The Asset-Based Credit Facility matures on November 1, 2016 and is secured by inventory at certain of our domestic manufacturing plants, our domestic service parts inventory as well as our domestic used truck inventory. All borrowings under the Asset-Based Credit Facility will accrue interest at a rate equal to a Base Rate or an adjusted London Interbank Offered Rate (“LIBOR”) plus a spread. The spread, which will be based on an availability-based measure, ranges from 50 basis points to 100 basis points for Base Rate borrowings and from 150 basis points to 200 basis points for LIBOR borrowings. The initial LIBOR spread is 175 basis points. Borrowings under the Asset-Based Credit Facility are available for general corporate purposes. The LIBOR spread as of October 31, 2011 was 175 basis points. As of October 31, 2011, we had no borrowings under the Asset-Based Credit Facility. There were no defaults or Events of Default incurred under the loan agreement as we were, and continue to be, in compliance with all the covenants contained in the definitive loan agreement. On November 4, 2011, we borrowed $100 million under the Asset-Based Credit Facility to redeem a portion of our 8.25% Senior Notes, due in 2021.In September 2011, Navistar, Inc. entered into a $40 million floating rate promissory note with Caterpillar (the "Promissory Note"), under which the principal amount will be repaid over a 4 year term in 16 quarterly installments. The floating interest rate for the Promissory Note will be computed based on LIBOR plus 2.75% over the term of the note. For more information please refer to Note 3, Acquisitions and disposals of businesses. In October 2010, we benefited from certain tax-exempt bond financings in which (i) the Illinois Finance Authority issued and sold $135 million aggregate principal amount of Recovery Zone Facility Revenue Bonds due October 15, 2040 and (ii) The County of Cook, Illinois issued and sold $90 million aggregate principal amount of Recovery Zone Facility Revenue Bonds also due October 15, 2040 (collectively the “Tax Exempt Bonds”). The Tax Exempt Bonds were issued pursuant to separate, but substantially identical, indentures of trust dated as of October 1, 2010. The proceeds of the Tax Exempt Bonds were loaned by each issuer to the Company pursuant to separate, but substantially identical, loan agreements dated as of October 1, 2010. The proceeds from the issuance of the Tax Exempt Bonds are restricted, and must be used substantially for capital expenditures related to financing the relocation of the Company's headquarters, the expansion of an existing warehouse facility, and the development of certain industrial and testing facilities, together with related improvements and equipment (the “Projects”). The payment of principal and interest on the Tax Exempt Bonds are guaranteed under separate, but substantially identical, bond guarantees issued by Navistar, Inc. The Tax Exempt Bonds are special, limited obligations of each issuer, payable out of the revenues and income derived under the related loan agreements and related guarantees. The Tax Exempt Bonds bear interest at the fixed rate of 6.5% per annum, payable each April 15 and October 15, commencing April 15, 2011. Beginning on October 15, 2020, the Tax Exempt Bonds are subject to optional redemption at the direction of the Company, in whole or in part, at the redemption price equal to 100% of the principal amount thereof, plus accrued interest, if any, to the redemption date. The funds received from the issuance of the Tax Exempt Bonds were deposited directly into trust accounts by the bonding authority at the time of issuance, and will be remitted to the Company on a reimbursement basis as we make qualified capital expenditures related to the Projects. As the Company does not have the ability to use these funds for general operating purposes, they are classified as Other noncurrent assets in our Consolidated Balance Sheets. In addition, as the Company did not receive cash proceeds upon the closing of the Tax Exempt Bonds, there was no impact on the Consolidated Statement of Cash Flows for the year ended October 31, 2010. As the Company makes qualifying capital expenditures and is reimbursed by the Trust, the Company reports the corresponding amounts as capital expenditures and proceeds from issuance of debt within the Consolidated Statement of Cash Flows. In November 2010, we finalized the purchase of the property and buildings that we are developing into our new world headquarters site. As of October 31, 2011, reimbursement was received for $91 million of the $225 million under the Tax Exempt Bonds. In October 2009, we completed the sale of $1.0 billion aggregate principal amount of our 8.25% Senior Notes due 2021 (the “Senior Notes”). Interest is payable on May 1 and November 1 of each year until the maturity date of November 1, 2021. The Company received net proceeds of approximately $947 million, net of offering discount of $37 million and underwriter fees of $16 million. The discount and debt issue