Thank you, Jay. First, the point to note is our typical contract period is from June 1 to May 31 of the following year. With respect to net premiums earned, third quarter net premiums declined slightly $247,000 from $279,000 last year due to lower capital deployed in the period compared to last year.
Net premiums earned for the 9 months ended September 30, 2020, increased $646,000 from $372,000 in the prior year. The increase is due to only 1 month of premium being recognized through the first 9 months of last year as a result of previous accelerated premium recognition when compared to normal premium recognition in 2020.
For the third quarter of 2020, we experienced a small loss on net realized investments and a small negative change in fair value of equity securities compared to gains in last year's third quarter. Net investment and other income for the first 9 months of 2020 totaled $90,000 compared to $182,000 last year.
Net realized gains of $325,000 were significantly higher than $3,000 last year. However, we experienced a $343,000 decline in fair value for equity securities compared to a gain of $20,000 last year.
Total expenses, including loss and loss adjustment expenses, policy acquisition costs and underwriting expenses, and general administrative expenses reduced further in the third quarter and for 9 months of 2020 compared to last year. The reductions in total expenses are due primarily to continued reductions on efficiencies in our G&A cost, which declined to $767,000 through the first 9 months of the year from $808,000 last year.
With the higher revenues and reduced expenses, we generated a reduced net loss for the 9 months ended September 30, 2020, of $232,000 or $0.04 per share compared to a net loss of $366,000 or $0.06 per share through the first 9 months of last year. The third quarter 2020 loss increased slightly to $33,000 from $15,000 in last year's third quarter.
With respect to financial issues, we use various measures to analyze the growth and profitability of our business operations. For our reinsurance business, we measure underwriting profitability by examining the loss ratio, [ with set ] expense ratio, underwriting expense ratio and combined ratio.
Our loss ratio, which measures underwriting profitability, is the ratio of losses and loss adjustment expenses incurred to net premiums earned. Our loss ratio for the third quarter and first 9 months of 2020 was 0%, the same as last year, but there was no loss or loss adjustment expenses in either period.
Our acquisition cost ratio, which measures operational efficiency, compared to policy acquisition cost and other underwriting expenses to net premium earned. Our acquisition cost ratio was 10.9% and 11% for the third quarter and first 9 months of 2020, respectively, compared to 11.1% and 11% for the same periods last year. The decrease in the third quarter was due to lower weighted average acquisition costs on reinsurance contracts in force in the period compared to last year's third quarter. The acquisition cost ratio remained unchanged for the 9-month period ended September 30, 2020 and 2019.
Our expense ratio, which measures operating performance compared to policy acquisition costs and general administrative expense with net premiums earned. The expense ratio for the third quarter and first 9 months of 2020 were 107.7% and 129.7%, respectively, compared to 105.7% and 228.2% for the same periods last year. The increase in third quarter is due primarily to a lower denominator in net premiums earned as recorded during the third quarter when compared with the previous period. The decrease for the 9 months ended September 30, 2020, was due to reduced general and admin expenses this year and a higher denominator in net premiums earned to date in 2020 when compared with the same period in 2019.
Our combined ratio, which is used to measure underwriting performance, is the sum of the loss ratio and the expense ratio. The combined ratio for the 3 and 9 months ended September 30, 2020, was 107.7% and 129.7%, respectively, compared to 105.7% and 228.2% for the same periods in 2019. The increase in the third quarter was due to the lower denominator in net premiums earned compared to last year, and the decrease through the first 9 months of the year resulted from our higher denominated net premiums earned and the reduced total expenses in 2020 when compared with the prior year.
Now turning to the balance sheet. Total investments, which comprises of investments in equity securities, totaled $635,000 at September 30, 2020, compared with $692,000 at December 31, 2019. The decrease is due to the sale of equity securities during the current year.
At September 30, 2020, cash and cash equivalents and restricted cash and cash equivalents totaled $7.4 million compared with $8 million at December 31, 2019.
Total shareholder equity at September 30, 2020, was $7.8 million compared to $8 million at December 31, 2019. At September 30, 2020, our book value per share was $1.37.
Now with that, I'd like to turn the call back over to Jay. Jay?
