JIBSX Investment Objective and Strategy
Johnson Institutional Core Bond Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Johnson Mutual Funds Trust.
Investment objective
A high level of income over the long term consistent with preservation of capital.
Principal investment strategy
The funds strategy seeks to provide a diversified portfolio of investment grade bonds with aggregate risk, return, and income characteristics that are similar to those of broad bond market indices. Under normal market conditions, the fund invests at least 80% of its net assets, plus any amounts for borrowing, in a broad range of investment grade fixed income securities, including bonds, notes, domestic and foreign corporate and government securities, government agency securities, mortgage-backed securities, collateralized mortgage obligations, asset-backed securities, municipal securities, and short-term obligations. The fund does not limit itself to securities of a particular maturity range but will normally seek to maintain a dollar weighted average duration between 4 to 8 years. Duration is a measure of the expected life of a fixed income security that is used to determine the sensitivity of a securitys price to changes in interest rates.
For example, the value of a portfolio of fixed income securities with an average duration of one year would generally be expected to decline by approximately 1% if interest rates rose by 1%.
