Chen Communications has amortized a patent on a straight$-$line basis since it was acquired in $2021$

for $$50$ million. During $2024$ management decided that the benefits from the patent would be

received over a total period of $8$ years rather than the $20-$gear legal life being used to amortize the

cost$.$ Chen's $2024$ financial statements should include:

a$.$ a patent balance of $$34$ million.

b$.$ a patent balance of $$50$ million.

c$.$ patent amortization expense of $$2\mathrm{.}5$ million.

d$.$ patent amortization expense of $$5$ million.

Clear my choice