costs are being amortized to Interest expense over the life of the Senior Notes for an effective rate of 8.96%, and the debt issue costs are recorded in Other noncurrent assets. The proceeds, in conjunction with the proceeds of the concurrent 3.0% Senior Subordinated Convertible Notes due 2014 (the “Convertible Notes”) discussed below, were used to repay all amounts outstanding under the prior $1.5 billion5-year term loan facility and synthetic revolving facility, as well as certain fees incurred in connection therewith. The Senior Notes are senior unsecured obligations of the Company. The Senior Notes contain an optional redemption feature allowing the Company at any time prior to November 1, 2012 to redeem up to 35% of the aggregate principal amount of the notes using proceeds of certain public equity offerings at a redemption price of 108.25% of the principal amount of the notes, plus accrued and unpaid interest, if any. On or after November 1, 2014, the Company can redeem all or part of the Senior Notes during the twelve-month period beginning on November 1, 2014, 2015, 2016, 2017, and thereafter at a redemption price equal to 104.125%, 102.750%, 101.375%, and 100%, respectively, of the principal amount of the notes redeemed. In addition, not more than once during each twelve-month period ending on November 1, 2010, 2011, 2012, 2013, and 2014, the Company may redeem up to $50 million in principal amount of the notes in each such twelve-month period, at a redemption price equal to 103% of the principal amount of the notes redeemed, plus accrued and unpaid interest, if any. The Company exercised this early redemption feature for $100 million in total principal by redeeming $50 million on November 1, 2011 and $50 million on November 2, 2011. The Company may also redeem the Senior Notes at its election in whole or part at any time prior to November 1, 2014 at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium, plus accrued and unpaid interest, to the redemption date. The Applicable Premium is defined as the greater of: 1% of the principal amount and the excess, if any, of (i) the present value as of such date of redemption of (A) the redemption price of such note on November 1, 2014, plus (B) all required interest payments due on such note through November 1, 2014, computed using a discount rate equal to the Treasury Rate (as defined in the debt agreement), plus 50 basis points over (ii) the then-outstanding principal of such note. In October 2009, we also completed the sale of $570 million aggregate principal amount of our Convertible Notes, including over-allotment options. Interest is payable on April 15 and October 15 of each year until the maturity date of October 15, 2014. The Company received net proceeds of approximately $553 million, net of $17 million of underwriter fees. The debt issue costs are recorded in Other noncurrent assets and are being amortized to Interest expense over the life of the Convertible Notes. The Convertible Notes are senior subordinated unsecured obligations of the Company. Holders may convert the Convertible Notes into common stock of the Company at any time on or after April 15, 2014. Holders may also convert the Convertible Notes at their option prior to April 15, 2014, under the following circumstances: (i) during any fiscal quarter commencing after January 31, 2010, if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each such trading day; (ii) during the five business day period after any five consecutive trading day period (the “Measurement Period”) in which the trading price per $1,000 principal amount of notes for each trading day of that Measurement Period was less than 98% of the product of the last reported sale price of the common stock and the applicable conversion rate on each such trading day; or (iii) upon the occurrence of specified corporate events, as more fully described in the Convertible Notes Indenture. The conversion rate will initially be 19.8910 shares of common stock per $1,000 principal amount of Convertible Notes (equivalent to an initial conversion price of approximately $50.27 per share of common stock). The conversion rate may be adjusted for anti-dilution provisions and the conversion price may be decreased by the Board of Directors to the extent permitted by law and listing requirements. The Convertible Notes can be settled in common stock, cash, or a combination of common stock and cash. Upon conversion, the Company will satisfy its conversion obligations by delivering, at its election, shares of common stock (plus cash in lieu of fractional shares), cash, or any combination of cash and shares of common stock. If the Company elects to settle in cash or a combination of cash and shares, the amounts due upon conversion will be based on a daily conversion value calculated on a proportionate basis for each trading day in a 40 trading-day observation period. If a holder converts its Convertible Notes on or after April 15, 2014, and the Company elects physical settlement as described above, the holder will not