It breaks out the 15-year fixed-rate agency MBS holdings by government-sponsored entity ('GSE'). This includes both Fannie Mae ( OTCQB:FNMA ) and Freddie Mac ( OTCQB:FMCC ) MBS. As of 9/30/2013, AGNC's Ginnie Mae holdings only accounted for 0.29% of the company's MBS portfolio. As such, Ginnie Mae fixed-rate agency MBS price movements are immaterial for projection purposes and thus excluded from this table and article. Table 8 further breaks out the 15-year fixed-rate agency MBS price movements into the various coupons on AGNC's books ranging from 2.5% - 4.5%. AGNC holds an immaterial balance of 15-year fixed-rate agency MBS over the 4.5% coupon and thus these specific coupons are excluded from Table 8 above. From the information portrayed in Table 8 above, a valuation gain (loss) can be calculated which is broken down by the various coupons. This valuation gain (loss) is performed in Table 10 later in the article.
