Accounting Policies [Abstract]

Basis of Presentation

1.	Basis of Presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S.”) (“GAAP”) and, in the opinion of management, reflect all adjustments, consisting of normal recurring adjustments, needed to fairly present the financial results of SurModics, Inc. and subsidiaries (“SurModics” or the “Company”) for the periods presented. These financial statements include some amounts that are based on management’s best estimates and judgments. These estimates may be adjusted as more information becomes available, and any adjustment could be significant. The impact of any change in estimates is included in the determination of net income in the period in which the change in estimate is identified. The results of operations for the three and six months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the entire 2015 fiscal year.

In accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”), the Company has omitted footnote disclosures that would substantially duplicate the disclosures contained in the audited financial statements of the Company. These unaudited condensed consolidated financial statements should be read together with the audited consolidated financial statements for the fiscal year ended September 30, 2014, and footnotes thereto included in the Company’s Form 10-K as filed with the SEC on December 5, 2014.

Revenue recognition

The Company recognizes revenue when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) shipment has occurred or delivery has occurred if the terms specify destination; (3) the sales price is fixed or determinable; and (4) collectability is reasonably assured. When there are additional performance requirements, revenue is recognized when all such requirements have been satisfied. Under revenue arrangements with multiple deliverables, the Company recognizes each separable deliverable as it is earned.

The Company derives its revenue from three primary sources: (1) royalties and license fees from licensing its proprietary drug delivery and surface modification technologies and in vitro diagnostic formats to customers; (2) the sale of reagent chemicals to licensees and the sale of stabilization products, antigens, substrates and surface coatings to the diagnostic and biomedical research markets; and (3) research and commercial development fees generated on customer projects.

Royalties and license fees. The Company licenses technology to third parties and collects royalties. Royalty revenue is generated when a customer sells products incorporating the Company’s licensed technologies. Royalty revenue is recognized as licensees report it to the Company, and payment is typically submitted concurrently with the report. For stand-alone license agreements, up-front license fees are recognized over the term of the related licensing agreement. Minimum royalty fees are recognized in the period earned.

Revenue related to a performance milestone is recognized upon the achievement of the milestone, as defined in the respective agreements and provided the following conditions have been met:

•

The milestone payment is non-refundable;

•

The milestone involved a significant degree of risk, and was not reasonably assured at the inception of the arrangement;

•

Accomplishment of the milestone involved substantial effort;

•

The amount of the milestone payment is commensurate with the related effort and risk; and

•

A reasonable amount of time passed between the initial license payment and the first and subsequent milestone payments.

If these conditions have not been met, the milestone payment is deferred and recognized over the term of the agreement.

Product sales. Product sales to third parties consist of direct and distributor sales and are recognized at the time of shipment. The Company’s sales terms provide no right of return outside of the standard warranty policy. Payment terms are generally set at 30-45 days.

Research and development. The Company performs third-party research and development activities, which are typically provided on a time and materials basis. Generally, revenue for research and development is recorded as performance progresses under the applicable contract.

Arrangements with multiple deliverables. Revenue arrangements with multiple deliverables require the Company to:

(i) disclose whether multiple deliverables exist, how the deliverables in an arrangement should be separated, and how the consideration should be allocated;

(ii) allocate revenue in an arrangement using estimated selling prices (“ESP”) of deliverables if a vendor does not have vendor-specific objective evidence of selling price (“VSOE”) or third-party evidence of selling price (“TPE”); and

(iii) allocate revenue using the relative selling price method.

The Company accounts for revenue using a multiple attribution model in which consideration allocated to research and development activities is recognized as performed, and milestone payments are recognized when the milestone events are achieved, when such activities and milestones are deemed substantive. Accordingly, in situations where a unit of accounting includes both a license and research and development activities, and when a license does not have stand-alone value, the Company applies a multiple attribution model in which consideration allocated to the license is recognized ratably, consideration allocated to research and development activities is recognized as performed and milestone payments are recognized when the milestone events are achieved, when such activities and milestones are deemed substantive.

