Whether it's through stocks, bonds, ETFs, or other types of securities, all investors love seeing their portfolios score big returns. However, when you're an income investor, your primary focus is generating consistent cash flow from each of your liquid investments.Cash flow can come from bond interest, interest from other types of investments, and of course, dividends. A dividend is that coveted distribution of a company's earnings paid out to shareholders, and investors often view it by its dividend yield, a metric that measures the dividend as a percent of the current stock price. Many academic studies show that dividends make up large portions of long-term returns, and in many cases, dividend contributions surpass one-third of total returns.Farmers & Merchants Bancorp Inc. In FocusHeadquartered in Archbold, Farmers & Merchants Bancorp Inc. (FMAO) is a Finance stock that has seen a price change of -18.43% so far this year. The company is currently shelling out a dividend of $0.41 per share, with a dividend yield of 3.14%. This compares to the Banks - Northeast industry's yield of 2.57% and the S&P 500's yield of 1.85%.Taking a look at the company's dividend growth, its current annualized dividend of $0.84 is up 18.3% from last year. Over the last 5 years, Farmers & Merchants Bancorp Inc. has increased its dividend 5 times on a year-over-year basis for an average annual increase of 8.65%. Any future dividend growth will depend on both earnings growth and the company's payout ratio; a payout ratio is the proportion of a firm's annual earnings per share that it pays out as a dividend. Farmers & Merchants Bancorp Inc.'s current payout ratio is 30%, meaning it paid out 30% of its trailing 12-month EPS as dividend.Looking at this fiscal year, FMAO expects solid earnings growth. The Zacks Consensus Estimate for 2022 is $2.66 per share, which represents a year-over-year growth rate of 16.67%.Bottom LineFrom greatly improving stock investing profits and reducing overall portfolio risk to providing tax advantages, investors like dividends for a variety of different reasons. But, not every company offers a quarterly payout.Big, established firms that have more secure profits are often seen as the best dividend options, but it's fairly uncommon to see high-growth businesses or tech start-ups offer their stockholders a dividend. Income investors have to be mindful of the fact that high-yielding stocks tend to struggle during periods of rising interest rates. That said, they can take comfort from the fact that FMAO is not only an attractive dividend play, but is also a compelling investment opportunity with a Zacks Rank of #1 (Strong Buy).
