Thank you, Aaron. I would like to begin by providing an overview of the impact on our financial statements of the ColoEast and Southern Transportation Insurance acquisitions. As part of the ColoEast acquisition on August 1, we acquired loans with an unpaid principal balance of $473 million and recorded a purchase discount of $12 million, reflecting a fair value price of 97.5%. We assumed $653 million of deposits. This included $445 million of transaction accounts and $208 million of time deposits and it roughly doubled our balances of noninterest-bearing demand accounts to $340 million. We recorded a core deposit intangible of $7.2 million that will be amortized over 10 years utilizing the sum-of-the-years'-digits method. We assumed junior subordinated debentures with a face value of $11.9 million. These instruments mature in 2035 and 2037, and they bear interest at an average of LIBOR plus 171 basis points. We recorded these debentures after estimated fair value of $7.7 million. We expect our accounting costs to be LIBOR plus 475 basis points. We assumed TARP securities with a face value of $10.5 million with $4.6 million of accrued and unpaid dividends as of the acquisition date. We paid off the TARP securities and accrued dividends on August 31. The accrued dividend for the month of August prior to redemption of $104,000 was recorded as a dividend on preferred stock. We incurred $1.6 million gross or $1.4 million tax effective of ColoEast acquisition-related expenses in the third quarter for employee severance, system contract termination, accounting, consulting, valuation and legal work. We recorded $12.1 million of provisional amount of goodwill. Together with a core deposit intangible that's resulted in dilution of tangible book value per share of $1.07. We expect to meet or exceed our targeted cost savings of approximately $5 million phased in over the upcoming year following the acquisition.
Regarding the acquisition of Southern Transportation Insurance company on September 1, we paid [ $2 point ] million of cash and an asset purchase to acquire the business. The purchase resulted in $600,000 of goodwill and $1.6 million of customer intangibles.
Slides 7 and 8 as well as the tables attached to the earnings release present the current historic mix of the loan portfolio. As Aaron mentioned, organic loan growth, excluding ColoEast, was $89 million or 6.3% this quarter. The breakdown of this organic growth includes a net increase of $31 million of a commercial finance portfolio and a $58 million increase in the community banking portfolio, including a $37 million increase on our mortgage warehouse portfolio. The acquired ColoEast portfolio included farmland and agricultural production loans. Starting this quarter, we've broken out the ag loans on Slide 7 on the investor deck, which shows as of this quarter end, we have $139 million of loans in farmland and $125 million of agricultural production loans.
Slides 8 through 10 present trend information for net interest margin. Yield on loans this quarter was 7.42%, a decrease of 108 basis points from the second quarter, again due substantially of a change in the loan mix resulting from the Colorado acquisition. The adjusted yield on loans, which excludes the impact of approximately $4.7 million of purchase loan discount accretion we recorded during our third quarter, was down 70 basis points to 7.10%. As of September 30, we had $18 million remaining in loan purchase discount, of which we currently expect $15.4 million to accrete into income over the remaining lives of the acquired loans. Of this accretable amount $8.6 million is expected to accrete by the end of 2017. Prior to acquisition, the ColoEast loans were yielding approximately 5.5%.
Regarding interest expense, the cost of total deposits and total funds improved, decreasing by 6 basis points and 7 basis points this quarter to 57 basis points and 61 basis points, respectively. Contributing to this improvement was the lower cost deposit base assumed from the Colorado acquisition.
Net interest margin remained strong at 5.79%. Adjusted net interest margin, which excludes loan discount accretion, was 5.53% for the quarter, a decrease of 45 basis points from the previous quarter due to the factors I just mentioned. We earned noninterest income of $6.1 million for the quarter ended September 30. Excluding the impacts of gains and losses on sale of loans, securities and REO adjustments, noninterest income increased $1.2 million from the prior quarter. Most of this increase is due to additional fees associated with the growth in consumer loan and deposit accounts in conjunction with acquisition of ColoEast. Noninterest income in the third quarter also includes $1.6 million in asset management fees earned by Triumph Capital Advisers. TCA now manages approximately $1.47 billion of CLO assets, earning approximately 31 basis points on average in management fees. TCA has also been engaged as the staff and services provider to Trinitas Capital Management, which is the named asset manager for a $407 million CLO issued in June and another $409 million CLO issued in September.
