Note: Fastenal has had three CEOs recently. Willard Oberton, who had been CEO since 2002 and chairman since April 2014, retired as CEO on Dec. 31, 2014. He was succeeded as CEO by the company's chief operating officer, Leland Hein.

But Oberton returned as interim president and CEO on July 22 when Hein resigned as CEO and resumed his chief operating role.

In October, the company announced that Dan Florness, chief financial officer, would become CEO effective Jan. 1.

The proxy statement released on Wednesday disclosed the compensation numbers for each executive but offered little disclosure on the reasons behind the executive moves.

Oberton remained chairman of the board throughout the CEO shuffling, but his temporarily reduced role also came with a lower salary and his overall compensation from 2015 was down 58 percent from the previous year, in part from the lower salary during the year and a lower annual bonus.
