公司资本充足是指股东实缴的出资与公司的经营规模相适应，以确保公司有充足的资本应对经营风险、偿付到期债务，与之相匹配的法律规范就是公司资本充足制度。近年来，随着市场经济的发展，立法机关改变了法定资本制的立场，在司法实践中，公司资本充足制度也呈现出渐见宽松的趋势。

一、《公司法》多次修改公司资本制度，大幅放宽了资本管制

1993年12月颁行的《公司法》采取了严格的法定资本制度。

2005年10月修订的《公司法》在保持法定资本制度的同时，降低了设立公司的资本门槛，将严格的法定资本制度修改为法定资本分期缴纳的资本制度。

2013年12月修正的《公司法》大幅修改了公司资本制度，将实缴登记制改为认缴登记制（特殊行业除外），取消了注册资本的最低限额、分期认缴期限、首付出资比例及出资财产形式的限制等规定，改由股东在公司章程中自行约定，基本完成从法定资本制到授权资本制的转变。

2018年10月修改的《公司法》增加了允许上市公司回购本公司股份的情形，并实际上赋予上市公司回购股份的自主决定权（“上市公司为维护公司价值及股东权益所必需”），还简化了股份回购的决策程序，提高了公司持有本公司股份的数额上限，延长了公司持有所回购股份的期限。

In Momentive Performance Materials Inc. v. BOKF, NA (In re MPM Silicones, L.L.C.), 874 F.3d 787 (2d Cir. 2017), cert. denied, 138 S. Ct. 2653 (2018), the U.S. Court of Appeals for the Second Circuit affirmed a number of lower court rulings on hot-button bankruptcy issues, including allowance (or, in this case, denial) of a claim for a "make-whole" premium and contractual subordination of junior notes.

The ability of a bankruptcy trustee to avoid fraudulent or preferential transfers is a fundamental part of U.S. bankruptcy law. However, when an otherwise avoidable transfer by a U.S. entity takes place outside the U.S. to a non-U.S. transferee—as is increasingly common in the global economy—courts disagree as to whether the Bankruptcy Code’s avoidance provisions apply extraterritorially to avoid the transfer and recover the transferred assets. Several bankruptcy and appellate courts have addressed this issue in recent years, with inconsistent results.

In In re Tribune Co. Fraudulent Conveyance Litig., 2019 WL 1771786 (S.D.N.Y. Apr. 23, 2019), the U.S. District Court for the Southern District of New York denied a litigation trustee’s motion to amend a complaint seeking to avoid alleged fraudulent transfers made to selling shareholders as part of a 2007 leveraged buyout ("LBO") of the Tribune Co. ("Tribune"), ruling that the safe harbor in section 546(e) of the Bankruptcy Code continues to bar such claims notwithstanding the U.S. Supreme Court’s February 2018 decision in Merit Management Group v. FTI Consulting.

On January 10, 2019, the Italian government approved the Code for Distress and Insolvency (Codice della Crisi d’Impresa e dell’Insolvenza—the "CDI" ) as part of Legislative Decree No. 14 of 2019, to replace the Italian Bankruptcy Law of 1942. With certain exceptions, the CDI will enter into force on August 14, 2020, unless amended by the Italian Parliament prior to the effective date.

For more than a century, courts in England and Wales have refused to recognize or enforce foreign court judgments or proceedings that discharge or compromise debts governed by English law. In accordance with a rule (the "Gibbs Rule") stated in an 1890 decision by the English Court of Appeal, creditors holding debt governed by English law may still sue to recover the full amount of their debts in England even if such debts have been discharged or modified in connection with a non-U.K.

In In re Argon Credit, LLC, 2019 WL 169315 (Bankr. N.D. Ill. Jan. 10, 2019), the U.S. Bankruptcy Court for the Northern District of Illinois ruled that, in accordance with section 510(a) of the Bankruptcy Code, a standby clause in a subordination agreement prevented a subordinated lender from conducting discovery concerning the senior lender’s claims.

In December 2018, at its 54th session in Vienna, Working Group V (Insolvency Law) of the United Nations Commission on International Trade Law (UNCITRAL) discussed revisions to its Enterprise Group Insolvency: Draft Model Law (the "EGI Model Law") as well as the EGI Model Law’s Guide to Enactment.

U.S. courts have a long-standing tradition of recognizing or enforcing the laws and court rulings of other nations as an exercise of international "comity." Prior to the enactment of chapter 15 of the Bankruptcy Code in 2005, the procedure for obtaining comity from a U.S. court in cases involving a foreign bankruptcy or insolvency case was haphazard and unpredictable. A ruling recently handed down by the U.S. District Court for the Northern District of Illinois indicates that the enactment of chapter 15 was a game changer in this context. In Halo Creative & Design Ltd. v.

In Tanguy v. West (In re Davis), 2018 WL 4232063 (5th Cir. Sept. 5, 2018), the U.S. Court of Appeals for the Fifth Circuit revisited the circumstances under which section 363(m) of the Bankruptcy Code moots an appeal of a bankruptcy court’s order approving a sale of assets. The Fifth Circuit reaffirmed its adherence to the majority rule on the issue, ruling that, absent evidence that the purchaser did not acquire the property in good faith, the challengers’ failure to obtain a stay pending appeal moots any appeal of a sale order.
