Eugene Liu is a Chinese-American resident of Los Angeles, California. He contracted with T & H Machine, Inc. (“T & H”), a manufacturer of tube mills located in Addison, Illinois, to help T & H get a contract to build a tube mill in the city of Chengdu in the People’s Republic of China. Using his business contacts in China, Liu brokered the deal and T & H landed a tube mill contract worth more than three million dollars. A dispute arose about Liu’s compensation. When the parties found themselves unable to agree, Liu filed this diversity lawsuit to be decided under Illinois law, alleging that T & H breached the contract between them, seeking $102,-902 in damages, ten percent interest as per the contract, and reasonable attorneys’ fees and costs available under the Illinois Sales Representative Act, 820 ILCS 120/1, et seq. The district court granted Liu summary judgment on all counts, awarding him $144,318 plus attorneys’ fees and costs, and T & H appeals. We affirm.
I.
In 1992 Liu undertook to assist some business contacts in China to help locate a manufacturer for a tube mill plant to be built in Chengdu. He contacted a number of tube mill manufacturers in this country, including T & H, and toured their facilities in October 1992. During his visit to the T & H plant in Addison, Illinois, Liu spoke with Water R. Heller, Sr., President of T & H, and Rabinda De, an “inside” T & H salesperson. They discussed trying to obtain a contract with a Chinese customer for T & H. That November, Liu and Heller, on behalf of T & H, met in Addison and orally contracted to pay Liu seven percent of the price of the tube steel mill if the Chengdu deal went through, although it was understood that the amount, terms, and various details of the payments were to be finalized later. Liu and De visited China later that month and met with Liu’s customer, a consortium including the China National Technical Import & Export Corporation, the Southwest Technical Import & Export Corporation and the Chengdu Cold Rolling Steel Mill (the “Consortium”) to bid for the order. During the bidding, on November 21, 1992, De reduced the Liu commission agreement (the “fall contract”) to writing on a handwritten sheet, although this writing was still not final. Liu acted in T & H’s interests in the negotiations and two days later, T & H signed an agreement (the “Chengdu contract”) with the Consortium to build a tube mill for $3,010,000. Under the fall contract, Liu was then due $210,700.
In December 1992 or March 1993 — it is not clear which — Liu returned to T & H’s plant in Addison to finalize the terms and conditions of the fall contract, which was either modified in several important respects (according to Liu) or replaced by a novation (according to T & H). Liu wanted his payments split between himself and several associates whom he said had assisted him in arranging the Chengdu contract. Pursuant to this understanding, T & H executed four documents (the “agreements to pay”), signed by Heller as President of T & H, agreeing to pay Liu $50,000, and his Hong Kong Associates as follows: Sea-lam International Co., $150,000, Sun Mean, $60,300, and Nicesun Development, Ltd., $86,400, for a total of $346,700. Payments were to be made progressively within five business days of T & H’s receipt of payment from the Consortium in connection with the Chengdu contract. Ml amounts payable were subject to a 10% per annum late fee stipulated in each document. These documents comprised part of the subsequent agreement with Liu (the “winter contract”). For the purposes of this case it does not matter whether the winter contract was a modification of the fall contract or a novation.
Thereafter, in late 1993 or early 1994, a dispute arose between Liu and Nicesun regarding the commission payments. To avoid possible duplicate liability for T & H, in April 1994 Liu and T & H agreed in
Liu sued for his unpaid commissions in October 1996, raising contract and Illinois Sales Representative Act claims. After filing the complaint, he received reassignments from Sun Mean, Sealam, and Nice-sun, giving him the right to proceed against T & H for any monies due them under the winter contract. Liu filed an amended complaint by leave of the court in January 1998, which added reference to the reassignments as well. In June 1998, the district court found for Liu, and this appeal followed.
II.
In a diversity case we apply federal procedural law and state substantive law. Dawn Equipment Co. v. Micro-Trak Systems, Inc.,
We review the district court’s grant of summary judgment de novo, Johnson v. Zema Systems Corp.,
T & H argues first that the district judge erred in granting Liu summary judgment because there was a genuine issue of material fact in dispute as to whether it had a contract with Liu and his associates at all. In determining whether a valid agreement arose between the parties, a federal court should look to the state law that ordinarily governs the formation of contracts. Gibson v. Neighborhood Health Clinics, Inc.,
Liu has produced such evidence and T & H’s rebuttal is unpersuasive. T & H says that it “specifically denied” in its pleadings that it was aware that Liu had engaged any associates to obtain the Chengdu contract and that Liu’s deposition testimony indicates that these associates came into the contract only in December, after the Chengdu contract was executed. With respect to T & H’s knowledge of Liu’s associates, a bald and unsupported denial will be insufficient to survive a summary judgment motion. See Drake v. Minnesota Mining & Mfg. Co.,
The significance of T & H’s argument about the timing of the associates’ involvement with the project is unclear. Perhaps T & H means to suggest that there was some sort of failure of consideration if the associates were involved after the Chengdu contract was complete because past consideration provided by Liu alone will not support obligations later incurred to the associates. We are not obliged to guess at a party’s meaning, however, and arguments insufficiently developed on appeal are waived. Pitsonbarger v. Gramley,
T & H appears to argue that Liu cannot assert the rights of his associates to payment under the contract.
