8-K
Capital/Financing Update Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events that shareholders should know about. The text describes an underwriting agreement and the exercise of an option to purchase additional shares, indicating a financing event. The document length is 3800 characters, which is relatively short and focused on a specific capital raising event. There are no financial statements or comprehensive financial data included, only a description of the offering and related legal opinions. Therefore, this filing is best classified as a Capital/Financing Update (CAP) rather than a full financial report or other category.

Earnings Release Classification · 95% confidence The document is a Form 8-K/A, an amendment to a previously filed Form 8-K. It specifically amends the financial results announcement for the fourth quarter and full fiscal year ended March 31, 2017. The document includes a press release as an exhibit but does not contain the full financial statements or detailed financial analysis itself. The text states that the information is not "filed" for certain regulatory purposes and is primarily an announcement of financial results rather than the full earnings report. The document length is 4122 characters, which is relatively short and consistent with an announcement rather than a full report. Therefore, this document is best classified as an Earnings Release (ER), which is the initial announcement of quarterly or periodical financial results with key highlights only.
