Choice "C" is correct. Reciprocal interfund activity for the City of Curtain is $5,000. Reciprocal interfund activity includes interfund loans and interfund services provided and used. Billing by the internal service fund to a department financed by the general fund for services rendered is the only transaction meeting this definition. Nonreciprocal transfers include interfund transfers (which are displayed as either other financing sources or uses on the governmental fund financial statements or purely as transfers in proprietary fund financial statements) and interfund reimbursements (which are not shown on the face of the financial statements).Choice "d" is incorrect. This response incorrectly combines a routine transfer (nonreciprocal activity) of $50,000 with a $5,000 reciprocal transfer (an internal service fund billing). Choice "b" is incorrect. This response incorrectly classifies a transfer (nonreciprocal activity) of $200,000 as a reciprocal transfer. Reciprocal transfers are defined above as payments for services provided and used, and loans. Internal capitalization of a new fund is not considered reciprocal. Choice "a" is incorrect. This response incorrectly combines a both a routine transfer (nonreciprocal activity) of $50,000 and a nonroutine transfer (also nonreciprocal) of $200,000 with a $5,000 reciprocal transfer (an internal service fund billing).
