Item 5.02.
Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Agreements of Certain Officers.
On April 23, 2018, Joseph H. Pyne, Chairman of the Board of Kirby Corporation, informed the Board of Directors of Kirby that he is retiring as executive Chairman of the Board, effective April 30, 2018.  He will continue as Chairman of the Board of Directors in a non-executive role.
In connection with his retirement, the independent directors of Kirby approved the payment to Mr. Pyne of a special one-time bonus of $15 million and acceleration of the vesting of unvested stock options covering 26,819 shares of Kirby common stock and 30,643 unvested shares of restricted stock held by Mr. Pyne.  Including a value of $3.1 million attributable to the noncash accelerated vesting of the equity awards, the compensation to Mr. Pyne will result in an $18.1 million, or approximately $0.30 per share, one-time nondeductible expense in the second quarter.  Stock options for 21,396 shares and 13,245 restricted stock units granted to Mr. Pyne in February 2018 will continue to vest in accordance with the terms of Kirby’s 2005 Stock and Incentive Plan.  Mr. Pyne will also be entitled to receive prorated payments of previously awarded incentive compensation in amounts and at times to be determined according to the terms of the plans under which the awards were made.  Mr. Pyne will no longer be compensated as an executive officer of Kirby.  In approving the compensation to Mr. Pyne, the independent directors considered a number of factors, including:
a noncompetition agreement with Mr. Pyne that extends for two years after he is no longer a director of Kirby
the importance to Kirby of having Mr. Pyne remain as Chairman of the Board of Kirby for the foreseeable future, in which capacity his extensive and invaluable knowledge of and stature in the marine transportation industry and knowledge of Kirby’s history, growth, long-term strategy, culture and operations will be available to Kirby’s management team when needed
Mr. Pyne’s role in implementing a long-term management succession plan developed by the independent directors of Kirby over a period of years, working together with Mr. Pyne, who made transitions in support of that plan from President and Chief Executive Officer to Chairman of the Board and Chief Executive Officer, then to executive Chairman of the Board and currently to nonexecutive Chairman of the Board
Mr. Pyne’s long and extraordinarily valuable service to Kirby in various executive capacities, including President, Chief Executive Officer and Chairman of the Board
