US Tax Reform- Financial Statement Impact While we are continuing to review the 2017 US Tax Cuts and Jobs Act (Tax Act), which lowers the U.S. Corporate tax rate to 21%, we want to highlight two items: (1) • On a go-forward basis, we currently expect a significant portion of our income to qualify as Foreign Derived Intangible Income (FDII) which, under the Tax Act, would be subject to an even lower tax rate of 13.1%. • Given the lower go-forward tax rate, we expect to record in Q4 2017 a one-time, non-cash charge of approximately $40M - $55M related to revaluation of Deferred Tax Assets and Liabilities. The reevaluation is necessary as the lower tax rate under the Tax Act reduces the size of the Deferred Tax Assets and Liabilities which had been previously determined based on a higher corporate tax rate. (1) The ultimate impact of tax reform on our Deferred Tax Assets and Liabilities and our future effective tax rate is continuing to be reviewed by the Company and may be affected by, among other things, future regulations or guidance promulgated by the IRS, FASB and others regarding the implementation of the Tax Act. 12 © 2018 InterDigital, Inc.