The Company enters into license and development arrangements that may consist of multiple deliverables which could include a license(s) to SurModics’ technology, research and development activities, manufacturing services, and product sales based on the needs of its customers. For example, a customer may enter into an arrangement to obtain a license to SurModics’ intellectual property which may also include research and development activities, and supply of products manufactured by SurModics. For these services provided by SurModics, SurModics could receive upfront license fees upon signing of an agreement and granting the license, fees for research and development activities as such activities are performed, milestone payments contingent upon advancement of the product through development and clinical stages to successful commercialization, fees for manufacturing services and supply of product, and royalty payments based on customer sales of product incorporating SurModics’ technology. The Company’s license and development arrangements generally do not have refund provisions if the customer cancels or terminates the agreement. Typically all payments made are non-refundable.

The Company is required to evaluate each deliverable in a multiple element arrangement for separability. The Company is then required to allocate revenue to each separate deliverable using a hierarchy of VSOE, TPE, or ESP. In many instances, the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be a result of the Company infrequently selling each element separately or having a limited history with multiple element arrangements. When VSOE cannot be established, the Company attempts to establish a selling price of each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately.

When the Company is unable to establish a selling price using VSOE or TPE, the Company uses ESP in its allocation of arrangement consideration. The objective of ESP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. ESP is generally used for highly customized offerings.

The Company determines ESP for undelivered elements by considering multiple factors including, but not limited to, market conditions, competitive landscape and past pricing arrangements with similar features. The determination of ESP is made through consultation with the Company’s management, taking into consideration the marketing strategies for each business unit.

New Accounting Pronouncements

Accounting Standards to be Adopted

In May 2014, the Financial Accounting Standards Board (“FASB”) issued new revenue recognition guidance for recognizing revenue from contracts with customers that provides a five-step analysis of transactions to determine when and how revenue is recognized. The guidance states that a Company should recognize revenue which depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to receive in exchange for those goods or services. The new standard will also result in enhanced disclosures about revenue related to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The standard also requires quantitative and qualitative disclosures about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. Additionally, the FASB has provided guidance for transactions that were not previously addressed comprehensively, and improved guidance for multiple-element arrangements. This pronouncement is effective for the Company beginning in fiscal 2018 (October 1, 2017), early adoption is not permitted, and can be adopted by the Company either retrospectively (October 1, 2015) or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the impact that the adoption of this new accounting guidance will have on the Company’s results of operations, cash flows and financial position.

On April 1, 2015 the FASB decided to propose a one-year deferral of the effective date for the revenue recognition standard. Under this proposal the guidance would be effective for the Company beginning in fiscal 2019 (October 1, 2018). As of May 5, 2015 this proposal is not yet approved and final.

No other new accounting pronouncement issued or effective has had, or is expected to have, a material impact on the Company’s consolidated financial statements.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

4.	Fair Value Measurements

The accounting guidance on fair value measurements defines fair value, establishes a framework for measuring fair value under GAAP, and expands disclosures about fair value measurements. The guidance is applicable for all financial assets and financial liabilities and for all nonfinancial assets and nonfinancial liabilities recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually). Fair value is defined as the exchange price that would be received from selling an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions and risk of nonperformance.

Fair Value Hierarchy

Accounting guidance on fair value measurements requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1 — Quoted (unadjusted) prices in active markets for identical assets or liabilities.

The Company’s Level 1 assets consisted of its investment in Intersect ENT, Inc. (“Intersect ENT”) and certain U.S. government and government agency obligations. The fair market value of the Intersect ENT investment was based on the quoted price of Intersect ENT shares as traded on the NASDAQ Global Market Stock Exchange. This investment was sold in the second quarter of fiscal 2015 generating a realized gain of $0.5 million. The fair market value of certain U.S. government and government agency obligations were based on observable prices in highly active treasury and agency security markets for identical securities.

Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

The Company’s Level 2 assets consist of money market funds, commercial paper instruments, certain U.S. Treasury securities, corporate bonds, municipal bonds, certain U.S. government agency securities, government agency and municipal securities and certain asset-backed and mortgage-backed securities. Fair market values for these assets are based on quoted vendor prices and broker pricing where all significant inputs are observable. The Company performs limited tests of the quoted vendor prices based on available U.S. government security pricing on government websites as a means of validating the third party pricing. To ensure the accuracy of quoted vendor prices and broker pricing, the Company performs regular reviews of investment returns to industry benchmarks and sample tests of individual securities to validate quoted vendor prices with other available market data.

Level 3 — Unobservable inputs to the valuation methodology that are supported by little or no market activity and that are significant to the measurement of the fair value of the assets or liabilities. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, as well as significant management judgment or estimation.

