What is a companies incentive to issue rights in a bear market?

From what I gather a rights issue is when a company will offer its existing shareholders additional shares in a company.

So apparently a bull market is when the stock prices are going up (like an exponential graph) and a bear market is the opposite when you see share prices fall. Is this right?

So why would a company issue rights if its stock price is going down? Is this sort of like trying to get enough capital to go through a tough period?
