If someone outside all of the households pays for the common shelter item, each household
            receives ISM.
         
         If someone in one or more of the households pays for the shelter item, the remaining
            household(s) using the item receives ISM.
         
         If the individual's household does receive outside ISM in the form of a shelter item
            that is also used by another household, assume, absent evidence to the contrary, that
            the households use the shelter item equally and divide the vendor charge by the number
            of households.
         
         Assume, absent evidence to the contrary, that the household in which the individual
            lives does not receive ISM in the form of a common shelter item if the individual or any member of
            their household:
         
         
            - 
               
                  •
                  
                     has rental liability to someone in another of the households using the common shelter
                        item (assume that the rent payment includes provision of the common shelter item);
                        or
                     
                     
                   
                
             
            - 
               
                  •
                  
                     renders services to someone in another of the households that use the common shelter
                        item in return for unearned or earned remuneration in the form of shelter (assume
                        that the common shelter item is counted as income in the form of renumeration for
                        services); or
                     
                     
                   
                
             
            - 
               
                  •
                  
                     receives rent-free shelter from someone in another of the households that use the
                        common shelter item (assume that the value of the free rent includes provision of
                        the common shelter item).
