CYS Investments, Inc. (“CYS”) is a Maryland corporation founded in 2006.

CYS Common Stock, Series A Preferred Stock, and Series B Preferred Stock trade on the New York Stock Exchange (“NYSE”) under the symbols CYS, CYS PrA, and CYS PrB, respectively. We have been a publicly listed company since June 2009.

CYS offices are in Waltham, Massachusetts and New York City. We have 16 employees.

Our goal is to provide consistent risk-adjusted returns to our investors through a combination of dividends and capital appreciation.

We primarily invest on a leveraged basis in residential mortgage-backed securities whose principal and interest are guaranteed by a government agency or a government-sponsored entity (“Agency RMBS”). Our Agency RMBS are collateralized by adjustable-rate mortgage loans (“ARMs”) with monthly resetting interest rates, hybrid ARMs with initially fixed coupon rates (typically three, five seven or ten years) and thereafter resetting at regular intervals, or fixed rate mortgage loans. CYS’s income is primarily generated from the difference (the “net spread”) between the interest income we earn on our investments and the cost of our borrowings and hedging. Please see our reports on Form 10-K and Form 10-Q filed with the Securities and Exchange Commission ( for a more detailed description of our investment portfolio, our investment, borrowing and hedging strategies, and the associated risks. We have elected to be taxed as a real estate investment trust, or REIT, for federal income tax purposes.
