Research and Development- IFRS vs US GAAP

Please clarify on rules relation to expensing and capitalising of R&D in IFRS vs US gaap

IFRS: research phase expensed, development phase (ie after technological feasability confirmed) can be capitalized

GAAP: both research and development expense; exception is software: when for sale treat like in IFRS, when for internal use both phases can be capitalized
