PROSPECTUS SUPPLEMENT

(To prospectus dated January 20, 2011)

$25,000,000

6.625% Senior Notes due 2023

We are offering $25,000,000 principal amount of our 6.625% Senior Notes due 2023 (the “Notes”) as described in this prospectus supplement and the accompanying prospectus. Interest on the Notes will accrue from May 1, 2013 and will be paid quarterly in arrears on February 1, May 1, August 1 and November 1 of each year, commencing on August 1, 2013. The Notes will mature on May 1, 2023. We may redeem the Notes in whole or in part on or after May 1, 2016, at our option at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest to the date of redemption, as described under “Description of Notes—Optional Redemption.” The Notes will be issued in denominations of $25 and in integral multiples thereof.

The Notes will be our general unsecured senior obligations, will rank equally with all of our existing and future senior unsecured indebtedness and will be senior to our existing and any future indebtedness expressly made subordinate to the Notes. The Notes will be effectively subordinated to all of our existing and future secured indebtedness, including all of our obligations under repurchase agreements relating to mortgage-backed securities, or MBS, we own (to the extent of the value of the assets securing such indebtedness) and structurally subordinated to all existing and future liabilities and preferred stock claims of third parties of our subsidiaries, including trade payables.

Investing in the Notes involves a high degree of risk. You should carefully consider the risks described under “Risk Factors” beginning on page S-6 of this prospectus supplement and in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus.

Neither the U.S. Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

We intend to apply to list the Notes on the New York Stock Exchange (“NYSE”). If approved for listing, trading on the NYSE is expected to begin within 30 days of May 1, 2013, the original issue date.

FORWARD-LOOKING STATEMENTS

When used in this prospectus supplement, in the accompanying prospectus, in future filings with the Securities and Exchange Commission, or the SEC, or in press releases or other written or oral communications, statements which are not historical in nature, including those containing words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “goal,” “objective,” “potential,” “project,” “should,” “will” and “would” or the negative of these terms or other comparable terminology, are intended to identify “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and, as such, may involve known and unknown risks, uncertainties and assumptions. The forward-looking statements we make in this prospectus supplement and the accompanying prospectus and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus include, but are not limited to, statements about the following:

• our ability to forecast our tax attributes, which are based upon various facts and assumptions, and our ability to protect and use our net operating losses, or NOLs, and net capital losses, or NCLs, to offset future taxable income and gains, including whether our shareholder rights plan will be effective in preventing an ownership change that would significantly limit our ability to utilize such losses;

• our investment, hedging and financing strategies and the success of these strategies;

• the effect of governmental regulation and actions;

• our ability to quantify and manage risk;

• the effect of general economic conditions on our business; and

• other factors discussed under “Risk Factors” and elsewhere in this prospectus supplement.

Forward-looking statements are based on our beliefs, assumptions and expectations as to our future performance, taking into account information currently in our possession. These beliefs, assumptions and expectations may change as a result of many possible events or factors, not all of which are known to us or are within our control. If a change occurs, the performance of our portfolio and our business, financial condition, liquidity and results of operations may vary materially from those expressed, anticipated or contemplated in our forward-looking statements. You should carefully consider these risks, along with the following factors that could cause actual results to vary from our forward-looking statements, before making an investment in our securities:

• effects of regulatory proceedings, litigation and contractual claims against us, our officers and our directors;

• the overall environment for interest rates, changes in interest rates, interest rate spreads, the yield curve and prepayment rates;

• current conditions and further adverse developments in the residential mortgage market and the overall economy;

• potential risk attributable to our mortgage-related portfolios, including changes in fair value;

• our use of leverage and our dependence on repurchase agreements and other short-term borrowings to finance our mortgage-related holdings;

• the availability of certain short-term liquidity sources;

• the federal conservatorship of the Federal National Mortgage Association, or Fannie Mae, and the Federal Home Loan Mortgage Corporation, or Freddie Mac, and related efforts, along with any changes in laws and regulations affecting the relationship between Fannie Mae and Freddie Mac and the federal government;

• mortgage loan prepayment activity, modification programs and future legislative action;

• changes in our acquisition, hedging and leverage strategies, changes in our asset allocation and changes in our operational policies, all of which may be changed by us without shareholder approval;

• competition for investment opportunities, including competition from the U.S. Department of Treasury for investments in agency-backed MBS;

• failure of sovereign or municipal entities to meet their debt obligations or a downgrade in the credit rating of such debt obligations;

• fluctuating quarterly operating results;

• changes in laws and regulations and industry practices that may adversely affect our business;

• volatility of the securities markets and activity in the secondary securities markets; and

• the other important factors identified, or incorporated by reference in this prospectus supplement or the accompanying prospectus, including, but not limited to those under the captions “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Quantitative and Qualitative Disclosures about Market Risk” in our Annual Report on Form 10-K for the year ended December 31, 2012 and those described under the caption “Risk Factors” in this prospectus supplement.

We cannot guarantee future results, levels of activity, performance or achievements. All forward-looking statements speak only as of the date on which they are made.

SUMMARY

The following summary is qualified in its entirety by the more detailed information included elsewhere or incorporated by reference into this prospectus supplement and the accompanying prospectus. Because this is a summary, it may not contain all of the information that is important to you. You should read the entire prospectus supplement and the accompanying prospectus, including the section entitled “Risk Factors” and the documents incorporated by reference herein before making an investment decision.

Our Company

Arlington Asset Investment Corp. is a principal investment firm that acquires and holds mortgage-related and other assets. We acquire MBS, either issued by U.S. government agencies or guaranteed as to principal and interest by U.S. government agencies or U.S. government-sponsored entities, or agency-backed MBS. We also acquire MBS issued by private organizations, or private-label MBS, subject to maintaining our exemption from regulation as an investment company under the 1940 Act.

We are a Virginia corporation and taxed as a C corporation for U.S. federal tax purposes. We are subject to corporate income tax on our taxable income and gains. Even though we are able to use NOL and NCL carry-forwards against our taxable income and capital gains, we still have some tax liability that is attributable to federal alternative minimum tax and state and local taxes on our taxable income and gains that are not offset by our NOL and NCL carry-forwards. At December 31, 2012, we had $230.3 million of NOL carry-forwards and $285.3 million of NCL carry-forwards. On December 31, 2012, $92.7 million of our NCL carry-forwards expired. Our NCL carry-forwards are available to offset taxable capital gains through 2014, and our NOL carry-forwards will begin to expire in 2027.

We revoked our status as a real estate investment trust, or REIT, effective as of January 1, 2009. Revoking our REIT status freed us from having to satisfy the income, asset, distribution and stock ownership requirements applicable to REITs, which provides us with more flexibility in executing our business strategy. Specifically, because we are no longer required to derive a significant portion of our income from mortgage or other real estate related acquisitions, we have greater flexibility to acquire other types of assets as part of our principal acquisition activity, subject to maintaining compliance with our exclusion from regulation as an investment company under the 1940 Act. In addition, because we are no longer subject to the REIT distribution requirement, we have greater flexibility to retain our earnings to fund future growth. Although we currently have no intention to re-elect REIT status, we will be eligible to make this election beginning with our 2014 taxable year.

Our principal executive offices are located at Potomac Tower, 1001 Nineteenth Street North, Arlington, Virginia, 22209, and our telephone number is (703) 373-0200. Our website is www.arlingtonasset.com. The information on our website is not, and should not be interpreted to be, part of this prospectus supplement or the accompanying prospectus.

Legal Proceedings

As previously disclosed, on August 19, 2011, Hildene Capital Management, LLC filed a purported class action complaint captioned Hildene Capital Management, LLC v. Friedman, Billings, Ramsey Group, Inc. (d/b/a Arlington Asset Investment Corp.), FBR Capital Trust VI, FBR Capital Trust X, Wells Fargo Bank, N.A., as Trustee, and John and Jane Does 1 through 100, No. 11 Civ. 5832, in the United States District Court for the Southern District of New York. On March 22, 2013, the Plaintiffs filed a Stipulation of Voluntary Dismissal, dismissing the case with prejudice.

Recent Developments

Management has made preliminary estimates of our net income per diluted share for the quarter ended March 31, 2013 and our book value per share as of March 31, 2013. The preliminary estimates are subject to revision as we prepare our interim financial statements, including all disclosures required by accounting principles generally accepted in the United States, or GAAP, as of and for the quarter ended March 31, 2013. Factors that could cause final financial results to differ from the preliminary estimates include, but are not limited to: (i) additional adjustments in the calculation of financial results for, or book value as of, the quarter end date, (ii) discovery of new information that alters expectations about first quarter 2013 results or impacts valuation methodologies underlying these results, (iii) errors in the assessment of portfolio value, and (iv) accounting changes required by GAAP.

We estimate that, when finally determined, for the quarter ended March 31, 2013 GAAP net income will be in the range of $0.21 to $0.25 per share. This reflects the release of deferred tax asset reserves of approximately $12.22 per share in the fourth quarter of 2012 and changes in the marked-to-market losses in agency-backed MBS and related hedge positions during the quarter ended March 31, 2013. We further estimate that, when finally determined, book value per share as of March 31, 2013 will be in the range of $31.00 to $34.00. The book value per share estimate gives effect to the $0.875 per share quarterly dividend described below.

The preliminary financial data included in this prospectus supplement has been prepared by, and is the responsibility of, our management. PricewaterhouseCoopers LLP has not audited, reviewed, compiled or performed any procedures with respect to the accompanying preliminary financial data. Accordingly, PricewaterhouseCoopers LLP does not express an opinion or any other form of assurance with respect thereto.

On March 13, 2013, we completed a public offering of 3,450,000 shares of Class A common stock, including 450,000 shares of Class A common stock purchased by the underwriters pursuant to an option to purchase additional shares, for net proceeds of approximately $87.0 million after deducting underwriting discounts and commissions and estimated expenses. The net proceeds of the offering were invested in 30 year fixed-rate agency-backed MBS and private-label MBS. As of March 31, 2013, our MBS portfolio consisted of approximately $1.9 billion in fair value.

On March 15, 2013, our board of directors authorized and we declared a dividend of $0.875 per share of Class A common stock for the first quarter of 2013. The dividend is scheduled to be paid on April 30, 2013 to shareholders of record as of the close of business on March 28, 2013.

S-5

RISK FACTORS

An investment in the Notes involves significant risks, including the risks described below. Before you decide to invest in the Notes, you should consider the risk factors below relating to the offering as well as the risk factors described in our Annual Report on Form 10-K for the year ended December 31, 2012, which is incorporated by reference into this prospectus supplement. Such risks are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially adversely affect us. The risks described could affect our business, financial condition or results of operations. In such a case, you may lose all or part of your original investment.

Risks Related to Recent Developments

There are material limitations in estimating our results for prior periods before the completion of our and our auditors’ customary review procedures for such period.

The preliminary estimated results set forth in this prospectus supplement under the heading “Recent Developments” are not a comprehensive statement of our financial results for our first fiscal quarter of 2013 and have not been reviewed or audited by our independent registered public accounting firm. Our consolidated financial statements for the first fiscal quarter of 2013 will not be available until after this offering is completed, and, consequently, will not be available to you prior to investing in this offering. The final financial results for the first fiscal quarter of 2013 may vary from our expectations and may be materially different from the preliminary financial estimates we have provided due to completion of quarterly closing procedures, reviewing adjustments and other developments that may arise between now and the time the financial results for the quarter are finalized. Accordingly, investors should not place undue reliance on such financial information.

Risks Related to this Offering

Our high level of indebtedness may harm our financial condition and results of operations.

As of December 31, 2012, we had approximately $1.5 billion of secured indebtedness, including obligations under repurchase agreements relating to MBS, and no outstanding preferred stock held by third parties. Our level of indebtedness could have important consequences to you, because:

• it could affect our ability to satisfy our financial obligations, including those relating to the Notes;

• a substantial portion of our cash flows from operations will have to be dedicated to interest and principal payments and may not be available for operations, capital expenditures, expansion, acquisitions or general corporate or other purposes;

• it may impair our ability to obtain additional debt or equity financing in the future;

• it may limit our ability to refinance all or a portion of our indebtedness on or before maturity;

• it may limit our flexibility in planning for, or reacting to, changes in our business and industry; and

• it may make us more vulnerable to downturns in our business, our industry or the economy in general.

Our operations may not generate sufficient cash to enable us to service our debt. If we fail to make a payment on the Notes, we could be in default on the Notes, and this default could cause us to be in default on our other outstanding indebtedness. Conversely, a default under any of our other indebtedness (including our $15 million in long-term debentures described under “Description of Other Indebtedness”), if not waived, could result in acceleration of the debt outstanding under the related agreement and entitle the holders thereof to bring suit for the enforcement thereof or exercise other remedies provided thereunder. In addition, such default or acceleration may result in an event of default and acceleration of other indebtedness of the Company, entitling the holders thereof to bring suit for the enforcement thereof or exercise other remedies provided thereunder. If a judgment is obtained by any such holders, such holders could seek to collect on such judgment from the assets of the Company. However, no event of default under the Notes would result from such default or acceleration or such suit, other exercise of remedies or collection proceeding. If that should occur, we may not be able to pay all such debt or to borrow sufficient funds to refinance it. Even if new financing were then available, it may not be on terms that are acceptable to us. The indenture governing the Notes will not restrict our ability to incur additional indebtedness.

S-6

Despite current indebtedness levels, we may still be able to incur substantially more debt. This could exacerbate the risks described above.

We may be able to incur substantial additional indebtedness in the future. The terms of the indenture governing the Notes will not prohibit us from doing so. If we incur any additional indebtedness that ranks pari passu with the notes, the holders of that debt will be entitled to share ratably with you in any proceeds distributed in connection with any insolvency, liquidation, reorganization or dissolution. This may have the effect of reducing the amount of proceeds paid to you. If new debt is added to our current debt levels, the related risks that we now face could intensify.

Incurrence of additional debt would also further reduce the cash available to invest in operations, as a result of increased debt service obligations. The more leveraged we become, the more we, and in turn the holders of our securities, become exposed to the risks described in the risk factor entitled “Increased leverage as a result of this offering may harm our financial condition and results of operations.”

The effective subordination of the Notes may limit our ability to satisfy our obligations under the Notes.

The Notes will be our senior unsecured obligations. The Notes will rank equally with all of our indebtedness that is not expressly subordinated to the Notes. The Notes will be effectively subordinated to all of our secured indebtedness, which includes, but is not limited to, our repurchase agreements, interest rate swaps, and other financing arrangements, to the extent of the value of the collateral securing such indebtedness. As of December 31, 2012, our total consolidated indebtedness related to interest-bearing liabilities was approximately $1.6 billion. As of December 31, 2012, we had outstanding approximately $1.5 billion of repurchase agreements with weighted average remaining maturities of 14.5 days, with agency-backed MBS and private label MBS with an estimated fair value of approximately $1.6 billion pledged as collateral on our outstanding repurchase agreements. The indenture governing the Notes does not prohibit us or our subsidiaries from incurring additional secured indebtedness in the future. Consequently, in the event of an event of default under our secured indebtedness or a bankruptcy, liquidation, dissolution, reorganization or similar proceeding with respect to us, the holders of any secured indebtedness will be entitled to proceed directly against the collateral that secures such secured indebtedness. Therefore, such collateral will not be available for satisfaction of any amounts owed under our unsecured indebtedness, including the Notes, until such secured indebtedness is satisfied in full.