receive the shares of common stock into which the Convertible Notes are convertible until after the expiration of the observation period described above, even though the number of shares the holder will receive upon settlement will not change. It is our policy to settle the principal and accrued interest on the Convertible Notes with cash. Subject to certain exceptions, holders may require the Company to repurchase, for cash, all or part of the Convertible Notes at a price equal to 100% of the principal amount of the Convertible Notes being repurchased plus any accrued and unpaid interest. When the above described circumstances occur and the Convertible Notes are eligible for conversion prior to April 15, 2014 at the option of the Holders, we reclassify  (i) the portion of the Convertible Notes attributable to the conversion feature, which have not yet been accreted to its face value, from Additional paid in capital to Convertible debt and (ii) the carrying value of the Convertible Notes from Long-term debt to Notes payable and current maturities of long-term debt on our Consolidated Balance Sheet as of that period end. In addition, in cases where holders decide to convert prior to the maturity date, the Company immediately writes off the proportionate amount of remaining debt issue costs.  If in subsequent periods these circumstances do not occur and the Convertible Notes are not eligible for early conversion, the portion of the Convertible Notes attributable to the conversion feature are reclassified to Long-term debt and Additional paid in capital, respectively, on our Consolidated Balance Sheet. As the determination of whether the Holders may convert the Convertible Notes early is performed on a quarterly basis, the Convertible Notes may or may not meet the contingent conversion thresholds and therefore may be reclassified in future periods. Based upon the closing price of our common stock for the prescribed measurement period during the three months ended April 30, 2011, the contingent conversion threshold on the Convertible Notes was exceeded. As a result, the Convertible Notes were convertible at the option of any holder that provided a valid conversion notice prior to July 31, 2011. We received conversion notices from holders of an immaterial amount of the Convertible Notes during the conversion period. Based upon the closing price of our common stock for the prescribed measurement periods during subsequent periods, the contingent conversion thresholds on the Convertible Notes were not exceeded. In connection with the sale of the Convertible Notes, the Company purchased call options for $125 million. The call options cover 11,337,870 shares of common stock, subject to adjustments, at an exercise price of $50.27. The call options are intended to minimize share dilution associated with the Convertible Notes. In addition, in connection with the sale of the Convertible Notes, the Company also entered into separate warrant transactions whereby, the Company sold warrants for $87 million to purchase in the aggregate 11,337,870 shares of common stock, subject to adjustments, at an exercise price of $60.14 per share of common stock. As the call options and warrants are indexed to our common stock, we recognized them in permanent equity in Additional paid in capital, and will not recognize subsequent changes in fair value as long as the instruments remain classified as equity.  As a result of the conversion notices received prior to July 31, 2011, an immaterial number of call options were exercised by the Company to match the number of shares covered by the conversion notices received.  The number of warrants outstanding remains unchanged as none were exercised.Our majority-owned dealerships incur debt to finance their inventories, property, and equipment. The various dealership debt instruments have interest rates that range from 4.9% to 6.8% and maturities that extend to 2017. Included in our financing arrangements and capital lease obligations are financing arrangements of $113 million and $203 million as of October 31, 2011 and 2010, respectively. These arrangements involve the sale and leaseback of manufacturing equipment considered integral equipment. Accordingly, these arrangements are accounted for as financings. Inception dates of these arrangements range from April 2000 to June 2002, remaining terms range from 8 months to 3 years, effective interest rates vary from 3.2% to 4.0%, and buyout option exercise dates ranged from December 2007 to September 2009. In addition, the amount of financing arrangements and capital lease obligations include $5 million and $18 million of capital leases for real estate and equipment as of October 31, 2011 and October 31, 2010, respectively. Interest rates used in computing the net present value of the lease payments under capital leases ranged from 6.7% to 8.6%. Financial Services OperationsTRAC, our consolidated SPE, utilized a $100 million funding facility arrangement that provided for the funding of eligible retail accounts