Revenue from Contract with Customer [Abstract]

Revenue

REVENUEThe Company recognizes revenue from the sale of manufactured products and services when control of promised goods or services are transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

Disaggregation of Revenues

Beginning in 2020, sales were moved within product and service offering categories to reflect a strategic realignment within the Company's matrix organizational structure. Comparative results for the three and nine months ended September 30, 2020 have been adjusted to reflect this modification. Additionally, product and service offering category names were revised as follows: Services & software solutions changed to Service & spares, and I.T. edge & infrastructure changed to Integrated rack solutions. There was no change in the description of the Critical infrastructure & solutions offering.

The following table disaggregates our revenue by business segment, product and service offering and timing of transfer of control:
