Answer:
$250,000
Explanation:
Analog's intangibles are patents, trademarks and goodwill, but only patents can be amortized.
Patents total cost are $2,500,000, amortized in 10 years = $2,500,000 / 10 = $250,000 per year.
Goodwill cannot be amortized because its life is indefinite. Trademarks can be renewed every 20 years, so their lives can be indefinite also. Assets with indefinite lives cannot be amortized.
Research and development costs are considered expenses.
