Core services include base operations support; procurement; supply chain management; vehicle, maritime and aircraft sustainment services; IT services and energy consulting.
The operating segments reported below are the segments of the Company for which separate financial information is available and for which segment results are evaluated regularly by our Chief Executive Officer in deciding how to allocate resources and in assessing performance. We evaluate segment performance based on consolidated revenues and operating income. Net sales of our business segments exclude inter-segment sales as these activities are eliminated in consolidation.

Revenues are net of inter-segment eliminations. Corporate expenses are primarily selling, general and administrative expenses not allocated to segments. Corporate assets are primarily cash, property and equipment and investments held in separate trust.

In 2020 and 2019, we allocated depreciation and amortization expense to each segment based on the segment in which each asset was utilized. In 2018, the allocation method for certain amortization expenses was based on each segment’s percentage of overall cost. The primary reason for the change is to allocate depreciation and amortization expense to a specific segment depending on the asset deployment. Depreciation and amortization expense by segment for 2018 was not recast for these allocation changes, and this change did not impact our previously reported consolidated financial results. The impact for 2018, under the new allocation method, would have been a decrease in depreciation and amortization expense for the Federal and Defense segment of $8.1 million, with a corresponding increase for Aviation segment and Fleet segment of $3.7 million and $4.4 million, respectively.
Customer Information

Our revenues are derived from contract services performed for DoD agencies or federal civilian agencies and from the delivery of products to our commercial clients. The USPS, U.S. Army and Army Reserve, and U.S. Navy are our largest customers. Our customers also include various other government agencies and commercial entities. Our revenue by customer is as follows for the years ended December 31, (in thousands):
Years ended December 31,
Source of Revenues 2020 % 2019 % 2018 %
DoD $ 236,397  36  $ 304,334  41  $ 334,494  48 
Other government 216,957  33  205,775  27  212,118  30 
Commercial 208,305  31  242,518  32  150,606  22 
Total Revenues $ 661,659  100  $ 752,627  100  $ 697,218  100 

We do not measure revenue or profit by product or service lines, either for internal management or external financial reporting purposes, because it would be impractical to do so. Products offered and services performed are determined by contract requirements and the types of products and services provided for one contract bear no relation to similar products and services provided on another contract. Products and services provided vary when new contracts begin or current contracts expire. In many cases, more than one product or service is provided under a contract or contract task order. Accordingly, cost and revenue tracking are designed to best serve contract requirements and segregating costs and revenues by product or service lines in situations for which it is not required would be difficult and costly to both us and our customers.
