NORTH AMERICAN SENIOR FLOATING RATE FUND, INC.
REPURCHASE OFFER DOCUMENT
1. The Offer. North American (the "Fund") is offering (the "Offer") to
----------
repurchase for cash up to ten (10%) of its issued and outstanding shares
("Shares") at a price equal to the net asset value per share ("NAV") as of
the close of business on the New York Stock Exchange on the Repurchase
Pricing Date (defined below) upon the terms and conditions set forth herein.
The purpose of the Offer is to provide liquidity to shareholders because no
secondary market exists for the Shares. The Offer is not conditioned upon
the tender for repurchase of any minimum number of Shares.
2. Net Asset Value. The NAV of the Funds on November 13, 1998 was $9.98 per
----------------
Share. The NAV can fluctuate. Please call North American at 1-800-872-8037
for current price information. The Fund's shares are not traded on any
organized market.
3. Repurchase Request Deadline. All tenders of Shares for repurchase must be
----------------------------
received in proper form by the Fund on or before 4:00 p.m. Eastern time, on
November 30, 1998.
4. Repurchase Pricing Date. The NAV for the repurchase will be determined on
------------------------
November 30, 1998.
5. Payment for Shares Repurchased. The Fund expects to make payment for all
-------------------------------
shares repurchased the day following the Repurchase Pricing Date; in any
event, the Fund will pay repurchase proceeds within 5 business days or 7
calendar days (whichever is sooner) after the Repurchase Pricing Date. The
Fund will not charge a repurchase fee.
6. Increase in Number of Shares Repurchased: Pro Rata Repurchases. If
---------------------------------------------------------------
shareholders tender for repurchase more than 10% of the Shares, the Fund may
(but is not obligated to) repurchase an additional two percent (2%) of the
shares. If the Fund determines not to repurchase the additional 2%, or if
shareholders tender an amount exceeding 12% of the Shares, the Fund will
repurchase shares tendered on a pro rata basis.
There can be no assurance that the Fund will be able to repurchase all
shares that you have tendered, even if you tender all shares held in your
account. In the event of an oversubscribed Offer, you may be unable to
liquidate some or all of your investment at net asset value. You may have to
wait until a later month to tender shares that the Fund is unable to
repurchase, and you would be subject to the risk of net asset value
fluctuations during this time period.
7. Withdrawal of Shares to be Repurchased. Tenders of shares may be withdrawn
---------------------------------------
or modified at any time prior to 4:00 p.m., Eastern Time, on November 30,
1998.
<PAGE>
8. Suspension or Postponement of Repurchase Offer. The Fund may suspend or
-----------------------------------------------
postpone a Repurchase Offer in limited circumstances, and only by vote of a
majority of the Board of Directors, including a majority of the independent
Directors. These circumstances are limited and include the following:
(a) if the Repurchase would cause the Fund to lose its status as a
regulated investment company under Subchapter M of the Internal Revenue
Code;
(b) for any period during which an emergency exists as a result of which is
not reasonably practicable for the Fund to dispose of securities it
owns or to determine the value of the Fund's net assets;
(c) for any other periods that the Securities and Exchange Commission
permits by order for the protection of shareholders;
(d) if the shares are listed on a national securities exchange or quoted in
an inter-dealer quotation system of a national securities association
(e.g., NASDAQ) and the Repurchase would cause the shares to lose that
status; or
(e) during any period in which any market on which the shares are
principally traded is closed, or during any period in which trading on
the market is restricted.
You will be notified if the Fund suspends or postpones the Offer. If the Fund
renews the Offer after a suspension or postponement, you will be sent a new
notification.
Tax Consequences. Shareholders should consult their tax advisors regarding the
- -----------------
specific tax consequences, including state and local tax consequences, of
participating in the repurchase. A tender of shares pursuant to the repurchase
offer will be treated as a taxable sale of the Shares.
The Fund intends to take the position that tendering shareholders will qualify
for sale or exchange treatment. If the transaction is treated as a sale or
exchange for tax purposes, any gain or loss recognized would be treated as a
capital gain or loss by shareholders that hold their Shares as a capital asset.
* * * * *
Neither the Fund nor its Board of Directors makes any recommendation to any
shareholder as to whether to tender or refrain from tendering shares. Each
shareholder must make an independent decision whether to tender Shares and, if
so, how many Shares to tender.
No person has been authorized to make any recommendation on behalf of the Fund
as to whether shareholders should tender Shares pursuant to this Offer. No
person has been authorized to give any information or to make any
representations in connection with the Offer other than those contained herein
or in the Repurchase Procedures. If given or made, such recommendation and such
information and representation may not be relied upon as having been authorized
by the Fund.
For per share net asset value and other information, or for a copy of the Fund's
prospectus, contact your financial consultant or call North American Funds
at 1-800-872-8037.
