AMBAC FINANCIAL GROUP, INC.

 

Ambac, headquartered in New York City, is a holding company whose subsidiaries provide financial guarantee products and other financial services to clients in both the public and private sectors around the world. Ambac was incorporated on April 29, 1991. Ambac provides financial guarantees through its principal operating subsidiary, Ambac Assurance Corporation.

 

Generally, financial guarantee products written by Ambac Assurance guarantee payment when due of the principal of and interest on the guaranteed obligation. In essence, Ambac steps in to make payments if the party responsible for making payments fails to do so.

 

Ambac Assurance has earned triple-A ratings, the highest ratings available from Moody’s Investors Service, Inc. in 1987, Standard & Poor’s Ratings Services in 1979, Fitch, Inc. in 1994 and Rating and Investment Information, Inc. in 1993. Ambac Assurance’s ratings have been periodically affirmed by each of the rating agencies and have never been revised downward or put on review for a possible downgrade. Moody’s and S&P’s ratings were last reaffirmed in 2002. Fitch’s rating was last reaffirmed in 2001, and R&I’s rating was last reaffirmed in 2003. These ratings are an essential part of Ambac Assurance’s ability to provide credit enhancement.

 

Ambac Assurance provides its financial guarantees for a variety of products, including:

 

  ž public finance securities, which include bonds issued by state and local municipalities such as cities, counties, towns and villages, as well as water districts, sewer districts, higher educational institutions, hospitals, transportation authorities, housing authorities and other similar agencies;

 

  ž mortgage-backed securities, which are bonds and notes where investors receive payments out of the interest and principal on the underlying mortgages that back the securities;

 

  ž asset-backed securities, which are bonds and notes where investors receive payments out of cash flows from the underlying accounts receivable, loans, corporate debt or sovereign debt that back the securities; and

 

  ž structured credit derivatives, which are privately negotiated contracts that provide an investor with credit protection against the occurrence of a specific event such as a payment default or bankruptcy relating to an underlying obligation.

Table of Contents

 

Ambac Assurance, which serves the global capital markets, is primarily engaged in guaranteeing public finance securities, mortgage-backed securities and asset-backed securities. Global capital markets include the U.S. financial markets and international markets such as the United Kingdom, Japanese and Australian financial markets. Ambac Assurance is the successor of the founding financial guarantee insurance company, which wrote the first bond insurance policy in 1971.

 

Ambac provides financial services and investment products principally to its financial guarantee clients which include municipalities and their authorities, school districts, health care organizations and asset-backed issuers.

 

Through its financial services subsidiaries, Ambac provides financial and investment products that include:

 

  ž investment agreements, which are contracts between Ambac and a client that provide for the guaranteed return of principal invested and for the payment of interest at a guaranteed rate;

 

  ž interest rate swaps, which are transactions where one party, known as a counterparty, is required to make periodic payments of a fixed amount, calculated by applying a fixed rate to a constant dollar amount, and the other party, also known as a counterparty, is required to make periodic payments of amounts in the same currency, calculated by applying a floating rate to a constant dollar amount;

 

  ž funding conduits, which are special purpose companies that help clients raise funds by issuing notes for the purpose of acquiring financial assets such as trade receivables from the client; and

 

  ž investment advisory and cash management services, which consist of providing investment advice and money management services to school districts, hospitals and health care organizations and municipalities.

 

As a holding company, Ambac Financial Group, Inc. is largely dependent on dividends from Ambac Assurance, its principal operating subsidiary, to pay dividends on its capital stock, to pay principal of and interest on its indebtedness, to pay its operating expenses, and to make capital investments in its subsidiaries. Dividends from Ambac Assurance are subject to certain insurance regulatory restrictions.

 

Our principal executive offices are located at One State Street Plaza, New York, New York 10004 and our telephone number is (212) 668-0340.

 

RATINGS

 

Our outstanding long-term senior debt has ratings of Aa2 and AA from Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services, respectively. A security rating is not a recommendation to buy, sell or hold securities and is subject to revision or withdrawal at any time by the assigning rating organization.

 

USE OF PROCEEDS

 

We intend to use the proceeds from the sale of the debentures for general corporate purposes.

DESCRIPTION OF THE DEBENTURES

 

The following description of the particular terms of the debentures supplements the description of the general terms and provisions of debt securities, including the debentures, set forth in the accompanying prospectus. Reference is made to the accompanying prospectus for a summary of certain additional provisions of the debentures.

 

General

 

We will issue the debentures as a separate series of senior debt securities under an indenture, dated as of August 24, 2001, between Ambac and JPMorgan Chase Bank (formerly known as The Chase Manhattan Bank), as trustee. Capitalized terms not otherwise defined herein shall have the meanings given to them in the accompanying prospectus and the indenture.

 

The aggregate principal amount of the debentures will be limited to $200,000,000, subject to the provisions described below under “—Further Issues”. The debentures will be our unsecured obligations and will rank equally with all of our other unsecured senior indebtedness. The debentures will be effectively subordinated to existing and future liabilities and any preferred equity of our subsidiaries.

 

The debentures will bear interest at the rate of 5.95% per annum. Interest will accrue from February 28, 2003, or from the most recent interest payment date to which we paid or duly provided for interest. We will pay interest on the debentures on March 31st, June 30th, September 30th, and December 31st of each year, beginning on March 31, 2003. Interest payments will be made to the persons or entities in whose names the debentures are registered at the close of business on March 15, June 15, September 15 or December 15, as the case may be, next preceding the relevant interest payment date. Interest will be calculated on the basis of a 360-day year of twelve 30-day months.

 

The debentures will mature on February 28, 2103. We may not redeem the debentures prior to February 28, 2008, except to the extent described below. On or after February 28, 2008, we may redeem the debentures, in whole at any time or in part from time to time, at 100% of their principal amount, plus accrued interest to the date of redemption. We must give not less than 30 nor more than 60 days prior written notice of any redemption. The debentures will not have the benefit of, or be subject to, any sinking fund.

 

The trustee, through its corporate trust office in New York, New York, will act as our paying agent for the debentures. We will make principal and interest payments in respect of the debentures through the trustee. See “—Book-Entry System.”

