Notes to Condensed Consolidated Financial Statements

 

1.

Nature of Business

 

Alder BioPharmaceuticals, Inc. (the “Company”) is a clinical-stage biopharmaceutical company that discovers, develops and seeks to commercialize therapeutic antibodies with the potential to meaningfully transform the treatment paradigm in migraine. The Company has developed a proprietary antibody platform designed to select and manufacture antibodies that have the potential to maximize efficacy as well as speed of onset and durability of therapeutic response. The Company was incorporated in Delaware on May 20, 2002 and is located in Bothell, Washington.

Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements reflect the accounts of Alder BioPharmaceuticals, Inc. and its wholly-owned subsidiaries, Alder BioPharmaceuticals Pty. Ltd., AlderBio Holdings LLC, and Alder BioPharmaceuticals Limited. All inter-company balances and transactions have been eliminated in consolidation. The condensed consolidated balance sheet data as of December 31, 2017 were derived from audited financial statements. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and generally accepted accounting principles in the United States of America (“GAAP”) for unaudited condensed consolidated financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The accompanying unaudited condensed consolidated financial statements reflect all adjustments consisting of normal recurring adjustments which, in the opinion of management, are necessary for a fair statement of the Company’s financial position and results of its operations, as of and for the periods presented. The Company manages its business as one operating segment; however, the Company operates in three geographic regions: United States, Australia, and Ireland. Substantially all of the Company’s assets are located in the United States.

The Company has a relationship with a variable interest entity (“VIE”).  The Company evaluates VIEs to determine whether the Company is the primary beneficiary by performing a qualitative and quantitative analysis of each VIE that includes a review of, among other factors, the VIE’s capital structure, contractual terms, related party relationships, the Company’s fee arrangements and the design of the VIE.  This analysis includes determining whether the Company (1) has the power to direct matters that most significantly impact the activities of the VIE, and (2) has the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE.

In circumstances where the Company is not the primary beneficiary, but the Company has the ability to exercise significant influence over the operating and financial policies of a company in which it has an investment, the Company utilizes the equity method of accounting for recording investment activity. In assessing whether the Company exercises significant influence, it considers the nature and magnitude of the investment, the voting and protective rights held, any participation in the governance of the other company, and other relevant factors such as the presence of a collaboration or other business relationship. Under the equity method of accounting, the Company records in its results of operations its share of income or loss of the other company. If the Company’s share of losses exceeds the carrying value of its investment, it will suspend recognizing additional losses and will continue to do so unless the Company commits to providing additional funding. The Company monitors its investment to evaluate whether any decline in value has occurred that would be other-than-temporary, based on the implied value of recent company financings, public market prices of comparable companies, and general market conditions. The carrying value of the investment is included in the Company’s condensed consolidated balance sheet as investment in unconsolidated entity.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The results of the Company’s operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the full year or for any other period.

Concentrations of Credit Risk

The Company is exposed to credit risk from its deposits of cash, cash equivalents, short-term and long-term investments and restricted cash in excess of amounts insured by the Federal Deposit Insurance Corporation and Securities Investor Protection Corporation.

Restricted Cash

The Company had restricted cash of $10.0 million as of March 31, 2018, of which $2.5 million is classified as a current asset, as it will be used to satisfy commitments within the next 12 months. The funds are placed in an escrow account pursuant to a contractual agreement with a third-party manufacturer and will be used for payments under that agreement in 2019.

 

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the condensed consolidated balance sheets to the total of cash, cash equivalents and restricted cash shown in the condensed consolidated statement of cash flows.