The Notes also will be effectively subordinated to all liabilities and preferred equity of all of our subsidiaries. In the event of a bankruptcy, liquidation, dissolution, reorganization or similar proceeding with respect to any such subsidiary, we are an equity owner of such subsidiary, and therefore holders of our debt, including the Notes, will be subject to the prior claims of such subsidiary’s creditors, including trade creditors, and preferred equity holders. As of December 31, 2012, we had approximately $1.5 billion of secured indebtedness, including obligations under repurchase agreements relating to MBS, and no outstanding preferred stock held by third parties. The indenture governing the Notes does not prohibit us or our subsidiaries from incurring additional indebtedness or issuing preferred equity in the future. In addition, future debt and security agreements entered into by our subsidiaries may contain various restrictions, including restrictions on payments by our subsidiaries to us and the transfer by our subsidiaries of assets pledged as collateral.

The indenture under which the Notes will be issued contains limited protection for holders of the Notes.

The indenture under which the Notes will be issued offers limited protection to holders of the Notes. The terms of the indenture and the Notes do not restrict our or any of our subsidiaries’ ability to engage in, or otherwise be a party to, a variety of corporate transactions, circumstances or events that could have an adverse impact on your investment in the Notes. In particular, the terms of the indenture and the Notes will not place any restrictions on our or our subsidiaries’ ability to:

• issue securities or otherwise incur additional indebtedness or other obligations, including (1) any indebtedness or other obligations that would be equal in right of payment to the Notes, (2) any

S-7

indebtedness or other obligations that would be secured and therefore rank effectively senior in right of payment to the Notes to the extent of the values of the assets securing such debt, (3) indebtedness of ours that is guaranteed by one or more of our subsidiaries and which therefore is structurally senior to the Notes and (4) securities, indebtedness or obligations issued or incurred by our subsidiaries that would be senior to our equity interests in our subsidiaries and therefore rank structurally senior to the Notes with respect to the assets of our subsidiaries;

• pay dividends on, or purchase or redeem or make any payments in respect of, capital stock or other securities ranking junior in right of payment to the Notes;

• sell assets (other than certain limited restrictions on our ability to consolidate, merge or sell all or substantially all of our assets);

• enter into transactions with affiliates;

• create liens (including liens on the shares of our subsidiaries) or enter into sale and leaseback transactions;

• make investments; or

• create restrictions on the payment of dividends or other amounts to us from our subsidiaries.

In addition, the indenture does not include any protection against certain events, such as a change of control, a leveraged recapitalization or “going private” transaction (which may result in a significant increase of our indebtedness levels), restructuring or similar transactions. Furthermore, the terms of the indenture and the Notes do not protect holders of the Notes in the event that we experience changes (including significant adverse changes) in our financial condition, results of operations or credit ratings, as they do not require that we or our subsidiaries adhere to any financial tests or ratios or specified levels of net worth, revenues, income, cash flow, or liquidity.

Our ability to recapitalize, incur additional debt and take a number of other actions that are not limited by the terms of the Notes may have important consequences for you as a holder of the Notes, including making it more difficult for us to satisfy our obligations with respect to the Notes or negatively affecting the trading value of the Notes.

Other debt we issue or incur in the future could contain more protections for its holders than the indenture and the Notes, including additional covenants and events of default. The issuance or incurrence of any such debt with incremental protections could affect the market for and trading levels and prices of the Notes.

An increase in market interest rates could result in a decrease in the value of the Notes.

In general, as market interest rates rise, notes bearing interest at a fixed rate decline in value. Consequently, if you purchase the Notes, and the market interest rates subsequently increase, the market value of your Notes may decline. We cannot predict the future level of market interest rates.

An active trading market for the Notes may not develop, which could limit the market price of the Notes or your ability to sell them.

The Notes are a new issue of debt securities for which there currently is no trading market. We intend to apply to list the Notes on the NYSE within 30 days of the original issue date under the symbol “AIW.” We cannot provide any assurances that an active trading market will develop for the Notes or that you will be able to sell your Notes. If the Notes are traded after their initial issuance, they may trade at a discount from their initial offering price depending on prevailing interest rates, the market for similar securities, our credit ratings, general economic conditions, our financial condition, performance and prospects and other factors. The underwriters have advised us that they may make a market in the Notes, but they are not obligated to do so. The underwriters may discontinue any market-making in the Notes at any time at their sole discretion. Accordingly, we cannot assure you that a liquid trading market will develop for the Notes, that you will be able to sell your Notes at a particular time or that the price you receive when you sell will be favorable. To the extent an active trading market does not develop, the liquidity and trading price for the Notes may be harmed. Accordingly, you may be required to bear the financial risk of an investment in the Notes for an indefinite period of time.

S-8

We may issue additional Notes.

Under the terms of the indenture governing the Notes, we may from time to time without notice to, or the consent of, the holders of the Notes, create and issue additional notes which will be equal in rank to the Notes.

The Notes will not be rated and we do not intend to seek a rating for the Notes.

We do not intend to have the Notes rated by any rating agency. Unrated securities usually trade at a discount to similar rated securities. As a result, there is a risk that the Notes may trade at a price that is lower than they might otherwise trade if rated by a rating agency. It is possible, however, that one or more rating agencies might independently determine to assign a rating to the Notes. In addition, we may elect to issue other securities for which we may seek to obtain a rating. If any ratings are assigned to the Notes in the future or if we issue other securities with a rating, such ratings, if they are lower than market expectations or are subsequently lowered or withdrawn, could adversely affect the market for or the market value of the Notes.

S-9

USE OF PROCEEDS

Assuming we sell an aggregate principal amount of $25,000,000 of Notes in this offering, we estimate that the net proceeds we will receive from the sale of Notes in this offering will be approximately $24.0 million after deducting underwriting commissions of approximately $787,500, and estimated offering expenses of approximately $175,000 payable by us.

We expect to use the net proceeds of this offering to acquire certain of our target assets, including agency-backed MBS and private label MBS. We expect then to borrow against the assets that we acquire with the net proceeds of this offering through repurchase agreements and to use the proceeds of the borrowings to acquire additional target assets. We may also use the net proceeds for general working capital purposes.

Pending these uses, we intend to maintain the net proceeds in interest-bearing, short-term, marketable investment grade securities or money market accounts or (interest or non-interest bearing) checking (or escrow) accounts. These investments may include, for example, government securities other than agency securities, certificates of deposit and interest-bearing bank deposits. We expect these investments to provide a lower net return than we will seek to achieve from our target assets.

DESCRIPTION OF NOTES

The Notes will be issued under an indenture dated as of May 1, 2013, between us and Wells Fargo Bank, National Association, as trustee, as supplemented by a supplemental indenture dated as of May 1, 2013, setting forth the terms and conditions of the Notes. We refer to the indenture, as supplemented by the supplemental indenture, as the indenture and to Wells Fargo Bank, National Association as the Trustee.

Because this section is a summary, it does not describe every aspect of the Notes and the indenture. We urge you to read the indenture because it, and not this description, defines your rights as a holder of the Notes.

General

The Notes will mature on May 1, 2023. The principal payable at maturity will be 100.0% of the aggregate principal amount. The interest rate of the Notes is 6.625% per year and will be paid every February 1, May 1, August 1 and November 1 of each year, commencing on August 1, 2013, and the regular record dates for interest payments will be the 15th calendar day before each interest payment date. The initial interest period will be the period from and including May 1, 2013 to, but excluding, the initial interest payment date, and the subsequent interest periods will be the periods from and including an interest payment date to, but excluding, the next interest payment date or the stated maturity date, as the case may be.

We will issue the Notes in denominations of $25 and integral multiples of $25 in excess thereof. The Notes will not be subject to any sinking fund and holders of the Notes will not have the option to have the Notes repaid prior to the stated maturity date.

The indenture does not contain any provisions that give you protection in the event we issue a large amount of debt or we are acquired by another entity or we pay a large dividend to our shareholders.

We have the ability to issue indenture securities with terms different from the Notes and, without the consent of the holders thereof, to reopen the Notes and issue additional Notes in any amount having the same terms as the Notes in all respects, except for the issue date, the issue price, and the initial interest payment date and rights. Any such additional Notes will constitute “Notes” for all purposes of the indenture and will (together with all other Notes issued under the indenture) constitute a single series of Notes under the indenture. If additional Notes are not fungible with the Notes offered hereby for U.S. federal income tax purposes, as applicable, as determined by us, such additional Notes may have a separate CUSIP number.

Optional Redemption

The Notes may be redeemed in whole or in part at any time or from time to time at our option on or after May 1, 2016 upon not less than 30 days nor more than 60 days written notice by mail prior to the date fixed for redemption thereof, at a redemption price equal to 100% of the outstanding principal amount thereof plus accrued and unpaid interest payments otherwise payable for the then-current quarterly interest period accrued to the date fixed for redemption.

You may be prevented from exchanging or transferring the Notes when they are subject to redemption. In case any Notes are to be redeemed in part only, the redemption notice will provide that, upon surrender of such Note, you will receive, without a charge, a new Note or Notes of authorized denominations representing the principal amount of your remaining unredeemed Notes. Any exercise of our option to redeem the Notes will be done in compliance with the indenture.

If we redeem only some of the Notes, the Trustee will determine the method for selection of the particular Notes to be redeemed in accordance with the indenture and in accordance with the rules of any national securities exchange or quotation system on which the Notes are listed. Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the Notes called for redemption.

S-13

Payment and Paying Agents

We will pay interest to the person listed in the Trustee’s records as the owner of the Notes at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the Notes on the interest due date. That day, usually about two weeks in advance of the interest due date, is called the “record date.” Because we will pay all the interest for an interest period to the holders on the record date, holders buying and selling the Notes must work out between themselves the appropriate purchase price. The most common manner is to adjust the sales price of the Notes to prorate interest fairly between buyer and seller based on their respective ownership periods within the particular interest period. This prorated interest amount is called “accrued interest”.

Payments on Global Securities

We will make payments on a global security in accordance with the applicable policies of the depositary as in effect from time to time. Under those policies, we will make payments directly to the depositary, or its nominee, and not to any indirect holders who own beneficial interests in the global security. An indirect holder’s right to those payments will be governed by the rules and practices of the depositary and its participants.

Payment When Offices Are Closed

If any payment is due on the Notes on a day that is not a business day, we will make the payment on the next day that is a business day. Payments made on the next business day in this situation will be treated under the indenture as if they were made on the original due date. Such payment will not result in a default under the Notes or the indenture, and no interest will accrue on the payment amount from the original due date to the next day that is a business day.

Holders should consult their banks or brokers for information on how they will receive payments on the Notes.

Events of Default

You will have rights if an Event of Default occurs with respect to the Notes and the Event of Default is not cured, as described later in this subsection.

The term “Event of Default” with respect to the Notes means any of the following:

• We do not pay the principal of any Note on its due date.

• We do not pay interest on any Note when due, and such default is not cured within 30 days.

• We remain in breach of any other covenant with respect to the Notes for 60 days after we receive a written notice of default stating we are in breach. The notice must be sent by either the Trustee or holders of at least 25% of the principal amount of the Notes.

• Certain events involving our bankruptcy, insolvency or reorganization.

An Event of Default for a particular series of debt securities does not necessarily constitute an Event of Default for any other series of debt securities issued under the same or any other indenture. The Trustee may withhold notice to the holders of the Notes of any default, except in the payment of principal, premium or interest, if it considers the withholding of notice to be in the best interests of the holders.

Remedies if an Event of Default Occurs

If an Event of Default has occurred and has not been cured, the Trustee or the holders of at least 25% in principal amount of the Notes may declare the entire principal amount of all the Notes to be due and immediately payable. In the case of an Event of Default involving our bankruptcy, insolvency or reorganization with respect

S-14

to us, the principal of, and accrued and unpaid interest on, all notes will automatically become immediately due and payable. This is called a declaration of acceleration of maturity. In certain circumstances, a declaration of acceleration of maturity may be canceled by the holders of a majority in principal amount of the Notes.

The Trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the Trustee protection satisfactory to it from expenses and liability (called an “indemnity”). If indemnity satisfactory to the Trustee is provided, the holders of a majority in principal amount of the Notes may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the Trustee. The Trustee may refuse to follow those directions in certain circumstances. No delay or omission in exercising any right or remedy will be treated as a waiver of that right, remedy or any Event of Default.

Before you are allowed to bypass the Trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the Notes, the following must occur:

• You must give the Trustee written notice that an Event of Default has occurred with respect to the Notes and remains uncured.

• The holders of at least 25% in principal amount of all the Notes must make a written request that the Trustee take action because of the default and must offer indemnity to the Trustee against the cost and other liabilities of taking that action.

• The Trustee must not have taken action for 60 days after receipt of the above notice and offer of indemnity.

• The holders of a majority in principal amount of the Notes must not have given the Trustee a direction inconsistent with the above notice during that 60 day period.

However, you are entitled at any time to bring a lawsuit for the payment of money due on your notes on or after the due date of that payment.

Holders of a majority in principal amount of the Notes may waive any past defaults other than a default:

• in the payment of principal, any premium or interest; or

• in respect of any provision of the Notes or the indenture that cannot be modified or amended without the consent of each holder of the Notes.

Holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the Trustee and how to declare or cancel an acceleration of maturity.

Each year, we will furnish to the Trustee a written statement of certain of our officers certifying that to their knowledge we are in compliance with the indenture and the Notes, or else specifying any default.

Merger or Consolidation

Under the terms of the indenture, we are generally permitted to consolidate or merge with another entity. We are also permitted to sell all or substantially all of our assets to another entity. However, we may not take any of these actions unless all the following conditions are met:

• Where we merge out of existence or sell our assets, the resulting entity must agree to be legally responsible for our obligations under the Notes and the indenture.

• The merger or sale of assets must not cause a default on the Notes and we must not already be in default (unless the merger or sale would cure the default). For purposes of this no-default test, a default

S-15

would include an Event of Default that has occurred and has not been cured, as described under “Events of Default” above. A default for this purpose would also include any event that would be an Event of Default if the requirements for giving us notice of default or our default having to exist for a specified period of time were disregarded.

• We must deliver certain certificates and documents to the Trustee.

Modification or Waiver

There are three types of changes we can make to the indenture and the Notes issued thereunder.

Changes Requiring Your Approval

First, there are changes that we cannot make to the Notes without approval from each affected holder. The following is a list of those types of changes:

• change the stated maturity of the principal of or interest on the Notes;

• reduce any amounts due on the Notes;

• reduce the amount of principal payable upon acceleration of the maturity of a security following a default;

• change the place or currency of payment on the Notes or the redemption provisions applicable to the Notes;

• impair your right to institute suit for the enforcement of any payment of principal of or interest on the Notes;

• reduce the percentage of holders of Notes whose consent is needed to modify or amend the indenture or the Notes;

• reduce the percentage of holders of Notes whose consent is needed to waive compliance with certain provisions of the indenture or the Notes or to waive certain defaults; and

• modify any other material aspect of the provisions of the indenture or the Notes dealing with supplemental indentures, modification and waiver of past defaults, changes to the quorum or voting requirements or the waiver of certain covenants.

