| IRS990ScheduleD/SupplementalInformationDetail/ExplanationTxt | 1 | Income tax benefits are recognized for income tax positions taken or expected to be taken in a tax return, only when it is determined that the income tax position will more-likely-than-not be sustained upon examination by taxing authorities. GPFD has analyzed tax positions taken for filing with the Internal Revenue Service and the State of California. GPFD believes that income tax filing positions would be sustained upon examination and does not anticipate any adjustments that would result in a material adverse effect on GPFDs financial position, results of operations or cash flows. Generally tax returns remain open for federal examination for three years and for four years for the State of California, from the date of filing. GPFDs policy is to classify income tax related interest and penalties, if any, in interest expense and other expenses, respectively. |