Convertible Senior Notes, net

 In accordance with accounting guidance for debt with conversion and other options, the Company separately accounted for the liability and equity components of the Convertible Notes by allocating the proceeds between the liability component and the embedded conversion option (the “Equity Component”) due to the Company’s ability to settle the Convertible Notes in cash, common stock or a combination of cash and common stock, at its option. The carrying amount of the liability components was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The allocation was performed in a manner that reflected the Company’s non-convertible debt borrowing rate for similar debt. The Equity Component of the Convertible Notes was recognized as a debt discount and represents the difference between the proceeds from the issuance of the Convertible Notes and the fair value of the liability of the Convertible Notes on their respective dates of issuance. The excess of the principal amount of the liability component over its carrying amount (the “Debt Discount”) is amortized to interest expense using the effective interest method over seven years. The Equity Component is not remeasured as long as it continues to meet the conditions for equity classification. In connection with the issuance of the Convertible Notes, the Company also incurred certain offering costs directly attributable to the offering. Such costs are deferred and amortized over the term of the debt to interest expense using the effective interest method. A portion of the deferred financing costs incurred in connection with the Convertible Notes was deemed to relate to the Equity Component and was allocated to additional paid-in capital.

 Convertible preferred stock

 The Company recorded the convertible preferred stock at fair value on the date of issuance, net of issuance costs. The convertible preferred stock is recorded outside of stockholders’ equity because, in the event of certain deemed liquidation events considered not solely within the Company’s control, such as a merger, acquisition and sale of all or substantially all of the Company’s assets, the convertible preferred stock will become redeemable at the option of the holders.

Revenue recognition

In May 2016, the Company licensed the exclusive worldwide rights to its product candidate clazakizumab to Vitaeris, Inc. (“Vitaeris”), a newly formed company based in Vancouver, British Columbia. In exchange for the rights to clazakizumab, the

9


 

Company received an equity interest in Vitaeris and is eligible to receive royalties and certain other payments including revenue from the sale of drug supply inventory. The Company did not record any revenue under this agreement in the three months ended March 31, 2018 or 2017.  

In the future, the Company may generate revenue from product sales and may enter into agreements with strategic partners for the development and commercialization of the Company’s products under which revenues may consist of license fees, non-refundable upfront fees, milestones, funding of research and development activities, sales of drug supply, or other revenue. The Company could receive both fixed and variable consideration. 

On January 1, 2018, the Company adopted ASC Topic 606 and related pronouncements regarding revenue recognition using the modified retrospective method. The adoption of this guidance did not have a material impact on the Company’s condensed consolidated financial statements. In determining the appropriate amount of revenue to be recognized as it fulfills its obligations under its agreements, the Company will perform the following steps: (i) assess whether collectability is probable; (ii) identification of the promised goods or services in the contract; (iii) determination of whether the promised goods or services are performance obligations including whether they are distinct in the context of the contract; (iv) measurement of the transaction price, including the constraint on variable consideration; (v) allocation of the transaction price to the performance obligations based on estimated selling prices; and (vi) recognition of revenue when (or as) the Company satisfies each performance obligation.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in ASC Topic 606. The Company’s performance obligations may include license rights and development services. Significant management judgment will be required to determine the level of effort required under an arrangement and the period over which the Company expects to complete its performance obligations under the arrangement.

When the Company has substantive performance obligations under an arrangement accounted for as one unit of accounting, revenues will be recognized using a proportional performance-based approach. Under this approach, revenue recognition is based on costs incurred to date compared to total expected costs to be incurred over the performance period as this is considered to be representative of the delivery of service under the arrangement. Changes in estimates of total expected performance costs or service obligation time-period will be accounted for prospectively as a change in estimate. Revenues recognized at any point in time will be limited to the amount of noncontingent payments received or due.

The Company will allocate the total transaction price to each performance obligation based on the estimated relative standalone selling prices of the promised goods or service underlying each performance obligation. Estimated selling prices for license rights will be calculated using vendor-specific objective evidence, (“VSOE”), of selling price, if available, third-party evidence, (“TPE”), of selling price if VSOE is not available, or best estimate of selling price, (“BESP”), if neither VSOE nor TPE is available, and include the following key assumptions: the development timeline, revenue forecast, commercialization expenses, discount rate and probabilities of technical and regulatory success.