There were no Level 3 assets at March 31, 2015 and 2014 or September 30, 2014 and there was no Level 3 activity during the first six months of fiscal 2015 or fiscal 2014.

In valuing assets and liabilities, the Company is required to maximize the use of quoted market prices and minimize the use of unobservable inputs. The Company changed its valuation techniques from prior periods in the first quarter of fiscal 2015 to classify certain U.S. government and government agency obligations as Level 1 based on observable prices in highly active treasury and agency security markets for identical securities.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

In instances where the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. The following table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2015:


*(Dollars in thousands)*	Quoted Prices in Active Markets for Identical Instruments (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total Fair Value as of March 31, 2015

Corporate bonds		—		1,830		—		1,830

Total assets measured at fair value	$	1,550	$	58,413	$	—	$	59,963

Valuation Techniques

The valuation techniques used to measure the fair value of assets are as follows:

Cash equivalents — These assets are classified as Level 2 and are carried at historical cost which is a reasonable estimate of fair value because of the relatively short time between origination of the instrument and its expected realization.

Available-for-sale debt securities — These securities are classified as Level 1 or Level 2 and include various types of debt securities. These securities are valued based on quoted vendor prices in highly active or active markets underlying the securities.

Investments, Debt and Equity Securities [Abstract]

Investments

5.	Investments

Investments consist principally of U.S. government and government agency obligations, mortgage-backed securities and corporate and municipal debt securities and are classified as available-for-sale at March 31, 2015 and September 30, 2014. Available-for-sale securities are reported at fair value with unrealized gains and losses, net of tax, excluded from the condensed consolidated statements of income and reported in the condensed consolidated statements of comprehensive income as well as a separate component of stockholders’ equity in the condensed consolidated balance sheets, except for other-than-temporary impairments, which are reported as a charge to current earnings. A loss would be recognized when there is an other-than-temporary impairment in the fair value of any individual security classified as available-for-sale, with the associated net unrealized loss reclassified out of accumulated other comprehensive income with a corresponding adjustment to other income. This adjustment results in a new cost basis for the investment. Interest earned on debt securities, including amortization of premiums and accretion of discounts, is included in other income. Realized gains and losses from the sales of debt securities, which are included in other income, are determined using the specific identification method.

The amortized cost, unrealized holding gains and losses, and fair value of available-for-sale securities as of March 31, 2015 and September 30, 2014 were as follows:


	March 31, 2015

Equity securities		2		1,548		—			1,550

Total	$	18,347	$	1,617	$	(101	)	$	19,863

As of September 30, 2014, the Company concluded that the unrealized losses related to the available-for-sale securities shown above were not other-than-temporary as the Company did not have the intent to sell, nor was it more likely than not that the Company would be required to sell, before recovery of their amortized cost. As of March 31, 2015 all available-for-sale debt securities were classified as current assets as the Company plans to liquidate its investment portfolio in the third quarter of fiscal 2015 to support corporate development initiatives. Unrealized losses as of March 31, 2015 were immaterial to the Company’s consolidated financial statements.

The amortized cost and fair value of available-for-sale debt securities, by contractual maturity, at March 31, 2015 were as follows:


*(Dollars in thousands)*	Amortized Cost		Fair Value

In February 2011, the stent technology of Nexeon MedSystems, Inc. (“Nexeon”) was acquired by CeloNova BioSciences, Inc. (“CeloNova”). Prior to the acquisition by CeloNova, Nexeon created a wholly-owned subsidiary, Nexeon Stent, to hold the company’s stent-related assets. Nexeon distributed to its stockholders the Nexeon Stent stock which was exchanged for Series B-1 preferred shares of CeloNova. CeloNova is a privately-held Texas-based medical technology company that is marketing a variety of medical products. The Company’s investment in CeloNova, which is accounted for under the cost method, represents less than a 2% ownership interest. The Company does not exert significant influence over CeloNova’s operating or financial activities.

The Company has invested a total of $5.3 million in ViaCyte, Inc. (“ViaCyte”), a privately-held California-based biotechnology firm that is developing a unique treatment for diabetes using coated islet cells, the cells that produce insulin in the human body. In fiscal 2006, the Company determined that its investment in ViaCyte was impaired and that the impairment was other-than-temporary. Accordingly, the Company recorded an impairment loss of $4.7 million. In the second quarter of fiscal 2013, the Company recorded an additional other-than-temporary impairment loss on this investment totaling $0.1 million based on a then current financing round and market valuations. The balance of the investment of $0.5 million, which is accounted for under the cost method, represents less than a 1% ownership interest. The Company does not exert significant influence over ViaCyte’s operating or financial activities.

