers, skilled nursing facilities, pain centers and others. These relationships are expected, on average, to have a 15 year useful life, based on minimal attrition experienced to date by the Company and expectations of continued minimal attrition. Non-compete agreements are amortized on a straight-line basis over five years and software is amortized on a straight-line basis over three years. Management tests non-amortizable intangible assets (i.e., trade names such as InfuSystem) for impairment in accordance with ASC 350. The Company performed the annual impairment test at October 31, 2010, and determined there was no impairment.

As of June 30, 2011, the Company determined that there may be market conditions relating to the stock price, elimination of warrants, and business forecasts to conclude that there may be impairment of the Company's indefinite lived intangibles relating to tradenames. As a result, the Company performed an impairment test of its indefinite lived intangibles as of June 30, 2011 and concluded that there is impairment of its tradenames. For more information, refer to the "Goodwill and Intangible Assets" discussion included in Note 5.

Accumulated Other Comprehensive Loss

Accumulated other comprehensive loss consists only of the unrealized loss on the single interest rate swap in place as of June 30, 2011, net of taxes. For more information on the interest rate swap, refer to Note 6. During the three months ended June 30, 2011, there was a comprehensive loss of $163 thousand related to unrealized loss on the swap. The tax impact was $82 thousand leaving a net accumulated other comprehensive loss of $81 thousand. During the six months ended June 30, 2011, there was a comprehensive loss of $96 thousand related to the unrealized loss on the swap. The tax impact on the loss was $62 thousand, leaving a net accumulated other comprehensive loss of $98 thousand as reflected in the Company's consolidated balance sheet as of June 30, 2011. The following table summarizes comprehensive loss for the applicable periods (in thousands):

Revenue Recognition

The majority of the Company's revenue is rental revenue in the oncology market. Revenues are recognized predominantly under fee for service arrangements through equipment that the Company rents to patients. The Company recognizes revenue only when all of the following criteria are met: 1) persuasive evidence of an arrangement exists, 2) services have been rendered, 3) the price to the customer is fixed or determinable and 4) collectability is reasonably assured. Persuasive evidence of an arrangement is determined to

exist, and collectability is reasonably assured, when the Company receives 1) a physician's written order and assignment of benefits, signed by the physician and patient, respectively, and the Company has 2) verified actual pump usage and 3) insurance coverage. The Company recognizes rental revenue from electronic infusion pumps as earned, normally on a month-to-month basis. Pump rentals are billed at the Company's established rates, which often differ from contractually allowable rates provided by third-party payors such as Medicare, Medicaid and commercial insurance carriers. All billings to third party payors are recorded net of provision for contractual adjustments to arrive at net revenues.

Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenues and accounts receivable at their net realizable values. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payors may result in adjustments to amounts originally recorded. Due to continuing changes in the health care industry and third-party reimbursement, it is possible that management's estimates could change in the near term, which could have an impact on our results of operations and cash flows.

The Company's largest payor is Medicare, which accounted for approximately 32% and 31% of its gross billings for the six months ended June 30, 2011 and 2010, respectively. The Company has contracts with various individual Blue Cross/Blue Shield affiliates which in the aggregate accounted for approximately 21% and 23% of its gross billings for the six months ended June 30, 2011 and 2010, respectively. No individual payor (other than Medicare and the Blue Cross/Blue Shield entities) accounts for greater than approximately 6% of the Company's gross billings.

The Company recognizes revenue for selling, renting and servicing new and pre-owned infusion pumps and other medical equipment to oncology practices as well as other alternate site settings including home care and home infusion providers, skilled nursing facilities, pain centers and others when 1) persuasive evidence of an arrangement exists, 2) services have been rendered, 3) the price to the customer is fixed or determinable and 4) collectability is reasonably assured. The Company performs an analysis to estimate sales returns and record an allowance. This estimate is based on historical sales returns.

Income Taxes

The Company accounts for income taxes in accordance with ASC 740, "Income Taxes," which requires that the Company recognize deferred tax liabilities and assets based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities, using enacted tax rates in effect in the years the differences are expected to reverse. Deferred income tax (expense) benefit results from the change in net deferred tax assets or deferred tax liabilities. A valuation allowance is recorded when, in the opinion of management, it is more likely than not that some or all of any deferred tax assets will not be realized. For more information, refer to the "Income Taxes" discussion included in Note 8.

