BNSF Railway, a railroad operator based in Fort Worth, Texas, on Monday said Chief Financial Officer Tom Hund will retire during the first quarter next year. The company, owned by Warren Buffett’s Berkshire Hathaway Inc. since early 2010, said Julie Piggott, currently BNSF’s controller and vice president of planning and studies, will succeed Mr. Hund. Mr. Hund has been CFO of BNSF since 1999; Ms. Piggot joined BNSF in 1991 and has been in her current role since 2009. Compensation information for the executives wasn’t disclosed.<br /><br />KBR Inc., a global engineering, construction and services company based in Houston, said Brian Ferraioli was named CFO. He was most recently CFO for six years at Shaw Group, which was acquired early this year by Chicago Bridge & Iron Co. Mr. Ferraioli will receive a salary of $650,000, according to a regulatory filing. Former KBR CFO Susan Carter resigned in September to take the same post at Ingersoll-Rand PLC to succeed its retiring CFO. Ms. Carter received total compensation valued at $2.4 million last year, including a $593,131 salary and equity awards valued at a combined $1.4 million, according to KBR’s most recent proxy statement.<br /><br />Write to Maxwell Murphy at Maxwell.Murphy@wsj.com, and follow him on Twitter @KMaxwellMurphy.
