brokered home equity lines of credit ) .
as part of our overall risk analysis and monitoring , we segment the home equity portfolio based upon the loan delinquency , modification status and bankruptcy status , as well as the delinquency , modification status and bankruptcy status of any mortgage loan with the same borrower ( regardless of whether it is a first lien senior to our second lien ) .
in establishing our alll for non-impaired loans , we utilize a delinquency roll-rate methodology for pools of loans .
the roll-rate methodology estimates transition/roll of loan balances from one delinquency state to the next delinquency state and ultimately to charge-off .
the roll through to charge-off is based on our actual loss experience for each type of pool .
each of our home equity pools contains both first and second liens .
our experience has been that the ratio of first to second lien loans has been consistent over time and the charge-off amounts for the pools , used to establish our allowance , include losses on both first and second lien loans .
generally , our variable-rate home equity lines of credit have either a seven or ten year draw period , followed by a 20-year amortization term .
during the draw period , we have home equity lines of credit where borrowers pay either interest only or principal and interest .
we view home equity lines of credit where borrowers are paying principal and interest under the draw period as less risky than those where the borrowers are paying interest only , as these borrowers have a demonstrated ability to make some level of principal and interest payments .
the risk associated with the borrower 2019s ability to satisfy the loan terms upon the draw period ending is considered in establishing our alll .
based upon outstanding balances at december 31 , 2016 , the following table presents the periods when home equity lines of credit draw periods are scheduled to end .

based upon outstanding balances , and excluding purchased impaired loans , at december 31 , 2016 , for home equity lines of credit for which the borrower can no longer draw ( e.g. , draw period has ended or borrowing privileges have been terminated ) , approximately 3% ( 3 % ) were 30-89 days past due and approximately 6% ( 6 % ) were 90 days or more past due , which are accounted for as nonperforming .
generally , when a borrower becomes 60 days past due , we terminate borrowing privileges and those privileges are not subsequently reinstated .