Share Based Payment

ASC 718, "Stock Compensation," requires all entities to recognize compensation expense in an amount equal to the fair value of share based payments made to employees, among other requirements. Under the fair value based method, compensation cost is measured at the grant date based on the fair value of the award and is recognized on a straight-line basis over the award vesting period. Accordingly, share based payments issued to officers and directors are measured at fair value and recognized as expense over the related vesting periods.

In 2007, the Company adopted the 2007 Stock Incentive Plan (the "Plan") providing for the issuance of a maximum of 2,000,000 shares of common stock in connection with the grant of stock-based or stock-denominated awards. In addition, the Company has made certain grants of restricted stock outside of the Plan.

Share based compensation expense recognized for the three and six months ended June 30, 2011 was $254 thousand and $502 thousand, respectively, compared to $897 thousand and $997 thousand for the three and six months ended June 30, 2010, respectively.

Warrants and Derivative Financial Instruments

On April 18, 2006, the Company consummated its initial public offering ("IPO") of 16,666,667 units. Each unit consists of one share of common stock and two redeemable common stock purchase warrants. Each warrant entitles the holder to purchase from the Company one share of its common stock at an exercise price of $5.00.

The Warrant Agreement provides for the Company to register the shares underlying the warrants in the absence of the Company's ability to deliver registered shares to the warrant holders upon warrant exercise.

ASC 815 requires freestanding derivative contracts that are settled in a company's own stock, including common stock warrants, to be designated as equity instruments, assets or liabilities. Under the provisions of this standard, a contract designated as an asset or a liability must be carried at its fair value on a company's balance sheet, with any changes in fair value recorded in the company's results of operations. A contract designated as an equity instrument must be included within equity, and no fair value adjustments are required from period to period.

The 8,329,638 remaining warrants issued in connection with the IPO and overallotment to purchase common stock expired on April 11, 2011 and the Company recorded a realized gain of $83 thousand, which is included on the gain in derivatives line item on the income statement, during the quarter ended June 30 2011.

ASC 815 requires that an entity recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value.

Cash Flow Hedge

The Company is exposed to risks associated with future cash flows related to the variability of the interest rate on its term loan with Bank of America. In order to manage the exposure of these risks, the Company enters into interest rate swaps. On July 20, 2010, the Company entered into a single interest rate swap and designated the swap as a cash flow hedge. In accordance with ASC 815, the fair value of the swap is shown on the Company's consolidated balance sheet within derivative liabilities, unrealized changes in the fair value are included in accumulated other comprehensive loss within the stockholders' equity section on the Company's consolidated balance sheet, and any realized changes would be included in the Company's consolidated statement of operations within interest expense.

Deferred Debt Issuance Costs

Capitalized debt issuance costs as of June 30, 2011 and December 31, 2010 relate solely to the Company's Bank of America credit facility. The Company classifies the costs related to the Bank of America credit facility as non-current assets and amortizes them using the interest method through the maturity date of June 2014. For a further discussion of the Company's deferred debt issuance costs, see Note 7.

Earnings Per Share

Basic loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted loss per share assumes the issuance of potentially dilutive shares of common stock during the period. The following table reconciles the numerators and denominators of the basic and diluted loss per share computations:

For the three and six months ended June 30, 2011 the following stock awards were not included in the calculation because they would have an anti-dilutive effect: 130,479 in stock options and 2,138,750 in unvested restricted shares. For the three and six months ended June 30, 2010 the following warrants and stock awards were not included in the calculation because they would have an anti-dilutive effect: 8,329,638 outstanding warrants issued in connection with the IPO, 1,142,858 warrants issued privately, and 100,479 in vested stock options.

Subsequent events

The Company adopted the provisions of ASC 855, "Subsequent Events" effective June 15, 2009 and management has concluded that there are no significant subsequent events requiring disclosure as of the date the consolidated financial statements.