The total carrying value of cost method investments is reviewed quarterly for changes in circumstances or the occurrence of events that suggest the Company’s investment may not be recoverable. The fair value of cost method investments is not adjusted if there are no identified events or changes in circumstances that may have a material adverse effect on the fair value of the investment.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill

9.	Goodwill

Goodwill represents the excess of the cost of an acquired entity over the fair value assigned to the assets purchased and liabilities assumed in connection with a business acquisition. Goodwill is not amortized but is subject, at a minimum, to annual tests for impairment in accordance with accounting guidance for goodwill. The carrying amount of goodwill is evaluated annually, and between annual evaluations if events occur or circumstances change indicating that the carrying amount of goodwill may be impaired.

The $8.0 million of goodwill at March 31, 2015 and September 30, 2014 is related to the In Vitro Diagnostics reporting unit and represents the gross value from the acquisition of BioFX Laboratories, Inc. (“BioFX”) in 2007. The goodwill was not impaired based on the outcome of the fiscal 2014 annual impairment test, and there have been no events or circumstances that have occurred in the first six months of fiscal 2015 associated with the In Vitro Diagnostics reporting unit to indicate that the goodwill has been impaired.

Stock-based Compensation

Stock-based Compensation

The Company has stock-based compensation plans under which it grants stock options, restricted stock awards, performance share awards, restricted stock units and deferred stock units. Accounting guidance requires all share-based payments to be recognized as an operating expense, based on their fair values, over the requisite service period.

The Company’s stock-based compensation expenses were allocated to the following expense categories:


	Three Months Ended March 31,				Six Months Ended March 31,
*(Dollars in thousands)*	2015		2014		2015		2014
Product costs	$	5	$	4	$	13	$	8
Research and development		54		46		114		98
Selling, general and administrative		627		1,599		1,084		2,356

Total	$	686	$	1,649	$	1,211	$	2,462

As of March 31, 2015, approximately $2.7 million of total unrecognized compensation costs related to non-vested awards is expected to be recognized over a weighted average period of approximately 2.2 years. The unrecognized compensation costs above include $0.4 million, remaining to be expensed over the life of the awards, based on payout levels associated with performance share awards that are currently anticipated to be fully expensed because the performance conditions are expected to exceed minimum threshold levels.

Stock Option Awards

The Company uses the Black-Scholes option pricing model to determine the weighted average grant date fair value of stock options granted. The weighted average per share fair values of stock options granted during the three months ended March 31, 2015 and 2014 were $8.72 and $7.61, respectively. The weighted average per share fair values of stock options granted during the six months ended March 31, 2015 and 2014 were $7.23 and $8.72, respectively. The assumptions used as inputs in the model were as follows:


	Three Months Ended						Six Months Ended
	March 31,						March 31,
	2015			2014			2015			2014
Risk-free interest rates		1.4	%		1.2	%		1.4	%		1.2	%
Expected life (years)		4.5			4.1			4.5			4.6
Expected volatility		43.2	%		37.1	%		43.3	%		44.5	%
Dividend yield		0.0	%		0.0	%		0.0	%		0.0	%

The risk-free interest rate assumption was based on the U.S. Treasury’s rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award. The expected life of options granted was determined based on the Company’s experience. Expected volatility was based on the Company’s stock price movement over a period approximating the expected term. Based on management’s judgment, dividend rates were expected to be zero for the expected life of the options. The Company also estimates forfeitures of options granted, which were based on historical experience.

Non-qualified stock options are granted at fair market value on the date of grant. Non-qualified stock options expire in seven to ten years or upon termination of employment or service as a Board member. With respect to members of our Board, non-qualified stock options generally become exercisable on a pro-rata basis within the one-year period following the date of grant. With respect to our employees, non-qualified stock options generally become exercisable with respect to 25% of the shares on each of the first four anniversaries following the grant date.

The total pre-tax intrinsic value of options exercised during the three months and six months ended March 31, 2015 was $1.2 million and $1.4 million, respectively. The total pre-tax intrinsic value of options exercised during the three months and six months ended March 31, 2014 was $0.9 million and $1.3 million, respectively. The intrinsic value represents the difference between the exercise price and the fair market value of the Company’s common stock on the last day of the respective fiscal period end.

