The principal amount of long-term debt maturing in each of the next five years is $21 in 2016, $771 in 2017, $1,039 in 2018, $1,140 in 2019, and $1,018 in 2020.

Public Debt—In early 2014, holders of $575 principal amount of Alcoa’s 5.25% Convertible Notes due March 15, 2014 (the “2014 Notes”) exercised their option to convert the 2014 Notes into 89 million shares of Alcoa common stock. The conversion rate for the 2014 Notes was 155.4908 shares of Alcoa’s common stock per $1,000 (in full dollars) principal amount of notes, equivalent to a conversion price of $6.43 per share. The difference between the $575 principal amount of the 2014 Notes and the $89 par value of the issued shares increased Additional capital on the accompanying Consolidated Balance Sheet. This transaction was not reflected in the accompanying Statement of Consolidated Cash Flows as it represents a noncash financing activity.

In September 2014, Alcoa completed a public debt offering under its shelf registration statement for $1,250 of 5.125% Notes due 2024 (the “2024 Notes”). Alcoa received $1,238 in net proceeds from the public debt offering reflecting an original issue discount. The net proceeds were used, together with the net proceeds of newly issued mandatory convertible preferred stock (see Note R), to finance the cash portion of the acquisition of Firth Rixson (see Note F). The original issue discount was deferred and is being amortized to interest expense over the term of the 2024 Notes. Interest on the 2024 Notes will be paid semi-annually in April and October, commencing April 2015. Alcoa has the option to redeem the 2024 Notes, as a whole or in part, at any time or from time to time, on at least 30 days, but not more than 60 days, prior notice to the holders of the 2024 Notes at a redemption price specified in the 2024 Notes. The 2024 Notes are subject to repurchase upon the occurrence of a change in control repurchase event (as defined in the 2024 Notes) at a repurchase price in cash equal to 101% of the aggregate principal amount of the 2024 Notes repurchased, plus any accrued and unpaid interest on the 2024 Notes repurchased. The 2024 Notes rank pari passu with Alcoa’s other unsecured unsubordinated indebtedness.

BNDES Loans—Alcoa Alumínio (Alumínio) has a loan agreement with Brazil’s National Bank for Economic and Social Development (BNDES) that provides for a financing commitment of $397 (R$687), which is divided into three subloans and was used to pay for certain expenditures of the Estreito hydroelectric power project. Interest on the three subloans is a Brazil real rate of interest equal to BNDES’ long-term interest rate, 7.00% and 5.00% as of December 31, 2015 and 2014, respectively, plus a weighted-average margin of 1.48%. Principal and interest are payable monthly, which began in October 2011 and end in September 2029 for two of the subloans totaling R$667 and began in July 2012 and end in June 2018 for the subloan of R$20. This loan may be repaid early without penalty with the approval of BNDES.

As of December 31, 2015 and 2014, Alumínio’s outstanding borrowings were $136 (R$522) and $209 (R$560), respectively, and the weighted-average interest rate was 8.49%. During 2015 and 2014, Alumínio repaid $15 (R$48) and $20 (R$47), respectively, of outstanding borrowings. Additionally, Alumínio borrowed less than $1 (R$1) and $1 (R$2) under the loan in 2015 and 2014, respectively.

Alumínio has another loan agreement with BNDES that provides for a financing commitment of $85 (R$177), which also was used to pay for certain expenditures of the Estreito hydroelectric power project. Interest on the loan is a Brazil real rate of interest equal to BNDES’ long-term interest rate plus a margin of 1.55%. Principal and interest are payable monthly, which began in January 2013 and end in September 2029. This loan may be repaid early without penalty with the approval of BNDES. As of December 31, 2015 and 2014, Alumínio’s outstanding borrowings were $38 (R146) and $58 (R$156), respectively, and the interest rate was 6.55%. During 2015 and 2014, Alumínio repaid $3 (R$10) and $5 (R$11), respectively, of outstanding borrowings.

Credit Facilities. On July 25, 2014, Alcoa entered into a Five-Year Revolving Credit Agreement (the “Credit Agreement”) with a syndicate of lenders and issuers named therein. The Credit Agreement provides a $4,000 senior unsecured revolving credit facility (the “Credit Facility”), the proceeds of which are to be used to provide working capital or for other general corporate purposes of Alcoa. Subject to the terms and conditions of the Credit Agreement, Alcoa may from time to time request increases in lender commitments under the Credit Facility, not to exceed $500 in aggregate principal amount, and may also request the issuance of letters of credit, subject to a letter of credit sublimit of $1,000 under the Credit Facility.

