FORM 8-K
Regulatory Filings 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 content describes a settlement agreement related to a private securities class action litigation, including details about settlement payments and issuance of shares. There are no financial statements or comprehensive financial data presented, nor is this an annual or quarterly report. The document is not a transcript, proxy, or governance report. It is a regulatory announcement of a significant legal settlement event. Therefore, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous SEC filings that do not fit other specific categories.

FORM 8-K
Capital/Financing Update Classification · 100% 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 content includes details about a loan amendment agreement and an at-the-market sales agreement, both related to financing activities. There are no financial statements or comprehensive financial performance data presented, only descriptions of financing agreements and related terms. This fits the category of Capital/Financing Update (CAP), which covers updates on company fundraising and capital structure changes. The document length and detail support this classification, and it is not an announcement of a report or a certification, so it is not RPA or RNS.

Capital/Financing Update Classification · 100% confidence The document is a prospectus supplement filed pursuant to Rule 424(b)(5) related to an at-the-market equity offering of common stock. It includes detailed information about the offering, use of proceeds, risk factors, and incorporation by reference of prior SEC filings such as the Annual Report on Form 10-K and Quarterly Reports on Form 10-Q. The document is a registration and offering document for capital raising purposes, not a financial report or earnings release. Therefore, it fits the category of Capital/Financing Update (CAP).

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 mentions Item 2.02, which is "Results of Operations and Financial Condition," and states that the company announced its financial results for the second quarter ended September 30, 2013. It also references a press release attached as Exhibit 99.1. The document is 3162 characters long, which is relatively short and mainly serves as an announcement of the earnings release rather than containing detailed financial statements or analysis itself. According to the rules, initial announcements of quarterly financial results (key highlights only) correspond to the Earnings Release (ER) category. Therefore, this document should be classified as an Earnings Release (ER).
