Thanks, Raul, and hello, everyone. In addition to GAAP, we also evaluate our performance based on fair value pro forma results, which we believe present a more consistent view of the underlying trends of the business. Unless I state otherwise, all of the metrics that I will now share with you will be on a fair value pro forma basis for the purposes of comparison to prior year periods. A full list of definitions and reconciliations can be found in our earnings materials.
As Raul mentioned a moment ago, we experienced steady improvement throughout the third quarter that continues into the current quarter. Aggregate originations in the third quarter were $302.4 million, nearly twice the level of our second quarter originations. We are also tracking our progress in returning to our 2019 level of originations, and our third quarter originations were up to 56% of last year's. In September, our originations improved to 67% of last year's, and in October, this improvement continued as we saw aggregate originations for the month increase to $133.6 million, 69% of last year's.
As the overall economic environment has gradually improved, we have cautiously increased our credit decisioning. We remain thoughtful and deliberate in our execution of such changes. Given the encouraging indications we experienced throughout the third quarter and into October, we believe we are well positioned for further improvements, assuming the economy continues to improve.
Total revenue for the third quarter was $136.8 million, down 11% relative to the prior year period. The decrease was primarily due to lower interest income during the period which was $128.7 million, down 7% year-over-year. This was due to a 3% decrease in average daily principal balance and a decrease in portfolio yield to 32%. Noninterest income, which includes cash gain on sale from our whole loan sale program, was $8 million. This was down over the prior year period, reflecting the lower volume of loans sold as well as lower gain on sale premium of 9.9% versus 10.1% in the prior year period.
For the third quarter, net revenue, which is our total revenue after interest expense and net change in fair value, was $92.4 million, down 17% year-over-year. Net revenue was lower due to higher charge-offs, offset by lower interest expense and $10.7 million net improvement in the fair value of our loan portfolio and asset-backed notes. Interest expense of $13.2 million was down 13% year-over-year. The decline in interest expense was driven by a decrease in our average daily debt balance of 8% year-over-year as we have reduced our leverage as our portfolio is paid down and also the decrease in our cost of debt to 3.9% in Q3 relative to 4.2% in the same period a year ago. Net increase or decrease in fair value or net change in fair value includes our current period principal net charge-offs and mark-to-market of our loans and debt. We provide a summary of the net change in fair value in our third quarter 2020 earnings deck.
As you'll see on Slide 15, the third quarter $31.2 million net decrease in fair value consisted of a $10.7 million mark-to-market net increase on our loans and our debt and current period charge-offs of $41.9 million. The mark-to-market adjustments consisted of a $29.1 million mark-to-market decrease related to our asset-backed notes and a $39.8 million mark-to-market increase in our loans receivable.
Now I'll walk you through the drivers of our fair value mark, starting with our asset-backed notes. As of September 30, the weighted average price of our asset-backed notes was 101.1%, up from 98.7% at June 30, reflecting a significant improvement in the prices of our bonds. The increase in the fair value of our bonds resulted in a $29.1 million decrease net change in fair value in net revenue. The improvement in prices is a positive indication of capital markets conditions and accessibility. The $39.8 million increase in fair value of our loans receivable was driven by an increase in the fair value price for our loans to 101.9% as of September 30 from 99.4% as of June 30.
The increase in fair value was mainly driven by 3 factors: first, due to more customers returning to repayment, our remaining life of loan charge-offs decreased to 10.61% at September 30 from 12.73% at June 30; second, consistent with the weighted average decrease in yield on our bonds, the discount rate on our loans decreased to 7.84% as of September 30 from 8.84% as of June 30; third, fewer-than-expected emergency hardship deferrals resulted in a decrease in average life to 0.78 years as of September 30 from 0.8 years as of June 30. Additional supplemental information regarding our fair value assumptions is provided in the appendix section of our third quarter 2020 earnings deck.
Turning to expenses. We have actively reduced discretionary spend across the company. For the third quarter, our total operating expense was $101.6 million, up 9% sequentially from the second quarter. However, excluding the impact of a net liability of $8.8 million in relationship to a legal settlement, our operating expenses were down 0.2% sequentially. By comparison, our operating expenses increased 20% from the second quarter to the third quarter in 2019. Operating costs associated with our auto and credit card products, which are included in our overall OpEx, were $4.2 million for the third quarter. These investments contributed to our year-over-year OpEx increase.
Lower revenue in the third quarter led to adjusted operating efficiency of 63.3%, which was 540 basis points higher than the comparable quarter last year and 330 basis points higher than the second quarter of 2020. Our customer acquisition cost for the third quarter was $207, down from $413 in the second quarter. While our CAC was still elevated relative to the $128 in the prior year period, it is returning to normal levels as origination volumes normalize. As originations increased in September, CAC further decreased to $180 for the month. We are optimizing our marketing investments for the current environment, but we expect an increase in marketing in the fourth quarter as we return to growth and take advantage of the expected seasonal increase in demand.
