(Bloomberg News) Morgan Stanley, the bank whose shares have declined 44 percent this year, said in a filing yesterday that 580 of the 1,600 job cuts announced earlier this month will come from New York City.

"Rolling layoffs" began Dec. 15, the New York-based firm said in a submission to the state's Labor Department. Affected locations include 1221 Avenue of the Americas, 1 New York Plaza, 1585 Broadway and 750 Seventh Ave., the filing shows.

Chief Executive Officer James Gorman, 53, is grappling with Europe's debt crisis and concern that U.S. economic growth will slow, crimping demand for trading and investment-banking services. Financial firms have disclosed plans to eliminate more than 200,000 jobs globally this year.

Reductions will occur globally at all levels of the firm, Mark Lake, a company spokesman, said on Dec. 15. The 1,600 figure amounts to about 2.6 percent of the 62,648 employees Morgan Stanley had at the end of September. The decision to reduce staff came as "we conduct our year-end performance- management process and evaluate the right size of the franchise for 2012," Lake said at the time.
