Our business has been and may in the future be adversely affected by volatile conditions in the financial markets and unfavorable economic conditions generally. National and global economies are constantly in flux, as evidenced by market volatility both recently and in years past. Future economic conditions cannot be predicted, and recurrent deterioration in the economies of the nation as a whole or in the Company's markets could have an adverse effect, which could be material, on our business, financial condition, results of operations and future prospects, and could cause the market price of the Company's stock to decline.
Economic conditions are currently stressed given higher interest rates and persistent inflation, although conditions appear relatively stable in most of our local markets. Adverse developments, such as, continued inflation, health epidemics or pandemics (or expectations about them) interest rate volatility, international trade disputes, oil price volatility, the level of U.S. debt, including the debt ceiling (and the potential inability to raise the debt ceiling), and global economic conditions, could depress business and/or consumer confidence levels, negatively impact real estate values, and otherwise lead to economic weakness which could have one or more of the following undesirable effects on our business:
- a rapid decrease in low-cost or noninterest bearing deposits;- a lack of demand for loans or other products and services offered by us;- an inability to retain and recruit employees due to competition for labor;- increased competition for loans or other earning assets;- a decline in the value of our loans or other assets secured by real estate;- a decline in the value of fixed-rate investment securities which could lead to a reduction in capital due to declines in other comprehensive income/(loss);- an increase in the reliance on wholesale funding;- a credit impairment of our investment securities; or - an increase in the number of borrowers who become delinquent, file for protection under bankruptcy laws or default on their loans or other obligations to us, which in turn could result in higher levels of nonperforming assets, net charge-offs and provisions for credit losses.
Changes in interest rates could adversely affect our profitability, business and prospects. Net interest income, and therefore earnings, can be adversely affected by differences or changes in the interest rates on, or the repricing frequency of, our financial instruments. Fluctuations in interest rates can affect the demand of customers for products and services, and an increase in the general level of interest rates may adversely affect the ability of certain borrowers to make variable-rate loan payments. The speed and absolute level of increase or decrease in interest rates can have a material impact on the net interest income and economic value of equity of the Bank depending on the asset liability profile at any point in time.
In addition, different parts of the yield curve could change by different amounts causing the yield curve to steepen, flatten, or invert. The continued inversion of the yield curve could further negative impact the Company's earnings over time. Changes in market interest rates could have a material adverse effect on the Company's asset quality based on borrowers' ability to repay at higher rates, loan origination volume, financial condition, results of operations, and cash flows. This interest rate risk can arise from Federal Reserve Board monetary policies, as well as other economic, regulatory and competitive factors that are beyond our control. Rising interest rates have decreased the value of the Company's held-to-maturity and available for sale securities portfolio, and certain fixed-rate loans and the Company would realize losses if it were required to sell such securities or loans to meet liquidity needs. As a result of inflationary pressures and the resulting rapid increases in interest rates over the last year, the trading value of previously issued government and other fixed income securities has declined significantly, as well as the value of certain fixed-rate loans. These securities make up a majority of the securities portfolio of most banks in the U.S., including the Company's, resulting in unrealized losses. Unaccreted unrealized losses that existed at the time securities were transferred to held-to maturity and unrealized losses on available-for-sale securities are reflected in the Company's accumulated other comprehensive income/(loss). Changes to unrealized losses after securities were transferred to held-to-maturity and unrealized losses on loans are not reflected in accumulated other comprehensive income/(loss).
Challenges in the agricultural industry could have an adverse effect on our customers and their ability to make payments to us, particularly in view of severe weather events in California and disruptions involving international trade. Difficulties experienced by the agricultural industry have led to relatively high levels of nonperforming assets in previous economic cycles. This is due to the fact that a considerable portion of our borrowers are involved in, or are impacted to some extent by, the agricultural industry. While a great number of our borrowers are not directly involved in agriculture, they would likely be impacted by difficulties in the agricultural industry since many jobs in our market areas are ancillary to the regular production, processing, marketing and sale of agricultural commodities.
