Quarterly business ascended to an all-time high at National Mortgage Insurance Corp. As the book of business grew, so did delinquency.

NMI earned $17 million before taxes from Oct. 1, 2017, through the end of last year, according to its fourth-quarter earnings report.

Earnings at the Emeryville, California-based firm soared from just $7 million in the fourth-quarter 2016 but slipped from $19 million in the third-quarter 2017.
