I want to know the answer to the following question:
IBM's net profit margins were 16.5% in what year?
All the background I'm provided with is that "IBM's operating margin expanded from 16.8% in 2004 to 24.3% in 2013, and net profit margins expanded from 9.0% in 2004 to 16.5% in 2013.". Is that enough to answer the question?
Answer: yes