 

The debentures will be issued only in registered form in denominations of $25 and integral multiples thereof. We expect market makers to trade the debentures in round lots of 100 units (representing $2,500 aggregate principal amount).

 

Conditional Right to Shorten Maturity upon Tax Event

 

We intend to deduct interest paid on the debentures for United States federal income tax purposes. From time to time legislation has been proposed or recommended that, if enacted into law, could eliminate our ability to deduct interest on the debentures. We cannot be sure that tax law changes affecting our ability to deduct interest paid on the debentures will not be enacted in the future, or that any such changes would not apply to debt instruments issued before the date of enactment of any such changes. If a tax event, as defined below, occurs, we will have the right to shorten the maturity of the debentures to the minimum extent required, in the opinion of nationally recognized independent tax counsel, such that we will be able to deduct interest paid on the debentures for United States federal income tax purposes. If tax counsel is unable to render a definite opinion as to the minimum period required, we will have the right to shorten the maturity of the debentures to such minimum

 

S-5


Table of Contents

period as our board of directors may determine in good faith after receiving an opinion of tax counsel regarding the applicable legal standards. We can give no assurance that we will not exercise our right to shorten the maturity of the debentures if a tax event occurs. Likewise, we can give no assurance as to the period to which such maturity would be shortened.

 

If we elect to shorten the maturity of the debentures upon the occurrence of a tax event, we will mail a notice of the shortened maturity to each registered holder of record of the debentures stating the new maturity date of the debentures. We will mail such notice by first-class mail not more than 60 days after the occurrence of such tax event. Such notice will be effective immediately upon mailing.

 

We believe that the debentures should constitute indebtedness for United States federal income tax purposes under current law and, in that case, the shortening of the maturity of the debentures would not be a taxable event to you for such purposes. You should be aware, however, that the shortening of the maturity of the debentures will be a taxable event to you if, prior to such shortening, the debentures were to be treated as equity for United States federal income tax purposes.

 

“Tax event” means the receipt by us of an opinion of tax counsel to the effect that, as a result of the occurrence of any of the following events on or after February 28, 2003, there is more than an insubstantial increase in the risk that interest paid by us on the debentures is not, or will not be, deductible, in whole or in part, by us for federal income tax purposes:

 

  ž any amendment to, clarification of, or change, including any announced prospective amendment, clarification or change, in any law, or any regulations of the United States,

 

  ž any judicial decision, official administrative pronouncement, ruling, regulatory procedure, notice or announcement, including any notice or announcement of intent to adopt or promulgate any ruling, regulatory procedure or regulation, and including the issuance of proposed regulations, or

 

  ž any amendment to, clarification of, or change in any official position with respect to, or any interpretation of, an administrative or judicial action or law or regulation of the United States that differs from the position or interpretation that was previously generally accepted.

 

We are not addressing any considerations, including any United States or foreign tax considerations, that may be applicable to an investment in the debentures by a person who is not a citizen or a tax resident of the United States.

 

Optional Redemption Upon Tax Event

 

If a tax event occurs and, in the opinion of nationally recognized independent tax counsel, there would, notwithstanding the shortening of the maturity of the debentures, be more than an insubstantial risk that interest paid by us on the debentures is not or will not be deductible, in whole or in part, by us for United States federal income tax purposes, we will have the right, within 90 days following the occurrence of such tax event, to redeem the debentures in whole, but not in part, at 100% of their principal amount, plus accrued interest to the date of redemption. We must give not less than 30 nor more than 60 days prior written notice of any redemption.

 

Book-Entry System

 

The following are summaries of certain rules and operating procedures of DTC that affect the payment of principal and interest and the transfers of interests in the global debentures. Upon issuance, the debentures will be issued only in the form of one or more definitive global securities which will be deposited with, or on behalf of, DTC and registered in the name of Cede & Co., as nominee of DTC. Unless and until it is exchanged in whole or in part for debentures in definitive form under the limited circumstances described below, a global debenture may not be transferred except as a whole (1) by DTC to a nominee, (2) by a nominee of DTC to DTC or another nominee of DTC or (3) by DTC or any such nominee to a successor of DTC or a nominee of such successor.

 

S-6


Table of Contents

 

Ownership of beneficial interests in a global debenture will be limited to persons that have accounts with DTC for such global debenture, participants, or persons that may hold interests through participants. Upon the issuance of a global debenture, DTC will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal amounts of the debentures represented by such global debenture beneficially owned by such participants. Ownership of beneficial interests in the global debentures will be shown on, and the transfer of such ownership interests will be effected only through, records maintained by DTC, with respect to interests of participants. The laws of some states may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may limit or impair the ability to own, transfer or pledge beneficial interests in the global debentures.

 

So long as DTC or its nominee is the registered owner of a global debenture, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the debentures represented by such global debenture for all purposes under the indenture. Except as set forth below, owners of beneficial interests in a global debenture will not be entitled to have debentures represented by such global debenture registered in their names, will not receive or be entitled to receive physical delivery of such debentures in certificated form and will not be considered the registered owners or holders thereof under the indenture. Accordingly, each person owning a beneficial interest in a global debenture must rely on the procedures of DTC and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the indenture. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a global debenture desires to give or take any action that a holder is entitled to give or take under the indenture, DTC would authorize the participants holding the relevant beneficial interests to give or take such action, and such participants would authorize beneficial owners owning through such participants to give or to take such action or would otherwise act upon the instructions of beneficial owners holding through them.

 

Principal and interest payments on interests represented by a global debenture will be made to DTC or its nominee, as the case may be, as the registered owner of such global debenture. None of Ambac, the trustee or any other agent of Ambac or agent of the trustee will have any responsibility or liability for any facet of the records relating to or payments made on account of beneficial ownership of interests. We expect that DTC, upon receipt of any payment of principal or interest in respect of a global debenture, will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in such global debenture as shown on the records of DTC. We also expect that payments by participants to owners of beneficial interests in the global debentures held through such participants will be governed by standing customer instructions and customary practice, as is now the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be responsibility of such participants.

