The increases in direct written premiums and net written premiums are a result of new business production, and rate increases. For the six months ended June 30, 2024, the Company achieved exposure count growth across all lines of business, including 11.9%, 4.9% and 10.3% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2023. Additionally, for the six months ended June 30, 2024, average written premium per exposure increased 12.4%, 8.5% and 8.8% in Private Passenger Automobile, Commercial Automobile and Homeowners lines, respectively, compared to the same period in 2023.

For the six months ended June 30, 2024, losses and loss adjustment expenses incurred increased by $30.4 million, or 9.8%, to $341.1 million from $310.7 million for the comparable 2023 period. The increase in losses is driven by our larger policy counts and current market conditions, specifically inflationary impacts on our Private Passenger Automobile book of business, offset by a transaction related to the Massachusetts Property Insurance Underwriting Association (“FAIR Plan”).
Since 1998, the Company has been a member company of the FAIR Plan. The FAIR Plan is a residual market insurance association in which all companies writing basic property insurance in the Commonwealth of Massachusetts are required to participate with profits and losses shared among member companies on a written premium basis. On April 1, 2024, the Massachusetts Division of Insurance approved a restructuring of the FAIR Plan transforming it from a partnership that shares profits and losses with member companies to a stand-alone, risk bearing entity, and distributing the accumulated members’ equity.
The Company carried a net asset of $13.3 million as of June 30, 2024, representing its estimated share of members’ equity based on the estimated profitability of the FAIR Plan. As an element of the restructuring, the FAIR Plan calculated each member company’s equity balance and notified the Company that our net asset balance was $23.0 million as of June 30, 2024. As a result, the Company recognized an increase in our asset and an underwriting gain of $9.7 million through the release of prior year loss reserves (“FAIR Plan Development”). Additionally, the restructuring required the Company to establish assets as of June 30, 2024, including an investment in FAIR Plan Trust of $14.9 million and a receivable of $8.0 million, of which $6.4 million was paid on July 2, 2024. The remaining receivable is expected to be paid by November 1, 2024. Going forward, the Company’s Investment in FAIR Plan Trust will be adjusted to its current fair value on a quarterly basis with changes recognized through earnings.
Loss, expense, and combined ratios calculated for the quarter ended June 30, 2024, were 70.0%, 29.9%, and 99.9%, respectively, compared to 71.0%, 30.9%, and 101.9%, respectively, for the comparable 2023 period. The decrease in the expense ratio is primarily driven by the increase in earned premiums and a decrease in contingent commission expenses. Loss, expense, and combined ratios calculated for the six months ended June 30, 2024 were 70.6%, 30.3%, and 100.9%, respectively, compared to 78.9%, 31.1%, and 110.0%, respectively, for the comparable 2023 period. The prior year loss ratio was impacted by a severe weather event, totaling $32.1 million of losses.
Total prior year favorable development included in the pre-tax results for the quarter ended June 30, 2024 was $19.4 million compared to $10.0 million for the comparable 2023 period. Total prior year favorable development included pre-tax results for the six months ended June 30, 2024 was $30.4 million compared to $21.5 million for the comparable 2023 period. The increase in 2024 is related to the FAIR Plan Development noted above.