Changes Not Requiring Approval

The second type of change does not require any vote by the holders of the Notes. This type is limited to clarifications and certain other changes that would not adversely affect holders of the Notes in any material respect.

Changes Requiring Majority Approval

Any other change to the indenture and the Notes would require the following approval:

• If the change affects only the Notes, it must be approved by the holders of a majority in principal amount of the Notes (including any additional Notes).

• If the change affects more than one series of debt securities issued under the same indenture, it must be approved by the holders of a majority in principal amount of all of the series affected by the change, with all affected series voting together as one class for this purpose.

S-16

The holders of a majority in principal amount of a series of debt securities issued under the indenture may waive our compliance with some of our covenants applicable to that series. However, we cannot obtain a waiver of a payment default or of any of the matters covered by the bullet points included above under “—Changes Requiring Your Approval”.

Further Details Concerning Voting

When taking a vote, we will use the principal amount that would be due and payable on the voting date if the maturity of the Notes were accelerated to that date because of a default, to decide how much principal to attribute to the Notes.

The Notes will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust money for their payment or redemption. The Notes will also not be eligible to vote if they have been fully defeased as described later under “Defeasance—Full Defeasance”.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of the Notes that are entitled to vote or take other action under the indenture. If we set a record date for a vote or other action to be taken by holders of the Notes, that vote or action may be taken only by persons who are holders of the Notes on the record date and must be taken within eleven months following the record date.

Holders should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indenture or the Notes or request a waiver.

Defeasance

The following provisions will be applicable to the Notes.

Covenant Defeasance

Under applicable law, we can make the deposit described below and be released from some of the restrictive covenants and Events of Default in the indenture under which the Notes were issued. This is called “covenant defeasance.” In that event, you would lose the protection of those restrictive covenants and Events of Default but would gain the protection of having money and government securities set aside in trust to repay your Notes. In order to achieve covenant defeasance, the following conditions must be satisfied:

• Since the Notes are denominated in U.S. dollars, we must deposit in trust for the benefit of all holders of the Notes a combination of money and U.S. government or U.S. government agency notes or bonds that in the opinion of a nationally recognized firm of independent public accountants will generate enough cash to make interest, principal and any other payments on the Notes on their due dates.

• We must deliver to the Trustee a legal opinion of our counsel confirming that, under current U.S. federal income tax law, we may make the above deposit without causing you to be taxed on the Notes any differently than if we did not make the deposit and just repaid the Notes ourselves at maturity.

• Defeasance must not result in a breach or violation of, or result in a default under, the indenture or any of our other material agreements or instruments.

• No default or event of default, or event which with notice or lapse of time would become an event of default, with respect to the Notes shall have occurred and be continuing and no defaults or events of default related to bankruptcy, insolvency or reorganization shall occur during the next 90 days.

• We must deliver to the Trustee a legal opinion of our counsel stating that the above deposit does not require registration by us under the 1940 Act and a legal opinion and officers’ certificate stating that all conditions precedent to covenant defeasance have been complied with.

S-17

• If the notes are to be redeemed before their maturity, notice of redemption must have been given.

If we accomplish covenant defeasance, you can still look to us for repayment of the Notes if there were a shortfall in the trust deposit or the Trustee is prevented from making payment.

Full Defeasance

If there is a change in U.S. federal tax law, as described below, we can legally release ourselves from all payment and other obligations on the Notes of a particular series (called “full defeasance”) if the following conditions are satisfied in order for you to be repaid:

• Since the Notes are in U.S. dollars, we must deposit in trust for the benefit of all holders of the Notes a combination of money and U.S. government or U.S. government agency notes or bonds that in the opinion of a nationally recognized firm of independent public accountants will generate enough cash to make interest, principal and any other payments on the Notes on their various due dates.

• We must deliver to the Trustee a legal opinion confirming that there has been a change in current U.S. federal tax law or an Internal Revenue Service (“IRS”) ruling that allows us to make the above deposit without causing you to be taxed on the Notes any differently than if we did not make the deposit and just repaid the Notes ourselves at maturity. Under current U.S. federal tax law, the deposit and our legal release from the Notes would be treated as though we paid you your share of the cash and notes or bonds at the time the cash and notes or bonds were deposited in trust in exchange for the Notes and you would recognize gain or loss on the Notes at the time of the deposit.

• Defeasance must not result in a breach or violation of, or constitute a default under, the indenture or any of our other material agreements or instruments.

• No default or event of default, or event which with notice or lapse of time would become an event of default, with respect to the Notes shall have occurred and be continuing and no defaults or events of default related to bankruptcy, insolvency or reorganization shall occur during the next 90 days.

• We must deliver to the Trustee a legal opinion of our counsel stating that the above deposit does not require registration by us under the 1940 Act and a legal opinion and officers’ certificate stating that all conditions precedent to defeasance have been complied with.

• If the notes are to be redeemed before their maturity, notice of redemption must have been given.

If we ever did accomplish full defeasance, as described above, you would have to rely solely on the trust deposit for repayment of the Notes. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent.

Other Covenants

In addition to any other covenants described in this prospectus supplement or the accompanying prospectus, we have also agreed that if, at any time, we are not subject to the reporting requirements of Sections 13 or 15(d) of the Exchange Act to file any periodic reports with the SEC, we agree to file with the SEC, to the extent permitted under the Exchange Act, the annual reports, quarterly reports and other documents which we would have been required to file with the SEC if we were so subject, on or before the filings dates which we would have been required file such documents if we were so subject.

Resignation of Trustee

The Trustee may resign or be removed with respect to the Notes provided that a successor trustee is appointed to act with respect to the Notes. In the event that two or more persons are acting as trustee with respect to different series of indenture securities under the indenture, each of the trustees will be a trustee of a trust separate and apart from the trust administered by any other trustee.

S-18

Indenture Provisions—Subordination and Senior Indebtedness

The Notes will be our direct unsecured obligations and will rank:

• pari passu with our future senior unsecured indebtedness;

• senior to our existing long-term debentures and any of our future indebtedness that expressly provides it is subordinated to the Notes; and

• effectively subordinated to all of our existing and future secured indebtedness (including indebtedness that is initially unsecured to which we subsequently grant security), to the extent of the value of the assets securing such indebtedness, including our borrowings under repurchase agreements; and

• structurally subordinated to all existing and future indebtedness and other obligations of any of our subsidiaries.

Listing

We intend to apply to list the Notes on the NYSE under the symbol “AIW”. If approved for listing, we expect trading in the Notes to begin within 30 days after the original issue date of the Notes. The Notes have been assigned, and will initially trade under, CUSIP number 041356 304.

Trading Characteristics

We expect the Notes to trade “flat,” meaning that purchasers will not pay, and sellers will not receive, any accrued and unpaid interest on the Notes that is not included in the trading price. Any portion of the trading price of a Note that is attributable to accrued and unpaid interest will be treated as ordinary interest income for U.S. federal income tax purposes and will not be treated as part of the amount realized for purposes of determining gain or loss on the disposition of the Note.

Sinking Fund

The Notes are not entitled to any sinking fund payments.

Book-Entry Procedures

The Notes will be represented by global securities that will be deposited and registered in the name of DTC or its nominee. This means that, except in limited circumstances, you will not receive certificates for the Notes. Beneficial interests in the Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the Notes through either DTC, if they are a participant, or indirectly through organizations that are participants in DTC.

The Notes will be issued as fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered certificate will be issued for the Notes, in the aggregate principal amount of such issue, and will be deposited with DTC. Interests in the Notes will trade in DTC’s Same Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. None of the Company, the Trustee or the Paying Agent will have any responsibility or liability for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations. Beneficial interests in any of the Notes will be shown on, and transfers will be effected only through, records maintained by DTC or its nominee and any such interest may not be exchanged for certificated securities, except in limited circumstances. Investors may elect to hold interests in a global note through either DTC (in the United States) or Clearstream Banking, société anonyme, or Euroclear Bank S.A./N.V., as operator of the Euroclear System (in Europe). Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their U.S. depositaries], which in turn will hold such interests in customers’ securities accounts in the U.S. depositaries’ names on the books of DTC.

S-19

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, 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 Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity, corporate and municipal debt issues, and money market instruments from over 100 countries that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”).

DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has Standard & Poor’s Ratings Services’ highest rating: AAA. The DTC Rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com and www.dtc.org.

Purchases of the Notes under the DTC system must be made by or through Direct Participants, which will receive a credit for the Notes on DTC’s records. The ownership interest of each actual purchaser of each security, or the “Beneficial Owner,” is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in the Notes, except in the event that use of the book-entry system for the Notes is discontinued.

To facilitate subsequent transfers, all Notes deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of the Notes with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Notes; DTC’s records reflect only the identity of the Direct Participants to whose accounts the Notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices shall be sent to DTC. If less than all of the Notes within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

Redemption proceeds, distributions, and interest payments on the Notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the

S-20

Trustee on the payment date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC nor its nominee, the Trustee, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and interest payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of us or the Trustee, but disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

DTC may discontinue providing its services as securities depository with respect to the Notes at any time by giving reasonable notice to us or to the Trustee. Under such circumstances, in the event that a successor securities depository is not obtained, certificates are required to be printed and delivered. We may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, certificates will be printed and delivered to DTC.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but neither we nor the trustee takes responsibility or assumes any liability for the accuracy thereof.

DESCRIPTION OF OTHER INDEBTEDNESS

Repurchase Agreements

We have entered into repurchase agreements to fund our investments in MBS. As of December 31, 2012, the amount at risk related to $482.1 million of repurchase agreements with Credit Suisse Securities (USA) LLC was $50.1 million, or 10.79% of our equity, with a weighted average maturity of 15 days. The following table provides information regarding our outstanding repurchase agreement borrowings as of the dates and periods indicated:

	December 31
	2012			2011
	(dollars in thousands)
Outstanding balance	$	1,497,191		$	647,977
Value of assets pledged as collateral
Agency-backed MBS		1,547,760			653,322
Private-label MBS		67,661			78,110
Weighted-average rate		0.52	%		0.49	%
Weighted-average term to maturity		14.5 days			13.1 days
Weighted-average outstanding balance during the year ended	$	953,152		$	559,086
Weighted-average rate during the year ended		0.46	%		0.36	%

Long-Term Debt

As of December 31, 2012, we had $15 million of outstanding long-term debentures. The long-term debentures accrue and require payments of interest quarterly at an annual rate of three-month LIBOR plus 2.25% to 3.00%. The weighted average interest rate on these long-term debentures was 3.09% as of December 31, 2012. The debentures mature between 2033 and 2035 and are currently redeemable by us, in whole or in part, without penalty.

The indenture relating to the long-term debentures contains certain covenants, including a covenant prohibiting dividends and stock repurchases under certain circumstances. Among other events, (a) any failure to pay interest and continuance of such failure for 30 days and (b) any failure to comply with such covenants, after notice and a grace period, would result in an event of default under the long-term debentures, entitling the holders thereof to accelerate the maturity of the long-term debentures.

The long-term debentures are subordinated in right of payment to “Senior Indebtedness,” including the Notes. No payments may be made on the long-term debentures during the existence of a payment default (beyond any period of grace) on Senior Indebtedness or if any Senior Indebtedness has been accelerated unless such default has been waived or such acceleration rescinded. Also, upon any payment or distribution of assets of the Company to creditors during any dissolution, winding-up, liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceeding, all amounts of Senior Indebtedness must be paid or payment must be provided for in money in accordance with its terms, before any payment is made by the Company on the long-term debentures.

S-22

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion summarizes certain material U.S. federal income tax considerations that may be relevant to the acquisition, ownership and disposition of the Notes. This discussion is a summary for general information only and does not purport to address all tax considerations that may be relevant to the purchase, ownership and disposition of the Notes. This discussion also does not address the U.S. federal income tax consequences of the ownership of Notes not held as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”), or the U.S. federal income tax consequences to investors subject to special treatment under the U.S. federal income tax laws, such as:

• dealers in securities or foreign currency;

• tax-exempt entities;

• banks;

• thrifts;

• regulated investment companies;

• REITs;

• traders in securities that have elected the mark-to-market method of accounting for their securities;

• controlled foreign corporations;

• passive foreign investment companies;

• insurance companies;

• persons that hold the Notes as part of a “straddle,” a “hedge” or a “conversion transaction”;

• persons liable for alternative minimum tax;

• expatriates;

• U.S. holders (as defined below) that have a “functional currency” other than the U.S. dollar; and

• pass-through entities (e.g., partnerships) or investors who hold the Notes through pass-through entities.

In addition, except where otherwise provided, this discussion is limited to the U.S. federal income tax consequences to initial holders that purchase the Notes for cash, at their original issue price, pursuant to the offering. It does not consider any tax consequences arising out of U.S. federal gift and estate tax law or under the tax laws of any foreign, state, local or other jurisdiction.

If a partnership, including any entity that is treated as a partnership for U.S. federal income tax purposes, is a beneficial owner of the Notes, the treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. If you are a partner in or owner of a partnership that is considering purchasing the Notes, you should consult with your tax advisor.

This discussion is based upon the Code, applicable Treasury Regulations promulgated thereunder, judicial authority and administrative interpretations as of the date hereof, all of which are subject to change, possibly with retroactive effect. We have not and will not seek any rulings or opinions from the IRS regarding the matters discussed below. There can be no assurance that the IRS will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling from the IRS or an opinion of counsel with respect to the U.S. federal income tax consequences of purchasing, owning or disposing of the Notes.

If you are considering investing in the Notes, we urge you to consult your tax advisor about the particular U.S. federal, state, local and foreign tax consequences of the purchase, ownership and disposition of the Notes, and the application of the U.S. federal income tax laws to your particular situation.

S-23

U.S. Holders

For purposes of this discussion, a “U.S. holder” is a beneficial owner of the Notes that, for U.S. federal income tax purposes, is:

• an individual citizen or resident of the United States;

• a corporation or other entity taxable as a corporation created or organized under the laws of the United States, any of its states or the District of Columbia;

• an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

• a trust if a U.S. court is able to exercise primary supervision over administration of the trust and one or more U.S. persons have authority to control all substantial decisions of the trust, or if the trust existed on April 20, 1996 and has validly elected to continue to be treated as a domestic trust.

Taxation of Interest

Interest on the Notes is generally taxable to a U.S. holder as ordinary income:

• when it accrues, if such U.S. holder uses the accrual method of accounting for U.S. federal income tax purposes; or

• when a U.S. holder receives it, if such U.S. holder uses the cash method of accounting for U.S. federal income tax purposes.

In general, if the terms of a debt instrument entitle a holder to receive payments other than fixed periodic interest that exceed the issue price of the instrument, such excess is treated under the Code as “original issue discount.” A U.S. holder generally will be required to recognize any such original issue discount as additional interest over the term of the instrument unless the original issue discount is de minimis. We expect that the Notes will not be issued with more than a de minimis amount of original issue discount.