 

If DTC is at any time unwilling, unable or ineligible to continue as depositary for the debentures, and we fail to appoint a successor depository registered as a clearing agency under the Securities Exchange Act of 1934 within 90 days, we will issue debentures in definitive form in exchange for the respective global debentures. Any debentures issued in definitive form in exchange for the global debentures will be registered in such name or names, and will be issued in denominations of $25 and integral multiples of $25, as DTC shall instruct the trustee. It is expected that such instructions will be based upon directions received by DTC from participants with respect to ownership of beneficial interests in the global debentures.

 

DTC is a limited purpose trust company organized under the Banking Law of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC was created to hold the securities of its participants and to facilitate the clearance and settlement of transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of which, and/or their representatives, own DTC. Access to the DTC book-entry system is

 

S-7


Table of Contents

also available to others, such as banks, brokers and dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

 

Same-Day Settlement and Payment

 

Settlement for the debentures will be made by the underwriters in immediately available funds. All payments of principal and interest in respect of the debentures will be made by us in immediately available funds.

 

The debentures will trade in DTC’s Same-Day Funds Settlement System until maturity and secondary market trading activity in the debentures will settle in immediately available funds. No assurance can be given as to the effect, if any, of settlement in immediately available funds on trading activity in the debentures.

 

Further Issues

 

We may from time to time, without notice to or the consent of the registered holders of the debentures, create and issue further debt securities ranking pari passu with the debentures in all respects, or in all respects except for the payment of interest accruing prior to the issue date of such further debt securities or except for the first payment of interest following the issue date of such further debt securities, and so that such further debt securities may be consolidated and form a single series with the debentures offered hereby and have the same terms as to status, redemption or otherwise as the debentures offered hereby.

 

Additional Terms

 

For additional important information about the debentures, see “Description of Debt Securities” in the accompanying prospectus. That information includes:

 

  ž additional information on the terms of the debentures;

 

  ž general information on the indenture and trustee;

 

  ž a description of the limitation on consolidation, merger and sale of assets; and

 

  ž a description of events of default under the indenture.

 

Ambac’s Relationship With the Trustee

 

The trustee under the indenture, JPMorgan Chase Bank, formerly known as The Chase Manhattan Bank, occasionally acts as trustee in connection with obligations insured by Ambac and its subsidiaries. JPMorgan Chase Bank is also acting as a trustee in connection with certain debt obligations that were previously issued by us. In addition, we have various business dealings with J.P. Morgan Securities Inc., an affiliate of the trustee.

The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the debentures are subject to, among other things, the approval of certain legal matters by their counsel and certain other conditions. The underwriters are obligated to take and pay for all the debentures if any are taken.

 

The underwriters propose initially to offer part of the debentures to the public at the public offering price set forth on the cover page of this prospectus supplement and in part to certain dealers at prices that represent a concession not in excess of 0.50% of the principal amount of the debentures. Any underwriter may

 

S-9


Table of Contents

allow, and such dealers may reallow, a concession not in excess of 0.45% of the principal amount of the debentures to certain other dealers. After the initial offering of the debentures, the offering price and other selling terms may from time to time be varied by the underwriters.

 

The debentures are a new issue of securities with no established trading market. We will make application to list the debentures on the New York Stock Exchange. We expect trading of the debentures on the New York Stock Exchange to commence within a 30-day period after the initial delivery of the debentures. The underwriters have advised us that they intend to make a market in the debentures prior to the commencement of trading on the New York Stock Exchange. The underwriters will have no obligation to make a market in the debentures, however, and may discontinue market making activities, if commenced, at any time without notice. We can give no assurance as to the liquidity of the trading market, if any, for the debentures.

 

In order to facilitate the offering of the debentures, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the debentures. Specifically, the underwriters may over-allot in connection with this offering, creating short positions in the debentures for their own account. In addition, to cover over-allotments or to stabilize the price of the debentures, the underwriters may bid for and purchase debentures in the open market. Finally, the underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased debentures sold by or for the account of such underwriter in stabilizing or short covering transactions. Any of these activities may stabilize or maintain the market price of the debentures above independent market levels. The underwriters are not required to engage in these activities and may end any of these activities at any time.

 

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments that the underwriters may be required to make in respect thereof.

 

The underwriters or their affiliates have provided and may in the future continue to provide investment banking and other financial services, including the provision of credit facilities, for us in the ordinary course of business.

 

Each underwriter has represented, warranted and agreed that: (i) it has not offered or sold and, prior to the expiry of a period of six months from the closing date, will not offer or sell any debentures to persons in the United Kingdom except to persons whose ordinary activities involve them in acquiring, holding, managing or disposing of investments (as principal or agent) for the purposes of their businesses or otherwise in circumstances which have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public Offers at Securities Regulations 1995; (ii) it has only communicated or caused to be communicated and will only communicate or cause to be communicated any invitation or inducement to engage in investment activity (within the meaning of section 21 of the Financial Services and Markets Act 2000 (the “FSMA”)) received by it in connection with the issue or sale of any debentures in circumstances in which section 21(1) of the FSMA does not apply to the Issuer; and (iii) it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the debentures in, from or otherwise involving the United Kingdom.

 

Each underwriter has acknowledged and agreed that the debentures have not been registered under the Securities and Exchange Law of Japan and are not being offered or sold and may not be offered or sold, directly or indirectly, in Japan or to or for the account of any resident of Japan, except (i) pursuant to an exemption from the registration requirements of the Securities and Exchange Law of Japan and (ii) in compliance with any other applicable requirements of Japanese law.

 

The debentures may not be offered, sold, transferred or delivered in or from The Netherlands, as part of their initial distribution or as part of any re-offering, and neither this prospectus supplement, the accompanying

AMBAC FINANCIAL GROUP, INC.

 

Ambac, headquartered in New York City, is a holding company whose subsidiaries provide financial guarantee products and other financial services to clients in both the public and private sectors around the world. Ambac was incorporated on April 29, 1991. Ambac provides financial guarantees through its principal operating subsidiary, Ambac Assurance Corporation.

 

Generally, financial guarantee products written by Ambac Assurance in both the primary and secondary markets guarantee payment when due of the principal of and interest on the guaranteed obligation. In essence, Ambac steps in to make payments if the party responsible for making payments fails to do so.

