Accounting Policies [Abstract]

Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported consolidated statements of operations during the reporting period. Actual results could differ from those estimates.

Principles of Consolidation

The accompanying financial statements include the accounts of MiMedx Group, Inc. and its wholly-owned subsidiaries MiMedx, Inc., MiMedx Processing Services, LLC (formerly known as SpineMedica, LLC), MiMedx Tissue Services, LLC (formerly known as Surgical Biologics, LLC) and Stability Biologics, LLC (formerly known as Stability Inc.). All significant inter-company balances and transactions have been eliminated.

Segment Reporting

ASC 280, “Segment Reporting” requires use of the “management approach” model for segment reporting. The management approach model is based on the way a company’s management organizes segments within the company for making operating decisions and assessing performance. The Company has determined it has one operating segment. Disaggregation of the Company’s operating results is impracticable, because the Company’s research and development activities and its assets overlap, and management reviews its business as a single operating segment. Thus, discrete financial information is not available for more than one operating segment.

Market Concentrations and Credit Risk

The Company places its cash and cash equivalents on deposit with financial institutions in the United States. In July 2010, the Federal Deposit Insurance Corporation (“FDIC”) increased coverage to $250,000 for substantially all depository accounts. As of December 31, 2016 and 2015, the Company had cash and cash equivalents of approximately $33,200,000 and $27,700,000, respectively, in excess of the insured amounts.

Cash and Cash Equivalents

Cash and cash equivalents include cash and FDIC insured certificates of deposit held at various banks with an original maturity of three months or less.

Accounts Receivable

Accounts receivable represent amounts due from customers for which revenue has been recognized. Generally, the Company does not require collateral or any other security to support its receivables.

The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses in the Company's existing receivables. The Company determines the allowance based on factors such as historical collection experience, customers' current creditworthiness, customer concentrations, age of accounts receivable balance and general economic conditions that may affect the customers' ability to pay.

Inventories

Inventories are valued at the lower of cost or market, using the first–in, first-out (FIFO) method. Inventory is tracked through Raw Material, WIP, and Finished Good stages as the product progresses through various production steps and stocking locations. Labor and overhead costs are absorbed through the various production processes up to when the work order closes. Historical yields and normal capacities are utilized in the calculation of production overhead rates. Reserves for inventory obsolescence are utilized to account for slow-moving inventory as well as inventory no longer needed due to diminished market demand.

Goodwill and Purchased Intangible Assets

Goodwill and purchased intangible assets with indefinite useful lives are not amortized but are tested for impairment at least annually. The Company reviews goodwill and purchased intangible assets with indefinite lives for impairment annually at the beginning of its fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. Potential impairment indicators include a significant change in the business climate, legal factors, operating performance indicators, competition, and the sale of disposition of a significant portion of the business. The Company first assesses certain qualitative factors to determine whether the existence of events or circumstances would indicate that it is more likely than not that the fair value of the Company was less than its carrying amount. If after assessing the totality of events or circumstances, the Company were to determine that it is more likely than not that the fair value of the Company is less than its carrying amount, then the Company would perform a two-step quantitative impairment testing. In the first step, the Company compares the fair value of the Company to its carrying value. The Company determines the fair value utilizing the market approach. Under the market approach, the Company uses its market capitalization which is calculated by taking the Company’s share price times the number of outstanding shares. If the fair value of the Company exceeds the carrying value of the net assets, goodwill is not impaired, and no further testing is required. If the fair value of the Company is less than the carrying value, the Company must perform the second step of the impairment test to measure the amount of impairment loss, if any. In the second step, the Company’s value is allocated to all of the assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of goodwill in the same manner as if the Company was being acquired in a business combination. If the implied fair value of the reporting unit's goodwill is less than the carrying value, the difference is recorded as an impairment loss. The Company has determined that there are no goodwill and indefinite useful lives intangible impairments in 2016 and 2015.

Impairment of Intangible Assets with Finite Lives

The Company reviews purchased intangible assets with finite lives for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable using a two-step impairment test. In step one, we determine the sum of the undiscounted future cash flows of the assets based on management's estimates and compare it to the carrying value of the assets. If the carrying amount is greater than the sum of the undiscounted cash flows, then the asset is impaired and step two is required. In step two, the impairment loss is calculated as the difference between the fair value of the assets and the carrying value of the assets.

Impairment reviews are based on an estimated future cash flow approach that requires significant judgment with respect to future revenue and expense growth rates, selection of appropriate discount rate, asset groupings, and other assumptions and estimates. The Company uses estimates that are consistent with our business plans and a market participant view of the assets being evaluated. Actual results may differ from our estimates. The Company has determined that there are no intangible assets with finite lives impairments in 2016 and 2015.

Property and Equipment

Property and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives, principally three to seven years. Leasehold improvements are depreciated on a straight-line basis over the lesser of the estimated useful lives or the life of the lease. The Company is party to various lease arrangements for its facility space and equipment. These arrangements include interest, scheduled rent increases and rent holidays which are included in the determination of minimum lease payments when assessing lease classification, and are included in rent expense on a straight line basis over the lease term. See Notes 7 and 16 for further information regarding capital leases, operating leases and rent expense.

