[S-3ASR] NuScale Power Corporation SEC Filing

Rhea-AI Filing Summary

NuScale Power Corporation has filed an automatic shelf registration that permits it to offer Class A common stock, preferred stock, depositary shares, debt securities, warrants and units from time to time. The prospectus describes broad offering flexibility and states proceeds will be used for general corporate purposes, including working capital, operating expenses and capital expenditures, with unused proceeds invested in short-term, investment-grade instruments.

The company reports authorized capitalization of 512,000,000 shares (332,000,000 Class A; 179,000,000 Class B; 1,000,000 preferred) and discloses 133,753,450 Class A shares and 150,983,449 Class B shares outstanding. NuScale highlights its core product, the NuScale Power Module™, as a 77 million watt unit. The prospectus also details governance features: the Board may create preferred stock without stockholder approval, anti-takeover provisions and an exclusive forum clause, and certain historical parties hold registration rights.

Positive

• Automatic shelf registration as a well-known seasoned issuer provides flexible access to capital across equity, debt and hybrid instruments
• NYSE listing and ticker: Class A common stock trades under SMR, providing liquidity and market access
• Proprietary technology highlighted: the NuScale Power Module™ is described as a 77 million watt generating unit

Negative

• Board authority to issue preferred stock without stockholder approval could dilute common shareholders and affect control or market price
• Anti-takeover provisions and exclusive forum clause limit stockholder actions, potentially discouraging change-of-control transactions

Insights

Financial Analyst

TL;DR Shelf registration gives NuScale flexible capital-raising ability; share counts and authorized capitalization define dilution scope.

The S-3 shelf establishes an efficient mechanism for NuScale to access equity, debt and hybrid financing as market conditions permit, which is useful for a capital-intensive developer of small modular reactors. The document confirms 133,753,450 Class A and 150,983,449 Class B shares outstanding and an authorized pool totaling 512,000,000 shares, which quantifies dilution capacity. Use of proceeds is described as general corporate purposes, indicating no earmarked project financing in the base prospectus. Impact classification: not impactful to immediate operations but material for financing strategy.

Corporate Governance Expert

TL;DR Charter grants board-wide authority to issue preferred stock and includes anti-takeover provisions that constrain shareholder influence.

The prospectus discloses that the Board can establish and issue preferred stock, set its rights and terms and do so without stockholder approval within the authorized 1,000,000 preferred shares. That authority, combined with anti-takeover provisions (limits on special meetings, no cumulative voting) and an exclusive forum clause, may delay or deter control transactions and affects governance risk for holders of Class A common stock. The Registration Rights Agreement also preserves resale pathways for certain historical owners, affecting supply dynamics. Impact classification: impactful and negative for shareholder control considerations.

ABOUT THIS PROSPECTUS

This prospectus is part of an automatic shelf registration statement that we filed with the U.S. Securities and Exchange Commission (the “SEC”), as a “well-known seasoned issuer” ​(as defined in Rule 405 of the Securities Act of 1933, as amended (the “Securities Act”)). Under this shelf registration process, we may, from time to time, offer and sell the securities described in this prospectus in one or more offerings.

We have provided to you in this prospectus a general description of the securities we may offer. Each time we sell securities under this shelf registration process, we will provide a prospectus supplement that will contain specific information about the terms of that offering. That prospectus supplement may include additional risk factors or other special considerations applicable to the securities being offered. We may also add, update or change in the prospectus supplement any of the information contained in this prospectus. To the extent there is a conflict between the information contained in this prospectus and the prospectus supplement, you should rely on the information in the prospectus supplement, provided that if a statement in any document is inconsistent with a statement in another document having a later date — for example, a document incorporated by reference in this prospectus or any prospectus supplement — the statement in the document having the later date modifies or supersedes the earlier statement. You should read both this prospectus and the prospectus supplement together with the additional information described under “Where You Can Find More Information; Incorporation of Documents by Reference” in their entirety before investing in any of our securities.

The registration statement containing this prospectus, including the exhibits to the registration statement, provides additional information about us and the securities offered under this prospectus. The registration statement, including the exhibits, can be read at the SEC’s website mentioned under the heading “Where You Can Find More Information; Incorporation of Documents by Reference.”

You should rely only on the information contained in, or incorporated by reference into, this prospectus, in any accompanying prospectus supplement or in any free writing prospectus filed by us with the SEC. We have not authorized anyone to provide you with any different or additional information or to make any representations other than those contained in this prospectus, any applicable prospectus supplement or in any document incorporated by reference thereto. We are not offering to sell or soliciting any offer to buy any securities in any jurisdiction where the offer or sale is not permitted. You should not assume that the information in this prospectus, any applicable prospectus supplement or in any document incorporated by reference is accurate as of any date other than the date on the front cover of the applicable document. We take no responsibility for, and provide no assurances as to the reliability of, any other information that others may give you. No dealer, salesperson or other person is authorized to give any information or to represent anything not contained in this prospectus, any applicable prospectus supplement or any related free writing prospectus. This prospectus and any applicable prospectus supplement is not an offer to sell securities, and it is not soliciting an offer to buy securities, in any jurisdiction where the offer or sale is not permitted.

Unless the context requires otherwise, references to the “Company,” “NuScale,” “we,” “our,” and “us,” refer to NuScale Power Corporation and its subsidiaries, except that such terms refer to only NuScale Power Corporation and not its subsidiaries in the section entitled “Description of Securities.” Where appropriate, we differentiate between NuScale Power Corporation and its operating subsidiary, NuScale Power, LLC, by referring to them as “NuScale Corp” and “NuScale LLC,” respectively.

TABLE OF CONTENTS​

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this prospectus may constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act of 1934, as amended (the “Exchange Act”), that are not historical facts and involve risks and uncertainties that could cause actual results to differ materially from those expected and projected. All statements, other than statements of historical fact included in this prospectus, including, without limitation, statements regarding our financial position and business strategy and the expectations, beliefs, intentions, plans and objectives of management for future operations are forward-looking statements. Words such as “anticipate,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “seek,” “should,” “will,” “would” and variations and similar words and expressions are intended to identify such forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements in this prospectus may include, for example, statements about:

•

our need for and ability to obtain additional equity or other sources of funding;

​

•

our financial and business performance, including financial projections and business metrics;

​

•

our expectations regarding obtaining regulatory approvals, and the timing thereof, to deploy our small modular reactors (“SMRs”) in the United States and abroad;

​

•

forecasts regarding end-customer adoption rates and demand for our products in markets that are new and rapidly evolving;

​

•

macroeconomic conditions;

​

•

developments and projections relating to our partners, competitors and industry;

​

•

limitations on the effectiveness of our controls and procedures and our remediation plans related thereto;

​

•

our anticipated growth rates and market opportunities;

​

•

litigation contingencies; and

​

•

the potential for our business development efforts to maximize the potential value of our portfolio.