 

Ambac Assurance has earned triple-A ratings, the highest ratings available from Moody’s Investors Service, Inc. in 1987, Standard & Poor’s Rating Services in 1979, Fitch, Inc. in 1994 and Rating and Investment Information, Inc. in 1993. Ambac Assurance’s ratings have been affirmed annually by each of the rating agencies and have never been revised downward or put on review for a possible downgrade. All of these ratings were last reaffirmed in 2000. These ratings are an essential part of Ambac Assurance’s ability to provide credit enhancement.

 

Ambac Assurance provides its financial guarantees for a variety of products, including:

 

  ž municipal securities, which include bonds issued by state and local municipalities such as cities, counties, towns and villages, as well as water districts, sewer districts, higher educational institutions, hospitals, transportation authorities, housing authorities and other similar agencies;

 

  ž mortgage-backed securities, which are bonds and notes where investors receive payments out of the interest and principal on the underlying mortgages that back the securities; and

 

  ž asset-backed securities, which are bonds and notes where investors receive payments out of cash flows from the underlying accounts receivable, loans, corporate debt or sovereign debt that back the securities; and

 

  ž structured credit derivatives, which are privately negotiated contracts that provide an investor with credit protection against the occurrence of a specific event such as a payment default or bankruptcy relating to an underlying obligation.

 

Ambac Assurance, which serves the global capital markets, is primarily engaged in guaranteeing municipal securities, mortgage-backed securities and asset-backed securities. Global capital markets include the U.S. financial markets and international markets such as the United Kingdom, Japanese and Australian financial markets. Ambac Assurance is the successor of the founding financial guarantee insurance company, which wrote the first bond insurance policy in 1971.

 

Ambac Assurance seeks to minimize the risk inherent in its financial guarantee portfolio by maintaining a diverse portfolio which spreads its risk across a number of criteria, including issue size, type of bond,

geographic area and obligor, which is the entity responsible for making payments. In the case of default on a guaranteed obligation, payments under the financial guarantee policy generally may not be accelerated by the policyholder without Ambac Assurance’s consent. As of December 31, 2000, Ambac Assurance’s net financial guarantee in force, after giving effect for reinsurance, was $418.4 billion.

 

Ambac Credit Products, LLC, a wholly owned subsidiary of Ambac Assurance, provides credit protection in the global markets in the form of structured credit derivatives. Structured credit derivatives are privately negotiated contracts that require Ambac Credit to make payments upon the occurrence of certain defined credit events relating to an underlying obligation; generally a fixed income obligation. Structured credit derivatives issued by Ambac Credit are guaranteed by Ambac Assurance. Ambac Credit generally enters into structured credit derivative contracts in which its exposure is to highly rated risks.

 

Ambac provides financial services and investment products principally to its financial guarantee clients which include municipalities and their authorities, school districts, health care organizations and asset-backed issuers.

 

Through its financial services subsidiaries, Ambac provides financial and investment products including:

 

  ž investment agreements, which are contracts between Ambac and a client that provide for the guaranteed return of principal invested and for the payment of interest at a guaranteed rate;

 

  ž interest rate swaps, which are transactions where one party, known as a counterparty, is required to make periodic payments of a fixed amount, calculated by applying a fixed rate to a constant dollar amount, and the other party, also known as a counterparty, is required to make periodic payments of amounts in the same currency, calculated by applying a floating rate to a constant dollar amount;

 

  ž funding conduits, which are special purpose companies that help clients raise funds by issuing notes for the purpose of acquiring financial assets such as trade receivables from the client; and

 

  ž investment advisory and cash management services, which consist of providing investment advice and money management services to school districts, hospitals and health care organizations and municipalities.

 

We conduct our investment agreement business through our subsidiary, Ambac Capital Funding, Inc. Ambac Capital provides investment agreements primarily to municipalities and their authorities, mortgage-backed security issuers, asset-backed security issuers and international issuers. The investment agreements written by Ambac Capital are guaranteed by Ambac Assurance. Investment agreements are primarily used by issuers to invest bond proceeds until the proceeds can be used for their intended purpose.

 

Ambac provides interest rate swaps through its subsidiary, Ambac Financial Services, L.P., primarily to states, municipalities and their authorities, and other entities in connection with their financings. The interest rate swaps provided by Ambac Financial Services are guaranteed by Ambac Assurance and provide a financing alternative that is intended to reduce an issuer’s overall borrowing costs and/or help manage their interest rate risk.

 

Ambac provides investment advisory, cash management and fund administration services through its subsidiary, Cadre Financial Services, Inc., and broker/dealer services through its subsidiary, Cadre Securities, Inc., primarily to school districts, hospitals and health care organizations, and municipalities.

 

As a holding company, Ambac Financial Group, Inc. is largely dependent on dividends from Ambac Assurance, its principal operating subsidiary, to pay dividends on its capital stock, to pay principal of and interest on its indebtedness, to pay its operating expenses, and to make capital investments in its subsidiaries. Dividends from Ambac Assurance are subject to certain insurance regulatory restrictions.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

 

This prospectus and accompanying prospectus supplement may contain or incorporate by reference information that includes or is based upon forward-looking statements within the meaning of the Securities Litigation Reform Act of 1995. Forward-looking statements give Ambac’s expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current facts and relate to future operating or financial performance.

 

Any or all of our forward-looking statements here or in other publications may turn out to be wrong and are based on current expectations and the current economic environment. Ambac’s actual results may vary materially, and there are no guarantees about the performance of our securities. Among factors that could cause actual results to differ materially are:

 

  ž changes in the economic, credit or interest rate environment in the United States and abroad;

 

  ž the level of activity within the national and worldwide debt markets;

 

  ž competitive conditions and pricing levels;

 

  ž legislative and regulatory developments;

 

  ž changes in tax laws; and

 

  ž other risks and uncertainties that have not been identified at this time.

 

Ambac is not obligated to publicly correct or update any forward-looking statement if we later become aware that it is not likely to be achieved, except as required by law. You are advised, however, to consult any further disclosures we make on related subjects in our reports to the SEC.

