The X Bank is a commercial bank which has a calendar year as its taxable year. X adopted the reserve method of accounting for bad debts in 1950. On December 31, 1969, X has $1,000,000 of outstanding eligible loans and a balance of $13,000 in its reserve for losses on loans. The base year is 1969 and, consequently, X has a reserve deficiency of $5,000 ((1.8% × $1,000,000) − $13,000).
(a) During 1970, X has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1970, X has $1,050,000 of outstanding eligible loans. The maximum reasonable addition under the percentage method is $2,900 which consists of $1,000 of reserve deficiency ( 1/5 × $5,000), the $1,000 in net bad debts charged to the reserve for losses on loans, and $900 attributable to the increase in the balance of eligible loans (1.8% × ($1,050,000 − $1,000,000)). Assuming that X makes an addition to the reserve for losses on loans of $2,900 for the year, the balance of the reserve as of December 31, 1970 is $14,900 ($13,000 − $1,000 + $2,900).
(b) During 1971, X has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1971, X has $800,000 of outstanding eligible loans. The allowable percentage of eligible loans is $14,400 (1.8% × $800,000). The maximum reasonable addition under the percentage method is $500 which is a portion of one-fifth of the reserve deficiency. Assuming that X makes an addition to the reserve for losses on loans of $500 for the year, the balance of the reserve as of December 31, 1971, is $14,400 ($14,900 − $1,000 + $500).
(c) During 1972, X has net bad debts of $600 charged to the reserve for losses on loans. On December 31, 1972, X has $850,000 of outstanding eligible loans. The allowable percentage of eligible loans is $15,300 (1.8% × $850,000). The maximum reasonable addition under the percentage method is $1,500 which consists of $1,000 of reserve deficiency ( 1/5 × $5,000) and $500 of the net bad debts charged to the reserve for losses on loans in 1971. Even though the full addition with respect to the reserve deficiency in 1971 was not made, the amount of the addition that can be made in 1972 with respect to the reserve deficiency is limited to one-fifth of such deficiency. Assuming that X makes an addition to the reserve for losses on loans of $1,500 for the year, the balance of the reserve as of December 31, 1972, is $15,300 ($14,400 − $600 + $1,500).
(d) During 1973, X did not have any net bad debts charged to the reserve for losses on loans. On December 31, 1973, X has $1,000,000 of outstanding eligible loans. The allowable percentage of eligible loans is $18,000 (1.8% × $1,000,000). The maximum reasonable addition under the percentage method is $2,100 which consists of $1,000 of reserve deficiency ( 1/5 × $5,000), $500 of net bad debts charged to the reserve for losses in 1971, and $600 of net bad debts charged to the reserve in 1972. Although outstanding eligible loans increased from $850,000 in 1972 to $1,000,000 in 1973, no addition is permitted with respect to the increase because the amount of eligible loans outstanding at the close of 1973 ($1,000,000) does not exceed the sum of the amount of such loans at the close of the base year ($1,000,000) and the amount of previous increases in such loans for which an addition was made in taxable years ending after the close of the base year ($50,000 loan increase in 1970). Assuming that X makes an addition to the reserve for losses on loans of $2,100, the balance of the reserve as of December 31, 1973, is $17,400 ($15,300 + $2,100).
The M Bank is a commercial bank which has a calendar year as its taxable year. M adopted the reserve method of accounting for bad debts in 1950. On December 31, 1969, M has $1,000,000 of outstanding eligible loans and a balance of $20,000 in its reserve for losses on loans.
(a) During 1970, M has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1970, M has $1,100,000 of outstanding eligible loans. The allowable percentage of eligible loans is $19,800 (1.8% × $1,100,000). The maximum reasonable addition under the percentage method is $1,000 which is the amount sufficient to increase the balance of the reserve as of the close of the taxable year to the balance of the reserve as of the close of the 1969 base year ($20,000). Assuming that M makes an addition to the reserve for losses on loans of $1,000 for the year, the balance of the reserve as of December 31, 1970, is $20,000 ($20,000 − $1,000 + $1,000).
(b) During 1971, M has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1971, M has $1,300,000 of outstanding eligible loans. The allowable percentage of eligible loans is $23,400 (1.8% × $1,300,000). The maximum reasonable addition under the percentage method is $4,400 which is the amount sufficient to increase the balance of the reserve to the allowable percentage of eligible loans outstanding at the close of the taxable year. Assuming that M makes an addition to the reserve for losses on loans of $4,400 for the year, the balance of the reserve as of December 31, 1971, is $23,400 ($20,000 − $1,000 + $4,400).