Sale or Other Taxable Disposition of Notes

A U.S. holder will generally recognize taxable gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a Note. The amount of such U.S. holder’s gain or loss will equal the difference between the amount such U.S. holder receives for the Note (to the extent such amount does not represent accrued but unpaid interest, which will be treated ordinary interest income to the extent such U.S. holder has not previously included the accrued interest in gross income), and such U.S. holder’s adjusted tax basis in the Note. A U.S. holder’s adjusted tax basis in a Note generally will be the price such U.S. holder paid for the Note. Any such gain or loss on a taxable disposition of a Note as described above will generally constitute capital gain or loss and will be long-term capital gain or loss if a U.S. holder holds such Note for more than one year. Under current U.S. federal income tax law, net long-term capital gains of U.S. holders taxed at individual rates are eligible for taxation at preferential rates. The deductibility of capital losses against ordinary income is subject to limitations.

Medicare Tax

Certain U.S. holders who are individuals, estates or trusts will be subject to a 3.8% tax on all or a portion of their “net investment income,” which generally will include interest and gain on sale in respect of the Notes, subject to certain exceptions. Each U.S. holder is urged to consult its tax advisors regarding the applicability of the Medicare tax to its income and gains in respect of its investment in the Notes.

S-24

U.S. Holders Holding Through Foreign Accounts or Intermediaries

U.S. holders holding their Notes through foreign accounts or intermediaries should refer to “—Non-U.S. Holders—Recently enacted legislation” below.

Non-U.S. Holders

For purposes of this discussion, a “non-U.S. holder” is a beneficial owner of the Notes that is neither a U.S. holder nor a partnership or other pass-through entity for U.S. federal income tax purposes.

Payments on the Notes

Subject to the discussion below concerning backup withholding and recently enacted legislation, payments of interest on a Note to any non-U.S. holder will generally not be subject to U.S. federal withholding tax, provided that:

the non-U.S. holder is not:

• an actual or constructive owner of 10% or more of the total voting power of all our voting stock; or

• a controlled foreign corporation related (directly or indirectly) to us through stock ownership; and

we or our paying agent receives:

• from the non-U.S. holder, a properly completed Form W–8BEN (or substitute Form W–8BEN or the appropriate successor form) under penalties of perjury, which provides the non-U.S. holder’s name and address and certifies that the non-U.S. holder of the Note is a non-U.S. holder; or

• from a security clearing organization, bank or other financial institution that holds the Notes in the ordinary course of its trade or business (a “financial institution”) on behalf of the non-U.S. holder, certification under penalties of perjury that such a Form W—8BEN (or substitute Form W—8BEN or the appropriate successor form) has been received by it, or by another such financial institution, from the non-U.S. holder, and a copy of the Form W—8BEN (or substitute Form W—8BEN or the appropriate successor form) is furnished to the payor.

If a non-U.S. holder cannot satisfy the requirements described above, payments of interest will be subject to withholding of U.S. federal tax at a 30% rate (or lower applicable treaty rate) unless interest on the Notes is effectively connected with the conduct of a trade or business in the United States as described below. In order to claim a lower applicable treaty rate, a non-U.S. holder must provide to us (or our paying agent) a properly and validly completed Form W-8BEN and claim this reduction or exemption on the form. A non-U.S. Holder may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Special rules may apply to holders who hold Notes through “qualified intermediaries” within the meaning of U.S. federal income tax laws.

If interest on a Note is effectively connected with the conduct by a non-U.S. holder of a trade or business in the United States and, if the non-U.S. holder is entitled to the benefits under an applicable tax treaty, is attributable to a permanent establishment or a fixed base in the United States, then such income generally will be subject to U.S. federal income tax on a net basis at the rates applicable to U.S. persons generally (and, if realized by corporate holders, may also be subject to a 30% branch profits tax or such lower rate as may be available pursuant to an applicable income tax treaty). If interest is subject to U.S. federal income tax on a net basis in accordance with the rules described in the preceding sentence, payments of such interest will not be subject to U.S. withholding tax so long as the holder provides us or the paying agent with a properly and validly completed Form W-8ECI.

S-25

Non-U.S. holders should consult their tax advisors about any applicable income tax treaties, which may provide for an exemption from or a lower rate of withholding tax, exemption from or reduction of branch profits tax, or other rules different from those described above.

Sale or Other Taxable Disposition of Notes

Subject to the discussion below concerning backup withholding and recently enacted legislation, any gain realized by a non-U.S. holder on the sale, exchange, redemption, retirement or other taxable disposition of a Note generally will not be subject to U.S. federal income and withholding tax, unless:

• such gain is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States and, if the non-U.S. holder is entitled to the benefits under an applicable tax treaty, is attributable to a permanent establishment or a fixed base in the United States; or

• the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are satisfied.

If the first bullet point applies, the non-U.S holder generally will be subject to U.S. federal income tax with respect to such gain in the same manner as U.S. holders, as described above, unless an applicable income tax treaty provides otherwise. In addition, if such non-U.S holder is a corporation, such non-U.S. holder may also be subject to the branch profits tax described above. If the second bullet point applies, the non-U.S holder generally will be subject to U.S. federal income tax at a rate of 30% (or at a reduced rate under an applicable income tax treaty) on the amount by which capital gains from U.S. sources (including gains from the sale, exchange, redemption, retirement or other disposition of the Notes) exceed capital losses allocable to U.S. sources.

Recently Enacted Legislation

A U.S. federal withholding tax at a 30% rate will apply to interest payments made after December 31, 2013 and proceeds in respect of a sale of debt obligations occurring after December 31, 2016 received by certain non-U.S. holders (or U.S. holders holding through foreign accounts or intermediaries), if certain disclosure requirements related to U.S. ownership or accounts are not satisfied. In general, this new withholding tax is not expected to apply to obligations that are issued prior to January 1, 2014. If the Notes were “significantly modified” on or after January 1, 2014 in such a way that they were considered to be re-issued for U.S. federal income tax purposes, this legislation could apply to interest payments and proceeds of sale in respect of the Notes. If we are required to withhold any U.S. federal withholding tax on payments made to any holder of our Notes, we will pay such withheld amount to the IRS. That payment, if made, will be treated as a payment of cash to the holder of the Notes with respect to whom the payment was made and will reduce the amount of cash to which such holder would otherwise be entitled.

Information Reporting and Backup Withholding

If you are a U.S. holder, payments of principal and interest made by us on, or the proceeds of the sale or other disposition of, the Notes may be subject to information reporting. In addition, if you are a U.S. holder, such payments generally will be subject to U.S. federal backup withholding tax unless you supply a taxpayer identification number, certified under penalties of perjury, as well as certain other information or otherwise establish an exemption from backup withholding. If you are a non-U.S. holder, information reporting may apply with respect to payments on the Notes. In addition, if you are a non-U.S. holder, you may be required to comply with certification procedures to establish that you are not a U.S. person in order to avoid backup withholding tax with respect to our payments on, or the proceeds from the disposition of, Notes. The backup withholding tax rate is currently 28%. Any amounts withheld under the backup withholding rules may be allowable as a refund or a credit against the holder’s U.S. federal income tax liability, provided required information is furnished to the IRS.

S-26

UNDERWRITING

In accordance with the terms and conditions contained in the underwriting agreement, dated the date of this prospectus supplement, between us and MLV & Co. LLC and JMP Securities LLC, on their own behalf and as the representatives of Compass Point Research & Trading, LLC, Maxim Group LLC, National Securities Corporation and Northland Securities, Inc., we have agreed to issue and sell to the public through the underwriters, and the underwriters have agreed to offer and sell, up to $25,000,000 aggregate principal amount of Notes, on a best efforts basis.

The underwriting agreement provides that the obligation of the underwriters to offer and sell the Notes, on a best efforts basis, is subject to certain conditions precedent, including but not limited to delivery of legal opinions. The underwriters are under no obligation to purchase any Notes for their own account. As a “best efforts” offering, there can be no assurance that the offering contemplated hereby will ultimately be consummated. The underwriters may, but are not obligated to, retain other selected dealers that are qualified to offer and sell the Notes and that are members of the Financial Industry Regulatory Authority.

We will have no obligation to sell any Notes to the underwriters unless, upon issuance, there are at least 1 million publicly held Notes in the U.S., held by at least 400 holders in the U.S., with an aggregate market value of at least $4 million in the U.S., such that the Notes would be eligible for listing on the NYSE.

We have been advised by the representatives of the underwriters that the underwriters propose to offer the Notes to investors at the public offering price set forth on the cover of this prospectus supplement. There is no arrangement for funds to be received in escrow, trust or similar arrangement. In connection with the offer and sale of the Notes by the underwriters, we will pay the underwriters an amount equal to 3.15% of the gross proceeds received by us in connection with the sale of the Notes, which will be deemed underwriting commissions.

A copy of the underwriting agreement will be filed as an exhibit to the registration statement of which this prospectus supplement forms a part.

Any Notes sold by the underwriters to securities dealers will be sold at the public offering price less a selling concession not in excess of $0.50 per Note.

We estimate that our portion of the total expenses of this offering, exclusive of the underwriting commissions described above but including reimbursement of certain expenses of the underwriters, will be approximately $175,000.

We are not under any contractual obligation to engage any of the underwriters to provide investment banking, lending, asset management or financial advisory services to us in the future. If any of the underwriters provide such services to us after this offering, we may pay such underwriter fair and reasonable fees that would be determined at that time in an arm’s length negotiation. However, we will not enter into any agreement with any of the underwriters, nor will we pay any fees for such services to any of the underwriters, prior to the date which is 90 days after the date of this offering, unless the Financial Industry Regulatory Authority, Inc. determines that such payment would not be deemed underwriters’ compensation in connection with the offering.

Northland Capital Markets is the trade name for certain equity capital markets and investment banking activities of Northland Securities, Inc., member FINRA/SIPC.

ABOUT THIS PROSPECTUS

This prospectus is part of a registration statement that we have filed with the Securities and Exchange Commission, or the SEC, utilizing a “shelf” registration process. This prospectus provides you with a general description of the securities we may issue and sell. Each time we issue and sell securities, we will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may add, update or change information in this prospectus. If there is any inconsistency between the information in this prospectus and the prospectus supplement, you should rely solely on the information in the prospectus supplement. You should read both this prospectus and the prospectus supplement applicable to any offering, together with the additional information described under the heading “Incorporation by Reference of Information Filed With the SEC.”

We have filed or incorporated by reference exhibits to the registration statement of which this prospectus forms a part. You should read the exhibits carefully for provisions that may be important to you. See “Where You Can Find More Information.”

You should rely only on the information contained or incorporated by reference in this prospectus and any prospectus supplement. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We will not make an offer to sell our securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus, as well as information we previously filed with the SEC and have incorporated by reference, is accurate as of the date on the front cover of this prospectus only.

Any one of the risk factors discussed, or other factors, could cause actual results to differ materially from expectations and could adversely affect our business, financial condition and results of operations. These risks are interrelated, and you should treat them as a whole. The risks described are not the only risks that may affect us. Additional risks and uncertainties not presently known to us or not identified, may also materially and adversely affect our business, financial condition and results of operations. Before making an investment decision, you should carefully consider the risk factors incorporated by reference to our most recent Annual Report on Form 10-K, as updated and supplemented by our periodic reports and other information filed by us with the SEC and incorporated by reference herein, in addition to the other information contained or incorporated by reference in this prospectus and any accompanying prospectus supplement. In connection with the forward-looking statements that appear in this prospectus, you should also carefully review the cautionary statements referred to in “Forward-Looking Information.”

OUR COMPANY

General

Arlington Asset Investment Corp. is a holding company that through its subsidiaries acquires mortgage-related and other assets. We acquire on a leveraged basis, residential mortgage-backed securities, or MBS, either issued by a U.S. Government agency, or guaranteed as to principal and interest by U.S. Government agencies or U.S. Government-sponsored entities (agency-backed MBS). We also acquire MBS issued by private organizations (private-label MBS) as well as other assets, in each case, subject to maintaining our exemption from regulation as an investment company under the Investment Company Act of 1940, as amended, or the 1940 Act. We are a Virginia corporation taxed as a C corporation for U.S. federal income tax purposes.

Our Principal Office

Our principal executive offices are located at Potomac Tower, 1001 Nineteenth Street North, Arlington, Virginia, 22209.

USE OF PROCEEDS

Except as may be set forth in a particular prospectus supplement, we will use the net proceeds from sales of securities for the acquisition of MBS, either issued by a U.S. Government agency, or guaranteed as to principal and interest by U.S. Government agencies or U.S. Government-sponsored entities or issued by private organizations, as well as for the acquisition of other assets. We may also use the proceeds for other general corporate purposes such as repayment of outstanding indebtedness, pursuit of growth initiatives that may include acquisitions, working capital, and for liquidity needs. Pending the application of the net proceeds, we expect to invest the net proceeds in short-term marketable securities or use the net proceeds to reduce our short-term indebtedness.

RATIO OF EARNINGS TO FIXED CHARGES AND OF EARNINGS TO COMBINED FIXED

CHARGES AND PREFERRED STOCK DIVIDENDS

The following table sets forth our consolidated ratios of earnings to fixed charges and of earnings to combined fixed charges and preferred stock dividends for each of the last five fiscal years. For purposes of calculating the ratio of earnings to fixed charges, earnings are defined as income before income taxes and fixed charges (excluding capitalized interest). Fixed charges include interest (whether capitalized or expensed), amortization of debt issuance costs and any discount or premium relating to any indebtedness (whether capitalized or expensed) and the portion of rent expense determined to represent interest. Because we did not have any preferred stock outstanding and therefore paid no preferred stock dividends during any of the periods presented, the ratio of earnings to combined fixed charges and preferred stock dividends is identical to the ratio of earnings to fixed charges for each of the periods presented.

			Fiscal Year Ended December 31,
	Nine Months  Ended September 30, 2010		2009		2008			2007			2006			2005
Ratio of Earnings to Fixed Charges		22.4		39.0		(A	)		(A	)		(A	)		(A	)

(A) Due to the company’s losses in 2008, 2007, 2006 and 2005, the ratio coverage in these years was less than 1:1. The company would have had to generate additional earnings of $295,848, $658,791, $61,042, and $220,601, respectively, to achieve coverage of 1:1 in those years.

Under our articles of incorporation, the total number of shares of all classes of stock that we have authority to issue is 575,000,000 of which 450,000,000 are shares of Class A common stock, par value $.01 per share, 100,000,000 are share of Class B common stock, par value $.01 per share, and 25,000,000 are shares of preferred stock, par value $.01 per share of which 100,000 are shares of Series A junior preferred stock. As of December 31, 2010, 7,106,330 shares of Class A common stock were issued and outstanding, 566,112 shares of Class B common stock were issued and outstanding, and no shares of preferred stock were issued and outstanding.

Common Stock

Subject to any preferential or other rights of any outstanding series of preferred stock that may be designated by our Board of Directors, the holders of shares of common stock are entitled to receive such dividends as may be declared from time to time by our Board of Directors from funds available therefor. All decisions regarding the declaration and payment of dividends will be at the discretion of our Board of Directors and will be evaluated on a quarterly basis in light of our financial condition, earnings, growth prospects, funding requirements, applicable law and other factors our Board of Directors deems relevant.