​

Such forward-looking statements contained in this prospectus relate to future events or future performance, but reflect management’s current beliefs, based on information currently available. Many factors could cause actual events, performance or results to differ materially from the events, performance and results discussed in the forward-looking statements, and there can be no assurance that future developments affecting us will be those we have anticipated.

Important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements are summarized above and described or referenced in more detail under the heading “Risk Factors.” If one or more of these risks or uncertainties materialize, or if any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. There may be additional risks that we currently consider immaterial or which are unknown. It is not possible to predict or identify all such risks. Except as expressly required by applicable securities laws, we disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. No person should take any statement regarding past trends or activities as a representation that the trends or activities will continue in the future.

TABLE OF CONTENTS​

DESCRIPTION OF CAPITAL STOCK

The following summary of provisions of securities we may issue under this prospectus does not purport to be complete and is subject to our Certificate of Incorporation, dated April 29, 2022 (as amended, our “Charter”), our bylaws, dated April 29, 2022 (our “Bylaws,” and, together with our Charter, our “Organizational Documents”), the Amended and Restated Registration Rights Agreement, dated May 2, 2022, between us and other specified parties (the “Registration Rights Agreement”) and the provisions of applicable law.

AUTHORIZED CAPITALIZATION

Our Charter authorizes the issuance of 512,000,000 shares of capital stock, par value $0.0001 per share, consisting of:

•

332,000,000 shares of Class A common stock, with the par value of $0.0001 per share (the “Class A Common Stock”);

​

•

179,000,000 shares of Class B common stock, par value $0.0001 per share (“Class B Common Stock”); and

​

•

1,000,000 shares of preferred stock, with the par value of $0.0001 per share (the “Preferred Stock”).

​

As of June 30, 2025, we had 133,753,450 outstanding shares of Class A Common Stock and 150,983,449 outstanding shares of Class B Common Stock. Our Class A Common Stock is listed on the New York Stock Exchange (“NYSE”) and trades under the symbol “SMR.” Each share of Class B Common Stock represents the right to cast one vote and is paired with a Class B unit of NuScale Power, LLC (“NuScale LLC,” and such units “NuScale LLC Class B Units”); each Class B Unit may be converted into a share of Class A Common Stock (and upon such exchange the paired share of Class B Common Stock is cancelled).

DESCRIPTION OF CLASS A COMMON STOCK

Voting rights.   Each holder of Class A Common Stock is entitled to one vote for each share of Class A Common Stock held of record by such holder on all matters on which stockholders generally are entitled to vote. The holders of Class A Common Stock and Class B Common Stock will vote together as a single class on all matters (or, if any holders of preferred stock are entitled to vote together with the holders of common stock, as a single class with the holders of preferred stock); provided, that the holders of the outstanding shares of Class A Common Stock will be entitled to vote separately upon any amendment to the Charter (including by merger, consolidation, reorganization or similar event) that would alter or change the powers, preferences or special rights of the Class A Common Stock in a manner that is disproportionately adverse compared to the Class B Common Stock.

Subject to the rights of the holders of any one or more series of preferred stock then outstanding, the number of authorized shares of Class A Common Stock may be increased or decreased by the affirmative vote of the holders of a majority of the total voting power of the outstanding shares of capital stock entitled to vote thereon, voting together as a single class, irrespective of the provisions of Section 242(b)(2) of the Delaware General Corporation Law (“DGCL”), and no vote of the holders of Class A Common Stock voting separately as a class will be required therefor; provided, that the number of authorized shares of any particular class may not be decreased below the number of shares of such class then outstanding, plus the number of shares of Class A Common Stock issuable in connection with (i) the exchange of all outstanding NuScale LLC Class B Units, and the cancellation of all Class B Common Stock, pursuant to the Sixth Amended and Restated Limited Liability Company Agreement of NuScale LLC, dated as of May 2, 2022 (the “NuScale LLC Agreement”) and (ii) the exercise of outstanding options, warrants, exchange rights, conversion rights or similar rights for Class A Common Stock.

Holders of Class A Common Stock do not have the ability to cumulate votes for the election of directors. The Charter does not require the election of the directors to be by written ballot.

Notwithstanding the foregoing, to the fullest extent permitted by law and subject to the Charter, holders of shares of Class A Common Stock, as such, will have no voting power with respect to, and will not be entitled to vote on, any amendment to the Charter (including any certificate of designations relating

4

TABLE OF CONTENTS​​

to any series of preferred stock) that relates solely to the terms of any outstanding preferred stock if the holders of such preferred stock are entitled to vote as a separate class thereon under our Charter (including any certificate of designations relating to any series of preferred stock) or pursuant to the DGCL.

Dividend Rights.   Subject to applicable law and the rights, if any, of the holders of any outstanding series of preferred stock or any class or series of stock having a preference senior to or the right to participate with the Class A Common Stock with respect to the payment of dividends, such dividends and other distributions of cash, stock or property may be declared and paid on the Class A Common Stock out of the assets of the Company that are by law available therefor, at the times and in the amounts as the Board in its discretion may determine.

Rights upon liquidation.   In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of NuScale Corp, after payment or provision for payment of the debts and other liabilities of NuScale Corp and of the preferential and other amounts, if any, to which the holders of preferred stock are entitled, if any, the holders of all outstanding shares of Class A Common Stock will be entitled to receive, pari passu, an amount per share equal to the par value thereof, and thereafter the holders of all outstanding shares of Class A Common Stock will be entitled to receive the remaining assets of NuScale Corp available for distribution ratably in proportion to the number of shares of Class A Common Stock.

Other rights.   Except as provided in the Registration Rights Agreement (as applicable), the holders of Class A Common Stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the Class A Common Stock. The rights, preferences and privileges of holders of Class A Common Stock are subject to those of the holders of any shares of the preferred stock that NuScale Corp may issue in the future and to the Registration Rights Agreement, as applicable.

Subject to the transfer and exchange restrictions set forth in the NuScale LLC Agreement, holders of NuScale LLC Class B Units may exchange them for shares of Class A Common Stock (or cash at our election), subject to certain restrictions.

