EXHIBIT 99.1

Additional Financial Information (Unaudited)

The following additional financial information is provided based upon the continuing interest of certain stockholders and creditors to assist them in understanding our core Manufacturing operations with our Financial Services operations on an after-tax equity basis. Our Manufacturing operations, for this purpose, include our North America Truck segment, North America Parts segment, Global Operations segment, and Corporate items. The Manufacturing operations financial information represents non-GAAP financial measures. These non-GAAP financial measures should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with U.S. GAAP. The reconciling differences between these non-GAAP financial measures and our U.S. GAAP condensed consolidated financial statements in Item 1, Financial Statements, are our Financial Services operations, which are included on an after-tax equity basis. Certain of our subsidiaries in our Manufacturing operations have debt outstanding with our Financial Services operations (“intercompany debt”). In the condensed statements of assets, liabilities, and stockholders' equity (deficit), the intercompany debt is reflected as accounts payable. The change in the intercompany debt is reflected in the net cash provided by operating activities in the condensed statements of cash activity.

Beginning in the first quarter of 2013, the Company began reporting the operating results of WCC and certain operating results of Monaco as discontinued operations. The Company's previously issued condensed statements of revenues and expenses have been recast to reflect this change.
