(1)	Under the Alleghany Corporation 2005 Directors' Stock Plan, 2010 Directors' Stock Plan and 2015 Directors' Stock Plan, when the registrant pays a cash dividend on its common stock, each director holding restricted stock units ("RSUs") awarded under such plan(s) is credited with a corresponding dividend on his or her RSUs in the form of additional RSUs. These shares represent RSUs received as dividends in connection with a special cash dividend of $10.00 per share of common stock paid on March 15, 2018. These additional RSUs will vest on the same schedule as the unvested RSUs to which they relate.
(2)	Grant of 234 shares of restricted stock for no cash consideration under the Alleghany Corporation 2015 Directors' Stock Plan, reflecting such number of restricted stock shares equal to $140,000 (as determined by the Board in accordance with the plan) divided by the average of the closing sales prices of the common stock on the 30 consecutive trading days preceding the grant date as reported by the NYSE.