Patent Costs

The Company incurs certain legal and related costs in connection with patent applications for tissue based products and processes. The Company capitalizes such costs to be amortized over the expected life of the patent to the extent that an economic benefit is anticipated from the resulting patent or alternative future use is available to the Company. The Company capitalized approximately $842,000 of patent costs during 2016, $851,000 of patent costs during 2015 and $594,000 of patent costs during 2014.

Impairment of Long-lived Assets

The Company evaluates the recoverability of its long-lived assets (property and equipment) whenever adverse events or changes in business climate indicate that the expected undiscounted future cash flows from the related assets may be less than previously anticipated. If the net book value of the related assets exceeds the expected undiscounted future cash flows of the assets, the carrying amount would be reduced to the present value of their expected future cash flows and an impairment loss would be recognized.

Revenue Recognition

The Company sells its products through a combination of a direct sales force, independent stocking distributors and third - party representatives in the U.S. and independent distributors in international markets. The Company recognizes revenue when title to the goods and risk of loss transfers to customers, provided there are no material remaining performance obligations required of the Company or any matters of customer acceptance. The Company records revenues from sales to our independent stocking distributors at the time the product is shipped to the distributor. Our stocking distributors, who sell the products to their customers or sub-distributors, contractually take title to the products and assume all risks of ownership at the time of shipment. Our stocking distributors are obligated to pay us the contractually agreed upon invoice price within specified terms regardless of when, if ever, they sell the products. Our stocking distributors do not have any contractual rights of return or exchange other than for defective product or shipping error; however, in limited situations, we do accept returns or exchanges at our discretion.

Some of the Company’s sales to Government accounts, including the Department of Veterans Affairs, are made through a distributor relationship with AvKARE, which is a veteran-owned General Services Administration Federal Supply Schedule (FSS) contractor. The Company's agreement with AvKARE expires, subject to certain for-cause termination rights, on June 30, 2017. The Company may also elect to terminate the agreement without cause and pay a termination fee to AvKARE as specified in the agreement. Upon termination of the agreement, the parties may mutually agree to extend the agreement or the Company has an obligation to repurchase AvKARE’s remaining inventory, if any, within ninety (90) days in accordance with the terms of the Agreement. At the end of the term, the parties expect AvKARE’s inventory to be minimal, based upon AvKARE's obligation to use commercially reasonable efforts to achieve target sales levels over the remaining term of the agreement.

We continually evaluate new and current customers, including our stocking distributors, for collectability based on various factors including past history with the customer, evaluation of their credit worthiness, and current economic conditions. We only record revenue when collectability is reasonably assured. A portion of the Company’s revenue is generated from inventory maintained at hospitals or physician's offices.

We make estimates of potential future sales returns, discounts and allowances related to current period product revenue and these are reflected as a reduction of revenue in the same period revenue is recognized. We base our estimate for sales returns, discounts and allowances on historical sales and product return information, including historical experience and actual and projected trend information as well as projected sales returns based on estimated usage and contractual arrangements with AvKARE. These estimates have historically been consistent with actual results.

Research and Development Costs

Research and development costs consist of direct and indirect costs associated with the development of the Company’s technologies. These costs are expensed as incurred.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, we determine deferred tax assets and liabilities on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

The Company recognizes deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company records uncertain tax positions in accordance with ASC 740 on the basis of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

Share-based Compensation

The Company accounts for its share- based compensation plans in accordance with FASB ASC topic 718 “Compensation- Stock compensation”. FASB ASC 718 requires the measurement and recognition of compensation expense for all share-based awards made to employees and directors, including employee stock options, restricted stock and warrants. Under the provisions of FASB ASC 718, and U. S. Securities and Exchange Commission Staff Accounting Bulleting No. 107, share-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense on a straight line basis over the requisite service period of the entire award (generally the vesting period of the award).

Fair Value of Financial Instruments

The respective carrying value of certain on-balance-sheet financial instruments approximated their fair values due to the short-term nature and type of these instruments. These financial instruments include cash and cash equivalents, accounts receivable, short term investments, accounts payable and accrued expenses. The carrying cost of the Company’s investments also reflects their fair values due to the type of these investments and the fair value of capital leases approximates their carrying value based upon current rates available to the Company.

Fair Value Measurements

The Company records certain financial instruments at fair value, including: cash equivalents, short term investments and investments. The Company may make an irrevocable election to measure other financial instruments at fair value on an instrument-by-instrument basis; although as of December 31, 2016, the Company has not chosen to make any such elections. Fair value financial instruments are recorded in accordance with the fair value measurement framework.

The Company also measures certain non-financial assets at fair value on a non-recurring basis. These non-recurring valuations include evaluating assets such as long-lived assets, and non-amortizing intangible assets for impairment; allocating value to assets in an acquired asset group, and accounting for business combinations. The Company uses the fair value measurement framework to value these assets and reports these fair values in the periods in which they are recorded or written down.

The fair value measurement framework includes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair values in their broad levels. These levels from highest to lowest priority are as follows:


•	Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities;


•	Level 2: Quoted prices in active markets for similar assets or liabilities or observable prices that are based on inputs not quoted on active markets, but corroborated by market data.


•	Level 3: Unobservable inputs or valuation techniques that are used when little or no market data is available.

