The Company may not redeem the Notes prior to May 6, 2021. The Company may redeem for cash all or part of the Notes, at its option, on or after May 6, 2021 if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.
If the Company experiences a fundamental change, as described in the Indenture, prior to the maturity date of the Notes, holders of the Notes will, subject to specified conditions, have the right, at their option, to require the Company to repurchase for cash all or a portion of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. In addition, following certain corporate events that occur prior to the maturity date of the Notes and following a notice of redemption of the notes, the Company will increase the conversion rate for a holder who elects to convert its Notes in connection with such corporate event or redemption.
The Indenture provides for customary events of default. In the case of an event of default with respect to the Notes arising from specified events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. If any other event of default with respect to the Notes under the Indenture occurs or is continuing, the Trustee or holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare the principal amount of the Notes to be immediately due and payable.
In certain circumstances if, at any time during the six-month period beginning on, and including, the date that is six months after the last date of original issuance of the Notes, the Company fails to timely file certain documents or reports required under the Securities Exchange Act of 1934, as amended, or the Notes are not otherwise freely tradable by holders of the Notes other than the Company’s affiliates or holders that were the Company’s affiliates at any time during the three months immediately preceding, additional interest will accrue on the Notes during the first 90-day period in which its failure to file has occurred and is continuing or such Notes are not otherwise freely tradable by holders other than the Company’s affiliates (or holders that were the Company’s affiliates at any time during the three months immediately preceding).
In addition, if, and for so long as, the restrictive legend on the Notes has not been removed, the Notes are assigned a restricted CUSIP number or the Notes are not otherwise freely tradable by holders other than the Company’s affiliates or holders that were our affiliates at any time during the three months immediately preceding (without restrictions pursuant to U.S. securities laws or the terms of the Indenture or the Notes) as of the 380th day after the last date of original issuance of the Notes, the Company will pay additional interest on the Notes outstanding during the period in which the Notes remain so restricted.
The Company received net proceeds of $158.8 million after deducting commissions, fees and other offering expenses of $6.2 million.
14. Income Taxes
The Company recorded no provision for income taxes for the three months ended March 31, 2018 and 2017.
Deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and tax bases of assets and liabilities using statutory rates. Management of the Company has evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets, which are comprised principally of net operating loss carryforwards and research and development credits. Under the applicable accounting standards, management has considered the Company’s history of losses and concluded that it is more likely than not that the Company will not recognize the benefits of federal and state deferred tax assets. Accordingly, a full valuation allowance has been established against the Company’s otherwise recognizable net deferred tax assets.
On December 22, 2017, the new tax reform law, which is commonly referred to as the Tax Cuts and Jobs Act, or the Act, was signed into law by President Trump. The Act includes a number of provisions, including the lowering of the U.S. corporate tax rate from 35 percent to 21 percent, effective January 1, 2018 and the establishment of a territorial-style system for taxing foreign-source income of domestic multinational corporations. The Company is in the process of quantifying the tax impacts of the Act. Due to the Company's full valuation allowance, no provisional tax expense or benefit associated with the re-measurement was recognized in the Company's consolidated statement of operations and comprehensive loss for the period ended March 31, 2018.
The Company has recognized the provisional tax impacts related to the revaluation of the deferred tax assets and liabilities and