The Credit Facility was scheduled to mature on July 25, 2019; however, on July 7, 2015, Alcoa received approval for a one-year extension of the maturity date by the lenders and issuers that support the Credit Facility. As such, the Credit Facility now matures on July 25, 2020, unless extended or earlier terminated in accordance with the provisions of the Credit Agreement. Alcoa may make one additional one-year extension request during the remaining term of the Credit Facility, subject to the lender consent requirements set forth in the Credit Agreement. Under the provisions of the Credit Agreement, Alcoa will pay a fee of 0.25% (based on Alcoa’s long-term debt ratings as of December 31, 2015) of the total commitment per annum to maintain the Credit Facility.

The Credit Facility is unsecured and amounts payable under it will rank pari passu with all other unsecured, unsubordinated indebtedness of Alcoa. Borrowings under the Credit Facility may be denominated in U.S. dollars or euros. Loans will bear interest at a base rate or a rate equal to LIBOR, plus, in each case, an applicable margin based on the credit ratings of Alcoa’s outstanding senior unsecured long-term debt. The applicable margin on base rate loans and LIBOR loans will be 0.50% and 1.50% per annum, respectively, based on Alcoa’s long-term debt ratings as of December 31, 2015. Loans may be prepaid without premium or penalty, subject to customary breakage costs.

The Credit Agreement replaces Alcoa’s Five-Year Revolving Credit Agreement, dated as of July 25, 2011 (the “Former Credit Agreement”), which was scheduled to mature on July 25, 2017. The Former Credit Agreement, which had a total capacity of $3,750 and was undrawn, was terminated effective July 25, 2014.

The Credit Agreement includes covenants substantially similar to those in the Former Credit Agreement, including, among others, (a) a leverage ratio, (b) limitations on Alcoa’s ability to incur liens securing indebtedness for borrowed money, (c) limitations on Alcoa’s ability to consummate a merger, consolidation or sale of all or substantially all of its assets, and (d) limitations on Alcoa’s ability to change the nature of its business. As of December 31, 2015, Alcoa was in compliance with all such covenants.

The obligation of Alcoa to pay amounts outstanding under the Credit Facility may be accelerated upon the occurrence of an “Event of Default” as defined in the Credit Agreement. Such Events of Default include, among others, (a) Alcoa’s failure to pay the principal of, or interest on, borrowings under the Credit Facility, (b) any representation or warranty of Alcoa in the Credit Agreement proving to be materially false or misleading, (c) Alcoa’s breach of any of its covenants contained in the Credit Agreement, and (d) the bankruptcy or insolvency of Alcoa.

There were no amounts outstanding at December 31, 2015 and 2014 and no amounts were borrowed during 2015 or 2014 under the Credit Facility. Also, there were no amounts borrowed during 2014 related to the Former Credit Agreement.

In addition to the Credit Agreement above, Alcoa has a number of other credit agreements that provide a combined borrowing capacity of $990 as of December 31, 2015, of which $890 is due to expire in 2016 and $100 is due to expire in 2017. The purpose of any borrowings under these credit arrangements is to provide for working capital requirements and for other general corporate purposes. The covenants contained in all these arrangements are the same as the Credit Agreement (see above).

In 2015 and 2014, Alcoa borrowed and repaid $1,890 and $1,640, respectively, under the respective credit arrangements. The weighted-average interest rate and weighted-average days outstanding of the respective borrowings during 2015, 2014, and 2013 were 1.61%, 1.54%, and 1.57%, respectively, and 69 days, 67 days, and 213 days, respectively.

Short-Term Borrowings. At December 31, 2015 and 2014, Short-term borrowings were $38 and $54, respectively. These amounts included $32 and $50 at December 31, 2015 and 2014, respectively, related to accounts payable settlement arrangements with certain vendors and third-party intermediaries. These arrangements provide that, at the vendor’s request, the third-party intermediary advances the amount of the scheduled payment to the vendor, less an appropriate discount, before the scheduled payment date and Alcoa makes payment to the third-party intermediary on the date stipulated in accordance with the commercial terms negotiated with its vendors. Alcoa records imputed interest related to these arrangements in Interest expense on the accompanying Statement of Consolidated Operations.

Commercial Paper. Alcoa had no outstanding commercial paper at December 31, 2015 and 2014. In 2015 and 2014, the average outstanding commercial paper was $198 and $257, respectively. Commercial paper matures at various times within one year and had an annual weighted average interest rate of 0.6%, 0.6%, and 0.8% during 2015, 2014, and 2013, respectively.
