I suspect the second and third of these announcements are to fill the vacuum created by the first, but can anyone shed light on what "vacuum" is the impetus for the first? (more bluntly, who is leaving or retiring?)

By the way, all were very nice young men when I knew them and it's great to see them advance.

1) Alexander W. Masetti has been appointed vice president, Continuous Improvement, responsible for expanding and institutionalizing Air Products' overall continuous improvement activity, including capabilities such as Six Sigma and Lean.

2) Wilbur W. Mok has been appointed vice president, North America Tonnage Gases, succeeding Masetti. He will be responsible for leading, directing and growing the North America Tonnage Gases business for existing pipeline, franchise and on-site offerings and business relationships.

3) Michael A. Olivares has been appointed vice president, International. An expansion of his current role as vice president, Latin America/South Africa, he now will have responsibility for the continued growth and profitability of all of Air Products' major international joint ventures and partnerships.