The determination of fair value and the assessment of a measurement’s placement within the hierarchy require judgment. Level 3 valuations often involve a higher degree of judgment and complexity. Level 3 valuations may require the use of various cost, market, or income valuation methodologies applied to unobservable management estimates and assumptions. Management’s assumptions could vary depending on the asset or liability valued and the valuation method used. Such assumptions could include: estimates of prices, earnings, costs, actions of market participants, market factors, or the weighting of various valuation methods. The Company may also engage external advisors to assist it in determining fair value, as appropriate.

In connection with the acquisition of Stablity, the Company recorded a liability related to the Earn-Out portion of the purchase consideration. See Note 4, Acquisition, for further discussion of the Earn-Out liability. The Company has classified the Earn-Out liability as a Level 3 liability and the fair value of the Earn-Out liability will be evaluated each reporting period and changes in its fair value will be included in the Company’s results of operations. The fair value of the Earn-Out liability was calculated using a discount rate, approximating the pre-tax cost of debt and corroborated by Monte Carlo simulation, which was then applied to estimated earn out payments. To determine the fair value of the Earn-Out liability, management evaluates assumptions that require significant judgment. Changes in certain inputs to the valuation model, including the Company’s estimate of future revenues, can have a significant impact on the estimated fair value. The fair value recorded for the Earn-Out liability may vary significantly from period to period. This variability may result in the actual liability for a period either above or below the estimates recorded in the Company’s Consolidated Financial Statements, resulting in significant fluctuations in results of operations as a result of the corresponding non-cash gain or loss recorded.

Although the Company believes that the recorded fair value of its financial instruments is appropriate, these fair values may not be indicative of net realizable value or reflective of future fair values.

Recently Issued Accounting Pronouncements

The Company considers the applicability and impact of all Accounting Standards Updates ("ASUs"). In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, “Revenue Recognition - Revenue from Contracts with Customers” (ASU 2014-09) that requires companies to recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and rewards of a good or service. This update is effective for annual reporting periods beginning on or after December 15, 2017 and interim periods therein and requires expanded disclosures. The Company is currently assessing the impact the adoption of ASU 2014-09 will have on its consolidated financial statements.

In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments, that eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. ASU 2015-16 is effective for public companies for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The Company has adopted this standard in the first quarter of 2016 and its application is shown in Note 4.

In November 2015, the FASB issued ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes. ASU 2015-17 simplifies the presentation of deferred taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. ASU 2015-17 is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. The guidance may be adopted prospectively or retrospectively and early adoption is permitted. The Company has adopted this standard, prospectively, at the beginning of the fourth quarter 2015 to simplify reporting with the release of the valuation allowance as disclosed in Note 12. Prior periods were not retrospectively adjusted.

In February 2016, the FASB issued Accounting Standards Update ASU No. 2016-02, Leases (Topic 842). The core principle of Topic 842 is that a lessee should recognize the assets and liabilities that arise from leases. ASU 2016-02 is effective for public companies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years. The guidance may be adopted prospectively or retrospectively and early adoption is permitted. The Company is currently assessing the impact the adoption of ASU 2016-02 will have on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, "Compensation - Stock Compensation (Topic 718)". The standard is

intended to simplify several areas of accounting for share - based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. This ASU is effective for fiscal years beginning after December 15, 2016. The Company is currently assessing the impact the adoption of ASU 2016-09 will have on its consolidated financial statements. As of December 31, 2016, the Company does not have any remaining deferred tax assets that will result in an increase to equity upon realization. See Note 12.

In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments”. The update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This ASU is effective for public business entities for fiscal years beginning after December 15, 2017 and for interim periods within those fiscal years. The amendments in this update may be applied retrospectively or prospectively and early adoption is permitted. The Company is currently assessing the impact of the adoption of ASU 2016-15 will have on its consolidated financial statements.

All other ASUs issued and not yet effective for the year ended December 31, 2016, and through the date of this report, were assessed and determined to be either not applicable or are expected to have minimal impact on the Company's financial position or results of operations.

Acquisition of Stability Inc.

12 Months Ended

Dec. 31, 2016

Business Combinations [Abstract]

Acquisition of Stability Inc.

On January 13, 2016, the Company completed the acquisition of Stability Inc., d/b/a Stability Biologics ("Stability"), a provider of human tissue products to surgeons, facilities, and distributors serving the surgical, spine, and orthopedic sectors of the healthcare industry. As a result of this transaction, the Company acquired all of the outstanding shares of Stability in exchange for

$6,000,000 cash, $3,346,000 in stock, represented by 441,009 shares of our common stock, and assumed debt of $1,771,000. Additional one time costs incurred in connection with the transaction totaled $1,088,000 and are included within selling, general and administrative expenses on the consolidated statements of operations. Contingent consideration may be payable in a formula determined by sales less certain expenses for the years 2016 and 2017. The contingent consideration was valued at $17,450,000 as of December 31, 2016 and is shown in the schedule below as fair value of earn-out. The Company used a third party specialist to assist us with the valuation. The purchase price allocation figures should be attributed to the Company and not to the third party valuation firm. The contingent consideration was classified as a liability.

The Company has evaluated the contingent consideration for accounting purposes under GAAP and has determined that the contingent consideration is within the scope of ASC 480 "Distinguishing Liabilities from Equity" whereby a financial instrument, other than an outstanding share, that embodies a conditional obligation that the issuer may settle by issuing a variable number of its equity shares shall be classified as a liability if, at inception, the monetary value of the obligation is based solely or

predominantly on variations in something other than the fair value of the issuer’s equity shares.