Our loss from operations on a GAAP basis was $6 million versus net income of $10 million in the prior year quarter. This equated to GAAP net loss per share of $0.22 versus a net loss per share of $6.39 in the prior year quarter. On a non-GAAP basis, our adjusted EPS was $0.15 based on adjusted net income of $4.2 million versus adjusted EPS of $0.64 and adjusted net income of $15.3 million in the prior year quarter. Adjusted net income is the numerator of our adjusted return on equity, which was 3.7% for Q3 versus 14.6% in the prior year quarter.
Our third quarter adjusted EBITDA, which is our proxy for pretax cash profitability, does not factor in the 212 basis point reduction in our remaining cumulative loss estimate since the noncash impact of fair value accounting is backed out. For the third quarter, our adjusted EBITDA was negative $1.2 million compared to $18.6 million in the prior year quarter.
Turning now to credit. Our performance in the third quarter and October showed notable improvements. We continued to see a significant decline in loans in deferral, and at the end of September, only 1.5% of our portfolio was in emergency hardship deferral status. By the end of October, deferrals had further decreased to 1%. Since the start of the pandemic, we have been able to help over 112,000 customers through our emergency hardship program and most have emerged from deferral and returned to repayment.
Coupled with this positive trend is a reduction in our 30-plus day delinquency rate. At September 30, this rate had decreased to 3.5%, down 20 basis points quarter-over-quarter and down 30 basis points year-over-year. And as Raul mentioned earlier, the October 30-plus day delinquency rate was 3.6%, also 30 basis points better than last year's level. We regard this positive trend as an indication that our customers are currently managing through the crisis and returning to repayment status.
At the same time, we continue to be extremely pleased with the credit performance of our newly originated loans. The loans we have originated since our credit tightening in mid-March have continued to trend better than 2019 levels. These results are a testament to the competitive advantage we have built through our proprietary underwriting models and technology platform. We do not need credit to be better than last year, however, and our risk team continues to analyze opportunities to open up in well-performing notes, as evidenced by the quarter-over-quarter growth we delivered in Q3.
Our annualized net charge-off rate was 10.4% for the third quarter, down from 10.6% for the second quarter. Consistent with our policy and charge-off actions we took in the second quarter, we deemed certain loans impacted by the pandemic to be uncollectible prior to reaching 120 days past due. This led to $11.2 million of additional charge-offs in the third quarter. We continue to expect elevated levels of charge-offs. However, future accelerated charge-offs are expected to be lower than in the third quarter.
Turning now to capital and liquidity. We continue to manage our funding program to maintain a liquidity runway of at least 12 months. As of October 31, total cash was $196.2 million comprised of cash and cash equivalents of $140.2 million and restricted cash of $56 million. Last week, we completed the sale to an institutional asset manager of Class C and Class D bonds that we had retained as part of our 2018-B and 2019-A asset-backed securitizations. The transaction provided us with growth capital of $39.8 million, net of fees and expenses, and reflected investor confidence in our collateral performance in our business model. We also co-sponsored a $188 million securitization by our whole loan buyer backed by loans they had previously purchased from us. While the whole loan buyer receives the economic benefit of the securitization funding, the strong investor reception the deal received pricing at 2.8% cost of funds also reflects asset-backed investor confidence in Oportun loans.
I also want to update you on our plans for whole loan sales. We have extended our current whole loan agreement through December 10, and we'll continue to sell 10% of our loans at the same price as before. During this extension period, we will evaluate our future options for selling whole loans. Given we are coming up on year-end, we may decide to pause selling whole loans. If we decide to stop selling whole loans in the future, we are comfortable holding these loans on our balance sheet, and we expect the near-term reduction in the gain on sale to be more than offset by additional interest income over time.
To evaluate our liquidity, it is also valuable to look at our cash flow statement. For the third quarter, our cash flow from operations was $45.4 million as compared to $68.6 million for the prior year period. We also continued to maintain a strong capital base and run our business at a low level of leverage. As of the end of the third quarter, we had adjusted tangible book value of $425.1 million or $15.41 per share. Our debt-to-equity ratio was 2.9x, a reduction from 3.3x the prior year.
As of October 31, 2020, we had $208 million of undrawn capacity on our $400 million warehouse line that is committed through October 2021. We believe our warehouse line, combined with our demonstrated ability to successfully place both senior and subordinate bonds will support our return to growth.
In closing, like Raul, I am very excited about the MetaBank announcement, and I'm extremely encouraged by the progress we're showing with our credit outcomes, the growth prospects of our products and the health and stability of our balance sheet. While I will not be providing financial guidance at this time due to the ongoing pandemic, our long-term outlook for Oportun remains optimistic, and we see a great opportunity for growth in the months ahead.
With that, I will now turn the call back over to Raul.
