Deferred Tax Asset – The Company has a net deferred tax asset of $51.9 million subject to a full valuation allowance at September 30, 2017. Our ability to utilize deferred tax assets depends upon generating sufficient future levels of taxable income. The determination to restore a deferred tax asset and eliminate a valuation allowance depends upon the evaluation of both positive and negative evidence regarding the likelihood of achieving sufficient future taxable income levels. A key element of the evaluation is the achievement of pre-tax net income rather than pre-tax net loss on a cumulative basis for the trailing three-year period. At September 30, 2017, our trailing three-year cumulative pre-tax net loss has declined to $762,000. We continue to monitor and evaluate the positive and negative evidence and will reverse the valuation allowance when we determine it is more-likely-than-not the asset will be utilized to reduce future taxes payable related to the future taxable income of the Company. Deferred Tax Asset (DTA) 17

Deferred Tax Asset 18 As of 9.30.2017, PBIB’s net DTA totaled approximately $51.9 million against which it carries a full valuation allowance. Deferred tax assets and liabilities are measured using current enacted tax rates (currently 35%).The valuation allowance can be reversed over time to offset future taxable income.Currently, none of the deferred tax asset is included in regulatory capital.DTA capital accretion presents potential upside capital enhancement.Section 382 of the Internal Revenue Code governs DTA impairment and “ownership change”.An “ownership change” is defined as a more than 50% change in ownership – complex assessment .382 imposes an annual ceiling on future use of the Company’s NOLs, credit carry-forwards and built-in losses.Tends to slow rate of NOL utilization (reducing present value of tax savings).Some NOLs and other tax benefits could expire before utilization is allowed.In June 2015, PBIB adopted a tax benefits preservation plan.Under Section 382 of the IRS Code, a permanent impairment of a substantial portion of the DTA could be triggered if shareholders owning 5% or more of the Company increase their ownership by more than 50 percentage points over a defined period of time.The tax benefits preservation plan is designed to reduce the likelihood of an “ownership change”.Any shareholder or group that acquires ownership of 5% or more of the Company could be subject to significant dilution in its holdings if our Board does not approve such acquisition.Existing shareholders of 5% or more are also subject to dilution if they increase their holdings without Board approval.In September 2015, shareholders approved an amendment to the articles of incorporation to further protect the long-term value of the Company’s NOLs.The amendment provides a means to block transfers of our common shares that could result in an ownership change under Section 382.
