RESEARCH AND DEVELOPMENT Development costs that are directly attributable to the design and testing of identifiable and unique software products controlled by SES are recognized as intangible assets when the following criteria are met:

| • |     | it is technically feasible to complete the software product so that it will be available for use; |

| • |     | management intends to complete the software product and use or sell it; |

| • |     | there is an ability to use or sell the software product; |

| • |     | it can be demonstrated how the software product will generate probable future economic benefits; |

| • |     | adequate technical, financial, and other resources to complete the development and to use or sell the software 
 product are available; and                                                                                     |

| • |     | the expenditure attributable to the software product during its development can be reliably measured. |

Directly attributable costs that are capitalized as part of the software product include the software development employee costs and an appropriate portion of relevant overheads. Other development expenditures that do not meet these criteria are recognized as an expense as incurred. Software development costs recognized as assets are amortized over their estimated useful life, not exceeding seven years.