We computed the ratio of earnings to fixed charges by dividing earnings before income taxes and extraordinary items plus fixed charges by the fixed charges. For the purpose of this ratio, fixed charges consist of interest expense incurred, capitalized interest, amortization of debt expense and one-third of rental payments under operating leases, an amount deemed representative of the appropriate interest factor. Since we did not have any preferred stock outstanding during the periods indicated above, our ratio of earnings to combined fixed charges and preference dividends for each relevant period will be the same as our ratio of earnings to fixed charges.

Table of Contents

DESCRIPTION OF SECURITIES

 

This prospectus contains a summary of the common stock, preferred stock and debt securities that we may sell. These summaries are not meant to be a complete description of each security. However, this prospectus and accompanying prospectus supplement contain all the material terms of the securities being offered.

 

DESCRIPTION OF CAPITAL STOCK

 

Our authorized capital stock consists of 200,000,000 shares of common stock, par value $0.01 per share, and 4,000,000 shares of preferred stock, par value $0.01 per share. No shares of preferred stock were issued or outstanding as of March 15, 2001.

 

Common stock

 

Voting rights.    Each holder of common stock is entitled to one vote for each share held on all matters to be voted upon by stockholders.

 

Dividends.    The holders of common stock, after any preferences of holders of any preferred stock, are entitled to receive dividends as determined by the board of directors.

 

Liquidation and dissolution.    If we liquidate or dissolve, the holders of the common stock will be entitled to share in our assets available for distribution to common stockholders in proportion to the amount of common stock they own. The amount available for common stockholders is calculated after payment of liabilities. Holders of any preferred stock will receive a preferential share of our assets before the holders of the common stock receive any assets.

 

Other rights.    Holders of the common stock have no right to

 

  ž convert or exchange the stock into any other security;

 

  ž have the stock redeemed; or

 

  ž purchase additional stock or to maintain their proportionate ownership interest.

 

The common stock does not have cumulative voting rights. Holders of shares of our common stock are not required to make additional capital contributions.

 

Our common stock is listed and traded on the New York Stock Exchange under the symbol “ABK.”

 

Directors’ liability

 

Our amended and restated certificate of incorporation provides that, to the fullest extent permitted under Delaware law, a member of the board of directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duty as a director.

 

Our amended and restated certificate of incorporation allows us to indemnify directors and officers. We also maintain a directors’ and officers’ liability insurance policy.

 

Transfer agent and registrar

 

Citibank, N.A. is the transfer agent and registrar for the common stock.

Table of Contents

 

Removal of directors by stockholders.    Delaware law provides that members of a board of directors may be removed, with or without cause, by a majority of the outstanding shares entitled to vote on the election of the directors.

 

Stockholder nomination of directors.    Our by-laws provide that a stockholder must notify us in writing of any stockholder nomination of a director at least sixty, but not more than ninety, days prior to the date of the meeting for the election of directors. Except that if we give less than seventy days notice or prior public disclosure of the date for the meeting, then notice by a stockholder is timely if received by us no later than the close of business on the tenth day on which such notice was mailed or such public disclosure was made.

 

10% stockholder provision.    Our subsidiary, Ambac Assurance, is a Wisconsin corporation and subject to the insurance and regulatory laws of the State of Wisconsin. Under Wisconsin insurance holding company laws, any acquisition of control of Ambac requires the prior approval of the Office of the Commissioner of Insurance of the State of Wisconsin. As a result, section 4.5 of our amended and restated certificate of incorporation provides that no stockholder may cast votes with respect to 10% or more of our voting stock, regardless of the actual number of shares of voting stock beneficially held by the stockholder. In addition, any voting stock held by a stockholder in excess of 10% will not count in the calculation of or toward a quorum at any meeting of stockholders. These voting restrictions will not apply to any stockholder whose acquisition or ownership of 10% or more of our voting stock has been approved by the Wisconsin Insurance Commissioner.

 

Delaware Business Combination Statute.    Section 203 of the Delaware General Corporation Law is applicable to us. Section 203 of the DGCL restricts some types of transactions and business combinations between a corporation and a 15% stockholder. A 15% stockholder is generally considered by Section 203 to be a person owning 15% or more of the corporation’s outstanding voting stock. Section 203 refers to a 15% stockholder as an “interested stockholder.” Section 203 restricts these transactions for a period of three years from the date the stockholder acquired 15% or more of our outstanding voting stock. With some exceptions, unless the transaction is approved by the board of directors and the holders of at least two-thirds of the outstanding voting stock of the corporation, Section 203 prohibits significant business transactions such as:

 

  ž a merger with, disposition of significant assets to or receipt of disproportionate financial benefits by the 15% stockholder, or

 

  ž any other transaction that would increase the 15% stockholder’s proportionate ownership of any class or series of our capital stock.

 

The shares held by the 15% stockholder are not counted as outstanding when calculating the two-thirds of the outstanding voting stock needed for approval.

 

The prohibition against these transactions does not apply if:

 

  ž prior to the time that any stockholder became a 15% stockholder, the board of directors approved either the business combination or the transaction in which such stockholder acquired 15% or more of our outstanding voting stock, or

 

  ž the 15% stockholder owns at least 85% of the outstanding voting stock of the corporation as a result of the transaction in which such stockholder acquired 15% or more of our outstanding voting stock. Shares held by persons who are both directors and officers or by some types of employee stock plans are not counted as outstanding when making this calculation.

 

Stockholders rights plan

 

Under Delaware law, a corporation may create and issue rights entitling the holders of such rights to purchase from the corporation shares of its capital stock of any class or classes, unless prohibited by its certificate of incorporation. The price and terms of these shares must be stated in the certificate of incorporation or in a resolution adopted by the board of directors.

Table of Contents

 

We have entered into a stockholder rights agreement. As with most stockholder rights agreements, the terms of our rights agreement are complex and not easily summarized, particularly as they relate to the acquisition of our common stock and to exercisability of the rights. This summary may not contain all of the information that is important to you. Accordingly, you should carefully read our rights agreement, which is incorporated by reference into this prospectus in its entirety.

