1) The document discusses rules for recognizing intangible assets, research and development costs, and software development costs under international accounting standards.
2) For intangible assets to be recognized, they must be identifiable, provide probable future economic benefits, and the entity must control those benefits. Research costs cannot be capitalized as the benefits are uncertain, but development costs can be if certain criteria are met.
3) For software developed internally, costs in the application development stage can be capitalized but preliminary and post-implementation costs must be expensed. Capitalization ends when testing is complete and impairment tests are required if projects become improbable.
