Making a political plus of math error, Star Tribune, 12 Apr 06
DFLer Rebecca Otto is accusing Auditor Pat Anderson, a Republican, of sloppy work. In a column reporting the percentage changes in unreserved fund balances from 2003 to 2004, instead of dividing the difference by the 2003 figure, the auditor's office divided it by the 2004 figure. Deputy Auditor Tony Sutton said "The researcher who worked on that report just made a mistake in the formula in the spreadsheet. He feels bad about it."

The Register (UK) OGC spreadsheet madness 10 Mar 06
The Office of Government Commerce is blaming a spreadsheet error for a foul-up over accrediting suppliers for its new Catalist procurement programme. In a letter to suppliers, they confessed "Unfortunately, [we are] not, as we had hoped, in a position to accept your tender at this time. This is because an error in the original evaluation spreadsheet has been identified, necessitating rescoring of all tenders for this project... this error has now been corrected and this has caused a small number of changes to the original award decision."

HUD alleges overpayment for Section 8 
Columbia Tribune, February 22, 2006. A government audit says the Columbia Housing Authority has to pay $216,352 to cover expenses incurred when the authority gave some Section 8 tenants too much room and some landlords too much rent. They admitted to $118,387, the amount that resulted from a spreadsheet data-entry error that overpaid landlords.

TORONTO (CP) - Sun Life Financial Inc.'s (TSX:SLF - news) fourth-quarter profit increased more than nine per cent to $478 million, a day early than scheduled after "human error" left the company vulnerable to a possible leak. The problem centred around the company's quarterly statistical supplement, which is regularly provided to the analyst community in advance of earnings - but with the latest quarterly results blanked out. In doing so, the spreadsheet is converted into a document file. However, the censored information could be recovered by using Acrobat software, explained spokesman Tom Reid.

An audit report of San Bernardino Valley's bus agency Omnitrans found "long-term weaknesses" in some areas, including a lack of internal controls in purchasing "that increases the risk of potential fraud and misuse." The financial software that cost the agency more than $200,000 remains unused, and maintenance contracts for the software that can't be canceled remain in effect. The agency, which has an operating budget of $63 million, currently does most of its bookkeeping on Microsoft Excel.

Budget discrepancies attributed to computer error Jan 6, 2006
The Nevada city budget spreadsheet apparently worked correctly until sometime in late December 2005 when, city finance director Ron Chandler says, it developed a problem, causing the 2006 budget to show a $5 million deficit in the water and sewer fund. Chandler said that it took him most of the day Wednesday to fix the problem. While he was working on it he found some other errors in the spreadsheet that needed to be corrected. "Once it's a PDF it can't change," Chandler said.

Dud spreadsheet threatens case By Leonie Wood November 10, 2005 A MULTIMILLION-DOLLAR petrol price-fixing case being led by the Australian Competition and Consumer Commission in the Federal Court has been seriously jeopardised by admissions from it that one of its investigators made up some of the evidence. The ACCC is relying on a huge spreadsheet which lists petrol prices and times of price changes to corroborate oral evidence from witnesses, including some of the petrol station operators, that Geelong fuel retailers worked together to push up prices in 1999 and 2000. ACCC's chief investigator Jane Edwards admitted that "at the risk of fingering one of my staff members", one of the investigators had cut and pasted slabs of data into the spreadsheet. Ms Edwards at the time told the court that the investigator was "very enthusiastic and he thought he had skills that we weren't aware of that might be of use", so he hurdled the problem that the ACCC lacked information about price movements on some dates by duplicating data from other dates.

Kodak restates, adds $9 million to loss By Jim Jelter, MarketWatch Nov. 9, 2005

SAN FRANCISCO (MarketWatch) - The hefty $11 million severance error was traced to a faulty spreadsheet. Kodak spokesman Gerard Meuchner said "There were too many zeros added to the employee's accrued severance. But it was an accrual. There was never a payment," he said. Robert Brust, Kodak's chief financial officer, called it  "an internal control deficiency that constitutes a material weakness that impacted the accounting for restructurings."

Westpac was forced to halt trading on its shares and deliver its annual profit briefing a day early after it accidentally sent its results by email to research analysts. Details of the $2.818 billion record profit result for the 12 months to September 30, were embedded in a template of last year's results and were accessible with minor manipulation of the spreadsheet. (Some reports indicated an employee had thought that a black cell background fill would hide black text.) Mr Chronican said "It is not just one error, it is a compounding of two or three errors...

