FORM 8-K
Regulatory Filings Classification · 100% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce unscheduled material events or corporate changes. The content describes a legal event regarding a court dismissal of a civil action and the company's intention to appeal. It does not contain financial statements or detailed financial data. The document is not an annual or quarterly report, earnings release, or any other detailed financial filing. It is a regulatory announcement of a legal proceeding event. Therefore, the most appropriate classification is Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory announcements that do not fit other specific categories.

FORM 8-K
Earnings Release Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events. The text specifically states that the company announced its financial results for the fourth quarter and full fiscal year ended March 31, 2015, and that the full text of the press release is attached as Exhibit 99.1. The document itself is only 3123 characters, which is relatively short and mainly serves to announce the earnings release rather than containing detailed financial statements or analysis. According to the rules, an initial announcement of quarterly or periodical financial results with key highlights only is classified as an Earnings Release (ER). Therefore, this document is best classified as an Earnings Release (ER).
