Business Groups and Tunneling: Evidence from Private Securities Offerings by Korean Chaebols

Using a comprehensive sample of equity-linked private securities offerings by Korean firms from 1989 to 2000, we examine whether such offerings can be used as a mechanism for wealth transfer between issuers and acquirers. For deals involving issuers and acquirers in the same business group (chaebol), the announcement returns for chaebol-affiliated issuers with good past performance are lower than those for other types of issuers if the price discount is larger. In contrast, this deal leads to more value creation for chaebol-affiliated acquirers than other types of acquirers. Furthermore, well-performing chaebol-affiliated acquirers experience a larger wealth loss than other types of acquirers if they buy securities from poorly performing issuers in the same chaebol. We also find that chaebol firms with good past performance tend to sell private securities at a low price to their member firms. This evidence is consistent with tunneling within business groups.

Prognostic factors of breast phyllodes tumors

Background. Phyllodes tumor (PT) is a relatively rare breast tumor, accounting for <1% of all breast tumors. Main body. Adjuvant therapy with chemotherapy or radiation therapy, other than surgical excision, has not been established yet. PT, similar to other breast tumors, is classified as benign, borderline, and malignant according to the World Health Organization classification system, depending on stromal cellularity, stromal atypia, mitotic activity, stromal overgrowth, and tumor border. However, this histological grading system cannot effectively or fully reflect the clinical prognosis of PT. Several studies have investigated prognostic factors for PT as some PTs recur or metastasize to distant sites, and thus, prediction of prognosis is clinically imperative. Conclusion. This review discusses clinicopathological factors, immunohistochemical markers, and molecular factors that have been investigated in previous studies to have an impact on the clinical prognosis of PT
