Amended Disclosures: Update Investment Assumptions Along with the Numbers
Compare amounts, schedules, and counterparties in original and subsequent filings, rather than only scanning amendment tables. Reflect the changes in calculations and investment notes.
An amended disclosure explains what changed in an earlier announcement and why. Use the latest effective information for current decisions while retaining the revision history to see how financing and business timetable assumptions have changed.
Keep the latest filing alongside the original announcement
Even when the company name and disclosure title match, the event or issuance series may differ, so match the original filing date and the document being amended. Read the reason, changed items, and before-and-after values, then check that the same values carry through the main text. DART's final-report search helps locate current information, but earlier documents are needed to see the original commitments and the process of change. A simple typo correction differs in significance from a change in financing size, counterparty, or contract terms, so do not flag them with the same warning.
Trace how far a changed number affects the calculation sheet
When a paid-in share issue price changes, the effect on dilution and funding plans depends on whether proceeds or share count change. A delayed payment date can alter assumptions about short-term cash capacity and debt maturities. A reduction in a supply contract amount calls for a review of revenue recognition timing and earnings contribution. Finding every calculation that uses the changed number matters more than merely replacing that one input. First also check whether the units have changed between won, thousands of won, and millions of won.
Assess explanations through patterns and actual results
An amendment alone does not establish deliberate misconduct or weakness. Revising estimates as terms are finalized differs from a reduction or cancellation caused by contractual nonperformance. Repeated changes to the same paying counterparty or payment timetable do, however, provide grounds to examine execution feasibility separately. After an amendment, confirm completion through actual payment results, receipt of proceeds, share issuance, and contract performance disclosures. Record the time and reason for revisions in investment notes to reduce the risk of later interpreting the information as if it had been known from the start. Some amendments change the premise without changing the figures. If a firm contract becomes a matter under negotiation, or new conditions precedent to payment are added, the likelihood of realizing the stated amount changes. Record wording changes as changes in calculation assumptions too.
Worked example
Hypothetical example: Assume a plan to issue 1 million new shares at KRW 10,000 is amended to an issue price of KRW 8,000 with the quantity unchanged. Planned gross proceeds fall by KRW 2 billion, from KRW 10 billion to KRW 8 billion, while dilution based on share count remains unchanged. Conversely, increasing the quantity to 1.25 million shares to maintain KRW 10 billion preserves proceeds but increases dilution. Identify the changed item in the amendment table, then accurately revise the calculation it affects.
What to check
- Match the original filing date and the event being amended.
- Compare the reason, before-and-after values, and units with the main text.
- Update every calculation assumption that uses the changed number.
- Track amendments to announcements separately from actual transaction completion.
