My source was:

``` The government has collected perhaps $180bn in IEEPA tariffs. Over the past year 1,800 companies—including Goodyear, a tyre-maker, and Costco, a retailer—have filed lawsuits to protect their right to a refund should the Supreme Court overturn them. They are now owed this money, equivalent to roughly 5% of the profits companies generated in America last year, or 0.6% of GDP—plus interest, compounded daily at an annual rate of 6-7%. ```
