BlackRock (NYSE: BLK), the world’s largest asset manager and parent company of iShares, the world’s largest issuer of exchange traded funds, said today that as of Jan. 2, 2015, two of its ETFs will start participating in the NYSE Arca ETP incentive program.

The iShares Interest Rate Hedged High Yield Bond ETF (NYSEArca: HYGH) and the iShares Asia/Pacific Dividend ETF (NYSEArca: DVYA) are the two iShares ETFs that will participate in the program, which is “designed to incentivize Market Makers to undertake Lead Market Maker (“LMM”) assignment in exchange-traded products (“ETPs”) listed on NYSE Arca,” according to a statement issued by BlackRock.

“While the impact of participation in the NYSE Arca ETP Incentive Program, which is optional, cannot be fully understood until objective observations can be made in the context of the NYSE Arca ETP Incentive Program, potential impacts on the market quality of HYGH and DVYA may result, including with respect to the average spread and average quoted size for HYGH and DVYA,” according to the statement.

HYGH, which debuted in May and now has almost $47 million in assets under management, tries to reflect the performance of the Citi High Yield (Treasury Rate-Hedged) Index, which tracks a basket of high-yield bonds with a built-in hedge against rising interest rates. The fund tracks bond securities issued from the U.S. or Canada with at least one year remaining to maturity.

The ETF has an effective duration of 0.36 years and a 30-day SEC yield of 5.67%.
