A DEF 14A covers the proxy statement, with executive pay and the shareholder votes, so if you follow NKX and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full NKX filings page.
Our archive holds no DEF 14A proxy statements from Nuveen California AMT-Free Quality Municipal Income Fund over the last 12 months. You will find everything else we hold for the company on the full NKX filings page.
