Most of Morgan Stanley's asset management activities were principally conducted under the Morgan Stanley and Van Kampen brands.
On October 19, 2009, Morgan Stanley announced that Van Kampen would be sold to Invesco for $1.5 billion. After the acquisition, Invesco ceased using the Van Kampen name except in relation to its component mutual funds.
