CUSIP No. 588056101 ITEM 1. SECURITY AND ISSUER: This statement on Schedule 13D relates to Common Shares of Beneficial Interest, $1.00 par value (the "Shares"), of Mercer International Inc., a Washington corporation ("Mercer"). The principal executive offices of Mercer are located at 14900 Interurban Avenue South, Suite 282, Seattle, WA 98168. ITEM 2. IDENTITY AND BACKGROUND: (a) This statement on Schedule 13D is filed on behalf of Peter R. Kellogg and IAT Reinsurance Company Ltd. ("IAT"). Mr. Kellogg is the sole owner of IAT's voting stock, is a member of IAT's board of directors, and is the President and CEO of IAT. A joint filing agreement of Mr. Kellogg and IAT is attached hereto as Exhibit A. (b)-(c), (f) Mr. Kellogg is an American citizen and a private investor. IAT is a reinsurance company incorporated in Bermuda. Mr. Kellogg's business address is 120 Broadway, 6th floor, New York, NY 10271, and IAT's business address is 48 Wall Street, New York, NY 10005. (d)-(e) During the last five years, neither IAT, Mr. Kellogg, nor, to their knowledge, any of the directors or executive officers of IAT has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION: This Schedule 13D relates to 2,328,122 Shares of Mercer held by IAT and its wholly-owned subsidiaries, 136,900 Shares of Mercer held by two partnerships and a foundation which are controlled by Mr. Kellogg, and 1,645,161 issuable upon conversion of $12,750,000 of 8.5% convertible senior subordinated notes held by IAT and its subsidiaries. The convertible notes are convertible into Shares at any time prior to the maturity date of October 15, 2010 at a conversion price of $7.75 per share, subject to certain adjustments. The source of funds for the purchases of Shares was the working capital of IAT and its wholly-owned subsidiaries, the personal funds of Mr. Kellogg, and the funds of the foundation and the partnerships administered by Mr. Kellogg. ITEM 4. PURPOSE OF TRANSACTION: The Shares of Mercer were acquired for investment purposes in the ordinary course of business by IAT and its wholly-owned subsidiaries, and by the foundation and the partnerships controlled by Mr. Kellogg and were not acquired with the purpose or effect of changing or influencing control of Mercer. Mr. Kellogg and IAT review their holdings of Mercer on an ongoing basis. Depending on such review and on various factors, including, without limitation, the price of the shares, stock market conditions, and business prospects of Mercer, Mr. CUSIP No. 588056101 Kellogg and IAT reserve the right to make additional purchases or sales of the Shares of Mercer in the future, although they have no present plans or proposals to do so. Any purchases may be effected directly or through one or more entities controlled or deemed to be controlled by Mr. Kellogg. Any purchases or sales may be in the open market, in a privately negotiated transaction or otherwise. Neither Mr. Kellogg nor IAT have any current plans or proposals which relate to or would result in any of the transactions or changes contemplated in Items 4(a) through 4(j) of Schedule 13D. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER: (a) and (b) This statement relates to 2,328,122 Shares of Mercer held by IAT and its wholly-owned subsidiaries, 136,900 Shares of Mercer held by two partnerships and a foundation which are controlled by Mr. Kellogg, and 1,645,161 issuable upon conversion of $12,750,000 of 8.5% convertible senior subordinated notes held by IAT and its subsidiaries. Based on Mercer's public filings, Mercer had 17,099,899 shares outstanding as of September 30, 2003, 2002. Therefore, the 4,107,583 Shares reported on this Schedule 13D represent 21.9% of Mercer's outstanding Shares as of the date of the event which triggered the filing of this Schedule 13D. Mr. Kellogg has sole dispositive and voting power with respect to the Shares of Mercer owned by IAT and its subsidiaries. By virtue of his position with IAT, Mr. Kellogg may be considered to indirectly beneficially own such Shares. Mr. Kellogg disclaims beneficial ownership of the Shares owned by IAT and its subsidiaries, and this statement should not be deemed to be an admission that Mr. Kellogg is a member of any "group" within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder. (c) On October 10, 2003, IAT purchased $12,750,000 of Mercer's 8.5% convertible senior subordinated notes. The convertible notes were issued directly by Mercer in a private placement. Other than as set forth in this paragraph, the reporting persons have not effected any transactions in any class of securities of Mercer during the 60 days prior to the date of the event which requires the filing of this Schedule 13D. (d) The non-voting stockholders of IAT have the right to participate in the receipt of dividends from, or proceeds from the sale of, the common shares held by them in accordance with their ownership interest in IAT. (e) Not Applicable ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER: Except as described in Item 5(d) above, to the best knowledge of Mr. Kellogg and IAT, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons enumerated in Item 2 or between such persons and any other person with respect to any securities of Mercer, including, but not limited to, transfer or voting of any of the shares, CUSIP No. 588056101 finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
