Analyst · Stifel, Nicolaus
Thank you, Mike. Good afternoon, everyone. We're again satisfied with our quarter, and we are very pleased to have set a new net income record in 2012. You'll notice on Slide 6 where my comments will begin that our loans now exceed the 2010 levels by $66 million after a decline in 2011. The addition of $189 million in loan outstandings during 2012 pushed our loan-to-asset ratio to a healthy 67% and positions us well for 2013.
The composition of our loan portfolio on Slide 7 allows for pricing power and continues to produce nearly a 5% yield. Without Shelby County's fair value accretion this quarter of $1.3 million, the loan yields totaled 4.79%. Last quarter's adjusted yield was 14 basis points higher, totaling 4.93%.
We're particularly pleased with the growth in the commercial and industrial loan category as this now totals 22.9% of total loans and has increased from this time last year by $97 million per John Martin's detail on Page 21 of the presentation, which he'll get to a little later.
On Slide 8, our bond portfolio continues to perform well, producing higher-than-average yields with a moderately longer duration than peer. Our 3.7% yield compares favorably to peer averages of approximately 2.85 and our duration is just 8 months longer, totaling 3.7 years.
Our bond portfolio balances peaked in the first quarter of 2012, totaling $960 million and has declined each of the last 3 quarters. We anticipate having a slightly smaller bond portfolio throughout 2013. However, like this quarter, the yield should rise as our runoff includes lesser-yielding bonds than our core portfolio.
2013 maturities are estimated to total $154 million with an average yield of 3.13% and we do plan to shift those earnings assets from bonds into higher-yielding loans as we progress throughout 2013. The net unrealized gain in the portfolio totaled $39.6 million, still at healthy levels, creating flexibility as we move through the year.
Now turning to Slide 9. Non-maturity deposits on Line 1 increased during the year by $283 million as we continue to focus our deposit growth efforts on core operating accounts as commercial and retail customers. Our borrowings declined by $118 million during the year, and we are really only using those inexpensive liabilities as ways to lengthen liabilities for ALCO reasons where appropriate.
Tangible common equity continues to grow nicely. Our tangible book value now totals $10.95, and our stock is trading at approximately 130% of tangible book value.
The mix of our deposits on Slide 10 continues to improve, and our total deposit expense is now just 50 basis points. Our year-to-date 2012 costs at 57 basis points is 30 basis points better than 2011.
Our regulatory capital ratios on Slide 11 are well above the OCC and the Federal Reserve's definitions of well capitalized and all Basel III proposed minimums. We are pleased that Tier 1 common equity on Line 4 now totals 9.6% and tangible common equity on Line 5 now totals 7.5%.
We also stated in the last quarter's call that it was our desire to begin paying down our SBLF capital as we've moved into 2013, given the strength of our common equity and the high coupon that SBLF requires. In an 8-K filed on January 8 of this year, we announced the redemption of 25% of our outstanding SBLF shares, totaling $22,695,000. The pace of future redemptions will be primarily governed by the strength of our earnings, but we're anticipating another like payment in the second half of 2013.
The corporation's net interest margin on Slide 12 totaled 4.1% for the quarter. But more importantly, our net interest income improved by $9 million year-over-year. Fair market value accretion resulting from our Shelby County acquisition accounted for $4.6 million of the $9 million annual increase as various substandard SCB credits were paid in full. We are very pleased that our net interest margin, when adjusted for fair value accounting, remained strong all year and averaged 4%.
Total noninterest income on Slide 13 continues to improve and remains additive to operating income. The improvements were primarily fueled by mortgage gains on Line 6, which increased by $3.2 million or 43%. Additionally, the corporation experienced significant improvements in insurance commission income, electronic card fee income, cash surrender value of life insurance and our derivative income from loan level hedge activity, which is highlighted in the other category on Line 9.
Noninterest expense totaled $137.1 million for the year, an increase of less than 1%. Various categories on Slide 14 were mixed as line items like other real estate and FDIC expenses declined by $4.4 million, yet salary and benefit expenses increased by $4.7 million. Overall, and especially given the $1 million increase in commission expense paid to mortgage originators for an exceptional year and the $1.8 million increase in benefits expense due to changes in the discount rate on our frozen pension plan and increased health insurance claims expense, we are pleased with the expense management for 2012.
Please turn to Slide 15. Our pretax pre-provision run rate on Line 4, as presented without fair market value accounting gains on Line 6, totaled $69.2 million for the year. The $8.9 million increase follows a $6.6 million increase from the prior year. These double-digit percentage increases are also finding their way to our bottom line as provision expense continues to decline on a year-over-year basis.
As Mike mentioned, in 2007, our net income totaled $31.6 million, which, until this year, represented the best net income year in the corporation's 119-year history. So as Mike mentioned, we're very pleased to have established a new high of over $40 million on Line 10 in 2012.
Our employees and management teams are very pleased with our core EPS trend line, on Slide 16, and we hope that, as shareholders, you are as well.
Now John Martin, our Chief Credit Officer, will discuss why our provision expense and OREO expense continued to decline, and he will discuss the improvements in classified assets, which provide renewed capital management flexibility.