DESCRIPTION OF PREFERRED STOCK

No shares of preferred stock are currently issued or outstanding. Our Charter authorizes the Board to establish one or more series of preferred stock in one or more classes or series and to fix the rights, preferences, privileges and related restrictions, including dividend rights, dividend rates, conversion rights, voting rights, the right to elect directors, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any class or series, or the designation of the class or series, without the approval of our stockholders; provided, that the aggregate number of shares issued and not retired of any and all such series shall not exceed the total number of shares of preferred stock authorized by our Charter (1,000,000 shares).

The authority of the Board to issue preferred stock without approval of our stockholders may have the effect of delaying, deferring or preventing a change in control of our company and may adversely affect the voting and other rights of the holders of our common stock. The issuance of preferred stock with voting and conversion rights may adversely affect the voting power of the holders of our common stock, including the loss of voting control to others. As a result of these or other factors, the issuance of preferred stock could have an adverse impact on the market price of our Class A Common Stock.

PROVISIONS OF DELAWARE LAW AND OTHER PROVISIONS THAT AFFECT STOCKHOLDER RIGHTS

Anti-Takeover Effects of Provisions of Delaware Law and our Organizational Documents

Certain provisions of our Organizational Documents could discourage potential acquisition proposals and could delay or prevent a change in control. These provisions are intended to enhance the likelihood of continuity and stability in the composition of the Board and in the policies formulated by the Board and to discourage certain types of transactions that may involve an actual or threatened change of control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal or proxy fight. Such

5

TABLE OF CONTENTS

provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of Class A Common Stock that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management or delaying or preventing a transaction that might benefit you or other minority stockholders.

These provisions include:

Action by Written Consent; Special Meetings of Stockholders.   The DGCL permits stockholder action by written consent unless otherwise provided by our Charter. Our Organizational Documents provide that special meetings of stockholders may be called only (i) by the chairperson of the Board, (ii) by our chief executive officer, or (iii) at the direction of the Board pursuant to a written resolution adopted by a majority of the total number of directors that we would have if there were no vacancies; provided, that only proposals included in our notice may be considered at such special meetings. As of October 4, 2024, we ceased to be a “Controlled Company” pursuant to Section 303A.00 of the NYSE Listed Company Manual.

Election and Removal of Directors.   The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless our Charter provides otherwise. Our Charter disallows cumulative voting. Any directors or the entire Board may be removed at any time, but only for cause, upon the affirmative vote of the holders of at least a majority of the total voting power of the outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class. In addition, the certificate of designation pursuant to which a particular series of preferred stock is issued may provide holders of that series of preferred stock with the right to elect additional directors. These provisions could delay a successful tender offeror from obtaining majority control of the Board, and the prospect of that delay might deter a potential offeror.

Authorized but Unissued Shares.   Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of the NYSE, which would apply if and so long as the Class A Common Stock remains listed on the NYSE, require stockholder approval of certain issuances equal to or exceeding 20% of the then-outstanding voting power or then-outstanding number of shares of Class A Common Stock. Additional shares that may be issued in the future may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions. The existence of authorized but unissued and unreserved common stock and preferred stock could make it more difficult to, or discourage an attempt to, obtain control of us by means of a proxy contest, tender offer, merger or otherwise and thereby protect the continuity of our management and possibly deprive stockholders of opportunities to sell their shares of Class A Common Stock at prices higher than prevailing market prices.

Business Combinations with Interested Stockholders.   Section 203 of the DGCL provides that if a person acquires 15% or more of the voting stock of a Delaware corporation, such person becomes an “interested stockholder” and may not engage in certain “business combinations” with the corporation for a period of three years from the time such person acquired 15% or more of the corporation’s voting stock, unless: (1) the board of directors approves the acquisition of stock or the merger transaction before the time that the person becomes an interested stockholder; (2) the interested stockholder owns at least 85% of the outstanding voting stock of the corporation at the time the merger transaction commences (excluding voting stock owned by directors who are also officers and certain employee stock plans); or (3) the merger transaction is approved by the board of directors and by the affirmative vote at a meeting, not by written consent, of stockholders of two-thirds of the holders of the outstanding voting stock which is not owned by the interested stockholder. A Delaware corporation may elect in its certificate of incorporation or bylaws not to be governed by this particular Delaware law.

Other Limitations on Stockholder Actions.   Our Bylaws also impose procedural requirements on stockholders who wish to:

•

make nominations in the election of directors;

​

•

propose that a director be removed; or

​

•

propose any other business to be brought before an annual or special meeting of stockholders.

​

6

TABLE OF CONTENTS

Under these procedural requirements, in order to bring a proposal before a meeting of stockholders, a stockholder must deliver timely notice of a proposal pertaining to a proper subject for presentation at the meeting to our corporate secretary containing, among other things, the following:

•

the stockholder’s name and address;

​

•

the number of shares beneficially owned by the stockholder and evidence of such ownership;

​

•

the names of all persons with whom the stockholder is acting in concert and a description of all arrangements and understandings with those persons;

​

•

a description of any agreement, arrangement or understanding reached with respect to shares of our common stock or preferred stock, such as borrowed or loaned shares, short positions, hedging or similar transactions;

​

•

a description of the business or nomination to be brought before the meeting and the reasons for conducting such business at the meeting; and

​

•

any material interest of the stockholder in such business.

​

Our Bylaws set out the timeliness requirements for delivery of notice.

Limitations on Liability and Indemnification of Officers and Directors

Our Organizational Documents provide indemnification for our directors and officers to the fullest extent permitted by the DGCL. We have entered into indemnification agreements with each of our directors and executive officers that may, in some cases, be broader than the specific indemnification provisions contained under Delaware law. In addition, as permitted by Delaware law, our Charter includes provisions that eliminate the personal liability of our directors and officers for monetary damages resulting from breaches of certain fiduciary duties as a director or officer, as applicable. The effect of this provision is to restrict our rights and the rights of our stockholders in derivative suits to recover monetary damages against a director or officer for breach of fiduciary duties as a director or officer. These provisions may be held to be not enforceable for violations of the federal securities laws of the United States.

