补充资料：大陆法上的浮动担保
大陆法上的浮动担保
【大陆法上的浮动担保】大陆法各国对浮动担保的态度不完全一致。少数拉丁美洲国家承认浮动担保，并制定了有关浮动担保的法律，这主要是英美在这些国家长期投资所促成的。其他大陆法国家大都不愿意承认把借款人的全部资产作为一个贷款人的担保物，让一个贷款人垄断担保权益的做法。现将一些国家有关法律简介如下:(l)意大利法。意大利法律规定，借款人可以其全部动产，包括现有的和将来取得的动产设定质权，但质权只有在贷款人取得占有时才能生效。(2)法国法。原先法国法规定在一家公司的现有和将来取得的财产上设定全面的浮动担保，并不授予债权人以担保物权，后来，法国立法逐渐允许出抵企业的固定资产与商誉，并允许在原料和制造过程中的产品上设定担保物权。(3)德国法。德国的法律不承认浮动担保是一种担保物权，但它以某种债权让与的方式来达到类似的目的。这类债权让与有披露让与和全面让与两种形式。披露让与是指借款人将一定数目的将来的应收款项让与给贷款银行，作为其贷款的担保。全面让与是指把借款人现有和将来的应收款项全部让与给贷款人，作为贷款的担保。 由于各国对浮动担保的法律有分歧，在国际性的借贷交易中就不可避免地引起法律冲突，但浮动担保的特点决定了它能够适应当代工商业融资的需要，特别是项目融资中，浮动担保最为适合于使用，因此，浮动担保在国际借贷业务中被广泛采用。
