THG 2019 Proxy Statement

THE HANOVER INSURANCE GROUP 2019 PROXY STATEMENT 54 CEO Mr. Roche’s total compensation was calculated by using the same methodology as was used to calculate the amounts in the Summary Compensation Table on page 39 and by adding the $14,380 cost of medical and health benefits that the Company attributed to Mr. Roche in 2018 through Company-sponsored benefit plans; this amount was added in order to provide a like comparison to the elements of compensation included for the median employee. In accordance with SEC rules, we have used estimates and assumptions, as described above, in calculating the pay ratio reported above. The estimates and assumptions that we use may differ from estimates and assumptions used by other companies, including companies in our compensation peer group described above. •
