Not every company is slashing its dividend these days. Some of the market's better performers are easing up on their purse strings, sending more money out to their shareholders.

Readers of the Motley Fool Income Investor newsletter can certainly appreciate that kind of thinking. Let's take a closer look at some of the companies that inched their payouts higher this past week.

We'll start with Coca-Cola (NYSE:KO). The world's largest beverage company is carbonating its quarterly dividend, lifting it 7% to $0.44 a share. Coca-Cola paid out a sweet $3.8 billion in shareholder disbursements last year.

Abbott Labs (NYSE:ABT) also shows healthy generosity. The drug and medical device maker will jack up its quarterly payout by 10% to $0.44 a share. Shareholders must be used to this by now. Abbott Labs has increased its distributions in each of the past 38 years.

Abbott's move bumps its yield to 3.2%. That pales when compared to 6% at GlaxoSmithKline (NYSE:GSK) and 7.8% at AstraZeneca (NYSE:AZN), but it's hard to scoff at the high likelihood of Abbott's rate climbing year after year in the future.

Genuine Parts (NYSE:GPC) is also motoring along. The maker of auto parts is coming through with a 3% uptick in its quarterly dividend, to $0.41 a share. The automotive sector may be cyclical, but Genuine Parts has found a way to prop up its payments during the past 54 years.

Finally, Rogers Communications (NYSE:RCI) does more than just phone it in. The Canadian communications and media giant will expand its quarterly distributions by 10% to $0.32 a share.

Some of these moves may not seem like much, but there are plenty of companies that haven't been able to support even their current dividends lately. Home Properties (NYSE:HME) became the latest company to slash its quarterly payout, with the apartment REIT reducing its rate by 13% on Thursday.

Subscribers to the Income Investor newsletter can appreciate the companies sending more and more money to their investors. The newsletter singles out companies that are committed to growing their distributions, with market-thumping results.
