|Fair Value Disclosures [Text Block]||
Fair value is defined as the price that would be received upon selling an asset or the price paid to transfer a liability on the measurement date. It focuses on the exit price in the principal or most advantageous market for the asset or liability in an orderly transaction between willing market participants. A three-tier fair value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair values are as follows:
Goodwill and other indefinite-lived intangible assets are tested for impairment annually, at the end of the fourth quarter of each fiscal year, and between annual tests if an event occurs or circumstances change that would indicate it is more likely than not that the carrying amount may be impaired. Additionally, the Company continually evaluates whether events or changes in circumstances might indicate that the remaining estimated useful life of long-lived assets may warrant revision, or that the remaining balance may not be recoverable. The factors used to determine fair value are subject to management’s judgement and expertise and include, but are not limited to, the present value of future cash flows, net of estimated operating costs, internal forecasts, anticipated capital expenditures and various discount rates commensurate with the risk and current market conditions associated with realizing the expected cash flows projected. These assumptions represent Level 3 inputs. Impairment of the Company’s goodwill for the year ended December 31, 2017 was $10.3 million. Impairment of the Company’s goodwill and MIST Therapy tradename for the year ended December 31, 2016 was $10.9 million.
On December 31, 2016, the Company recomputed the fair value of its warrant liability of outstanding warrants to purchase an aggregate of 81,628 shares of common stock as $20,000 using the Binomial option pricing model (Level 3 inputs) using the following assumptions: expected volatility of 65.74%-72.16%, risk-free rate of 0.85%-1.47%, expected term of 0.86-3.41 years, and expected dividends of 0.00%. The Company recorded a gain on the change in fair value of these warrant liabilities of $841,000 during the year ended December 31, 2016.
The Company amended and restated the Warrant on each of October 25, 2016, January 26, 2017, March 7, 2017 and April 6, 2017. In addition, on June 1, 2017, the Company further amended the amended and restated Warrant. The amended and restated Warrant, as amended, is exercisable for 210,000 shares of the Company’s common stock at an exercise price of $4.70 per share. See Note 12 Debt for additional details. In connection with the amendments of January, March, April and June 2017, the Company recomputed the fair value of the original warrant and amended warrant using the Binomial option pricing model (Level 3 inputs) using the following assumptions: expected volatility of 65.33%-78.98%, risk-free rate of 1.49%-1.95%, expected term of 3.34-5.00 years, and expected dividends of 0.00%. As a result, the Company recorded warrant modification expense of $803,000 during the year ended December 31, 2017, which represents the incremental value of the amended warrant as compared to the original warrant, both valued as of the respective amendment dates.
On December 31, 2017, the Company recomputed the fair value of its warrant liability of outstanding warrants to purchase an aggregate of 210,000 shares of common stock as $130,000 using the Binomial option pricing model (Level 3 inputs) using the following assumptions: expected volatility of 73.37% risk-free rate of 2.09%, expected term of 4.07 years, and expected dividends of 0.00%. The Company recorded a gain on the change in fair value of these warrant liabilities of $692,000 during the year ended December 31, 2017.
The issuance of common stock in connection with the Private Placement and Public Offering triggered an adjustment to the exercise price of certain warrants originally issued in November 2012 from $55.10 per share to $5.00 per share to $4.00 per share with a corresponding adjustment to the number of shares underlying such warrants from 6,629 shares to 29,034 shares to 36,231 shares. The impact of such adjustment is included in the change in fair value of the warrant liabilities during the year ended December 31, 2017.
Warrants that contain exercise reset provisions and contingent consideration liabilities are Level 3 derivative liabilities measured at fair value on a recurring basis using pricing models for which at least one significant assumption is unobservable as defined in ASC 820. The fair value of contingent consideration liabilities that are classified as Level 3 were estimated using a discounted cash flow technique with significant inputs that are not observable in the market and thus represents a Level 3 fair value measurement as defined in ASC 820. The significant inputs in the Level 3 measurement not supported by market activity include the probability assessments of expected future cash flows related to the acquisitions, appropriately discounted considering the uncertainties associated with the obligation, and as calculated in accordance with the terms of the acquisition agreements. See Note 13 Commitments and Contingencies for details on the contingent consideration. The development and determination of the unobservable inputs for Level 3 fair value measurements and the fair value calculations are the responsibility of the Company’s Chief Financial Officer and are approved by the Chief Executive Officer.
The following table sets forth a summary of the changes in the fair value of Level 3 warrant liabilities and contingent consideration that are measured at fair value on a recurring basis (in thousands):
Assets and liabilities measured at fair value on a recurring basis are as follows (in thousands):
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.
