Kirby McInerney LLP is investigating potential claims against the Board of Directors of National Interstate Corporation (“National Interstate” or the “Company”) (NASDAQ: NATL) concerning the proposed acquisition of the Company by a wholly-owned subsidiary of American Financial Group, Inc. (“American Financial”) (NYSE: AFG). Under the terms of the tender offer, National Interstate shareholders would receive $28.00 in cash for each share of National Interstate owned. The investigation concerns possible breaches of fiduciary duties by the National Interstate Board of Directors in its process for considering the proposed transaction, including whether the Company is acting in the best interest of its shareholders, and whether the $28.00 per share proposed consideration adequately values National Interstate’s common stock. If you are a National Interstate shareholder and wish to obtain additional information, please contact J. Brandon Walker, Esq. by email at email@example.com, by telephone at (212) 699-1145 or (888) 529-4787, or by filling out this contact form. There is no cost or obligation to you.
