State Street Boston Corp. created a sales position in its investment  management arm to focus entirely on pension plan clients from midsized   companies.   
The Boston-based bank said Monday that Michael C. McNabb, a managing  director at State Street Global Advisors, will work exclusively on sales to   pension plans with assets under management ranging from $26 million to $125   million.     
  
Previously, State Street executives had not exclusively focused on such  a target group, but Mr. McNabb's position was created to pick up prospects   that size.   
"It's a segment of the market that is increasingly important. It seems  desirable to have somebody with experience and knowledge focusing on this   sector exclusively," a State Street spokesman said.   
  
Previously, Mr. McNabb directed sales for State Street Global Advisors'  trust and investments division, which manages over $8 billion for wealthy   individuals, endowments, and foundations. State Street Global Advisors has   a total of $292 billion in assets under management.     
To take Mr. McNabb's place in the trust department, the bank promoted  J.H. "Jay" Cromarty. Mr. Cromarty, who joined State Street last year, had   been managing director in its office of the fiduciary adviser, overseeing   $2.5 billion in retirement assets.
