| (1) | Grundartangi’s tolling revenues include a premium based on the European Union (“EU”) import duty for primary aluminum.  In May 2007, the EU members reduced the EU import duty for primary aluminum from six percent to three percent and agreed to review the new duty after three years.  This decrease in the EU import duty for primary aluminum negatively impacts Grundartangi’s revenues and further decreases would also have a negative impact on Grundartangi’s revenues, but it is not expected to have a material effect on our financial position and results of operations. |

| · | As part of our operational restructuring, we have curtailed and may continue to curtail operations at one or more of our facilities, which actions have required us to incur and may require us to further incur substantial costs and subject us to substantial risks in the future.  The failure to successfully implement our operational restructuring or to achieve its intended benefits could have a material adverse effect on our business, financial condition, results of operations and liquidity. |
| · | A continuation or worsening of global financial and economic conditions could adversely impact our financial position and results of operations.                                                                                                                                                                                                                                                                                                                                                                         |
| · | Our ability to access the credit and capital markets on acceptable terms to obtain funding for our operations and capital projects may be limited due to our credit ratings, our financial condition or the deterioration of these markets.                                                                                                                                                                                                                                                                              |
| · | Poor performance in the financial markets and/or our curtailment actions could have significant and adverse effects on our pension funding obligations.                                                                                                                                                                                                                                                                                                                                                                  |
| · | The cyclical nature of the aluminum industry causes variability in our earnings and cash flows.                                                                                                                                                                                                                                                                                                                                                                                                                          |
| · | International operations expose us to political, regulatory, currency and other related risks.                                                                                                                                                                                                                                                                                                                                                                                                                           |
| · | If economic and political conditions in Iceland deteriorate further, our financial position and results of operations could be adversely impacted.                                                                                                                                                                                                                                                                                                                                                                       |
| · | Any future reductions in the duty on primary aluminum imports into the European Union (the “EU”) would decrease our revenues at our smelter in Grundartangi, Iceland (“Grundartangi”).                                                                                                                                                                                                                                                                                                           |
| · | Substantial additional delays in the completion of the Nordural Helguvik ehf smelter project (“Helguvik project”) may increase its cost, lower the project’s financial returns and impose other risks to completion that are not foreseeable today.                                                                                                                                                                                                                                                    |
| · | Our power supply agreements for the Helguvik project are subject to fulfillment of certain conditions, and there can be no assurance that these conditions will be met or that the cost required to meet the conditions makes the project impracticable or less attractive from a financial standpoint.                                                                                                                                                                                                                  |
| · | Changes in the relative cost and availability of certain raw materials and energy compared to the price of primary aluminum could adversely affect our operating results.                                                                                                                                                                                                                                                                                                                                                |
| · | Many of our contracts for raw materials, including certain contracts for alumina and electrical power, require us to take-or-pay for fixed quantities of such materials that may limit our ability to curtail unprofitable production capacity.                                                                                                                                                                                                                                                                          |
| · | Further consolidation within the metals industry could provide advantages to our competitors.                                                                                                                                                                                                                                                                                                                                                                                                                            |
| · | Disruptions in our power supplies could adversely affect our operations.                                                                                                                                                                                                                                                                                                                                                                                                                                                 |

| · | Despite our substantial level of debt, we may incur additional debt in the future.                                                                                                                                                                                                                                                                              |
| · | We depend upon intercompany transfers from our subsidiaries to meet our debt service obligations and any limitations on the ability of our subsidiaries to do so may adversely affect our ability to meet our debt service obligations.                                                                                                                         |
| · | We have implemented a Tax Benefit Preservation Plan and taken other efforts to protect against a possible limitation on our ability to use net operating losses (“NOLs”), tax credits and other tax assets, however, there can be no assurance that these actions will be effective or that the Tax Benefit Preservation Plan will remain in place. |
