In addition, this summary is limited to IP common stockholders who hold their shares of IP common stock as a capital asset. Neither IP nor Sylvamo provides tax advice to its stockholders. The example provided below is illustrative and is being provided pursuant to Section 6045B of the Code and as a convenience to stockholders and their tax advisors.
