Deutsche Bank was a serious company in business with Donald Trump to make money, defense attorney Jesus Suarez said during his cross examination of former Deutsche Bank executive Nicholas Haigh.

At the height of its relationship with the Trump Organization the company loaned Trump over $378 million, and failed to commission independent appraisals of Trump's properties, Haigh acknowledged. While the bank listed lower estimates for the value of Trump's assets year after year, it continued to do business with Trump and his company.

"We ... the bank hadn't done all the due diligence one would do in the sense of the opinion of value you see in an appraisal," Haigh said, at one point agreeing with the defense's characterization that the bank's internal value services group conducted "sanity checks'' on the numbers.

The direct examination of Haigh by state attorney Kevin Wallace also left a central question about Deutsche Bank's activity unanswered.

In a letter to the court and in previous arguments, lawyers for the attorney general suggested that Haigh might have turned away Trump's business if he had known that Trump's assets were inflated in value.

"As this Court noted during summary judgment arguments, Mr. Haigh testified during OAG's investigation that he may not have authorized lending to the borrower if he had at that time been aware of the inflated asset values contained in Mr. Trump's SFCs [statements of financial condition]," a lawyer for the attorney general wrote to the court in a letter last week.

Wallace never directly posed the hypothetical to Haigh during his direct examination, leaving the question unresolved.

Court subsequently adjourned for the day, with Suarez telling the court he plans to continue his cross examination of Haigh through Thursday afternoon.

Former president Donald Trump and his company bid $1 billion in 2014 in an attempt to purchase the Buffalo Bills football team.

The only problem was that Trump needed a bank to help finance his bid.

Former Deutsche Bank executive Nicholas Haigh testified that when Trump turned to his bank for help, bank executives declined, fearing it would increase their financial exposure to Trump.

"Deutsche Bank was not willing to increase its credit exposure to Donald Trump at that time," Haigh said.

But the bank was still willing to help Trump by sending a letter to support his bid, according to Haigh -- on the condition that Trump Organization controller Jeffrey McConney certify that the company was still in compliance with the covenants of the three outstanding loans the bank had given Trump.

McConney verified that Trump had over $300 million in liquid assets in 2014, and that it suffered no material decrease in the value of his illiquid assets, according to a document entered into evidence today.

With that verification, Deutsche Bank issued a letter that Trump had the "financial wherewithal" to fund his bid.

Trump's effort to purchase the Bills was ultimately unsuccessful.

When Donald Trump negotiated a $125 million loan from Deutsche Bank related to his Trump National Doral golf club, the former president agreed to maintain a minimum net worth of $2.5 billion as a condition of the loan, former bank executive Nicholas Haigh testified.

The loan memorandum prepared by Deutsche Bank included a covenant that the "Guarantor shall maintain a minimum net worth of $2.5 billion excluding any value related to the Guarantor's brand value," according to a document marked as evidence today.

The New York attorney general alleges that Trump's actual net worth at the time of the loan agreement was only $1.5 billion, an amount that would have triggered a default.

Retired Deutsche Bank executive Nicholas Haigh testified that he was involved in the decision to set the $2.5 billion figure, which he believed would protect the bank from exposure if the property failed or the broader market declined.

"It was set in order to make sure the bank was fully protected under adverse market conditions," Haigh testified.

To calculate Trump's net worth, Deutsche Bank looked at what Haigh described as Trump's four "trophy properties," all in Manhattan: Trump Tower, 40 Wall Street, Trump Park Avenue, and Niketown -- a ground lease for a property adjoining Trump Tower.

Since the properties themselves were not provided as collateral for the loan, Deutsche Bank did not commission independent appraisals for the properties, and instead used a modified version of Trump's own numbers.

"The bank normally only commissions appraisals on assets taken as collateral," Haigh said.

Deutsche Bank adjusted their assessment in 2012, when they learned of a separate appraisal of Trump Tower that offered a lower value of the property than what Trump had provided.

"The bank felt that it had an independent view on the value of the asset," Haigh said of the appraisal that prompted his bank to lower their value for Trump Tower from $1.2 billion to $992 million.

Deutsche Bank relied on the strength of Donald Trump's "financial profile" when deciding to loan the former president roughly $125 million related to the purchase of the Trump National Doral golf club in 2011, according to retired Deutsche Bank executive Nicholas Haigh.

Haigh testified that because Trump used the golf course and spa as collateral -- relatively "unusual" assets that Deutsche Bank would struggle to sell in the event of a foreclosure -- the bank leaned on the strength of Trump's larger portfolio.

"[Trump] is guaranteeing he will repay our loan -- all the money due on the loan," Haigh said about the terms of the loan. "He is also guaranteeing if the result is losing money, he will pay the cost of that shortfall."

Haigh said that he personally reviewed Trump's statement of financial condition when determining whether to sign off on the loan.

"My conclusion was the client owned a lot of real estate, which was not surprising," Haigh said about his findings after reading Trump's financial statement.

Previous witnesses in the trial have offered insights into how Trump's annual financial statement was drafted, finalized, and provided to banks to fulfill loan obligations. Haigh is the first witness to testify from the perspective of the banks, which considered the statements when deciding whether to do business with Trump.

Donald Trump's lawyers abruptly stopped the testimony of their first expert witness -- who was expected to testify for a full day or two -- after Judge Engoron limited the topic areas of his testimony.

Steven Witkoff, a real estate investor and longtime friend of Trump's, was brought into court by the defense team to testify that Trump's Doral golf club was undervalued in Trump's financial statements.

But Judge Engoron sustained an objection from the state barring any testimony about the valuation of Doral, significantly limiting Witkoff's testimony and appearing to hamper the defense strategy proposed by Trump's attorney Chris Kise.

Kise argued that the inaccuracies in Trump's statement of financial condition can cut both ways: Even if some properties were overvalued, other properties like Doral were significantly undervalued and balanced out the statement, according to Kise.

"It is highly, extraordinarily relevant if there are assets that are undervalued substantially on those same statements," Kise said. "They can't look at this one-sided."

State attorney Andrew Amer fiercely rebutted that argument, telling Engoron he should not take the defense's position that the inconsistencies "come out in the wash."

That argument appeared to convince Engoron, who said that overvaluations would not "insulate" a false valuation. He promised to sustain any objection that related to the value of Doral -- an approach Kise described as "lunacy."

"The reader of the financial statement has the right to know whether each particular number was accurate," Engoron said. "They are looking for accuracy."
