* ND Holdings, LLC is the ultimate parent entity of Navistar Defense, LLC in the recapitalized Navistar Defense business.

See accompanying notes to unaudited pro forma condensed financial information.

The following pro forma adjustments have been reflected in the unaudited pro forma condensed consolidated financial information.

(a) Represents cash proceeds of the sale as if the Navistar Defense Transaction had closed on October 31, 2018. The cash proceeds reflected on the October 31, 2018 pro forma balance sheet will likely be different from the actual cash proceeds received in the Navistar Defense Transaction due to differences in the adjustment for net working capital.

(b) Reflects the pro forma adjustment for the effects of the Navistar Defense Transaction to (i) remove the assets and liabilities associated with the disposition of Navistar Defense and not retained by the Company; and (ii) eliminate the revenues and expenses associated with Navistar Defense for the year ended October 31, 2018.

(c) Reflects the Company’s equity method investment in Navistar Defense, which was determined based on an allocation of the preliminary fair value of the equity interest retained by the Company. Investments in entities for which the Company has the ability to exercise significant influence but does not have financial or operating control, are accounted for under the equity method of accounting.

The Company performed a preliminary valuation analysis of the fair market value of the equity method investment as of October 31, 2018. Using the total preliminary value of Navistar Defense, the Company has estimated the allocation of value to the various classes of shares. This preliminary estimate of the fair value of the equity method investment has been used to prepare pro forma adjustments in the pro forma balance sheet and income statement. The final valuation for the equity method investment will be determined when the Company has completed the detailed valuations and necessary calculations. Accordingly, under the equity method of accounting, the fair value of $13 of the net assets retained in the Navistar Defense Transaction form the basis for the Company’s investment in Navistar Defense. The value of the equity method investment reflected on the October 31, 2018 pro forma balance sheet will likely be different from the actual value due to differences in the adjustment for net working capital. The Company also reflected its share of the net earnings in Navistar Defense of $22 in pro forma consolidated net income under the caption “Equity in earnings of unconsolidated affiliates”.

(d) Represents the accrual of $3 for transaction costs which became payable upon the closing of the Navistar Defense Transaction.

(e) Reflect a $12 deferred gain related to an exclusive long-term agreement entered into by Navistar, Inc., a subsidiary of the Company, in connection with the closing of the Navistar Defense Transaction, to supply commercial parts and chassis to Navistar Defense (the “Supply Agreement”) of which $3 is classified under the caption “other current liabilities” and $9 is classified under the caption “other noncurrent liabilities”. The value of the liability was determined based on estimated sales over the minimum fifteen-year term of the Supply Agreement and the pricing terms set forth within. All estimates in the determination of the value of the liability to recognize were based on assumptions that management believes are reasonable. This liability will be amortized into revenue over the life of the Supply Agreement based on projected annual sales volumes.

(f) Represents the transfer of certain employee benefit plan and other obligations of $3 at October 31, 2018, which are directly attributable to Navistar Defense.

(g) The gain on the Navistar Defense Transaction assuming the Company had completed the sale as of October 31, 2018 is as follows:

Net cash proceeds	$	95
Fair value of the retained equity interest		13
Net assets sold		(25	)
Adjustment for transaction costs		(3	)
Off-market supply agreement		(12	)
Accumulated Other Comprehensive Income		1
Gain on sale	$	69

The gain on the Navistar Defense Transaction includes the recognition of the accumulated other comprehensive income from the Company’s currency translation adjustments.

As the gain related to the Navistar Defense Transaction and use of the proceeds do not have a continuing impact on the Company’s operations, the gain is only reflected in the retained earnings on the unaudited pro forma condensed consolidated balance sheet. The gain on the Navistar Defense Transaction, based on the October 31, 2018 balance sheet, will likely be different from the actual gain on the sale that will be realized because of the differences in adjustments for certain current year charge outs and working capital, and the estimation of transaction costs in determining the net cash proceeds from the transaction.

(h) No pro forma adjustment was made for taxes due to the Company’s valuation allowance.

(i) Represents the sale of products between the Company and Navistar Defense. These sales are normally eliminated upon consolidation and had no impact on gross margin or operating income; however, they are expected to continue subsequent to the sale under the Supply Agreement.

The sales of products from the Company to Navistar Defense were $77 for the year ended October 31, 2018 based on the volumes sold and terms as defined in the Supply Agreement. Such sales increased the pro forma income from continuing operations before income taxes and earnings in unconsolidated affiliates by $6.

(j) Removal of $3 of transaction costs in the year ended October 31, 2018. These costs directly related to the Navistar Defense Transaction and will not recur and as such, have been removed from the unaudited pro forma consolidated statement of income.

(k) Represents $3 of certain general corporate overhead expenses that were allocated to Navistar Defense, but not specifically identifiable to Navistar Defense. Such expenses are presented as part of the Company’s continuing operations.

(l) To record $1 of fee income related to a Transition Services Agreement entered into in connection with the closing of the Navistar Defense Transaction whereby the Company will provide certain services to Navistar Defense for no less than 12 months after the closing date.

(m) Represents the reduction of the expense related to the supplemental profit sharing program in the amount of $15 as the expense is based off the Company’s qualifying profits in relation to fixed contribution tiers. The change in the tiers was deemed to be directly attributable to the Navistar Defense Transaction.