The Company modified stock option awards granted to Board members in February 2014, which resulted in acceleration of the stock option vesting period. The modification changed the vesting period to pro-rata over a 12-month service period and resulted in an increase to stock option related expense of $0.6 million in the three and six months ended March 31, 2014.

Restricted Stock Awards

The Company has entered into restricted stock agreements with certain key employees, covering the issuance of common stock (“Restricted Stock”). Under accounting guidance these shares are considered to be non-vested shares. The Restricted Stock is released to the key employees if they are employed by the Company at the end of the vesting period. Compensation expense has been recognized for the estimated fair value of the common shares and is being recognized over the vesting term. The stock-based compensation table above includes Restricted Stock expenses recognized related to these awards, which totaled less than $0.1 million for the three months ended March 31, 2015, and $0.1 million for the six months ended March 31, 2015 and $0.2 million for each of the three and six months ended March 31, 2014. In February 2014, the Company granted an award of $0.2 million to the former Chairman of its Board of Directors in connection with his retirement from the Board and in recognition of his contributions to the Company during his years of service.

Performance Share Awards

The Company has entered into performance share agreements with certain key employees and executives, covering the issuance of common stock (“Performance Shares”). Performance Shares vest upon the achievement of all or a portion of certain performance objectives (which may include financial or project objectives), which must be achieved during the performance period. The Organization and Compensation Committee of the Board of Directors (the “Committee”) approves the performance objectives used for our executive compensation programs, which objectives were cumulative earnings per share and cumulative revenue for the three-year performance periods for fiscal 2012 (2012 – 2014), fiscal 2013 (2013 – 2015) and fiscal 2014 (2014 – 2016), and are cumulative revenue and cumulative EBITDA for fiscal 2015 (2015 – 2017). Assuming that the minimum performance level is attained, the number of shares that may actually vest will vary based on performance from 20% (minimum) to 200% (maximum) of the target number of shares. Shares will be issued to participants as soon as practicable following the end of the performance periods subject to Committee approval and verification of results. The fiscal 2012 awards were finalized in the three months ended December 31, 2014 and resulted in the issuance of 98,093 shares (maximum was 124,994 shares) based on the performance objectives and actual results. The compensation cost related to the number of shares to be granted under each performance period is fixed on the grant date. Compensation expense was recognized in each period based on management’s best estimate of the achievement level of actual and forecasted results, as appropriate, compared with the specified performance objectives for Performance Shares. For the three and six months ended March 31, 2015, the Company recognized expenses of $0.2 million and $0.3 million, respectively. For the three and six months ended March 31, 2014, the Company recognized expenses of $0.3 million and $0.5 million, respectively. The stock-based compensation table above includes the Performance Shares expenses.

The fair values of the Performance Shares, at target, were $0.9 million in each fiscal year for grants awarded in fiscal 2015, 2014 and 2013.

The aggregate number of shares that could be awarded to our executives if the minimum, target and maximum performance goals are met, based on the fair value at the date of grant is as follows:


Performance Period	Minimum Shares		Target Shares		Maximum Shares
Fiscal 2013 – 2015		8,551		42,753		85,506
Fiscal 2014 – 2016		7,861		39,303		78,606
Fiscal 2015 – 2017		8,440		42,199		84,398

1999 Employee Stock Purchase Plan

Under the 1999 Employee Stock Purchase Plan (“Stock Purchase Plan”), the Company is authorized to issue up to 400,000 shares of common stock. All full-time and part-time employees can choose to have up to 10% of their annual compensation withheld, with a limit of $25,000, to purchase the Company’s common stock at purchase prices defined within the provisions of the Stock Purchase Plan. As of March 31, 2015 and 2014, there was less than $0.1 million of employee contributions in each period included in accrued liabilities in the condensed consolidated balance sheets. Stock compensation expense recognized related to the Stock Purchase Plan for the three and six months ended March 31, 2015 and 2014 totaled less than $0.1 million in each period. The stock-based compensation table above includes the Stock Purchase Plan expenses.

