Thank you, Michael. On Page 4 of the presentation, we highlight the company's key financial metrics for the fourth quarter and total year 2020. Net income before noncontrolling interest for the quarter was $16.2 million, an increase of $11.6 million over the prior year, driven by continued growth in our insurance business and strong performance in our mortgage operations.
The net loss for the year was $25.2 million, driven by unrealized mark-to-market losses on our holdings of Invesque. Excluding investment gains and losses, revenues were up 18% for the quarter and 17% for the total year, driven by improvement in insurance top line results, including contributions from our warranty acquisition and increased volumes and margins in our mortgage business.
Adjusted net income for the quarter was $16.2 million, up 54% from the prior year. For the total year 2020, that same metric was $51.4 million, up 86% compared to 2019. The growth in both periods was driven by the same factors that supported improvement in revenues.
On the bottom of the page, we show a bridge from adjusted net income to total pretax income highlighting the key differences between the 2 metrics. Book value per share as of year-end 2020 was $10.90, which represented a decrease of 5.4% versus the prior year, primarily due to negative marks on equities. Book value per share increased 5.2% in the fourth quarter of 2020, driven by net income and share buybacks during the quarter. Our capital and liquidity position remains strong, with cash and cash equivalents of $136.9 million as of the end of the year including $80 million held outside our statutory insurance companies.
On Page 5, we have updated our KPI trends. For 2020, we have refined our key operating related non-GAAP measure, moving from operating EBITDA to adjusted net income. Both metrics remove realized and unrealized gains and losses, purchase accounting amortization, stock-based compensation and nonrecurring items. Adjusted net income differed from operating EBITDA does not add back corporate interest expense or taxes. We believe that adjusted net income better aligns with similar metrics that are used by our peers, particularly in the insurance industry. Organic growth in adjusted net income was 49% for the quarter and 77% for the total year. These strong operating results were driven by the outperformance of our mortgage business and continued stable positive earnings performance in our insurance operations.
We continue to see strong momentum in our insurance company top line results as evidenced by gross written premium and premium equivalents. For 2020, premiums and equivalents increased 29%, led by the acquisition of Smart AutoCare and expansion in commercial and other specialty programs. As a reminder, much of the increase in this metric ends up on the balance sheet, as GAAP recognizes the revenue over the life of the contracts. Deferred revenues and unearned premiums, which represent this future earnings potential, stood at $1.26 billion, up 48% year-over-year, driven by 20% organic growth and the acquisition of Smart AutoCare.
Turning to Page 6. We highlight our capital allocated between our insurance business and Tiptree Capital, along with their respective returns to assist investors in understanding Tiptree's intrinsic value. In total, our 2020 adjusted return on average equity improved to 13.1%, an increase from 6.8% in 2019. Our insurance business, Fortegra, improved its adjusted return on average equity to 15.2% from 12.3% in the prior year, driven by growth in the capital-light warranty services contract business and growth in commercial and personal lines programs, all while maintaining a consistent combined ratio in the low 90s.
Our mortgage business generated outsized returns on capital, driven by growth in volumes and margins, both of which were partially offset by increased interest expense resulting from our upsized corporate borrowing facility completed in early 2020.
With that, let's turn to our insurance company results. For 2020, improvement in sales volumes was driven by growth in warranty, commercial and other specialty programs. Gross written premiums and equivalents reached $1.7 billion, up 29% in total or 12%, excluding our acquisition of Smart AutoCare. In the fourth quarter, we saw premium growth accelerate to 36% year-over-year, led by U.S. warranty programs, which increased 71%; U.S. insurance programs, which grew 22%; and European warranty programs, which grew 83%.
For the year, underwriting and fee margin increased $30 million or 21%. Our combined ratio improved to 91.5%, demonstrating our ability to continue to grow profitably in our insurance business despite the economic headwinds we experienced in 2020.
Adjusted return on average equity continues to trend positively, reaching an annualized 18.6% in the fourth quarter of 2020. We expect continued growth through our capital light, vertically integrated warranty offerings and commercial and other specialty programs, the latter of which is benefiting from hardening markets.
In October, as part of our overall plan to increase financing capacity to support that growth, we finance -- we refinanced our asset based premium finance facility, extending the maturity for 3 years and upsizing the amount to $75 million. This complements the refinancing of Fortegra's revolving credit facility completed in the second quarter.
Turning to the insurance investment portfolio on Page 9. Our total investments and cash and equivalents grew by $147 million year-over-year, up 26%. $589 million of our investments or 83% is held in liquid, highly rated fixed income securities or cash. The average rating on that portion of the portfolio is AA, which we believe provides excellent strength to our capital base. For the year, net investment income was $9.9 million, up $1.2 million driven by the growth in the portfolio despite the low interest rate environment. For the year, net realized and unrealized losses were $11.9 million, driven by unrealized losses on our Invesque Holdings.
On Page 11, we present the results of Tiptree Capital, which today consists of our Invesque shares, shipping and mortgage operations. For the year, the pretax loss was driven by unrealized losses on our investment in Invesque mentioned earlier. 2020, adjusted net income in Tiptree Capital increased to $33.1 million, primarily driven by improvements in mortgage volumes and margin, and a full year of operations from the vessels purchased in 2019 in our maritime shipping business.
As Michael mentioned, our mortgage business has benefited from several tailwinds including higher refinance volumes supported by both low rates and rising home prices. Margins were 150 to 200 basis points higher than normal driven by COVID related capacity constraints. And lastly, we've been able to retain mortgage servicing rights at relatively low valuations providing opportunity for value appreciation and future rising interest rate environment.
Now we will turn the call back to Michael to conclude our prepared remarks.
