| 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 $2.1 billion and $2.5 billion as of October 31, 2016 and 2015, respectively. Included in total assets of our Financial Services operations are finance receivables of $1.7 billion and $2.0 billion as of October 31, 2016 and 2015, respectively. We have two portfolio segments of finance receivables that we distinguish based on the type of customer and nature of the 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 in our Consolidated Balance Sheets consist of the following: As of October 31,(in millions)2016 2015Retail portfolio$499 $554Wholesale portfolio1,199 1,467Total finance receivables1,698 2,021Less: Allowance for doubtful accounts21 26Total finance receivables, net1,677 1,995Less: Current portion, net(A)1,457 1,779Noncurrent portion, net$220 $216_________________________(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, 2016, contractual maturities of our finance receivables are as follows: (in millions)Retail Portfolio Wholesale Portfolio TotalDue in:     2017$294 $1,199 $1,4932018106 — 106201977 — 77202043 — 43202114 — 14Thereafter3 — 3Gross finance receivables537 1,199 1,736Less: Unearned finance income38 — 38Total finance receivables$499 $1,199 $1,698SecuritizationsOur Financial Services operations transfer wholesale notes, retail accounts receivable, finance leases, and operating leases to special purpose entities ("SPEs"), which generally are only permitted to purchase these assets, issue asset-backed securities, and make payments on the securities issued. 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 rate changes on the securities using interest rate swaps or interest rate caps. There were no transfers of finance receivables that qualified for sale accounting treatment as of October 31, 2016 and 2015, 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 wholesale note owner trusts 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 $829 million and $1.0 billion as of October 31, 2016 and 2015, respectively. Other finance receivables related to secured transactions that do not qualify for sale accounting treatment were $108 million and $96 million as of October 31, 2016 and 2015, respectively. For more information on assets and liabilities of consolidated VIEs and other securitizations accounted for as secured borrowings by our Financial Services segment, see Note 1, Summary of Significant Accounting Policies.Finance RevenuesThe following table presents the components of our Finance revenues in our Consolidated Statements of Operations: As of October 31,(in millions)2016 2015 2014Retail notes and finance leases revenue$38 $48 $64Wholesale notes interest107 97 80Operating lease revenue66 63 60Retail and wholesale accounts interest24 33 28Gross finance revenues235 241 232Less: Intercompany revenues100 96 79Finance revenues$135 $145 $153 |
