Citigroup (NYSE:C) became the latest company to slash its quarterly dividend to a token penny per share yesterday. The news follows a similar move by banking rival Bank of America (NYSE:BAC) last week.

In fairness, the bank would send a mixed message to ask for TARP money with one hand while handing out chunky dividend checks with the other. Panhandlers shouldn't have holes in the bottoms of their tin cups.

However, this fascination with penny dividends rubs me the wrong way.

Citigroup and Bank of America aren't the only ones flicking copper at their shareholders. PremierWest Bancorp (NASDAQ:PRWT) and tiny REIT MHI Hospitality (NYSE:MDH) slashed their once-bountiful quarterly payouts to $0.01 a share. Other banks making similar slashes in recent months include Fifth Third Bancorp (NASDAQ:FITB), Seacoast Banking (NASDAQ:SBCF) and the aptly named Cascade Bancorp (NASDAQ:CACB), according to

What's the point? Even with their share prices falling into the single digits, it's not as if the new yields will win over conservative income investors. The sound of payout-slashing desperation should be enough to scare away dividend fans for some time.

So what's going on here? Is this just some bogus facade? Are the few banks who survive hoping that we forget this ever happened in a few years, as they proudly proclaim that they have paid decades of uninterrupted dividends?

Just keep your stupid pennies, okay? If things are that bad, you can probably use the money. Spare yourself the paperwork and postage, too. 

If I want sustainable yields, I can probably do better by reading the latest issue of our Income Investor newsletter, or banking on stocks that are actually hiking their dividends. If your financial statements aren't making sense, you have no business giving out cents.

A penny for your thoughts? Just keep it, please.
