After concessions, ¹ the issue for decision is whether petitioner2003 Tax Ct. Memo LEXIS 43">*44 is entitled to deductions and/or losses in amounts greater than those allowed by respondent for the years in issue.

           FINDINGS OF FACT

Some of the facts have been stipulated and are so found. The deemed admissions, the stipulation of facts, and the attached exhibits are incorporated herein by this reference. At the time he filed the petition, petitioner resided in Pound Ridge, 2003 Tax Ct. Memo LEXIS 43">*45 New York.

During the years in issue, petitioner was a senior executive of a merchant bank in Australia, president of a New York investment company, and an underwriter with Lloyd's of London (Lloyd's).

Stephen Swain and Steven Conway were shareholders in a small investment bank named S.J. Conway & Company (SJC). During 1987 and 1988, events occurred that made Mr. Swain want to "get out of" SJC. In February 1988, Mr. Swain and Mr. Conway reached an agreement for Mr. Conway to buy out Mr. Swain's shares of SJC (agreement). Mr. Conway agreed to make a staged payout to Mr. Swain.

Mr. Conway violated the agreement by failing to make payments. This caused an acceleration of the payout. Mr. Swain "pressed" Mr. Conway for the money he was owed. On September 9, 1988, Mr. Conway paid Mr. Swain in full. Mr. Swain did not see any documentation regarding where the money Mr. Conway paid him came from.

                OPINION

Deductions are a matter of legislative grace, and petitioner has the burden of showing that he is entitled to any deductions. ²Rule 142(a); New Colonial Ice Co. v. Helvering, 292 U.S. 435">292 U.S. 435, 292 U.S. 435">440, 78 L. Ed. 1348">78 L. Ed. 1348, 54 S. Ct. 788">54 S. Ct. 788 (1934).

2003 Tax Ct. Memo LEXIS 43">*46 Alleged Investments

Petitioner claims:

     (1) He was approached by Mr. Conway to make an

   investment in SJC; in September 1988 he invested

   approximately $ 125,000 in SJC; and in 1989 SJC filed

   for bankruptcy;

     (2) he suffered losses as a Lloyd's underwriter;

     (3) in 1991 he invested $ 25,000 in a company

   called Marisco International Trading (Marisco) in which

   Al Marisco was the principal; and Marisco "wound up" in

   1992 (but petitioner testified that he was not able to

   verify this);

     (4) in 1984 he invested $ 5,000 in a company called

   C Films; C Films "wound up" years later; and he lost

   his entire investment in C Films; and

     (5) he advanced approximately $ 85,000 to a company

   his wife founded and ran called Stamp, Stamp, Stamp (SSS); SSS

   closed in 1993; and he lost $ 50,000 when SSS closed.

We review the economic realities of transactions between family members -- i.e., the SSS transactions -- with heightened scrutiny. Estate of Reynolds v. Commissioner, 55 T.C. 172">55 T.C. 172, 55 T.C. 172">201 (1970). Petitioner2003 Tax Ct. Memo LEXIS 43">*47 relies on his own testimony to substantiate his losses from SJC, Lloyd's, Marisco, C Films, and SSS. The Court is not required to accept petitioner's unsubstantiated testimony. Wood v. Commissioner, 338 F.2d 602">338 F.2d 602, 338 F.2d 602">605 (9th Cir. 1964), affg. 41 T.C. 593">41 T.C. 593 (1964).

Petitioner did not present any evidence regarding when C Films supposedly wound up or when he "lost" this investment.

Petitioner submitted 6 pages of a 13-page fax containing a settlement offer and "Finality Statement -- August 1996" regarding Lloyd's. The document does not establish that petitioner incurred or sustained losses regarding Lloyd's during the years in issue.

Mr. Swain's testimony does not support petitioner's assertion that he invested money in, or suffered a loss related to, SJC. Mr. Swain had no personal knowledge regarding whether (1) the money he received from Mr. Conway originally came from petitioner, (2) the money was given to Mr. Conway or SJC, or (3) the money was an investment or a loan. Mr. Swain did not see any documentation regarding where the money Mr. Conway paid him came from. Furthermore, Mr. Swain did not testify regarding whether SJC went bankrupt.

Additionally, we2003 Tax Ct. Memo LEXIS 43">*48 note that Mr. Conway and Mr. Marisco were not called as witnesses. We infer that their testimony would not have been favorable to petitioner. Wichita Terminal Elevator Co. v. Commissioner, 6 T.C. 1158">6 T.C. 1158, 6 T.C. 1158">1165 (1946), affd. 162 F.2d 513">162 F.2d 513 (10th Cir. 1947).

We found petitioner's testimony to be general, vague, conclusory, and/or questionable in certain material respects. Under the circumstances presented here, we are not required to, and generally do not, rely on petitioner's testimony to sustain his burden of establishing error in respondent's determinations. Lerch v. Commissioner, 877 F.2d 624">877 F.2d 624, 877 F.2d 624">631-632 (7th Cir. 1989), affg. T.C. Memo. 1987-295; Geiger v. Commissioner, 440 F.2d 688">440 F.2d 688, 440 F.2d 688">689-690 (9th Cir. 1971), affg. per curiam T.C. Memo. 1969-159; Tokarski v. Commissioner, 87 T.C. 74">87 T.C. 74, 87 T.C. 74">77 (1986).

We hold that petitioner is not entitled to claim loss deductions in any amount for any of the years in issue relating to SJC, Lloyd's, Marisco, C Films, and SSS.

Remaining Issues

Petitioner did not present any evidence at trial regarding any of the remaining issues he raised in his petition. Therefore, we2003 Tax Ct. Memo LEXIS 43">*49 conclude that petitioner has abandoned these issues. Petzoldt v. Commissioner, 92 T.C. 661">92 T.C. 661, 92 T.C. 661">683 (1989); Money v. Commissioner, 89 T.C. 46">89 T.C. 46, 89 T.C. 46">48 (1987).

At the conclusion of the trial, the Court advised petitioner that once the trial was finished the record would be closed and petitioner would not be able to submit additional evidence. Petitioner attached to his posttrial briefs documents he argues support the deductions and losses he claims he is entitled to for the years in issue. Evidence must be submitted at trial; documents attached to briefs and statements therein are not evidence. Rule 143(b); Lombard v. Commissioner, T.C. Memo. 1994-154 n.3, affd. without published opinion 57 F.3d 1066">57 F.3d 1066 (4th Cir. 1995); Wicker v. Commissioner, T.C. Memo. 1993-431 n. 15, affd. without published opinion 50 F.3d 12">50 F.3d 12 (8th Cir. 1995). Accordingly, we disregard these documents in reaching our decision.

We conclude that petitioner is not entitled to deductions or losses in amounts greater than those allowed by respondent for the years in issue. To reflect the foregoing,

Decision will be entered under Rule 155.
