| Factors Affecting Performance [Text Block] | How did the Fund perform last year and what affected its performance? During the reporting period, the Fund generated a positive total return while paying out consistent monthly dividends. The Fund returned a total return of 7.83% compared to the total return of 10.55% of the U.S. Aggregate Bond Index. The main driver of the returns were the short duration treasury holdings, and debit spreads that capture premium from a combination of dividends and growth of underlying assets. What Factors Influenced Performance? The main factors influencing the growth of the underlying assets can be attributed to a strong environment for equity markets and stabilization of interest rates. Positioning of the Fund A large portion of the Fund is held in shorter-term U.S. treasuries which provides stable distributions and share price. The current maturities of the bond positions are approximately two years or less. The rest of the Fund analyzes fundamental, economic, and technical trends and attempts to generate returns by delivering both extrinsic time premiums and upside capture of underlying indexes. |
