In addition to considering economic factors such as the effect of interest rates on the Funds investments, Aquila Investment Management LLC (the Manager) applies a bottom up approach in choosing investments. The Manager considers the individual characteristics of each potential investment in an income-producing security to determine if it is an attractive investment opportunity and consistent with the Funds investment policies. The Manager also employs a relative value analysis and fundamental credit research on potential investments in an effort to identify companies with attractive characteristics such as improving balance sheets, improving cash flow or interest coverage, improving earnings, hidden or unappreciated value, management quality, and/or strong business models. Within the parameters of the Funds specific investment policies, the Fund may invest without limit in foreign debt, including debt of emerging markets issuers. The Fund may also invest in subordinated securities and may hold cash or other short-term investments. Show less