Licenses of intellectual property: If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company will recognize revenues from non-refundable, up-front fees allocated to the license when the license is transferred to the customer, and the customer can use and benefit from the license. For licenses that are bundled with other promises, the Company will utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company will evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

Milestone payments: At the inception of each arrangement that includes milestone payments, the Company will evaluate whether the milestones are considered probable of being achieved and estimate the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the value of the associated milestone (such as a regulatory submission by the Company) will be included in the transaction price. Milestone payments that are not within the control of the Company, such as approvals from regulators, will not be considered probable of being achieved until those approvals are received. When the Company’s assessment of probability of achievement changes and variable consideration becomes probable, any additional estimated consideration will be allocated to each performance obligation based on the estimated relative standalone selling prices of the promised goods or service underlying each performance obligation and recorded in license, collaboration, and other revenues based upon when the customer obtains control of each element.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (a) when the related sales occur, or (b) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

Collaboration payments: The Company may also perform research and development activities on behalf of collaborative partners that are paid for by the collaborators. For research and development activities which are not determined to be separate units of accounting based on the criteria above, revenues for these research and development activities will be recognized using the single unit

10


 

of accounting method for that collaborative arrangement. For research and development activities which are determined to be separate units of accounting, arrangement consideration will be allocated and revenues will be recognized as services are delivered, assuming the general criteria for revenue recognition noted above have been met. The corresponding research and development costs incurred under these contracts will be included in research and development expense in the consolidated statements of operations. For sales of drug supply inventory at cost, the revenue will be recognized upon transfer of the inventory.

The Company expects to invoice its customers upon the completion of the effort, based on the terms of each agreement. Amounts earned, but not yet collected from the customers, if any, will be included in accounts receivable in the accompanying consolidated balance sheets. Deferred revenue will arise from payments received in advance of the culmination of the earnings process. Deferred revenue expected to be recognized within the next 12 months will be classified as a current liability. Deferred revenue will be recognized as revenue in future periods when the applicable revenue recognition criteria have been met.

Long-Term Incentive Plan

In January 2018, the Company established a long-term incentive plan (“LTIP”) which provides eligible employees with the opportunity to receive performance-based compensation comprised of restricted stock units.  The vesting of the restricted stock units is contingent upon the achievement of pre-determined regulatory milestones.  The Company records compensation expense over the estimated service period for a milestone when the achievement of the milestone is considered probable, which is assessed at each reporting date.  Once a milestone is considered probable, the Company records compensation expense based on the portion of the service period elapsed to date with respect to that milestone, with a cumulative catch-up, net of estimated forfeitures, and recognizes any remaining compensation expense, if any, over the remaining estimated service period.  No compensation expense has been recorded to date under the LTIP as the conditions for recognizing expense have not yet been met.  As of March 31, 2018, the estimated value to be delivered in restricted stock units to participants eligible for the LTIP was approximately $9.6 million. The total potential value to be delivered under the LTIP is expected to change in the future for several reasons, including the addition of more eligible employees to the LTIP.

Liquidity and Going Concern

The Company has an accumulated deficit as of March 31, 2018. To date, the Company has funded its operations primarily through sales of its capital stock and Convertible Notes and payments from its former collaboration partners, and will require substantial additional capital for research and product development. In January 2018, the Company completed a private placement of 725,268 shares of convertible preferred stock resulting in net proceeds of $97.7 million. In February 2018, the Company received $277.7 million in net proceeds from the underwritten public offering of the Convertible Notes.  