(c) During 1972, M has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1972, M has $1,200,000 of outstanding eligible loans. The allowable percentage of eligible loans is $21,600 (1.8% × $1,200,000). No reasonable addition may be made under the percentage method because the reserve for losses on loans ($22,400, i.e., $23,400−$1,000) is greater than the allowable percentage of eligible loans outstanding at the close of the taxable year ($21,600) and the balance of the reserve as of the close of the base year ($20,000). Assuming that no amount is added under the experience method provided by paragraph (c) of this section, the balance of the reserve for losses on loans as of December 31, 1972, is $22,400 ($23,400−$1,000).
(d) During 1973, M has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1973, M has $1,200,000 of outstanding eligible loans. The allowable percentage of eligible loans is $21,600 (1.8% × $1,200,000). The maximum reasonable addition under the percentage method is $200 which is the amount sufficient to increase the reserve for losses on loans to the allowable percentage of eligible loans outstanding at the close of the taxable year. Assuming that M makes an addition to the reserve for losses on loans of $200 for the year, the balance of the reserve as of December 31, 1973, is $21,600 ($22,400−$1,000 + $200).
The N Bank is a commercial bank which has a calendar year as its taxable year. N adopted the reserve method of accounting for bad debts in 1950. On December 31, 1969, N has $1,000,000 of outstanding eligible loans and a balance of $20,000 in its reserve for losses on loans.
(a) During 1970, N has net bad debts of $3,000 charged to the reserve for losses on loans. On December 31, 1970, N has $900,000 of outstanding eligible loans. The maximum reasonable addition under the percentage method is $1,000, which is the amount necessary to increase the balance of the reserve to the amount ($18,000) which bears the same ratio to eligible loans outstanding at the close of the taxable year ($900,000) as the balance of the reserve as of the close of the base year ($20,000) bears to the amount of the eligible loans outstanding at the close of the base year ($1,000,000). Assuming that N makes an addition to the reserve for losses on loans of $1,000 for the year, the balance of the reserve as of December 31, 1970, is $18,000 ($20,000−$3,000 + $1,000).
(b) During 1971, N has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1971, N has $1,100,000 of outstanding eligible loans. The maximum reasonable addition under the percentage method, determined under subdivision (iii) of this subparagraph, is $3,000 which is the amount necessary to increase the balance of the reserve to the greater of the allowable percentage of eligible loans outstanding at the close of the taxable year ($19,800) or the balance of the reserve at the close of the base year ($20,000). Assuming that N makes an addition to the reserve for losses on loans of $3,000 for the year, the balance of the reserve as of December 31, 1971 is $20,000 ($18,000−$1,000 + $3,000).
The application of the rules provided by this subparagraph may be illustrated by the following example:
The Y Bank begins business as a commercial bank on July 1, 1974. Y adopts the calendar year as its taxable year and the reserve method of accounting for bad debts.
(a) During 1974, Y has net bad debts of $1,000. On December 31, 1974, Y has $1,000,000 of outstanding eligible loans. Under subparagraph (1)(ii)(B) of this paragraph, because Y is a newly-organized financial institution, there is no reserve deficiency. Except for the limitations of this subparagraph, the maximum reasonable addition under subparagraph (1)(ii)(A) of this paragraph would be the amount of net bad debts charged to the reserve for losses ($1,000) plus the allowable percentage of outstanding eligible loans at the close of the taxable year $18,000 (1.8% × $1,000,000). However, because of the limitations of this subparagraph, the maximum reasonable addition to the reserve for losses on loans under the percentage method is an amount sufficient to increase the balance of the reserve for losses on loans to $6,000 which is 0.6 percent of the eligible loans outstanding at the close of the taxable year. Assuming that Y makes an addition to the reserve for losses on loans of $7,000 for the year, the balance of the reserve as of December 31, 1974, is $6,000 ($7,000−$1,000). The $7,000 consists of the $1,000 in net bad debts and $6,000 attributable to the increase in eligible loans outstanding.
