General Description of Registrant [Abstract]
Risk Factors [Table Text Block]	Item 1A. Risk Factors In addition to the other information set forth in this Report, you should consider carefully the factors discussed below, as well as in Part I “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022 filed on November 17, 2022, which could materially affect our business, financial condition and/or operating results. The risks described below, as well as in our Annual Report on Form 10-K are not the only risks facing PennantPark Floating Rate Capital Ltd. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition and/or operating results. Legislation enacted in 2018 allows us to incur additional leverage. A BDC has historically been able to issue “senior securities,” including borrowing money from banks or other financial institutions, only in amounts such that its asset coverage, as defined in Section 61(a)(2) of the 1940 Act, equals at least 200% after such incurrence or issuance. In March 2018, the Consolidated Appropriations Act of 2018 (which includes the SBCAA) was enacted which amended the 1940 Act to decrease this percentage from 200% (i.e., $1 of debt outstanding for each $1 of equity) to 150% (i.e., $2 of debt outstanding for each $1 of equity) for a BDC that has received either stockholder approval or approval of a “required majority” (as defined in Section 57(o) of the 1940 Act) of its board of directors of the application of such lower asset coverage ratio to the BDC. On April 5, 2018, our board of directors approved such reduction. As of April 5, 2019, we are able to incur additional indebtedness so long as we comply with the applicable disclosure requirement, which may increase the risk of investing in us. Under the 200% minimum asset coverage ratio, we were permitted to borrow up to one dollar for investment purposes for every one dollar of investor equity and, under the 150% minimum asset coverage ratio, we are permitted to borrow up to two dollars for investment purposes for every one dollar of investor equity. In other words, Section 61(a)(2) of the 1940 Act permits BDCs to potentially increase their debt-to-equity ratio from a maximum of 1-to-1 to a maximum of 2-to-1. In addition, since our base management fee is determined and payable based upon our average adjusted gross assets, which includes any borrowings for investment purposes, our base management fee expense may increase if we incur additional leverage. Because we intend to distribute substantially all of our income to our stockholders to maintain our ability to be subject to tax as a RIC, we may need to raise additional capital to finance our growth. If funds are not available to us, we may need to curtail new investments, and our common stock value could decline. In connection with satisfying the requirements to be subject to tax as a RIC for federal income tax purposes, we intend to distribute to our stockholders substantially all of our investment company taxable income and net capital gains each taxable year. However, we may retain all or a portion of our net capital gains and incur applicable income taxes with respect thereto and elect to treat such retained net capital gains as deemed dividend distributions to our stockholders. As noted above, on April 5, 2018, our board of directors, including a “required majority” (as such term is defined in Section 57(o) of the 1940 Act), approved a reduction of our asset coverage ratio from 200% to 150%. As a result, as of April 5, 2019, the asset coverage requirement applicable to us for senior securities was reduced from 200% (i.e., $1 of debt outstanding for each $1 of equity) to 150% (i.e., $2 of debt outstanding for each $1 of equity). If we incur additional indebtedness under this provision, the risk of investing in us will increase. If the value of our assets declines, we may be unable to satisfy this asset coverage test. If that happens, we may be required to sell a portion of our investments or sell additional common stock and, depending on the nature of our leverage, to repay a portion of our indebtedness at a time when such sales and repayments may be disadvantageous. In addition, the issuance of additional securities could dilute the percentage ownership of our current stockholders in us. We are partially dependent on our subsidiary, Funding I, for cash distributions to enable us to meet the distribution requirements in order to permit us to be subject to tax as a RIC. In this regard, Funding I is limited by its covenants from making certain distributions to us that may be necessary to fulfill our requirements to be subject to tax as a RIC. In such case, we would need to request a waiver of these covenants’ restrictions for Funding I to make certain distributions to enable us to be subject to tax as a RIC. We cannot assure you that Funding I will be granted such a waiver, and if Funding I is unable to obtain a waiver, compliance with the covenants may cause us to incur a corporate-level income tax. If we incur additional debt, it could increase the risk of investing in our shares. We have indebtedness outstanding pursuant to our Credit Facility, 2023 Notes, 2026 Notes and the 2031 Asset-Backed Debt and expect in the future to borrow additional amounts under our Credit Facility or other debt securities, subject to market availability, and, may increase the size of our Credit Facility. We cannot assure you that our leverage will remain at current levels. The amount of leverage that we employ will depend upon our assessment of the market and other factors at the time of any proposed borrowing. Lenders have fixed dollar claims on our assets that are superior to the claims of our common stockholders or preferred stockholders, if any, and we have granted a security interest in Funding I’s assets in connection with our Credit Facility borrowings. In the case of a liquidation event, those lenders would receive proceeds before our stockholders. Any future debt issuance will increase our leverage and may be subordinate to our Credit Facility. In addition, borrowings or debt issuances, also known as leverage, magnify the potential for loss or gain on amounts invested and, therefore, increase the risks associated with investing in our securities. Leverage is generally considered a speculative investment technique. If the value of our assets decreases, then the use of leverage would cause the net asset value attributable to our common stock to decline more than it otherwise would have had we not utilized leverage. Similarly, any decrease in our revenue would cause our net income to decline more than it would have had we not borrowed funds and could negatively affect our ability to make distributions on our common or preferred stock. Our ability to service any debt that we incur depends largely on our financial performance and is subject to prevailing economic conditions and competitive pressures. As noted above, on April 5, 2018, our board of directors, including a “required majority” (as such term is defined in Section 57(o) of the 1940 Act), approved a reduction of our asset coverage ratio. As a result, as of April 5, 2019, the asset coverage requirement applicable to us for senior securities was reduced from 200% to 150%. As of such date, we are able to incur additional indebtedness so long as we comply with the applicable disclosure requirements, which may increase the risk of investing in us.

Investing in Shares Risk
