Aflac Inc. AFL is scheduled to report second-quarter 2017 financial results on Jul 27, after the closing bell.Last quarter, Aflac surpassed the Zacks Consensus Estimate by 3.09%. The company exceeded earnings estimates in three of the last four quarters with an average positive surprise of 0.85%.Let’s see how things are shaping up for this announcement.Q2 Flashback Aflac has huge exposure to the life insurance business in Japan and has thus been suffering from a persistent low interest rate in the region. The same is expected to have impacted earnings in the to-be-reported quarter.Nevertheless, sales from this segment will benefit from an increase in third-sector sales given the company’s emphasis on promoting these products which are less interest rate sensitive and carry strong and stable margins. Also, the introduction of third-sector products such as a cancer insurance product early last year, revised EVER and get products in the first quarter have been well received in the market place and will contribute to top-line growth. On the other hand, the company’s efforts in pulling out first-sector products and repricing other products in this category to fight the prolonged low interest rate environment may continue to restrict their sales.. In its U.S. business segment, we expect to see improved persistency, which in turn should support premium growth. The segment’s expense ratio is expected to remain high due to investments in a certain platform, including group administrative platform, enrollment platform and related technology.However, the company’s continuous efforts to return capital to its shareholders via share buyback will cushion its bottom line.The company will, however, incur high cost on account of its Japan branch conversion.Aflac Incorporated Price and EPS Surprise Aflac Incorporated Price and EPS Surprise | Aflac Incorporated QuoteEarnings WhispersOur proven model does not conclusively show that Aflac is likely to beat on earnings this quarter.