receivables. Subsequent to the adoption of new accounting guidance on accounting for transfers of financial assets, transfers of finance receivables from our Financial Services segment to the TRAC funding facility completed prior to November 1, 2010 retained their sale accounting treatment while transfers of finance receivables subsequent to November 1, 2010 no longer receive sale accounting treatment. Accordingly, borrowings secured by the transferred receivables are included in Notes payable and current maturities of long-term debt within our Consolidated Balance Sheet as of October 31, 2011. In January 2011, the maturity of the funding facility maturity was extended to March 2011, and in March 2011, the funding facility was refinanced with a maturity date of March 2012. As of October 31, 2011, all borrowings of the SPE are included in our consolidated financial statements.Effective July 31, 2010, the terms of the wholesale trust agreement were amended to allow NFC, as transferor, an element of control over the transferred receivables and control over eligibility of receivables available for transfer. This amendment disqualifies the Master Trust as a QSPE and therefore disqualifies transfers of receivables to the Master Trust from sale accounting treatment. As of July 31, 2010, liabilities of the trust of $600 million have been recognized as borrowings secured by the underlying receivables. For additional information, see Note 4, Finance receivables. In May 2010, our wholly owned subsidiary Navistar Financial Retail Receivables Corporation (“NFRRC”) issued secured notes for $919 million. A portion of the proceeds were used to pay off certain existing retail secured borrowings and the remaining portion was used to pay off the revolving retail warehouse facility within the Truck Retail Installment Paper Corporation (“TRIP”) of $500 million at maturity on June 15, 2010. In October 2010, NFRRC issued secured notes for $290 million. These proceeds were used primarily to pay-off certain existing secured borrowings and closeout the related interest rate swap position. In December 2009, NFC refinanced the revolving credit agreement dated July 2005, as amended, with a $815 million, three-year facility that was scheduled to mature in December 2012, with an interest rate of LIBOR plus 425 basis points (“Credit Agreement”). The Credit Agreement contains a term loan of $365 million and a revolving loan of $450 million with a Mexican sub-revolver of $100 million which was used by NIC's Mexican financial services operations. Under the Credit Agreement, NFC is subject to customary operational and financial covenants including an initial minimum collateral coverage ratio of 120%, increasing to 135% effective November 2010, and 150% effective November 2011. Concurrent with the refinancing in December 2009, Navistar Financial Asset Sales Corporation issued borrowings secured by asset backed securities of $225 million and NFC issued a term loan secured by retail notes and leases of $79 million with monthly scheduled principal payments through March 2013, with weighted average interest rates of 5.7% and 5.9%, respectively. In December 2011, the Credit Agreement was refinanced with a five-year $840 million facility consisting of a $340 million term loan and a $500 million revolving line of credit. The new facility is subject to customary operational and financial covenants. Quarterly principal payments on the term portion will be $4 million for the first eight quarters, $9 million for the next eleven quarters, with the balance due at maturity. TRIP, a special purpose, wholly-owned subsidiary of NFC, had a $500 million revolving retail facility that matured and was paid in June 2010. The facility was subject to optional early redemption in full without penalty or premium upon satisfaction of certain terms and conditions on any date on or after April 15, 2010. NFC used TRIP to temporarily fund retail notes and retail leases, other than operating leases, and this facility was used primarily during the periods prior to the securitization of retail notes and finance leases. NFC retained a repurchase option against the retail notes and leases sold into TRIP; therefore, TRIP's assets and liabilities were included in our Consolidated Balance Sheets. The majority of asset-backed debt is issued by consolidated SPEs and is payable out of collections on the finance receivables sold to the SPEs. This debt is the legal obligation of the SPEs and not NFC. The balance outstanding was $1.7 billion and $1.7 billion as of October 31, 2011 and 2010, respectively. The carrying amount of the retail notes, wholesale notes and finance leases used as collateral was $1.9 billion as of October 31, 2011 and 2010. In November 2009, we exercised our right to pay off retail securitization debt of $67 million in advance of final maturity. NFC enters into secured borrowing agreements involving vehicles subject to operating and finance leases with retail customers. The balances are classified under financial services operations debt as borrowings