these vehicles may be available to us, as of October 1, 2019, we had chosen not to enter into any hedging contracts due to pricing volatility, excessive risk premiums, hedge inefficiencies or other factors. Commodities for which we have not entered into contracts can be subject to unforeseen supply and cost fluctuations, which at times may be significant. Additionally, the cost of commodities subject to governmental regulation, such as dairy and corn, can be especially susceptible to price fluctuation. Commodities we purchase on the international market may be subject to even greater fluctuations in cost and availability, which could result from a variety of factors, including the value of the U.S. dollar relative to other currencies, international trade disputes, tariffs and varying global demand. We may or may not have the ability to increase menu prices or vary menu items in response to food commodity price increases. For the third quarters of both fiscal 2019 and 2018, a hypothetical increase of 1% in food costs would have negatively impacted cost of sales by $1.3 million.
We are exposed to market risk from interest rate changes on our funded debt. This exposure relates to the component of the interest rate on the New Facility that is indexed to market rates. Based on outstanding borrowings at October 1, 2019 and January 1, 2019, a hypothetical 1% rise in interest rates would have increased interest expense by $3.4 million and $100,000, respectively, on an annual basis. (See Note 6 of Notes to Condensed Consolidated Financial Statements in Part I, Item 1 of this report for further discussion of our long-term debt.)
We are also subject to market risk related to our investments in variable life insurance contracts used to support our non-qualified executive deferred compensation plan, to the extent these investments are not equivalent to the related liability. In addition, because changes in these investments are not taxable, gains and losses result in tax benefit and tax expense, respectively, and directly affect net income through the income tax provision. Based on balances at October 1, 2019 and January 1, 2019, a hypothetical 10% decline in the market value of our deferred compensation asset and related liability would not have impacted income before income taxes. However, under such scenario, net income would have declined by $1.7 million and $1.5 million at October 1, 2019 and January 1, 2019, respectively.
Item 4. Controls and Procedures.
Evaluation of Disclosure Controls and Procedures
We have established and maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only a reasonable assurance of achieving the desired control objectives, and management was necessarily required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of October 1, 2019.
Changes in Internal Control over Financial Reporting
There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) during the fiscal quarter ended October 1, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