The Company forecasts a significant increase in expenditures to support its planned Biologics License Application (“BLA”) submission with the U.S. Food and Drug Administration, currently anticipated to occur in the first quarter of 2019, commercial readiness activities and anticipated commercial launch of eptinezumab. The Company estimates the available cash, cash equivalents, short-term and long-term investments and restricted cash as of March 31, 2018 will be sufficient to meet the Company’s projected operating requirements into 2020. These operating requirements consist principally of expenditures related to the planned BLA submission, establishment of the eptinezumab commercial drug supply chain, continued build-out of the Company’s commercial organization (e.g., marketing, sales, medical affairs, payor access, information technology) and pre-launch market readiness. The Company has based its estimate on the timing for its projected expenditures on assumptions that may prove to be wrong, and it could utilize its available capital resources sooner than it currently expects. Furthermore, the Company’s operating plans may change, and it may need additional funds to meet operational needs and capital requirements sooner than planned. The Company will need additional funding to execute the commercial launch of eptinezumab. The Company will also need to obtain substantial additional sources of funding to develop and commercialize ALD1910 and its other product candidates. The Company expects to finance future cash needs through equity financings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing and distribution arrangements, but there are no assurances that the Company will be able to raise sufficient amounts of funding in the future on acceptable terms, or at all.  

The condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates continuity of operations, the realization of assets and the satisfaction of liabilities and commitments in the normal course of business.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, Leases. This ASU requires the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. This ASU will become effective for annual periods beginning after December 15, 2018. The Company expects adopting this guidance will result in an increase in the assets and liabilities on its consolidated balance sheets and will have some impact on its consolidated statements of operations and statement of cash flows.

11


 

The Company has reviewed other recent accounting pronouncements and concluded that they are either not applicable to the business, or that no material effect is expected on the condensed consolidated financial statements as a result of future adoption.

Net Loss Per Share Applicable to Common Stockholders

Basic net loss per share applicable to common stockholders is calculated by dividing net loss applicable to common stockholders by the weighted average common shares outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by adjusting the weighted average common shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the treasury-stock method.

Fair Value Disclosures

The Company holds financial instruments that are measured at fair value which is determined according to a fair value hierarchy that prioritizes the inputs and assumptions used, and the valuation techniques used to measure fair value. The three levels of the fair value hierarchy are described as follows:

 

Level   1

Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

 

Level   2

Inputs are quoted prices for similar assets and liabilities in active markets or quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

 

Level   3

Inputs are unobservable inputs based on the Company’s own assumptions and valuation techniques used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation.

The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

The Company established the fair value of its assets and liabilities using the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and established a fair value hierarchy based on the inputs used to measure fair value.

The Company’s negotiable certificates of deposit and U.S. government agency obligations are valued using fair value measurements that are considered to be Level 2.  The investment custodian provides the Company with valuations of its securities portfolio.  The primary source for the security valuation is Interactive Data Corporation (“IDC”), which evaluates securities based on market data.  IDC utilizes evaluated pricing models that vary by asset class and include available trade, bid, and other market information.  Generally, the methodology includes broker quotes, proprietary models, vast descriptive terms and conditions databases, as well as extensive quality control programs. The custodian utilizes proprietary valuation matrices for valuing all negotiable certificates of deposit.

 

Accounts payable and accrued liabilities are carried at cost, which approximates fair value due to the short-term nature of these financial instruments.

 

The fair value of the Convertible Notes is determined based upon data from readily available pricing sources which utilize market observable inputs and other characteristics for similar types of instruments and is included in Level 2 of the fair value hierarchy. See Note 8 for information about the determination of the carrying value of the Company’s Convertible Notes at March 31, 2018.

Investment in Unconsolidated Entity

In May 2016, the Company licensed the exclusive worldwide rights to its product candidate clazakizumab to Vitaeris. In exchange for the rights to clazakizumab, the Company received an equity stake in Vitaeris and is eligible to receive royalties and certain other payments. Since clazakizumab was developed internally by the Company, all previous expenditures to develop the compound were recognized as expense in the period incurred and there was no carrying value on the Company’s condensed consolidated balance sheet. In 2016, the Company recognized a gain on the license agreement of $1.1 million, which was determined as the initial fair value of the Company’s equity stake in Vitaeris.  

