Leah Stearns
Chief Financial Officer at Copart
Thanks, Jeff. I'll begin with our fourth quarter and fiscal year '24 sales trends. During the quarter, our global unit sales and inventory increased 8% and about 7%, respectively, from the year ago period. For fiscal year '24, Global unit sales increased nearly 10%. This growth was a function of an increase in total loss frequency and share gains.
Focusing on our U.S. business, unit growth was over 6%, which reflected fee unit growth of over 6% and purchase unit growth of over 13%. For fiscal year '24, unit growth was nearly 8% with fee units growing over 7% and purchase unit growth of almost 14%. Consignment or fee units continue to constitute the vast majority of our U.S. unit volumes. Our U.S. unit volume increased -- our U.S. insurance unit volume increased 6% year-over-year and about 7% for fiscal year '24. As Jeff mentioned, our noninsurance unit volume growth has continued to outpace that of our insurance business. This volume growth substantially came from fleet rental and finance units which increased over 20% in Q4 and nearly 28% for the year and dealer units, which increased nearly 10% for the quarter and over 15% for the fiscal year '24. Inventory levels in the U.S. increased over 6% and nearly 9% when excluding low-value and cat units.
Turning to our international business. We saw unit growth of almost 17% in the quarter and 21% for fiscal year '24 with fee units increasing over 17% in Q4 and 22% for the year. Purchased units increased by nearly 13% for the quarter and almost 16% for the fiscal year. Our international business ended the quarter with inventory levels over 9% ahead of the prior year. Global ASPs declined by approximately 5% for the quarter relative to a year ago period and about 3% for the full year. Our U.S. ASPs continue to show resilience and are significantly outperforming the used vehicle market more broadly. While the Manheim used vehicle price index declined by nearly 9% from the year ago quarter and almost 2% sequentially. Our U.S. insurance ASPs declined less than 4% from a year ago for the quarter and increased over 2% sequentially.
Turning to our financial results. Global revenue in the quarter increased to nearly $1.1 billion, representing growth of over $71 million or about 7%. For the year, global revenue increased to more than $4.2 billion, representing growth of over $367 million or nearly 10%. Global service revenue increased nearly $59 million or over 7% for the fourth quarter and almost $363 million or over 11% for the fiscal year, primarily due to increased volumes. Our U.S. service revenue grew by over 6% for the quarter and 10% for the year, and international service revenue grew by nearly 14% for the fourth quarter and 22% for the year.
Global purchased vehicle sales for the fourth quarter increased over $12 million or 8% and over $4 million or about 1% for the fiscal year. Global purchased vehicle gross profit decreased by about 1% in the fourth quarter and for the fiscal year. In the U.S., the purchased vehicle revenue was up over $10 million or 12%, while purchased vehicle gross profit increased less than $1 million or about 11% in the quarter. And for the fiscal year, purchased vehicle revenue decreased about $9 million or almost 3% and purchased vehicle gross profit increased about $4 million or over 18%.
Internationally, purchased vehicle revenue increased by over $2 million or about 3%, and gross profit decreased by almost $1 million or about 11% in the fourth quarter -- and for the full year, purchased vehicle revenue increased almost $14 million or over 4% and purchased vehicle gross profit decreased about $4 million or over 12%. Global yard operations cost, excluding stock-based compensation and depreciation expense increased about $59 million or about 17% from the prior year period. This growth reflects the increase in unit volume as well as approximately $16 million of nonrecurring expenses, primarily related to operating taxes.
In addition, as Jeff noted, given the active and early start to the storm season in 2024, our cat storm response teams incurred seasonally higher costs preparing and positioning resources for several storms which did not produce significant unit volumes. Given the unpredictable nature of catastrophic events during storm season, we absorbed these costs as part of our normal course of serving our customers and their policyholders.
During the quarter, global gross profit was over $453 million, a decrease of $4 million or about 1% and our gross margin percentage decreased by approximately 340 basis points to 42.4% in the fourth quarter. For the fiscal year, global gross profit was over $1.9 billion, an increase of over $170 million or about 10% and gross margin percentage was 45%, an increase of about 10 basis points. In the U.S., our gross profit margin decreased to 46.5% for the quarter and increased to 49.4% for the year. The key drivers of margin compression during the quarter included the impact of nearly $12 million of out-of-period expenses as well as increased salary and benefits expense associated with our yard operations personnel. Our international gross profit margin increased to 24.2% in the quarter and 25.5% for the year.
Turning to general and administrative expenses, excluding stock-based compensation and depreciation expense, spend in the quarter was about $81 million, reflecting an increase of $26 million over the prior year and about $5 million on a sequential basis. For the year, spend was about $288 million, an increase of about $88 million. As we highlighted last quarter, our year-over-year G&A increase continues to reflect our investments in organic product development, our platform functions, the financial consolidation of Purple Wave into our results as well as an increase in third-party project-related costs associated with system implementations.
Across our organization, and as we are investing in expanding our whole card heavy equipment sales functions, our teams are simultaneously focused on deploying emerging technologies to enhance our business processes and systems in pursuit of scalability and operating leverage over the long term. GAAP operating income for the quarter decreased by 8% to over $359 million. And for the fiscal year, GAAP operating income decreased -- or sorry, GAAP operating income increased by over $85 million or nearly 6%.
Finally, fourth quarter GAAP net income decreased by over 7% to over $322 million or $0.33 per diluted common share. For the fiscal year, GAAP net income increased by over 10% to over $1.4 billion. During the quarter, we benefited from over $14 million of incremental interest income as we have actively invested our cash into treasury securities. And for the quarter, our tax rate was 21.1%. And for the fiscal year, it was 20.5%.
Turning to our capital structure. As of the end of July, we had over $4.6 billion of liquidity, which is compromised of nearly $3.4 billion in cash and investments and held to maturity securities and our capacity under our revolving credit facility of over $1.2 billion. We believe that our conservative capitalization is a distinct competitive advantage in our industry, enabling us to operate our business with a horizon that prioritizes ours and our clients' long-term success.
For the year, we generated free cash flow of $962 million, reflecting our operating cash flow generation of $1.473 billion and capital investments of about $511 million. Our investment focus for 2024 remains steadfast with nearly all of our capital being deployed into assets which drives best-in-class outcomes for our customers, including more than 1,100 acres of land acquired and 370 transportation assets as well as enhanced physical infrastructure.
With a new year upon us, I wanted to reiterate that our multi-decade investment horizon and long-standing approach to capital allocation is unwavering. We continue to prioritize investments that grow and diversify our existing marketplace businesses including differentiated products and service capabilities. This includes our approach to yard infrastructure investments, which are critical to ensuring that we are positioned to serve our customers' needs for the long term. We remain focused and disciplined on deploying capital through M&A and strategic partnerships with valuation and/or strategic fit being a major hurdle that opportunistic transactions typically fail to clear. This consistent approach has positioned us to deliver outstanding business outcomes while generating long-term value creation for our shareholders.
And with that, Jeff and I would be happy to take some questions.