The actual purchase price was based on cash paid, the fair value of our stock on the date of the acquisition, and direct costs

associated with the acquisition. The fair value of stock consideration was determined as set forth below:



Common Share Price at Closing on 1/13/2016		$	8.43
Multiplied by: Number of Common Shares Transferred to the Sellers		441,009
Indicated Value of Equity Consideration (on a Freely Tradable Interest Basis)		$	3,717,706
Less: Marketability Discount @ 10%	[a]	(371,771		)
Fair Value of Equity Consideration Transferred		$	3,345,935
[a] Shares transferred to the Sellers are restricted securities pursuant to Rule 144. As such, the Sellers are prevented from selling the shares for a period of six months. In addition, they are subject to contractual lockups which restrict sales for up to twelve months following the closing of the transaction.

The actual purchase price has been allocated as follows (in thousands):



Cash paid at closing	$	6,000
Working capital adjustment	(480		)
Common stock issued (441,009 shares)	3,346
Assumed debt	1,771
Fair value of earn-out	17,450
Total fair value of purchase price	$	28,087

Net assets acquired:
Debt-free working capital	$	2,456
Other long-term assets	199
Property, plant and equipment	1,375
Deferred tax liability	(5,896		)
Subtotal	(1,866		)
Intangible assets:
Customer relationships	5,330
Patents and know-how	6,790
Trade names and trademarks	450
Non compete agreements	830
Licenses and permits	390
Subtotal	13,790
Goodwill	16,163
Total Assets Purchased	$	28,087

Working capital and other assets were composed of the following (in thousands):
Working capital
Cash	$	140
Prepaid Expenses and other current assets	100
Accounts receivable	2,001
Federal and state taxes receivable	28
Inventory	9,002
Accounts payable and accrued expenses	(8,815		)
Debt-free working capital	$	2,456

Current portion of long term debt	$	(194	)
Long-term debt	(560		)
Line of Credit	(932		)
Shareholder loan	(85		)
Assumed debt	$	(1,771	)

Net working capital	$	685

The acquisition was accounted for as a purchase business combination as defined by FASB Topic 805 - "Business Combinations". The fair value of the contingent consideration is measured as a Level 3 instrument. The contingent consideration liability is recorded at fair value on the acquisition date. Increases or decreases in the fair value of contingent consideration can result from changes in anticipated revenue levels and changes in assumed discount periods and rates. As the fair value measured is based on significant inputs that are not observable in the market, they are categorized as Level 3. The income valuation approach was applied in determining the fair value of the contingent consideration using a discounted cash flow valuation technique with significant unobservable inputs comprised of projected sales and certain expenses. The values assigned to intangible assets are subject to amortization. The intangible assets were assigned the following lives for amortization purposes:



		Estimated useful life (in years)
Intangible asset:
Customer relationships		12
Patents and know-how		20
Trade name and Trademarks		Indefinite
Non compete agreements		4
Licenses and permits		2

Goodwill consists of the excess of the purchase price paid over the identifiable net assets and liabilities acquired at fair value. Goodwill is attributable to the assembled workforce of Stability and the synergies expected to arise following the acquisition. Goodwill is not expected to be deductible for tax purposes. Goodwill was determined using the residual method based on an independent appraisal of the assets and liabilities acquired in the transaction. Goodwill is tested for impairment on an annual basis as defined by FASB Topic 350 - "Intangibles - Goodwill and Other".

Goodwill reconciliation (in thousands):



Balance at 3/31/16	$	22,912
Goodwill Adjustments (a)	(6,749		)
Balance at 12/31/16	$	16,163
(a) Goodwill is the result of a residual calculation

The changes in the preliminary fair values of the acquired assets and liabilities were due to adjustments made to the prospective financial information ("PFI") to better reflect an expected case from a market participant's perspective. As the earn-out is limited to the gross profit margin for the first two years after the acquisition, the adjustment to the PFI had a decreasing impact on the estimated fair value of the earn-out at the acquisition date, which resulted in a lower total purchase consideration and a reduction of the estimated fair value of the identifiable intangible assets.

During the measurement period, management determined that the initial PFI should be adjusted to better reflect an expected case from a market participant's perspective. At the time of the acquisition, management believed that certain of the acquired company's products had reached certain marketability milestones. Management subsequently concluded that these milestones had indeed not yet been achieved. Also, at the time of the acquisition Management believed that certain manufacturing processes were at standards aligned with our overall company standards. Management subsequently concluded that the standards required improvements. These factors have resulted in a lower revenue trajectory in the periods that apply to the earn-out thus reducing the fair value of the earn-out.

The measurement period adjustments are as follows (in thousands):



	Provisional Per			Measurement Period
	3/31/2016 Form 10Q			Adjustments 2016			Final

Cash paid at closing	$	6,000		$	—		$	6,000

Total Assets Purchased	$	36,257		$	(8,170	)	$	28,087

Pursuant to the terms of the earn-out arrangement, the Company will pay, for each of the years ending December 31, 2016 and 2017, an amount equal to one times the gross profit margin from (a) the net sales of Stability products sold by Stability's or the Company's sales personnel and (b) the net sales of Company products sold by Stability's sales personnel; provided, however, if the amount of such net sales for either earn-out period is less than $12 million, the earn-out amount will decrease to 0.5 times the gross profit margin for such earn-out period. The full details of the earn-out arrangement are set forth in the acquisition agreement which is filed as Exhibit 2.1 to the Company's Form 8-K filed on January 13, 2016.

