What it is
A shareholder pledges shares to a lender in exchange for a loan. When a largest or 5%+ shareholder of a Korean listed company signs, extends or changes such an agreement, the details and the number of pledged shares appear in the ownership report.
Margin call risk
If the pledged shares fall below the required collateral ratio, the lender can demand more collateral or sell the shares. Sales of a major holder's stake can weigh on the share price and affect control of the company.
What to keep in mind
Check what portion of the holding is pledged, the loan period and the collateral maintenance ratio, and whether the filing reports a new loan or simply an extension.