Exclusive Forum

The Charter provides that, unless NuScale Corp consents in writing to the selection of an alternative forum, (i) the sole and exclusive forum for any complaint asserting any internal corporate claims (as defined below), to the fullest extent permitted by law, and subject to applicable jurisdictional requirements, shall be the Court of Chancery of the State of Delaware (the “Court of Chancery”) (or, if the Court of Chancery does not have, or declines to accept, jurisdiction, another state court or a federal court located within the State of Delaware); and (ii) the sole and exclusive forum for any complaint asserting a cause of action arising under the Securities Act, to the fullest extent permitted by law, shall be the federal district courts of the United States; provided, that the Charter’s forum selection provision does not apply to suits brought to enforce a duty or liability created by the Exchange Act. For purposes of the Charter’s forum selection provision, “internal corporate claims” means claims, including claims in the right of NuScale Corp that are based upon a violation of a duty by a current or former director, officer, employee or stockholder in such capacity, or as to which the DGCL confers jurisdiction upon the Court of Chancery. Any person or entity purchasing or otherwise acquiring or holding any interest in any shares of our capital stock shall be deemed to have notice of and to have consented to the forum provisions in the Charter. However, it is possible that a court could find our forum selection provisions to be inapplicable or unenforceable. Although we believe this provision benefits us by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors, officers and other employees.

DESCRIPTION OF DEPOSITARY SHARES

General

We may, at our option, elect to offer fractional shares of preferred stock, which we call depositary shares, rather than full shares of preferred stock. If we do, we will issue to the public receipts, called depositary receipts, for depositary shares, each of which will represent a fraction, to be described in the applicable prospectus supplement, of a share of a particular series of preferred stock. Unless otherwise provided in the prospectus supplement, each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in a share of preferred stock represented by the depositary share, to all the rights and preferences of the preferred stock represented by the depositary share. Those rights include dividend, voting, redemption, conversion and liquidation rights.

The shares of preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary under a deposit agreement between us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence with and paying certain charges to the depositary.

The summary of terms of the depositary shares contained in this prospectus is not a complete description of the terms of the depositary shares. You should refer to the form of the deposit agreement, our articles of organization and the certificate of designation for the applicable series of preferred stock that are, or will be, filed with the SEC.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions, if any, received in respect of the preferred stock underlying the depositary shares to the record holders of depositary shares in proportion to the numbers of depositary shares owned by those holders on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for the underlying preferred stock.

If there is a distribution other than in cash, the depositary will distribute property (including securities) received by it to the record holders of depositary shares, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary may, with our approval, adopt another method for the distribution, including selling the property and distributing the net proceeds from the sale to the holders.

Liquidation Preference

If a series of preferred stock underlying the depositary shares has a liquidation preference, in the event of our voluntary or involuntary liquidation, dissolution or winding up, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.

Withdrawal of Stock

Unless the related depositary shares have been previously called for redemption, upon surrender of the depositary receipts at the office of the depositary, the holder of the depositary shares will be entitled to delivery, at the office of the depositary or upon his or her order, of the number of whole shares of the preferred stock and any money or other property represented by the depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. In no event will the depositary deliver fractional shares of preferred stock upon surrender of depositary receipts. Holders of preferred stock thus withdrawn may not thereafter deposit those shares under the deposit agreement or receive depositary receipts evidencing depositary shares therefor.

TABLE OF CONTENTS

Redemption of Depositary Shares

Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing shares of the preferred stock so redeemed, so long as we have paid in full to the depositary the redemption price of the preferred stock to be redeemed plus an amount equal to any accumulated and unpaid dividends on the preferred stock to the date fixed for redemption. The redemption price per depositary share will be equal to the redemption price and any other amounts per share payable on the preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata or by any other equitable method as may be determined by the depositary.

After the date fixed for redemption, depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of depositary shares will cease, except the right to receive the monies payable upon redemption and any money or other property to which the holders of the depositary shares were entitled upon redemption upon surrender to the depositary of the depositary receipts evidencing the depositary shares.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts relating to that preferred stock. The record date for the depositary receipts relating to the preferred stock will be the same date as the record date for the preferred stock. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the number of shares of preferred stock represented by that holder’s depositary shares. The depositary will endeavor, insofar as practicable, to vote the number of shares of preferred stock represented by the depositary shares in accordance with those instructions, and we will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote any shares of preferred stock except to the extent it receives specific instructions from the holders of depositary shares representing that number of shares of preferred stock.

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay the charges due to the depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and such other charges (including those in connection with the receipt and distribution of dividends, the sale or exercise of rights, the withdrawal of the preferred stock and the transferring, splitting or grouping of depositary receipts) as are expressly provided in the deposit agreement to be for their accounts. If these charges have not been paid by the holders of depositary receipts, the depositary may refuse to transfer depositary shares, withhold dividends and distributions and sell the depositary shares evidenced by the depositary receipt.

Amendment and Termination of the Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between us and the depositary. The terms of any amendment, including the requisite approvals, will be set forth in the applicable deposit agreement.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering to us notice of its election to do so, and we may remove the depositary at any time. Any resignation or removal of the depositary will take effect upon our appointment of a successor depositary and its acceptance of such appointment.

Notices

The depositary will forward to holders of depositary receipts all notices, reports and other communications, including proxy solicitation materials received from us, that are delivered to the depositary

10

TABLE OF CONTENTS

and that we are required to furnish to the holders of the preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock.

DESCRIPTION OF DEBT SECURITIES

General

The following description sets forth general terms that will apply to the debt securities. We will describe the particular terms of any debt securities that we offer in the prospectus supplement relating to those debt securities.

The debt securities will be either our senior debt securities or our subordinated debt securities. The senior debt securities will be issued under an indenture between us and the trustee named in the indenture. We refer to this indenture as the “senior indenture.” The subordinated debt securities will be issued under a separate subordinated indenture between us and the trustee named in the indenture. We refer to this indenture as the “subordinated indenture” and, together with the senior indenture, as the “indentures.” Except as permitted by applicable law, the indentures have been or will be qualified under the Trust Indenture Act of 1939 (the “Trust Indenture Act”).

We have filed the forms of the indentures as exhibits to this registration statement. Capitalized terms not otherwise defined in this prospectus will have the meanings given in the indenture to which they relate.

The following summaries of provisions of the debt securities and the indentures are not complete and are qualified in their entirety by reference to the provisions of the indentures and the debt securities.

Neither of the indentures limits the principal amount of debt securities that we may issue. Each indenture provides that debt securities may be issued in one or more series up to the principal amount that we may authorize from time to time. Each indenture also provides that the debt securities may be denominated in any currency or currency unit that we designate. In addition, each series of debt securities may be reopened in order to issue additional debt securities of that series in the future without the consent of the holders of debt securities of that series. Unless otherwise described in the prospectus supplement relating to a particular offering, neither the indentures nor the debt securities will contain any provisions to afford holders of any debt securities protection in the event of a takeover, recapitalization or similar restructuring of our business.