The holders of shares of Class A common stock are entitled to one vote for each share on all matters voted on by shareholders and the holders of shares of Class B common stock are entitled to three votes per share on all maters voted on by shareholders. Each of the holders of Class A common stock and Class B common stock possess all voting power, except as otherwise required by law or provided in any resolution adopted by our Board of Directors with respect to any series of our preferred stock. Our Board of Directors consists of seven Directors. The Directors are elected at each annual meeting of shareholders. Provided a quorum has been properly established in accordance with our bylaws, the holders of a plurality of shares of common stock voting for the election of our Directors can elect all of the Directors, if they choose to do so, subject to any rights of the holders of preferred stock to elect Directors. Except for directors elected by the holders of outstanding shares of preferred stock as a separate voting group, any director may be removed from office with or without cause by the affirmative vote of the holders of at least two-thirds of the voting power of all outstanding shares of the company entitled to vote generally in the election of directors. There are no cumulative voting rights. Shares of our Class B common stock may convert into shares of our Class A common stock at our option in certain circumstances, including (1) upon a sale, transfer gift, assignment, devise or other disposition and (2) at the time the holder of shares of Class B common stock ceases to be employed by us.

Subject to the rights of any outstanding series of preferred stock and except as otherwise required by law or pursuant to the listing standards of the exchange on which our securities are listed, in all matters other than the election of directors, certain amendments of our bylaws or certain provisions of our articles of incorporation, the affirmative vote of the holders of a majority of shares of common stock present in person or represented by proxy at a meeting of shareholders and entitled to vote on the subject matter is required for approval, provided a quorum is established. For more information regarding the voting rights of our capital stock, see “Important Provisions of Virginia Law and Our Articles of Incorporation, Bylaws and Shareholder Rights Agreement.”

When we issue shares of our common stock, for and in receipt of consideration approved by our Board of Directors, the shares will be fully paid and nonassessable, which means that the full purchase price of the shares will have been paid and holders of the shares will not be assessed any additional monies for the shares. There may be restrictions imposed by applicable securities laws on any transfer of shares of our common stock. Holders of our common stock have no redemption rights, conversion rights or preemptive rights to purchase or subscribe for our securities. There are no redemption provisions or sinking fund provisions applicable to our common stock.

In the event of our liquidation, dissolution or winding up, the holders of Class A common stock and Class B common stock are entitled to share ratably in all of our assets that are legally available for distribution after payment of or adequate provision for all of our known debts and other liabilities and subject to any preferential rights of holders of preferred stock, if any preferred stock is outstanding at such time.

The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of any series of preferred stock that we may designate and issue in the future.

Preferred Stock

Our Board of Directors is authorized without further shareholder approval (except as may be required by applicable law or the regulations promulgated on any exchange on which our securities are listed) to provide for the issuance of shares of preferred stock, in one or more series, and to fix for each such series such voting powers, designations, preferences and relative, participating, optional and other special rights, and such qualifications, limitations, or restrictions, as are stated in the resolution adopted by our Board of Directors providing for the issuance of such series and as are permitted by the Virginia Stock Corporation Act.

DESCRIPTION OF DEPOSITARY SHARES

This section describes some of the general terms and provisions applicable to the depositary shares and depositary receipts that we may issue from time to time, other than pricing and related terms. We will describe the specific terms of a series of depositary shares and the deposit agreement in the applicable prospectus supplement. The following description and any description of the depositary shares in the applicable prospectus supplement may not be complete and is subject to and qualified in its entirety by reference to the terms and provisions of the applicable deposit agreement, which we will file with the SEC in connection with an issuance of depositary shares and depositary receipts. You should read the description included in the applicable prospectus supplement, together with the more detailed provisions of the applicable deposit agreement, for provisions that may be important to you.

We may issue depositary shares evidenced by depositary receipts representing interests in shares of a particular series of preferred stock. We will deposit the preferred stock of a series that is the subject of depositary shares with a depositary, which will hold that preferred stock for the benefit of the holders of the depositary shares, in accordance with a deposit agreement between the depositary and us. The holders of depositary shares will be entitled to all the rights and preferences of the preferred stock to which the depositary shares relate, including dividend, voting, conversion, redemption and liquidation rights, to the extent of their interests in that preferred stock.

While the deposit agreement relating to a particular series of preferred stock may have provisions applicable solely to that series of preferred stock, unless otherwise stated in the applicable prospectus supplement, all deposit agreements relating to preferred stock we issue will include the following provisions:

Dividends and Other Distributions

Each time we pay a cash dividend or make any other type of cash distribution with regard to preferred stock of a series, the depositary will distribute to the holder of record of each depositary share relating to that series of preferred stock an amount equal to the dividend or other distribution per depositary share that the depositary receives. If there is a distribution of property other than cash, the depositary either will distribute the property to the holders of depositary shares in proportion to the depositary shares held by each of them, or the depositary will, if we approve, sell the property and distribute the net proceeds to the holders of the depositary shares in proportion to the depositary shares held by them.

Withdrawal of Preferred Stock

A holder of depositary shares will be entitled to receive, upon surrender of depositary receipts representing depositary shares, the number of whole or fractional shares of the applicable series of preferred stock, and any money or other property, to which the depositary shares relate.

Redemption of Depositary Shares

Whenever we redeem shares of preferred stock held by a depositary, the depositary will be required to redeem, on the same redemption date, depositary shares constituting, in total, the number of shares of preferred stock held by the depositary that we redeem, subject to the depositary’s receiving the redemption price of those shares of preferred stock. If fewer than all the depositary shares relating to a series are to be redeemed, the depositary shares to be redeemed will be selected by lot or by another method we determine to be equitable.

Voting

Any time we send a notice of meeting or other materials relating to a meeting to the holders of a series of preferred stock to which depositary shares relate, we will provide the depositary with sufficient copies of those

6

materials so they can be sent to all holders of record of the applicable depositary shares. The depositary will send those materials to the holders of record of the depositary shares on the record date for the meeting. The depositary will solicit voting instructions from holders of depositary shares and will vote or not vote the preferred stock to which the depositary shares relate in accordance with those instructions.

Liquidation Preference

Upon our liquidation, dissolution or winding up, the holder of each depositary share will be entitled to what the holder of the depositary share would have received if the holder had owned the number of shares (or fraction of a share) of preferred stock which is represented by the depositary share.

Conversion

If shares of a series of preferred stock are convertible into common stock or other of our securities or property, holders of depositary shares relating to that series of preferred stock will, if they surrender depositary receipts representing depositary shares and appropriate instructions to convert them, receive the shares of common stock or other securities or property into which the number of shares (or fractions of shares) of preferred stock to which the depositary shares relate could at the time be converted.

Amendment and Termination of a Deposit Agreement

We and the depositary may amend a deposit agreement and the form of depositary receipt, except that an amendment which materially and adversely affects the rights of holders of depositary shares, or would be materially and adversely inconsistent with the rights granted to the holders of the preferred stock to which they relate, must be approved by holders of at least two-thirds of the outstanding depositary shares. No amendment will impair the right of a holder of depositary shares to surrender the depositary receipts evidencing those depositary shares and receive the preferred stock to which they relate, except as required to comply with law. We may terminate a deposit agreement with the consent of holders of a majority of the depositary shares to which it relates. Upon termination of a deposit agreement, the depositary will make the whole or fractional shares of preferred stock to which the depositary shares issued under the deposit agreement relate available to the holders of those depositary shares. A deposit agreement will automatically terminate if:

• all outstanding depositary shares to which it relates have been redeemed;

• each share of preferred stock has been converted into or exchanged for common stock; or

• the depositary has made a final distribution to the holders of the depositary shares issued under the deposit agreement upon our liquidation, dissolution or winding up.

Miscellaneous

There may be provisions: (a) requiring the depositary to forward to holders of record of depositary shares any reports or communications from us which the depositary receives with respect to the preferred stock to which the depositary shares relate; (b) regarding compensation of the depositary; (c) regarding resignation of the depositary; (d) limiting our liability and the liability of the depositary under the deposit agreement (usually to failure to act in good faith, gross negligence or willful misconduct); and (e) indemnifying the depositary against certain possible liabilities.

DESCRIPTION OF DEBT SECURITIES

The following summary of selected provisions of the indentures does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the indenture that will be filed with the SEC in connection with an offering of our debt securities. Moreover, the terms of any series of debt securities

7

offered by us may differ from the general description of terms presented below. Each of the open-ended senior indenture and open-ended subordinated indenture has been filed as an exhibit to the registration statement of which this prospectus is a part and has been qualified or will be qualified as an indenture under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. The particular terms of any debt securities we offer will be described in the applicable prospectus supplement, along with any applicable modifications of or additions to the general terms of the debt securities described below and in the indentures. You should read that description and the description set forth below, together with the more detailed provisions of the applicable indenture, including the defined terms, which we will file with the SEC in connection with the offering, for provisions that may be important to you. You should also consider applicable provisions of the Trust Indenture Act.

We may from time to time issue and sell debt securities. These debt securities are described below and will be senior debt securities or subordinated debt securities and any senior or subordinated debt securities that may be part of a unit, all of which are called debt securities. The senior debt securities and subordinated debt securities will be issued under one or more separate indentures between us and the indenture trustee named in the applicable prospectus supplement. Senior debt securities will be issued under a senior indenture and subordinated debt securities will be issued under a subordinated indenture, and in some cases pursuant to a supplemental indenture thereto. Together, the senior indenture and the subordinated indenture are called the indentures, and the senior indenture trustee and the subordinated indenture trustee are called the indenture trustees.

General

The debt securities will be our direct obligations. Unless we indicate otherwise in the applicable prospectus supplement, the indentures do not significantly limit our operations. Unless we indicate otherwise in the applicable prospectus supplement, in particular, the debt securities do not:

• limit the amount of debt securities that we can issue under the indentures;

• limit the number of series of debt securities that we can issue from time to time;

• restrict us from reopening a previous issue of debt securities to issue additional debt securities of that series;

• limit or otherwise restrict the total amount of debt that we or our subsidiaries may incur or the amount of other securities that we may issue;

• require us or an acquiror to repurchase debt securities in the event of a “change in control”; or

• contain any covenant or other provision that is specifically intended to afford any holder of the debt securities any protection in the event of highly leveraged transactions or similar transactions involving us or our subsidiaries.

The senior debt securities will rank senior to our subordinated debt securities.

Terms

Any series of debt securities offered by us will include specific terms, including some or all of the following:

• the title, series, form and type of the offered debt securities;

• the aggregate principal amount of the offered debt securities and any limit upon the aggregate principal amount of the debt securities of such title or series;

• the date or dates (including the maturity date) or method, if any, for determining such dates, on which the principal of the offered debt securities will be payable (and any provisions relating to extending or shortening the date on which the principal of the offered debt securities is payable);

8

• the interest rate, or method, if any, for determining the interest rate, the date or dates from which interest will accrue, or method, if any, for determining such dates, the interest payment dates, if any, on which interest will be payable, and whether and under what circumstances additional amounts on the offered debt securities will be payable; the manner in which payments with respect to the offered debt securities will be made; and the place or places where principal or, premium, if any, interest and additional amount, if any, will be payable;

• whether the offered debt securities are redeemable at our option, and if so, the periods, prices, and other terms regarding such optional redemption;

• whether we are obligated to redeem or repurchase the offered debt securities pursuant to any sinking fund or at the option of any holder thereof, and if so, the periods, prices and other terms regarding such repurchase or redemption;

• the currency for payment of principal, premium, interest and any additional amount with respect to the offered debt securities, whether the principal, premium, if any, interest or additional amounts, if any, with respect to the offered debt securities are to be payable, at our election or any holder’s election, in a currency other than that in which the offered debt securities are denominated, the period in which that election may be made and the time and manner of determining the applicable exchange rate;

• whether the amount of payments of principal of, premium, if any, interest on, or additional amounts, if any, with respect to the offered debt securities may be determined by reference to an index, formula or other method, and if so, the terms and conditions and the manner in which such amounts will be determined and paid or payable;

• whether the offered debt securities will be convertible into or exchangeable for our common stock or other securities, and if so, the initial conversion or exchange price and the periods and terms of the conversion or exchange; and

• any other terms not inconsistent with the provisions of the indentures filed as exhibits to the accompanying prospectus supplements.

Form of the Debt Securities

The indentures provide that we may issue senior and subordinated debt securities in registered form, in bearer form or in both registered and bearer form. Unless we indicate otherwise in the applicable prospectus supplement, each series of senior and subordinated debt securities will be issued in registered form, without coupons. Holders of “registered form” securities are listed on the applicable indenture trustee’s register for the applicable debt securities.

Unless we indicate otherwise in the applicable prospectus supplement, we will issue senior and subordinated debt securities in denominations of $1,000 or any integral multiple of $1,000, and we will issue senior and subordinated debt securities in bearer form in denominations of $5,000 or any integral multiple of $5,000. There will be no service charge for any registration of transfer, exchange, redemption or conversion of senior or subordinated debt securities, but we or the applicable indenture trustee may require the holder to pay any tax or other governmental charge that may be imposed in connection with any registration of a transfer or exchange of the senior or subordinated debt securities, other than certain exchanges not involving any transfer.

If we issue the debt securities in bearer form, the debt securities will have interest coupons attached. “Bearer form” securities are payable to whomever physically holds them from time to time. Debt securities in bearer form will not be offered, sold, resold or delivered in connection with their original issuance in the United States or to any United States person other than through offices of certain United States financial institutions located outside the United States. Purchasers of debt securities in bearer form will be subject to certification procedures and may be affected by United States tax law limitations.

9

Registration, Transfer, Payment and Paying Agent

Unless we indicate otherwise in the applicable prospectus supplement, payments on the debt securities will be made at our office or agency maintained for that purpose. Unless otherwise indicated in the applicable prospectus supplement, the corporate trust office of the indenture trustee in the City of New York will be designated as our sole paying agent for payments with respect to the debt securities of each series. Any transfer of the debt securities will be registrable at the same place. In addition, we may choose to pay interest by check mailed to the address in the security register of the person in whose name the debt security is registered at the close of business on the applicable record date. Unless we indicate otherwise in the applicable prospectus supplement, any interest and any additional amounts with respect to any debt securities which is payable, but not punctually paid or duly provided for, may be paid to the holders as of a special record date fixed by the applicable indenture trustee or in any other lawful manner.

Unless we indicate otherwise in the applicable prospectus supplement, payments of principal, premium, if any, and interest on debt securities in bearer form will be made at the office outside the United States specified in the applicable prospectus supplement and as we may designate from time to time. Payment can also be made by check or by transfer to an account maintained by the payee with a bank located outside the United States. Unless we indicate otherwise in the applicable prospectus supplement, payment on debt securities in bearer form will be made only if the holder surrenders the coupon relating to the interest payment date. We will not make any payments on any debt security in bearer form at any office or agency in the United States, by check mailed to any address in the United States or by transfer to any account maintained with a bank located in the United States.

Global Debt Securities

Unless we indicate otherwise in the applicable prospectus supplement for a series of debt securities, each series of debt securities will be issued in global form, which means that we will deposit with the depositary identified in the applicable prospectus supplement (or its custodian) one or more certificates representing the entire series, as described below under “Book-Entry Procedures and Settlement.” Global debt securities may be issued in either temporary or permanent form.

The applicable prospectus supplement will describe any limitations and restrictions relating to a series of global senior or subordinated debt securities.