 

Our rights agreement provides that each share of our common stock outstanding will initially have attached to it the right to purchase one one-hundredth of a Series A junior participating preferred share of Ambac. As a result of stock splits effected since the adoption of our stockholders rights agreement, each share of common stock presently has attached to it one-third of a share. The purchase price per one one-hundredth of a share of preferred stock is $190, but this amount may be adjusted in some circumstances.

 

Initially, the rights are attached to all common stock certificates representing shares then outstanding, and no separate rights certificates will be distributed. The rights will separate from the common stock and a distribution date will occur upon the earlier of

 

  (a) 10 days following a public announcement that a person or group of affiliated or associated persons, known as an acquiring person, has acquired, or obtained the right to acquire, beneficial ownership of 20% or more of the outstanding shares of common stock or, with respect to persons that beneficially own 15% or more of the outstanding shares of common stock on January 31, 1996, such person has acquired, or obtained the right to acquire, beneficial ownership of 25% or more of the outstanding shares of common stock, or

 

  (b) 10 business days, or such later date as the board shall determine, following the commencement of a tender offer or exchange offer that would result in a person or group becoming an acquiring person.

 

Until the distribution date the rights will be evidenced by the common stock certificates and will be transferred with and only with such common stock certificates, new common stock certificates issued after the record date will contain a notation incorporating the rights agreement by reference and the surrender for transfer of any certificates for common stock outstanding will also constitute the transfer of the rights associated with the common stock represented by such certificate.

 

The rights are not exercisable until the distribution date and will expire at the close of business on January 31, 2006, unless earlier redeemed or exchanged by Ambac as described below.

 

As soon as practicable after the distribution date, rights certificates will be mailed to holders of record of the common stock as of the close of business on the distribution date and, thereafter, the separate rights certificates alone will represent the rights. Except as otherwise determined by the board, only shares of common stock issued prior to the distribution date will be issued with rights.

 

In the event that a person becomes an acquiring person, except pursuant to an offer for all outstanding shares of common stock that the independent directors determine to be fair to and otherwise in the best interests of Ambac and its stockholders, each holder of a right will then have the right to receive, upon exercise, common stock having a value equal to two times the exercise price of the right. Following the occurrence of the event set forth in this paragraph, all rights that are, or were, beneficially owned by any acquiring person will be null and void.

 

In the event that, at any time following the stock acquisition date,

 

  (a) Ambac is acquired in a merger or other business combination transaction in which Ambac is not the surviving corporation, other than a merger which follows an offer described in the preceding paragraph, or

 

  (b) fifty percent (50%) or more of Ambac’s assets, cash flow or earning power is sold or transferred,

 

8


Table of Contents

each holder of a right shall thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the right.

 

At any time after a person becomes an acquiring person and prior to the acquisition by such person or group of 50% or more of the outstanding common stock, the board may exchange the rights, other than rights owned by such person or groups which have become void, in whole or in part, at an exchange ratio of three shares of common stock, or one one-hundredth of a share of preferred stock, per right, subject to adjustment.

 

At any time until 10 days following the stock acquisition date, Ambac may redeem the rights in whole, but not in part, at a price of $.01 per right. Immediately upon the action of the board ordering redemption of the rights, the rights will terminate and the only right of the holders of rights will be to receive the $.01 redemption price.

 

Any of the provisions of the rights agreement may be amended by the board prior to the distribution date. After the distribution date, the provisions of the rights agreement may be amended by the board in order to cure any ambiguity, to make changes which do not adversely affect the interests of holders of rights, or to shorten or lengthen any time period under the rights agreement; however, no amendment may be made at the time when the rights are not redeemable.

 

The rights may have certain anti-takeover effects. The rights will cause substantial dilution to a person or group that attempts to acquire Ambac in a manner which causes the rights to become discount rights unless the offer is conditional on a substantial number of rights being acquired. The rights, however, should not affect any prospective offeror willing to make an offer at a fair price and otherwise in the best interests of Ambac and its stockholders as determined by a majority of the directors who are not affiliated with the person making the offer, or willing to negotiate with the board. The rights should not interfere with any merger or other business combination approved by the board since the board may, at its option, at any time until ten days following the stock acquisition date redeem all but not less than all the then outstanding rights at the redemption price.

 

The terms of our amended and restated certificate of incorporation and by-laws are complex and not easily summarized. The above summary may not contain all of the information that is important to you. Accordingly, you should carefully read our amended and restated certificate of incorporation and by-laws, which are incorporated by reference into this prospectus in their entirety.

 

Preferred stock

 

General.    We are authorized to issue 4,000,000 shares of preferred stock. No shares of preferred stock are currently issued or outstanding. However, shares of preferred stock designated as Series A junior participating preferred stock are authorized and reserved for issuance in connection with the rights agreement described above. Our board of directors may, without stockholder approval, issue shares of preferred stock. The board can issue more than one series of preferred stock. The board has the right to fix the number of shares, dividend rights, conversion rights, voting rights, redemption rights, liquidation preferences and any other rights, preferences, privileges and restrictions applicable to the preferred stock it decides to issue.

 

Voting rights.     The DGCL provides that the holders of preferred stock will have the right to vote separately as a class on any proposal involving fundamental changes in the rights of holders of such preferred stock.

 

Conversion or exchange.    The prospectus supplement will describe the terms, if any, on which the preferred stock may be convertible into or exchangeable for our common stock, debt securities or other preferred stock. These terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. These provisions may allow or require the number of our shares of common stock or other securities to be received by the holders of preferred stock to be adjusted.

DESCRIPTION OF DEBT SECURITIES

 

The debt securities will be issued under an indenture, dated as of August 24, 2001, between Ambac and The Chase Manhattan Bank, which serves as the trustee under the indenture.

General

 

The debt securities will be our direct unsecured general obligations. The debt securities will rank equally with all of our other debt.

 

Because we are a holding company, our rights and the rights of our creditors, including the holders of debt securities, to participate in the assets of any subsidiary upon its liquidation or recapitalization will be subject to the prior claims of the subsidiary’s creditors, except to the extent that we may ourself be a creditor with recognized claims against the subsidiary.

