Because the company would be eligible for the state's manufacturing and agriculture tax credit, the majority of the proposed tax incentives would be refunded to Foxconn, not used to offset its tax liability, according to the fiscal bureau.

The projections are based on the assumption that the company will start with 1,040 jobs in the second half of 2017 and create 13,000 jobs with an average salary of $53,875 by 2021. Employments levels are expected to then remain at that level.

The project would be responsible for an estimated 22,000 indirect and induced jobs by 2021, with average annual wages projected at about $51,000.

During the project's four-year construction period, an estimated 10,200 construction workers and equipment suppliers would be employed at an average annual compensation of about $59,600, including benefits. An estimated 6,000 indirect and induced jobs would be created during that period, with an average yearly compensation of $48,900.

The LFB report notes that "any cash-flow analysis that covers a period of nearly 30 years must be considered highly speculative, especially for a manufacturing facility and equipment that may have a limited shelf life."

Projections are subject to changes within the Foxconn company and to state laws.