secured by leases. In connection with the securitizations and secured borrowing agreements of certain of its leasing portfolio assets, NFC and its subsidiary, Navistar Leasing Services Corporation (“NLSC”), have established Navistar Leasing Company (“NLC”), a Delaware business trust. NLC holds legal title to leased vehicles and is the lessor on substantially all leases originated by NFC. NLSC owns beneficial interests in the titles held by NLC and has transferred other beneficial interests issued by NLC to purchasers under secured borrowing agreements and securitizations. Neither the beneficial interests held by purchasers under secured borrowing agreements or the assets represented thereby, nor legal interest in any assets of NLC, are available to NLSC, NFC, or its creditors. The balance of the secured borrowings issued by NLC totaled $6 million and $7 million as of October 31, 2011 and 2010, respectively. International Truck Leasing Corporation (“ITLC”), a special purpose, wholly-owned subsidiary of NFC, provides NFC with another entity to obtain borrowings secured by leases. The balances are classified under financial services operations debt as borrowings secured by leases. ITLC's assets are available to satisfy its creditors' claims prior to such assets becoming available for ITLC's use or to NFC or affiliated companies. The balance of these secured borrowings issued by ITLC totaled $64 million and $105 million as of October 31, 2011 and 2010, respectively. The carrying amount of the finance and operating leases used as collateral was $70 million and $107 million as of October 31, 2011 and 2010, respectively. ITLC does not have any unsecured debt. We borrow funds denominated in U.S. dollars and Mexican pesos to be used for investment in our Mexican financial services operations. As of October 31, 2011, borrowings outstanding under these arrangements were $348 million, of which 21% is denominated in dollars and 79% in pesos. As of October 31, 2010, borrowings outstanding under these arrangements were $295 million, of which 17% is denominated in dollars and 83% in pesos. The interest rates on the dollar-denominated debt are at a negotiated fixed rate or at a variable rate based on LIBOR, and the interest rates on peso-denominated debt are based on the Interbank Interest Equilibrium Rate. As of October 31, 2011 and 2010, these borrowings included commercial paper of $70 million and $67 million, respectively. The remaining borrowings are effectively secured by the Mexican finance receivables. Future Maturities The aggregate contractual annual maturities for debt as of October 31, 2011, are as follows:   ManufacturingOperations(A)  FinancialServicesOperations(B)  Total  (in millions)      2012 $99 $1,280 $1,3792013 109 219 3282014 615 454 1,0692015 21 62 832016 8 91 99Thereafter 1,234 770 2,004Total debt 2,086 2,876 4,962Less: Unamortized discount (106) — (106)Net debt $1,980 $2,876 $4,856______________________ (A) Amounts include the borrowing of $100 million under the Asset-Based Credit Facility in November 2011, reflected as being due in 2017. (B) Amounts reflect the NFC refinancing of its bank credit facility in December 2011 with a five-year revolving line of credit and term loan, totaling $840 million, which shifted certain debt maturities to be largely due in 2017.Debt and Lease Covenants We have certain public and private debt agreements, including the indenture for our Senior Notes and the Tax Exempt Bonds and the Asset-Based Credit Facility, which limit our ability to incur additional indebtedness, pay dividends, buy back our stock, and take other actions. The terms of our Convertible Notes do not contain covenants that could limit the amount of debt we may issue, or restrict us from paying dividends or repurchasing our other securities. However, the Convertible Notes Indenture defines circumstances under which the Company would be required to repurchase the Convertible Notes and includes limitations on consolidation, merger, and sale of the Company's assets. As of October 31, 2011, we were in compliance with these covenants. We are also required under certain agreements with public and private lenders of NFC to ensure that NFC and its subsidiaries maintain their income before interest expense and income taxes at not less than 125% of their total interest expense. Under these agreements, if NFC's consolidated income, including capital contributions made by NIC or Navistar, Inc., before interest expense and income taxes is less than 125% of its interest expense (“fixed charge coverage ratio”), NIC or Navistar, Inc. must make payments to NFC to achieve the required ratio. During the years ended October 31, 2011 and 2010, no such payments were made. In 2009, $20 million of such payments were required and made from Navistar, Inc. to NFC to ensure compliance with the covenant. Our Mexican financial services operations also have debt covenants, which require the maintenance of certain financial ratios. As of October 31, 2011, we were in compliance with those covenants. |