Restricted Stock and Deferred Stock Units

In the six months ended March 31, 2015, the Company awarded 10,678 restricted stock units (“RSU”), and has cumulatively awarded 35,512 RSUs to non-employee directors since fiscal 2013 under the 2009 Equity Incentive Plan. There were forfeitures of 3,068 shares and issuances of 7,681 shares in the three and six months ended March 31, 2015 and forfeiture of 3,417 RSU’s and issuances of 2,183 shares of common stock to departed non-employee directors in fiscal 2014. The RSU awards vest on a pro-rata basis over a one-year period. RSU awards are not considered as issued or outstanding common stock of the Company until shares are issued to a non-employee director upon retirement from the Board of Directors. The estimated fair value of the RSU awards was determined based on the closing market price of SurModics’ common stock on the date of grant. Compensation expense has been recognized for the estimated fair value of the common shares and is being expensed over the vesting term. The stock-based compensation table above includes RSU expenses recognized related to these awards, which totaled less than $0.1 million and $0.1 million in the three and six months ended March 31, 2015, respectively, and $0.2 million and $0.3 million in the three and six months ended March 31, 2014, respectively. The RSU awards were modified in the second quarter of fiscal 2014 to vest pro-rata over a 12-month service period. This modification resulted in an additional expense of $0.2 million in the three and six months ended March 31, 2014.

Directors can also elect to receive their cash retainers for services to the Board of Directors and its committees in the form of deferred stock units (“DSU”). Certain directors elected this option beginning on January 1, 2013, with deferral elections made on an annual basis, which has resulted in 1,332 and 2,886 DSUs issued with a total value of less than $0.1 million and $0.1 million in the three and six months ended March 31, 2015, respectively. The DSUs are fully vested. The stock-based compensation table above includes DSU expenses recognized related to these awards, which totaled less than $0.1 million and $0.1 million during the three months and six months ended March 31, 2015, respectively, and less than $0.1 million and $0.1 million during the three and six months ended March 31, 2014, respectively.

Revolving Credit Facility

On November 4, 2013, the Company entered into a three-year $20.0 million secured revolving credit facility. The Company’s obligations under the credit facility are secured by substantially all of its and its subsidiaries’ assets, other than intellectual property and real estate. Borrowings under the credit facility, if any, will bear interest at a benchmark rate plus a margin ranging from 1.375% to 2.00% based on the Company’s leverage ratio. A facility fee is payable on unused commitments at a rate of 0.20% per annum.

On November 5, 2014, the credit facility was amended and modified to increase the size of stock repurchases that may be effected by the Company up to $30.0 million without the consent of the lender.

In connection with the credit facility, the Company is required to maintain financial covenants related to a maximum leverage ratio and a minimum EBITDA amount and to comply with nonfinancial covenants. As of March 31, 2015, the Company has no debt outstanding and was in compliance with all financial covenants.

Net Income Per Share Data

Net Income Per Share Data

Basic net income per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding during the period. The Company’s potentially dilutive common shares are those that result from dilutive common stock options, non-vested stock relating to restricted stock awards, restricted stock units, deferred stock units and performance shares.

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


	Three Months Ended March 31,				Six Months Ended March 31,
	2015		2014		2015		2014

Net income available to common shareholders	$	3,051	$	2,459	$	6,665	$	6,089


Basic weighted average shares outstanding		12,944		13,538		13,092		13,658
Dilutive effect of outstanding stock options, non-vested restricted stock, restricted stock units, deferred stock units and performance shares		263		286		273		267

Diluted weighted average shares outstanding		13,207		13,824		13,365		13,925

The calculation of weighted average diluted shares outstanding excludes outstanding stock options associated with the right to purchase 0.3 million and 0.2 million shares of common stock for the three months ended March 31, 2015 and 2014, respectively, and 0.5 million and 0.4 million for the six months ended March 31, 2015 and 2014, respectively, as their inclusion would have had an antidilutive effect on diluted net income per share.

On November 5, 2014, the Company’s Board of Directors authorized it to repurchase up to $30.0 million of the Company’s outstanding common stock in open-market purchases, privately negotiated transactions, block trades, accelerated share repurchase transactions, tender offers or by any combination of such methods. The authorization has no fixed expiration date. During the six months ended March 31, 2015, as part of the accelerated share repurchase program discussed below, the Company repurchased 758,143 shares of common stock for a total of $16.0 million under the $30.0 million November 2014 Board authorization and as of March 31, 2015, $14.0 million remained available for future repurchases under the current authorization. The $14.0 million includes $4.0 million of the initial payment to Wells Fargo in the first quarter of fiscal 2015 under the accelerated share repurchase program discussed below.

