 外刊例句 

Athena, America’s largest boutique lender, requires art worth about $2m to secure its minimum loan of $1m. At Bank of America and other private banks, the minimum loan is closer to $5m. Both accept only works by well-known artists as collateral, since they are the only ones with reliable longevity. Thus art-secured loans are less risky than many believe, says Arturo Cifuentes of Columbia Business School.

美国最大的专门贷款机构Athena，要求用价值200万美元左右的艺术品来担保最低100万美元的贷款。在美国银行和其他私人银行，最低贷款额接近500万美元。所有这些机构都只接受知名艺术家的作品作为抵押物，因为只有这些作品才具有长期稳定的价值。哥伦比亚大学商学院的阿图罗·西丰特斯说，艺术品抵押贷款的风险比许多人认为的要低。
