Thank you, Ken.
This quarter we earned $0.88 per diluted share included in this quarter's results were $0.29 of net investment losses.
Excluding these losses, we earned $1 17 per diluted share. Revenue in our Title segment was $2 billion, up 8% compared with the same quarter of 2021. Commercial revenue was $242 million, up 48% increase over last year. We experienced strength across the board in terms of geography, asset class and deal size. We closed 77 transactions in the U.S. with premium greater than $250,000, up from 34 transactions last year.
Our escrow balances totaled 15 billion at the end of the quarter, up from 10 billion at year end, which indicates a healthy pipeline for commercial activity. Purchase revenue was up 10% during the quarter driven by a 16% increase in the average revenue per order, partially offset by a 5% decline in the number of orders closed.
Our purchase orders declined from an unusually strong quarter in Q1 of 2021, which experienced the release of pent-up demand due to the pandemic. Refinance revenue declined 59% relative to last year, due to the increase in mortgage rates. In the agency business, revenue was $948 million, up 12% from last year.
Given the reporting lag and agent revenues of approximately one quarter, we experienced growth and remittances related to Q4 economic activity.
Our information and other revenues were $302 million, up 9% relative to last year. Revenue growth was primarily due to the recently completed acquisition of ServiceMac. Investment income within the Title Insurance and Services segment was $53 million, a 23% increase relative to the prior year. The increase was primarily due to higher average invested balances.
As the federal reserve raises rates, we expect to generate additional investment income from our escrow deposits, cash balances, 1031 exchange deposits and our bank investment portfolio, where we have over 1 billion of floating rate securities.
On the last earnings call, we estimated based on current deposit balances that a 25 basis point increase in the federal funds rate would equate to a $15 million to $20 million increase to our annualized investment income in the Title segment. We believe this estimate is still appropriate and expect to see the benefit of the Fed's March rate hike beginning in the second quarter. Based on the forward curve for the fed funds rate, we expect our investment income to grow by about $150 million on an annualized basis by the end of this year. Pre-tax margin in Title segment was 11%.
Turning to the Specialty Insurance segment, operating revenue in our home warranty business totaled $104 million, up 5% compared with last year. Pre-tax income in home warranty was $16 million, up from $13 million in the prior year, primarily due to lower claims activity as the loss rate fell from 54% to 46%.
Our property and casualty business had a pretax loss of $4 million this quarter. To date, our policies-in-force have declined by 88% since the beginning of 2021. And we expect the full wind down of the property and casualty business to be completed in the third quarter of this year. The effective tax rate for the quarter was 24.6%.
As a result of recent acquisitions, we expect that our normalized effective tax rate will be 24.5% slightly higher than the 24% rate we've been using as a benchmark for the last several years since the larger portion of our pretax income is now coming from our non-insurance businesses and is subject to higher state income taxes. In the first quarter, we repurchased 1.6 million shares for a total of 108 million at an average price of $69.04.
So far in the second quarter, we've repurchased an additional 1.7 million shares for a total of 100.2 million at an average price of $60.54.
As Ken mentioned in May, we expect to close our acquisition of Mother Lode Holding Company. The purchase price is $300 million, which represents 5.1 times trailing 12-month adjusted EBITDA.
Our debt-to-capital ratio as of March 31 was 29.1% or 23.4% excluding secured financings payable.
Now I would like to turn the call back over to the operator to take our questions.