 

A prospectus supplement relating to any series of debt securities being offered will include specific terms relating to the offering. The prospectus supplement will include some or all of the following for a particular series of debt securities:

 

  ž the title of debt securities;

 

  ž any limit on the aggregate principal amount of the debt securities;

 

  ž the price or prices at which we will sell the debt securities;

  ž the per annum interest rate or rates, if any, on the series and the date or dates from which any such interest will accrue;

 

  ž whether the amount of payments of principal of and premium, if any, or interest on the debt securities may be determined with reference to any index, formula or other method, such as one or more currencies, commodities, equity indices or other indices, and the manner of determining the amount of such payments;

 

  ž the dates on which we will pay interest on the debt securities and the regular record date for determining who is entitled to the interest payable on any interest payment date;

 

  ž the place or places where the principal of and premium, if any, and interest on the debt securities will be payable;

 

  ž if we possess the option to do so, the periods within which and the prices at which we may redeem the debt securities, in whole or in part, pursuant to optional redemption provisions, and the other terms and conditions of any such provisions;

 

  ž our obligation, if any, to redeem, repay or purchase debt securities by making periodic payments to a sinking fund or through an analogous provision or at the option of holders of the debt securities, and the period or periods within which and the price or prices at which we will redeem, repay or purchase the debt securities, in whole or in part, pursuant to such obligation, and the other terms and conditions of such obligation;

 

  ž the denominations in which the debt securities will be issued, if other than $1,000 and integral multiples of $1,000;

Table of Contents

 

  ž the portion or methods of determining the portion of the principal amount of the debt securities which we must pay upon the acceleration of the maturity of the debt securities in connection with an Event of Default, as described below, if other than the full principal amount;

 

  ž the currency, currencies or currency unit in which we will pay the principal of and premium, if any or interest, if any, on the debt securities, if not United States dollars,

 

  ž provisions, if any, granting special rights to holders of the debt securities upon the occurrence of specified events;

 

  ž any deletions from, modifications of or additions to the Events of Default or our covenants with respect to the applicable series of debt securities, and whether or not such Events of Default or covenants are consistent with those contained in the indenture;

  ž any trustees, authenticating or paying agents, transfer agents or registrars or other agents with respect to the debt securities; and

 

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

 

Restrictive Covenants

 

Unless we tell you otherwise in an accompanying prospectus supplement, the following restrictive covenants shall apply to each series of debt securities:

 

Limitation on Liens.    So long as any debt securities are outstanding, neither Ambac nor any of its subsidiaries will create, incur or guarantee any debt which is secured by any mortgage, pledge, lien, security interest or other encumbrance on any capital stock of Ambac Assurance, any successor to the business of Ambac Assurance which is also a subsidiary of Ambac or any corporation, other than Ambac, having direct or indirect control of Ambac Assurance or any such successor. However, this restriction will not apply if the debt securities then outstanding are secured at least equally and ratably with the otherwise prohibited secured debt so long as it is outstanding.

 

Limitations on Dispositions of Stock of Certain Subsidiaries.    So long as any debt securities are outstanding and subject to the provisions of the indenture regarding mergers, consolidations and sales of assets, neither Ambac nor any of its subsidiaries will sell or otherwise dispose of any shares of capital stock of Ambac Assurance, any successor to the business of Ambac Assurance which is also a subsidiary of Ambac or any corporation, other than Ambac, having direct or indirect control of Ambac Assurance or any such successor, except for:

 

  ž a sale or other disposition of any of such stock to a wholly-owned subsidiary of Ambac or of such subsidiary;

 

  ž a sale or other disposition of all of such stock for at least fair value, as determined by Ambac’s board of directors acting in good faith, or

 

  ž a sale or other disposition of any of such stock for at least fair value, as determined by Ambac’s board of directors acting in good faith, if, after such transaction, Ambac and its subsidiaries would own more than 80% of the issued and outstanding voting stock of Ambac Assurance or any such successor.

Consolidation, Merger, Sale of Assets and Other Transactions

 

Under the indenture, so long as any debt securities are outstanding, we may not consolidate or merge with another corporation or convey, transfer or lease its properties or assets as an entirety or substantially as an entirety to another person, unless:

 

  ž the successor or purchaser is a corporation organized under the laws of the United States, any state within the United States or the District of Columbia;

 

  ž the successor or purchaser expressly assumes our obligations under the indenture and the debt securities; and

 

  ž immediately after the transaction, no Event of Default, and no event which, if notice was given and/or a certain period of time passed, would become an Event of Default, shall exist.

 

Except as described above, neither the indenture nor the debt securities contain change of control or similar provisions intended to protect you by requiring us to repurchase or redeem the debt securities if we become involved in a merger or other significant corporate event. In addition, except as described above, no indenture provisions prohibit us from entering into a merger or a significant corporate event.

 

Events of Default

 

Unless we tell you otherwise in an accompanying prospectus supplement, the following shall constitute “Events of Default” under the indenture with respect to each series of debt securities:

 

  ž our failure for 30 days to pay any interest on any debt security of such series when due;

 

  ž our failure to pay principal or premium, if any, on any debt security of such series when due, regardless of whether such payment became due because of maturity, redemption, acceleration or otherwise;

 

  ž our failure to perform any of our covenants with respect to such debt securities for 60 days after we receive notice of such failure; and

 

  ž certain events of bankruptcy, insolvency or reorganization of Ambac, Ambac Assurance or any successor to the business of Ambac Assurance which is also a subsidiary of Ambac.

 

We are required to file with the trustee each year a written statement as to our compliance with certain of our obligations under the indenture.

 

Remedies

 

If an Event of Default resulting from the failure to pay interest or principal or premium, if any, on the debt securities of any series exists, either the trustee or the holders of 25% in aggregate principal amount of outstanding debt securities of such series may declare the principal of all the outstanding debt securities of that series and all accrued interest on those debt securities immediately due.

 

If one of the other Events of Default exists, either the trustee or the holders of 25% in aggregate principal amount of the outstanding debt securities of all existing series, voting together as one class, may declare the principal of all the outstanding debt securities of all series and all accrued interest on those debt securities immediately due.

