Exhibit 99.4

WEIGHTED AVERAGE LIFE OF THE NOTES

The weighted average life of the notes will generally be influenced by the rate at which the principal balances of the receivables are paid, which payment may be in the form of scheduled amortization or prepayments. For this purpose, the term “prepayment” includes charge-offs, liquidations due to defaults and repurchases by the depositor or the seller or purchases by the servicer pursuant to the servicing agreement, as well as receipt of proceeds from credit life and casualty insurance policies. All of the receivables are prepayable at any time without penalty to the obligor. The rate of prepayment of automotive receivables is influenced by a variety of economic, social and other factors, including the fact that an obligor generally may not sell or transfer the financed vehicle securing a receivable without the consent of the servicer. Any reinvestment risk resulting from prepayment of receivables is borne entirely by the holders of the notes. See also “Legal Aspects of the Receivables—Transfer of Vehicles” in the prospectus.

Prepayments on automotive receivables can be measured relative to a prepayment standard or model. The model used in this private placement memorandum to present the projected weighted average life of the notes, the Absolute Prepayment Model, or “ABS,” assumes a rate of prepayment each month relative to the original number of receivables in a pool of receivables. ABS further assumes that all the receivables are uniform as to size and maturity and amortize at the same rate and that each receivable in each month of its life will either be paid as scheduled or be prepaid in full. For example, in a pool of receivables assumed to originally contain 10,000 uniform receivables, a 1% ABS rate means that 100 receivables prepay each month. ABS does not purport to be a historical description of prepayment experience or a prediction of the anticipated rate of prepayment of any pool of receivables, including the receivables owned by the trust.

As the rate of payment of principal of the notes will depend on the rate of payment, including prepayments, of the principal balance of the receivables, final payment of the offered notes could occur significantly earlier than the final scheduled distribution date for the offered notes.

The tables below under the heading “—Percent of Initial Note Principal Balance Outstanding at Various ABS Percentages” have been prepared on the basis of indicated ABS percentages. The indicated ABS percentages have been applied to the hypothetical pool of receivables.

The “hypothetical pool of receivables” is a pool of receivables equal to those receivables owned by the issuing entity on August 31, 2018. The table below represents a pool of receivables that have been further disaggregated into 50 smaller hypothetical pools having the characteristics set forth in the table below. The level scheduled monthly payment for each of the hypothetical pools is based on aggregate principal balance, annual percentage rate and remaining term to maturity as of the updated pool date such that each hypothetical pool set forth below will be fully amortized by the end of its remaining term to maturity.

In addition, the following assumptions have been used in preparing the tables below:

The actual characteristics and performance of the receivables will differ from the assumptions used in constructing the following tables. The assumptions used are hypothetical and have been provided only to give a general sense of how the principal cash flows might behave under varying prepayment scenarios. Investors are urged to make their investment decisions on a basis that includes their determination as to anticipated prepayment rates under a variety of the assumptions discussed herein.

It is very unlikely that the receivables will prepay at a constant level of ABS until maturity or that all of the receivables will prepay at the same level of ABS. Any difference between each of those assumptions and the actual characteristics and performance of the receivables, or actual prepayment experience, will affect the percentages of initial balances outstanding over time and the weighted average lives of the notes.

The following tables indicate the projected weighted average life of each class of notes and set forth the percent of the initial principal balance of each class of notes that is projected to be outstanding after each of the distribution dates shown at various constant ABS percentages.

Additional information on the effect of prepayment on the notes can be found under “Weighted Average Life of the Notes” in the prospectus.

Percent of Initial Note Principal Balance Outstanding at Various ABS Percentages

The weighted average life of each class of outstanding notes as set forth in each of the tables below is determined by (a) multiplying the amount of each principal payment on a note of that class by the number of years from the certificate closing date to the related distribution date, (b) adding the results, and (c) dividing the sum by the related initial principal balance of each class of notes. The calculation in the row in each of the tables below labeled “Weighted Average Life (Years) to Call” assumes that the servicer exercises its 10% clean-up call option to purchase the receivables on the earliest permissible date. The calculation in the row in each of the tables listed below labeled “Weighted Average Life (Years) to Maturity” assumes that the servicer does not exercise its 10% clean-up call option. If the servicer were to exercise its 10% clean-up call option, noteholders would receive all unpaid principal on their notes at the time of the call and each class of outstanding notes would cease to be outstanding.
