(3) Marketable Securities

The Company’s marketable securities are all classified as available-for-sale within “Current Assets” in the Company’s Consolidated Balance Sheets. FASB has established three levels of inputs that may be used to measure fair value:

Level 1 Observable inputs such as quoted prices in active markets for identical assets or liabilities;

Level 2 Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and

Level 3 Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.

The Company’s marketable securities valued using Level 1 inputs include highly liquid equity securities, for which quoted market prices are available. The Company’s municipal bond portfolio is valued using Level 2 inputs. The Company’s municipal bonds are valued using a combination of pricing for similar securities, recently executed transactions, cash flow models with yield curves and other pricing models utilizing observable inputs, which are considered Level 2 inputs.

For Level 2 investment valuation, the Company utilizes standard pricing procedures of its investment advisory firm which includes various third party pricing services. These procedures also require specific price monitoring practices as well as pricing review reports, valuation oversight and pricing challenge procedures to maintain the most accurate representation of investment fair market value.

The Company accrues interest on its bond portfolio throughout the life of each bond held. Dividends from the equity securities are recognized as received. Interest, dividends and unrealized gains and losses on equity securities are recognized in “Investment income and interest expense” on the Company’s Consolidated Statements of Income. The Company recognized investment income of $178 thousand in the second quarter of 2018, which included an unrealized loss in equity securities of $459 thousand. An investment loss of $187 thousand, which included an unrealized loss in equity securities of $1.2 million, was recognized in the first half of 2018. Investment income was $672 thousand and $1.8 million in the thirteen and twenty-six weeks ended July 1, 2017, respectively.

SERP Investments

The Company also maintains a non-qualified supplemental executive retirement plan and a non-qualified pharmacist deferred compensation plan for certain of its associates which allows them to defer income to future periods. Participants in the plans earn a return on their deferrals based on mutual fund investments. The Company chooses to invest in the underlying mutual fund investments to offset the liability associated with the non-qualified deferred compensation plans. Such investments are classified as trading securities and are measured at fair value using Level 1 inputs with gains and losses included in “Investment income and interest expense” on the Company’s Consolidated Statements of Income. The changes in the underlying liability to the associates are recorded in “Operating, general and administrative expenses.”
