Selected Financial Information

($ in millions, except per share data)

Total revenue for the third quarter of 2017 was $1.5 billion, an increase of 1 percent relative to the third quarter of 2016. Net income in the current quarter was $21.4 million, or 19 cents per diluted share, compared with net income of $107.3 million, or 96 cents per diluted share, in the third quarter of 2016. The current quarter results include an expense of $152.4 million, or 89 cents per diluted share, for the completion of the company’s pension plan termination. Net realized investment losses in the current quarter were $7.0 million, or 4 cents per diluted share, compared with net realized gains of $9.5 million, or 6 cents per diluted share, in the third quarter of last year. In addition, this quarter’s effective tax rate of negative 17.9 percent includes a benefit of $8.1 million, or 7 cents per diluted share, primarily related to certain settlements with taxing authorities and tax benefits recorded in connection with the termination of the pension plan.

“In the third quarter, our company continued to deliver strong operating results,” said Dennis J. Gilmore, chief executive officer at First American Financial Corporation. “We are seeing sustained growth

in our purchase business, with revenues up 10 percent this quarter, and the positive momentum in our commercial business continued, with revenues up 6 percent from last year. The refinance market, while down sharply from last year, is currently stable and we have adjusted our cost structure to match the lower order volumes. During the quarter, we also saw additional benefit from growth in investment income driven by the increase in short-term interest rates.

“Noteworthy acquisitions this quarter included the purchase of a leading title agency in Nevada and the buyout of our majority joint venture partner in a title information company.

“The recent hurricanes and wildfires resulted in extreme hardships for many people, including a number of First American’s employees and customers. While our immediate focus was on helping our impacted employees and providing them with the resources they needed, I’m proud of how hard our people worked to get our operations back up and running, allowing us to quickly resume service to our customers. We ultimately expect the company’s financial results will not be significantly impacted.

“As we enter the fourth quarter, we are optimistic given the expected seasonal strength in our commercial business and the continued growth of the purchase market.”

Title Insurance and Services

($ in millions, except average revenue per order)

Total revenues for the Title Insurance and Services segment during the third quarter were $1.4 billion, essentially flat compared with the same quarter of 2016. Direct premiums and escrow fees were down 1 percent compared with the third quarter of 2016, driven by a 20 percent decline in the number of direct title orders closed that was largely offset by a 24 percent increase in the average revenue per direct title order. The growth in the average revenue per direct title order to $2,298 was primarily attributable to the shift in the order mix to higher-premium residential purchase and commercial transactions, higher average revenue per order from commercial transactions, and higher residential real estate values. Agent premiums were up 1 percent in the current quarter compared with last year, largely reflecting the normal reporting lag of approximately one quarter.

Information and other revenues were $199.3 million this quarter, an increase of $11.3 million, or 6 percent, compared with the same quarter of last year. This increase was driven by a $23.6 million impact from recent acquisitions, partially offset by lower revenues from the company’s default and mortgage-related information products, which largely resulted from the decline in overall market activity.

Investment income was $37.9 million in the third quarter, up $8.9 million, or 31 percent, primarily due to the increase in short-term interest rates that drove higher interest income in our tax-deferred property exchange business and our floating rate mortgage-backed securities portfolio. In addition, investment income benefited from an increase in average invested balances in our debt securities portfolio. Net realized investment losses totaled $7.2 million in the current quarter, compared with gains of $8.4 million in the third quarter of 2016.

Personnel costs were $421.8 million in the third quarter, an increase of $12.5 million, or 3 percent, compared with the same quarter of 2016. The increase was driven by a $17.4 million impact from recent acquisitions and $9.0 million in out-of-period personnel expenses, partially offset by $13.9 million in lower costs across a number of categories, including temporary labor costs and overtime.

Other operating expenses were $196.5 million in the third quarter, down $1.7 million, or 1 percent, compared with the third quarter of 2016. An increase of $10.5 million from recent acquisitions was more than offset by $12.2 million in expense reductions, primarily due to lower production-related expense from the decline in order volume and lower software, legal and bad debt expense compared with last year.

The provision for policy losses and other claims was $46.7 million in the third quarter, or 4.0 percent of title premiums and escrow fees, compared with a 5.5 percent loss provision rate in the third quarter of 2016. The current quarter rate reflects an ultimate loss rate of 4.0 percent for the current policy year and no change in the loss reserve estimates for prior policy years.

Depreciation and amortization expense was $34.4 million in the third quarter, an increase of $11.4 million, or 49 percent, compared with the same period last year. The increase was primarily attributable to a $4.7 million title plant write-off and higher amortization expense associated with internally developed technology and purchased software licenses.

Pretax income for the Title Insurance and Services segment was $181.2 million in the third quarter, compared with $188.7 million in the third quarter of 2016. Pretax margin was 13.0 percent in the current quarter, including a 40 basis point margin impact from net realized investment losses, compared with 13.5 percent last year, which included a 50 basis point margin impact for net realized gains.

Total revenues for the Specialty Insurance segment were $118.5 million in the third quarter of 2017, an increase of 8 percent compared with the third quarter of 2016. The increase in revenues was driven by higher premiums earned in the home warranty business line. The loss ratio in the home warranty business declined significantly this quarter compared with last year due to lower claim frequency and severity. The decrease in claim severity was primarily due to operational improvements in our claims management processes. In addition, both claim severity and frequency benefited, to some extent, from favorable weather conditions as compared with last year. Our property and casualty business experienced high claim losses in the quarter due to higher claim severity and frequency. However, the overall loss ratio for the segment still declined to 65.2 percent compared with 69.0 percent last year. As a result, the segment’s pretax margin in the current quarter was 5.2 percent, compared with 1.6 percent in the third quarter of last year.