The following unaudited pro forma summary financial information presents the consolidated results of operations for the Company as if the acquisition had occurred on January 1, 2015. The pro forma results are shown for illustrative purposes only and do not purport to be indicative of the results that would have been reported if the acquisition had occurred on the date indicated or indicative of the results that may occur in the future.

Unaudited pro forma information for the twelve months ended December 31, 2016 and 2015 (in thousands) is as follows:



	Years Ended December 31,
	2016	2015
Revenue	$245,563	$204,481

Net income	$12,611	$24,960

Income per share, fully diluted	$0.11	$0.22

The 2016 supplemental pro forma earnings were adjusted to exclude $1,088,000 of acquisition-related legal, audit and other

costs, net of tax. The 2015 supplemental pro forma earnings were adjusted to include $1,176,000 of amortization costs (net of tax) related to recorded intangible assets with defined useful lives, and $1,485,000 of inventory step-up charges (net of tax) as a result of the acquisition for comparability to 2016. The number of shares outstanding used in calculating the income per share for 2015 was adjusted to include 441,009 shares issued as part of the purchase price and assumed to be issued on January 1, 2015.

As the Company is managed and operates in one segment, and since Stability was merged with the Company's existing operations, the Company has determined that disaggregation of the Company's operating results to provide the amount of revenue and earnings for Stability since the acquisition date is impracticable.

- Definition

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

(a)

On January 29, 2007, the Company acquired a license from Shriners Hospitals for Children and University of South Florida Research Foundation, Inc. in the amount of $996,000. Within 30 days after the receipt by the Company of approval by the FDA allowing the sale of the first licensed product, the Company is required to pay an additional $200,000 to the licensor. Due to its contingent nature, this amount is not recorded as a liability. The Company will also be required to pay a royalty of 3% on all commercial sales revenue from the licensed products. The Company is also obligated to pay a $50,000 minimum annual royalty payment over the life of the license. As of December 31, 2016 the license had a remaining net book value of approximately $10,000.

(b)

On January 5, 2011, the Company acquired Surgical Biologics, LLC. As a result, the Company recorded intangible assets for Customer & Supplier Relationships of $3,761,000, Patents & Know-How of $7,690,000, Licenses of $13,000, Tradenames & Trademarks of $1,008,000 and In-Process Research & Development of $25,000. For the twelve months ended December 31, 2016, approximately $48,000 of costs associated with patents granted during the period were capitalized and included in Patents & Know-How subject to amortization over the life of the patents.

Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt Credit Facility On October 12, 2015, the Company and its subsidiaries entered into a Credit Agreement (the "Credit Agreement") with certain lenders and Bank of America, N.A., as administrative agent. The Credit Agreement establishes a senior secured revolving credit facility in favor of the Company with a maturity date of October 12, 2018 and an aggregate lender commitment of up to $50 million. The Credit Agreement also provides for an uncommitted incremental facility of up to $35 million, which can be exercised as one or more revolving commitment increases or new term loans, all subject to certain customary terms and conditions set forth in the Credit Agreement. The obligations of the Company under the Credit Agreement are guaranteed by the Company's subsidiaries. The obligations of the loan parties under the Credit Agreement and the other credit documents are secured by liens on and security interests in substantially all of the assets of each of the loan parties and a pledge of the equity interests of each subsidiary owned by a loan party, subject to certain customary exclusions. Borrowings under the facility will bear interest at LIBOR plus 1.5% to 2.25%. Fees paid in connection with the initiation of the credit facility totaled approximately $500,000. These deferred financing costs are being amortized to interest expense over the three-year life of the facility. The Credit Agreement contains customary representations, warranties, covenants, and events of default, including restrictions on certain payments of dividends by the Company. As of December 31, 2016, there were no outstanding revolving loans under the credit facility. As of December 31, 2016, the Company was in compliance with all covenants under the Credit Agreement.

Earnings Per Share [Abstract]

Net Income Per Share

Basic net income per common share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per common share is computed using the weighted-average number of common and dilutive common equivalent shares from stock options, warrants and restricted stock using the treasury stock method.

The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands except per share data):

A summary of the status of the Company’s unvested stock options as of December 31, 2016 is presented below:



Unvested Stock Options	Number of Shares		Weighted- Average Grant Date Fair Value
Unvested at January 1, 2016	3,067,935		$	3.81
Granted	—		$	—
Cancelled	(154,200	)	$	6.77
Vested	(2,041,582	)	$	3.61
Unvested at December 31, 2016	872,153		$	4.28

Total unrecognized compensation expense at December 31, 2016, was approximately $1,064,000 and will be charged to expense through June 2017.

The fair value of the options granted was estimated on the date of grant using the Black-Scholes-Merton option-pricing model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate. Expected volatilities are based on historical volatility of peer companies and other factors estimated over the expected term of the options. The term of employee options granted is derived using the “simplified method” which computes expected term as the midpoint between the weighted average time to vesting and the contractual maturity. The simplified method was used due to the Company’s lack of sufficient historical data to provide a reasonable basis upon which to estimate the expected term due to the limited period of time its equity shares have been publicly traded. The term for non-employee options is generally based upon the contractual term of the option. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term or contractual term as described.