Covenants

The following covenants will apply to us with respect to the debt securities of each series unless otherwise specified in the applicable prospectus supplement:

• Except as described in this prospectus under “Description of Debt Securities—Consolidation, Merger and Sale of Assets,” we must do or cause to be done all things necessary to preserve and keep in full force and effect our existence, rights and franchises. However, we are not required to preserve any right or franchise if we determine that its preservation is no longer desirable in the conduct of our business and that its loss is not disadvantageous in any material respect to the holders of the debt securities.

• We are required to pay or discharge or cause to be paid or discharged (a) all taxes, assessments and governmental charges levied or imposed upon us or any subsidiary or upon our income, profits or property or the income, profits or property of any subsidiary and (b) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon our property or the property of any subsidiary. We must pay these taxes and other claims before they become delinquent. However, we are not required to pay or discharge or cause to be paid or discharged any tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.

Additional covenants described in the applicable prospectus supplement may apply to us with respect to a particular series of debt securities.

10

Subordination of Subordinated Debt Securities

Contractual provisions in the subordinated debt indenture may prohibit us from making payments on the subordinated debt securities, which are subordinate and junior in right of payment to the extent and in the manner stated in the subordinated debt indenture, to all of our senior debt, as defined in the subordinated debt indenture, as it may be supplemented from time to time, including all debt securities we have issued and will issue under the senior debt indenture.

The subordinated debt indenture defines “senior debt” as the principal of and premium, if any, and interest on all indebtedness of us, other than the subordinated debt securities, whether outstanding on the date of the indenture or thereafter created, incurred or assumed, which is (a) for money borrowed, (b) evidenced by a note or similar instrument given in connection with the acquisition of any businesses, properties or assets of any kind or (c) obligations of us as lessee under leases required to be capitalized on the balance sheet of the lessee under generally accepted accounting principles or leases of property or assets made as part of any sale and lease-back transaction to which we are a party. For the purpose of this definition, “interest” includes interest accruing on or after the filing of any petition in bankruptcy or for reorganization relating to us to the extent that the claim for post-petition interest is allowed in the proceeding. Also for the purpose of this definition, “indebtedness of us” includes indebtedness of others guaranteed by us and amendments, renewals, extensions, modifications and refundings of any indebtedness or obligation of the kinds described in the first sentence of this paragraph, but does not include any indebtedness or obligation if the instrument creating or evidencing the indebtedness or obligation, or under which the indebtedness or obligation is outstanding, provides that the indebtedness or obligation is not superior in right of payment to the subordinated debt securities.

Unless we indicate otherwise in the applicable prospectus supplement, the subordinated debt indenture provides that, unless all principal of and any premium or interest on the senior debt has been paid in full, no payment or other distribution may be made in respect of any subordinated debt securities in the following circumstances:

• in the event of any insolvency or bankruptcy proceedings, or any receivership, liquidation, reorganization or other similar proceeding involving us or our assets;

• in the event of any liquidation, dissolution or other winding up of us, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy;

• in the event of any assignment for the benefit of creditors or any other marshalling of assets and liabilities of us;

• if any subordinated debt securities of ours have been declared due and payable before their stated maturity; or

• (a) in the event and during the continuation of any default in the payment of principal, premium or interest on any senior debt beyond any applicable grace period or if any event of default with respect to any senior debt of ours has occurred and is continuing, permitting the holders of that senior debt of ours or an indenture trustee to accelerate the maturity of that senior debt, unless the event of default has been cured or waived or ceased to exist and any related acceleration has been rescinded, or (b) if any judicial proceeding is pending with respect to a payment default or an event of default described in (a).

If the indenture trustee under the subordinated debt indenture or any holders of the subordinated debt securities receive any payment or distribution that they know is prohibited under the subordination provisions, then the applicable indenture trustee or the holders will have to repay that money to the holders of the senior debt.

Even if the subordination provisions prevent us from making any payment when due on the subordinated debt securities of any series, we will be in default on our obligations under that series if we do not make the payment when due. This means that the indenture trustee under the subordinated debt indenture and the holders of that series can take action against us, but they will not receive any money until the claims of the holders of senior debt have been fully satisfied.

11

Consolidation, Merger and Sale of Assets

Each indenture generally permits a consolidation or merger between us and another corporation and the conveyance, transfer or lease by us of all or substantially all of our property or assets, in each case without the consent of the holders of any outstanding debt securities. However, unless we indicate otherwise in the applicable prospectus supplement, each indenture requires that:

• the successor or purchaser is a corporation organized under the laws of the United States of America, any state thereof or the District of Columbia and expressly assumes our obligations on the debt securities under the applicable indenture;

• immediately after giving effect to the transaction, no event which, after notice or lapse of time, would become an event of default, will have occurred and be continuing pursuant to the applicable indenture; and

• either we or the successor person has delivered to the applicable indenture trustee an officer’s certificate and an opinion of counsel stating the consolidation, merger, transfer or lease, as applicable, complied with these provisions and all conditions precedent of the applicable indenture.

The successor shall be substituted for us as if it had been an original party to the indentures and the debt securities. Thereafter, the successor may exercise our rights and powers under the indentures and the debt securities and, except in the case of a lease, we will be released from all of our obligations and covenants under those documents.

Exchange of Debt Securities

Registered debt securities may be exchanged for an equal aggregate principal amount of registered debt securities of the same series containing identical terms and provisions in authorized denominations requested by the holders upon surrender of the registered debt securities at an office or agency that we maintain for that purpose and upon fulfillment of all other requirements set forth in the indentures.

Conversion and Exchangeability

The holders of debt securities that are convertible into or exchangeable for our common stock or other securities will be entitled to convert or exchange the debt securities under some circumstances. The terms of any conversion or exchange right will be described in the applicable prospectus supplement. The terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option, and may include provisions pursuant to which the number of shares of our common stock or other securities to be received by the holders of the debt securities would be subject to adjustment.

Events of Default

Unless we indicate otherwise in the applicable prospectus supplement for any series of debt securities, events of default with respect to any series of debt securities are:

• failure to pay the interest or any additional amounts payable on any debt security of such series when due and continuance of that default for 30 days;

• failure to pay the principal of or any premium on any debt security of such series when due and payable;

• failure to deposit any sinking fund payment when and as due by the terms of any debt security of such series;

• failure to perform or the breach of any covenant or warranty in the applicable indenture or the debt securities (other than a covenant or warranty included solely for the benefit of a series of debt securities

12

other than such series) that continues for 60 days after we are given written notice by the applicable indenture trustee or we and the applicable indenture trustee are given written notice by the holders of at least 25% of the outstanding debt securities of such series; or

• certain events involving our bankruptcy, insolvency or reorganization.

If an event of default with respect to debt securities of any series occurs and is continuing, the applicable indenture trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice in writing to us, and to the applicable indenture trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, on that series to be due and payable immediately. The indenture trustee may withhold notice to the holders of debt securities of any default or event of default, except a default or event of default relating to the payment of principal or interest, if it determines that withholding such notice is in the holders’ interest.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to such series and its consequences, except a continuing default or events of default in the payment of principal, premium, if any, or interest on the debt securities of such series.

Any such waiver shall cure such default or event of default.

Unless we indicate otherwise in the applicable prospectus supplement, subject to the terms of the indentures, if an event of default under an indenture shall occur and be continuing, the applicable indenture trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the applicable indenture trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the applicable indenture trustee, or exercising any trust or power conferred on the applicable indenture trustee, with respect to the debt securities of that series, subject to certain limitations specified in the applicable indenture.

Unless we indicate otherwise in the applicable prospectus supplement, a holder of the debt securities of any series will only have the right to institute a proceeding under the indentures or to appoint a receiver or trustee, or to seek other remedies if:

• The holder has given written notice to the applicable indenture trustee of a continuing event of default with respect to that series;

• The holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request, and such holders have offered reasonable indemnity to the applicable indenture trustee to institute such proceedings as trustee; and

• the applicable indenture trustee does not institute such proceeding, and does not receive from the holders of a majority in the aggregate principal amount of the outstanding debt securities of that series other conflicting directions within 60 days after such notice, request and offer.

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

We will periodically file statements with the applicable indenture trustee regarding our compliance with certain of the covenants in the indentures.

Waivers of Certain Covenants and Past Defaults

Unless we indicate otherwise in the applicable prospectus supplement, the holders of at least 25% of the aggregate principal amount of the outstanding senior and subordinated debt securities of each series may, on

13

behalf of all holders of that series, waive our compliance with certain restrictive provisions of the applicable indenture. They also may waive any past default with respect to that series under the applicable indenture, except (a) a default in the payment of principal, premium or interest or any additional amounts or (b) a default in the performance of certain covenants which cannot be modified without the consent of all of the holders of the applicable series.

Amendments to the Indentures

Supplemental Indentures with Consent of Holders

Unless we indicate otherwise in the applicable prospectus supplement, we and the applicable trustee may modify or amend an indenture, with the consent of the holders of at least 25% in principal amount of each series of the senior or subordinated debt securities affected by the modification or amendment. However, unless we indicate otherwise in the applicable prospectus supplement, no modification or amendment may, without the consent of each holder affected by the modification or amendment:

• change the due date of the principal of, or any premium or installment of interest on, or any additional amounts with respect to any debt security;

• reduce the principal amount of, or the rate of interest on, or any additional amounts or premium, if any, payable with respect to any debt security, or, except as otherwise permitted, change an obligation to pay additional amounts with respect to any debt security, or adversely affect the right of repayment at the option of any holder, if any;

• change the place of payment, the currency in which the principal of, premium, if any, or interest on, or any additional amounts with respect to any debt security is payable or impair the right to institute suit for the enforcement of any such payment on or after the due date thereof (or, in the case of redemption, on or after the redemption date or, in the case of repayment at the option of the holder, on or after the date for repayment);

• reduce the percentage in principal amount of outstanding debt securities of any series the consent of whose holders is required for any supplemental indenture, or the consent of whose holders is required for any waiver (of compliance with certain provisions of the applicable indenture or certain defaults thereunder and their consequences) under the applicable indenture or reduce requirements for quorum or voting;

• modify any of the provisions in the applicable indenture provisions described above under “Waivers of Certain Covenants and Past Defaults” and in this section “Amendments to the Indentures—Supplemental Indentures with Consent of Holders,” except to increase any percentage in principal amount of outstanding debt securities of any series the consent of whose holders is required for a supplemental indenture or waiver, or to provide that certain other provisions of the applicable indenture cannot be modified or waived without the consent of the holders of each outstanding debt security affected thereby;

• adversely affect the right of any holder to convert any convertible debt securities; or

• in the case of the subordinated indenture, modify the subordination provisions in a manner adverse to the holders of the subordinated debt securities.

Supplemental Indentures without Consent of Holders

Except as otherwise provided in the applicable prospectus supplement, we and the applicable indenture trustee may modify and amend an indenture without the consent of any holder for any of the following purposes:

• to evidence the succession of another person to us, and the assumption by the successor of our covenants in the applicable indenture and in the debt securities;

14

• to establish the form or terms of debt securities of any series and any related coupons;

• to evidence and provide for the acceptance of appointment by a successor trustee and to add to or change any provisions of the applicable indenture as necessary to provide for or facilitate the administration of the trusts under the applicable indenture by more than one trustee;

• to cure any ambiguity or to correct or supplement any provision in the applicable indenture that may be defective or inconsistent with any other provision of the applicable indenture, or to make any other provisions with respect to matters or questions arising under the applicable indenture which do not adversely affect the interests of the holders of any debt securities or related coupons in any material respect;

• to modify the conditions, limitations and restrictions on the authorized amount, terms or purposes of issue, authentication and delivery of debt securities;

• to add additional events of default with respect to all or any series of debt securities;

• to supplement any of the provisions of the applicable indenture to the extent necessary to permit or facilitate the defeasance and discharge of any series of debt securities, provided the action does not adversely affect the interests of the holders of any debt securities of that series or related coupons or any other debt securities or related coupons in any material respect;

• to secure the debt securities;

• to amend or supplement any provision of the applicable indenture or any supplemental indenture, provided that the amendment or supplement does not materially adversely affect the interests of the holders of outstanding debt securities; and

• to make certain provisions with respect to conversion rights.

Legal Defeasance and Covenant Defeasance

If the applicable prospectus supplement provides for defeasance, subject to the terms described therein, we may at any time elect to defease and will be deemed to have paid and discharged our obligations on the applicable debt securities if:

• no event of default has occurred and is continuing, or would occur upon the giving of notice or lapse of time, at the time of the satisfaction and discharge;

• either (a) we have irrevocably deposited with the applicable indenture trustee sufficient cash or government securities to pay when due all the principal of, premium, if any, interest on and additional amounts, if any, with respect to the applicable debt securities, through the stated maturity or redemption date of the applicable debt securities (or, in the case of debt securities which have become due and payable, through the date of such deposit), or (b) we have properly fulfilled such other means of satisfaction and discharge as is provided in or pursuant to the applicable indenture for the applicable debt securities;

• we have paid all other sums payable under the applicable indenture with respect to the applicable debt securities and any related coupons;

15

• we have delivered to the applicable indenture trustee a certificate of our independent public accountants certifying as to the sufficiency of the amounts deposited by us, and an officers’ certificate and opinion of counsel as required by the applicable indenture; and

In the case of a defeasance, the holders of the applicable debt securities of the series will not be entitled to the benefits of the applicable indenture, except for the registration of transfer or exchange and the replacement of stolen, lost or mutilated applicable debt securities and the requirements regarding the maintenance of an office or agency where the applicable debt securities can be surrendered for payment or registration of transfer or exchange and the right of the holders of the applicable debt securities to receive from the deposited funds payment of the principal of, premium, if any, interest, and additional amounts, if any, with respect to the applicable debt securities when due.

Determining the Outstanding Debt Securities

Unless otherwise provided in or pursuant to the applicable indenture, we will consider the following factors in determining whether the holders of the requisite principal amount of outstanding debt securities have given any request, demand, authorization, direction, notice, consent or waiver under the applicable indenture or are present at a meeting of holders of debt securities for quorum purposes:

• in the case of any debt security that by its terms provides for declaration of a principal amount less than the principal face amount of the debt security to be due and payable upon acceleration, the principal amount that will be deemed outstanding will be the principal amount that would be declared to be due and payable upon a declaration of acceleration thereof at the time of such determination;

• in the case of any indexed security, the principal amount that will be deemed outstanding will be the principal face amount of the indexed security at original issuance;

• in the case of any debt security denominated in one or more foreign currency units, the principal amount that will be deemed outstanding will be the U.S. dollar equivalent based on the applicable exchange rate or rates at the time of sale; and

• any debt securities owned by us or any other obligor upon the debt securities or any of our or such other obligor’s affiliates, will be disregarded and deemed not outstanding.

Governing Law

The indentures and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

Regarding the Indenture Trustees

In the normal course of business, we and our subsidiaries may conduct banking transactions with the indenture trustees, and the indenture trustees may conduct banking transactions with us and our subsidiaries.

