Answer the following question:

At the end of 20X8, Jon Corp., a public company had the following balances:

Deferred income tax liability related to accounts receivable $ - 198,000

Deferred income tax liability related to capital assets $ - 432,000

Deferred income tax asset related to warranties $54,000

Deferred income tax liability, per SFP $576,000

In 20X8, the company had reported $1,350,000 of taxable income. It also reported a $550,000 long-term receivable, taxable when collected. At the end of 20X8, capital assets had a net book value of $4,800,000 and a UCC of $3,600,000. Estimated warranty liabilities were $150,000.

In 20X9, Jon reported accounting earnings of $2,250,000. Collections on the long-term receivable amounted to $420,000. There were nondeductible golf club dues of $32,000. Warranty expense was equal to claims paid. Depreciation was $200,000 and CCA was $300,000. The tax rate was 38%.

The accounting basis for warranty is -150000. How was the -150000 calculated? Is the formula to calculate this warranty claims paid - warranty expense or is that incorrect? Explain and show you calculation. Do not say we cannot determine the precise accounting basis for warranty as the answer is -150000.
