erty a lateral transfer at the same salary and benefits and with comparable responsibilities, and had resorted to termination only when Flaherty declined its offer. Because we agree that Flaherty has not established a prima facie case under the ADEA, we affirm the district court’s judgment. We also affirm the imposition of Fed.R.Civ.P. 11 sanctions on Flaherty’s counsel for pursuing a common law retaliatory discharge claim without exhausting the administrative remedies afforded under Illinois law.
I. BACKGROUND
Our factual discussion is taken largely from the statements submitted by the parties pursuant to Local Rules 12(m) and 12(n) of the United States District Court for the Northern District of Illinois. But this case, like so many others of recent vintage (see Waldridge v. American Hoechst Corp., 24 F.3d 918, 921-22 (7th Cir.1994) (compiling cases)), presents several problems under those rules. GRI submitted a lengthy Rule 12(m) statement along with its motion that fully complied with the local rule. The factual averments in GRI’s statement were supported by citations to deposition transcripts, which were attached, and to affidavits of company employees. Yet in response, Flah-erty submitted no affidavits, nor did he attach supplemental deposition transcripts, although his Rule 12(n) statement referenced pages that had not been provided by GRI. Thus, as the district court noted, “except in those cases where [Flaherty] fortuitously cites to deposition testimony and affidavits tendered by GRI, we are unable to verify the evidence [he] occasionally references.” (R. 57 at 2 n. 1.) Equally problematic, Flaherty often asserted in response to GRI’s Rule 12(m) statement that a particular fact was disputed without referencing the evidence that would show the nature of that dispute. That is insufficient, as the local rule requires the non-movant to support its disagreement by making “specific references to the affidavits, parts of the record, and other supporting materials” that allegedly establish a factual dispute. Local General Rule 12(n), Northern District of Illinois. We have repeatedly upheld this requirement, indicating that in the absence of such evidence, “district courts are not obliged in our adversary system to scour the record looking for factual disputes.” Waldridge, 24 F.3d at 922; see also Valenti v. Qualex, Inc., 970 F.2d 363, 369 (7th Cir.1992). They instead may deem the fact admitted. Waldridge, 24 F.3d at 922-23. That having been said, we proceed to describe the factual background of this dispute.
GRI is a not-for-profit corporation engaged in research and development for the benefit of its natural gas industry members. It hired Flaherty as a senior scientist on May 27, 1983, when Flaherty was forty-two years of age. GRI promoted Flaherty in 1985 and again in 1987, and he ultimately became the director of its Industrial Utilization Research Group, where he had primary responsibility for the group’s management and strategy planning. In April 1989, however, after an investigation into allegations that Flaherty had made racially derogatory remarks to subordinates, GRI removed Flaherty from his director’s position and made him a principal scientist in charge of special projects. By this demotion, GRI sought to relieve Flaherty of his supervisory responsibilities while continuing to utilize his technical expertise. As a principal scientist, Flaherty reported to William Burnett, a GRI senior vice president.
In February 1990, Flaherty became the principal scientist in charge of program quality. Although he still reported to Burnett, Flaherty now worked daily with Irvine Solo-mon, who was in charge of GRI’s quality program. Flaherty managed two contracts for GRI in his capacity as principal scientist for program quality. Their value was between $300,000 (GRI’s estimate) and $1.25 million (Flaherty’s estimate).
In November 1991, GRI’s Board of Directors and its management decided to reduce expenses , through a reduction in the company’s work force. GRI’s president, Stephen Ban, directed all vice presidents to develop staff-reduction plans within their areas of responsibility. Burnett therefore met with the vice presidents in the research and development area and determined to eliminate four existing positions from his staff by
