Development costs are expensed as incurred unless addressed by guidance in another ASC Topic. Development costs related to computer software developed for external use are capitalized once technological feasibility is established in accordance with specific criteria (ASC 985-20). In the case of software developed for internal use, only those costs incurred during the application development stage (as defined in ASC 350-40, Intangibles — Goodwill and Other — Internal-Use Software) may be capitalized.
