Restructuring and Related Costs | The following table summarizes restructuring and separation costs by type that have been incurred through December 31, 2017 and are estimated to be incurred through the end of the Restructuring Plan (in millions). Estimated costs may be revised in future periods as these assumptions are updated:
|  | Year Ended December 31, 2017 |  | Estimated Remaining Costs |  | Estimated Total Cost (1)
Workforce reduction |  | $ | 299 |  |  | $ | 151 |  |  | $ | 450 |
Technology rationalization (2) |  | 33 |  |  | 97 |  |  | 130 |

Total restructuring and related expenses |  | $ | 497 |  |  | $ | 528 |  |  | $ | 1,025 |
(1) | Actual costs, when incurred, may vary due to changes in the assumptions built into the Restructuring Plan. Significant assumptions that may change when plans are finalized and implemented include, but are not limited to, changes in severance calculations, changes in the assumptions underlying sublease loss calculations due to changing market conditions, and changes in the overall analysis that might cause the Company to add or cancel component initiatives.
(2) | Contract termination costs included within Technology rationalization for the year ended December 31, 2017 were $1 million. Contract termination costs included within Lease consolidations for the year ended December 31, 2017 were $8 million. Contract termination costs included within Other costs associated with restructuring and separation were $3 million for the year ended December 31, 2017. Total estimated contract termination costs to be incurred under the Restructuring Plan associated with Technology rationalizations, Lease consolidations, and Other costs associated with restructuring and separation, respectively, are $10 million, $80 million, and $10 million.
(3) | Other costs associated with the Restructuring Plan include primarily those to separate the Divested Business, as well as moving costs and consulting and legal fees. These costs are generally recognized when incurred.