Unless otherwise described in the prospectus supplement relating to a particular offering, the senior debt securities will rank equally with all of our other unsecured and unsubordinated debt. The subordinated debt securities will be subordinated to the prior payment in full of our senior debt securities. We will describe the particular terms of the subordinated debt securities that we offer in the prospectus supplement relating to those subordinated debt securities.

We will describe the specific terms relating to each particular series of debt securities in the prospectus supplement relating to the offering of those debt securities. The terms we will describe in the prospectus supplement will include some or all of the following:

•

the title and type of the debt securities;

​

•

the total principal amount or initial offering price of the debt securities;

​

•

the date or dates when the principal of the debt securities will be payable;

​

•

whether we will have the right to extend the stated maturity of the debt securities;

​

•

whether the debt securities will bear interest and, if so, the rate or rates, or the method for calculating the rate or rates, of interest;

​

•

if the debt securities will bear interest, the date from which interest will accrue, the dates when interest will be payable and the regular record dates for these interest payment dates;

​

•

the place where the principal, premium, if any, and interest, if any, on the debt securities will be paid, registered debt securities may be surrendered for registration of transfer, and debt securities may be surrendered for exchange;

​

•

any sinking fund or other provisions that would obligate us to repurchase or otherwise redeem the debt securities;

​

12

TABLE OF CONTENTS

•

the terms and conditions upon which we will have the option or the obligation to redeem the debt securities;

​

•

the denominations in which any registered debt securities will be issuable;

​

•

the identity of each security registrar and paying agent, and the designation of the exchange rate agent, if any, if other than the trustee;

​

•

the portion of the principal amount of debt securities that will be payable upon acceleration of the maturity of the debt securities;

​

•

the currency used to pay principal, premium, if any, and interest, if any, on the debt securities, if other than U.S. dollars, and whether you or we may elect to have principal, premium and interest paid in a currency other than the currency in which the debt securities are denominated;

​

•

any index, formula or other method used to determine the amount of principal, premium or interest on the debt securities;

​

•

any changes or additions to the events of default, defaults or our covenants made in the applicable indenture;

​

•

whether the debt securities are issuable as registered debt securities or bearer debt securities, whether there are any restrictions relating to the form in which they are issued and whether bearer and registered debt securities may be exchanged for each other;

​

•

to whom interest will be payable:

​

•

if other than the registered holder (for registered debt securities),

​

•

if other than upon presentation and surrender of the related coupons (for bearer debt securities), or

​

•

if other than as specified in the indentures (for global debt securities);

​

•

whether the debt securities are to be convertible or exchangeable for other securities and, if so, the terms of conversion or exchange;

​

•

particular terms of subordination with respect to subordinated debt securities; and

​

•

any other terms of the debt securities consistent with the provisions of the applicable indenture.

​

We may issue debt securities as original issue discount securities to be sold at a substantial discount below their principal amount. If we issue original issue discount securities, then we will describe the material U.S. federal income tax consequences that apply to those debt securities in the applicable prospectus supplement.

Registration and Transfer

We expect to issue each series of debt securities only as registered securities. However, we may issue a series of debt securities as bearer securities, or a combination of both registered securities and bearer securities. If we issue senior debt securities as bearer securities, they will have interest coupons attached unless we elect to issue them as zero coupon securities. If we issue bearer securities, we may describe material U.S. federal income tax consequences and other material considerations, procedures and limitations in the applicable prospectus supplement.

Holders of registered debt securities may present the debt securities for exchange for different authorized amounts of other debt securities of the same series and in the same aggregate principal amount at the corporate trust office of the trustee or at the office of any other transfer agent we may designate for the purpose and describe in the applicable prospectus supplement. The registered securities must be duly endorsed or accompanied by a written instrument of transfer. The agent will not impose a service charge on you for the transfer or exchange. We may, however, require that you pay any applicable tax or other governmental charge. If we issue bearer securities, we will describe any procedures for exchanging those bearer securities for other senior debt securities of the same series in the applicable prospectus supplement. Generally, we will not allow you to exchange registered securities for bearer securities.

13

TABLE OF CONTENTS

In general, unless otherwise specified in the applicable prospectus supplement, we will issue registered securities without coupons and in denominations of $1,000 or integral multiples thereof. We may issue both registered and bearer securities in global form.

Conversion and Exchange

If any debt securities will be convertible into or exchangeable for our common stock, preferred stock or other securities, the applicable prospectus supplement will set forth the terms and conditions of the conversion or exchange, including:

•

the conversion price or exchange ratio;

​

•

the conversion or exchange period;

​

•

whether the conversion or exchange will be mandatory or at the option of the holder or us;

​

•

provisions for adjustment of the conversion price or exchange ratio; and

​

•

provisions that may affect the conversion or exchange if the debt securities are redeemed.

​

Redemption

Unless otherwise indicated in the applicable prospectus supplement, we may, at our option, redeem any series of debt securities in whole at any time or in part from time to time. If any series of debt securities are redeemable only on or after a certain date or only upon satisfaction of additional conditions, the applicable prospectus supplement will specify the date or the additional conditions. Unless otherwise specified in the applicable prospectus supplement, the redemption price for debt securities will equal 100% of the principal amount plus any accrued and unpaid interest on those debt securities.

The applicable prospectus supplement will contain the specific terms on which we may redeem a series of debt securities prior to its stated maturity. Unless otherwise described in the prospectus supplement relating to a particular offering, we will send a notice of redemption to holders at least 30 days, but not more than 60 days, prior to the redemption date. The notice will state:

•

the redemption date;

​

•

the redemption price (including accrued interest, if any);

​

•

if less than all of the debt securities of the series are being redeemed, the particular debt securities to be redeemed (and the principal amounts, in the case of a partial redemption);

​

•

that on the redemption date, the redemption price will become due and payable and any applicable interest will cease to accrue on and after that date;

​

•

the place or places where the debt securities are to be redeemed;

​

•

whether the redemption is for a sinking fund;

​

•

the CUSIP number(s) and/or common codes for the debt securities being redeemed; and

​

•

any other provisions required by the terms of the debt securities of the series that are being redeemed.

​

On or before any redemption date, we will deposit an amount of money with the trustee or with a paying agent sufficient to pay the redemption price.

Unless otherwise described in the prospectus supplement relating to a particular offering, if we are redeeming less than all the debt securities, the trustee will select the debt securities to be redeemed using a method it considers fair and appropriate. After the redemption date, holders of redeemed debt securities will have no rights with respect to the debt securities except the right to receive the redemption price and any unpaid interest to the redemption date.

Events of Default

Unless otherwise described in the prospectus supplement relating to a particular offering, an “event of default” regarding any series of debt securities is any one of the following events:

14

TABLE OF CONTENTS

•

default for 30 days in the payment of any interest installment when due and payable;

​

•

default in the making of any sinking fund payment when due;

​

•

default in the payment of principal or premium (if any) when due at its stated maturity;

​

•

default in the performance, or breach, of any covenant or warranty in the debt securities of that series or in the applicable indenture for 90 days after written notice to us by the trustee or by the holders of at least 25% in principal amount of the outstanding debt securities of that series;

​

•

certain events of bankruptcy, insolvency and reorganization; and

​

•

any other event of default provided with respect to that series of debt securities.

​

We are required to file every year with each trustee an officers’ certificate stating whether any default exists and specifying any default that exists.

Acceleration of Maturity

Unless otherwise described in the prospectus supplement relating to a particular offering, if an event of default has occurred and is continuing with respect to debt securities of a particular series (except defaults relating to bankruptcy events), the trustee or the holders of not less than 25% in principal amount of outstanding debt securities of that series may declare the principal amount of outstanding debt securities of that series, together with accrued and unpaid interest, due and payable immediately. Events of default relating to bankruptcy events will automatically cause the principal amount of outstanding debt securities, together with accrued and unpaid interest, to be due and payable immediately.

Unless otherwise described in the prospectus supplement relating to a particular offering, at any time after a declaration of acceleration of maturity with respect to debt securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the trustee, the holders of a majority in principal amount of the outstanding debt securities of that series by written notice to us and the trustee, may rescind and annul the declaration and its consequences if:

a.

we have paid or deposited with the trustee a sum sufficient to pay:

​

•

all overdue interest on all outstanding debt securities of that series and any related coupons,

​

•

all unpaid principal of and premium, if any, on any of the debt securities which has become due otherwise than by the declaration of acceleration, and interest on the unpaid principal at the rate or rates prescribed in the debt securities,

​

•

to the extent lawful, interest on overdue interest at the rate or rates prescribed in the debt securities, and

​

•

all sums paid or advanced by the trustee and the reasonable compensation, expenses, disbursements and advances of the trustee, its agents and counsel; and

​

b.

all events of default with respect to debt securities of that series, other than the non-payment of amounts of principal, interest or any premium on the debt securities which have become due solely by the declaration of acceleration, have been cured or waived.

​

No rescission will affect any subsequent default or impair any right consequent thereon.

Waiver of Defaults

Unless otherwise described in the prospectus supplement relating to a particular offering, the holders of not less than a majority in principal amount of the outstanding debt securities of any series may, on behalf of the holders of all the debt securities of the series and any related coupons, waive any past default under the applicable indenture with respect to the series and its consequences, except a default:

•

in the payment of the principal of or premium, if any, or interest on any debt security of the series;

​

•

to the extent applicable, relating to any failure to convert any convertible debt securities into common stock on request; or

​

15

TABLE OF CONTENTS

•

in respect of a covenant or provision that cannot be modified or amended without the consent of the holder of each outstanding debt security of the series affected thereby.

​

If an event of default with respect to debt securities of a particular series occurs and is continuing, the trustee will not be obligated to exercise any of its rights or powers under the applicable indenture at the request or direction of any of the holders of debt securities of the series, unless the holders have offered to the trustee reasonable indemnity and security against the costs, expenses and liabilities that might be incurred by it in compliance with the request.

The holders of a majority in principal amount of the outstanding debt securities of any series have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee under the applicable indenture, or exercising any trust or power conferred on the trustee with respect to the debt securities of that series. The trustee may refuse to follow directions in conflict with law or the indenture that may expose the trustee to personal liability or may be unduly prejudicial to the other, non-directing holders. Additionally, the trustee may take any other action the trustee deems proper which is not inconsistent with the direction.

Modification of Indenture

We and the trustee may, without the consent of any holders of debt securities, enter into supplemental indentures for various purposes, including:

•

to evidence the succession of another entity to us and the assumption by the successor of our covenants and obligations under the debt securities and the indenture;

​

•

establishing the form or terms of any series of debt securities issued under the supplemental indentures;

​

•

adding to our covenants for the benefit of the holders or to surrender any of our rights or powers under the indenture;

​

•

adding additional events of default for the benefit of the holders;

​

•

to change or eliminate any provisions of the indenture provided that the change or elimination becomes effective only when there is no debt security outstanding entitled to the benefit of any changed or eliminated provision;

​

•

to secure the debt securities;

​

•

add or provide for a guaranty of any debt security or additional obligors on any debt security;

​

•

to cure any ambiguities or correct or supplement defective or inconsistent provisions of the indenture, provided that holders of debt securities are not materially affected by the change;

​

•

to evidence and provide for acceptance of a successor trustee; and

​

•

to comply with the requirements of the Trust Indenture Act.

​

We and the trustee may, with the consent of the holders of not less than a majority in principal amount of the outstanding debt securities of all affected series acting as one class, execute supplemental indentures adding any provisions to or changing or eliminating any of the provisions of the indenture or modifying the rights of the holders of the debt securities of the series. Without the consent of the holders of all the outstanding debt securities affected thereby, no supplemental indenture may:

•

change the stated maturity of the principal of, or any installment of principal of or interest on, any debt security;

​

•

reduce the principal amount of, the rate of interest on or any premium payable upon the redemption of, or change the manner of calculating the rate of interest on, any debt security;

​

•

reduce the amount of the principal of any original issue discount security that would be due and payable upon acceleration of the maturity of the debt security;

​

•

change the place of payment where, or the currency in which, principal or interest on any debt security is payable;

​

16

TABLE OF CONTENTS

•

impair the right to institute suit for enforcement of payments;

​

•

reduce the percentage in principal amount of the outstanding debt securities of any series, the holders of which must consent to a supplemental indenture or any waiver of compliance with various provisions of, or defaults and covenants under, the indenture; or

​

•

modify any of the provisions described in this section.

​

Consolidation, Merger and Sale of Assets

Unless otherwise described in the prospectus supplement relating to a particular offering, as provided in the indentures, we may not consolidate with or merge into any other person, or convey, transfer or lease all or substantially all of our assets to any other person, unless:

•

the person surviving or formed by the transaction is organized and validly existing under the laws of any U.S. jurisdiction and expressly assumes our obligations under the debt securities and the indentures;

​

•

immediately after giving effect to the transaction, no event of default will have occurred and be continuing under the indentures; and

​

•

the trustees under the indentures receive certain officers’ certificates and opinions of counsel.

​

Satisfaction and Discharge

We may terminate our obligations with respect to debt securities of any series not previously delivered to the trustee for cancellation when those debt securities:

•

have become due and payable;

​

•

will become due and payable at their stated maturity within one year; or

​

•

are to be called for redemption within one year under arrangements satisfactory to the indenture trustee for giving notice of redemption.

​

We may terminate our obligations with respect to the debt securities of a series by depositing with the trustee, as trust funds in trust dedicated solely for that purpose, an amount sufficient to pay and discharge the entire indebtedness on the debt securities of that series. In that case, the applicable indenture will cease to be of further effect, and our obligations will be satisfied and discharged with respect to that series (except our obligations to pay all other amounts due under the indenture and to provide certain officers’ certificates and opinions of counsel to the trustee). At our expense, the trustee will execute proper instruments acknowledging the satisfaction and discharge.

The Trustees

Any trustee may be deemed to have a conflicting interest for purposes of the Trust Indenture Act and may be required to resign as trustee if there is an event of default under the applicable indenture and, as more fully described in Section 310(b) of the Trust Indenture Act, one or more of the following occurs:

•

the trustee is a trustee under another indenture under which our securities are outstanding;

​

•

the trustee is a trustee for more than one outstanding series of debt securities under a single indenture;

​

•

we or our affiliates or underwriters hold certain threshold beneficial ownership interest in the trustee;

​

•

the trustee holds certain threshold beneficial ownership interests in us or in securities of ours that are in default;

​

•

the trustee is one of our creditors; or

​

•

the trustee or one of its affiliates acts as an underwriter or agent for us.

​

We may appoint an alternative trustee for any series of debt securities. The appointment of an alternative trustee would be described in the applicable prospectus supplement.

17

TABLE OF CONTENTS

We and our affiliates may engage in transactions with the trustee and its affiliates in the ordinary course of business.

Governing Law

Unless otherwise described in the prospectus supplement relating to a particular offering, each of the indentures are, and the related senior debt securities and subordinated debt securities will be, governed by and construed under the internal laws of the State of New York.

DESCRIPTION OF WARRANTS

We may issue warrants to purchase debt securities, preferred stock or common stock. We may offer warrants separately or together with one or more additional warrants, debt securities, shares of preferred stock or common stock, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. If we issue warrants as part of a unit, the prospectus supplement will specify whether those warrants may be separated from the other securities in the unit prior to the warrants’ expiration date. We may issue the warrants under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all as described in the prospectus supplement. If we issue the warrants under warrant agreements, the warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

We will describe the particular terms of any warrants that we offer in the prospectus supplement relating to those warrants. Those terms may include the following:

•

the specific designation and aggregate number of warrants, and the price at which we will issue the warrants;

​

•

the currency or currency units in which the offering price, if any, and the exercise price are payable;

​

•

​

•

if applicable, the minimum or maximum number of warrants that may be exercised at any one time;

​

•

information with respect to any book-entry procedures;

​

any anti-dilution provision of the warrants;

​

any additional terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

​

Each warrant will entitle the holder thereof to purchase such number of shares of common stock or preferred stock or other securities at the exercise price as will in each case be set forth in, or be determinable as set forth in, the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date set forth in the applicable prospectus supplement. After the close of

19

TABLE OF CONTENTS

business on the expiration date, unexercised warrants will become void. Warrants may be exercised as set forth in the applicable prospectus supplement relating to the warrants offered thereby. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon as practicable, forward the purchased securities. If less than all of the warrants represented by the warrant certificate are exercised, a new warrant certificate will be issued for the remaining warrants.

We may issue, in one or more series, units comprised of shares of our common stock or preferred stock, warrants to purchase common stock or preferred stock, debt securities or any combination of those securities. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security.

We may evidence units by unit certificates that we issue under a separate agreement. We may issue the units under a unit agreement between us and one or more unit agents. If we elect to enter into a unit agreement with a unit agent, the unit agent will act solely as our agent in connection with the units and will not assume any obligation or relationship of agency or trust for or with any registered holders of units or beneficial owners of units. We will indicate the name and address and other information regarding the unit agent in the applicable prospectus supplement relating to a particular series of units if we elect to use a unit agent.

We will describe in the applicable prospectus supplement the terms of the series of units being offered, including: (i) the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately; (ii) any provisions of the governing unit agreement that differ from those described herein; and (iii) any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units.

The other provisions regarding our common stock, preferred stock, warrants and debt securities as described in this section will apply to each unit to the extent such unit consists of shares of our common stock, preferred stock, warrants and/or debt securities.

PLAN OF DISTRIBUTION

We may sell the securities covered by this prospectus from time to time in one or more transactions, including without limitation:

•

to or through underwriters, brokers, or dealers;

​

•

directly to one or more purchasers, including our affiliates;

​

•

in negotiated transactions;

​

•

upon the exercise of rights distributed or issued to our security holders;

​

•

through agents or dealers; or

​

•

through a combination of any of these methods of sale.

​

In addition, we may enter into derivative or other hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. The applicable prospectus supplement may indicate that third parties may sell securities covered by this prospectus and the prospectus supplement, including in short sale transactions, in connection with those derivatives. If so, the third party may use securities we pledge or that are borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in those sale transactions will be an underwriter and, if applicable, will be identified in the prospectus supplement (or a post-effective amendment thereto).

A prospectus supplement with respect to each series of securities will set forth the terms of the offering, including (to the extent applicable):

•

the name or names of any underwriters, dealers, remarketing firms, or agents and the terms of any agreement with those parties, including the compensation, fees, or commissions received by, and the amount of securities underwritten, purchased, or remarketed by, each of them, if any;

​

•

the public offering price or purchase price of the securities and an estimate of the net proceeds to be received by us from any such sale, as applicable;

​

•

any underwriting discounts or agency fees and other items constituting underwriters’ or agents’ compensation;

​

•

the anticipated delivery date of the securities, including any delayed delivery arrangements, and any commissions we may pay for solicitation of any such delayed delivery contracts;

​

•

that the securities are being solicited and offered directly to institutional investors or others;

​

•

any discounts or concessions to be allowed or reallowed or to be paid to agents or dealers; and

​

•

any securities exchange on which the securities may be listed.

​

Any offer and sale of the securities described in this prospectus by us, any underwriters, or other third parties described above may be effected from time to time in one or more transactions, including, without limitation, privately negotiated transactions, either:

•

at a fixed public offering price or prices, which may be changed;

​

•

at market prices prevailing at the time of sale;

​

•

at prices related to prevailing market prices at the time of sale; or

​

•

at negotiated prices.

