c. AT&T’s operating income is 8.8% of revenues, while Verizon’s operating income to revenues is 15.4%. Verizon appears to be more efficient in generating operating income from revenues. AT&T’s cost of services is 45.8% of revenues, while Verizon’s is over six percentage points less at 39.3% of revenues. This difference is a largecontributor to Verizon’s superior operating income-to-revenues efficiency. The other two expense items essentially cancel each other out in that the selling and marketing expenses are 30.0% of revenues for AT&T, while Verizon’s are slightly larger at 32.3% of revenues. In contrast, the depreciation expense is 15.4% of revenues for AT&T and only 13.0% for Verizon. In summary, it appears that Verizon is able to generate more operating income per sales dollar, mostly because of a lower cost of services per sales dollar in comparison to AT&T.