The assumptions used in calculating the fair value of options granted using the Black-Scholes-Merton option-pricing model are set forth in the following table:



	Year ended December 31,
	2016		2015	2014
Expected volatility	—	%	54.35 - 58.14%	58.14 - 64.50%
Expected life (in years)	0		6	6
Expected dividend yield	—		—	—
Risk-free interest rate	0		1.51 - 1.68%	1.64 - 1.96%

The weighted-average grant date fair value for options granted during the years ended December 31, 2016, 2015 and 2014 were approximately $0.00, $5.15 and $4.18, respectively.

Restricted Stock Awards

Following is summary information for restricted stock awards for the year ended December 31, 2016. Shares vest over a one to three year period. As of December 31, 2016, there was approximately $21,905,000 of total unrecognized stock-based compensation related to time-based, non-vested restricted stock. That expense is expected to be recognized on a straight-line basis over a weighted-average period of 1.9 years.

Additionally, during the twelve months ended December 31, 2016, 43,344 shares of common stock valued at approximately $345,700 were issued under the 2006 Plan to a consultant in return for services performed, and is included in the table that follows.

Income taxes are based on estimates of the annual effective tax rate and evaluations of possible future events and transactions and may be subject to subsequent refinement or revision.

Certain items of income and expense are not reported in tax returns and financial statements in the same year. The tax effect of such temporary differences is reported as deferred income taxes. The measurement of deferred tax assets is reduced, if necessary, by the amount of any tax benefit that, based on available evidence, is not expected to be realized. The Company establishes a valuation allowance for deferred tax assets for which realization is not likely. As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets.

As of December 31, 2016, our deferred tax assets were primarily the result of accrued liabilities, equity compensation, tax credits and net operating loss carryforwards. A valuation allowance of $554,000 and $782,000 was recorded against our gross deferred tax asset balance as of December 31, 2016, and December 31, 2015, respectively.

At December 31, 2016, the Company had income tax net operating loss ("NOL") carryforwards for federal and state purposes of $2,327,000 and $27,912,000 respectively. At December 31, 2015, the Company has income tax net operating loss ("NOL") carryforwards for federal and state purposes of $579,000 and $27,552,000 respectively. As of December 31, 2016, the Company has recorded a deferred tax asset for both federal and state NOL carryforwards of approximately $815,000 and approximately $1,580,000, respectively. As of December 31, 2015, the Company has recorded a deferred tax asset for both federal and state NOL carryforwards of approximately $197,000 and approximately $1,566,000, respectively. The Company's net operating losses and tax credits are subject to annual limitations due to ownership change limitations provided by Internal Revenue Code Section 382. If not utilized, the federal and state tax loss carryforwards will expire between 2027 and 2035. A valuation allowance remains recorded against the deferred tax asset for certain state net operating loss carryovers in the amount of $554,000 that are not expected to be utilized prior to expiration.

As a result of certain realization requirements of ASC 718, Compensation - Stock Compensation, the table of deferred tax assets and liabilities shown above does not include certain deferred tax assets that arose directly from (or the use of which was postponed by) tax deductions related to equity compensation that were greater than the compensation recognized for financial reporting. During 2016, deferred tax assets in the amount of $1,170,000 were realized resulting in an increase to equity in the same amount. As of December 31, 2016, the Company does not have any remaining deferred tax assets that will result in an increase to equity upon realization. The Company uses ASC 740 ordering when determining when excess tax benefits have been realized.

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits (in thousands):



	December 31, 2016		December 31, 2015
Unrecognized tax benefits - January 1	$	170	$	—

Gross increases - tax positions in current period	111		170

Unrecognized tax benefits - December 31	$	281	$	170

Included in the balance of unrecognized tax benefits as of December 31, 2016 and December 31, 2015, are $281,000 and $170,000, respectively, of tax benefits that, if recognized, would affect the effective tax rate. Also included in the balance of unrecognized tax benefits as of December 31, 2016 and December 31, 2015, are $281,000 and $170,000, respectively, of tax benefits that, if recognized, would result in adjustments to other tax accounts, primarily deferred taxes. This amount is recorded in Other Liabilities in the accompanying consolidated balance sheets.

The Company recognizes interest accrued related to unrecognized tax benefits and penalties as income tax expense. Related to the unrecognized tax benefits noted above, the Company accrued no penalties or interest during 2016, and, in total, as of December 31, 2016 has not recognized any liabilities for penalties or interest. During 2015, we also did not accrue any penalties or interest and, in total, as of December 31, 2015, had not recognized any liability for penalties or interest.

The Company is subject to taxation in the US and various state jurisdictions. As of December 31, 2016 the Company’s tax returns for 2013, 2014 and 2015 are subject to examination by the tax authorities. As of December 31, 2016, the Company is generally no longer subject to US federal, state, or local examinations by tax authorities for years before 2013.

FDA Untitled Letter, Draft Guidance and Related Litigation

FDA Untitled Letter and Draft Guidance

On August 28, 2013, the FDA issued an Untitled Letter alleging that the Company's micronized allografts do not meet the criteria for regulation solely under Section 361 of the Public Health Service Act and that, as a result, MiMedx would need a biologics license to lawfully market those micronized products. Since the issuance of the Untitled Letter, the Company has been in discussions with the FDA to communicate its disagreement with the FDA's assertion that the Company's allografts are more than minimally manipulated. To date, the FDA has not changed its position that the Company's micronized products are not eligible for marketing solely under Section 361 of the Public Health Service Act. The Company continues to market its micronized products but is also pursuing the Biologics License Application (“BLA”) process for certain of its micronized products.

