Arlington Asset Investment Corp. is a principal investment firm that acquires and holds primarily mortgage-related assets and holds certain other assets. The Company acquires residential mortgage-backed securities (MBS), either issued by the United States Government agencies or guaranteed as to principal and interest by the United States Government agencies or United States government-sponsored entities (agency-backed MBS). The Company acquires and holds non-agency, or private-label MBS. Private-label MBS are MBS that are not issued or guaranteed by a United States Government agency or a government-sponsored entity (GSE), such as Fannie Mae or Freddie Mac. The private-label MBS in which the Company invests are generally backed by a pool of single-family residential mortgage loans. The Company manages its portfolio of mortgage holdings with the goal of obtaining a high risk-adjusted return on capital.
