SEC Form 424B3 filed by Blackrock Corporate High Yield Fund Inc.

Purchase securities of other investment companies, except to the extent that such purchases are permitted by applicable law.

Mortgage, pledge, hypothecate or in any manner transfer, as security for indebtedness, any securities owned or held by the Fund except as may be necessary in connection with borrowings mentioned in investment restriction (3) above or except as may be necessary in connection with transactions described under “Description of the Fund—Investment Objectives and Principal Investment Policies—Other Investment Strategies” above.

Purchase any securities on margin, except that the Fund may obtain such short term credit as may be necessary for the clearance of purchases and sales of portfolio securities (the deposit or payment by the Fund of initial or variation margin in connection with financial futures contracts and options thereon is not considered the purchase of a security on margin).

Change its policy of investing, under normal circumstances, at least 80% of the value of its assets in high yield securities of corporate issuers and derivatives that provide investment exposure to such securities or to one or more market risk factors associated with such securities, unless the Fund provides its stockholders with at least 60 days’ prior written notice of such change. For these purposes, “assets” means net assets, including assets acquired from the sale of preferred stock, plus the amount of any borrowings for investment purposes.