The markets for agricultural products can be adversely impacted by increased supply from overseas competition, a drop in consumer demand, tariffs and numerous other factors. In recent periods in particular, retaliatory tariffs levied by certain countries in response to tariffs imposed by the US Government on imports from those countries have created a high degree of uncertainty and disruption in the agricultural community in California, due to the level of goods that are exported. The ripple effect of any resulting drop in commodity prices could lower borrower income and depress collateral values. Weather patterns are also of critical importance to row crop, tree fruit, and citrus production. A degenerative cycle of weather has the potential to adversely affect agricultural industries as well as consumer purchasing power and could lead to higher unemployment throughout the San Joaquin Valley. In recent years, the state of California experienced the worst drought in its recorded history, and it is difficult to predict if the drought will resume and how long it might last. Another looming issue that could have a major impact on the agricultural industry involves water availability and distribution rights. If the amount of water available to agriculture becomes increasingly scarce as a result of diversion to other uses or limitations on agricultural use, farmers may not be able to continue to produce agricultural products at a reasonable profit, which has the potential to force many out of business. Such conditions have affected and may continue to adversely affect our borrowers and, by extension, our business, and if general agricultural conditions decline our level of nonperforming assets could increase.
Another significant drop in oil prices could have an adverse impact on our customers and their ability to make payments to us, particularly in areas such as Kern County where oil production is a key economic driver. As we have experienced in the past, a drop in oil prices could lead to declines in property values and property taxes, particularly in Kern County, which is home to about three quarters of California's oil production. The Company does not have direct exposure to oil producers, and our exposure via loans outstanding to borrowers involved in servicing oil companies totaled only $5.3 million at December 31, 2023. However, if cash flows are disrupted for our energy-related borrowers, or if other borrowers are indirectly impacted and/or non-oil property values decline, our level of nonperforming assets and loan charge-offs could increase. Furthermore, economic multipliers to a contracting oil industry include the prospects of a depressed residential housing market and a drop in commercial real estate values.
Recent negative developments affecting the banking industry, and resulting media coverage, have eroded customer and investor confidence in the banking system. The recent high-profile bank failures involving Silicon Valley Bank, Signature Bank, and sale of First Republic Bank have generated significant market volatility among publicly traded bank holding companies and, in particular, regional and community banks like the Company. These market developments have negatively impacted customer confidence in the safety and soundness of regional and community banks. As a result, customers may choose to maintain deposits with larger financial institutions or invest in higher yielding short-term fixed income securities, all of which could materially adversely impact the Company's liquidity, loan funding capacity, net interest margin, capital and results of operations. Additionally, these recent events have, and could continue to, adversely impact the market price and volatility of the Company's common stock independent from the Company's actual underlying financial performance.
We may not be able to continue to attract and retain banking customers, and our efforts to compete may reduce our profitability. The banking business in our market areas is highly competitive with respect to virtually all products and services, which may limit our ability to attract and retain banking customers. In California generally, and in our service areas specifically, major banks dominate the commercial banking industry. Such banks have substantially greater lending limits than we have, offer certain services we cannot offer directly, and often operate with economies of scale that result in relatively low operating costs. We also compete with numerous financial and quasi-financial institutions for deposits and loans, including providers of financial services via the internet. Due to deposit declines from a higher rate environment, competition for deposits has become more fierce and new deposits generally have a higher cost. Recent advances in technology and other changes have allowed parties to effectuate financial transactions that previously required the involvement of banks. For example, consumers can maintain funds in brokerage accounts or mutual funds that would have historically been held as bank deposits. Additionally, the use of blockchain and related technology may cause further disintermediation away from banks. Consumers can also complete transactions such as paying bills and transferring funds directly without the assistance of banks. The process of eliminating banks as intermediaries, known as disintermediation, could result in the loss of customer deposits and the fee income generated by those deposits. The loss of these revenue streams and access to lower cost deposits as a source of funds could have a material adverse effect on our financial condition and results of operations.