(b) During 1975, Y has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1975, Y has $1,000,000 of outstanding eligible loans. Except for the limitations of this subparagraph, the maximum reasonable addition under subparagraph (1)(ii)(A) of this paragraph would be the amount of net bad debts charged to the reserve for losses ($1,000) plus an amount attributable to the increase in the amount of eligible loans outstanding with respect to which no reasonable addition was allowed in 1974 ($12,000, i.e., $18,000−$6,000). However, because of the limitations of this paragraph, the maximum reasonable addition to the reserve for losses on loans under the percentage method is $6,000 which is an amount equal to 0.6 percent of the eligible loans outstanding at the close of the taxable year. This amount consists of net bad debts of $1,000 and $5,000 attributable to a portion of the increase in eligible loans in 1974 with respect to which no reasonable addition was allowable for 1974. Assuming that Y makes an addition to the reserve for losses on loans of $6,000 for the year, the balance of the reserve as of December 31, 1975, is $11,000 ($6,000−$1,000 + $6,000).
(c) During 1976, Y has net bad debts charged to the reserve for losses on loans of $1,000. On December 31, 1976, Y has $1,000,000 in outstanding eligible loans. At the close of 1975 (Y's base year for 1976), the amount of outstanding eligible loans was also $1,000,000. Consequently, there is a reserve deficiency of $1,000 ((1.2% × $1,000,000)—$11,000). The maximum reasonable addition to the reserve for losses under subparagraph (1)(ii)(A) of this paragraph is $1,200 which consists of one-fifth of the reserve deficiency ($1,000 × 1/5 = $200) and the net bad debts charged to the reserve for losses on loans for the year ($1,000). Because that amount is less than 0.6 percent of the eligible loans outstanding at the close of the taxable year (0.6% × $1,000,000 = $6,000), the limitations of this subparagraph do not apply. Assuming that Y makes an addition to the reserve for losses on loans of $1,200 for the year, the balance of the reserve as of December 31, 1976, is $11,200 ($11,000−$1,000 + $1,200).
In the case of taxable years beginning after 1987, the initial balance of the reserve at the end of the year of change shall be the amount specified in subdivision (ii) of this subparagraph.
The T Bank is a commercial bank which has a calendar year as its taxable year. T adopted the reserve method of accounting for bad debts in 1950. On December 31, 1969, T has $1,000,000 of outstanding eligible loans and a balance of $19,300 in its reserve for losses on loans.
(a) During 1970, T has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1970, T has $1,050,000 of outstanding eligible loans. T elects the percentage method. The base year is 1969. The maximum reasonable addition under the percentage method of $1,000 which is the amount sufficient to increase the balance of the reserve as of the close of the taxable year to the balance of the reserve as of the close of the base year 1969 ($19.300). Assuming that T makes an addition to the reserve for losses on loans of $1,000 for the year, the balance of the reserve for losses on loans as of December 31, 1970, is $19,300 ($19,300−$1,000 + $1,000).
(b) During 1971, T has net bad debts of $8,000 charged to the reserve for losses on loans. On December 31, 1971, T has $1,100,000 of outstanding eligible loans. T elects the experience method. The base year is 1970. The maximum reasonable addition under the experience method is $8,000 which is the amount sufficient to increase the balance of the reserve as of the close of the taxable year to the balance of the reserve as of the close of the 1970 base year ($19,300). Assuming that T makes an addition to the reserve for losses on loans of $8,000 for the year, the balance of the reserve for losses on loans as of December 31, 1971, is $19,300, ($19,300−$8,000 + $8,000).
(c) During 1972, T has net bad debts of $1,000 charged to the reserve for losses on loans. On December 31, 1972, T has $1,200,000 of outstanding eligible loans. T elects the percentage method. The base year is 1971 and there is a reserve deficiency of $500 ((1.8% × $1,100,000)−$19,300). The maximum reasonable addition under the percentage method is $2,900 which consists of $100 of reserve deficiency ( 1/5 × $500), the $1,000 in net bad debts charged to the reserve for losses on loans, and $1,800 attributable to the increase in the balance of eligible loans (1.8% × ($1,200,000−$1,100,000)). Assuming that T makes an addition to the reserve for losses on loans of $2,900 for the year, the balance of the reserve for losses on loans as of December 31, 1972, is $21,200 ($19,300−$1,000 + $2,900).
For purposes of (B) of this subdivision (i), a bankers acceptance shall be considered as a loan made by the bank which purchased or discounted the bankers acceptance and not a loan made by the originating bank.
