| |  | | (2)__Using the enhanced basic support entitlement, a |  | total support obligation for each child must be |  | determined pursuant to subsection 3.__The amount is |  | the enhanced total support obligation. |

 |  | | (3)__Using the enhanced total support obligation, a |  | theoretical parental support obligation must be |  | determined for each party as though the party were |  | the nonprimary residential care provider under |  | subsection 4. |

Current child support |  | guidelines are silent on this matter. |

 |  | |  | The bill provides a presumptive calculation in cases where |  | the parents provide substantially equal care for the child. |  | Current child support guidelines permit a deviation but |  | provide no guidance for a presumptive determination of the |  | amount of the deviation. | 
 | 
 
 
 |  | |  | The presumptive calculation contains a recognition that when |  | both parents have substantial residential responsibility and |  | each provides a home for the child, the child expenditure is |  | likely to be significantly greater than it would be if the |  | child were living primarily with one parent.  The 1.5 |  | multiplier in the calculation takes into account the increased |  | costs of 2 households providing shared residence. |
