 involving the credit of an issuer possessing taxing power and are payable from such issuer’s general revenues and not from any particular source. Limited obligation bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source or annual revenues. Tax-exempt private activity bonds and industrial development bonds generally are also revenue bonds and thus are not payable from the issuer’s general revenues. The credit and quality of private activity bonds and industrial development bonds are usually related to the credit of the corporate user of the facilities. Payment of interest on and repayment of principal of such bonds is the responsibility of the user and any guarantor. The Fund does not expect to be eligible to pass through to shareholders the tax-exempt character of interest earned on municipal bonds. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in industrial development bonds. A fund that may invest in municipal bonds may invest in pre-refunded municipal bonds. Pre-refunded municipal bonds are tax-exempt bonds that have been refunded to a call date prior to the final maturity of principal, or, in the case of pre-refunded municipal bonds commonly referred to as “escrowed-to-maturity bonds,” to the final maturity of principal, and remain outstanding in the municipal market. The payment of principal and interest of the pre-refunded municipal bonds held by the Fund is funded from securities in a designated escrow account that holds U.S. Treasury securities or other obligations of the U.S. Government (including its agencies and instrumentalities (“Agency Securities”)). Interest payments on pre-refunded municipal bonds issued on or prior to December 31, 2017 are exempt from federal income tax; interest payments on pre-refunded municipal bonds issued after December 31, 2017 are not exempt from federal income tax. As the payment of principal and interest is generated from securities held in an escrow account established by the municipality and an independent escrow agent, the pledge of the municipality has been fulfilled and the original pledge of revenue by the municipality is no longer in place. Pre-refunded municipal bonds may bear an AAA/Aaa rating (for example, if re-rated by a rating service or, if not re-rated, determined by PIMCO to be of comparable quality) because they are backed by U.S. Treasury securities or Agency Securities. For the avoidance of any doubt, PIMCO’s determination of issuer credit rating will be used for compliance with