As staff and services provider, TCA performs certain middle and back-office functions and earns a 26 basis point fee based on the assets in the respective CLOs. In total, TCA now provides services for approximately $2.3 billion in fee-generating CLO assets, consisting of both CLOs for which we're asset managers and CLOs for which we provide staff and services for a fee. Our annualized revenue earned from these fee-generating CLO assets equals approximately 30 basis points of such assets.
Triumph also holds minority investments of $3.4 million in the subordinated notes issued by the Trinitas Capital Management CLOs. At September 30, Triumph also holds a $10.4 million equity investment in one CLO warehouse, down from $17.3 million as of June 30. These CLO warehouse investments earned noninterest income of $657,000 in the third quarter and $774,000 in the second quarter of this year.
For the third quarter of 2016, noninterest expense increased $5.5 million from the prior quarter to $25.8 million. Our noninterest expense this quarter includes $1.6 million of expense associated with the ColoEast acquisition activities. The remaining increase is primarily due to the cost associated with incremental additions of the ColoEast personnel, facilities and activities into our operations. Our adjusted efficiency ratio improved 2.5% from the prior quarter, and our adjusted ratio of net noninterest expense to average assets decreased 70 basis points from the prior quarter to 3.15%.
As mentioned previously, we expect to meet or exceed our cost savings targets for the ColoEast operations in terms of both amount and timing, but these savings are just now beginning to show up in our results.
Slide 13 presents our asset quality ratios, all of which increased quarter-over-quarter due to the addition of loans acquired from ColoEast as well as deterioration experienced in other parts of our loan portfolio. Past due to total loans increased 106 basis points to 3.86% at September 30. Our past due loans increased $36.1 million from $39.5 million at June 30 to $75.6 million at September 30. Approximately $19.2 million or 53% of the quarterly increase was due to past due loans in acquired ColoEast loan portfolio. Nonperforming loans, which also includes TDRs and factored receivables greater than 90 days past due, increased by $22 million to $44 million, and as a percent of total loans increased 69 basis points to 2.25% as of September 30. Of the $44 million balance of nonperforming loans at September 30, $7.4 million are loans acquired from ColoEast, which were brought over with $1.2 million of purchase discount and $24 million of commercial finance loans, including $2.1 million of the factored receivables. Most of the increase in nonperforming loans this quarter is due to three credit relationships that have deteriorated and were placed on nonaccrual. Nonperforming assets, which also includes OREO and other repossessed assets, increased $24.3 million to $52.7 million this quarter, and as a percent of total assets increased 45 basis points to 2.05% as of September 30.
Our provision for loan loss expense this quarter was $2.8 million due in part to general reserves for organic loan growth experienced during the quarter, but primarily due to $700,000 of specific allocations on the two impaired loans and a $1.4 million partial charge-off of another. For the September quarter, charge-offs net of recoveries were $1.7 million or 10 basis points of average loans. Our ALLL increased $1.1 million to $14.9 million, but as a percent of total loans decreased 22 basis points this quarter to 76 basis points as of September 30. As a reminder, loan loss reserves related to the acquired ColoEast loans were not carried over to Triumph upon acquisition as the loans are measured at their acquisition date fair values, resulting in a $12 million purchase discount on those loans, which includes the impact of credit inefficiencies and expected future losses. The combined balance of our total unamortized purchase discount and ALLL as a percentage of total loans is 1.7%, which is an alternative view of our credit risk coverage.
With that, I'd like to turn the call back over to Aaron.