Moreover, some customers continue to be concerned about the extent to which their deposits are insured by the FDIC. Customers may withdraw deposits in an effort to ensure that the amount they have on deposit with their bank is fully insured. The bank offers accounts to customers that provide multi-million-dollar FDIC insurance using the IntraFi network of banks to offer reciprocal fully FDIC insured accounts through the Insured Cash Sweep ("ICS") or Certificate of Deposit Account Registry System ("CDARS"). At December 31, 2023, the Bank estimates it had uninsured deposits of $816 million. Decreases in deposits may adversely affect our funding costs and net income. Ultimately, competition can and does increase our cost of funds, reduce loan yields and drive down our net interest margin, thereby reducing profitability. Competition can also make it more difficult for us to continue increasing the size of our loan portfolio and deposit base and could cause us to rely more heavily on wholesale borrowings which are generally more expensive than retail deposits.
We may not be able to continue to attract and retain employees, and our efforts to compete for talent may reduce our profitability. The Company recognizes that community banking is based on relationships and a core part of the Company's service strategy is to recruit and develop employees that build these relationships with customers, vendors, and other employees. In addition to offering a competitive base salary or wage, the company offers comprehensive benefits, including training. Due to continued turnover, the Company increased its minimum wage to $20 per hour effective January 1, 2022, in an effort to attract and retain employees at all levels. The Company's employees are critical to the Company's ability to develop and grow relationships with its clients. Recruiting talent within the Company's footprint has always been a fundamental strategy whenever possible but has been recently complemented with offering existing and new employee's opportunities for remote and/or hybrid work arrangements if possible. However, we recognize that competition for talent by both banks and non-banks is fierce and that our overall expenses may be negatively affected by higher per employee costs or by higher-cost temporary staff or consultants. The competitive market for talent could also result in gaps of experience in certain areas or lower staffing levels which could result in a reduced ability to serve our customers.
The value of the securities in our investment portfolio may be negatively affected by market disruptions, adverse credit events or fluctuations in interest rates, which could have a material adverse impact on capital levels. Our available-for-sale investment securities are reported at their estimated fair values, and fluctuations in fair values can result from changes in market interest rates, rating agency actions, issuer defaults, illiquid markets and limited investor demand, among other things. Under current accounting rules we directly increase or decrease accumulated other comprehensive income in shareholders' equity by the amount of the change in fair value, net of the tax effect. Because of the size of our fixed income bond portfolio relative to total assets, a relatively large increase in market interest rates, in particular, could result in a material drop in fair values and, by extension, our capital. For the year ended December 31, 2023, we had total other comprehensive gains of $20.6 million, net of tax, primarily as a result of a decline in unrealized losses in our securities portfolio. The Company has a significant amount of Collateralized Loan Obligations; a change in credit events, demand or other factors could decrease the spread to the index which could have a negative impact in the value of those bonds. Non-government and non-US agency investment securities that have an amortized cost in excess of their current fair value at the end of a reporting period are also evaluated for potential credit impairment. If such credit impairment is indicated, the difference between the amortized cost and the fair value of those securities will be recorded as a charge in our income statement, which could also have a material adverse effect on our results of operations and capital levels.
We are exposed to the risk of environmental liabilities with respect to properties to which we obtain title. Approximately 86.7% of our loan portfolio at December 31, 2023, consisted of real estate loans. In the normal course of business we may foreclose and take title to real estate collateral and could be subject to environmental liabilities with respect to those properties. We may be held liable to a governmental entity or to third parties for property damage, personal injury, investigation and clean-up costs incurred by these parties in connection with environmental contamination or may be required to investigate or clean up hazardous or toxic substances, or chemical releases at a property. The costs associated with investigation or remediation activities could be substantial. In addition, if we are the owner or former owner of a contaminated site, we may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination emanating from the property. These costs and claims could adversely affect our business and prospects.
