Comparing IFRS with US GAAP

An e-scooter company, Zoe Inc, incurs total R&D costs of $2.5m in 2019, of which $1,200,000 have been identified to relate to development activities. 80% of these development activities have been identified to relate to a specific product the ZOE-1 scooter which meets the following criteria of the IFRS for the capitalization of development costs as an internally generated intangible asset:

i. The product, ZOE-1, is technically feasible to complete

ii. The completed product, ZOE-1, is intended for sale

iii. Zoe Inc has the ability to sell the product in the market

iv. It is highly probable that future economic benefits will be generated from sales of ZOE-1 in the market v. Zoe Inc has adequate technical, financial, and other resources to complete the production process of ZOE-1 for sale

vi. Zoe Inc has the ability to reliably measure expenditure related to the development of ZOE-1

The scooter was quickly built and marketed in 2020 (assume for a full year) and its expected to have a marketable life spread evenly over 4 years.

What would be the total expenses charge and intangible asset capitalized in 2019 and 2020 for the above activities only under US GAAP?
