7. Fair Value of Financial Instruments

 

As required by the Financial Instruments topic of the FASB ASC, the following summarizes required information about the fair value of certain financial instruments for which it is currently practicable to estimate such value. None of the financial instruments are held or issued for trading purposes. The carrying amounts and fair values of the Company’s financial instruments are as follows:

 

    December 30, 2017     December 31, 2016  
    Carrying     Fair     Carrying     Fair  
    Amount     Value     Amount     Value  
Cash and cash equivalents   $ 891,488     $ 891,488     $ 846,883     $ 846,883  
Restricted cash   $ 271     $ 271     $ 113     $ 113  
Marketable securities   $ 1,421,720     $ 1,421,720     $ 1,480,237     $ 1,480,237  

 

For certain of the Company’s financial instruments, including accounts receivable, loan receivable, accounts payable and other accrued liabilities, the carrying amounts approximate fair value due to their short maturities.
