investments may generally range in maturity from three to ten years and are made to U.S. and, to a limited extent, non-U.S. corporations, partnerships and other business entities which operate in various industries and geographical regions.
Under normal market conditions, we generally expect that at least 80% of the value of our managed assets, which means our net assets plus any borrowings for investment purposes, will be invested in Floating Rate Loans and other investments bearing a variable-rate of interest. We generally expect that first lien secured debt will represent at least 65% of our overall portfolio. We also generally expect to invest up to 35% of our overall portfolio opportunistically in other types of investments, including second lien secured debt and subordinated debt and, to a lesser extent, equity investments. We seek to create a diversified portfolio by generally targeting an investment size between $5 million and $30 million, on average, although we expect that this investment size will vary proportionately with the size of our capital base.
Our investment activity depends on many factors, including the amount of debt and equity capital available to middle-market companies, the level of merger and acquisition activity for such companies, the general economic environment and the competitive environment for the types of investments we make. We have used, and expect to continue to use, our debt capital, proceeds from the rotation of our portfolio and proceeds from public and private offerings of securities to finance our investment objectives.
Organization and Structure of PennantPark Floating Rate Capital Ltd.
PennantPark Floating Rate Capital Ltd., a Maryland corporation organized in October 2010, is a closed-end, externally managed, non-diversified investment company that has elected to be treated as a BDC under the 1940 Act. In addition, for federal income tax purposes we have elected to be treated, and intend to qualify annually, as a RIC under the Code.
Funding I, our wholly owned subsidiary and a special purpose entity, was organized in Delaware as a limited liability company in May 2011. We formed Funding I in order to establish the Prior Credit Facility. On August 12, 2021, we terminated the Prior Credit Facility, and Funding I, as borrower, entered into the Credit Facility, which provides the ability for Funding I to borrow up to $366 million (increased from $300 million in September 2022). The Credit Facility is secured by all of the assets of Funding I.
In May 2017, we and a subsidiary of Kemper Corporation (NYSE: KMPR), Trinity Universal Insurance Company, or Kemper, formed PSSL, an unconsolidated joint venture. PSSL invests primarily in middle-market and other corporate debt securities consistent with our strategy. PSSL was formed as a Delaware limited liability company.
In April 2019, our wholly owned subsidiary, the Securitization Issuer, was incorporated in the Cayman Islands as an exempted company with limited liability. We formed the Securitization Issuer in order to complete the Debt Securitization.