 

Under certain conditions, these declarations may be annulled and defaults which have been cured may be waived by the holders of a majority in aggregate principal amount of the outstanding debt securities of the affected series, voting separately, or of all series, voting together as one class, whichever was required to make the declaration in the first place.

Before the principal of the debt securities of any series is declared immediately due as described above, the holders of a majority in aggregate principal amount of the outstanding debt securities of the affected series, voting separately, or of all series, voting together as one class, depending on the nature of the Event of Default, may waive any Event of Default other than an Event of Default:

 

  ž resulting from a failure to pay principal of and premium, if any, or interest on any of the debt securities or

 

  ž in respect of a provision of the indenture which cannot be modified without the consent of the holder of each debt security affected by the modification.

 

If an Event of Default occurs, the holders of a majority in aggregate principal amount of the outstanding debt securities of the affected series, voting separately, or of all series, voting together as one class, depending on the nature of the proceeding, may direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee. However, unless the indenture requires otherwise, the trustee is not under any obligation to exercise any of its rights or powers under the indenture at the request or direction of holders of debt securities unless such holders offer reasonable indemnity to the trustee.

 

Defeasance and Covenant Defeasance

 

We may, at our option, irrevocably deposit with the trustee money and/or United States government obligations in an amount that would be sufficient to pay the principal of and premium, if any, and interest on the debt securities of a series when each payment becomes due. If we do so, we may then elect to take advantage of the concept of defeasance, which allows us to be discharged from our obligations on the debt securities of such series, other than certain continuing obligations specified in the indenture relating to:

 

  ž the transfer of debt securities;

 

  ž the replacement of temporary or mutilated, lost or stolen debt securities; and

 

  ž the place we maintain for payments of the debt securities.

 

Alternately, we may elect to take advantage of the concept of covenant defeasance, which allows us to be discharged from our obligations with respect to the debt securities of such series under certain covenants.

 

Notwithstanding the deposit of funds and/or United States government obligations described above, in order to effect defeasance or covenant defeasance, the indenture requires us to deliver to the trustee an opinion of counsel that the contemplated defeasance or covenant defeasance will not cause the holders of debt securities of the relevant series to recognize income, gain or loss for federal income tax purposes.

 

Modification and Waiver

 

Under the indenture, Ambac and the trustee may supplement the indenture for certain purposes which would not materially adversely affect the interests of the holders of debt securities of a series without the consent of those holders. Ambac and the trustee may also modify the indenture or any supplemental indenture in a manner that affects the interests or rights of the holders of debt securities with the consent of the holders of at least a majority in principal amount of the outstanding debt securities of all affected series, voting together as one class. However, any modification which would

 

  (a) change the maturity or reduce the principal amount of any debt securities, reduce their interest rate or extend the time of interest payments, reduce any amount payable upon redemption of any debt securities or impair or affect the right of any holder of debt securities to institute suit for payments on the debt securities or

Table of Contents

 

  (b) make certain changes to the requirements for modification of the indenture or any supplemental indenture, requires the consent of each holder of debt securities that would be affected by the modification.

 

The indenture permits the holders of a majority in aggregate principal amount of the outstanding debt securities of all series, voting together as one class, to waive our compliance with certain covenants contained in the indenture.

 

Payment and Paying Agents

 

We will make payment of principal of and premium, if any, and interest on debt securities at the place we designate. We may, at our option, make payments of interest by check mailed to the address of the person entitled to receive such interest payment according to the register for the debt securities or by transfer to an account of such person. Interest payments will be made to the person in whose name a debt security is registered as of a certain number of days prior to the relevant payment date. Although we may designate additional paying agents or remove paying agents, we will at all times maintain a paying agent in each place we designate for payment.

 

If the debt securities are represented by global certificates, payments will be made to The Depository Trust Company.

 

Denominations, Registrations and Transfer

 

Unless we tell you otherwise in an accompanying prospectus supplement, debt securities will be represented by one or more global certificates registered in the name of a nominee for The Depository Trust Company. In such case, each owner’s beneficial interest in the global securities will be shown on the records of DTC and transfers of beneficial interests will only be effected through DTC’s records.

 

Beneficial interests in a global security may only be exchanged for certificated securities registered in the particular owner’s name if:

 

  ž DTC notifies us that it is unwilling or unable to continue serving as the depositary for the relevant global securities or DTC ceases to maintain certain qualifications under the Securities Exchange Act of 1934 and no successor depositary has been appointed for 90 days;

 

  ž We determine, in our sole discretion, that the global security shall be exchangeable; or

 

  ž an Event of Default has occurred and is continuing.

 

If debt securities are issued in certificated form, they will only be issued in the minimum denomination specified in the accompanying prospectus supplement and integral multiples of such denomination. Transfers and exchanges of such debt securities will only be permitted in such minimum denomination. Transfers of debt securities in certificated form may be registered at the trustee’s corporate office or at the offices of any paying agent or trustee appointed by Ambac under the indenture. Exchanges of debt securities for an equal aggregate principal amount of debt securities in different denominations may also be made at such locations.

 

Governing Law

 

The indenture and debt securities will be governed by the laws of New York.

Our Relationship with the Trustee

 

The trustee under the indenture, The Chase Manhattan Bank, occasionally acts as trustee in connection with obligations insured by Ambac and its subsidiaries. We also have other business dealings with The Chase Manhattan Bank and its affiliates in its capacity as a commercial bank. The Chase Manhattan Bank also is a member of a group of 17 highly rated banks that provides a $800 million seven-year irrevocable limited recourse line of credit to Ambac Assurance. Of the $800 million, The Chase Manhattan Bank has provided us with $26 million. This line of credit provides liquidity to Ambac Assurance in the event claims from municipal and certain mortgage-backed and asset-backed securities in its covered portfolios exceed specified levels. As of December 31, 2000 no amounts are outstanding.

 

Conversion or exchange rights

 

The prospectus supplement will describe the terms, if any, on which a series of debt securities may be convertible into or exchangeable for our common stock, preferred stock or other debt securities. These terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. These provisions may allow or require the number of our shares of common stock or other securities to be received by the holders of such series of debt securities to be adjusted.
