The ProShares Russell 2000 Dividend Growers ETF, a dividend spin on the Russell 2000, the benchmark U.S. small-cap index, tracks the Russell 2000 Dividend Growth Index. That index includes small-cap firms with dividend increase streaks of at least a decade. Index constituents are screened for liquidity and dividend status, then selected and equal weighted subject to a maximum sector weight of 30%.

Bats is one of three exchanges that provide coverage for the $2.4 trillion U.S.-listed ETF market, competing against the dominant NYSE Arca exchange, which lists ETFs worth $2.23 trillion, and Nasdaq Inc.

Earlier this year, Chicago Board Options Exchange revealed it is acquiring Bats for a deal that, when initially announced, was valued at $3.2 billion.

Bats has been enticing ETF listings through its cash incentives programs. Recently, Bats adopted a program that would allow lead market makers to receive as much as $400,000 per ETF each year on the BATS exchange, depending on the average daily volume.
