(1) Any valid obligation not paid within the fiscal year, including valid written interagency or intra-agency service agreements for systems development, shall be encumbered for payment thereof at the end of each fiscal year in the department of administration's accounts. Except as provided in subsection (2), an appropriation shall be deemed to be encumbered at the time and to the extent that a valid obligation against the appropriation is created.

(2) An appropriation may be encumbered by a written interagency or intra-agency agreement with the department for the alteration, repair, maintenance, or renovation of a building pursuant to the provisions of Title 18, chapter 2. If the appropriation is not encumbered by a valid obligation at the end of the next fiscal year, the appropriation reverts to the fund from which it was originally appropriated.