"Some aspiring police officers who took a government exam said they were told they passed a big test, but found out later that they had actually failed. A national company called AON administered the test and told the board someone incorrectly sorted the results on a spreadsheet, so the names and scores were mismatched", NBC 13's Kathy Times reported.

Natural gas consumers sue Dominion Transmission over clerical error, 17 June 2005
A Federal Energy Regulatory Commission investigation found that the subsidiary of Richmond, Va.-based Dominion Resources Inc. submitted the wrong week's gas storage figures in November, leading to an artificial inflation of natural gas prices. The lawsuit estimates that consumer prices were hiked by between $200 million and $1 billion. "The investigation concluded that it was not deliberate, but when I hear the words clerical error, I think of negligence," plaintiff's attorney W. Coleman Allen Jr., of Richmond, Va., said Friday. "Consumers were harmed the same as if it was intentional." One explanation for the error was that the company had used the same computer file name for each week's storage balance spreadsheet report, making it easy for the wrong one to be sent.

The Center for Regional Strategies recently confirmed that a researcher's errant cut-and-paste from a spreadsheet caused one measure of the region's level of educational attainment to appear a lot worse than it is. The Center for Regional Strategies, a self-described "think-and-do tank" housed at Virginia Tech, reported that a dismal 11 percent of the region's population older than 25 had bachelor's degrees or higher. That number should have been 20 percent. Stuart Mease, a spokesman for the Center for Regional Strategies, said "It was just a simple cut-and-paste error," he said. "I don't know how it happened, but it did. We apologize for our mistake and want to correct it."

RedEnvelope Cuts Outlook, Shares Fall,  CFO Eric Wong Resigns Amid Budget Errors
NEW YORK (AP) -- Shares of RedEnvelope Inc. tumbled more than 25 percent Tuesday after the online retailer of specialty gifts drastically reduced its fourth-quarter outlook and said its chief financial officer will resign in April. Stanford Group analyst Rebecca Jones Kujawa said in an interview. "...they were underestimating the cost of goods sold....it is likely CFO Eric Wong is being pushed out because of this error, which could demonstrate a material weakness in controls over financial reporting, an issue that usually leads to a lengthy review of accounting practices." RedEnvelope spokeswoman Jordan Goldstein said the budgeting error was simply due to a number mis-recorded in one cell of a spreadsheet that then threw off the cost forecast and was unrelated to the CFO change.

National Leader Don Brash used a wildly inflated number when he told the Ratana gathering on Monday that nearly half of all Maori children were dependent on a benefit. The figure - which strongly featured in news reports of the high-profile Maori gathering - was the result of a calculating error by the Parliamentary Library. The estimate should have been 30 per cent, said parliamentary researcher David Williams, who owned up to the Herald about making the mistake. He has apologised to Dr Brash.

Excel spreadsheets in Budgeting; Accountingweb 5-Mar-2001
School governor Peter Wolstenholme explained how his school faced a 30,000 shortfall because values in a budget spreadsheet had not been added up correctly. With help from several of AccountingWEB's Excel gurus, he managed to identify the underlying problem was due to budget figures being entered as right-aligned text values rather than as numbers. The text figures were not included within the =Sum calculation and rippled through to the school's budget submission. Wolstenholme acknowleded that he often gets text values turning up in Excel spreadsheets when he extracts data from his accounting system using the ODBC mechanism.

GAO report number GAO-04-754T entitled 'National Aeronautics and Space Administration: Significant Actions Needed to Address Long-standing Financial Management Problems'  "NASA's fiscal year 1999 SBR was misstated by a reported $644 million due, in part, to a misinterpretation of guidance and errors in NASA's ad hoc process for generating budgetary information. As a result, the NASA locations used various methods to extract the data for this line item from their separate systems and entered the data on spreadsheets, which were then compiled by NASA headquarters. ... NASA officials have indicated that undetected errors in this spreadsheet process- in addition to the inclusion of the erroneous category of transactions-were also responsible for a portion of the SBR misstatement. According to NASA officials, they have strengthened internal controls over this process for fiscal year 2000. Arthur Andersen did not detect the error in NASA's SBR during its audit of the fiscal year 1999 financial statements. Evidence in Arthur Andersen's working papers relating to understanding and testing internal controls and validating underlying data for key financial statement balances was not adequate to support Arthur Andersen's unqualified audit opinion' on the SBR and Statement of Financing for fiscal year 1999. ... The other errors of approximately $32 million related to errors in the spreadsheet data may have had an impact on the P&F Schedules."