​

Such sales may be effected:

•

in transactions on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

​

•

in transactions in the over-the-counter market;

​

22

TABLE OF CONTENTS

•

in block transactions in which the broker or dealer so engaged will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction, or in crosses, in which the same broker acts as an agent on both sides of the trade;

​

•

through the writing of options; or

​

•

through other types of transactions.

​

Any dealer may be deemed to be an underwriter, as that term is defined in the Securities Act, of the securities so offered and sold.

In connection with offerings made through underwriters or agents, we may enter into agreements with those underwriters or agents pursuant to which we receive our outstanding securities in consideration for the securities being offered to the public for cash. If underwriters are utilized in the sale of the securities, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers at fixed public offering prices or at varying prices determined by the underwriters at the time of sale.

We may loan or pledge securities to a financial institution or other third party that in turn may sell the loaned securities or, in any event of default in the case of a pledge, sell the pledged securities using this prospectus and the applicable prospectus supplement. That financial institution or third party may transfer its short position to investors in our securities or in connection with a simultaneous offering of other securities covered by this prospectus.

We may solicit offers to purchase the securities covered by this prospectus directly from, and we may make sales of such securities directly to, institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act with respect to any resale of such securities.

The securities may also be offered and sold, if so indicated in a prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms acting as principals for their own accounts or as agents for us.

If indicated in the applicable prospectus supplement, we may sell the securities through agents from time to time. We generally expect that any agent will be acting on a “best efforts” basis for the period of its appointment.

If underwriters are used in any sale of any securities, the securities may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. Unless otherwise stated in a prospectus supplement, the obligations of the underwriters to purchase any securities will be conditioned on customary closing conditions, and the underwriters will be obligated to purchase all of that series of securities, if any are purchased.

Underwriters, dealers, agents, remarketing firms and other third parties described above may at the time of any offering of securities be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments that the underwriters, dealers, agents, and remarketing firms may be required to make. Underwriters, dealers, agents, and remarketing agents may be customers of, engage in transactions with, or perform services in the ordinary course of business for us and/or our affiliates.

Any underwriters to whom securities covered by this prospectus are sold by us for public offering and sale, if any, may make a market in the securities, but those underwriters will not be obligated to do so and may discontinue any market making at any time without notice.

23

TABLE OF CONTENTS

If we so indicate in the prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the prospectus supplement. The prospectus supplement will describe the commission payable for solicitation of those contracts.

Item 15.   Indemnification of Directors and Officers.

Section 145(a) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative (other than an action by or in the right of the corporation), because he or she is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit, or proceeding, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Section 145(b) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending, or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification shall be made with respect to any claim, issue, or matter as to which he or she shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, he or she is fairly and reasonably entitled to indemnity for such expenses that the Court of Chancery or other adjudicating court shall deem proper.

Section 145 of the DGCL further provides that to the extent a director or officer of a corporation has been successful on the merits or otherwise in the defense of any action, suit, or proceeding referred to in Section 145(a) or (b) of the DGCL, or in defense of any claim, issue, or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith; that indemnification provided for by Section 145 of the DGCL shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and the indemnification

II-1

TABLE OF CONTENTS

provided for by Section 145 of the DGCL shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee, or agent and shall inure to the benefit of such person’s heirs, executors, and administrators. Section 145(g) of the DGCL provides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee, or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify the person against such liability under Section 145 of the DGCL.

Section 102(b)(7) of the DGCL provides that a corporation’s certificate of incorporation may contain a provision eliminating or limiting the personal liability of a director or officer to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, provided that such provision shall not eliminate or limit the liability of (i) a director or officer for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (ii) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) a director under Section 174 of the DGCL, (iv) a director or officer for any transaction from which the director or officer derived an improper personal benefit, or (v) an officer in any action by or in the right of the corporation.

Additionally, the registrant’s certificate of incorporation and bylaws limit the liability of the registrant’s directors and officers to the fullest extent permitted by the DGCL and provide that the registrant will indemnify its directors and officers to the fullest extent permitted by the DGCL.

The registrant has entered into and expects to continue to enter into agreements to indemnify its directors, executive officers, and other key employees as determined by the Board. Under the terms of such indemnification agreements, the registrant is required to indemnify each of its directors and officers, to the fullest extent permitted by the Charter, the Bylaws, and the laws of the State of Delaware, as the same may be amended from time to time (but only to the extent that such amendment permits the Company to provide broader indemnification rights than the Charter, Bylaws or the DGCL permitted prior to the adoption of such amendment), if the basis of the indemnitee’s involvement was by reason of the fact that the indemnitee is or was the registrant’s director or officer or was serving at the registrant’s request in an official capacity for another entity. The registrant must indemnify its officers and directors against all reasonable and documented fees, expenses, charges, and other costs of any type or nature whatsoever, including any and all expenses and obligations paid or incurred in connection with investigating, settling, defending, being a witness in, participating in (including on appeal), or preparing to defend, be a witness, or participate in any completed, actual, pending, or threatened action, suit, claim, or proceeding, whether civil, criminal, administrative, or investigative, or establishing or enforcing a right to indemnification under the indemnification agreement. The indemnification agreements also require the registrant, if so requested, to advance all reasonable and documented fees, expenses, charges, and other costs that such director or officer incurred; provided that such person will return any such advance if it is ultimately determined that such person is not entitled to indemnification by the registrant. Any claims for indemnification by the registrant’s directors and officers may reduce its available funds to satisfy successful third-party claims against the registrant and may reduce the amount of money available to the registrant.

The registrant also maintains a general liability insurance policy, which covers certain liabilities of directors and officers of the registrant arising out of claims based on acts or omissions in their capacities as directors or officers.

TABLE OF CONTENTS

Item 17.   Undertakings.

(a)   The undersigned registrant hereby undertakes:

(1)

to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

​

(i)

to include any prospectus required by Section 10(a)(3) of the Securities Act;

​

(ii)

to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act (“Rule 424(b)”) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

​

(iii)

to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

​

provided, however, that clauses (i), (ii) and (iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement;

(2)

that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

​

(3)

to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

​

(4)

that, for the purpose of determining liability under the Securities Act to any purchaser:

​

(i)

each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

​

(ii)

each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration

​

II-4

TABLE OF CONTENTS

statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; and

(5)

that, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

​

(i)

any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424 under the Securities Act;

​

(ii)

any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

​

(iii)

the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of an undersigned registrant; and

​

(iv)

any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

​

(b)   The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)   Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