15


 

Vitaeris is a VIE for which the Company is not the primary beneficiary as the Company does not have the power to direct the activities that most significantly influence the economic performance of the entity.  In addition to the Company’s exchange of license rights for clazakizumab, Vitaeris was capitalized through cash investments by other parties. The investment in Vitaeris is accounted for under the equity method of accounting because the Company holds common stock of Vitaeris and has significant influence over the operating and financial policies of Vitaeris through its ownership, license arrangement and representation on the board of directors. Therefore, the Company records its share of any loss or income generated by Vitaeris, which is recorded on a three-month lag, within the condensed consolidated statement of operations. The investment is reflected as an investment in unconsolidated entity on the Company’s condensed consolidated balance sheet which represents the investment in Vitaeris, net of the Company’s portion of any generated loss or income.

In November 2017, the Company and Vitaeris amended the license agreement for clazakizumab and Vitaeris and its shareholders, including the Company, entered into a strategic collaboration and purchase option agreement (the “option agreement”) with a third party, CSL Limited, (“CSL”), an Australian entity, to expedite the development of clazakizumab as a therapeutic option for solid organ transplant rejection.  Pursuant to the option agreement, CSL will provide research funding to Vitaeris for the development of clazakizumab and CSL received an exclusive option to acquire Vitaeris, subject to certain terms and conditions. Upon the execution of the option agreement, Vitaeris received an upfront payment of $15 million and Vitaeris will also receive future development milestone payments.  If CSL exercises its purchase option, it will be required to make to Vitaeris’ shareholders, including the Company, an immediate one-time payment and thereafter certain sales-based milestone payments. The Company will continue to be eligible to receive royalties and certain other payments following an acquisition of Vitaeris by CSL. The Company recorded $0.2 million in net loss with respect to Vitaeris for the three months ended March 31, 2018, which was the remaining balance of the Company’s carrying value of the Company’s investment in Vitaeris. The purchase option created a written call on the Company’s shares in Vitaeris and the value of this written call is not significant. The Company has no implied or unfunded commitments related to Vitaeris and its maximum exposure to loss is limited to the current carrying value of the investment.

2025 Convertible Senior Notes, net

 

On February 1, 2018, the Company issued $250 million aggregate principal amount of the Convertible Notes in a registered underwritten public offering. In addition, on February 13, 2018, the Company issued an additional $37.5 million principal amount of Convertible Notes pursuant to the exercise of an over-allotment option granted to the underwriters in the offering.          

The Convertible Notes are senior unsecured obligations of the Company and bear interest at a rate of 2.5% per annum, payable semi-annually in arrears on February 1 and August 1 of each year, commencing on August 1, 2018. Upon conversion, the Convertible Notes will be convertible into cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election. The Convertible Notes will be subject to redemption at the Company’s option, on or after February 1, 2022, in whole or in part, if the conditions described below are satisfied. The Convertible Notes will mature on February 1, 2025, unless earlier converted, redeemed or repurchased in accordance with their terms. Subject to satisfaction of certain conditions and during the periods described below, the Convertible Notes may be converted at an initial conversion rate of 49.3827 shares of common stock per $1,000 principal amount of the Convertible Notes (equivalent to an initial conversion price of approximately $20.25 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, if certain corporate events occur prior to the maturity date, the Company will increase the conversion rate for a holder of Convertible Notes who elects to convert its Convertible Notes in connection with such a corporate event in certain circumstances.

16


 

Holders of the Convertible Notes may convert all or any portion of their notes, in multiples of $1,000 principal amount, at their option at any time prior to the close of business on the business day immediately preceding November 1, 2024 only under the following circumstances:

 

1.

during any calendar quarter commencing after the calendar quarter ending on March 31, 2018 (and only during such calendar quarter), if the last reported sale price of the Company's common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

 

2.

during the five business day period after any five consecutive trading day period (the “measurement period”) in which the "trading price" per $1,000 principal amount of the Convertible Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day;

 

3.

if the Company calls any or all of the Convertible Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or

 

4.

upon the occurrence of specified corporate events.