On November 11, 2014, the Company entered into an accelerated share repurchase program with Wells Fargo Bank, National Association. In connection with this agreement, the Company made an initial $20.0 million payment to the bank and immediately received an initial delivery of 758,143 shares of its common stock with a fair value of $16.0 million as of the purchase date. Effective as of the date of the initial share purchase, the transaction was accounted for as a share retirement, resulting in a reduction of common stock of less than $0.1 million, additional paid-in capital of $2.5 million and retained earnings of $13.5 million. The remaining $4.0 million of the Company’s initial payment was also reported as a reduction in retained earnings. Upon final settlement of the program, the Company may be entitled to receive additional shares of common stock, or, under certain circumstances specified in the program, the Company may be required to deliver shares or remit a settlement amount in cash, at the Company’s option. Based on the facts associated with the agreement, the forward contract is indexed to the Company’s common stock and meets the U.S. GAAP requirements to be classified as permanent equity. As long as the forward contract continues to meet the requirements to be classified as permanent equity, the Company will not record future changes in its fair value. The Company expects it will continue to meet those requirements through the settlement date.

The accelerated share repurchase program with Wells Fargo expires in the fourth quarter of fiscal 2015; however, Wells Fargo has the right to accelerate the end of the purchase period. Upon settlement of the contract, the Company will adjust common stock and either additional paid-in capital or retained earnings, as appropriate, to reflect the final settlement amount. The specific number of shares that the Company will ultimately purchase under the accelerated share purchase agreement will be based on the volume weighted average price (“VWAP”) of the Company’s common stock during the purchase period, less an agreed upon discount. The maximum amount of shares of common stock the Company can be required to issue to settle the agreement cannot exceed 1,870,907.

Income Taxes

The Company recorded income tax provisions associated with income from continuing operations of $1.5 million and $1.2 million for the three months ended March 31, 2015 and 2014, respectively, representing effective tax rates of 32.7% and 33.0%, respectively. The Company recorded income tax provisions associated with income from continuing operations of $3.0 million and $2.7 million for the six months ended March 31, 2015 and 2014, respectively, representing effective tax rates of 30.7% and 30.5%, respectively. The difference between the U.S. federal statutory tax rate of 35.0% and the Company’s effective tax rate for the three and six months ended March 31, 2015 and 2014 reflects the impact of state income taxes, permanent tax items such as valuation allowance releases associated with gains from our strategic investments and our available-for-sale securities portfolio and discrete tax benefits. Discrete tax benefits aggregated less than $0.1 million and $0.2 million for the three and six months ended March 31, 2015, respectively, and less than $0.1 million and $0.2 million for the three and six months ended March 31, 2014, respectively.

The discrete tax items in the fiscal 2015 six-month period includes a $0.2 million income tax benefit associated with the December 2014 signing of the Tax Increase Prevention Act of 2014 which retroactively reinstated the federal research and development income tax credit, which had expired in December 2013.

The three and six-month periods ended March 31, 2015 income tax provisions included the impact of a $0.5 million gain from the sale of Intersect ENT with an offsetting reversal of a capital loss carryforward valuation allowance. The six months ended March 31, 2014 income tax provision includes the impact of gains related to two Vessix Vascular, Inc. contingent consideration payments totaling $0.7 million and gains related to certain debt securities in our available-for-sale securities portfolio of $0.1 million. Each of these gains has had a tax expense recognized which has been fully offset by the reversal of capital loss carryforward valuation allowances.

The Company did not have any discontinued operations activity in the three and six months ended March 31, 2015 and 2014.

The total amount of unrecognized tax benefits, including interest and penalties that, if recognized, would affect the effective tax rate as of March 31, 2015 and September 30, 2014, was $0.9 million in each period. Currently, the Company does not expect the liability for unrecognized tax benefits to change significantly in the next 12 months with the above balances classified on the condensed consolidated balance sheets in other long-term liabilities. Interest and penalties related to unrecognized tax benefits are recorded in income tax expense.

The Company files income tax returns, including returns for its subsidiaries, in the U.S. federal jurisdiction and in various state jurisdictions. Uncertain tax positions are related to tax years that remain subject to examination. U.S. income tax returns for years prior to fiscal 2011 are no longer subject to examination by federal tax authorities. For tax returns for state and local jurisdictions, the Company is no longer subject to examination for tax years generally before fiscal 2004.

