Realized gains and losses are determined on a specific identification method and are included in other income, net on the Condensed Consolidated Statements of Income.

The estimated fair value of our investments in corporate debt securities that are accounted for as available-for-sale securities are all due within one year and are included within marketable securities on the Condensed Consolidated Balance Sheets.

We periodically review our marketable securities for other-than-temporary impairment. We consider factors such as the duration, severity and the reason for the decline in value, the potential recovery period and our intent to sell. For our debt securities, we also consider whether (i) it is more likely than not that we will be required to sell the debt securities before recovery of their amortized cost basis, and (ii) the amortized cost basis cannot be recovered as a result of credit losses. As of June 28, 2017 and December 28, 2016, the declines in the market value of our marketable securities investment portfolio were considered to be temporary in nature.

Other Financial Instruments

The carrying value of our other financial instruments, including accounts receivable, accounts payable, and accrued expenses as of June 28, 2017 and December 28, 2016 approximated their fair value due to the short-term nature of these financial instruments.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

Assets and liabilities that are measured at fair value on a non-recurring basis include our long-lived assets and indefinite-lived intangible assets. There were no impairments recognized during thethirteen and twenty-six weeks endedJune 28, 2017 and June 29, 2016.
