(1) | The fair value of marketable securities with contractual maturity dates within one year are included in marketable securities and those with contractual maturity dates greater than one year are included in other assets on the Consolidated Balance Sheets. Corporate debt securities were measured at fair value using a market approach utilizing observable prices for identical securities or securities with similar characteristics and inputs that are observable or can be corroborated by observable market data.
Net unrealized losses on available-for-sale securities totaling $27 and $11 were included in accumulated other comprehensive loss on the Consolidated Balance Sheet as of December 28, 2016 and December 30, 2015, respectively. The following tables summarize the gross unrealized losses and fair values for those investments that were in an unrealized loss position as of December 28, 2016 and December 30, 2015, aggregated by investment category and the length of time that individual securities have been in a continuous loss position:

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 marketable 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 December 28, 2016 and December 30, 2015, the declines in the market value of our marketable securities investment portfolio are considered to be temporary in nature. Other Financial Instruments The carrying value of our financial instruments, including accounts receivable, accounts payable, and accrued expenses as of December 28, 2016 and December 30, 2015 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 fiscal 2016, 2015 and 2014.