Segment Reporting [Abstract]

Operating Segment Information

Operating Segment Information

The accounting standards for reporting information about operating segments define operating segments as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, who is the Company’s Chief Executive Officer, in deciding how to allocate resources and in assessing performance. For financial accounting and reporting purposes, the Company reports its results for the two reportable segments as follows: (1) the Medical Device unit, which is comprised of surface modification coating technologies to improve access, deliverability, and predictable deployment of medical devices, as well as drug delivery coating technologies to provide site-specific drug delivery from the surface of a medical device, with end markets that include coronary, peripheral, neuro-vascular and urology, among others, and (2) the In Vitro Diagnostics unit, which consists of component products and technologies for diagnostic test kits and biomedical research applications, with products that include protein stabilization reagents, substrates, antigens and surface coatings.

The tables below present segment revenue, operating income and depreciation and amortization, as follows:


	Three Months Ended March 31,						Six Months Ended March 31,
*(Dollars in thousands)*	2015			2014			2015			2014

Total segment operating income		5,627			5,915			12,240			11,913
Corporate		(1,695	)		(2,435	)		(3,274	)		(4,104	)

Total operating income	$	3,932		$	3,480		$	8,966		$	7,809


Depreciation and amortization:
Medical Device	$	295		$	287		$	565		$	581
In Vitro Diagnostics		216			213			430			427
Corporate		195			184			394			372

Total depreciation and amortization	$	706		$	684		$	1,389		$	1,380

The Corporate category includes expenses for administrative corporate functions, such as executive, corporate accounting, legal, human resources and Board of Directors related, that have not been fully allocated to the Medical Device and In Vitro Diagnostics segments. Corporate may also include expenses, such as litigation, which are not specific to a segment and thus not allocated to the operating segments.

Asset information by operating segment is not presented because the Company does not provide its chief operating decision maker assets by operating segment, as the data is not readily available.

- Definition

The entire disclosure for reporting segments including data and tables. Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.

Commitments and Contingencies

Litigation. From time to time, the Company has been, and may become, involved in various legal actions involving its operations, products and technologies, including contract, intellectual property and employment disputes. The outcomes of these legal actions are not within the Company’s complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages, as well as other relief, including injunctions barring the sale of products that are the subject of the lawsuit, which, if granted, could require significant expenditures or result in lost revenue. The Company records a liability in the condensed consolidated financial statements for these actions when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate, the minimum amount of the range is accrued. If a loss is possible but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded.

During the second quarter of fiscal 2015, a customer notified the Company that it believes it overpaid approximately $5.7 million in hydrophilic coating royalties to the Company from January 2009 through September 2014. The customer also seeks interest on its alleged overpayments. In accordance with the underlying agreement between the Company and the customer, the Company has requested certain factual documentation from the customer related to the claim. The Company has recently received a portion of the requested documentation and is currently evaluating its sufficiency. In addition the remainder of the requested documentation has not yet been received. As of March 31, 2015, the Company has not recorded an accrual for this claim. Any potential loss is not estimable based on information available to the Company as of March 31, 2015 or subsequent to quarter end.

InnoRx, Inc. In January 2005, the Company entered into a merger agreement whereby SurModics acquired all of the assets of InnoRx, Inc. (“InnoRx”), an early stage company developing drug delivery devices and therapies for the ophthalmology market. SurModics will be required to issue up to approximately 480,059 additional shares of its common stock to the stockholders of InnoRx upon the successful completion of the remaining development and commercial milestones involving InnoRx technology acquired in the transaction. The Company has not recorded any accrual for this contingency as of March 31, 2015 as the milestones have not been achieved and the probability of achievement is low.

InnoCore Technologies BV. In March 2006, the Company entered into a license agreement whereby SurModics obtained an exclusive license to a drug delivery coating for licensed products within the vascular field which included peripheral, coronary and neurovascular biodurable stent products. The license requires an annual minimum payment of 200,000 euros (equivalent to $217,000 using a euro to US $ exchange rate of 1.08501 as of March 31, 2015) until the last patent expires which is currently estimated to be September 2027. The total minimum future payments associated with this license are approximately $2.7 million. The license is currently utilized with one of SurModics’ drug delivery customers.