T & H has two objections to these reassignments. First, it disputes the authority of the signatories of the reassignments and the bona fides of their notarized signatures, apparently alleging that the authenticity of the signatures could not be determined because they were signed in Chinese characters. T & H claims that because the trial court allowed the reassignments to be pled three weeks before the motions for summary judgment were required to be filed, T & H was deprived of an opportunity to develop the evidence it needed to support these challenges. T & H does not dispute that each of these assignments was delivered to T & H’s attorney within a month of their execution — that is, at the latest, by the end of September 1997, at least three months before Liu filed his amended complaint. In addition, T & H seems to misunderstand the burden of a party opposing a summary judgment motion. We must therefore restate some first principles.
Once a motion has been filed for summary judgment, the burden shifts to the non-moving party to show through specific evidence that a triable issue of fact remains on issues on which the non-movant bears the burden of proof at trial. Vector-Springfield Properties, Ltd. v. Central Illinois Light Company, Inc.,
A bald denial that the reassignments were validly executed by persons authorized to do so “could not lead a rational trier of fact to find for the non-moving party,” McClendon v. Indiana Sugars, Inc.,
T & H attacks the validity of the reassignments, further, on the grounds that they were not gifts, as the district court treated them, but “manufactured documents designed to enable [Liu] to avoid the affect [sic] of the ... documents by which he had [assigned various sums] ... to his associates.” T & H claims, somewhat mysteriously, that the reassignments were somehow contracts which failed for lack of consideration and that T & H has standing to challenge these reassignments because it was “in privity” with Liu’s associates. Liu, for his part, asserts that the reassignments were supported by adequate consideration.
A chose in action is in general assignable under Illinois law, by gift or otherwise. See Saltzberg v. Fishman,
T & H’s final argument under the contract is that there is a genuine dispute of material fact as to whether Liu waived the 10% interest provided for in the agreement to pay Nicesun. In attempting to help T & H avoid multiple liability during his dispute with Nicesun in late 1993 or early 1994, Liu had agreed to waive interest payments on the amounts due to Nice-sun if T & H deposited the disputed amounts into an escrow account. T & H admits that it never deposited any money into the escrow account, either while the dispute was occurring or after Liu assured them it was over, but, T & H says this was because it had some evidence that Liu’s representation that the matter had been resolved was untrue. The district court held that the deposit, of the funds in the escrow account was a condition precedent to the waiver of interest and therefore, since no funds were ever deposited, Liu never had any obligation to waive the interest. See Maywood Proviso State Bank v. York State Bank and Trust Co.,
T & H seems to argue that the agreement here in question involved a promise rather than a condition, although it does not say so in as many words. It points us to some testimony by one Jeffrey Bandel, which it describes as “the only evidence regarding the interest waiver issue,” and which it says the district court improperly ignored. Whether an act is necessary to the formation of the contract or to the performance of an obligation depends upon the facts of the case. Lyntel Products, Inc. v. Alcan Aluminum Carp.,
III.
The final dispute concerns attorneys’ fees and costs. Under the Illinois Sales Representative Act, 820 ILCS 12% et seq. (the “Act”), a principal who fails to pay a sales representative his commission in a timely way shall be liable for his attorneys’ fees and court costs. Id. 120/3. T & H argues that Liu was not a “sales representative” under 120/1(4) (“ ‘Sales representative’ means a person who contracts with a principal to solicit orders and who is compensated, in whole or in part, by commission.... ”). The argument is essentially, first, that Liu represented the Chinese Consortium and not T & H, and second, that his payment under the winter contract was not a commission. T & H claims that Liu “was engaged ■ by and worked on behalf of’ the Consortium rath
T & H next argues that if Liu had originally been a sales representative, he ceased to be one when, under the winter contract, his compensation was no longer expressed as a percentage of the price of the Chengdu contract because that meant that he was not being paid on commission. T & H acknowledges that the fall contract calculated his compensation as a percentage of the price of the Chengdu contract, and that provision falls within the statutory definition of commission under the Act. See 820 ILCS 120/1(1) (“ ‘Commission’ means compensation accruing to a sales representative for payment by a principal, the rate of which is expressed as a percentage of the dollar amount of orders or sales or as a percentage of the dollar amount of profits.”). T & H now asserts, however, that the winter contract calculated his compensation as a fixed amount, and removed him from the Act because he was no longer compensated on a commission basis. This argument was not raised in the district court, and is waived. Okaw Drainage Dist. of Champaign and Douglas County, Ill. v. National Distillers and Chemical Corp.,
The long and short of it is that T & H promised to pay Liu certain amounts for acting as its sales representative in arranging a three million dollar contract, and it did not keep its promise. Instead of paying what it was contractually obligated to pay, it forced Liu to sue for the monies which were clearly and unambiguously owed him under the contract. Liu is entitled to prompt payment of those monies and to his attorneys’ fees and costs under the Act.
We therefore AffiRM the judgment of the district court in granting summary judgment on all counts to Liu.
Notes
. T & H frames this argument with the claim that the Liu contract was a contract for personal services. He further argues that the obligation to perform under such a contract cannot be delegated, although the right to compensation may be assigned. The point of
. The agreements to pay were executed solely by Heller for T & H.
. And we do not appreciate being directed to read 28 pages of deposition testimony instead of being referred to the few relevant lines.