Subscription rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the subscription rights. In connection with any subscription rights offering to our shareholders, subject to compliance with applicable law, we may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such subscription rights offering. Each series of subscription rights will be issued under a separate subscription rights agent agreement to be entered into between us and a bank or trust company, as subscription rights agent, that we will name in the applicable prospectus supplement. Unless we indicate otherwise in the applicable prospectus supplement, the subscription rights agent will act solely as our agent in connection with the certificates relating to the subscription rights and will not assume any obligation or relationship of agency or trust for or with any holders of subscription rights certificates or beneficial owners of subscription rights.

Subscription rights may be exercised at any time up to the close of business on the expiration date (subject to any extension) for the subscription rights provided in the applicable prospectus supplement. After the close of business on the expiration date (subject to any extension), all unexercised subscription rights will become void and of no further force or effect.

Holders may exercise subscription rights as described in the applicable prospectus supplement. Upon receipt of payment and the subscription rights certificate properly completed and duly executed at the corporate trust office of the subscription rights agent or any other office indicated in the prospectus supplement, we will, as soon as practicable, issue the shares of Class A common stock or other security purchasable upon exercise of the subscription rights. Subject to compliance with applicable law, if less than all of the subscription rights issued in any subscription rights offering are exercised, we may offer any unsubscribed securities directly to persons other than shareholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

IMPORTANT PROVISIONS OF VIRGINIA LAW AND OUR ARTICLES OF

INCORPORATION, BYLAWS AND SHAREHOLDER RIGHTS AGREEMENT

The following description of certain provisions of Virginia law and our articles of incorporation, bylaws and the Rights Agreement is only a summary. For a complete description, we refer you to Virginia law, our articles of incorporation, bylaws and the Rights Agreement. We have filed our articles of incorporation, bylaws and the Rights Agreement as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information.”

General

Our articles of incorporation, bylaws, the Rights Agreement and the Virginia Stock Corporation Act contain certain provisions that could delay or impede transactions involving an actual or potential change of control of our company, limit the ability of shareholders to remove directors or management or approve a transaction they deem to be in their best interest or adversely affect the price of our securities.

Number of Directors; Removal; Filling Vacancies

Our articles of incorporation and bylaws provide that there shall be seven Directors. By amendment of our bylaws, the Board of Directors or the shareholders may increase or decrease the number of Directors in accordance with applicable law. A decrease in the number of Directors shall not shorten the term of any incumbent Director. Directors hold office until their death, resignation or removal or until their successor is elected.

At any time, the Board of Directors may remove any Director with cause by the affirmative vote of all members of the Board of Directors, excluding the Director subject to removal, and may elect a successor to fill any resulting vacancy for the balance of the removed Director’s term. With the exception of Directors elected by the holders of outstanding shares of preferred stock as a separate voting group, any Director may be removed from office with or without cause by the affirmative vote of the holders of at least two-thirds of the voting power of all outstanding shares of our company entitled to vote generally in the election of Directors.

Our bylaws provide that vacancies on the Board of Directors, including a vacancy resulting from death, resignation, disqualification or removal or an increase in the number of Directors, shall be filled by the Board of Directors, the shareholders or the affirmative vote of a majority of the remaining Directors where less than a quorum of the Board of Directors remains. Where a resignation will become effective at a specified later date, it

20

may be filled before the vacancy occurs, but the new Director may not take office until the vacancy occurs. A Director elected by the Board of Directors to fill a vacancy shall be elected to hold office until the next annual meeting of shareholders or until his or her successor is elected.

Shareholder Action

Our articles of incorporation and bylaws provide that special meetings of the shareholders may only be called by the Board of Directors pursuant to a resolution stating the purpose or purposes thereof approved by a majority of the Directors, the chairman, vice-chairman, chief executive officer or the president of the company. Only the business falling within the purpose or purposes described in the notice shall be conducted at a special meeting.

Advance Notice for Shareholder Proposals or Nominations at Meetings

Our bylaws establish advance notice procedures for shareholder proposals regarding business or nominations to be brought before any annual or special meeting of shareholders. Except for the election of Directors by the unanimous written consent of shareholders or the filling of vacancies on the Board of Directors by the Board Directors, only persons nominated in accordance with the notice procedures set forth in our bylaws shall be eligible to serve as a Director. Similarly, other business shall not be conducted at a meeting of shareholders unless it is brought before the meeting in accordance with the procedures set forth in our bylaws. Except as otherwise dictated by law, the chairman of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was properly made or proposed, as the case may be. If any nomination or business is defectively made or proposed, it shall be disregarded.

Annual Meetings

Nominations of persons for election to the Board of Directors and the proposal of business to be considered by the shareholders may be made at the annual meeting of shareholders in the following ways. Such nominations or proposals may be made pursuant to a notice of the meeting, by or at the direction of the Board of Directors or by a shareholder of our company who is a shareholder of record of a class of shares entitled to voted on the business such shareholder is proposing, both on the record date for the annual meeting and at the giving of the shareholder’s notice, and who complies with the notice procedures provided for in our bylaws.

To properly bring nominations or other business before an annual meeting of the shareholders, a shareholder must give timely, written notice thereof, and the proposed business must be proper for shareholder consideration. To be timely, the notice must be delivered to the secretary of our company at our company’s principal executive officers not later than the close of business on the 90^th day nor earlier that the close of business on the 120^th day prior to the first anniversary of the preceding year’s annual meeting. However, if the annual meeting is more than 30 days before or more than 60 days after such anniversary, the shareholder’s notice must be delivered to the secretary of our company at our company’s principal executive offices not earlier that the close of business on the 120^th day prior to the annual meeting and not later than the close of business on the later of the 90^th day prior to the annual meeting or the tenth day following the date on which we first make public announcement of the date of our annual meeting.

The shareholder’s notice must contain certain information. As to each person the shareholder proposes to nominate for election or re-election to the Board of Directors, the notice must contain all information relating to such person that is required to be disclosed in solicitations of proxies for election of Directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act and Rule 14a-8 thereunder. As to any other business that the shareholder proposes to bring before the meeting, the notice must contain a brief description of the proposed business and any material interest in such business of the shareholder and the beneficial owner, if any, on whose behalf the proposal is made. The shareholder notice must also provide the name and address of the shareholder and the beneficial owner, if any, on whose behalf the

21

proposal is made as they appear on the books of the corporation as well as the class and number of shares that are owned beneficially and of record by such shareholder and such beneficial owner, as the case may be.

If the number of Directors to be elected to the Board of Directors is increased and there is no public announcement by us naming all of the nominees for Director or specifying the size of the increased Board of Directors at least 100 days prior to the first anniversary of the preceding year’s annual meeting, a shareholder’s notice will be considered timely, but only with respect to nominees for any new positions created by the increase, if it is delivered to the secretary of the company at our principal executive offices not later than the close of business on the tenth day following the date on which we first make such public announcement.

Special Meetings

Nominations of persons for election to the Board of Directors may be made at a special meeting of shareholders at which Directors are to be elected pursuant to the notice of meeting in two ways. Such nominations may be made by or at the direction of the Board of Directors. Additionally, a nomination may be made by any shareholder who was a shareholder of record at the time notice of the meeting was given, who shall be entitled to vote at the meeting and who complies with the notice procedures set forth in our bylaws. Any shareholder so qualified may nominate a person or persons for election to the position or positions specified in the notice of meeting if the shareholder provides timely, written notice thereof to the secretary of the company at our principal executive offices. To be timely, such notice must be provided not earlier that the close of business on the 120^th day prior to the special meeting and not later than the close of business on the later of the 90^th day prior to the special meeting or the tenth day following the day on which public announcement of the date of the special meeting and of the nominees proposed by the Board of Directors to be elected at such meeting is first made.

Amendment of the Bylaws

Our bylaws may be amended or repealed, and new bylaws may be made, at any regular or special meeting of the Board of Directors. Bylaws made by the Board of Directors may be repealed or changed and new bylaws may be made by the shareholders, and the shareholders may prescribe that any bylaw made by them shall not be altered, amended or repealed by the Board of Directors. The affirmative vote of at least 80% of the voting power of the outstanding shares of our capital stock entitled to vote is required for the shareholders to adopt, alter or repeal any bylaw that requires or would require the company to hold, or sets forth procedures for the holding of, a special meeting of shareholders or that governs or would govern the nomination of persons for election to the Board of Directors or the proposal of business to be considered at an annual or special meeting of shareholders.

Amendment of the Articles of Incorporation

For every voting group entitled to vote on a proposed amendment to our articles of incorporation, the vote required for approval shall be either the vote specifically required by our articles of incorporation or, if no voting requirement is specified, a majority of the votes entitled to be cast.

Except for amendments to our articles of incorporation adopted by the Board of Directors that establish any series of preferred stock, the affirmative vote of at least 80% of the voting power of the outstanding shares of the company is required to amend our articles of incorporation to include two types of provisions. The provisions that require such a vote are those that would require the company to hold, or set forth procedures for the holding of, a special meeting of shareholders or that would govern the nomination of persons for election to the Board of Directors of the proposal of business to be considered at an annual or special meeting of shareholders. The affirmative vote of at least 80% of the voting power of the outstanding shares of the company is also required to alter, amend or adopt any provision inconsistent with or repealing the Article VIII of our articles of incorporation, which addresses certain voting matters including the amendment of our bylaws and articles of incorporation.

Common Stock

Our articles of incorporation grant us the authority to issue 450,000,000 shares of Class A common stock and 100,000,000 shares of Class B common stock. Our articles of incorporation contain certain provisions that give holders of our Class B common stock greater voting rights than those of holders of our Class A common stock. Except where otherwise provided by law, shares of Class A common stock are entitled to one vote on all matters on which the shareholders are entitled to vote, and shares of Class B common stock are entitled to three votes on all such matters. The holders of Class A and Class B common stock vote together as a single voting group. Therefore, holders of our Class B common stock may exert significant influence on the outcome of all corporate actions requiring shareholder approval.

To the exclusion of the holders of any other class of shares, the holders of the outstanding shares of common stock have the sole power to vote for the election of Directors and for all other purposes without limitation, except as required by law.

Preferred Stock

Our articles of incorporation grant us the authority to issue 25,000,000 shares of preferred stock and authorize the Board of Directors, by the adoption of amendments to our articles of incorporation, to issue preferred stock in one or more series and to provide for the designation, preferences, limitations and relative rights of the shares of each series.

The availability of the preferred stock provides us with increased flexibility in structuring possible future financings and acquisitions and in meeting other corporate needs that might arise. Having the authorized shares available for issuance allows us to issue shares of preferred stock without the expense and delay of a special meeting of the shareholders. The authorized shares of preferred stock, as well as shares of common stock, will be available for issuance without further action by our shareholders, unless that action is required by applicable law or the rules of any stock exchange on which our securities are listed. Our Board of Directors has the power, subject to applicable law, to issue a series of preferred stock that could, depending on the terms of the series, impede the completion of a merger, tender offer, or other takeover attempt. For example, in connection with the Board of Director’s adoption of our Rights Agreement, our Board of Directors designated Series A junior preferred stock, par value $0.01 per share. See “Shareholder Rights Agreement.”

Virginia Law

The Virginia Stock Corporation Act contains provisions that may have the effect of impeding the acquisition of control of a Virginia corporation by means of a tender offer, proxy contest, open market purchases or otherwise in a transaction not approved by the company’s Board of Directors. These provisions are designed to reduce the corporation’s vulnerability to coercive takeover practices and inadequate takeover bids.

Affiliated Transactions Statute

We are subject to the “affiliated transactions” provisions of the Virginia Stock Corporation Act, which restrict certain transactions between us and any person, or an Interested Shareholder, who beneficially owns more than 10% of any class of our voting securities, or Affiliated Transactions. These restrictions do not apply to an Affiliated Transaction with an Interested Shareholder who has continuously been an Interested Shareholder since the date we first had 300 shareholders of record or whose acquisition of shares making him an Interested Shareholder was previously approved by a majority of our disinterested directors. “Disinterested Director” means, with respect to a particular Interested Shareholder, a member of our Board of Directors who was a member on the date on which an Interested Shareholder became an Interested Shareholder or recommended for election by, or was elected to fill a vacancy and received the affirmative vote of, a majority of the Disinterested Directors then on the Board of Directors.

23

Affiliated Transactions include mergers, share exchanges, material dispositions of corporate assets not in the ordinary course of business, any dissolution of our company proposed by or on behalf of an Interested Shareholder, or any reclassification, including reverse stock splits, recapitalization or merger of our company with its subsidiaries, which increases the percentage of voting shares owned beneficially by an Interested Shareholder by more than five percent.

The “affiliated transactions” provisions prohibit us from engaging in an Affiliated Transaction with an Interested Shareholder for a period of three years after the Interested Shareholder became such unless the transaction is approved by the affirmative vote of a majority of the Disinterested Directors and by the affirmative vote of the holders of two-thirds of the voting shares other than those shares beneficially owned by the Interested Shareholder. Following the three-year period, in addition to any other vote required by law or our articles of incorporation, an Affiliated Transaction must be approved either by a majority of the Disinterested Directors or by the shareholder vote described in the preceding sentence unless the transaction satisfies the fair-price provisions of the statute. These fair-price provisions require, in general, that the consideration to be received by shareholders in the Affiliated Transaction be in cash or in the form of consideration used by the Interested Shareholder to acquire the largest number of its shares and not be less, on a per share basis, than an amount determined in the manner specified in the statute by reference to the highest price paid by the Interested Shareholder for shares it acquired and the fair market value of the shares on specified dates.

Control Share Acquisitions Statute

Pursuant to our bylaws, the provisions of Article 14.1 of the Virginia Stock Corporation Act relating to “control share acquisitions” shall not apply to the corporation.

Shareholder Rights Agreement

On June 1, 2009, our Board of Directors adopted the Shareholder Rights Agreement, and declared a dividend of one preferred share purchase right, each, a Right, for each outstanding share of our Class A common stock and Class B common stock. No shareholder approval was required for adoption of the Shareholder Rights Agreement, however, our shareholders approved the Shareholder Rights Agreement at our annual meeting on June 2, 2010.

Our Board of Directors adopted the Shareholder Rights Agreement in an effort to protect against a possible limitation on our ability to use our net operating loss carry forwards, or NOLs, net capital loss carry forwards, or NCLs, and built-in losses under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, or the Code. Our ability to use our NOLs, NCLs and built-in losses would be limited if we experienced an “ownership change” under Section 382 of the Code. The Shareholder Rights Agreement was adopted to dissuade any person or group from acquiring 4.9% or more of our outstanding Class A common stock, each, an Acquiring Person, without the approval of the Board of Directors and triggering an “ownership change” as defined by Section 382.

Initially, the Rights generally will not be exercisable and will be attached to and automatically trade with our Class A common stock and Class B common stock. The Rights will separate from the Class A common stock and Class B common stock and a “distribution date” will occur, with certain exceptions and upon a determination of our Board of Directors, upon the earlier of:

• 10 business days after a public announcement by us that a person or group has become an Acquiring Person; or

• 10 business days after the commencement of a tender or exchange offer by a person or group for 4.9% or more of the Class A common stock.

Shareholders who owned 4.9% or more of our outstanding Class A common stock at the time of adoption of the Shareholder Rights Agreement will not trigger the Shareholder Rights Agreement so long as they do not

24

(i) acquire any additional shares of Class A common stock or (ii) fall under 4.9% ownership of Class A common stock and then re-acquire additional shares so that they own 4.9% or more of the Class A common stock.

