[*2] I. GSP Precision, Inc.

GSP Precision, Inc. (GSP), was an aerospace manufacturing company incorporated under California law in 1983 by George J. Gottardi and Juan Pablo Prezioso, petitioner Walter Prezioso’s father. George 1 and Juan Pablo each held a 50% interest in GSP and were members of its board of directors (Board). George’s wife, Marta Gottardi, and Juan Pablo’s wife, Magdalena Prezioso, also were Board members.

II. Petitioners’ involvement in GSP

Walter graduated with a bachelor’s degree in computer information systems. Shortly after, Walter joined GSP in 1992. Walter’s compensation was reported on Form 1099 2 issued to WDP Computer Programming, an entity Walter formed in 1995.

In 1997 Walter acquired a 25% interest in GSP from his father, paying $25,000 immediately and then $1,500 each month for ten years. Following this purchase, George retained a 50% interest, Juan Pablo held 25%, and Walter held 25%. At that same time Walter was put on GSP’s payroll as an employee.

Walter gradually took over the day-to-day management of GSP.

On February 27, 2001, the Board adopted a resolution that Walter’s was the only signature required for any checks issued by GSP. At another meeting, on June 6, 2002, the Board adopted a resolution that George and Juan Pablo would effectively retire from GSP’s day-to-day operations while retaining their shares and status as Board members. It further stated that future employment decisions would be Walter’s alone, except for the employment of family members, which required unanimous Board approval.

Around that time, GSP’s financials began to worsen. George and Juan Pablo made some loans to GSP, but their desire to make additional loans dissipated. On February 28, 2005, the Board adopted a resolution approving a $50,000 loan from Walter to GSP. Walter also made subsequent loans to GSP. Eventually Walter turned GSP’s fortunes

ownership, we will refer to members of the Prezioso and the Gottardi families by their first names.

was used.

[*3] around by diversifying its customer base and implementing new technology. Walter became GSP’s chief executive officer in 2007.

III. GSP’s payment of Walter’s personal expenses

Beginning in 2007 GSP began paying certain of Walter’s personal expenses. The first Board minutes addressing GSP’s payment of Walter’s personal expenses, dated December 22, 2009, stated that GSP will “continue to pay personal leased vehicle, vehicle insurance, gas, family medical insurance, Sentry life insurance[,] and credit card expenses for lunch, dinner, customer expenses[,] or company expenses.”

GSP paid more of Walter’s personal expenses than those explicitly listed in the minutes. For example, GSP paid for personal credit cards, home renovations, a home-equity line of credit, landscaping services, tennis court and pool contractors, and audio/visual equipment. GSP also paid Walter’s boat and recreational vehicle loans and leased vehicles on Walter’s behalf. For the years in issue GSP issued over 400 checks for Walter’s personal expenses. During all the years in issue except 2012, the amounts GSP paid for Walter’s personal expenses exceeded the losses reported on its Forms 1120, U.S. Corporation Income Tax Return.

Walter remained on GSP’s payroll for his regular salary; GSP paid certain of his personal expenses in lieu of the types of compensation paid to George and Juan Pablo and reported on Forms 1099 issued to them. GSP’s payment of Walter’s personal expenses was not reported on any Forms W–2, Wage and Tax Statement, or Forms 1099–MISC, Miscellaneous Income, issued to Walter; thus, for the years in issue, these benefits were not subject to payroll taxes or federal income tax reporting. Walter understood that they were compensation, however. On a credit application for a Ferrari lease, Walter listed his income as “Verifiable $52,950 W-2” and “Actual $275,000.”

IV. GSP’s accounting practices

Walter concealed GSP’s payment of many of these personal expenses through bookkeeping practices. John Caven3 of Caven & Associates served as GSP’s outside accountant and tax return preparer. But GSP had no accountant on staff; thus, Walter was primarily responsible for entering checks and invoices into GSP’s bookkeeping

3 After Mr. Caven died in 2012, GSP hired another accountant; however,

nothing in the record indicates that GSP’s bookkeeping processes changed substantially.

[*4] software. This required two relevant steps: entering the payee’s identity and assigning an expense code. The software then could be used to produce a chart of accounts that showed the date, the payee, the amount, and the expense code.

As discussed below, Walter’s entry of his personal expenses into GSP’s books resulted in two sets of charts of accounts for GSP: an internal set provided to GSP shareholders for periodic review (Internal Charts) and an external set provided to Mr. Caven for accounting and tax purposes (Accountant Charts). Each month Walter would send the Accountant Charts, check register, and bank statements to Mr. Caven. Mr. Caven did not receive, and was not aware of, the Internal Charts.

A. Payee’s identity

In the Internal Charts Walter commonly disguised the payment of his personal expenses by entering a different payee, usually an existing vendor for GSP. For example, two checks dated February 2, 2011, were made payable to “Chase Card” for $4,093.80 and $3,167.10, respectively. The Internal Charts listed the payees as Cowan Precision Grinding and Quality Heat Treating, Inc., respectively. Other sets of entries listed payees such as Harvey Titanium, Titanium Industries, and Service Steel instead of Chase, the actual payee.

Walter changed the payee’s name for his personal expenses even when GSP paid business expenses to the same vendor. For example, GSP issued two checks to Washington Mutual in October 2007. One check issued for GSP’s business expenses was recorded in the Internal Charts as payable to Washington Mutual. The other, a personal expense for Walter, was recorded as payable to “A.M. Castle & Co.” On other occasions, direct payments from GSP to Walter and Juan Pablo were omitted entirely from the Internal Charts.

When generating the Accountant Charts at the end of each month, Walter’s standard practice was to change the payee names on the Internal Charts to the correct payee names. He failed to do so for at least three expenses paid in December 2011, thereby leaving the incorrect payee names from the Internal Charts on the Accountant Charts. After generating the Accountant Charts, Walter would change the payee names back to incorrect ones.