On December 22, 2014, the FDA issued for comment “Draft Guidance for Industry and FDA Staff: Minimal Manipulation of Human Cells, Tissues, and Cellular and Tissue-Based Products.” Essentially the Minimal Manipulation draft guidance takes the same position with respect to micronized amniotic tissue that it took in the Untitled Letter to MiMedx 16 months earlier. The Company submitted comments asserting that the Minimal Manipulation draft guidance represents agency action that goes far beyond the FDA’s statutory authority, is inconsistent with existing HCT/P regulations and the FDA’s prior positions, and is internally inconsistent and scientifically unsound.

On October 28, 2015, the FDA issued for comment, "Draft Guidance for Industry and FDA Staff: Homologous Use of Human Cells, Tissues, and Cellular and Tissue-Based Products." The Company submitted comments on this Homologous Use draft guidance as well. On September 12 and 13, 2016, the FDA held a public hearing to obtain input on the Homologous Use draft guidance and the previously released Minimal Manipulation draft guidance, as well as other recently issued guidance documents on HCT/Ps. The Company awaits further decision from FDA on the draft guidances, but anticipates this will be a lengthy process.

If the FDA does allow the Company to continue to market a micronized form of its sheet allografts without a biologics license either prior to or after finalization of the draft guidance documents, it may impose conditions, such as labeling restrictions and compliance with cGMP. Although the Company is preparing for these requirements in connection with its pursuit of a BLA for certain of its micronized products, earlier compliance with these conditions requires significant additional time and cost investments by the Company. It is also possible that the FDA will not allow the Company to market any form of a micronized product without a biologics license even prior to finalization of the draft guidance documents and could even require the Company to recall its micronized products. Revenues from micronized products comprised approximately 10% of the Company's revenues in 2016.

Securities Class Action

Following the publication of the Untitled Letter from the FDA regarding the Company’s micronized products in September 2013, the trading price of the Company’s stock declined and several putative shareholder class action lawsuits were filed against the Company and certain of its executive officers asserting violations of the Securities Exchange Act of 1934. The cases were consolidated in the United States District Court for the Northern District of Georgia. On November 17, 2015, the parties entered into a stipulation of settlement to settle the consolidated case in its entirety. The stipulation of settlement was filed with the Court on November 18, 2015. On November 19, 2015, the Court preliminarily approved the settlement and confirmed the settlement on April 5, 2016. The settlement amount was paid by the Company's insurance carrier.

Former Employee Litigation

On December 13, 2016, the Company filed lawsuits against former employees Jess Kruchoski (in the lawsuit styled MiMedx Group, Inc. v. Academy Medical, LLC, et. al. in the County Court of the Fifteenth Judicial Circuit in and for Palm Beach County, Florida (the “Florida Action”)) and Luke Tornquist (in the lawsuit styled MiMedx Group, Inc., v. Luke Tornquist in the Superior Court for Cobb County, Georgia, which was removed to the United States District Court for the Northern District of Georgia (the “Georgia Action”)). Both the Florida and Georgia Actions assert claims against Messrs. Kruchoski and Tornquist that each of them violated their restrictive covenants entered into with the Company, that each of them misappropriated trade secrets of the Company, that each of them tortiously interfered with contracts between the Company and its customers and employees, and that each of them breached his duty of loyalty owed to the Company, among other claims.

On December 15, 2016, Messrs. Kruchoski and Tornquist filed a lawsuit in the United States District Court of Minnesota (the “Minnesota Action”) against the Company and the Company’s Chairman and Chief Executive Officer, Parker Petit. The plaintiffs in this lawsuit each claimed that their employment with the Company was terminated in retaliation for their complaints about the Company’s alleged business practices in violation of the Dodd-Frank Act, 15 U.S.C. § 78u-6(h); and was an unlawful discharge in violation of Minnesota Statutes Section 181.931 subdivision 1. Mr. Kruchoski also claimed that the termination of his employment with the Company constituted marital status discrimination and familial status discrimination in violation of the Minnesota Human Rights Act. Messrs. Kruchoski and Tornquist also claimed that Mr. Petit tortiously interfered with their employment relationships with the Company.

On January 26, 2017, the Company and Mr. Petit filed motions to dismiss the Minnesota Action. In response, Messrs. Kruchoski and Tornquist voluntarily dismissed the Minnesota Action without prejudice on February 7, 2017. On February 7, 2017, Mr. Tornquist filed his Answer and Counterclaims in the Georgia Action wherein he asserted claims similar to those he had asserted in the Minnesota Action, with the exception that he did not include a claim of tortious interference against Mr. Petit. On February 15, 2017, Mr. Kruchoski filed a new lawsuit in Georgia against MiMedx and Mr. Petit, making many of the same allegations in that suit as were made in the Minnesota suit, with the addition of claims against the Company and Mr. Petit for defamation.

The Company intends to vigorously pursue its claims asserted in the Florida and Georgia Actions and also to vigorously defend against the lawsuits and counterclaims asserted against them.

