Table of Contents CITIZENS, INC. AND CONSOLIDATED SUBSIDIARIES policies are marketed. Venezuela, for example, is continuing to experience civil unrest due to local demonstrations against crime, corruption and soaring inflation. See "Item 1A. Risk Factors" for additional information. The following table sets forth our direct premiums by state from our domestic business for the periods indicated. We discontinued new sales of our non-Home Service domestic products in 2017 while we reevaluate our domestic life strategy; therefore, the majority of the premium recorded in 2017 and all of the premium in 2018 are related to renewal business. Net Investment Income. Net investment income has increased due to continued growth in average invested assets even though the annual yield has decreased sixteen basis points in this segment from 2017. We also noted that current securities sales, calls and maturities had an average coupon of 5.84% and new securities that we are currently purchasing have an average coupon of 3.66%. A portion of this decrease in yield is also related to repositioning our portfolio into more diversified holdings and maturities as part of our investment management strategy. See the Investment section below for more detailed information. Realized Investment Losses, Net.
