This Amendment 1 to Schedule 13D relates to the Common Stock, no par value (the "Common Stock"), of American Medical Security Group, Inc., a Wisconsin corporation (the "Company"), 3100 AMS Blvd., Green Bay, WI 54313. Item 3: Source and Amount of Funds or Other Consideration. Item 3 of the Schedule 13D is hereby amended by replacing the paragraph therein with the following paragraph: "An aggregate of $5,655,099.13 (excluding commissions, if any) was paid in a series of transactions pursuant to which Caxton International acquired the Common Stock owned by it. All of the foregoing amounts were paid out of Caxton International's working capital." Item 5: Interest in Securities of the Issuer. The first paragraph of subparagraph (a) of Item 5 of the Schedule 13D is hereby amended by replacing said paragraph with the following paragraph: "(a) Caxton International beneficially owns 1,028,800 shares of Common Stock, representing approximately 6.6% of the total shares of Common Stock issued and outstanding. The increase in beneficial ownership from the date of the original Schedule 13D filed December 9, 1999, is a result of Caxton International's acquisition of additional Common Stock as set forth in Schedule 2 and a decrease in the total Common Stock outstanding due to the Company's repurchase of 1.1 million shares of Common Stock in the fourth quarter of 1999, as described in the Company's Form 10-K dated March 15, 2000." Subparagraph (c) of Item 5 of the Schedule 13D is hereby amended by adding the following sentence: "See Schedule 2 for disclosure of (1) the date, (2) the price and (3) the amount of shares purchased or sold by Caxton International during the past 60 days." After reasonable inquiry and to the best of the undersigneds' knowledge and belief, the undersigned certify that the information set forth in this statement is true, complete and correct.
