Annaly’s vice chairman, chief investment officer and COO Wellington Denahan-Norris said that during the quarter, in their portfolio they saw prepayment speeds increase slightly, they took advantage of market opportunities to harvest gains, and maintained a prudent level of leverage.
"After taking into account the effect of interest rate swaps, our portfolio of mortgage-backed securities and Agency debentures was comprised of 42% floating-rate, 9% adjustable-rate and 49% fixed-rate assets," added Norris.
