## Goodwill 

We had total goodwill of $45.3 million for the Unum International segment at December 31, 2020, of which, $40.2 million is attributed to the Unum UK reporting unit and $5.1 million is attributed to the Unum Poland reporting unit. Fair value of our reporting units is estimated using a combination of the income and market approaches and the key assumptions used are projected earnings and discount rate. To the extent that the future profitability of these reporting units deteriorates from current assumptions, the goodwill related to the reporting units could be at risk for impairment.