Patent Litigation

MiMedx continues to diligently enforce its intellectual property against several entities. Currently, there are four actions pending, as described below:

The Liventa Action

On April 22, 2014, the Company filed a patent infringement lawsuit in the United States District Court for the Northern District of Georgia against Liventa Bioscience, Inc. ("Liventa"), Medline Industries, Inc. ("Medline") and Musculoskeletal Transplant Foundation, Inc. ("MTF") for permanent injunctive relief and unspecified damages (the "Liventa Action"). In addition to the allegations of infringement of MiMedx's patents, the lawsuit asserts that Liventa and Medline knowingly and willfully made false and misleading representations about their respective products to providers, patients, and in some cases, prospective investors. Though the terms of the agreement are confidential, the parties have reached a settlement of the false advertising claims for an undisclosed sum. The patent infringement claims are still pending as described below.

MiMedx asserts that Liventa (formerly known as AFCell Medical, Inc.), Medline and MTF infringed and continue to infringe certain of the Company's patents relating to the MiMedx dehydrated human amnion/chorion membrane ("dHACM") allografts. MTF is the tissue processor while Liventa and Medline are the distributors of the allegedly infringing products. On May 30, 2014, defendants filed answers to the Complaint, denying the allegations in the Complaint. They also raised affirmative defenses of non-infringement, invalidity, laches and estoppel. MTF and Medline also filed counterclaims seeking declaratory judgments of non-infringement and invalidity. Defendants filed parallel Inter Partes Review ("IPR") proceedings which are discussed below. We expect the case to go to trial in 2017.

The Bone Bank Action

On May 16, 2014, the Company also filed a patent infringement lawsuit against Transplant Technology, Inc. d/b/a Bone Bank Allografts ("Bone Bank") and Texas Human Biologics, Ltd. ("Biologics") for permanent injunctive relief and unspecified damages (the "Bone Bank Action"). The Bone Bank Action was filed in the United States District Court for the Western District of Texas. This lawsuit similarly asserts that Bone Bank and Biologics infringed certain of the Company's patents through the manufacturing and sale of their placental-derived tissue graft products. On July 10, 2014, Defendants filed an answer to the Complaint, denying the allegations in the Complaint. They also raised affirmative defenses of non-infringement and invalidity and filed counterclaims seeking declaratory judgments of non-infringement and invalidity. Defendants also filed parallel IPR proceedings which are further discussed below. Discovery is closed and we expect the case to go to trial in 2017.

The NuTech Action

On March 2, 2015, the Company filed a patent infringement lawsuit against NuTech Medical, Inc. ("NuTech") and DCI Donor Services, Inc. ("DCI") for permanent injunctive relief and unspecified damages. This lawsuit was filed in the United States District Court for the Northern District of Alabama. The lawsuit alleges that NuTech and DCI have infringed and continue to infringe the Company's patents through the manufacture, use, sale, and/or offering of their tissue graft product. The lawsuit also asserts that NuTech knowingly and willfully made false and misleading representations about its products to customers and/or prospective customers. The case is currently in the discovery phase.

The Vivex Action

On April 1, 2016, the Company also filed a patent infringement lawsuit against Vivex BioMedical (“Vivex”) for permanent injunctive relief and unspecified damages (the "Vivex Action"). The lawsuit was filed in the United States District Court for the Northern District of Georgia. The patent at issue is the 8,709,494 patent (the "494" patent). Vivex answered the Company’s complaint and filed counterclaims of non-infringement and invalidity. On January 4, 2017, the Court granted a joint motion to stay the proceedings pending the outcome of the Bone Bank Action.

Pending IPRs

In addition to defending the claims in the pending district court litigations, defendants in the Liventa and Bone Bank cases have challenged certain of the Company's patents in several IPR proceedings to avoid the high burden of proof of proving invalidity by "clear and convincing evidence" in the district court litigations. An inter partes review (or "IPR") is a request for a specialized group within the United States Patent and Trademark Office to review the validity of a plaintiff's patent claims. The defendants in the Bone Bank Action challenged the validity of the Company's 8,597,687 (the "687" patent) and the '494 patent; while the defendants in the Liventa Action challenged the validity of the Company's 8,372,437 and 8,323,701 patents (the "'437" and "'701" patents, respectively).

On June 29, 2015, the Patent Trial and Appeals Board ("PTAB") denied the Bone Bank defendants' request for institution of an IPR with respect to the '494 patent (EpiFix) on all seven challenged grounds. On August 18, 2015, the PTAB also denied the Liventa defendants' request for institution of an IPR with respect to the '701 patent (AmnioFix) on all six challenged grounds. That is, the PTAB decided in each case that the defendants failed to establish a reasonable likelihood that defendants would prevail in showing any of the challenged claims of the '494 or the '701 patent were unpatentable.

On July 10, 2015, the PTAB issued an opinion allowing a review of the '687 patent to proceed, although on only two of the five challenged grounds. On July 7, 2016, the PTAB issued an opinion finding that the challenged claims, which relate to embossment and not configuration, were invalid for obviousness. The Company decided not to appeal the decision, as it impacted a non-core patent. On August 18, 2015, the PTAB issued an opinion allowing a review of the '437 patent to proceed, although only on one of the seven challenged grounds. On August 16, 2016, the PTAB issued an opinion finding that the challenged claims were unpatentable. MiMedx has filed an appeal of the PTAB’s decision regarding the '437 patent.
