operating income

Sales in 2012 were $443 billion, and operating income was $15.766 billion, a margin of about 3.5 percent.

In 2012 it reported revenue of $3.436 billion and operating income of $420 million.

In 2002 Time Inc. had $5.4 billion in revenue and $881 million in operating income.

Operating income is also being squeezed, declining 47 percent to $39 million from $74 million in 2008.

I would suggest the average net railway operating income of the three years ending June 30, 1917.