On or after November 1, 2024 and prior to the close of business on the business day immediately preceding February 1, 2025, holders may convert their Convertible Notes at any time.

Prior to February 1, 2022, the Company may not redeem the Convertible Notes. On or after February 1, 2022, the Company may redeem any or all of the Convertible Notes at a redemption price equal to 100% of the principal amount of the Convertible Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, if the last reported sale price of the Common Stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the trading day immediately prior to the date of the redemption notice exceeds 130% of the applicable conversion price for the Convertible Notes on each applicable trading day. If a “make-whole fundamental change” (as defined in the indenture) occurs prior to February 1, 2025, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Convertible Notes in connection with the make-whole fundamental change.

The Convertible Notes do not contain any financial or operating covenants or any restrictions on the payment of dividends, the issuance of other indebtedness or the issuance or repurchase of securities by the Company. The Convertible Notes indenture contains customary events of default, including that upon certain events of default, 100% of the principal and accrued and unpaid interest on the Convertible Notes will automatically become due and payable.

In accordance with accounting guidance for debt with conversion and other options, the Company separately accounted for the embedded conversion feature of the Convertible Notes by allocating the proceeds between the liability component and the equity component, due to the Company's ability to settle the Convertible Notes in cash, common stock or a combination of cash and common stock, at its option. The initial amount of the liability component of $177.6 million was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature and the residual between the proceeds from the issuance of $287.5 million and the fair value of the liability of $177.6 million is allocated to the equity component, which was recorded at$109.9 million and recognized as a debt discount. In addition, the Company incurred approximately $9.8 million of debt issuance costs, which primarily consisted of underwriting, legal and other professional fees. The issuance costs were allocated to the liability and equity components proportionally based on the allocation of total proceeds.  A total of $3.7 million was allocated to the equity component and recorded as a reduction to additional paid-in capital and $6.1 million was allocated to the liability component and is recorded as a reduction of the Convertible Notes in the Company’s condensed consolidated balance sheet.

The debt discount and the issuance costs will be amortized to interest expense using the effective interest method over seven years, the expected life of the Convertible Notes as discussed below. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. During the three months ended March 31, 2018, the Company recorded $1.7 million of interest expense related to the amortization of the debt discount and issuance costs and the unamortized balance of the liability was $173.2 million as of March 31, 2018.  

While the Convertible Notes are classified on the Company’s condensed consolidated balance sheet at March 31, 2018 as long-term, the resulting balance sheet classification of this liability will be monitored at each quarterly reporting date and will be analyzed dependent upon whether the Convertible Notes are convertible or subject to an event triggering potential redemption during the prescribed measurement periods. In the event that the holders of the Convertible Notes have the election to convert the Convertible Notes or the Convertible Notes become redeemable at any time during the prescribed measurement period, the Convertible Notes would then be considered a current obligation and classified as such.

While for US GAAP purposes, the convertible note is allocated between the liability component and the equity component, for US tax purposes there is no allocation, and a deferred tax liability is recognized related to such difference. Because the Company has a full valuation allowance recorded against net deferred tax assets, there is no net impact on the Company’s condensed consolidated balance sheets or condensed consolidated statements of operations as a result of establishing this deferred tax liability.

The Company determined the expected life of the Convertible Notes was equal to its seven-year term. The effective interest rate on the liability component of the Convertible Notes for the period from the date of issuance through March 31, 2018 was 10.6%. As of March 31, 2018, the "if-converted value" did not exceed the remaining principal amount of the Convertible Notes. The fair value of the Convertible Notes is based on data from readily available pricing sources which utilize market observable inputs and other characteristics for similar types of instruments, and, therefore, these Convertible Notes are classified within Level 2 in the fair value hierarchy. The fair value of the Convertible Notes, which differs from their carrying value, is influenced by interest rates, the Company’s stock price and stock price volatility. The estimated fair value of the Convertible Notes as of March 31, 2018 was approximately $265.5 million.