Subject to the terms, provisions and conditions of the Shareholder Rights Agreement, and taking into account our 1-for-20 reverse stock split that was effected on October 6, 2009, if the Rights become exercisable, each Right would represent the right to purchase from us one ten-thousandth of a share of Series A junior preferred stock for a purchase price of $3.00 each, subject to adjustment in accordance with the terms of the Shareholder Rights Agreement. Each post-split share of our Class A and Class B common stock is now associated with, and now trades with, 20 Rights. If issued, each 20 fractional shares of preferred stock would give the shareholder approximately the same dividend, voting and liquidation rights as does one share of the our Class A common stock. However, prior to exercise, a Right does not give its holder any rights as a shareholder of our company, including without limitation any dividend, voting or liquidation rights.

After the Distribution Date and following a determination by the Board of Directors that a person is an Acquiring Person, each holder of a Right, other than Rights beneficially owned by the Acquiring Person (which will thereupon become void), will thereafter have the right to receive upon exercise of a Right and payment of the purchase price, that number of shares of Class A common stock or Class B common stock, as the case may be, having a market value of two times the purchase price of the Right.

After the Distribution Date and following a determination by the Board of Directors that a person is an Acquiring Person, the Board may exchange the Rights (other than Rights owned by such person or group which will have become void), in whole or in part, at an appropriate exchange ratio of shares of Class A common stock or Class B common stock, as the case may be, or a fractional share of Series A Preferred Stock (or of a share of a similar class or series of the Company’s preferred stock having similar Rights, preferences and privileges) of equivalent value, per Right (subject to adjustment).

Each share of Series A junior preferred stock, if issued and outstanding:

• will not be redeemable;

• will entitle holders of record to (i) cumulative quarterly cash dividends when, as and if declared by our Board of Directors in an amount equal to $0.01 per whole share, less the amount of all cash dividends declared on the Series A junior preferred stock pursuant the following clause (ii) since the immediately preceding dividend payment date or, with respect to the first dividend payment date, since the fist issuance of any share of Series A junior preferred stock and (ii) dividends payable in cash on the dividends payment for each cash dividend declared on the Class A or Class B common stock in an amount per whole share equal to a formula number (which unless adjusted equals 10,000), or the Formula Number, then in effect multiplied by the cash dividends then to be paid on each share of Class A or Class B common stock. In addition, if we pay any dividend on the Class A or Class B common stock payable in assets, securities or other forms of non-cash consideration (other than solely in shares of Class A or Class B common stock), then, in each case, we shall pay on each outstanding whole share of Series A junior preferred stock a dividend in like kind equal to the Formula Number then in effect;

• will generally entitle the holder to a number of votes equal to the Formula Number then in effect on all matters submitted to a vote of the holders of Class A and Class B common stock and will have the right to vote as a single class with respect to such matters as a required by law;

• will entitle holders upon liquidation to receive an amount equal to any accrued and unpaid dividends and distributions on Series A junior preferred shares, whether or not declared, plus an amount equal to the greater of (i) $0.01 per whole Series A junior preferred share and (ii) an aggregate amount per whole Series A junior preferred share equal to the Formula Number then in effect times the aggregate amount to be distributed to per share to holders of Class A and Class B common stock; and

25

• if shares of our Class A and Class B common stock are exchanged via merger, consolidation, or a similar transaction, will entitle holders to a per share payment equal to the Formula Number then in effect times the aggregate amount of stock, securities, cash and other property, in which or for which each share of common stock is changed or exchanged.

The Board may adjust the purchase price of the preferred shares, the number of preferred shares issuable and the number of outstanding Rights to prevent dilution that may occur as a result of certain events, including among others, a stock dividend, a forward or reverse stock split or a reclassification of the preferred shares or Class A common stock or Class B common stock. No adjustments to the purchase price of less than 1% will be made.

The Rights will have certain anti-takeover effects. The Rights will cause substantial dilution to any person or group that attempts to acquire the corporation without the approval of the Board of Directors. As a result, the overall effect of the Rights may be to render more difficult or discourage any attempt to acquire the corporation even if such acquisition may be favorable to the interests of the corporation’s shareholders. Because the Board of Directors can redeem the Rights, the Rights should not interfere with a merger or other business combination approved by the Board of Directors.

Before the Distribution Date, the Board of Directors may amend or supplement the Rights Agreement without the consent of the holders of the Rights. After the Distribution Date, the Board of Directors may amend or supplement the Rights Agreement only to cure an ambiguity, to alter time period provisions, to correct inconsistent provisions, or to make any additional changes to the Rights Agreement, but only to the extent that those changes do not impair or adversely affect, in any material respect, any Rights holder and do not result in the Rights again becoming redeemable, and no such amendment may cause the Rights again to become redeemable or cause this Rights Agreement again to become amendable other than in accordance with the applicable timing of the Rights Agreement.

The Rights and the Shareholder Rights Agreement will expire on the earliest of (i) June 4, 2019, (ii) the time at which the Rights are redeemed pursuant to the Shareholder Rights Agreement, (iii) the time at which the Rights are exchanged pursuant to the Shareholder Rights Agreement, (iv) the repeal of Sections 382 and 383 of the Code or any successor statute if the Board of Directors determines that the Shareholder Rights Agreement is no longer necessary for the preservation of the applicable tax benefits and (v) the beginning of a taxable year to which the Board of Directors determines that no applicable tax benefits may be carried forward.

The Certificate of Designations of our Series A junior preferred stock and the Rights Agreement are filed as exhibits to the registration statement to which this prospectus forms a part and are incorporated herein by reference. The foregoing description of the Rights is qualified in its entirety by reference to the Rights Agreement.

Virginia Law

The Virginia Stock Corporation Act contains provisions that may have the effect of impeding the acquisition of control of a Virginia corporation by means of a tender offer, proxy contest, open market purchases or otherwise in a transaction not approved by the corporation’s Board of Directors. These provisions are designed to reduce the corporation’s vulnerability to coercive takeover practices and inadequate takeover bids.

Affiliated Transactions Statute

We are subject to the “affiliated transactions” provisions of the Virginia Stock Corporation Act, which restrict certain transactions between us and any person, or an Interested Shareholder, who beneficially owns more than 10% of any class of our voting securities, or Affiliated Transactions. These restrictions do not apply to an Affiliated Transaction with an Interested Shareholder who has continuously been an Interested Shareholder since the date we first had 300 shareholders of record or whose acquisition of shares making him an Interested

26

Shareholder was previously approved by a majority of our disinterested directors. “Disinterested Director” means, with respect to a particular Interested Shareholder, a member of our Board of Directors who was a member on the date on which an Interested Shareholder became an Interested Shareholder or recommended for election by, or was elected to fill a vacancy and received the affirmative vote of, a majority of the Disinterested Directors then on the Board of Directors.

Affiliated Transactions include mergers, share exchanges, material dispositions of corporate assets not in the ordinary course of business, any dissolution of our company proposed by or on behalf of an Interested Shareholder, or any reclassification, including reverse stock splits, recapitalization or merger of our company with its subsidiaries, which increases the percentage of voting shares owned beneficially by an Interested Shareholder by more than five percent.

The “affiliated transactions” provisions prohibit us from engaging in an Affiliated Transaction with an Interested Shareholder for a period of three years after the Interested Shareholder became such unless the transaction is approved by the affirmative vote of a majority of the Disinterested Directors and by the affirmative vote of the holders of two-thirds of the voting shares other than those shares beneficially owned by the Interested Shareholder. Following the three-year period, in addition to any other vote required by law or our articles of incorporation, an Affiliated Transaction must be approved either by a majority of the Disinterested Directors or by the shareholder vote described in the preceding sentence unless the transaction satisfies the fair-price provisions of the statute. These fair-price provisions require, in general, that the consideration to be received by shareholders in the Affiliated Transaction be in cash or in the form of consideration used by the Interested Shareholder to acquire the largest number of its shares and not be less, on a per share basis, than an amount determined in the manner specified in the statute by reference to the highest price paid by the Interested Shareholder for shares it acquired and the fair market value of the shares on specified dates.

Control Share Acquisitions Statute

Pursuant to our bylaws, the provisions of Article 14.1 of the Virginia Stock Corporation Act relating to “control share acquisitions” shall not apply to our company.

BOOK-ENTRY PROCEDURES AND SETTLEMENT

We can issue the securities covered by this prospectus in definitive form or in the form of one or more global securities. The applicable prospectus supplement will describe the manner in which the securities offered thereby will be issued.

PLAN OF DISTRIBUTION

We may use this prospectus and any accompanying prospectus supplement to sell our securities from time to time as follows:

• directly to purchasers;

• through underwriters;

• through dealers;

• through agents;

• through any combination of these methods; or

• through any other method permitted by applicable law and described in a prospectus supplement.

27

Each prospectus supplement relating to an offering of securities will set forth the specific plan of distribution and state the terms of the offering, including:

• The method of distribution of the securities offered therein;

• The names of any underwriters, dealers, or agents;

• The public offering or purchase price of the offered securities and the net proceeds that we will receive from the sale;

• Any underwriting discounts, commissions or other items constituting underwriters’ compensation;

• Any discounts, commissions, or fees allowed, re-allowed or paid to dealers or agents; and

• Any securities exchange on which the offered securities may be listed.

Any public offering price and any discounts, commissions, fees or concessions allowed or reallowed or paid to underwriters, dealers, or agents may be changed from time to time.

Distribution Through Underwriters

We may offer and sell securities from time to time to one or more underwriters who would purchase the securities as principal for resale to the public, either on a firm commitment or best efforts basis. If we sell securities to underwriters, we will execute an underwriting agreement with them at the time of the sale and will name them in the applicable supplement. In connection with these sales, the underwriters may be deemed to have received compensation from us in the form of underwriting discounts and commissions. The underwriters also may receive commissions from purchasers of securities for whom they may act as agent. Unless we specify otherwise in the applicable supplement, the underwriters will not be obligated to purchase the securities unless the conditions set forth in the underwriting agreement are satisfied, and if the underwriters purchase any of the securities, they generally will be required to purchase all of the offered securities. The underwriters may acquire the securities for their own account and may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or varying prices determined at the time of sale. The underwriters may sell the offered securities to or through dealers, and those dealers may receive discounts, concessions, or commissions from the underwriters as well as from the purchasers for whom they may act as agent.

Distribution Through Dealers

We may offer and sell securities from time to time to one or more dealers who would purchase the securities as principal. The dealers then may resell the offered securities to the public at fixed or varying prices to be determined by those dealers at the time of resale. We will set forth the names of the dealers and the terms of the transaction in the applicable supplement.

Distribution Through Agents

We may offer and sell securities on a continuous basis through agents that become parties to an underwriting or distribution agreement. We will name any agent involved in the offer and sale, and describe any commissions payable by us in the applicable supplement. Unless we specify otherwise in the applicable supplement, the agent will be acting on a best efforts basis during the appointment period. The agent may make sales in privately negotiated transactions and by any other method permitted by law, including sales deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act, including sales made directly on the NYSE, or sales made to or through a market maker other than on an exchange.

Direct Sales

We may sell directly to, and solicit offers from, institutional investors or others who may be deemed to be underwriters, as defined in the Securities Act, for any resale of the securities. We will describe the terms of any sales of this kind in the applicable supplement.

28

General Information

Underwriters, dealers, or agents participating in an offering of securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the offered securities, may be deemed to be underwriting discounts and commissions under the Securities Act.

We may offer to sell securities either at a fixed price or at prices that may vary, at market prices prevailing at the time of sale, at prices related to prevailing market prices, or at negotiated prices. Securities may be sold in connection with a remarketing after their purchase by one or more firms acting as principal for their own accounts or as our agent. In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders.

In connection with an underwritten offering of the securities, the underwriters may engage in over-allotment, stabilizing transactions and syndicate covering transactions in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which creates a short position for the underwriters. The underwriters may enter bids for, and purchase, securities in the open market in order to stabilize the price of the securities. Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover short positions. In addition, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions, or otherwise. These activities may cause the price of the securities to be higher than it would otherwise be. Those activities, if commenced, may be discontinued at any time.

Ordinarily, each issue of securities will be a new issue, and there will be no established trading market for any security other than our common stock, which is listed on the New York Stock Exchange under the symbol “AI”, prior to its original issue date. We may not list any particular series of securities on a securities exchange or quotation system. Any underwriters to whom or agents through whom the offered securities are sold for offering and sale may make a market in the offered securities. However, any underwriters or agents that make a market will not be obligated to do so and may stop doing so at any time without notice. We cannot assure you that there will be a liquid trading market for the offered securities.

We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the related prospectus supplement, and the related prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

We may offer subscription rights to our existing shareholders to purchase additional shares of our Class A common stock, preferred stock or other securities and any combination thereof. For any particular subscription rights, the applicable prospectus supplement will describe the terms of such rights, including the period during which such rights may be exercised, the manner of exercising such rights, the transferability of such rights and the number of shares of Class A common stock, preferred stock or other securities that may be purchased in connection with each right and the subscription price for the purchase of such securities. In connection with a rights offering, we may enter into a separate agreement with one or more underwriters or standby purchasers to purchase any securities not subscribed for in the rights offering by existing shareholders. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. Additionally, prior to the expiration date of any such subscription rights, any standby underwriters in a subscription rights offering to our shareholders may offer such securities on a when-issued basis, including securities to be acquired through the purchase and exercise of subscription rights, at prices set from time to time by the standby underwriters. After the expiration date of any such subscription rights, the underwriters may offer securities of the type underlying the subscription rights, whether acquired pursuant to a standby underwriting agreement, the exercise of the subscription rights or the purchase of such securities in the market, to the public at

29

a price or prices to be determined by the underwriters. The standby underwriters may thus realize profits or losses independent of the underwriting discounts or commissions paid by us. If we do not enter into a standby underwriting arrangement in connection with a subscription rights offering to our shareholders, we may elect to retain a dealer-manager to manage the subscription rights offering for us. Any dealer-manager may offer securities of the type underlying the subscription rights acquired or to be acquired pursuant to the purchase and exercise of subscription rights and may thus realize profits or losses independent of any dealer-manager fee paid by us.

Under agreements entered into with us, underwriters and agents may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act of 1933, or to contribution for payments the underwriters or agents may be required to make.

The maximum commission or discount to be received by any member of the Financial Industry Regulatory Authority, Inc. or independent broker-dealer will not be greater than 8% of the initial gross proceeds from the sale of any security being sold.

Although we expect that delivery of securities generally will be made against payment on or about the third business day following the date of any contract for sale, we may specify a longer settlement cycle in the applicable supplement. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to a trade expressly agree otherwise. Accordingly, if we have specified a longer settlement cycle in the applicable supplement for an offering of securities, purchasers who wish to trade those securities on the date of the contract for sale, or on one or more of the next succeeding business days as we will specify in the applicable supplement, will be required, by virtue of the fact that those securities will settle in more than T+3, to specify an alternative settlement cycle at the time of the trade to prevent a failed settlement and should consult their own advisors in connection with that election.

The validity of securities covered by this prospectus has been passed upon for us by Hunton & Williams LLP. Any underwriters, dealers or agents will be advised by their own legal counsel concerning issues related to the offering of securities pursuant to this prospectus.
