In theory, the corridor method smooths out the state's contributions even more than standard accounting practices would allow, but that wasn't why the state adopted it. In 2002, then-Gov. Parris N. Glendening flat-funded the state's pension contributions in his budget proposal despite the need, under the actuarial method, to increase them. The legislature cannot increase spending in a governor's budget, so it couldn't make up for the under-funding. But what it could do was adopt a new funding theory that had been floating around Annapolis, which had the effect of making the problem go away, at least on paper.
