CYS Investments, Inc. is a specialty finance company created with the objective of achieving consistent risk-adjusted investment income. The Company invests in Agency residential mortgage-backed securities (RMBS) collateralized by fixed rate single-family residential mortgage loans (typically 15, 20 or 30 years), adjustable-rate mortgage loans (ARMs), which typically have coupon rates that reset monthly, or hybrid ARMs, which typically have a coupon rate that is fixed for an initial period (typically three, five, seven or 10 years) and thereafter resets at regular intervals. In addition, its investment guidelines permit investments in collateralized mortgage obligations issued by a government agency or government-sponsored entity that are collateralized by Agency RMBS (CMOs), although the Company had not invested in any CMOs as of December 31, 2011.
