First Hawaiian Bank said Monday it has restructured its balance sheet related to its investment securities portfolio and expects the move to improve its overall financial position.

The company said it sold about $898 million of its lower-yielding securities, resulting in an after-tax loss of about $17.6 million, or 13 cents a share, to be recognized in the fourth quarter of 2018, and $2.1 million to be recognized this quarter. Proceeds from the sales were reinvested in debt securities issued by U.S. government agencies.

First Hawaiian estimates the restructuring will result in about $6.1 million in after-tax earnings accretion this year.