When is a mistake not a mistake?, Nov 1, 2004
In a loan dispute, a spreadsheet prepared by a claimant sought to calculate the total interest due under the loan. A mistake was not discovered during the negotiations and, in due course, the parties agreed a settlement figure of 55,000 on the mutually mistaken assumption that this equated to a rate of interest of about 45%. In truth, 55,000 equated to an interest rate of approximately 33%. The court held the mistake was not the fault of either the parties and, furthermore, there was no warranty as to the spreadsheet. They were commercial parties and had agreed on a fixed sum. They were both (mutually) mistaken and there was no injustice. "

Business Council: Economic Survey Wrong, Tue Oct 12, 2004
"NEW YORK (Reuters) - The Business Council, a group of 125 U.S. CEOs, last week said 70 percent of its members expected flat to 2 percent growth in the U.S. economy next year -- painting a much more bearish outlook than major economists. But on Tuesday, the group said it had gotten the survey wrong and its members had actually projected moderate to solid economic growth in 2005, from 2.1 percent to 4.5 percent, and were 'guardedly optimistic' about the economy's prospects. 'It was a computational error. The spreadsheet shifted so the wrong numbers appeared in the wrong columns,' Cassidy said. 'It was just one column on the spreadsheet.' He said the error, which was caught on Friday afternoon, has never happened before in the survey's history."

I was entering grades in an Excel spreadsheet and realized that although in my notes I had a mix of A's and A-'s, the spreadsheet had changed all the A grades to A-'s. Why? I was entering grades looking at my notes and not the screen. So I typed A- followed by ENTER, then A at which point Excel suggested A- as a possible input. Without looking I pressed ENTER, thus entering A- instead of A. This only works if the longer input precedes the shorter in the original list (i.e., the list you are typing from), since if there is ambiguity about the suggestion, Excel shuts up.

The problem was default date format conversions and floating-point format conversions in Excel.

A well-known Grand Rapids investment manager's alleged mishandling of stock orders has led to $475,000 in fines by the New York Stock Exchange and censures for him and two other employees involved in the orders.
The stock exchange said Cusack, 47, bought large blocks of Foremost stock in September and October of 1999, but didn't properly document which of his clients would have the stock placed in their accounts. The lack of documentation raised the possibility that he could wait to decide how to distribute the shares until he knew how the shares performed that day -- a violation of NYSE rules and Securities and Exchange Commission laws.
Cusack told the stock exchange he had a spreadsheet that spelled out how the stock would be distributed when the orders were placed, but the spreadsheet was thrown away after the transactions and other documentation were completed.

Education Networks of America (ENA) operates the Internet network connecting schools across Tennessee. ENA twice won multimillion-dollar state contracts with bids that appeared higher than others. Jacqueline Shrago, who was the Education Department's project manager, said the ISIS 2000 bid appeared cheaper until costs for all three and a half years were computed. Looking more closely, it appeared that ISIS had made an error on a spreadsheet and that the bid actually was higher than ENA's, she said. 'We asked questions in the protest period, and they would not give an answer,' Shrago said.

Watchdog Calls for Further Investigation of MCI
The August 2003 Department of Defense IG report states, "... many of the invoice amounts listed on the MCIWorldCom spreadsheet were inaccurate. Specifically, 467 invoices on the MCIWorldCom spreadsheet differed from the hard copy invoices by $2.1 million. Last month, The New York Post reported a former MCI employee's claim about over-billing at the State Department: "It was wrong and I regret it. We were over-billing the government $20,000 a month on one circuit. [The order to overcharge] came down from a vice president and through three layers of management."

The city has a three-step process for elections: The first part was getting the voting books from the county and checking them. After that step was completed, the names were added to an Excel spreadsheet in the city's computer. "The information from Excel had to be entered into another database, COBOL. Apparently what happened is that when the rolls were printed, all the information did not get transferred," Alexander said. "Entire neighborhoods were left off of the voter rolls."

020) $12M Error inflates school impact fees in Florida

September 12, 2003 Orlando Sentinel
Assistant County Manager Cindy Hall, in a memo to commissioners on Thursday, wrote that the April 22 study by Henderson Young & Co. duplicated the cost of building a new elementary school. The extra $12 million cost was corrected on a spreadsheet in the study, but it wasn't later adjusted on the total cost of school projects for the next five years. Jim Drake, director of finance for Lake County Public Schools, said: "It was basically a simple spreadsheet error. But obviously it's going to have an impact on building new facilities." County Commissioner Jennifer Hill said the consultant was given the final numbers for its study from the School Board only a few months before the study's completion, "It was rush, rush, rush," she said. Hill called the mistake "a simple mathematical error".

