The MRPS are considered debt of the issuer; and the liquidation preference approximates fair value. MARKET AND NET ASSET VALUE INFORMATION Our common shares are listed on the Nasdaq Global Select Market (“Nasdaq”) under the symbol “CHY.” Our common shares commenced trading on the New York Stock Exchange (“NYSE”) in May 2003. On July 2, 2012, the common shares ceased trading on the NYSE and commenced trading on Nasdaq. Our common shares have traded both at a premium and a discount to NAV. We cannot predict whether our shares will trade in the future at a premium or discount to NAV. The provisions of the 1940 Act generally require that the public offering price of common shares (less any underwriting commissions and discounts) must equal or exceed the NAV per share of a company’s common stock (calculated within 48 hours of pricing). Our issuance of common shares may have an adverse effect on prices in the secondary market for our common shares by increasing the number of common shares available, which may put downward pressure on the market price for our common shares. Shares of common stock of closed-end investment companies frequently trade at a discount from NAV. See “Risk Factors - Additional Risks to Common Shareholders - Market Discount Risk.” 24 The following table sets forth for each of the periods indicated the high and low closing market prices for our common shares on Nasdaq, the NAV per share and the premium or discount to NAV per share at which our common shares were trading. NAV is shown for the last business day of each quarter. See “Net Asset Value” for information as to the determination of our NAV.
