Order unanimously reversed on the law with costs and petitions granted in accordance with the following Memorandum: "In determining whether [petitioner's] initial burden was established, the court was obliged to consider all of the evidence, including the proof adduced by [respondents]" (National Bank v. Systems Home Improvement, 69 A.D.2d 557, 562, affd 50 N.Y.2d 814). When respondents presented their appraisal evidence after the court reserved decision on the motion to dismiss at the end of petitioner's case, they took "`the chances of supplying the deficiencies of the [petitioner's] case'" (Bopp v. New York Elec. Vehicle Transp. Co., 177 N.Y. 33, 35). The testimony and appraisal report of respondents' expert is "tantamount to and should be deemed a concession that the assessments * * * should be reduced by the amounts stated in [the] report" (Matter of Wantagh Racquet Sports v. Board of Assessors, 133 A.D.2d 766, 768, lv denied 70 N.Y.2d 614). Respondents' expert testified and his report states that the final valuations of the property on December 1 of the years 1985 through 1988 were $14,000,000, $14,500,000, $14,500,000, and $15,000,000. It was stipulated that the equalization rates for those years were 27.95, 100.00, 99.19, and 91.55. Thus, we order that the assessments for each of the four years under review be reduced to $3,913,000, $14,500,000, $14,382,550, and $13,732,500.