June 03, 2003 TORONTO (Reuters) - TransAlta Corp. said on Tuesday it will take a $24 million charge to earnings after a bidding snafu landed it more U.S. power transmission hedging contracts than it bargained for, at higher prices than it wanted to pay.
[...] the company's computer spreadsheet contained mismatched bids for the contracts, it said. "It was literally a cut-and-paste error in an Excel spreadsheet that we did not detect when we did our final sorting and ranking bids prior to submission," TransAlta chief executive Steve Snyder said in a conference call. "I am clearly disappointed over this event. The important thing is to learn from it, which we've done."
As New York ISO rules did not allow for a reversal of the bids, the contracts went ahead.

017) Economic Testimony - The Good, the Bad, and the Ugly

Article: http://www.rrc-inc.com/articles_economic_testimony.php (undated)

"There are times in which the economic expert is either unprepared or led into difficult positions. Likewise, there are times in which the cross examination opens the door for further damaging economic testimony. Over the years, we have compiled a list of some of the goofs and some of the successes among economic experts we have observed. ".

What spreadsheet?

During trial the plaintiff's attorney during cross examination focused upon the computer spreadsheet used by the defense's economic expert to allegedly prove that there were zero economic damages. The expert had relied heavily upon research assistants to construct the spreadsheet, but under the expert's supervision. Unfortunately, the expert had not carefully examined the calculations and was not aware of several calculation errors. The spreadsheet was blown up as a trial exhibit, along with an alternate spreadsheet with corrected figures. The expert's testimony at trial was inconsistent with the corrected spreadsheet. The expert was forced to acknowledge to the court the calculation error, and tried to explain it was not a serious one. Yet it was too late. The jury lost confidence in the testimony. The jury awarded the plaintiff more than $12 million in damages.

Did you copy all the way down?

A plaintiff's economic expert was claiming that damages were to accrue over an extended period of time due to a permanently damaged reputation. Due to an incorrect use of a copy command in the spreadsheet, the lost profits after the tenth year of the projection became discontinuous, abruptly decreasing in one month, then following a smooth trend upward though the remainder of the time horizon.  The economist had revised the spreadsheet, but failed to copy the revision down all cells, stopping after ten years. The remainder of the projection used the unrevised formula which abruptly took the profits into the negative regions. Since the profits were projected for a surgeon, it made little economic sense that a surgeon would continue practicing for several years with a negative income.

Upon questioning in the deposition, the expert could not quickly figure out the reason for the questions and admitted that, if the projection showed it, it was quite possible for profits to be negative for short periods of time. Problems and inconsistencies could have been detected by the expert by simply graphing the result. However, the expert chose not to admit the possibility of a mistake in a deposition and provided damaging testimony instead.

V. Krishnaraj from THE HINDU, Jul 10, 2002

"Users often fail to realise the implication of Spreadsheets they develop. There is no third party independently testing whether these sheets work correctly. In course of time, they get used unquestioningly with nobody cross checking the validity of calculations. We've never come across a company validating software embedded in Spreadsheets. "

"To illustrate, here's a case we encountered with a corporate that was showing its procedures to be supported by well-documented Spreadsheets. Taking a deeper look at their sheets, we were surprised to find them using a wrong function for IRR calculation (Tip: There are 2 Excel IRR functions IRR() and XIRR(). XIRR() handles non-periodic cashflows while IRR() can handle only periodic cash flows). Over the last couple of years, the top management has been looking at reports with this wrong computation!! We can't imagine what decisions were made using these numbers. "

CSLP explained that it had made an error on the spreadsheet CSLP used to calculate the beginning balance of the Operating Fund. A formula in the spreadsheet picked-up the date, 12/02/98, and interpreted it as a dollar amount, resulting in an error of $36,131. As a result, the beginning balance of the Federal Fund was understated by $36,131. We calculated that CSLP owed the Federal Fund an additional $8,884 in imputed interest on this amount calculated through March 31, 2002. Not correcting such an error would be inconsistent with sound business practices, as required by 34 CFR (a)(11)(iii)(B)."

The error showed up during that process many months later.

It was as simple and unbelievable as that, but that is what happened. As the county engineer has reminded me, it happened in two tenders and it was not seen by us in the checking process. "

"[Discussion] With strict liability, factors of intent, good faith, willfulness or fault are not relevant to a finding of liability for violations. Therefore, Respondent's arguments that it intended to comply, did not know of the violations, and made an innocent mistake are not defenses to liability.
