| Finance Receivables        | Finance ReceivablesFinance receivables are receivables of our Financial Services operations. Finance receivables generally consist of wholesale notes and accounts, as well as retail notes, finance leases and accounts. Total finance receivables reported on the Consolidated Balance Sheets are net of an allowance for doubtful accounts. Total assets of our Financial Services operations net of intercompany balances are $2.4 billion and $2.6 billion as of October 31, 2013 and October 31, 2012, respectively. Included in total assets are finance receivables of $1.9 billion and $2.1 billion as of October 31, 2013 and October 31, 2012, respectively. We have two portfolio segments of finance receivables based on the type of financing inherent to each portfolio. The retail portfolio segment represents loans or leases to end-users for the purchase or lease of vehicles. The wholesale portfolio segment represents loans to dealers to finance their inventory.Our Finance receivables, net, consist of the following:(in millions)2013 2012Retail portfolio$751 $1,048Wholesale portfolio1,207 1,128Total finance receivables1,958 2,176Less: Allowance for doubtful accounts23 27Total finance receivables, net1,935 2,149Less: Current portion, net(A)1,597 1,663Noncurrent portion,net$338 $486_________________________(A)The current portion of finance receivables is computed based on contractual maturities. Actual cash collections typically vary from the contractual cash flows because of prepayments, extensions, delinquencies, credit losses, and renewals.As of October 31, 2013, contractual maturities of our finance receivables are as follows: (in millions)Retail Portfolio Wholesale Portfolio TotalDue in:     2014$434 $1,207 $1,6412015169 — 1692016112 — 112201755 — 55201826 — 26Thereafter15 — 15Gross finance receivables811 1,207 2,018Unearned finance income60 — 60Total finance receivables$751 $1,207 $1,958SecuritizationsOur Financial Services segment transfers wholesale notes, retail accounts receivable, retail notes, finance leases, and operating leases through special purpose entities ("SPEs"), which generally are only permitted to purchase these assets, issue asset-backed securities, and make payments on the securities. In addition to servicing receivables, our continued involvement in the SPEs may include an economic interest in the transferred receivables and, in some cases, managing exposure to interest rates using interest rate swaps and interest rate caps. There were no transfers of finance receivables that qualified for sale accounting treatment as of October 31, 2013 and October 31, 2012, and as a result, the transferred finance receivables are included in our Consolidated Balance Sheets and the related interest earned is included in Finance revenues. We transfer eligible finance receivables into the retail owner trust or the wholesale note owner trust in order to issue asset-backed securities. These trusts are VIEs of which we are determined to be the primary beneficiary and, therefore, the assets and liabilities of the trusts are included in our Consolidated Balance Sheets. The outstanding balance of finance receivables transferred into these VIEs was $948 million and $1.1 billion as of October 31, 2013 and October 31, 2012, respectively. Other finance receivables pledged to secure borrowings were $4 million and $164 million as of October 31, 2013 and October 31, 2012, respectively.
