Financial Instruments with 
Off-Balance
 Sheet Risk
The Company is a party to 
stand-by
 letters of credit. The Company’s exposure to credit loss for 
stand-by
 letters of credit is represented by the contractual amounts of these instruments. The Company uses the same credit policies in making conditional obligations as it does for 
on-balance
 sheet instruments. Total conditional commitments under letters of credit as of December 30, 2018 and December 31, 2017 are $48.1 million and $46.7 million, respectively, and relate to the Company’s insurance programs and supply chain center leases. The Company has also guaranteed lease payments related to certain franchisees’ lease arrangements. The maximum amount of potential future payments under these guarantees was $2.4 million and $1.5 million as of December 30, 2018 and December 31, 2017, respectively.
