Thank you, Ernie. Good morning. Let me begin by providing some additional detail on the driver of the net loss of $49.5 million reported for the quarter. The primary driver was a $60.5 million noncash goodwill impairment that was mostly nontax deductible and negatively impacted earnings per share by $2.20. Adjusted net income, which excludes the impact of goodwill was $11.3 million or $0.41 per share.
Management firmly believes our stock is undervalued and that the last several years of weather-related catastrophes has had an adverse impact on our stock price. With our stock trading below tangible book value at the time of the annual goodwill impairment analysis and the overall market disruption and estimated valuation multiples in the property insurance market, we determined that an impairment of a portion of our goodwill was appropriate. Importantly, we believe the fundamental performance of the business in the fourth quarter and the earnings potential for Heritage in 2022 and beyond is better reflected by our fourth quarter adjusted net income and combined ratio.
Adjusted net income of $11.3 million for the fourth quarter of 2021 was up $8.5 million from the $2.8 million in the prior year quarter. The year-over-year change primarily stems from current accident year weather and attritional losses and lower general and administrative expenses partially offset by lower favorable prior year reserve development. We instituted a number of underwriting initiatives during 2021. Those efforts allowed us to achieve a net combined ratio under 100 in the fourth quarter of 2021, but more importantly, we expect our efforts to continue benefiting underwriting results in '22 and beyond.
With the current market disruption in both the Southeast and Northeast regions, we will be even more selective in our underwriting as we continue our focus on a diversified, profitable and balanced portfolio. These actions include remaining focused on margin expansion, which includes rate increases, curtailing production in unprofitable areas and tightening our underwriting standards. In addition to making positive rate and underwriting changes, we are also making form changes, which are aimed at lowering loss costs. We expect the majority of our growth will occur from rate increases instead of growth in policies in force and management will continue to stay focused on maintaining and improving our portfolio.
In 2021, our total insured value increased 4.3% over the prior year, which reflected a 10.9% decrease in our Florida personal lines portfolio and a 10.7% increase in our personal lines outside of Florida. Over the same period, our in-force premium increased by 10.1% over the prior year. This demonstrates a positive shift in our portfolio and progress in our profit initiatives. Gross premiums written declined 1.2% overall year-over-year and declined 17.8% in Florida, reflecting our intentional exposure management and re-underwriting efforts. In our 15 other states, gross premiums grew by 16.7% in the fourth quarter of 2021 compared to the prior year. The average rate increase over the prior year period is over 10%.
Net premiums earned increased by 5.6% year-over-year, reflecting an increase in gross premiums earned of $28.2 million that outpaced a $19.8 million increase in ceded premium. Losses for the quarter were down $7.6 million year-over-year due to lower weather losses and an improvement in attritional losses, which were partially offset by lower favorable development. Losses this year were also impacted by both social and economic inflation, which we will continue to evaluate and incorporate into our rates and our inflation guard factors.
The net combined ratio of 93.2% is down 15.5 points compared to 108.7% for the fourth quarter of 2020. Even with a higher ceded premium ratio, our net loss ratio improved by 8.5 points and our expense ratio improved by 7 points. While fewer weather losses contribute to the improvement in the loss ratio, the shift in our book of business geographically, the rate increases and the underwriting changes for new and existing businesses contribute to the lower net loss ratio.
Our net expense ratio also improved to 31.3% in the fourth quarter and 34.7% for the full year of 2021, which represented a 3.8-point improvement from the full year 2020. Shareholder equity decreased by $62 million for the quarter or $2.38 per share, of which $2.26 was related to the goodwill impairment. Management took the opportunity to purchase 1.1 million shares during the fourth quarter at an average price of $6.42. For the full year, we purchased 1.3 million shares for an average price of $6.52 per share. Also, at the end of the fourth quarter, the Board approved a new $25 million repurchase authorization for 2022. At year-end, the company had $26 million of cash at the holding company. In addition, we continue our commitment to returning value to shareholders.
We believe the favorable improvements in the net combined ratio indicate that the fundamentals of the company are trending favorably. As such, we expect to continue to see positive results from these profit initiatives.
