 PIMCO will, on behalf of the Fund, make reasonable determinations as to the appropriate industry classification to assign to each security or instrument in which the Fund invests. The definition of what constitutes a particular “industry” is an evolving one, particularly for industries or sectors within industries that are new or are undergoing rapid development. Some securities could reasonably fall within more than one industry category. The Fund’s industry concentration policy does not preclude it from focusing investments in issuers in a group of related industrial sectors (such as different types of utilities). For purposes of the industry concentration policy, a foreign government is considered to be an industry, although currency positions are not considered to be an investment in a foreign government for these purposes. Mortgage-related or ABS that are issued or guaranteed as to principal or interest by the U.S. Government or its agencies or instrumentalities are not subject to the Fund’s industry concentration policy, by virtue of the exclusion from that test available to all U.S. Government securities. Similarly, tax-exempt municipal bonds issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies and authorities are not subject to the Fund’s industry concentration policy. To the extent that an underlying investment company in which the Fund invests has adopted a policy to concentrate its investments in a particular industry, the Fund will, to the extent applicable, take such underlying investment company’s concentration policy into consideration for purposes of the Fund’s own industry concentration policy.

The Fund may not change its policy to invest at least 80% of its total assets in a combination of corporate debt obligations of varying maturities, other corporate income-producing securities, and income-producing securities of non-corporate issuers unless it provides shareholders with at least 60 days’ written notice of such change. The Fund interprets its policies with respect to borrowing and lending to permit such activities as may be lawful for the Fund, to the full extent permitted by the 1940 Act or by exemption from the provisions therefrom pursuant to exemptive order of the SEC. It is a condition of the issuance of the Preferred Shares that they be issued with a credit quality rating of “Aaa” from Moody’s. In order to obtain and maintain the required rating, the Fund will be required to comply with investment quality, diversification and other guidelines established by Moody’s. Such guidelines will likely be more restrictive than the restrictions set forth above. The Fund does not anticipate that such guidelines would have a material adverse effect on the holders of the Common
