Bulgarian public companies are obliged to disclose almost all aspects of their activities and management. It is of vital importance for the investors to receive the information, disclosed by public companies in the certain time limits, set by the legal framework. Often this is interpreted as an indication of a flaw in management or attempt to hide poor financial results. Publishing delayed regulated information can affect both the stock price increasing its volatility and overall rating. A best practice for the company is to maintain a corporate calendar with specified dates for information disclosure.
